Remote device for silent awakening

An alarm clock for silently awakening a user among a plurality of users comprising:

• an alarm time setting means operable to set a user-defined alarm time one alarm time for each of said plurality of users;
• said alarm time corresponding to a user-defined time-of-day,
• an alarm time detection means operable to produce an initial alarm signal when said alarm time detection means detects a coincidence of the present time with said user-defined alarm time set by said alarm time setting means;
• an encoder operable to produce an encrypted alarm signal when said initial alarm signal is available as an input to said encoder wherein said encrypted signal identifies said user;
• a transmitter operable to transmit said encrypted alarm signal;
• a receiving circuit operable to receive said encrypted alarm signal transmitted from said transmitter;
• a decoder operable to decrypt and authenticate said encrypted alarm signal and produce a corresponding wake-up signal;
• and
• a vibrating mechanism operable to produce a mechanical vibration upon receiving said wake-up signal, said mechanical vibration utilized to awaken said user when said vibrating mechanism is in contact with said user.

An alarm clock for silently awakening a user comprising:

• a timekeeping circuit operable to provide a time display output and an alarm signal output;
• a time display panel coupled to receive said time display output from said timekeeping circuit;
• a functional switching unit coupled to receive an alarm signal from said alarm signal output of said timekeeping circuit;
• a delayed timer coupled to receive said alarm signal from said functional switching unit when said functional switching unit is selected to provide a back-up alarm to said user;
• a cyclical alarm interrupt circuit to intermittently prevent said alarm signal presence at the output of said cyclical alarm interrupt circuit when said functional switching unit is selected to provide a cyclical alarm interrupt option;
• a device switching unit coupled to receive said alarm signal from the output of said delayed timer and the output of said cyclical alarm interrupt circuit;
• an encoder having an encoder input and an encoder output, said encoder operable to produce an encrypted alarm signal at said encoder output when said alarm signal is present at said encoder input and said device switching unit is selected to provide a silent awakening alarm for said user;
• a transmitting circuit having a transmitter input, said transmitter input coupled to said encoder output, said transmitter operable to transmit said encrypted alarm signal;
• and
• an audible back-up alarm operable to provide an acoustic alarm signal to awaken a user when said device switching unit is selected to provide a back-up awakening feature, said acoustic alarm delayed in time from the initial occurrence of said alarm signal.
