クッキー黄昏

http://anond.hatelabo.jp/20130922234233

の続き

今のクッキークリッカーの状態は、総生産量2京枚超で、毎秒219億枚のペース

ほとんどの実績をクリアして残りは、反物質コンデンサを後5個増やして

100個にするぐらいしか残ってません

96個目の反物質コンデンサの値段は2335兆クッキーなので、

この生産ペースでは1万秒以上、つまりざっと時間かかることになり、

1個ごとに1.15倍で価格クッキー)があがるので、さら時間

かかります

からこの状態になるとやることは2~3分に一度出てくるゴールデンクッキー

クリックするが重要である、というかそれ以外にやることがありません。

けどそのボーナスも20兆クッキーぐらいなので100回以上クッキー拾わないと

次のコンデンサー買えない・・・・・・

ということもなく、実はCPS7倍と20分のクッキーというゴールデンクッキー

コンボざっと180兆クッキーをゲットできることもあります

ですから次のコンデンサ買うのにはゴールデンクッキーを少なくとも20回以上は

ゲットしなくてはならず、その出現頻度を考えるとやっぱり1時間コースですかね

その先は実績やアップグレードもなくなるので、完全にゴールデンクッキーをゲット

するか、放置だけのゲームになってしまい、現実的なプレイ時間でのクッキー獲得

上限値も限界にきています

結局、イベントクリアする都度に加速感が指数的に増えていくという快感中毒

もここで尽きてしまます・・・

と思うところが、そこで終わらせないのが作者のうまいところで

この段階でリセットすると、これまでのクッキーの総生産量に応じてHeavenly Chip

というものをもらえて、クッキー生産効率最初から下駄をはかせて再度

最初からスタートでき、最初フェーズの加速感が半端ないです。

400%増しぐらいでスタートするため、最初反物質コンデンサ獲得まで1時間

かかんないんじゃないですかね。

このゲームの特徴であるイベントごとの加速感のインフレというものを、新たな

イベントを追加するだけでなく、ゲームそれ自体を単位としてその加速感を加える

というのは面白いアイデアです

ですから、「放置ゲームになってつまらん」という人は、その時点で一度リセット

することで、また新たな加速感を楽しめ、前回よりはずっと先まで放置ゲームという

ことを感じずに楽しめるわけですね

一週目でアップグレード全部揃えるのは、まあできないことはない範囲ですが、

作者の意図としてはリセットを何回か繰り返して到達してもらうのというのが

ゲームバランスとして適当と判断してるのかもしれません

ゴールデンクッキー7777枚獲得というチートなしではどんだけかかるか

 わからない隠し実績もあるわけですし) <h3>o- **********************************</h3>

以下、ゴールデンクッキーコンボについて詳細

ゴールデンクッキーによるボーナスはこの段階では、

・CPSが7倍になる。継続時間154秒

ボーナスクッキー現在クッキーの10%または20分の少ない方、+13枚

が、ほぼ半々の確率で得られます。(他の低確率ボーナスについて割愛

CPS7倍154秒というのは結局CPSの924倍のクッキーをもらえることに等しい

現在のCPSならば21兆枚

ボーナスのほうは、CPSの1200倍なのでもうちょっともらえて、26兆枚ですが、

いずれにせよ、コンデンサを買うにはその100倍は必要なわけで・・・

そこで効いてくるのがCPS7倍の継続時間が154秒というところ

ゴールデンクッキーの出現頻度は(この段階で)75秒から210秒なので、CPS7倍

状態でさらゴールデンクッキーが出現することがあり、ここでボーナスクッキー

ゲットできると先の7倍、つまり184兆枚もらえることになります

(ただし現在クッキー数がこの10倍以上、つまり1.8京枚以上残していることが

必要です。よってこの終盤の状態では、稼いだら新規生産手段に交換する、のではなく、

蓄財から利子をもらう、という戦略が優位になるわけです。

Types of digital cameras

Digital cameras are made in a wide range of sizes, prices and capabilities. The majority are camera phones, operated as a mobile application through the cellphone menu. Professional photographers and many amateurs use larger, more expensive digital single-lens reflex cameras (DSLR) for their greater versatility. Between these extremes lie digital compact cameras and bridge digital cameras that "bridge" the gap between amateur and professional cameras. Specialized cameras including multispectral imaging equipment and astrographs continue to serve the scientific, military, medical and other special purposes for which digital photography was invented.

