  • Water caloric systems and methods for inducing nystagmus
    Patent number: 4023561
    Abstract: Systems and methods for delivering waters at different temperatures to the patient's ears to induce nystagmus. The systems use compressed air to deliver water at a specified temperature to the selected ear of the patient. The system vis-a-vis pump systems is quieter, thermally more efficient and diagnostically improves the entire nystagmus process.

  • Standby power supply system
    Patent number: 3991319
    Abstract: A standby power supply system utilized for continuously supplying alternating current power at a regulated value to a load independent of the line power amplitude of continuity. The standby power supply includes an inverter utilizing a direct current source. Direct current feedback circuitry is provided for improving the AC - DC synchronization, minimizing the drain on the source and for holding the direct current relatively constant thereby reducing the requirements of the direct current source.

  • Electrode switching adapter for vertical recording of electronystagmographs
    Patent number: 3946723
    Abstract: A switching adapter that provides a rapid and convenient apparatus for selective recording of vertical eye movements with a single channel recorder in electronystagmograph apparatus. A number of single channel recorders are used in the field to observe the horizontal eye movements elicited by thermally induced vestibular unbalance. In certain types of pathological unbalances, vertical eye movement is also present, therefore, it is highly desirable to be able to also record the vertical eye movement. The switching adapter conveniently converts single channel recorders that are normally used for recording horizontal eye movement for recording vertical nystagmus.

  • Air caloric stimulation system
    Patent number: 3942515
    Abstract: The air caloric stimulation system provides an adjustable air system with accurate and automatic control of the delivery and temperature of air. A thermal electric device utilizing the Peltier effect generates or absorbs heat depending on the difference between the temperature of the air at the outlet and the "set" or desired temperature of the air at the outlet. Further, the Peltier units are aided in controlling the temperature of the air using a radiator system in conjunction with a liquid circulating system. The current to the Peltier units are controlled using unique proportional phase controlled signals. Safety circuitry prevents the air or liquid from overheating.
