On June 2, 2008, the Environmental Protection Agency (last seen as the supervillains in “The Simpsons” movie) released a “technical amendment,” version 4.2, to the Energy Star residential light fixture specification. Remember when Nintendo introduced the ubiquitous “Seal of Quality?” The great crash of 1983 was caused by a number of factors, not the least of which was lousy software...
Translating PROFIBUS to USB and vice versa, Grid Connect’s ProfiTrace 2 PROFIBUS analyzer incorporates a digital oscilloscope to capture bus signals running at 12 Mbps, display them using the Bit Interpretation Engine, indicate a problem’s distance, and the option to show one device’s signals. The DP-V0/DP-V1 class 1 and 2 master uses the Live List statistics matrix to list all available devices and information including retry messages
The recent cries over shoddy manufacturing performance have put electronic product designers in a tough spot – and frankly, left them baffled. Time after time, their design concepts that had the makings of a sure bet evolved into a product with deficiencies reported from thousands of customers – leaving many unanswered questions.
Supporting data ranges from 1.20 kb/s to 115.20 kb/s, Vishay Intertechnology’s TOIM5232 encoder/decoder presents proper pulse shaping of RS-232 data signals for serial infrared (SIR) IrDA transceivers. The device shortens RS-232 output signals to IrDA-compatible electrical pulses to drive an infrared transmitter in transmit mode, and
Integrating a cross-roller bearing structure, Oriental Motor’s DG 200 Series hollow rotary actuators shows a repetitive position accuracy of 15 arc-seconds and a total backlash of 2 arc-minutes. With a frame size of 7.87” (200 mm) and an internal hollow diameter of 3.94” (100 mm), the RoHS-compliant components develop
Having single or dual wavelength options at 1,310 nm or 1,550 nm, Agilent Technologies’ N4374B lightwave component analyzer (LCA) offers traceable electro-optical S-parameter testing for transmitters and receivers in CATV and Radio over Fiber applications. The device exhibits internationally-specified relative and
Networks Take High Performance Motion Control to the Next Level Networks simplify software development, axis coordination, code updates, and system characteristics.
Allowing DSP or processor aggregation, Tundra Semiconductor’s Tsi620 multi-standard RapidIO switch evaluation platform enables prototyping using Texas Instruments’ TMS320TCI6487 multi-core 3 GHz DSP with extendable cluster and an Altera Stratix III FPGA. The component offers communication with PCI-enabled microprocessors through a PMC connector, hardware bridging and leverage over XGMII. The platform includes
What are the most important factors to consider when developing a new product?
Phoenix Contact’s STEP Series of general-purpose power supplies utilize a voltage versus current characteristic output suitable for starting lamp loads or capacitive loads. The devices offer a DIN rail clip for mounting onto a rail or in a panel. The supplies are appropriate for small load applications in the building automation industry. Some models include
Designed as Von Weise drop-in replacements, Bison Gear & Engineering’s VWDIR line of fractional horsepower gearmotors deliver from 1/30 to ½ horsepower in commercial and industrial light applications. The parallel shaft and right angle devices offer output torques from 12 in./lbs to 800 in./lbs in over 75 models. DC models
Performing at 2.5 V, Fox Electronics’ F540 Series HCMOS oscillators exhibit stabilities of 15 ppm (F547), 10 ppm (F549) and 8 ppm (F54S) with phase noise of -140 dBc/Hz at 10 kHz offset and a jitter period of 3 ps rms. The 5 mm × 3.2 mm RoHS-compliant components presents an input current of 7 mA, output current of 4 mA and
Targeting the small- and medium-sized business (SMB) market, ADTRAN’s NetVanta 1234 PoE, NetVanta 1238 PoE and NetVanta 1534 PoE networking switches support Gigabit PoE while offering LLDP/LLDP MED, cable diagnostics and
On August 14th, 2008, The Mathworks held the kick-off to “EcoCAR,” a collegiate advanced technology vehicle competition (ATVC). EcoCAR’s subtitle (“The NeXt Challenge”) says it all- this is the spiritual successor to “Challenge X,” a similarly-themed ATVC contest that, last year, ended with Mississippi State University taking home the gold. In speaking with personnel from the DOE, The Mathworks, and GM (all event sponsors), I concluded that the biggest obstacle to ATV’s greater viability is a lack of young, qualified engineers.
Lasting for a lifespan of 25 years, ITT Interconnect Solutions’ SMA-Hi Temp RF connector system, consisting of a coaxial RF connector and 12 RF cable assemblies, uses a cable assembly with a silicone dioxide dielectric suitable for continuous operation at 250°C. The semi-rigid cable assemblies offer phase-matching to ±2° at 3 GHz and an option to be
