Abstract: An apparatus comprises a mask, a sensor body configured to be attached to the mask, and an electronic module for producing an output in response to air flow through the sensor body.

Abstract: A radiation detector includes a new and sensitive radiation sensor. The sensor includes a photo conductor cell. A substantially transparent cone optically coupled to the photo conductor cell, and a first layer of phosphor material coated onto the transparent cone. The layer of metal is then coated onto the phosphor material. This combination provides a sensitive and compact sensor construction. A bias light is further included to improve the sensitivity of the sensor. Signals sent by the sensor and evaluated by a microprocessor result in the transmission of predetermined audible sounds.

Abstract: A ventilatory support system which controls the flow of breathing gas to a patient based on the physiological requirements of the patient is disclosed. Gas pressure in the trachea of the patient is measured, and the delivery of breathing gas to the patient is controlled based on the sensed gas pressure. Depending on the physiological needs of the patient, a tracheal gas pressure limit and a breathing gas flow rate value are established. When the tracheal gas pressure limit is reached, the flow of breathing gas is reduced or terminated. The flow of breathing gas is resumed, for example, after a delay period, or after the tracheal gas pressure falls to a predetermined level.

Abstract: An electrical clamp connector with first and second half portions connected together and providing at least two mating grooves for electrical conductors to be electrically bridged. Bridging plates extend transverse to the grooves in one half portion and oppose corresponding bridging plates in the other half portion. Each bridging plate has first and second sets of piercing teeth to pierce the conductors at the grooves. The second half portion has substantially greater depth than the first half portion. Improved high real torque connecting means are provided by a bolt, a threaded upstanding tubular pipe in the second half portion, a first threaded cylindrical passage underlying the tubular pipe, a flat or curved metal plate with a threaded passage and encapsulated in the second half portion substantially above the bottom of the second half portion, and a second cylindrical passage below the metal plate.

Abstract: Fully insulated clamp connectors for electrically joining insulated wires include molded top and bottom insulating halves bolted together, longitudinal mating grooves in each half for the insulated wires, bridging plates with insulation piercing teeth inserted in slots in each half with the teeth protruding at the grooves, the bridging plates having ramps to lock into the slot sides to prevent removal for safety reasons, and the slots having aligning ridges for the bridging plates. The bridging plates are spaced a distance to maximize the number of strands of insulated wire contacted by the teeth in the connector. Side male-female loosely interfitting parts are on opposite connector halves and dimensioned to allow a degree of rocking of one half with respect to the other to accommodate various sizes of conductors while maintaining full side insulation and long side leakage paths.
