  • Publication number: 20050073786
    Abstract: In at least one embodiment a fault sense circuit includes a current sense device, a voltage sense device, a power sense device, a sub-combination thereof or a combination thereof. The current sense device is positioned to sense a drive current provided to a load by a drive circuit. The voltage sense device is coupled across the current sense device and receives a threshold signal at a first input and provides an output signal on an output whose value is dependent upon whether a sense signal at a second input is above or below the threshold signal. A level of the threshold signal changes in response to a voltage level of a power supply that supplies the drive current to the drive circuit.

  • Patent number: 6025821
    Abstract: The vacuum fluorescent display (VFD) system of the inventive invention includes a display matrix including an array of anodes, a processor, at least two anode drivers, and a grid driver to selectively activate the anodes of the display matrix. The system of the instant invention alternatingly disables some of the output gates of the two anode drivers so that the anodes in the outer columns of anodes associated with the activated grids are, preferably, pulled to ground, while the anodes in the inner columns of anodes of the activated grids may respond to the display data output from the anode driver output gates that are not currently disabled.

  • Patent number: 5781716
    Abstract: A fault tolerant multiple network server system in which multiple servers concurrently act as back-up servers for each other even while they are providing their own server services to the system. Rather than having an unused server monitoring for failure of a primary server and taking over control, each is act upon the network, but when its partner should fail, it assumes control of these partner servers storage subsystem. In this way, processing power of both servers is available during normal operation, but they each provide back-up capability for the other.
