みたいな人たちの言ってることも尤もで、変人アピールが痛々しいって思う人もいるんだろうけれど、ロジックの正確さを重視して「オタク代表でもないし、僕は変人でもないけれど、絵が好きなので絵日記書いてみました」みたいなキレのないタイトルにしたらそれこそ「共感できる人」まで読まなくなるわけで、アンチもファンも程よくいる今くらいが一番いいんだと思う。

■法って何？

年末になりテレビ各局はいろんな報道番組をやってる。

一番多いのはやはり震災関係で、それと共に原発の事故のこと。

当時、官邸で何が起こっていたか？とか、

東電は？とか、保安院は？とか…。

総理が非常事態宣言を出すのに時間がかかったのは

法体系が整ってなかったからだって言ってた。

そして今日。

新聞に「今年は死刑執行がない」って載ってた。

？？？

死刑が確定した場合は速やかに執行されるべきって

法になかったっけ？？

私の思い違い？？

法体系が整うってどういうことなんだろう？

整ってようがいまいが、運用する人間の匙加減なの？

学も教養もない私にはよくわからん。

でも、そういう多くの素人の為にプロがいるわけで。

政治家も官僚もプロとして仕事してくれなくちゃダメじゃん？

■Choose the best digital camera rechargeable batteries

Due to the nature of a digital camera, they need a lot of voltage and also need to keep good battery long periods of inactivity digital camera rechargeable batteries to a big hit, many current digital camera has a flash, may also make a short film, the two characteristics is very good, but can drain battery two times normal speed, photo shooting.

Most people are familiar with basic rechargeable battery, but the key to finding a good a doctor to give your digital camera is to look at the battery material, how will charge, and how long will the cost in use and sitting on the shelf or in the digital camera.

A little I look in my purchase any digital camera I buy is to ensure that there is a common battery size. The reason is, no matter how you plan a photo shoot, things happen, you may have to resort to the old alkaline batteries solve your problems, then. Panasonic battery my first choice is a rechargeable battery, but you never know, this is a very good thing can find a new set of batteries.

There are several important factors to consider, rechargeable batteries is the best. The first is the amount of voltage, followed by long time, then the battery of the time; Four is charge (how long shelf life will be held responsible for the storage battery).

Here are a series of typical rechargeable batteries and their voltage output:

Ni-Cad rechargeable battery, 12 volts

Nickel metal hydride rechargeable batteries-1.2 to 1.5

Ni-ZN rechargeable batteries-160 volts

Standard alkalines is 1.5 volts

Also have a level a reference number of energy storage, from the ability to represent called milli ampere hour. These level general fleeing to 2100 from 750 from is high, the more the number of the battery capacity (higher digital better).

The Ni-Cad and nimh most common, almost every major brand battery multiple versions. The latest technology is Ni-ZN are excellent storage capacity and long shelf life. Many types of rechargeable batteries can be charging many times, but they didn't mention that drop down power amount of recharges x.

And this is the real factors to consider. Let us say that if you find new battery you can use about 100 photos before they go to the south. Recharges Numbers increase, reduce many pictures. Some can only continue to before they start, recharges loose the ability to completely costs. Clever cost is still good savings from an ordinary AA alkaline battery cost $1.15 and the comparable charge is $2.50, according to the figures from $5.00.

Recent Ni-ZN cost about $5 each request and take over 500 recharges in any losses before the injury charge ability. But they also play more voltage so for example your flash recycling half the time to complete the normal alkaline batteries. If you have 100 threw a set of alkaline, you should get at least 175 vote of Ni-ZN are the same size. Plus storage life N-ZN than any other choice.

Rapid turnover a flash can be a big problem, because it is a very painful, but when photographs in the interior, need to wait for two minutes of the flash is full of power. Or, if you are shooting a series of short a minute video and ran out of the juice in the middle is not a good thing.

So, based on the pricing and ability, if you can recharge the battery is more than 500 times more the highest price, they use more cheap long-term development. If they hold up close to claim 500 cost, well, you can do the math. This is a no brainer, Ni-ZN provide more voltage, better life, and more fees each battery.

■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 configurat ion 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 configurat ion 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 add it ional 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 terminat ion; The input power automatic detection and choice; Through the resistance from the ex change 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 regulat ion 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 configurat ion, 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, capac ity 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 integrat ion 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 navigat ion 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 connect ion. Intelligent power source selector will automatic ally 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 integrat ion of the power switch, all integrat ion 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 capac itive. Other features include MAX8677A thermal regulat ion, 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 encapsulat ion, regulat ions, 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, capac ity 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 dissipat ion problems. To avoid this kind of situat ion, 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), capac ity 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 relat ionship 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 capac ity check plan come to measure battery or consumption of electric ity, 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 capac ity 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 verific at ion of the punishment power detection algorithm is proposed. Bq2650x and bq27x00 is full capac ity 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 capac ity check plan also has a microprocessor, is responsible for the implementat ion 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 calculat ion burden. Capac ity 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 capac ity check plan these information query, then LED indic ator light through or displays will inform the user battery. Capac ity check meter is very easy to use, the system processor need only configurat ion 12 C or HDQ communic at ion drive can.

