There is no doubt that REMote controls are extremely popular and it has become very hard to imagine a world without them. They are used to control all manner of house appliances like the TV
set, the stereo, the VCR, and the satellite receiver.
多遠程二極管溫度傳感器-Design Considerations for pc thermal management
Multiple RDTS (REMote diode temperature sensing) provides the most accurate method of sensing an IC’s junction temperature. It overcomes thermal gradient and placement issues encountered when trying to place external sensors. PCB component count decreases when using a device that provides multiple inputs.Better temperature sensing improves product performance and reliability. Disk drive data integrity suffers at elevated temperatures. IBM published an article stating that a 5°C rise in operating temperature causes a 15% increase in the drive’s failure rate. The overall performance of a system can be improved by providing a more accurate temperature measurement of the most critical devices allowing them to run just a few degrees hotter.The LM83 directly senses its own temperature and the temperature of three external PN junctions. One is dedicated to the CPU of choice, the other two go to other parts of your system that need thermal monitoring such as the disk drive or graphics chip. The SMBus-compatible LM83 supports SMBus timeout and logic levels. The LM83 has two interrupt outputs; one for user-programmable limits and WATCHDOG capability (INT), the other is a Critical Temperature Alarm output (T_CRIT_A) for system power supply shutdown.
The Maxim Integrated 71M6541-DB REV 3.0 Demo Board is a demonstration board for evaluating the 71M6541 device for single-phase electronic energy metering applications in conjunction with the REMote Sensor Inter-face. It incorporates a 71M6541 integrated circuit, a 71M6601 REMote Interface IC, peripheral circuitry such as a serial EEPROM, emulator port, and on-board power supply. A serial to USB converter allows communication to a PC through a USB port. The Demo Board allows the evaluation of the 71M6541 energy meter chip for measurement accuracy and overall system use.
Abstract: This application note discusses a design for a phantom antenna power-supply system compatible with theDigital Satellite Equipment Control (DiSEqC) communication standard, using the MAX16948 automotive dual, highvoltageLDO/switch. The presented application circuit provides a REMote antenna power supply and also enables onewaycommunication from the radio head unit to the REMote antenna. This system architecture offers flexibility inDiSEqC tone-burst frequency choice (100Hz to 30kHz), enabling users the ability to select the best frequency for theirapplication.

There has long been a need for portable ultrasoundsystems that have good resolution at affordable costpoints. Portable systems enable healthcare providersto use ultrasound in REMote locations such asdisaster zones, developing regions, and battlefields,where it was not previously practical to do so.
通過以太網(wǎng)遠程配置Nios II 處理器 應(yīng)用筆記
Firmware in embedded hardware systems is frequently updated over the Ethernet. For
embedded systems that comprise a discrete microprocessor and the devices it controls, the
firmware is the software image run by the microprocessor. When the embedded system
includes an FPGA, firmware updates include updates of the hardware image on the FPGA. If
the FPGA includes a Nios® II soft processor, you can upgrade both the Nios II processor—as
part of the FPGA image—and the software that the Nios II processor runs, in a single REMote
configuration session.
