Abstract
Abstract A device for repelling animals is disclosed which is adapted for use with refuse and garbage containers to discourage entry therein by foraging animals. The device comprises: (a) a detector for remote-sensing the presence of an animal within its vicinity; (b) an ultrasonic sound generator for producing an animal-repelling ultrasonic sound wave; and (c) means for temporarily activating the ultrasonic sound generator when the detector has sensed the presence of an animal within its vicinity.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
123 words
In a refuse container of the type which includes a receptacle and a lid removably fitted to the receptacle, a device carried in the container and operable for repelling animals present in the vicinity of the container location, the device comprising as components embodied in the lid (a) a detector for remote-sensing infra-red radiation emitted by an animal present within its infra-red radiation sensing range, said detector including a plurality of detecting elements received in the lid at the circumference thereof and disposed in spaced array about said circumference; (b) ultrasonic sound generator means for producing an animal-repelling ultrasonic soundwave; and (c) means for temporarily activating the ultrasonic sound generator when presence of an animal is sensed by any of the detecting elements.
Claim 2
Dependent Claim
123 words
In a refuse container of the type which includes a receptacle and a lid removably fitted to the receptacle, a device carried in the container and operable for repelling animals present in the vicinity of the container location, the device comprising as components embodied in the lid (a) a detector for remote-sensing infra-red radiation emitted by an animal present within its infra-red radiation sensing range, said detector including a plurality of detecting elements received in the lid at the circumference thereof and disposed in spaced array about said circumference; (b) ultrasonic sound generator means for producing an animal-repelling ultrasonic soundwave; and (c) means for temporarily activating the ultrasonic sound generator when presence of an animal is sensed by any of the detecting elements.
Claim 3
Dependent Claim
58 words
The refuse container of claim 1, in which the sound generator means comprises a plurality of ultrasonic sound generators arrayed in like correspondence with the plurality of detecting elements, each detecting element being connected to a corresponding sound generator whereby the output from an activated sound generator is in the direction from which animal emitted radiation was detected.
Claim 4
Dependent Claim
34 words
The refuse container of claim 1, in which the container lid has a circular circumferential rim, the detecting elements being recessed in the rim and configured with curvature to complement that of said rim.
Claim 5
Dependent Claim
39 words
The refuse container of claim 1, which further comprises a secondary detector for detecting disturbance of said container by one of tilt thereof and lid removal therefrom, said secondary detector being operable to temporarily activate the ultrasonic sound generator.
