  • Patent number: 6123577
    Abstract: The present invention discloses a new and novel patch panel and wall unit assembly for use in local area network (LAN) wiring and installation. The patch panels and wall units include a new printed circuit board designed to simplify the installation of LAN's. The patch panels are designed to more closely mimic the wall unit configuration so that more understandable wiring layouts can be presented during LAN wiring installation.

  • Patent number: 5279294
    Abstract: Hand-held shirt-pocket portable instrument for quantitative measurement of glucose or analysis in biological fluids. The system accepts a disposable diagnostic reagent test device which has a reagent carrier and mode of identifying to the instrument the reagent lot characteristics. The instrument includes a housing structure having a visual LCD readout, a microprocessor, and photosensing circuitry which measures the change of color of the reagent carrier upon reaction in the reacting chemistry of the disposable test device. The housing also includes a spring arrangement for actuating a disposable lancet into the skin for generating blood. The disposable diagnostic reagent unit includes a configuration for transporting of the blood in the regent unit. The system includes verification and calibration sequences for the electronics, the chemistry of an unused disposable unit, the presence of a blood sample, and the ambient temperature. The system also provides for storing a plurality of analysis readings.

  • Patent number: 4361730
    Abstract: A security terminal for use with a two-way interactive cable system. The security terminal develops alarm and supervisory signals, and controls their transmission over the cable when polled by a central station. The terminal discriminates between four different types of alarm condition (burglary, fire, medical and general emergency), and transmits respective coded signals over the cable, or over a switched telephone network if cable transmission is not successful. To further insure that alarm signals are properly transmitted in the event of a cable outage, the terminal responds to a cable-sent test command from the central station by causing the dialer to dial the central station over the switched telephone network; in this way, the dialer mechanism can be tested periodically to insure that it will be operative if needed.
