摘要： A wireless transmitter associated with a switched electrical connection and a receiver therefor, adapted for connection in an electrical path between the source of power and a load, enables the load to be controlled by the switch originally used to control the switched electrical connection. The communication between the transmitter and receiver may be realized only when power is applied or removed from the switched connection, or, alternatively, this communication may be carried out on a per-cycle basis, enabling a phase-delay type of control over the relocated load, including dimming of the relocated load without requiring modification to a previously installed dimmer switch. The signal radiated by the transmitter may be of acoustic or electromagnetic origin, though IR transmissions are used in the preferred embodiment. The transmitter module includes means for making electrical contact to a switched electrical connection, and means for transmitting a wireless signal in response to the application of electrical Dower to the switched electrical connection, and the receiver module includes means for making electrical contact to a source of electrical power, means for making contact to an electrical load, and means for routing electrical power from the source to the load in response to the signal transmitted by the transmitter module. Exposed wires, plug- and socket-type connections may be utilized as alternatives depending upon physical implementation.

摘要： A continuous wave ultrasonic tracking system using an ultrasonic transmitter acoustically radiating a continuous wave ultrasonic transmitted signal and an ultrasonic receiver detecting the transmitted signal as a received signal. The system mixes the transmitted and received signals to create an interference pattern characterized by interference fringes, counts the number of the fringes by which the pattern changes with respect to a fixed point and stores the number as a number of wavelengths of the displacement between the transmitter and receiver, interpolates a location of the fixed point between successive ones of the interference fringes as a fraction of a wavelength and stores the fraction of a wavelength and computing the displacement by combining the number of wavelengths and the fractional number of wavelengths.

摘要： An ultrasonic detector of the type for determining the level of a liquid within a tank or the magnitude of the flow of liquid within a conduit. The detector includes a transducer that generates bursts of ultrasonic energy and receives echoes of the energy bursts. The frequency at which she transducer transmits energy bursts is automatically adjusted to substantially match the ringdown frequency of the transducer. The detector distinguishes between true echo signals and spurious echo signals by determining whether the frequency of the echo signals generated by the transducer substantially matches the frequency at which the corresponding energy bursts were transmitted.

摘要： In an acoustic pulse-echo ranging system, a high impedance piezoelectric transducer element is connected via a transformer to a transmitter, and also directly to a high impedance input of a receiver through a network, in parallel with the transducer element which includes a limiting resistor having a value which is low compared with the impedance of the transducer and a pair of oppositely connected diodes connected across the receiver input, the diodes being in series with the resistor and conducting to complete a damping circuit for large amplitude signals during transmission, and to limit the amplitude of signals applied to the receiver. When the signals are not of sufficient amplitude to cause the diodes to conduct, the damping circuit is normally rendered ineffective, but a further circuit is provided in parallel with the diodes to selectively switch into the network a further smaller resistance which acts both to form an attenuator at the receiver input in conjunction with the damping resistor, and to restore the damping effect. By this means, the dynamic range required by the receiver is much reduced, and effective damping can be applied selectively during reception to reduce the effect of ringing at short ranges. A tuned circuit formed with the transducer by the transformer through which the transmitter drives the transducer is tuned by means of an air gap in the transformer core, which may be adjustable.

摘要： An ultrasonic unipolar pulse/echo instrument uses active switches and a timing and drive circuitry to control electrical energy to a transducer, the discharging of the transducer, and the opening of an electrical pathway to the receiving circuitry for the returning echoes. The active switches utilize MOSFET devices along with decoupling circuitry to insure the preservation of the unipolar nature of the pulses, insure fast transition times, and maintain broad band width and time resolution. A housing contains the various circuitry and switches and allows connection to a power supply and a movable ultrasonic transducer. The circuitry maintains low impedance input to the transducer during transmitting cycles, and high impedance between the transducer and the receiving circuit during receive cycles to maintain the unipolar pulse shape. A unipolar pulse is valuable for nondestructive evaluation, a prime use for the present instrument.

摘要： Linear and switching amplifiers associated with acoustic transducers requ a gradual turn-on rather than an abrupt full-power level signal. A transducer preamplifier power controller circuit prevents the operation of fuses and the tripping of circuit breakers when the relatively high power driving levels for a sonar transducer are initiated. The controller circuit gradually increases a signal level from a zero level to a maximum during the initiation of a sonar signal using a threshold level that is set to a fraction of the expected maximum, and two discrete clock frequencies, for example at 1 MHz and 2 KHz actuate interconnected digital control elements incrementally to increase the signal level during a predetermined period. This cycle is re-initiated by the next sonar signal.
