Portable self-contained intrusion detector for passenger aircraft
First Claim
1. An intrusion detector for passenger aircraft, comprising:
- a portable housing adapted to be hand carried into a detection zone within the aircraft;
a battery disposed in the housing, the battery being connected to power the detector apart from connection to a power source in the aircraft;
at least one detection device including an infrared motion sensor, disposed within the housing and operative to detect activity in the detection zone; and
a control means connected to the at least one detection device, the control means also being connected to activate at least one of an indicator and a signaling means when said activity is detected, the control having a delay feature operable for at least temporarily disabling the intrusion detector such that an authorized individual can temporarily occupy the detection zone without triggering the control means.

Abstract
An intrusion detector for passenger aircraft has a portable housing including on board power means, at least one sensor operable to detect activity along a detection beam alignable to the aircraft and an indicator such as a strobe light providing a flashing-light alarm visible through the aircraft windows. The detector is self-sufficient, being carryable onto the aircraft by security personnel, and there activated without exposure to possible tampering. The sensor and/or indicator are armed after a delay allowing the security personnel to depart the detection zone, and activation of the indicator is delayed following detected activity, allowing security personnel to disarm the device by entry of a code, without indicating alarm conditions.

11. An intrusion detector for a passenger aircraft, comprising:
-
a portable housing including an internal power supply sufficient to operate the intrusion detector for a predetermined time, the housing being adapted to be hand carried onto the aircraft, the intrusion detector being self-contained and operable free of connections to the aircraft; at least one detection device including a passive infrared sensor disposed in the housing and operative to detect activity in a detection zone; an indicator operative to change state for indicating activity in the zone; and
,a control means connected to the detection device and indicator, including means operable to disable the intrusion detector for at least one of an initial delay and an activation delay, the initial delay allowing an authorized individual installing the intrusion detector to depart prior to activation thereof, the activation delay allowing an authorized individual to arrive and disable the intrusion detector, also without activating the indicator. - View Dependent Claims (12, 13, 14, 15, 16, 17)