[edit]Compact digital cameras

Subcompact with lens assembly retracted

Compact cameras are designed to be tiny and portable and are particularly suitable for casual and "snapshot" uses. Hence, they are also called point-and-shoot cameras. The smallest, generally less than 20 mm thick, are described as subcompacts or "ultra-compacts" and some are nearly credit card size.[2]

Most, apart from ruggedized or water-resistant models, incorporate a retractable lens assembly allowing a thin camera to have a moderately long focal length and thus fully exploit an image sensor larger than that on a camera phone, and a mechanized lens cap to cover the lens when retracted. The retracted and capped lens is protected from keys, coins and other hard objects, thus making it a thin, pocketable package. Subcompacts commonly have one lug and a short wrist strap which aids extraction from a pocket, while thicker compacts may have two lugs for attaching a neck strap.

Compact cameras are usually designed to be easy to use, sacrificing advanced features and picture quality for compactness and simplicity; images can usually only be stored using lossy compression (JPEG). Most have a built-in flash usually of low power, sufficient for nearby subjects. Live preview is almost always used to frame the photo. Most have limited motion picture capability. Compacts often have macro capability and zoom lenses but the zoom range is usually less than for bridge and DSLR cameras. Generally a contrast-detect autofocus system, using the image data from the live preview feed of the main imager, focuses the lens.

Typically, these cameras incorporate a nearly silent leaf shutter into their lenses.

For lower cost and smaller size, these cameras typically use image sensors with a diagonal of approximately 6 mm, corresponding to a crop factor around 6. This gives them weaker low-light performance, greater depth of field, generally closer focusing ability, and smaller components than cameras using larger sensors.

Starting in 2011, some compact digital cameras can take 3D still photos. These 3D compact stereo cameras can capture 3D panoramic photos for play back on a 3D TV.[3] Some of these are rugged and waterproof, and some have GPS, compass, barometer and altimeter. [4]

[edit]Bridge cameras

Sony DSC-H2

Main article: Bridge camera

Bridge are higher-end digital cameras that physically and ergonomically resemble DSLRs and share with them some advanced features, but share with compacts the use of a fixed lens and a small sensor. Like compacts, most use live preview to frame the image. Their autofocus uses the same contrast-detect mechanism, but many bridge cameras have a manual focus mode, in some cases using a separate focus ring, for greater control. They originally "bridged" the gap between affordable point-and-shoot cameras and the then unaffordable earlier digital SLRs.

Due to the combination of big physical size but a small sensor, many of these cameras have very highly specified lenses with large zoom range and fast aperture, partially compensating for the inability to change lenses. On some, the lens qualifies as superzoom. To compensate for the lesser sensitivity of their small sensors, these cameras almost always include an image stabilization system to enable longer handheld exposures.

These cameras are sometimes marketed as and confused with digital SLR cameras since the appearance is similar. Bridge cameras lack the reflex viewing system of DSLRs, are usually fitted with fixed (non-interchangeable) lenses (although some have a lens thread to attach accessory wide-angle or telephoto converters), and can usually take movies with sound. The scene is composed by viewing either the liquid crystal display or the electronic viewfinder (EVF). Most have a longer shutter lag than a true dSLR, but they are capable of good image quality (with sufficient light) while being more compact and lighter than DSLRs. High-end models of this type have comparable resolutions to low and mid-range DSLRs. Many of these cameras can store images in a Raw image format, or processed and JPEG compressed, or both. The majority have a built-in flash similar to those found in DSLRs.

In bright sun, the quality difference between a good compact camera and a digital SLR is minimal but bridgecams are more portable, cost less and have a similar zoom ability to dSLR. Thus a Bridge camera may better suit outdoor daytime activities, except when seeking professional-quality photos.[5]

In low light conditions and/or at ISO equivalents above 800, most bridge cameras (or megazooms) lack in image quality when compared to even entry level DSLRs. However, they do have one major advantage: their much larger depth of field due to the small sensor as compared to a DSLR, allowing larger apertures with shorter exposure times.

