  • Patent number: 6797018
    Abstract: An electrochemical energy storage device includes a number of solid-state thin-film electrochemical cells which are selectively interconnected in series or parallel through use of an integrated interconnect board. The interconnect board is typically disposed within a sealed housing which also houses the electrochemical cells, and includes a first contact and a second contact respectively coupled to first and second power terminals of the energy storage device. The interconnect board advantageously provides for selective series or parallel connectivity with the electrochemical cells, irrespective of electrochemical cell position within the housing. Fuses and various electrical and electro-mechanical devices, such as bypass, equalization, and communication devices for example, may also be mounted to the interconnect board and selectively connected to the electrochemical cells.

  • Patent number: 6569559
    Abstract: An improved electrochemical generator is disclosed. The electrochemical generator includes a thin-film electrochemical cell which is maintained in a state of compression through use of an internal or an external pressure apparatus. A thermal conductor, which is connected to at least one of the positive or negative contacts of the cell, conducts current into and out of the cell and also conducts thermal energy between the cell and thermally conductive, electrically resistive material disposed on a vessel wall adjacent the conductor. The thermally conductive, electrically resistive material may include an anodized coating or a thin sheet of a plastic, mineral-based material or conductive polymer material. The thermal conductor is fabricated to include a resilient portion which expands and contracts to maintain mechanical contact between the cell and the thermally conductive material in the presence of relative movement between the cell and the wall structure.

  • Patent number: 6087036
    Abstract: An improved electrochemical energy storing device includes a number of thin-film electrochemical cells which are maintained in a state of compression through use of an internal or an external pressure apparatus. A thermal conductor, which is connected to at least one of the positive or negative contacts of each electrochemical cell, conducts current into and out of the electrochemical cells and also conducts thermal energy between the electrochemical cells and thermally conductive material disposed on a wall structure adjacent the conductors. The wall structure includes electrically resistive material, such as an anodized coating or a thin film of plastic. The thermal conductors are fabricated to include a spring mechanism which expands and contacts to maintain mechanical contact between the electrochemical cells and the thermally conductive material in the presence of relative movement between the electrochemical cells and the wall structure.

  • Patent number: 6015106
    Abstract: Apparatus controllably breaks hollow spheres stored in an enclosure. A first screen is disposed within the enclosure on a screen support. The screen has holes that are no larger in mesh size than the smallest hollow spheres. The screen support provides support to the first screen and has void areas to allow debris from broken spheres to pass through. An impeller is in contact with the first screen such that movement of the impeller across the first screen breaks the hollow spheres in contact with the first screen.

  • Patent number: 5744322
    Abstract: An apparatus for counting microorganism colonies on at least on disposable microorganism culturing medium having a substantially planar substrate. The apparatus has an imaging system for detecting colonies on the substantially planar substrate, and a holder positioning device for storing and queuing one or more holders, each adapted to support one of the substrates. The positioning device moves the holders sequentially into a predetermined position relative to the imaging system so that images can be obtained. The imaging system cooperates with a counting device for counting the colonies using information from several images provided by the imaging system taken at different times as the positioning device cycles the holders past the predetermined location to be imaged. Suitable holders, and a method of queuing and counting colonies on substrates, are also disclosed.

  • Patent number: 5663532
    Abstract: An ergonometric chestpiece for a stethoscope adapted to receive auscultatory sounds from a body and adapted to be coupled to an earpiece for a user. The chestpiece is adapted to be grasped by a thumb and at least one finger of the user. The chestpiece has a bottom surface which is generally planar and is adapted to be placed near the body for receiving the auscultatory sounds. The chestpiece has an upper portion opposite the bottom surface. The upper portion has a raised center portion defining left and right indented gripping surfaces which form recesses defined by the left and right indented gripping surfaces and by a surface generally parallel to but opposite the bottom surface. The left and right indented gripping surfaces are adapted to receive the thumb and at least one finger of the user, respectively. The indented gripping surfaces have indented impressions adapted to be easily, securely and comfortably grasped by the thumb and fingers of the user.

  • Patent number: 5433395
    Abstract: A tape cartridge having a tape supply reel contained within the cartridge housing. A tape passes through a tape guideway in the cartridge housing and is attached to the tape supply reel on one end and a tape connector on the other end. The cartridge housing contains a single interlock arm pivotally mounted for rotational movement, one end of the arm which is movable into and out of the tape path, while the other end of the arm is movable through a slot in the cartridge housing. The withdrawal of the tape connector from the guideway releases the arm so that a spring can actuate the other end of the arm outwardly into locking engagement within a notch in an external housing.

  • Patent number: 5306284
    Abstract: Surgical instruments are disclosed for manipulating selected tissue in a body cavity under visual inspection. The preferred instrument includes a probe in which a blade is positioned, wherein the probe includes a lateral aperture near its distal end. The blade can be extended outwardly from the probe along a path which is essentially perpendicular to the longitudinal axis of the probe. After the blade has been extended it can be used to effectively divide tissue. An optical system can be received in the probe for viewing through the lateral aperture in the probe.

  • Patent number: 5165083
    Abstract: A removable tape cartridge (14) for insertion into a carrier (12) in order to form a two-piece videocassette (10) comprises a housing (30) with a tape reel assembly (32) therein. The tape reel assembly (32) includes a length of tape (64) with a connector (68) at one end which, upon insertion of the cartridge (14), mates with an associated connector (16) in the carrier (12) to establish connection with a take-up reel (20). The tape reel assembly (32) is normally biased downwardly by a spring (56) and is normally constrained against rotation by an internal brake assembly (70-74) responsive to insertion of the cartridge (14) into the carrier (12). The tape connector (68) is releasably secured in proper position for mating engagement with the corresponding connector (16) by one end of an arm (78), the other end of which functions to interlock the tape cartridge (14) and carrier (12) against separation upon withdrawal of the tape.

The tape reel assembly (30) includes a length of tape (56) with a connector (64) at one end which, upon insertion of the cartridge (14), mates with an associated connector (15) in the carrier (12) to establish connection with a tape-up reel (17). The tape reel assembly (30) is supported within the housing (20) for limited floating movement between up and down positions, but is normally biased toward the down position by a hold down ring (74). A clutch (66-70) provides controlled tape slippage within the tape reel assembly (30), which is normally secured against unwinding by a brake assembly (102-116) until the cartridge (14) has been inserted into the carrier (12).
