Common Mode Choke Finder Searches Across A Wide Range Of Frequencies


Common Mode Choke Finder Searches Across A Wide Range Of Frequencies
Coilcraft
February 12, 2016

Coilcraft’s Common Mode Choke Finder web tool allows users to search and compare hundreds of common mode filter options. Search results are presented in a clear table sorted by the highest impedance or attenuation, depending on the user’s input. The tool includes the ability to search across a range of frequencies, showing the minimum common mode impedance and attenuation across that entire range. Another column shows the differential mode attenuation. The finder also lets users analyze up to six different filters on single impedance and attenuation graphs. You can access the Common Mode Choke Finder at http://www.coilcraft.com/apps/finder/cmffinder.cfm

Sensors Enable Continuous Contactless Patient Monitoring


Sensors Enable Continuous Contactless Patient Monitoring

February 12, 2016
The SCA10H and SCA11H series Ballistocardiography (BCG) sensors are designed for continuous contact-less patient monitoring in elderly care centers, hospitals, or in the home. In addition to BCG techniques, they employ ultra-sensitive MEMS accelerometers to provide vital sign information such as Heart Rate (HR), Heart Rate Variation (HRV), Relative Stroke Volume (SV), Respiration Rate (RR), and bed occupancy. BCG sensors are available in two formats. The SCA10H-D01 is a solderable PCB module housing both the accelerometer and microcontroller with embedded algorithms. The SCA11H-A01 includes the SCA10H module coupled with a Wi-Fi transceiver that is packaged in an IP55 rated waterproof enclosure. Also, it can operate in either a local mode or cloud environment. Both the SCA10H and SCA11H are intended for integration into a user’s device or system. Murata Manufacturing Co., Ltd. Smyrna, GA 800-241-6574 770-436-1300 http://www.murata.com

MCUs Boast Best Energy Efficiency in ARM Cortex-M4 Class


MCUs Boast Best Energy Efficiency in ARM Cortex-M4 Class
STMicroelectronics
February 12, 2016

According to the EEMBC ULPBench tests for low-power microcontrollers (MCUs), the STM32L4 devices achieve 176.70 ULPMark-CP without the help of a buck converter that adds external components such as a coil and capacitor. The EEMBC CoreMark score of 273.55 at 80 MHz shows that the STM32L4 series delivers an unrivalled combination of high peak performance and energy efficiency. The STM32L471 combines up to 1 MB Flash with analog and audio features for projects that require no LCD controller or USB connectivity. The STM32L475 has a USB OTG Full Speed controller, and both devices have multiple timers, clock sources, and communication interfaces including CAN, SDMMC, USART, SPI, and I2C. The analog peripherals include 12-bit ADCs with 5 MSPS capability and power-saving modes, as well as two 12-bit DACs, two op-amps with built-in Programmable-Gain Amplifier (PGA), and two ultra-low-power comparators. Pricing is from $2.13 for the STM32L432KBU6 with 128KB Flash and 64KB SRAM in QFN-32 package, each/10,000.

Cold Chain Data Loggers Mind The Goods


Cold Chain Data Loggers Mind The Goods
Saelig Co. Inc.

EasyLog EL-CC-1 cold chain loggers are flat, 1.5" x 2" IP67-sealed devices that come pre-configured for use in one of three particular applications: chilled goods, frozen goods, and ripening goods. Operation entails pressing the start button for automatic logging, making it simple for use by any operator. During a logging session, pressing the button again will illuminate the status LEDs to give a quick indication if the temperature has exceeded an alarm condition at any point. Once the logging session has been completed, the IP67-rated plastic wallet may be torn open to reveal a conventional flat USB connector which can be plugged in to any Windows PC's USB port. Using the free EasyLog CC software allows for downloading and graphing the data for reporting and evaluation. Additional waterproof sealed bags are available for the repeated use. The loggers have a measurement range of -30ºC to +60ºC with an accuracy of ±0.5°C maximum (±1°F) and resolution of 0.1°C (0.1°F). Up to 32,600 readings at ten minute intervals may be stored in the device. The EasyLog EL-CC-1 Cold Chain Loggers are available now from $19 each. A video describing the dataloggers is available at https://youtu.be/Ll5tGgAMrNY
