Abstract: The active air sampling temperature sensor module for an infant incubator includes a housing within which a temperature sensor is located together with a fan which serves to draw air from at least a major portion of the volume in the incubator across the sensor to provide a true (average) instantaneous temperature reading to a controller of the incubator which in turn controls activation of a heating system of the incubator to maintain an optimum temperature within a decreased range of deviation.

Abstract: An infant incubator heater assembly having a heat radiator which is removably mounted, so that it can be removed for cleaning and maintenance. The heat radiator has a plurality of radially extending fins. In the removal and installation of the heat radiator, it slides along a cartridge heater with which the heat radiator is closely fitted for heat transfer. Preferably, the cartridge heater is mounted for self-alignment to accommodate the close fit between the heat radiator and the cartridge heater and prevent binding as the heat radiator is removed or installed.

Abstract: A low profile keyboard switch actuator mechanism having tactile and/or audible feel, for use in combination with a membrane switch assembly, and which includes a housing for mounting on top of the membrane switch assembly, a plunger slidably positioned in the housing, an actuator pivotally mounted within the housing, and a biasing spring. The actuator has a vertical arm and a horizontal leg. A slide member is mounted on the arm. Upper and lower stops on the arm limit the range of movement of the slide member. The spring is seated upon the horizontal leg and urges the plunger outwardly in an upper opening in the housing. Cooperating cam surfaces on the plunger and the slide member function during reciprocating movements of the plunger for attaining desired sensible results with mechanism.
