Electric Heating > Heating Devices > With Power Supply And Voltage Or Current Regulation Or Current Control Means > Automatic Regulating Or Control Means > Including Semiconductor Means (e.g., Transistor) Including Semiconductor Means (e.g., Transistor)Including Semiconductor Means (e.g., Transistor) patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.11/08/07 - 20070257025 - Method and apparatus for probing A probe comprises a small “consumable” probe substrate permanently mounted to a circuit-under-test. The probe substrate includes a high-fidelity signal pathway, which is inserted into a conductor of the circuit-under-test, and a high-bandwidth sensing circuit which senses the signal-under-test as it propagates along the signal pathway. The probe substrate further ... 03/29/07 - 20070068926 - Power control system and method for regulating power provided to a heating device A circuit includes a switching device for controlling a power signal to be applied to a heating device. A control circuit is configured for comparing a temperature signal, indicative of the temperature of the heating device, to a temperature setpoint to generate a gate pulse signal that controls the duration ... 03/01/07 - 20070045286 - Switching power supply and method for stopping supply of electricity when switching power supply exceeds rated capacity A switching power supply includes a sensor for detecting that the output level of the switching power supply has exceeded a rated output level, and a memory that stores data for estimating temperature change of a heat-producing component during a period in which the output level is higher than the ... 02/22/07 - 20070039946 - Electrical load control apparatus and method A control circuit for an electrical load connected to a power circuit includes a switch path having a switch and a series connected voltage generator, and a controller in signal communication with the switch. The switch path is in signal communication with the load and arranged to turn the load ... 12/28/06 - 20060289462 - Air heater unit for vehicle and air heater system for vehicle A purpose is to provide an air heater unit for a vehicle and an air heater system for a vehicle, capable of easily controlling energization to an air heater. An air heater system 200 for a vehicle includes an air heater 101 having an electrothermal heating element 120 and a ... 10/12/06 - 20060226141 - High frequency heating apparatus There is constructed a constitution such that a shunt resistor 30 is interposed in series with a portion capable of measuring an output current of a unidirectional power source portion 1 of a high frequency heating apparatus and a voltage generated at the shunt resistor 30 is outputted by a ... 10/05/06 - 20060219701 - Controller and heating wire capable of preventing generation of electromagnetic waves The present invention relates, in general, to a temperature controller and heating cable used for electric heating bedding, such as an electric blanket, electric papered floor or electric fomentation device, or warmers and, more particularly, to a controller having a safety device, which can immediately shut off the supply of ... 09/21/06 - 20060207988 - Control of a cooktop heating element A user control generates a heat level input signal responsive to a user of a cooktop heating element. Logic generates an output signal having a duty cycle corresponding to the input signal. An electromechanical device connected to apply power from a source to the heating element in response to the ... ### FreshPatents.com Support |
