Patent number: 7290395Abstract: A high power thermoelectric controller system is disclosed, capable of operating multiple thermoelectric cooler (TEC) devices, each with a maximum power demand greater than 200 watts. The controller system utilizes interleaved triggering of multiple pulse width modulated power conversion circuits in order to minimize switching transient currents. In another aspect, the system incorporates a novel combination of a PWM controller circuit and H-bridge switching network into a single circuit that reduces the number of components needed to provide closed-loop proportional control of multiple TEC devices in a temperature control system.Type: GrantFiled: October 6, 2005Date of Patent: November 6, 2007Assignee: GentCorp LtdInventor: Jeffrey Deal

Publication number: 20070217163Abstract: An implantable device includes a device case comprising amorphous non-ferrous metal alloy material and having lower electrical conductivity than crystalline atomic structures comprising the same alloy constituents. The generation of eddy currents is thereby reduced and inductive charging and/or telemetry system operation can take place at higher frequencies with a resulting improvement in energy and data transfer efficiency.Type: ApplicationFiled: March 15, 2006Publication date: September 20, 2007Inventors: Wilson Greatbatch, Jeffrey Deal

Patent number: 7136701Abstract: A hybrid battery power source for implantable medical use provides a generally constant low internal resistance during discharge and avoids voltage delays of the type that develop as a result of run down-induced resistance increase in Li/SVO cells. The hybrid battery power source utilizes two batteries or cells, one being a primary cell of relatively high energy density and the other being a secondary cell of relatively low internal resistance that is rechargeable. The primary and secondary cells are connected in a parallel arrangement via a voltage boost/charge control circuit that is powered by the primary cell and adapted to charge the secondary cell while limiting charge/discharge excursions thereof in a manner that optimizes its output for high energy medical device use. The energy storage capacitors of the medical device in which the hybrid battery power source is situated are driven by the secondary cell. The primary cell is used to as an energy source for recharging the secondary cell.Type: GrantFiled: December 3, 2003Date of Patent: November 14, 2006Assignee: GentCorp Ltd.Inventors: Wilson Greatbatch, Jeffrey Deal

Publication number: 20060129192Abstract: A high energy battery power source suitable for use in an implantable medical device includes an input, an output, and two or more battery modules each comprising two or more battery cells. The battery cells are of relatively low voltage and permanently configured within each battery module in an electrically parallel arrangement in order to provide a desired current discharge level needed to achieve high-energy output. A switching system configures the battery modules between a first configuration wherein the battery modules are electrically connected in parallel to each other and to the input in order to receive charging energy at the relatively low voltage, and a second configuration wherein the battery modules are electrically connected in series to each other in order to provide to the output a relatively high voltage corresponding to the number of battery modules at a current level corresponding to the number of battery cells in a single battery module.Type: ApplicationFiled: November 15, 2005Publication date: June 15, 2006Inventors: Wilson Greatbatch, Jeffrey Deal, Glenn Thomas

Publication number: 20060122657Abstract: A programmable voltage-waveform-generating battery power source for implantable medical use enables an implantable device to deliver therapeutic electrical energy with flexible control of voltage amplitude, waveform and timing. The power source includes a high-energy battery system, a waveform control system and a power amplifier that collectively provide the capability to deliver electrical therapy with varied and programmable voltage waveforms, repetition rates and timing intervals that are unachievable with high voltage energy storage capacitors as presently practiced. The high-energy battery system supplies prime power to the power amplifier, the output of which is connected to physiologic electrodes for the purpose of delivering electrical therapy. The waveform control system is programmable and supplies waveform voltage control inputs to the power amplifier.Type: ApplicationFiled: December 4, 2004Publication date: June 8, 2006Inventors: Jeffrey Deal, Glenn Thomas
