Claim 7
Dependent Claim
40 words
Alerting device according to claim 1 wherein said time interval measuring means includes a binary counter for generating a prescribed number of output pulses constituting said time interval measuring cycle, and clock means coupled to said counter for control thereof.
Claim 8
Dependent Claim
40 words
Alerting device according to claim 6 including an alert signal generator for providing an alert signal to a user in response to said alerting signal, and means coupling said output pulses as said alerting signal to said alert signal generator.
Claim 9
Dependent Claim
34 words
Alerting device according to claim 6 wherein said reset means when operated in said reset state terminates an operation of said binary counter prior to the production of said prescribed number of output pulses.
Claim 10
Dependent Claim
107 words
An altering device responsive to a calling signal for providing calling information to a user comprising, in combination, means responsive to the calling signal to provide an alerting signal during a predetermined time interval, memory means for storing said calling information, means responsive to said calling signal to set said memory means into an information-storage state, means operable within said time interval to terminate the alerting signal and the information storage state of the memory means, said means operable after the end of said time interval, in the absence of operation of said means within said time interval, to recall said calling information from said memory means.
