Abstract
An auto-control bird-expelling device which functions independently and performs or suspends a bird-expelling operation in response to environmental change is disclosed. The bird-expelling device includes a detector and a bird-expelling signal generator. The detector automatically detects the environmental change, and informs of the bird-expelling signal generator to perform an bird-expelling operation when necessary. The environmental change can be the intrusion of birds into a designated range, and alternatively or additionally, can be the day and night change. On the other hand, the bird-expelling signal can be the sound of a fierce bird such as a hawk or an eagle, or any other visual or audio signals to drive the intruding birds away.
Claims10
An auto-control bird-expelling device, comprising:
- a detector for generating a triggering signal in response to the entrance of a bird into a specified region;
- a bird-expelling signal generator electrically connected to said detector for generating a bird-expelling signal in response to said triggering signal, thereby driving said bird away;
- a switch electrically connected to said bird-expelling signal generator for providing a user to optionally disable said detector, and said bird-expelling signal generator generates said bird-expelling signal at a predetermined interval when said detector is disabled;
- and
- a time-interval adjuster electrically connected to said bird-expelling signal generator for providing a user to optionally adjust said predetermined interval.
An auto-control bird-expelling device, comprising:
- a bird-expelling signal generator for generating a bird-expelling signal to drive a bird away;
- a first photo-sensing device electrically connected to said bird-expelling signal generator for generating a disabling signal to disable said bird-expelling signal generator when an intensity of the environmental light is lower than a threshold value;
- a controller electrically connected to said bird-expelling signal generator to have said bird-expelling signal generator generate said bird-expelling signal at a predetermined interval;
- and
- a time-interval adjuster electrically connected to said bird-expelling signal generator for providing a user to optionally adjust said predetermined interval.
