Abstract
Abstract An apparatus for remote control applications comprises a detection device which is responsive to input signals for generating countable signals. A counting device is responsive to the countable signals for generating a time signal for each countable signal and a switching signal after a set number of countable signals. A first timer is responsive to the time signal for preventing the counting device from responding to the countable signals for a first period of time. A second timer is activated by said first timer at the end of the first period of time for resetting the counting device if a countable signal is not generated during a second period of time.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
142 words
An apparatus for remote control systems, comprising: (a) detection means responsive to input signals for generating countable signals; (b) counting means responsive to said countable signals for generating a time signal for each countable signal and a switching signal after a set number of countable signals; (c) gate means connected between said detection means and said counting means; and (d) first timer means, responsive to said time signal for operating said gate means whereby said counting means is prevented from responding to said countable signals for a first period of time; (e) second timer means activated by said first timer at the end of said first period for resetting said counting means if a countable signal is not generated during a second period of time; and (f) relay means responsive to said switching signal for controlling a device connected to said apparatus.
Claim 2
Independent Claim
142 words
An apparatus for remote control systems, comprising: (a) detection means responsive to input signals for generating countable signals; (b) counting means responsive to said countable signals for generating a time signal for each countable signal and a switching signal after a set number of countable signals; (c) gate means connected between said detection means and said counting means; and (d) first timer means, responsive to said time signal for operating said gate means whereby said counting means is prevented from responding to said countable signals for a first period of time; (e) second timer means activated by said first timer at the end of said first period for resetting said counting means if a countable signal is not generated during a second period of time; and (f) relay means responsive to said switching signal for controlling a device connected to said apparatus.
Claim 3
Dependent Claim
27 words
The apparatus of claim 1 further characterized in that said detection means includes a transducer means for converting a sound input signal to an equivalent electrical signal.
Claim 4
Dependent Claim
34 words
The apparatus of claim 2 further characterized in that said detection means further includes selection means for selecting the range of frequency, volume and duration of said electrical signal to form the countable signal.
Claim 5
Dependent Claim
38 words
The apparatus of claim 1 wherein said switching signal is utilized for turning said device on after a first set number of countable signals and for turning said device off after a second set number of countable signals.
Claim 6
Dependent Claim
23 words
The apparatus of claim 4 wherein the first set number of countable signals is greater than said second set number of countable signals.
Claim 7
Dependent Claim
33 words
The apparatus of claim 1 further characterized in that said second timer means is reset in response to a time signal received by said first timer means during said second period of time.
Claim 8
Dependent Claim
19 words
The apparatus of claim 6 wherein said first period of time is less than said second period of time.
Claim 9
Dependent Claim
26 words
The apparatus of claim 1 wherein said relay includes a power switch means for turning on and controlling said device in response to said switching signal.
Claim 10
Dependent Claim
27 words
The apparatus of claim 8 further characterized in that automatic timing means are provided for turning off said power switch means and preventing said device from operating.
