Energy News: There are biofuel critics who say America can never grow enough raw material for the technology to be affordable and ubiquitous, but some scientists believe algae is a better option. At the University of Minnesota, they're figuring out how to make algae grow very fast, and how to get up to 15,000 gallons of oil per acre -- that is 750 percent more yield than
LEDtronics announced the release of its DC/DC Dimmer for LED lighting products, supporting 5V DC to 40V DC applications up to 2A or 24W. LED-DIMMER-001 is suited for LED strip lights, LED bulbs and LED floodlights. Since LEDs draw less current than traditional incandescent bulbs, one had to buy a special high-end electronic dimmer to control the desired light levels for their LED lighting application.
Aveso, Inc. offers a commercially available Electronic Display Inlay for plastic card manufacturers. The inlay makes it possible to produce electronic display cards using industry standard hot lamination manufacturing processes and installed equipment. The inlay features the company’s Primero 6|7 flexible numeric display module, along with a battery and circuitry, embedded in a durable plastic structure
Atmel Corp. introduced 13.56 MHz RFID devices with a 64-bit cryptographic engine, dual authentication capability, and up to 64 Kb of memory, each with up to 16 individually configurable sectors. Atmel’s CryptoRF devices are suited for proximity applications that represent cash transactions, require a permanent record of the chain of ownership, or are prone to counterfeiting. CryptoRF devices have a 64-bit embedded
Enpirion introduced a 2A buck-mode device with integrated inductor technology. The company calls its EN5322QI the “LDO Killer,” which it positions as a replacement for linear regulators to meet Energy Star requirements. The part integrates all converter functionality including MOSFET switches, control and compensation, and the inductor, in a 6 mm × 4 mm × 1.1 mm QFN package, while requiring only
MEN Micro introduced the M36N M-Module, an analog input mezzanine board that provides high resolution and precise data acquisition for analog signals found throughout automation, measuring and simulation applications. Available in 16- or 18-bit versions, the board can be used as an I/O extension for CompactPCI, PCI, PXI or VME embedded systems as well as on stand-alone single board computers (SBCs).
C&K Components has developed a series of sound tunable tactile switches, designated the KSC ST Series. The design of the switch enables the sound intensity to be 100 percent controlled, with the ability to match the sound level of applications with two sound intensity grades. The company is also able to ensure continuity of the sound when a printed circuit board is populated with a number of switches.
Smart Modular Technologies expanded its DDR2 family to include what is said to be the industry’s first 8GB PC2-5300 244-pin Mini-registered DIMM (RDIMM) designed using CoolFlex and dual die package (DDP) technologies. The new Mini-RDIMM is suited for high-density, space-constrained networking and storage applications. Configured as a 1Gx72, four-rank module using SMART-built 2Gb (512Mx4) DDPs
Power factor is the ratio of the actual power used to the apparent (reactive) power that a piece of equipment draws from the alternating current (AC) line. The reactance of large capacitors or inductors can cause the apparent power drawn from the line to exceed the actual power used, resulting in low power factor (PF). The lower the PF, the more energy is lost along the AC power line. The result is higher electricity bills for the utility customer. That lost energy also lowers the capacity of the utility distribution system.
OKW Electronics has launched the CTB77 series high power PCB terminal blocks from Camden Electronics. These have been designed for heavy duty applications such as energy management, industrial heating and ventilation, and machine controllers. The terminal blocks can handle high currents of up to 57A. They are molded in gray UL94 V-0 flame retardant PA66, and are available in 2 and 3 pole interlocking types
Most likely you know a bit about the Controller Area Network, also called CAN or CAN bus, developed for communications between equipment in vehicles. The CAN has spread into embedded systems, too, but unlike chip-to-chip I2C or SPI connections, CAN communications may occur between cards and systems over a bus that can extend from 10's to 100's of meters. (The ISO-11519 and ISO-11898 standards covers CAN protocols and physical-layer specifications.)
Emerson Network Power launched four DC-input bulk front-end power modules for systems that use distributed power architectures. The modules add DC-input options to the company's DS series of power supplies. The DS450DC, 550DC, 650DC and 850DC modules all feature a very wide 40V DC to 72V DC input voltage range, which is suitable for telecom and central office applications operating from 48V battery plants.
NXP announced its high-voltage, full bridge fluorescent backlight controller IC the UBA2074 and its low-voltage twin, the UBA2072. Together, they form a family of full-bridge fluorescent backlight controller ICs, designed specifically to address the trend toward growing display sizes and supporting the increased use of high-supply voltage backlight inverters in LCD-TV applications.
Energy News: Three stories about energy efficiency, focusing on computers, landed in my inbox today -- with a big fat asterisk attached. The stories are: Google Plans Renewable Energy Push -- they want to make one a gigawatt of clean energy cheaper to produce than the same amount of coal; HP Enters Two Renewable-Energy Contracts -- they're using solar and wind power for facilities in San Diego and Ireland; and Climate Savers Computing Initiative Empowers Smarter Computing Choices -- there's an online catalog of green desktops and servers, but it's only for companies that pay to join
GlobTek introduced the GT-41xxx series of blade power supplies. The series features the GT-41076 with power up to 6W, GT-41052 up to 15W and GTM41060 up to 25W with constant current option. The regulated outputs voltage range from 5V to 48V DC in 0.1V increments, with up to 25W of continuous output power. The 64 mm × 40.5 mm × 29 mm polycarbonate impact resistant non-vented cases