A 3D Photo Mode was introduced in 2011, whereby the camera automatically takes a second image from a slightly different perspective and provides a standard .MPO file for stereo display. [6]

[edit]Mirrorless interchangeable-lens camera

Main article: Mirrorless interchangeable-lens camera

In late 2008, a new type of camera emerged, combining the larger sensors and interchangeable lenses of DSLRs with the live-preview viewing system of compact cameras, either through an electronic viewfinder or on the rear LCD. These are simpler and more compact than DSLRs due to the removal of the mirror box, and typically emulate the handling and ergonomics of either DSLRs or compacts. The system is used by Micro Four Thirds, borrowing components from the Four Thirds DSLR system.

[edit]Digital single lens reflex cameras

Cutaway of an Olympus E-30 DSLR

Main article: Digital single-lens reflex camera

Digital single-lens reflex cameras (DSLRs) are digital cameras based on film single-lens reflex cameras (SLRs). They take their name from their unique viewing system, in which a mirror reflects light from the lens through a separate optical viewfinder. At the moment of exposure the mirror flips out of the way, making a distinctive "clack" sound and allowing light to fall on the imager.

Since no light reaches the imager during framing, autofocus is accomplished using specialized sensors in the mirror box itself. Most 21st century DSLRs also have a "live view" mode that emulates the live preview system of compact cameras, when selected.

These cameras have much larger sensors than the other types, typically 18 mm to 36 mm on the diagonal (crop factor 2, 1.6, or 1). This gives them superior low-light performance, less depth of field at a given aperture, and a larger size.

They make use of interchangeable lenses; each major DSLR manufacturer also sells a line of lenses specifically intended to be used on their cameras. This allows the user to select a lens designed for the application at hand: wide-angle, telephoto, low-light, etc. So each lens does not require its own shutter, DSLRs use a focal-plane shutter in front of the imager, behind the mirror.

[edit]Digital rangefinders

Main article: Rangefinder camera#Digital rangefinder

A rangefinder is a user-operated optical mechanism to measure subject distance once widely used on film cameras. Most digital cameras measure subject distance automatically using electro-optical techniques, but it is not customary to say that they have a rangefinder.

[edit]Line-scan camera systems

A line-scan camera is a camera device containing a line-scan image sensor chip, and a focusing mechanism. These cameras are almost solely used in industrial settings to capture an image of a constant stream of moving material. Unlike video cameras, line-scan cameras use a single row of pixel sensors, instead of a matrix of them. Data coming from the line-scan camera has a frequency, where the camera scans a line, waits, and repeats. The data coming from the line-scan camera is commonly processed by a computer, to collect the one-dimensional line data and to create a two-dimensional image. The collected two-dimensional image data is then processed by image-processing methods for industrial purposes.

Further information: Rotating line camera

[edit]Integration

Many devices include digital cameras built into or integrated into them. For example, mobile phones often include digital cameras; those that do are known as camera phones. Other small electronic devices (especially those used for communication) such as PDAs, laptops and BlackBerry devices often contain an integral digital camera, and most 21st century camcorders can also make still pictures.

Due to the limited storage capacity and general emphasis on convenience rather than image quality, almost all these integrated or converged devices store images in the lossy but compact JPEG file format.

Mobile phones incorporating digital cameras were introduced in Japan in 2001 by J-Phone. In 2003 camera phones outsold stand-alone digital cameras, and in 2006 they outsold all film-based cameras and digital cameras combined. These camera phones reached a billion devices sold in only five years, and by 2007 more than half of the installed base of all mobile phones were camera phones. Sales of separate cameras peaked in 2008. [7]

Integrated cameras tend to be at the very lowest end of the scale of digital cameras in technical specifications, such as resolution, optical quality, and ability to use accessories. With rapid development, however, the gap between mainstream compact digital cameras and camera phones is closing, and high-end camera phones are competitive with low-end stand-alone digital cameras of the same generation.

[edit]Waterproof

Waterproof digital cameras are digital cameras that can make pictures underwater. Waterproof housings have long been made but they cost almost as the cameras. Many waterproof digital cameras are shockproof and resistant to low temperatures; one of them is Canon PowerShot D10, one of the first underwater digital cameras.

These cameras become very popular during the holiday season, because many people want to save the best moments from their holidays at the seaside. Waterproof watches and mobile phones were produced earlier. Most makers of digital cameras also produce waterproof ones and every year they launch at least one new model, for example Sony, Olympus, Canon, Fuji.

