Patent number: 8686668Abstract: Apparatus for maintaining at least a holding current in a leading-edge phase-cut dimmer during a period of transient voltage variations, the apparatus connectable to the dimmer and connectable to a load connected to draw current from the dimmer. The apparatus may comprise an edge detector connected to receive a voltage from the dimmer and generate a leading-edge signal in response to a leading-edge of a phase-cut waveform, and a current offset circuit connected to receive the leading-edge signal and draw a supplementary offset current in response to the leading-edge signal, wherein the supplementary offset current is sufficient to maintain at least a holding current in the dimmer during the period of transient voltage variations. The current offset circuit may comprise a holding current circuit which also draws supplementary current in response to an instantaneous value of load current.Type: GrantFiled: April 25, 2011Date of Patent: April 1, 2014Assignee: Koninklijke Philips N.V.Inventors: Miroslaw Marek Grotkowski, Milen Moussakov, Gregory Bernard Sheehan, Tom William Thornton, Thomas George Foxall

Publication number: 20130339044Abstract: Applications for risk evaluation and mitigation strategy (REMS) are disclosed herein. Such applications may execute on devices operated by healthcare professionals, patients, pharmaceutical companies, pharmacies, third parties and other parties. One or more of such devices may be mobile devices, thereby allowing information to be presented and obtained at a variety of times and locations. One or more different features may be made available to each of such parties as necessary to assist in their desired scope of interaction with a REMS program. Applications on client devices may communicate with one or more servers to send and receive information associated with REMS related features.Type: ApplicationFiled: June 14, 2013Publication date: December 19, 2013Inventors: Paul Bernard Sheehan, Christopher J. Linzer

Patent number: 8344630Abstract: Solid state light sources are compatible with AC phase-cut dimmers. The light sources may have switching mode power supplies having primary and secondary sides that are in first and second circuit parts that are electrically isolated from one another. Information regarding a waveform of input electrical power is extracted in the first circuit part and passed to a controller in the second circuit part by way of a galvanic isolator. Additional isolated paths may be provided to provide bi-directional exchange of information between the first and second circuit parts and/or to provide for the exchange of additional information relevant to control. The signal path from the first side to the second side may have a low latency.Type: GrantFiled: May 28, 2012Date of Patent: January 1, 2013Assignee: Light-Based Technologies IncorporatedInventors: Miroslaw Marek Grotkowski, Gregory Bernard Sheehan

Patent number: 8339066Abstract: Holding current circuits in light sources controlled by a dimmer are operated in a coordinated manner to maintain proper operation of the dimmer without wasting energy. A plurality of light sources each including a separate holding current circuit may be controlled by a dimmer. The holding current units are selectively disabled and/or a maximum holding current drawn by the holding current units are selectively adjusted to maintain a desired current draw.Type: GrantFiled: March 25, 2011Date of Patent: December 25, 2012Assignee: Light-Based Technologies IncorporatedInventors: Tom William Thornton, Milen Moussakov, Gregory Bernard Sheehan

Patent number: 8283875Abstract: Holding current circuits and lighting assemblies comprising same are provided. Holding current circuits may be connected to loads to ensure that the load and holding current circuit together draw at least a holding current from a dimmer when the dimmer is in conduction. A holding current circuit may comprise a controlled current source configured to selectively draw current from a dimmer. The controlled current source draws current according to a control signal based on the conduction state of the dimmer and the sum of the currents in a load and the controlled current source. The control signal is generated by a current controller configured to generate the control signal to cause the controlled current source to draw a supplementary current at least as great as the difference between the holding current and the load current when the dimmer is in conduction and the load current is less than the holding current.Type: GrantFiled: October 26, 2010Date of Patent: October 9, 2012Inventors: Miroslaw Marek Grotkowski, Milen Moussakov, Gregory Bernard Sheehan, Tom William Thornton, Thomas George Foxall
