  • Patent number: 5735876
    Abstract: An implantable device for temporarily maintaining cardiac output through the use of electrical forcing fields in the event of an atrial defibrillation shock causing ventricular fibrillation. The device includes an atrial defibrillator. In the event that an atrial defibrillation shock causes a ventricular fibrillation the apparatus and method then delivers a continuous train of modest voltage pulses to force partial cardiac contractions to maintain life and consciousness until the patient can receive external defibrillation.

  • Patent number: 5731568
    Abstract: A battery heating device for delivery thermal energy to at least one vehicle battery includes a battery support plate for supporting the battery, a heatable fluid tube supported underneath the battery support plate for transferring thermal energy from heatable fluid, such as engine coolant, to the battery, and one or more electric heating pads secured to the battery support plate to transfer thermal energy to the battery. The heatable fluid tube preferably is secured to the battery support plate by a continuously distributed, thermally conductive adhesive material, to enhance heat transfer to the battery via the battery support plate. The heatable fluid tube is constructed and disposed to be a non-weight-bearing member, to reduce the likelihood of engine coolant leakage.

  • Patent number: 5730699
    Abstract: A method and apparatus for improving a frequency response of a piezoelectric input or output transducer in an implantable hearing system. Multiple input or multiple output transducers obtain optimized mechanical-to-electrical or electrical-to-mechanical frequency response. Output mechanical coupling is directly to the inner ear, or through an ossicular element such as the malleus, stapes, or incus. Input mechanical vibrations are obtained from an auditory element such as the tympanic membrane, malleus, or incus. Substantially nonidentical frequency responses are obtained such as using transducers of different dimensions, different number of transducer elements, different material properties, different mounting techniques, or different auditory elements for coupling.

  • Patent number: 5722995
    Abstract: An external defibillator including an operator interface and a high voltage circuit responsive to a controller for producing monophasic waveform defibrillation pulses and/or biphasic waveform defibrillation pulses. The controller can implement a biphasic waveform test protocol by causing the high voltage circuit to sequentially generate one or more biphasic waveform defibrillation pulses before generating monophasic waveform defibrillation pulses in response to sequential actuations of the operator interface during a patient rescue.

  • Patent number: 5720998
    Abstract: A multi-layered pizza product includes multiple dough layers and multiple ingredient layers. A cheese or other ingredient layer is disposed between a first, bottom dough layer and a second dough layer disposed in a middle portion of the pizza. The cheese layer preferably includes a blend of different cheeses and has a relatively reduced moisture content in a desired range to reduce the amount of steam produced during baking. The second dough layer preferably includes at least one vent opening to vent steam that is produced by the cheese during baking. The second dough layer supports an additional ingredient layer that includes tomato sauce, cheese, and/or other traditional pizza topping ingredients. A method of producing a baked pizza product requires only a single, continuous baking step, greatly reducing the lengthy preparation time typically required for multi-layered pizza products.

  • Patent number: 5714837
    Abstract: Vertical field emission devices are described with very small cathode to anode separations. Preferred cathodes have sharp edge emitters extending, outward perpendicular to the surface of the underlying substrate. These sharp edge emitters are produced within planar photolithography by coating sacrificial conformal walls and anisotropic etching. Microencapsulation is used to produce a sealed cavity at low pressure which includes the space between the anode and cathode. The field emission components can be adapted for the production of light emitting, field emission diodes. The individual cathode emitters can be integrated with solid state components on the substrate with each cathode being independently addressable. Arrays of closely packed light emitting, field emission diodes of the present invention are particularly suitable for use in displays. These displays would be useful for flat-panel computer displays and high definition television.

  • Patent number: 5715409
    Abstract: A universal electrical interface system connects to a small computer system interface (SCSI) bus. In a passive embodiment, a set of single-ended receivers and a set of differential receivers receive electrical signals on the SCSI bus according to the single-ended or differential protocol, respectively, when each set of receivers is enabled. In an active embodiment, a set of single-ended transceivers and a set of differential transceivers transmit and receive electrical signals on the SCSI bus according to the single-ended or differential protocol, respectively, when each set of transceivers is enabled. A control mechanism connected to both sets of receivers or transceivers automatically determines whether the SCSI bus is configured to use either the single-ended or differential parallel interface protocol and selectively enables the set of single ended receivers or transceivers, or the set of differential receivers or transceivers.
