  • Reconfigurable I/O card pins
    Patent number: 8037223
    Abstract: In accordance with the present technique, a system and method for configuring pins of an input/output (I/O) card in a host system are provided. The method includes reading configuration information from a card field replaceable unit memory and reading system configuration information from a system field replaceable unit memory. Additionally, the method includes configuring pins of a system logic of the host system to be compatible with the I/O device of the I/O card, and configuring pins of an I/O device on the I/O card to in turn configure the pins of the I/O card with a configuration setting compatible with the host system.

  • Fault tolerant network server having multiple slideably-mounted processing elements sharing a redundant array of independent disks through SCSI isolators
    Patent number: 6618821
    Abstract: A fault tolerant network server is described. This server has a pair of processing units, each processing unit has at least one CPU, system memory, an interface for a RAID system, at least one disk drive, a network interface, a cluster network interface, a power supply, and a case. The cases of both processing units are slideably mounted in a rack-mountable server case. The server also has a RAID system mounted in the server case and powered by two, redundant, power supplies and coupled to the processing units through isolators for blocking transactions when a processing unit has insufficient power or is being serviced.

  • Method of measuring physiological function
    Patent number: 5928625
    Abstract: A method of measuring physiological function of a group of body cells, includes the step of selecting a detectable agent capable of emitting a measurable electromagnetic emission. The agent is introduced into body fluid which contacts the group of body cells. The emission is measured, and physiological function is determined based on measurement of the emission.
