As I kid, I sometimes got frustrated with what I saw as my Dad not giving me a straight answer. For instance, I would say, “Dad, I need a hammer”. “What are you using it for?” he would say. “There’s a finishing nail sticking out the wooden floor in my room and I need to pound it back in.” (I grew up in an very old farm house.) “Then you need a rubber mallet, not a hammer.
Spectrum Control introduced metric threaded EMI filters with an M3 X 0.5 Feed-thru circuit and an M4 X 0.7 Pi circuit. The filters are easily mounted in a tapped hole or thru-hole and have a hex head dimension across the flats of 4.0 mm. The metric threading makes these EMI filters appropriate for designs in European and Asian markets. Spectrum's metric threaded EMI filters have capacitance values ranging from
American Bright Optoelectronics’ Brite-X LED devices offer a low power approach to solid state lighting (SSL) design that reduces thermal management issues and still maintains an LED system efficacy of nearly 70 lumens per Watt (4200K CCT). The system is entirely modularized, allowing system designers total freedom to choose the appropriate number of LEDs per module or the total aggregate number of modules and their geometric layout to achieve desired luminaire output.
XLoom Communications introduced its iFlame optical chip, a multichannel, high-density, cost-effective, optical engine for grid computing and data center applications. iFlame, a chip-scale four-channel optical transceiver, is aimed at data center applications running over InfiniBand, Ethernet and Fiber Channel. The chip, implemented as an optical engine, enables high-speed, high-density interconnect applications such as Opto-electrical media converters, optical active connectors and cables as well as traditional transceivers
Mitsubishi Electric announced the development what it claims to be the first worldwide compact and pluggable 10 Gbps optical communications transceiver (MF-10KWXF series) capable of optional tuning of DWDM (dense wavelength division multiplexing) in the entire C-band. The transceiver complies with the 10 Gbps form factor industrial standard XFP-E (small form factor pluggable extended) MSA
AMD introduced the Quad-Core AMD Opteron. Designed from inception for datacenters, Quad-core processors with the company’s Direct Connect Architecture introduce innovations that go beyond four x86 processing cores on a single die of silicon.
Minmax's MSLU100-Series 1W DC/DC consists of 21 models that operate over input voltage ranges of 5VDC, 12V DC and 24V DC which provide precisely regulated output voltages of 3.3V, 5V, 12V, 15V, ±5V, ±12V and ±15VDC. They meet IPC/JEDEC J-STD-020C 4th and 5th chapter in solder-reflow for lead free process, are in "gull-wing" SMT package, and weigh 1.2g.
Designers are always on the lookout for semiconductors and algorithms that help to boost the efficiency of appliances with a minimum addition to the overall system cost. Motor-control systems need to compensate for system input changes and can use control algorithms to ensure the efficient operation of the motor. Using advanced algorithms, such as a field oriented control (FOC), motor torque can be controlled dynamically, keeping it constant within the rated speed range (see Figure 1). Toward this, the most commonly used motor-control loop is the Proportional Integral Derivative (PID) controller, which comprises error calculation (reference minus measured variable), compensator (controller), and output generation to the system.
Consumer electronics manufacturers must develop completely different television receiver product designs for different countries or regions. The standards and technologies for television reception vary considerably so it has been impractical to consider a single flexible design covering multiple standards or regions. However, new technologies are emerging which will make it possible to have a single product design address multiple countries or regions.
Years ago I ditched my 9600 bps modem, but I still rely on dial-up modems. Those modems exist in automated teller machines, gasoline pumps, traffic controllers, medical instruments, security systems, point-of-sale (POS) equipment, and other devices. According to several sources, dial-up modems still provide the largest number of access points to the Internet. Fortunately, several OEM vendors supply dial-up modem modules that offer drop-in communications in small packages.
Backplanes serve as the central nervous system in a great many electronic products from industrial controls to telephone exchanges. In a typical backplane, front-side connectors hold boards in place and conduct signals from board to board and to I/O connectors. Without carefully designed backplanes, engineers could not extend the state of the art in computer and communication equipment. Engineers can buy off-the-shelf backplanes for a variety of standard buses such as VME, VME64, VME64x, CompactPCI (cPCI), PCI Express and even for an older bus such as STD-32. If necessary, they can customize a standard backplane or create one of their own.
Sensoray announced the addition of the model 335 to their PC/104 line of products,. The PC/104+ module supports CardBus and PC cards (PCMCIA). It will support two Type I or Type II 32 bit PC cards or one Type III allowing the expansion of additional functions such as: 10/100/1000 Mbps wireless Ethernet adapters, biometrics readers, Bluetooth cards and GPS cards.
National Semiconductor Corporation introduced what is said to be the industry’s first common-anode, current-mode, high-brightness light-emitting diode (LED) driver with pulse-width modulation (PWM) dimming. The LM3433 drives high-power, high-brightness LEDs in backlighting, projector and solid-state lighting applications.
Energy News: Congratulations to the students of Technishe Universität Darmstadt for winning the 2007 Solar Decathlon's top prize of US $100,000. The event involved students from 20 schools who all brought solar-powered homes to the National Mall in Washington, D.C. There are beautiful pictures and videos but here are some of mine from
Schaefer, Inc. introduced the C300 Series of 150W DC/DC Converters, AC/DC Power Supplies. The C300 DC/DC product line boasts 7 DC input ranges of 10V to 16V, 18V to 36V, 36V to 75V, 45V to 90V, 80V to 160V, 160V to 320V, and 320V to 380V with 10 single output voltages ranging from 5V DC to 220V DC.
