Abstract
The wildlife dislodging device outputs sound signal while a frequency is changed to a different frequency stepwise, and suddenly outputs a sound signal pulse of a high frequency in changing the frequency.
Claims12
A wildlife dislodging device comprising:
- a first oscillating circuit;
- a counter that counts pulse number of an output signal of said first oscillating circuit;
- a designated value-generating circuit that designates values to be counted by said counter;
- a second oscillating circuit that changes the designated value of said designated value-generating circuit at an interval of predetermined time;
- a comparator circuit that compares the count value of said counter with the designated value of said designated value-generating circuit, and outputs a pulse signal and resets said counter when said count value reaches said designated value;
- an output circuit that amplifies the pulse signal of said comparator circuit;
- sound transforming means for transforming the pulse signal of said output circuit into sound;
- a delay circuit that delays time of transmitting the designated value of said designated value-generating circuit to said comparator circuit;
- and
- an initial value-changing circuit that changes an initial value of said counter during said delay time.
7 more elements
A method of dislodging a wildlife comprising:
- a first step of outputting a sound of a frequency that changes stepwise from a first frequency to a second frequency in a first predetermined period;
- and
- a second step of outputting a sound of a third frequency that is higher than said first frequency and said second frequency in a second predetermined period after said first predetermined period.
(canceled)
A wildlife dislodging device comprising:
- means for generating a pulse signal in which a value of sound frequency is continuously changed stepwise;
- and
- means for generating a high frequency pulse signal when the value of said sound frequency is changed.
