Abstract:
A reset device comprising:a ring detector comprising a ring detector input and a ring detector output, said ring detector input being electrically connectable to a telephone line, said ring detector output being transitionable to a preselected voltage for a preselected period upon detection of a ring signal at said ring detector input, said telephone line connecting a first electronic device to a second electronic device, said second electronic device having a second device reset function associated therewith; a counter comprising a counter input, a counter output, and a counter enable function, said counter input being operatively connected to said ring detector output; a timer comprising a timer trigger and a timer output, said timer output being transitionable from a first voltage to a second voltage for a preselected period upon a voltage transition at said timer trigger, said timer output being operatively connected to said counter enable function; a comparator comprising a comparator first input, a comparator second input, and a comparator output, said comparator output being at a first comparator voltage when said comparator first input is not equal to said comparator second input, said comparator output being at a second comparator voltage when said comparator first input is equal to said comparator second input, said comparator first input being operatively connected to said counter output; a number generator operatively connected to said comparator second input; and a power controller comprising a controller input and a controller output, said controller input being operatively connected to said comparator output, said controller output being operatively connected to said second device reset function.
