  • Method/architecture for a low gain PLL with wide frequency range
    Patent number: 6680632
    Abstract: An apparatus comprising a voltage controlled oscillator (VCO) within a phase lock loop (PLL) that may be configured to generate an output signal in response to (i) a low gain control input and (ii) a high gain control input. The low gain control input and the high gain control input are generally both active.

  • Method for charge pump tri-state and power down/up sequence without disturbing the output filter
    Patent number: 6472915
    Abstract: An apparatus comprising a phase lock loop (PLL) and a charge pump. The PLL may be configured to generate an output signal in response to an input signal. The charge pump may be configured within the PLL and be configured to (i) pump-up the input signal, (ii) pump-down the input signal or (iii) enter tri-state in response to a control signal.

  • METHOD AND APPARATUS FOR EVALUATING SWIMWEAR FOR UNDERWATER LEAKAGE
    Publication number: 20020121128
    Abstract: A quantitative method of evaluating swimwear for underwater leakage using a mechanical test mannequin, a water tank, a fluorescent bowel movement simulant, and a fluorescence meter. More particularly, a swimwear garment is applied to the mannequin, the fluorescent bowel movement simulant is inserted into the swimwear garment, the mannequin and the swimwear garment are submersed into water within the water tank, and a motion mechanism attached to the mannequin moves the mannequin up and down, thereby simulating typical water play movements. The fluorescence meter can be used to quantitatively determine the amount of leakage of the fluorescent bowel movement simulant from the swimwear garment.

  • Methodology for mapping use cases to operations for operational profile development
    Patent number: 6385763
    Abstract: A method and apparatus for mapping use cases to an operational profiles. Initiators of operations in the operational profile may be identified from the actors of the use case model. A list of operations for the operational profile is created from the use cases of the use case model. Occurrence rates corresponding to the operations on the list of operations are obtained. Based on the occurrence rates of all the operations considered, the occurrence probabilities of the operations are calculated.

  • Low supply voltage BICMOS self-biased bandgap reference using a current summing architecture
    Patent number: 6181121
    Abstract: An apparatus comprising a first circuit, a second circuit and a third circuit. The first circuit may be configured to generate a first current in response to a reference voltage. The first current may vary as a function of temperature. The second circuit may be configured to generate a second current to counteract for the variations of the first current. The second current may vary as a function of temperature. The third circuit may be configured to generate a third current in response to the first current and the second current.
