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.
Claims4
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.