Healthways Mako Shark, an early waterproof camera,[8] was launched in 1958 and cost around 25 dollars. It was a huge camera and pictures were black and white.

Portable electronic equipment battery technology

1, about the trickle charge, rapid charging and stable battery charging algorithm

According to the energy requirements of the final application, a battery may contain up to 4 lithium ion or lithium polymer battery core, its configuration will have a variety of change, at the same time with a mainstream power adapter: direct adapter, USB interface or car charger. Remove the core quantity, core configuration or power adapter type difference, the battery has the same charge characteristics. So they charge algorithm. Lithium ion and li-ion polymer battery best charging algorithm can divided into three phases: trickle charge, rapid charging and stable charge.

trickle charge. For depth discharge core to charge. When core voltage in less than about 2.8 V, use a constant 0.1 C of the current charging for it.

fast charging. Core voltage trickle charge more than the threshold, improve the charging current rapid charging. Fast charging current should be lower than 1.0 C.

stable voltage. In the fast charging process, once the core 4.2 V voltage, stable voltage phase began. This is through the minimum charge current or timer or of the two joint to interrupt charge. When the minimum current below about 0.07 C, can interrupt charge. The timer is to rely on a default to trigger the timer interrupt.

Advanced battery charger with additional security function normally. For example, if the core temperature exceeds the given window, usually 0 ℃-45 ℃, charge will be suspended.

Remove some very low-end equipment, now on the market/li-ion polymer lithium ion battery solutions are integrated with the outer components or, in accordance with the characteristics of the charging to charge, this is not just to get better effect charge, but also for safety.

lithium ion/polymer battery charge is an example of applications-double input 1.2 A lithium battery charger LTC4097

LTC4097 can be used to exchange adapter or USB power supply for single quarter/polymer lithium ion battery. Figure 1 for double input 1.2 A lithium battery charger LTC4097 schemes. It USES constant current/constant voltage algorithm charging, from exchange adapter power charge, programmable filling up to 1.2 electric current A, and with USB power can be as high as 1 A, at the same time, automatic detection in each input voltage whether there. This device also provide USB the current limit. Applications include PDA, MP3 players, digital camera, light portable medical and test equipment and big color cellular phone. The performance characteristics: no external micro controller charging termination; The input power automatic detection and choice; Through the resistance from the exchange of charging adapter input can be as high as 1.2 A programming charge current; The resistance of programmable USB charging current is up to 1 A; 100% or 20% USB charging current set; The input power output and existing bias NTC (VNTC) pin as a 120 mA drive ability; NTC thermistors input (NTC) pin for temperature qualified charged; Pre-settings battery voltage with floating plus or minus 0.6% accuracy; Thermal regulation maximize charge rate and free hot air LTC4097 can be used to exchange adapter or USB power supply for single quarter/polymer lithium ion battery. The use of constant current/constant voltage algorithm charging, from exchange adapter power charge, programmable filling up to 1.2 electric current A, and with USB power can be as high as 1 A, at the same time, automatic detection in each input voltage whether there. This device also provide USB the current limit. Applications include PDA, MP3 players, digital camera, light portable medical and test equipment and big color cellular phone.

2, lithium ion/polymer battery scheme

Lithium ion/polymer battery charge scheme for different number of core, core configuration, and power types are different. At present mainly have three main charging scheme: linear, Buck (step-down) switch and SEPIC (booster and step-down) switch.

2.1 linear scheme

When the input voltage in big with the charger with sufficient clearance of core after opening voltage, it is linear scheme, especially 1.0 C fast charging current than 1 A big too much. For example, MP3 players usually only one core, capacity from 700 to 1500 mAh differ, full charge voltage is open 4.2 V. MP3 player power is usually the AC/DC adapter or USB interface, the output is the rule of 5 V; At this time, the linear scheme is the most simple, most charger of the efficiency of the scheme. Figure 2 shows for lithium ion/polymer battery solution linear scheme, basic structure and linear voltage neat device.

linear scheme charger application examples-double input Li + charger and intelligent power source selector MAX8677A

MAX8677A is double input USB/AC adapter linear charger, built-in Smart Power Selector, used for rechargeable single quarter by Li + batteries portable devices. The charger integration of the battery and the external power source and load switch charging all the power switch, so that no external MOSFET. MAX8677A ideal used in portable devices, such as smart phones, PDA, portable media players, GPS navigation equipment, digital camera, and digital cameras.

