  • 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
    office light, the cable's glow was not that impressive. But in darker rooms, and with other mod-minded toys installed, these cables would be a nice touch. The RocketHead 100 SATA converter is designed to give your IDE hard drive a speed boost. It comes with the SATA power splitter you need for your
  • Computer Power User Article - SLI Unleashed
    improvement in available bandwidth from the AGP bus doomed 3dfx's SLI. Because of the design differences between the AGP and PCI buses, it was impossible to set up a system with two AGP cards. That didn't stop 3dfx from trying to innovate. With its Voodoo5 graphics card, 3dfx added a second core to simulate
  • 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 - 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
  • Tales from the Front: Applying Fieldbus at Genzyme, Part 1
    points. The buses selected for our facility fall into two distinct categories powered buses, including Foundation fieldbus and AS-i bus, and unpowered buses (Profibus-DP and DeviceNet). The powered bus includes the communications and device power on the same wires. The overall topology used
  • An Innovative Cabling Concept Improves Reliability for Multi-Axis Stage Systems
    shown in Figure 1, instead of a huge number of moving wires, there are 3 moving control modules, a tiny three wire shielded CAN-bus cable in a daisy chain configuration and two wires for power. In total, the complete system needs just 2 separate cables with diameters of 7 mm and 12 mm independent of how
  • 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
