  • Patent number: 9040880
    Abstract: An electronic circuit control arrangement to sustain water discharging from an instantaneous hot water heater at a set temperature or range having a proportional water temperature signal derived from a sensing arrangement in communication with water inlet and outlet ports so as to sense the respective temperatures at each port to provide a comparatively measurable proportional difference between the inlet and outlet temperatures set against referenced parameters, including a comparator that acts as an operable control of a switch adapted to couple and de-couple an alternating current power source to the heating element through a duty cycle of highs and lows to provide a rate to generate and maintain the appropriate coupling and/or de-coupling of the alternating current power source to and from the heating element to achieve the desired referenced temperature and/or range.

  • Patent number: 8891267
    Abstract: A circuit arrangement with standby mode minimizing power and/or current consumption having a mains AC power supply terminals and an active circuit capable of converting said mains AC power to lower voltage DC levels for operating in an active mode or in a standby mode as required by an appliance such that the selection of the current sensing resistor value for said current sensing resistor limits the maximum peak current through the FET so that the current sensing resistor arrangement is capable of providing significant increases in a steeper rise time of the current at around mains AC power supply zero crossing, so that current is pulled high while the mains AC power supply voltage is low.

  • Patent number: 8872433
    Abstract: An electronic control system for operating lighting is rated and operable from normal AC mains supply voltages. A street light controller is adapted to activate a luminaire when ambient light levels are considered too dark and, conversely, when ambient light levels are sufficient, the luminaire is turned off.

  • Patent number: 7840734
    Abstract: A bus buffer can include a data buffer and a clock signal buffer. The data buffer for can include two symmetrical buffer circuits with an output signal that can follow the input voltage to provide bi-directional buffer action for a data path of the bus buffer. The clock buffer can operate in a forward or reverse direction, where the signal direction for the clock signal path in the bus buffer can be controlled with a direction input. The bus buffer can also include an enable circuit for enabling the data path and the clock signal path.
