Patent number: 8729875Abstract: A method and circuit for controlling the delivery of power having a current component to a load having an inductive component, the method comprising selectively switching power to the load with a switch, wherein the switch is caused to operate at the threshold of saturation during a conduction state such that the switch self commutates to its off state when the magnitude of the current through the load is substantially zero. The method and circuit may be used in a number of applications for detecting a current zero crossing and may be applied to circuits such as dimmer circuits.Type: GrantFiled: December 12, 2006Date of Patent: May 20, 2014Assignee: Clipsal Australia Pty LtdInventor: James Robert Vanderzon

Patent number: 8698466Abstract: Disclosed is an inductive load detection circuit for detecting the presence of an inductive load on a dimmer circuit. The detection circuit provides for enhanced detection of the inductive load by detecting voltage ringing resulting from a turn-off of a switching element in the circuit. The ringing can be enhanced by providing a faster turn-off rate in an initial period than a turn-off rate in a steady state period. Also disclosed is a dimmer circuit comprising the inductive load detection circuit.Type: GrantFiled: September 19, 2008Date of Patent: April 15, 2014Assignee: Clipsal Australia Pty LtdInventor: James Robert Vanderzon

Patent number: 8564919Abstract: Disclosed is a method and apparatus for detecting an overcurrent condition in a dimmer circuit having two switches, each for controlling power delivered to a load, each switch having a respective anti-parallel diode. The method comprises sensing a voltage drop across one of the anti-parallel diodes, comparing the sensed voltage drop with a reference voltage, and determining that an overcurrent condition exists if the sensed voltage drop exceeds the reference voltage. Also disclosed is a dimmer circuit embodying the method.Type: GrantFiled: September 19, 2008Date of Patent: October 22, 2013Assignee: Clipsal Australia Pty LtdInventor: James Robert Vanderzon

Patent number: 8446700Abstract: Disclosed is an overcurrent protection circuit for use in a dimmer circuit having a switching device for controlling power delivered to a load. The overcurrent protection circuit comprises means for sensing a load current passing through the load and means for comparing the sensed load current with a threshold, wherein the threshold is a dynamic current threshold. Also disclosed is a dimmer circuit comprising the overcurrent protection circuit.Type: GrantFiled: September 19, 2008Date of Patent: May 21, 2013Assignee: Clipsal Australia Pty LtdInventor: James Robert Vanderzon

Patent number: 8395328Abstract: Disclosed is a method and apparatus for controlling a plurality of Light Emitting Diodes (LEDs). A communications protocol is also provided, which comprises a START code, a first Command packet and at least one subsequent Command packet. An LED driver receives a signal according to the protocol, and separates the first Command packet from the signal and controls an LED associated with the LED driver in accordance with instructions in the first Command packet. The LED driver then outputs the remaining signal for use by one or more subsequent LED drivers.Type: GrantFiled: November 5, 2007Date of Patent: March 12, 2013Assignee: Clipsal Australia PTY LtdInventors: Ashleigh Glen Quick, Andrew Newman

Patent number: 8085160Abstract: Disclosed is a circuit for detecting the presence of an inductive load. The circuit uses a voltage ringing detector to detect a voltage ringing signal across the inductive load and a signal generator for generating a signal indicating the presence of the inductive load upon detection of the ringing signal. The circuit may be used in a dimmer circuit for controlling the load. The circuit may be used as a load detector for a universal dimmer or may be used in a protection circuit for circuits not designed to control inductive loads.Type: GrantFiled: December 12, 2006Date of Patent: December 27, 2011Assignee: Clipsal Australia Pty LtdInventor: James Robert Vanderzon

Publication number: 20110194476Abstract: Disclosed are a method, system and apparatus for use in a network of devices which can facilitate the installation of the network. In a network consisting of multiple devices, it is often necessary to use repeaters to relay communications between two or more devices that are out of range of each other. The various aspects of the present invention provide for one or more of the devices to be selectively switched to operate as a repeater.Type: ApplicationFiled: February 6, 2008Publication date: August 11, 2011Applicant: CLIPSAL AUSTRALIA PTY LTDInventors: Jason Gerard, Ashleigh Glen Quick

Publication number: 20090096384Abstract: Disclosed is a universal dimmer which detects the type of load it is connected to each time the universal dimmer is activated. Information relating to the type of load connected to the universal dimmer is therefore not required to be stored for future use. In one form, the universal dimmer begins each operation in the trailing edge mode and upon detection of an inductive load, switches to leading edge mode.Type: ApplicationFiled: December 12, 2006Publication date: April 16, 2009Applicant: CLIPSAL AUSTRALIA PTY LTDInventor: James Robert Vanderzon
