  • Model test apparatus and method
    Patent number: 6418806
    Abstract: The fire resistance of components normally subject to a standard flame test is evaluated using low temperature model tests. Reynolds number, Froude number, the pressure ratio of the flame to the surrounding atmosphere are matched in the modelling parameters and account is taken of the Prandtl number. Also, the model flow is controlled so as to match the change of momentum flux ratio in the flow through the burner used in a standard flame test. The method allows testing of easily produced model components at temperatures less than 90° C., with savings of cost and time.

  • Multiple-phase clock signal generator for integrated circuits, comprising PLL, counter, and logic circuits
    Patent number: 5517147
    Abstract: A multiple-phase clock signal generator includes a phase-locked loop (PLL) for generating an oscillating signal having a predetermined frequency, a counter driven by the oscillating signal and having a plurality of outputs, and a plurality of combinational logic gates each having a plurality of inputs and an output. Selected ones of the inputs of each combinational logic gate are coupled to selected outputs of the counter to produce, at the output of each combinational logic gate, a clock signal having a particular phase. Different combinations of the outputs of the counter can be used to generate different phases.

  • On chip noise tolerant temperature sensing circuit
    Patent number: 5213416
    Abstract: A novel on-chip temperature sensing circuit includes a differential voltage source which comprises a plurality of branches each of which is provided with temperature sensitive transistor means. The differential output from the differential voltage source is coupled to the inputs of a high gain differential amplifier and the outputs from the high gain differential amplifier are connected to a second stage differential amplifer and one of the branches of the second stage differential amplifier is coupled to a high gain transistor amplifier which is connected to an output pin on the semiconductor chip so that the signal at the output pin is a noise tolerant voltage indication of the temperature of said semiconductor chip which may be monitored during actual online operations. A hysteresis feedback may be coupled between one of the outputs of the differential amplifiers to provide a hysteresis feedback loop and rapid switching of the second differential amplifier.
