  • Patent number: 5644616
    Abstract: Subsurface regions of an X-ray transparent but optically opaque object (60) are targeted along a visible line of sight (42) obtained by the use of two radiation sources (an X-ray (46) and light beam source, preferably a laser (6)). The central ray from the X-ray source and the light beam are aligned using a calibration fixture (15), one to the other and both with respect to structures (59) internal to the object being imaged to provide the visible line of sight. The system, method and apparatus may be used in surgical applications for selective illumination and sighting to reach specific subsurface members of a patients anatomy by guiding an incision.

  • Patent number: 5642247
    Abstract: An automatic fault monitoring system prevents the detection of fault conditions during operating modes or conditions that can produce false fault conditions. A motor control system that utilizes an H-bridge circuit having active devices, preferably field effect transistors, in each arm of the bridge. The motor is connected in the leg of the bridge. Currents and voltages are sensed in each arm as different operating conditions represented by input control signals, which may be computer generated, drive the bridge and place the transistors in different states (on or off). Such operating conditions include rotation of the motor in opposite directions and reversal of direction. Fault detection logic is responsive to currents and voltages in the arms and leg of the bridge and provides outputs indicative of over-current fault conditions in the arm and open circuit fault conditions in the leg.

  • Patent number: 5634340
    Abstract: One aspect of the present invention relates to a process of cogeneration utilizing a compressed gas energy storage system which includes a gas storage area, a compression train for pressurizing a gas to be stored in the gas storage area, and an expansion train for depressurizing high pressure gas released from the gas storage area. The process includes operating the compression train during off-peak electricity utilization periods to produce a compressed gas. The compressed gas is stored in the gas storage area and later released during peak electricity utilization periods through the expansion train to generate electricity. This reduces the compressed gas pressure and temperature. The gas can then be used for refrigeration by contacting it with a material to be chilled with that gas. One aspect of this invention involves generating electricity and effecting refrigeration by depressurization of natural gas from high pipeline transmission pressures to lower distribution pressures.

  • Patent number: 5624817
    Abstract: The subject invention provides purified polypeptides encoded by naturally-occurring wild-type platelet glycoprotein Ib alpha having a mutation which renders the polypeptide more reactive with yon Willebrand factor. Preferably, the mutation is in the hinge region of GP Ib.alpha., such as the substitution of valine for glycine at residue 233. These mutations alter the three-dimensional structure of the mutant polypeptide from a beta bend conformation to an alpha helix formation, and also create an amphipathic region within the mutant polypeptide. DNA encoding the mutant polypeptides, as well as expression systems for the production of the mutant polypeptides, are also provided. Methods and compositions using the mutant polypeptides and DNA oligomers complementary to the mutant polypeptides are further provided.
