A sensor apparatus to sense when an aircraft pilot has ejected is provided for safe actuation of a rescue locator radio. The ejection sensor apparatus (20) has a microphone (40), an accelerometer (35) and logic for determining that a pilot ejection event has occurred. The microphone (40) detects the differences in sound level (30) from normal cockpit noise to those during ejection and after deployment of a rescue chute. The accelerometer (35) detects the differences in acceleration level (25) during ejection and after deployment of a rescue chute. Pre-programmed acceptance templates (55) are compared in a digital processor (60) to ensure that ejection has occurred before a rescue radio (90) is activated. A manual turn on delay or turn off capability for the rescue radio is provided for facilitation of communications. Encrypted GPS location information and a pilot code are also included in the rescue radio transmission.

A battery compartment (12) adapted to accommodate any of several different types of batteries (30, 32, 34). The compartment (12) includes a hollow region having a length equivalent to that of one or more batteries (31, 33, 35) and includes a positive contact (65) disposed at one end thereof. The compartment also includes a cap (14) adapted to couple to an end of the compartment (12) remote from the one end. The one end includes a first contact (65) and one or more additional positive contacts (63). The additional positive contacts (63) are coupled to anodes of diodes (64) having cathodes coupled to the positive contact (65).

A high isolation microwave module includes a housing floor with mounting surfaces for placing microwave components and housing walls ending in housing wall ends coupled to and projecting from the housing floor. A lid including a lid plate and lid walls ending in lid wall ends projects from the lid plate. The lid walls extend toward the housing floor and the plurality of housing walls extend toward the lid plate but neither the lid wall ends nor the housing wall ends are coupled to the housing floor or lid plate, respectively. A plurality of cavities exist between the adjacent lid walls between the housing and the lid plate and a plurality of irises exist between immediately adjacent housing walls and corresponding lid walls. The irises and cavities act as a multi-section high pass filter to provide attenuation to a microwave signal passing through the module.
