摘要： An impact detection apparatus (10) includes a device that utilizes multiple sensor elements (11) to determine whether or not a ball lands in or out on a tennis court (12). The sensor positions (13-134) are adjacent to the various boundary lines of the tennis court (12). The sensor elements (11) are layered devices which, when compressed, generate an electrical impulse. The impulse is then analyzed through various signal processing means so that an impact caused a sensor (11) to be compressed may be characterized as being a ball, a footstep, or some other object. In this way, near-simultaneous impacts of a ball and a footstep can be distinguished. If the impact is characterized as a ball that has landed out, a control console (206) will give a visual and/or audible signal so that players, and officials if present, are informed that the ball was out.

摘要： The present invention utilizes a latching relay having on and off inputs for controlling power to a load. The on and off inputs of the relay are controlled by pulse generators which are in turn controlled by an occupancy sensor circuit. These pulse generators provide pulses when movement is initially detected in a room and when no movement has been detected for a predetermined time, respectively. The outputs of the pulse generators are coupled to an isolation circuit which isolates the power supply for the occupancy sensor from the pulses during each pulse to prevent damage to the power supply.

摘要： An alarm system includes apparatus to be placed in a room to transmit ultrasonic wave signals that rebound off the room's walls and contents, to, and receive the rebounding signals, and to phase balance the transmitted and received signals in order to detect a subsequently unbalance condition caused by a changed in the rebounding signals due to intrusion activity, which produces an electrical alarm signal. Other circuitry responds to reception of an alarm signal to produce an audible or visible alarm. The alarm signal is typically transmitted over electrical power lines.

摘要： A microcomputer system for converting an analog signal, such as an audio or video signal representative of sound or video into a digital form for storing in digital form in a highly condensed code and for reconstructing the analog signal from the coded digital form. The system includes reductive analytic means where the original digital data stream is converted to a sequential series of spectrograms, signal amplitude histograms and waveform code tables. Approximately 100 times less storage space than previously required for the storage of digitized signals is thereby obtained. Additive synthesis logic interprets the stored codes and recreates an output digital data stream for digital to analog conversion that is nearly identical to the original analog signal.

摘要： Drift of the standing wave pattern in an acoustic doppler intrusion detection system in a confined space is compensated by adjusting the relative radiating and receiving positions of the radiator and receiver transducers, respectively, either mechanically or electrically until the signal level of the carrier wave at the receiver transducer is optimized. In the mechanical adjustment mode, either the receiver transducer or the radiating transducer is supported for movement relative to the other and is moved by a motor energized under the control of a signal level sensor circuit connected to the output of the receiver transducer. In another mode, a plurality of receiver (or alternatively radiator) transducers are connected through a switch to the signal level sensor circuit which in response to a drop in received signal level below a predetermined threshold, selectively switches the active transducer to optimize the received signal level. In still another mode, one of at least two radiator (or alternatively, receiver) transducers is connected through a variable phase shifter to the signal generator (or to the receiver circuit for the receiver transducer), the phase shifter being adjustable in response to the output of the signal level sensor to optimize the signal level at the receiver transducer. The invention comprehends the apparatus for and method of optimizing signal strength at the receiver transducer.

摘要： A motion detector system includes an ultrasonic transmitter, receiver and phase detector which produces as output signals of frequency related to the speed of movement of any moving object in a zone being monitored. The output of the phase detector is fed to two separate bandpass filters having different pass-bands characteristic of the frequencies generated by a human being moving in the zone being monitored. A warning is sounded only when signals have been present in both bands for more than a predetermined period.

摘要： A vibration sensor device is mounted on a translucent ornamental disc so it can be mounted at any desired position on a window pane so as to achieve the greatest sensitivity without being asthetically offensive. A bracket affixed to the disc mounts a base to which electrical leads are attached to connect the sensor to an alarm control unit. A motion sensing switch is detachably connected to the base to allow easy substitution of switches of different sensitivities. A cover hides the bracket, base, and switch and the whole unit is adhesively attached to the window pane.

摘要： An ultrasonic alarm device has a detector for detecting a reflected ultrasonic wave in a watching area to obtain a Doppler signal due to motion of a person, a Schmitt circuit for converting the detection output into a pulse output and a waveform shaping circuit for shaping the pulse output into a pulse train having a certain pulse width. The output of the waveform shaping circuit is fed in parallel to two band-pass digital filters, one for the Doppler signal and the other for noise signals. Each of the filters comprises two monostable multivibrators connected in parallel and an AND gate having three inputs of which one is connected through an inverter to the output of one monostable multivibrator, a second is connected to the output of the second monostable multivibrator and the third to the input of the monostable multivibrators. The output of the Doppler signal filter is fed through a first integrator to a level decision circuit while the output of the noise signal circuit is fed through a second integrator to the first integrator. The level decision circuit is connected through a third integrator to an output circuit which produces an alarm signal when the signal level is above a predetermined value. Through this circuitry, the Doppler signal due to motion of a person is distinguished from external disturbances such as those due to wind, a telephone bell, an electric click or movement of a small animal, bird or insect.