The battery circuit description. Figure 4 (a) can be used for identific at ion 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 capac ity check meter high impedance SRP and SRN input can mon itor 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 electric ity. 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 connect ion 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 capac ity check plan to the battery and portable devices when sleep function enable connect ion broken. Advice and resistance choose 10 k Ω.

battery identific at ion. 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 calculat ion the CRC value. CRC is based on the host of command and IC secret in the query of the definit ion of the CRC polynomial completed, the host in CRC values calculated with the calculat ion 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 communic at ion. When the battery connect ion interruption or to connect, the whole the identific at ion 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. Capac ity 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 capac ity 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 (RemainingStateofCapac ity), do not need to read can use directly.

The above bq2650x and bq27x00 etc capac ity check plan provides the battery manufacturer a simple to use options, this scheme L [just measuring battery voltage to be precise, so these capac ity check plan can be applied to various battery framework, and can support the battery identific at ion 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 Dall ase 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 integrat ion for power detection of high precise resistance, this device is very save a space. It is the small size and incomparable high level of integrat ion, for mobile phone battery and other similar handheld products, such as PDA, etc, are all very ideal. Integrated protection circuit continuously mon itoring 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 implementat ion. 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 mon itoring battery current, voltage and temperature, the dynamic range and resolution of common satisfy any mobile communic at ion 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 communic at ion all through the 1-Wire, more communic at ion interface node, minimize the battery and the connect ion to the host. Its main features for; Single quarter of lithium battery protector; High precision current (power measurement), voltage and temperature measurement; Optional integrated 25 m Ω measuring resistance, each DS2762 after fine-tuning alone; 0 V battery restore charge; 32 bytes can lock EEPROM, 16 bytes SRAM, 64 a ROM;

・「オタク」としてまとめられてる趣味行動･奇行が浅すぎライトすぎ

・「過剰に論理的」とか「発想が人と違う」ではなく「凡人の変人ぶりっ子」なのがバレバレ

・一方で、本当に変というか、確かに非常識だな（それも単に悪い方向に）という部分がチラホラ見えるがそこには自覚がない

・作者の本当に変な部分は「理系」「オタク」に誤集約してスポイルする事でスルーしている

具体例でいうと　１

・寿司屋でネタの正式名称がどうのと因縁つけるのの何が面白い？

　冗談抜きに中学生ぐらいがいきがってやりそうな行動でしかない。

　これを本人は、読み物として提出出来るぐらい面白いネタだと思ってる。

　ずっとこの水準で「俺って面白い変人デショデショ？」なので、かなりキツい。

具体例でいうと　２

・作者の同期や彼女との人間関係だけは本当に変人というか、確かに人よりかなり劣っている。

　しかもこっちには見世物的な意識が感じられない。むしろなんかイジケたマジレスが多い。

　彼女との別れの顛末なんかも、自己中心的でナイーブな視野からの描写に終始し、

　「僕はこう感じて」「僕はこう疲れた」ばっかし。客観性・論理性が皆無。

　「理系」キャラが簡単に崩れて馬脚だし過ぎなのはもちろん、

　そのつまらん愚痴がカネとって人に読ませるようなものか考えてないのは

　これも自意識過剰のなせる技だと思う。

　「自分の思考・発想が普通の人と違うと自覚し意識する変人」て。

　それはどうやったって「自意識過剰･演出過剰な凡人」でしか有り得ない。

　『となりの８０１ちゃん』（読んだ事ねーけど）は

　非常識人である８０１ちゃんの世間とのギャップを

　常識人である８０１ちゃんの配偶者が観察日記的に述べていくんでしょ？

　変人や異界人を描写しネタとして提示していくにはこれしかないよね。

　『中国嫁日記』だって『ダーリンは外国人』だってそう。

繰り返すけど

　「俺ってこんなに変なんだよ」「ほら変でしょう」っていうのは変人ごっこにしかなりえないよね。

　構造からして頭が悪いし、変人ショーとしては凡人臭がき出すぎだし、自意識未整理すぎというもんだよ。

　中学生が書いてんなら良いけど、三十路のサラリーマンでそれはさあ。
