  • Patent number: 10739803
    Abstract: A phase-redundant voltage regulator apparatus includes groups of regulator phases, each having a multi-phase controller (MPC) connected to each regulator phase. The MPC transfers, to control logic, phase fault signals and a pulse-width modulation (PWM) phase control signal received from each dedicated regulator phase of a phase group. Spare regulator phases include output ORing devices to limit current flow into spare regulator phase outputs. Output switching devices are configured to electrically couple spare regulator phase outputs to a common regulator output. Control logic is connected to the phase groups MPC and asserts phase enable signals to, transfers PWM phase control signals to, and receives phase fault signals from the spare regulator phases. The control logic electrically interconnects a spare regulator phase to a phase group including a failed regulator phase in response to receiving a phase fault signal from an MPC.

  • Publication number: 20110127716
    Abstract: The present invention is directed to target assembly for receiving a golf ball comprising a plurality of parallel golf ball receiving elongate channels; each channel having substantially the same width the other channels and each channel comprising a plurality of discrete golf ball receiving zones. That the channels may be adjusted and adapted to provide one or more consolidated target for players to aim for on the golf ball putting practice device. The sub-divisions of each channel and the plurality of channels form a grid structure. By assigning different scores to the different sub-divisions of each channel, one or indeed multiple targets can be formed. These targets can be then altered to prevent ‘muscle memory’ effects from assisting a player to achieve a high score.
