Claims
- 1. In a recording system having a dictate station, a recorder for recording dictation, and operating means operable by said dictate station for the recording of dictation by said recorder; the improvement of
- identification means associated with said dictate station for providing a selected sequence of identification signals;
- memory means for providing at least one predetermined sequence of identification signals;
- inhibiting means responsive to said predetermined sequence of identification signals and said selected sequence of identification signals for rendering said operating means inoperable by said dictate station when said selected sequence of identification signals does not have a predetermined relationship to said predetermined sequence of identification signals,
- said inhibiting means comprising a comparator for comparing each individual signal of said selected sequence of identification signals with an individual signal of said predetermined sequence of identification signals and for providing an inhibiting output signal which renders said inhibiting means operative when an individual signal of said selected sequence of identification signals does not have a predetermined relationship to a particular individual signal of said predetermined sequence of identification signals;
- latching means responsive to said inhibiting output signal from said comparator for maintaining said inhibiting output signal independently of said comparator; and
- reset means associated with said latching means for resetting said latching means upon each occurrence of a predetermined error signal from said dictate station and upon each occurrence of a seizure condition.
- 2. Apparatus as recited in claim 1 wherein said selected sequence of identification signals and said predetermined sequence of identification signals comprise digital signals; and said comparator is a digital comparator.
- 3. Apparatus as recited in claim 1 wherein said inhibiting means is rendered inoperative in response to a correct number output, wherein said comparator is a first comparator, and further comprising
- a second comparator responsive to said selected sequence of identification signals for providing a correct number output signal only in response to detection of a predetermined number of said identification signals in said selected sequence of identification signals.