MAX8677A can work in independent USB and the power input AC adapter or two input either one of the input. When connecting external power supply, intelligent power source selector allows the system not connect battery or can and depth discharge battery connection. Intelligent power source selector will automatically switch to the battery system load, use the system did not use the input power supply parts for battery, make full use of limited USB and adapter power supply input. All the needed electric current detection circuit, including the integration of the power switch, all integration in the piece. DC input current highest limit can be adjusted to 2 A and DC and USB input all can support 100 mA, 500 mA, and USB hung mode. Charge current can be adjusted to as high as 1.5 A, thus support wide range of battery capacitive. Other features include MAX8677A thermal regulation, over-voltage protection, charging status and fault output, power supply good surveillance, battery thermistors surveillance, and charging timer. MAX8677A using save a space, hot enhanced, 4 mm x 4 mm, 24 of the pins TQFN encapsulation, regulations, work in exceptional temperature range (40 ~ + 85 ℃).

2.2 Buck (step-down) switch scheme

When A 1.0 C of the charging current more than 1 A, or the input voltage of the core than with high voltage open many, Buck or step-down plan is A better choice. For example, based on the hard drive in the PMP, often use single core lithium ion battery, the full of open is 4.2 V voltage, capacity from 1200 to 2400 mAh range. And now PMP is usually use the car kit to charge, its output voltage in a 9 V to 16 between V. In the input voltage and battery voltage is the voltage difference between high (minimum 4.8 V) will make linear scheme lowers efficiency. This kind of low efficiency, plus more than 1.2 A 1 C fast charging electric current, have serious heat dissipation problems. To avoid this kind of situation, will the Buck scheme. Figure 3 for lithium ion/polymer battery charger scheme Buck diagram, basic structure with Buck (step-down) switching voltage regulators completely the same.

2.3 SEPIC (booster and step-down) switch scheme

In some use of three or four lithium ion/polymer core series equipments, charger of the input voltage is not always greater than the battery voltage. For example, laptop computers use 3 core lithium ion battery, full charge voltage is open 12.6 V (4.2 V x3), capacity is 1800 mAh to 3600 mAh from. Power supply input or output voltage is 1 6 V AC/DC adapter, or is car kit, the output voltage in a 9 V to 16 between V. Apparently, the linear and Buck solutions are not for this group of batteries. This is about to use SEPIC scheme, it can in the output voltage is higher than when the battery voltage, can be in the output voltage less than when the battery.

3, and power detection algorithm is proposed

Many portable products use voltage measurements to estimate the remaining battery power, but the battery voltage and surplus power relationship but will with the discharge rate, temperature and battery aging degree of change, make this kind of method can top 50% margin of error. The market for longer to use product demand unceasingly strengthens, so the system design personnel need more accurate solution. Use capacity check plan come to measure battery or consumption of electricity, will be in a wide range of application power to provide more accurate estimate of the battery power.

3.1 power detection algorithm is one of the examples of application, function complete list, double the battery portable battery application design

power detection principle. Good capacity check plan at least to have battery voltage, temperature and battery electric current, measuring method; A micro 9 a; And a set of and the verification of the punishment power detection algorithm is proposed. Bq2650x and bq27x00 is full capacity check program function, with a measuring voltage and temperature of the digital converter (ADC) and a measuring electric current and charging sensor the asp. These capacity check plan also has a microprocessor, is responsible for the implementation of the Texas instruments power detection algorithm is proposed. The algorithm can compensate the lithium ion battery life.low self-discharge, aging, the temperature and discharge rate, and other factors. Chip embedded microprocessor as host system processor save these calculation burden. Capacity check program can provide remaining power state information, bq27x00 series products also offer surplus can Run Time (Run Time to Empty) host may at any Time to capacity check plan these information query, then LED indicator light through or displays will inform the user battery. Capacity check meter is very easy to use, the system processor need only configuration 12 C or HDQ communication drive can.

The battery circuit description. Figure 4 (a) can be used for identification of IC functions with typical application circuit batteries. According to the use of IC testing program is different, the battery needs to have at least three to four outside the terminal.

