Patent number: 8231240Abstract: Surface lighting devices including at least one light source, at least one energy storage device, and a thermoelectric power generation unit electrically coupled to the at least one energy storage device are disclosed herein. The at least one energy storage device is charged by the thermoelectric power generation unit, and the stored energy is used to illuminate the at least one light source. The surface lighting devices include a voltage step-up circuit that converts a DC voltage produced by the thermoelectric power generation unit into a higher-level DC voltage. Methods for illuminating a surface utilizing the surface lighting devices are also disclosed.Type: GrantFiled: December 12, 2008Date of Patent: July 31, 2012Assignee: TXL Group, Inc.Inventors: Edward Rubio, Stanley S. Hirsh, David C. Nemir

Publication number: 20040136125Abstract: An apparatus and method for detecting and interrupting electrical current leakages from the conductors in an electrical distribution system with a particular application to appliance power cords. Parallel conductive paths connect between the source and the load. Electrical current to one side of the load is furnished by these split paths with the other side of the load connecting to the source through a single conductive path. By sensing the imbalances in the split conductive paths, leakage currents that are undesirable and might lead to parallel arcing faults may be detected. By adding an additional sense line for the single conductor, complete series arc fault detection may also be accomplished. In some embodiments, two split conductors are used to supply power from source to load in one direction and two split conductors are use to supply power from source to load in a return direction.Type: ApplicationFiled: May 5, 2003Publication date: July 15, 2004Inventors: David C. Nemir, Stanley S. Hirsh

Patent number: 6560079Abstract: A low cost, low parts count electronic circuit that is built into an appliance automatically and continuously checks for an open ground condition or a condition where the power conductors are transposed, at which time, power is interrupted in the appliance. By combining this with an electrical leakage detection circuit and power interrupter at the plug, the electrical safety of the appliance is greatly enhanced.Type: GrantFiled: September 13, 1999Date of Patent: May 6, 2003Assignee: X-L SynergyInventors: Stanley S. Hirsh, David C. Nemir

Patent number: 6262871Abstract: An electronic test circuit for the self-testing of fault detection devices such as GFCI's, AFCI's and RCD's enhances the safety of such devices by automatically testing the function of all components of these detection components without the need for manual intervention. This self-test device tests the functioning of the primary circuit breaker and detects failure modes such as welded contacts in the circuit breaker. By using a secondary, “one-shot” circuit breaker, power may be safely and automatically removed from a malfunctioning fault detection device.Type: GrantFiled: May 27, 1999Date of Patent: July 17, 2001Assignee: X-L Synergy, LLCInventors: David C. Nemir, Stanley S. Hirsh, Edward Rubio

Patent number: 5973896Abstract: An apparatus and method for electrical shock protection and electrical arc fault protection in an electrical distribution system. The invention consists of a current interrupting circuit that impedes electrical current flow during short time intervals in each half cycle of an AC source. If a shock hazard or electrical arc fault condition occurs during this short time interval, it results in current flow that is sensed at a load center, causing a circuit interrupter to open and preventing current flow to the distribution system for a period of time as short as one half cycle. When the fault is removed, that event is detected within one half cycle and power is restored to the load thus implementing an automatic reset. The invention is well suited for the retrofit of existing electrical distribution systems using the existing wiring.Type: GrantFiled: November 26, 1996Date of Patent: October 26, 1999Assignee: David C. NemirInventors: Stanley S. Hirsh, David C. Nemir

Patent number: 5943198Abstract: A circuit for the avoidance of electrical shock and burns in an electrical appliance. Designed primarily for a two wire appliance, the device consists of a conditioning circuit at the load and a fault sensor/interrupter at the plug. The conditioning circuit halts the flow of current to the load for a portion of each cycle of an AC excitation. If current flow is detected at the plug during this time interval it is indicative of a fault condition and a circuit breaker at the plug is opened. A fault is detected if one of the following conditions occurs: 1) a resistive path is established between hot to ground; 2) a load other than the conditioned load is placed between hot and neutral; and 3) an overtemperature condition is detected at the load. The circuit is self-resetting so that in the absence of a hot to ground fault, hot to neutral fault, or overtemperature condition, electrical current is allowed to flow.Type: GrantFiled: February 13, 1997Date of Patent: August 24, 1999Assignee: David C. NemirInventors: Stanley S. Hirsh, David C. Nemir

Patent number: 5844759Abstract: An apparatus and method for the avoidance of electrical shock in an electrical appliance. Preferred for a two wire appliance, the device consists of a current interrupting circuit that impedes current flow for short time intervals in each half cycle. If a fault to ground occurs during these short time intervals, an increased current flow through the plug is detected and this is recognized as a fault, causing a circuit interrupter to open and removing current from the load during the remainder of the half cycle. When the fault is removed, that event is detected within one half cycle and power is restored to the load. The apparatus can provide thermal control in the plug. The apparatus enables the use of a low current, low voltage switch to control high voltages and high currents in the appliance. The apparatus can transmit fault status information or other information to a remotely located controller and can receive control signals from that remotely located controller.Type: GrantFiled: May 22, 1996Date of Patent: December 1, 1998Assignee: David C.
