20090212990APPARATUS AND METHOD FOR DETECTING AND LOCATING HIDDEN OBJECTS - An apparatus and method for detecting and locating hidden objects employs a symmetrical array of five directional antennas, including a central transmit antenna and a pair of receive antennas at each side of the transmit antenna, respectively. All of the antennas are pointed in the same general direction toward an object field of interest. The transmit antenna radiates a beam of high-frequency electromagnetic energy, and the receive antennas receive high-frequency electromagnetic energy returned by hidden objects. Each pair of receive antennas has an associated phase detector, the output of which represents the phase difference between receive antenna signals corresponding to the received electromagnetic energy. A circuit determines when the outputs of the phase detectors represent predetermined phase differences and operates indicator devices.08-27-2009

20080198063Apparatus and method using continuous-wave radiation for detecting and locating targets hidden behind a surface - Continuous-wave radiation is used to detect a target hidden behind a surface. In an embodiment, a transmitter directs a beam of continuous-wave microwave radiation from a transmitting location, and reflected radiation from the target is received at first and second receiving locations closer to the surface than the transmitting location. The transmitting and receiving locations have spatial relationships such that the phase of reflected radiation received at one receiving location is in quadrature with the phase of reflected radiation received at the other receiving location. In an embodiment, direct transmitted radiation is received at the receiving locations in quadrature.08-21-2008

20100063475DEVICES AND METHODS FOR INTERSTITIAL INJECTION OF BIOLOGIC AGENTS INTO TISSUE - Apparatus and methods for injecting biological agents into tissue. Devices are provided having elongate shafts and distal injection heads for transversely driving needles into tissue and injecting medical agents into the tissue through the needles. A longitudinal force directed along the shaft can be translated to a needle driving force transverse to the shaft. Some devices provide controllably variable needle penetration depth. Devices include mechanical needle drivers utilizing four link pantographs, rack and pinions, and drive yokes for driving a first needle bearing body toward a second tissue contacting body. Other devices include inflatable members for driving and retracting needles. Still other devices include magnets for biasing the needles in extended and/or retracted positions. The invention includes minimally invasive methods for epicardially injecting cardiocyte precursor cells into infarct myocardial tissue.03-11-2010

20100101241KINETIC ENERGY HEAT PUMP - A kinetic energy heat pump and method for separating fluids into hot and cold fractions, wherein the kinetic energy heat pump comprises a blower, a nozzle, a tube having a radial bend, a diffuser having a separating baffle and at least two outputs. To use, gas is accelerated through the nozzle. The gas then travels around a radial bend, wherein centrifugal force compresses gas toward the outside of the radial bend, thereby forming hot gas molecules, and expands gas molecules near the inside wall of the radial bend to form cold gas molecules. The hot and cold gas molecules then travel through the diffuser. The separating baffle selectively directs the amount of hot and cold gas molecules that travel through hot and cold output channels of the diffuser.04-29-2010
