  • Protecting the Universal Serial Bus from Over Voltage and Overcurrent Threats (.pdf)
    such as mice, modems and keyboards (see Figure 1). Additionally, a single hub permits the connection of several USB devices by providing power through the communication cable itself, eliminating the need for individually powered peripherals. It also allows mixed high-speed communications between USB
  • Computer Power User Article - Mighty Motherboard Toolbox
    would rise. After we unpackaged our new toy, we saw that the EL wire was molded to the side of the silvery cable, and as a result the cable was wider than normal. The lighting effects required the use of the included inverter, which connects to a four-prong power plug from the power supply. In bright
  • Power Plant Thermography - Part II
    , and today's PdM specialist is nearly invincible. This paper demonstrates some of the more interesting problems, and the tools used to identify them and bring them to closure. Faults include a hot spot in a cable connection for a large chiller, a hot bus bar connection in a critical panel, a complicated
  • Computer Power User Article - SLI Unleashed
    Back in the days when 3dfx muscled around smaller companies with its Voodoo lineup of graphics cards, the PCI bus was still a viable option for graphics cards. As a result, 3dfx developed a technology coincidentally also named SLI, although 3dfx's version stood for Scan Line Interleave. 3dfx's
  • Computer Power User Article - ASUS A7V880
    . The northbridge's synchronous bus architecture supports Athlon XP processors with FSB speeds up to 400MHz, AGP 4X and 8X compatibility, and DualStream64 technology. Dual-channel memory supplies up to 6.4GBps peak throughput with matched DDR400 SDRAM modules. The VT8237 southbridge manages two dual-channel
  • Protection for EOS for IEEE1394 Lines With TPD4S1394
    to electrical overstress damage when exposed to a combination of high-voltage cable power and a faulty cable or connector system that allows data (TPx) and cable power (Vp) connections to engage before the cable ground (Vg) connection. This set of circumstances is known as a "Late-Vg" event. Though
  • Various Interfaces for Rotary Encoders
    . The Synchronous-Serial- Interface (SSI) transmits data via a cable with just six cores (one twisted pair for data, one twisted pair for a clock signal and two cores for power supply). Benefits: The SSI transmission provides immunity to high noise. Drivers that meet the RS 485 standard allow
  • Sensible Sensing
    using off-the-shelf data-acquisition (DAQ) cards. The result: higher data speeds, easier installation, and flexibility in bus selection and operating systems. A conventional sensor system consists of a transducer, high-flex cable, and a controller to convert strain-gage input to force and torque
  • Open Network Eliminates Tray-Loader Wiring Problems
    " cable that carries power and data to a controller. To set up a system, the cable is positioned along the I/O point's path. The I/Os connect to the cable using AS-i snap-and-go piercing devices. One cable can connect a whole network of I/O points. If needed, a user can also add splitter modules
  • Tales from the Front: Applying Fieldbus at Genzyme, Part 1
    for the powered bus is known as chicken foot (Figure 5, below). Moreover, it would be difficult to identify the offending device without disconnecting devices one by one until the shorted device or cable was found. Short-circuit protection is normally provided for the segment trunk with the segment power
