  • Patent number: 9705824
    Abstract: A modular system uses point-to-point communication between field-programmable gate arrays (FPGAs) on a control module and each port module, respectively, to manage basic module functions, such as power, environmental monitoring, and health checks on the modules and their components. This allows a chassis to be managed without fully powering each card first, frees processors on the modules from having to perform health checks, allows dedicated resources to rapidly monitor the health of each card, and prevents one bad card from disabling management of all cards.

  • Publication number: 20010038547
    Abstract: Each device of a family of removable digital media devices may be plugged into a host to permits the host to store data in it or to retrieve data from it. The form factors of the digital media devices and the connector system used by them are compact for minimizing the volume of space occupied in portable devices and for easy storage. Preferably, the digital media devices of the family use serial memory requiring few power and signal lines, so that few electrical contacts are required. For example, a small number of durable contact pads form the contact arrays on the digital media devices, which in conjunction with corresponding contact pads mounted into a suitable socket provide for easy and convenient insertion and removal and for robust and reliable electrical contact over a long insertion lifetime. The digital media devices interface to the host either directly or through adapters.

  • Patent number: 6282504
    Abstract: A low power recording devices permits various flexible power options, including a no-battery option in which the recording device satisfies its entire power requirements from the telephone wall socket and from the RS-232 socket of a computer, and a no-battery option in which the recording device satisfies its entire power requirements from the power source for the mobile telephone. Neither no-battery option exerts a significant additional load on the power source. Voice signals are digitized and stored in low power non-volatile memory. Facsimile signals either are digitized and stored in low power non-volatile memory, or are decoded and stored in low power non-volatile memory. An audio recording and playback capability through an integrated speaker-microphone pair is provided.

  • Patent number: 6175517
    Abstract: Each device of a family of removable digital media devices (310, 320, 330, 340, 350 and 360) may be plugged into a host to permits the host to store data in it or to retrieve data from it. The form factors of the digital media devices in the family and the connector system used by the digital media devices are compact for minimizing the volume of space occupied in portable devices and for easy storage. Some embodiments (310, 320, 330, 350 and 360) provide an elongated compact form factor that provides easy and firm grasping for insertion and removal. The digital media devices of the family have respective body portions (312, 322, 332, 342, 352 and 362) preferably of a rigid or semi-rigid material. Preferably, the digital media devices of the family use serial memory requiring few power and signal lines, so that few electrical contacts are required.

  • Patent number: 6123827
    Abstract: A method is disclosed for reliably calibrating a sensor used in diagnostic sensing of a predetermined parameter, e.g., CO.sub.2 partial pressure, O.sub.2 partial pressure, or pH, of a solution such as blood, the method compensating for expected variations over time in the value of the parameter in a calibration solution. The parameter of the calibration solution has a predetermined initial value, and the solution is initially located within a container that is configured to allow the value of that parameter to vary over time in a predetermined manner. Supplying the calibration solution to the sensor causes the sensor to produce a calibration solution signal, which is compared with a calculated value for the parameter based on its expected variation over time, to produce a calibration factor. Thereafter supplying the test fluid to the sensor causes the sensor produces a test fluid signal, and this test fluid signal then is adjusted in accordance with the calibration factor.

  • Patent number: 6027479
    Abstract: An improved apparatus is disclosed for maintaining a medical assembly, e.g., a blood chemistry electrode assembly, filled with a bubble-free storage liquid for an extended storage time period. The apparatus achieves this result by connecting to the assembly a pressurized reservoir that supplies additional storage liquid, to replenish any storage liquid lost due to diffusion from the medical assembly.