VCC and BAT pins will even to the battery voltage, so that for, C power and the battery voltage measurement. The battery is connected a grounding resistance smaller detection resistors, let capacity check meter high impedance SRP and SRN input can monitor sensor resistance on both ends of the voltage. Through testing the current flows through a resistor can be used to judge the battery or release the amount of electricity. Designers choose detection resistance value must be considered when resistance on both ends of the voltage can't more than 100 mV, low resistance may be more hours in current errors. Circuit board layout must ensure that SRP and SRN to testing from as close as possible to the connection of the resistor sensor resistance end; In other words, they should be the Kelvin attachment.

HDQ pin need external and resistors, this resistance should be located the host or the main application, such capacity check plan to the battery and portable devices when sleep function enable connection broken. Advice and resistance choose 10 k Ω.

battery identification. A low cost WeiMao batteries are getting more and more serious, these cells may not contain OEM requirements of security protection circuit. So, genuine battery may contain figure 4 (a) shows the appraisal circuit. When to identify the battery, the host to contain IC (bq26150, the function is cyclic redundancy check (CRC)) issued the battery packs a ask value (challenge), the CRC will contain battery according to this inquiry value and, in the building of the IC in CRC polynomial calculation the CRC value. CRC is based on the host of command and IC secret in the query of the definition of the CRC polynomial completed, the host in CRC values calculated with the calculation result of well battery comparison to identify the appraisal success.

Once the battery through the appraisal, bq26150 will issue commands to ensure that the host and quantity test plan of material lines between normal communication. When the battery connection interruption or to connect, the whole the identification process will be repeated again.

double the battery application. Figure 4 (b) for use bq26500 support double the typical application of lithium ion battery circuit. In order to support more battery, and this circuit is adding a adjustable regulators. Capacity check millions of BAT pin and the bottom of a battery anode linked to complete the variable voltage measurement of the battery.

Host to be able to read capacity check plan of variable voltage measurement battery, to make sure the end of discharging threshold and charging terminate threshold. As for the remaining state power (RemainingStateofCapacity), do not need to read can use directly.

The above bq2650x and bq27x00 etc capacity check plan provides the battery manufacturer a simple to use options, this scheme L [just measuring battery voltage to be precise, so these capacity check plan can be applied to various battery framework, and can support the battery identification and double the battery application '

3.2 power detection algorithm is an example of applications another, can apply to all kinds of general voltmeter new IC.

Today's many manufacturers can provide a variety of voltmeter IC,, the user can choose the suitable function device, to optimize the product price. Use voltmeter measurement of storage battery parameters, the separate architecture allows users in the host custom power measurement algorithm within. Eliminating embedded processor battery cost. On this to Dallase semicconductor company called cases of DS2762 chip for typical analysis. A new separate voltmeter IC, its structure see chart 5 (a) below.

DS2762 application characteristics

DS2762 is a single quarter of lithium battery voltmeter and protection circuit, integrated into a tiny 2.46 mm x 2.74 mm inversion of packaging. Due to internal integration for power detection of high precise resistance, this device is very save a space. It is the small size and incomparable high level of integration, for mobile phone battery and other similar handheld products, such as PDA, etc, are all very ideal. Integrated protection circuit continuously monitoring the battery voltage, over voltage and flow fault (charging or discharge period). Different from the independent protection IC, DS2762 allow main processor surveillance/control protection FET conduction state, such, can DS2762 through the protection of the power system and the control circuit implementation. DS2762 can also charge a battery consumption has depth, when the battery voltage within three V, provide a limit of the charging current recovery path.

DS2762 accurate monitoring battery current, voltage and temperature, the dynamic range and resolution of common satisfy any mobile communication product testing standards. The measurement of current for internally generated when the integral, realize the power measurement. Through the real-time, continuous automatic disorders correct, the precision of power measurement can be increased. The built-in measuring resistance due to eliminate manufacturing process and temperature and cause resistance change, further improve the precision of the voltmeter. Important data stored in 32 bytes, can add the lock EEPROM; 16 bytes of SRAM are used to keep dynamic data. And DS2762 all communication all through the 1-Wire, more communication interface node, minimize the battery and the connection to the host.
