Abstract: A digitally controlled frequency generator is provided having a selectively variable output frequency with crystal controlled accuracy and stability. Should the desired output frequency drift, however, a phase comparator detects the drift and compares the phase thereof with a provided reference signal. The resultant error signal is then fed into the frequency generator to shift the frequency back to its original value. In addition, should it be desired to change the output frequency of the frequency generator, a new program is applied to a variable program counter which produces an electronic response representative of the new program. This response is sensed by both the phase comparator and an acquisition circuit, the acquisition circuit providing signals to the phase comparator to achieve a ''''lock-in'''' of the system at the new desired frequency.

Abstract: A switching network inhibiting the flow of current from a power supply to a load until the receipt of an actuating signal at the set terminal of a flip-flop within the switching network. The flow of current continues until the actuating signal is removed, an inhibiting signal is received at the reset terminal of the flip-flop and a predetermined fixed period of time has lapsed after receipt of the inhibiting signal.

Abstract: An adaptive acoustic detector provides a signal for switching on the power supply of approximately positioned transmitter upon the detection of desired information which may comprise either a continuous or an impulse acoustic signal, irrespective of the attendant background noise. A composite signal composed of both the desired information and background noise is separated by a background insensitive amplifier which selectively feeds back only the background information thereby allowing the unattenuated passage of the desired information. An appropriate detector, upon the receipt of the desired information, permits the passage of a signal indicative thereof to provide the above mentioned switching signal. The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor.

Abstract: A detector provides a signal for switching on the power supply of a proximately positioned transmitter upon the detection of desired information. A signal representative of the desired information is transmitted and, at predetermined times thereafter, coded signature signals are produced for transmission, these latter signals being supplied by a code generator upon the receipt thereto of pulses from a one-shot and/or repetitive interval timer. The system consumes no power in the standby mode.
