Abstract: The disclosure is directed to a transcranial Doppler probe. The transcranial Doppler probe includes a spherical bearing, a piezoelectric transducer pivotally attached to the spherical bearing, and first and second rods coupled to the piezoelectric transducer. The first rod is configured to pivot the piezoelectric transducer around a first pivot axis and the second rod is configured to pivot the piezoelectric transducer around a second pivot axis.

Abstract: The present disclosure relates to an integrated system for measuring hand strength and dexterity. Specifically, the integrated system allows for measuring of hand muscle strength through the pinch-grip test, of intrinsic hand muscle strength, and testing of performance in various dexterity tests.

Abstract: A non-polarized electronic condensate overflow switch uses microprocessor-controlled low-resistance MOSFETs to connect and disconnect power to an HVAC system. The condensate overflow switch derives operational power directly from an AC main and does not need an external power supply or a separate, reference ground line, and therefore does not require configuration in a particular polarity. The microprocessor controls the turning on and off of the power MOSFETs as needed when condensate overflow is detected and also provides more efficient sensing of condensate overflow and other operations, thus minimizing the power needed by the condensate overflow switch. Such a non-polarized electronic condensate overflow switch may be installed within a drain pan, in line with an outlet of the drain pan, or at a remote location away from the drain pan.

Abstract: An electronic housing having two speed pickup devices automatically sends electric signals to an electronic governor which causes the RPM of the steam turbine to increase, decrease or remain constant, in conjunction with software and electronic circuitry for controlling the management of a plurality of power sources for the electronics and minimizing the amounts of power used in such electronics.

Abstract: Various methods and systems are provided for finding blood vessels. In one embodiment, a method includes extracting a plurality of pulsed wave Doppler data streams, where each data stream corresponds to one of a plurality of depths; determining blood flow information for each of the plurality of depths based on the corresponding data stream, the blood flow information including flow velocity, flow direction, and amplitude of the data stream; and providing a visual display based upon the determined blood flow information, where the visual display includes the determined flow velocity, flow direction, and amplitude of the data stream corresponding to at least one of the plurality of depths.

Abstract: The invention relates to an apparatus for measuring the heart rate and the respiration rate of one or more anesthetized rodent while monitoring and maintaining body temperature of at least one or more anesthetized rodent during diagnostic or surgical procedures. The apparatus includes a printed circuit board having four electrodes, two of which are injection electrodes and two of which are sensor electrodes. The heart rate is monitored through known electrocardiogram techniques, however, the respiration rate is monitored by injecting an electrical current across the chest of the rodent between two of the electrodes to determine impedance of the electrical current across the chest of the rodent. The impedance is carried by a respiration signal that is then graphically displayed to measure and, thus, monitor the respiration rate. The apparatus further includes the ability to maintain and monitor the body temperature of the rodent.

Abstract: A method and apparatus is provided for automated control and positioning of a mandrel within a pipe during bending operations. Position detection is accomplished by means of a low frequency electromagnetic signal transmission from a coil placed in close proximity parallel to the pipe outer surface. This signal is detected by a pair of orthogonal receiving coils mounted on the mandrel in close proximity to the pipe inner surface. The phases of the received signals with respect to the transmitted signal and the ratio of the amplitudes of the two received signals is used to estimate the relative position of the transmitter and the receivers. Control of the mandrel along with transmission of reference phase information is accomplished via a high frequency direct sequence spread spectrum radio link between a computer console outside the pipe mounted on the bender and a computer unit mounted inside the pipe on the mandrel.
