Severinsky and Theodore Louckes on April 21, 2009. “A hybrid vehicle comprises an internal combustion engine, a traction motor, a starter motor, and a battery bank, all controlled by a microprocessor in accordance with the vehicle's instantaneous torque demands so that the engine is run only under conditions of high efficiency, typically only when the load is at least equal to 30% of the engine's maximum torque output. In some embodiments, a turbocharger may be provided, activated only when the load exceeds the engine's maximum torque output for an extended period; a two-speed transmission may further be provided, to further broaden the vehicle's load range. A hybrid brake system provides regenerative braking, with mechanical braking available in the event the battery bank is fully charged, in emergencies, or at rest; a control mechanism is provided to control the brake system to provide linear brake feel under varying circumstances.”
“Implantable system for monitoring the condition of the heart,” (U.S. Patent 7,512,438) was issued to Robert E. Fischell, along with David R. Fischell, Jonathan Harwood and Steven R. Johnson, on March 31, 2009. “A "tracker system" that includes electrical leads which are part of an implanted cardiotracker plus external equipment that includes external alarm and a physician's programmer. The tracker system is designed to monitor the degradation of a patient's cardiovascular condition from one or more causes, These causes include the rejection of a transplanted heart and/or the progression of a stenosis in a coronary artery. As one or more stenoses in a coronary artery become progressively more narrow thereby causing reduced blood flow to the heart muscle coronary circulation, the tracker system can alert the patient by either or both internal and/or external alarm to take the appropriate medical action. The physician's programmer can be used to display histograms of key heart signal parameters that are indicative of the patient's cardiovascular condition.”
“Means and methods for treating headaches,” (U.S. Patent 7,494,458) was issued to Robert E. Fischell, along with David R. Fischell and Adrian R.M. Upton, on February 24, 2009. “Disclosed is a system and method for treating headaches. The system employs a self-contained, battery operated, readily portable and easy-to-operate head-mounted magnetic depolarizer to generate a transient or time-varying high-intensity magnetic field into and around the user's head or neck. The magnetic depolarizer system can be used to depolarize the neurons of the brain and/or the trigeminal nerve. This type of neuronal depolarization has the capability for terminating migraine or other types of headaches.”
“System and method of adjusting vehicle window transmission based on high beam detection,” (U.S. Patent 7,486,428) was issued to William Fourney on February 3, 2009. “A system and method for reducing vehicle window (e.g., windshield and/or backlite) visible light transmission when high beams are detected. In certain example embodiments, a detector detects the presence of a light source above certain luminescent threshold. A controller then reduces the visible light transmission of a windshield and/or backlite via an electrochromic process and/or by using electrodes to apply a voltage across a gas-filled chamber for example. The visible light transmission is restored when the controller determines that the light source detected has dropped below the threshold luminescence or has disappeared.”
- "Micro-Optical Sensor System for Pressure, Acceleration, and Pressure Gradient Measurements," (U.S. Patent 7,428,054) was issued on September 23, 2008 to Assistant Professor Miao Yu and Professor Balakumar Balachandran. Their invention is a micro-optical fiber tip based sensor system for pressure, acceleration, and pressure gradient measurements in a wide bandwidth, the design of which allows for multiplexity of the input side of the system is based on micro-electromechanical fabrication techniques. The optical portion of the system is based on low coherence fiber-optic interferometry techniques which has a sensor Fabry-Perot interferometer and a read-out interferometer combination that allows a high dynamic range and low sensitivity to the wavelength fluctuation of the light source. A phase modulation and demodulation scheme takes advantage of the Integrated Optical Circuit phase modulator and multi-step phase-stepping algorithm for providing high frequency and real time phase signal demodulation. The system includes fiber tip based Fabry-Perot sensors each of which has a diaphragm that is used as a transducer.
- "Heat-flux Vased Emissivity/Absorptivity Measurement," (U.S. Patent 7,318,671) by Saeed Moghaddam, John Lawlor and Associate Professor Jungho Kim was issued on January 15, 2008. The invention is a mechanism and method for directly observing data from which the thermal emissivity or absorptivity of a surface can be calculated. The invention teaches the use of a substantially planar heat-flux or heat-flow sensor employing a thermopile, to measure the rate of heat dissipation from a radiating surface thermally attached to one side of the heat-flux sensor where the radiating surface is exposed to a first temperature and where the second side of the heat flux sensor is in thermal contact with a heat source at a second higher temperature.
- "Novel Configuration of Thermoelectric Coolers to High-Heat-Flux Hot Spots," (U.S. Patent 7,290,596) by Assistant Professor Bao Yang and Professor Avram Bar-Cohen was issued on November 6, 2007. The invention serves to concentrate the cooling effect of a miniaturized thermoelectric device so as to provide more efficient thermal management of localized "hot spots" on semiconductor devices."
- "Shadow Moiré Using Non-Zero Talbot Distance," (U.S. Patent 7,230,722) was issued on June 12, 2007 to Professor Bongtae Han and colleague Dr. C.W. Han of the Reliability and Failure Analysis Center of the Korea Electronics Technology Institute. Their invention copes with the limitations of shadow moire encountered in high precision in-situ warpage measurements. Using the non-zero order Talbot distances, the dynamic range of measurements is increased substantially and high measurement sensitivity becomes practical, which are critically required for the warpage measurements of high-end microelectronics devices.

- "Electromechanical Device Having a Plurality of Bundles of Fibers for Interconnecting Two Planar Surfaces," (U.S. Patent 7,220,131) by Professor Michael Pecht, Joseph A. Swift, Stanley J. Wallace and Yuliang Deng, was approved by the U.S. Patent and Trade Office on May 22, 2007. The invention allows for the formation of separable or non-separable electro-mechanical connections between one or more of the generally accepted six levels of interconnection. This can help reduce the thickness of interconnects, thus allowing redundancy and additional compliance as desired.
