  • Patent number: 10624246
    Abstract: A system for limiting or diminishing current to unpowered Serializer/Deserializer (SerDes) circuitry is provided. The system comprises receiver input termination circuitry and a cold spare circuitry. The receiver input circuitry comprises a termination resistor and an N-type metal oxide silicon field effect transistor (MOSFET). The cold spare circuitry comprises a first MOSFET and a second MOSFET. When the system is powered on, an input current flows to the receiver input termination circuit to be discharged by the N-type MOSFET which is electrically connected to a ground. When the system is powered off, the input current flows to the cold spare circuitry to discharge the input current. Discharging electrons between the first MOSFET and the second MOSFET depends on the polarity of an accumulated voltage.

  • Patent number: 9183332
    Abstract: A system and method for an automated way of running spice on a small portion of a design is presented. The system includes a sub-circuit netlist generation processor and an analog simulation processor. The sub-circuit netlist generation processor generates a sub-circuit netlist based, at least in part, on a HDL netlist, a parasitic capacitance database and trace rules. The sub-circuit netlist contains significantly fewer paths than the HDL netlist of an entire design so that its simulation time is much quicker. The analog simulation processor generates analog simulation results of the sub-circuit netlist based, at least in part, on dynamic inputs.

  • Publication number: 20150298595
    Abstract: A watercraft trailer device facilitates positioning of a watercraft trailer and supports a person on a watercraft trailer facilitating release of a watercraft from the watercraft trailer without having to enter a body of water. The device includes a frame having a front end, a back end and a pair of longitudinal sides extending between the front end and the back end. The frame supports a watercraft. Wheels are coupled to the frame to support the frame on a ground surface. A hitch is coupled to the front end of the frame for towing the frame with a vehicle. A support deck is coupled to the frame extending along an associated one of the longitudinal sides of the frame from the front end of the frame. In an embodiment, an extension is pivotally coupled to the frame and extendable to facilitate positioning of the frame when backing up.

  • Patent number: 8928348
    Abstract: A current-mode-logic gate designed to have a first electronic path and a second electronic path. Each electronic path has a pair of transistors. The second electronic path is physically separated and identical to the first electronic path. In operation, a first input signal is transmitted through the first electronic path of the current-mode-logic gate to produce a first output signal. Similarly, a second input signal is transmitted through the second electronic path of the current-mode-logic gate to produce a second output signal.
