This matrix C++ template class library is for performing common matrix operations in your C++ program like any other built-IN data types. To install the package, just copy MATRIX.H file into the INCLUDE directory of your compiler and include this header file in your program source file
Oracle PL/SQL Best Practices is a concise, easy-to-use summary of best
practices in the program development process. It covers coding style,
writing SQL in PL/SQL, data structures, control structures, exception
handling, program and package construction, and built-IN packages.
使用TWAIN讀取掃描儀的圖像。In Windows imaging applications, the most used API for scanning is TWAIN www.twain.org. Unfortunately, the new .NET Framework has no built-IN support for TWAIN. So we have to work with the interop methods of .NET to access this API. This article doesn t explain this interop techniques, and good knowledge of the TWAIN 1.9 specifications is assumed! The sample code included doesn t present a finished library, only some essential steps for a minimal TWAIN adaption to .NET applications.
DC/DC 升壓IC：The FP6291 is a current mode boost DC-DC converter. Its PWM circuitry with built-IN 0.25 Ω
power MOSFET make this regulator highly power efficient. The internal compensation network also
minimizes as much as 6 external component counts. The non-inverting input of error amplifier connects
to a 0.6V precision reference voltage and internal soft-start function can reduce the inrush current.
The FP6291 is available in the SOT23-6L package and provides space-saving PCB for the application fields.
Industrial remote monitoring systems and keep-alivecircuits spend most of their time in standby mode. Manyof these systems also depend on battery power, so powersupply effi ciency in standby state is very important tomaximize battery life. The LT®8410/-1 high effi ciencyboost converter is ideal for these systems, requiringonly 8.5μA of quiescent current in standby mode. Thedevice integrates high value (12.4M/0.4M) output feedbackresistors, signifi cantly reducing input current whenthe output is in regulation with no load. Other featuresinclude an integrated 40V switch and Schottky diode,output disconnect with current limit, built in soft-start,overvoltage protection and a wide input range, all in atiny 8-pin 2mm × 2mm DFN package.
Most portable computers have built-IN sockets to acceptsmall PC cards for use as extended memories, fax modems,network interfaces, wireless communicators and awide assortment of other functions. The Personal ComputerMemory Card International Association (PCMCIA)has released specifications that outline the general powerrequirements for these cards.
