  • Publication number: 20200030600
    Abstract: An implantable medical electrical lead includes an electrode assembly in which an electrical junction between a first conductor and an inner surface of a first electrode of the assembly is wedged within a first channel of at least one core member of the assembly, around which the first electrode extends. The at least one core member is formed from an insulating material, and the first channel may be one of a plurality of longitudinally extending channels arrayed around a circumference of a central lumen of the assembly, which is defined by the at least one core member. The first conductor extends along a length of the assembly, for example, defined between the first electrode and a second electrode thereof, in a helical path that travels around the central lumen.

  • Patent number: 4701712
    Abstract: A thermoregulated magnetic susceptibility sensor assembly for well-logging or the like is disclosed. The assembly includes a sensing solenoid and a non-metallic container for the sensing solenoid. Located in the container and spaced from the sensing solenoid are a plurality of heaters. These heaters are uniformly positioned about the sensing solenoid and a heat transfer material is located between the heaters and the sensing solenoid. The heat transfer material conducts the heat from the heaters to the sensing solenoid in a substantially uniform manner so that the sensing solenoid is maintained at a uniform temperature. Preferably, temperature sensors are provided to control the heat output of the heaters to maintain the sensing solenoid at the desired uniform temperature. To minimize heat transfer to the heaters from the external environment, a layer of insulation is provided around the heaters.

  • Patent number: 4551681
    Abstract: The magnetic susceptibility well-logging unit with single power supply thermoregulation system provides power from a single surface power supply over a well-logging cable to an integrated circuit voltage regulator system downhole. This voltage regulator system supplies regulated voltages to a temperature control system and also to a Maxwell bridge sensing unit which includes the solenoid of a magnetic susceptibility probe. The temperature control system is provided with power from the voltage regulator system and operates to permit one of several predetermined temperatures to be chosen, and then operates to maintain the solenoid of a magnetic susceptibility probe at this chosen temperature. The temperature control system responds to a temperature sensor mounted upon the probe solenoid to cause resistance heaters concentrically spaced from the probe solenoid to maintain the chosen temperature.

  • Patent number: 4132226
    Abstract: The broadband auditory thresholds of marine mammals are determined by an apparatus which compensates for the animals' movement artifact. A number of evoked responses to audio stimuli are average during discrete time intervals. This approach reduces the effects of potentials attributed to movements of the animal, for example, the opening and closing of the blow hole. A threshold detector circuit, a tape delay and related circuitry electronically cooperate to block potentials attributed to the movement artifact when the potentials exceed the likely magnitude of the evoked response. Optionally, an oscilloscope is used to provide a visual representation of the evoked response and the potentials are manually inhibited when the movement artifact masks or otherwise overrides the evoked response.

  • Patent number: 3976962
    Abstract: An improved dual threshold switch is actuated by magnetic fields in the sch's proximity. An elongate glass envelope contains a pair of reed contacts. The contacts are biased by a piece of donut-shaped magnetic material circumscribing the envelope to be switched to a closed position at one magnetic threshold or an open position at another magnetic threshold. Both magnetic thresholds are induced in the contacts by external actuating magnets and the thresholds can be changed by physically moving the donut along the elongate glass envelope. A coil is provided and encompasses the envelope and magnetic donut to provide an electro-magnetic field which shifts the biasing field induced by the donut. When the electro-magnetic shifting field is turned on the thresholds established by the biasing field are shifted so that the contacts would be actuated from external actuation fields at different magnetic thresholds.

  • Patent number: 3967224
    Abstract: A small reed switch having a glass tubularly shaped envelope containing a ir of reed contacts is modified to ensure its being biased to either an open or a closed position. A donut-shaped piece of a rubber-bonded, barium-ferrite, magnetic material is circumferentially mounted on the reed switch at a position where its magnetic field influences the contacts to an open position or a closed position. Thusly arranged, an actuating magnet, having a sufficient field at a single pre-established distance from the contacts, actuates the switch from all radial directions from the switch. Potting the modified switch in an epoxy resin further ensures a greater reliability and makes it ideal for implantations in laboratory animals.
