摘要： A single test transducer or a line array of test transducers is placed above the transducers of an array under test and provided with a simulated flow noise signal. The response of all of the transducers under test is derived and stored whereupon the test transducer or line array of test transducers is moved to a subsequent position wherein the process is repeated. After all positions are indexed, the stored signals representing the outputs of all of the transducers of the array under test for all transmissions are combined and processed to derive a transducer array output signal for analysis purposes.

摘要： A transducer made up of a plurality of piezoceramic tubes arranged in end to end relationship with elastomeric material between tubes. The tubes are poled and driven axially; however, the hoop mode of operation is utilized to obtain a fan-shaped beam extremely narrow in one direction and extremely broad in the direction perpendicular thereto. A suitable backing arrangement is provided for the transducer when mounted on a support body to prevent degradation of the beam pattern.

摘要： A solid state transmit-receive switching element having multiple resonant rcuits connected in a bridge arrangement by back-to-back zener diodes. While receiving, the zener diodes have a high impedance and the bridge arrangement acts as two series tuned circuits in parallel. While transmitting, the zener diodes breakdown and the bridge arrangement appears electrically as two parallel tuned circuits in series.

摘要： The temperature of an environment is determined by measuring the acoustical response of a temperature sensitive two mode resonator placed in the environment. Two variable frequency signals are generated and applied to the resonator, and the two resonant frequencies of the resonator are determined. Frequency difference of the two frequencies is determined, and if the difference lies within a substantially uniform frequency range, the environment temperature is calculated from at least one of the frequencies. If the difference lies outside of the substantially uniform frequency range, then at least one of the two signals is spurious and no temperature calculation is made.

摘要： A dipole hydrophone which includes a radiation target for acoustic energy and a counterbalancing mass. A first multilaminar magnetostrictive arm is connected to the radiation target at its center gravity and a second multilaminar magnetostrictive arm is similarly connected to the center of gravity of the counterbalancing mass. The lower portion of each arm is slotted to define two legs, and a permanent magnet, in conjunction with the slotted structure forms a closed magnetic path for flux. Windings for sensing a change in flux are slipped over the leg portions, yielding a high gain device. The two arms are connected by a coupling member which is compliantly suspended from a support structure.

摘要： A temperature sensor arrangement which utilizes high Q temperature sensitive resonators coupled to an acoustic waveguide. Several resonators, each resonant at a different frequency, are positioned at various locations in a system to be monitored and an acoustic signal is sent down the waveguide. Reflected acoustic energy is examined for the presence of the various resonant frequencies. Since the resonant frequency of each resonator is temperature sensitive, the detected signals provide an indication of temperature at the respective various locations.

摘要： A system for weighing a vehicle in motion is disclosed. One or more piezoelectric weight sensors produce charge outputs in response to the weight of a vehicle passing over the sensors. A charge amplifier converts the sensor outputs to a voltage level. A peak voltage detector detects the peak voltage, which represents the sum of all sensor outputs. The peak voltage is then converted to a weight value using the thickness sensitivity of the piezoelectric material.

摘要： A Tonpilz transducer having head and tail masses with an interposed active transducer section. The transducer unit is positioned within a housing which has a shoulder portion upon which rests a snubber member which extends to a position just behind the head mass. The transducer is supported from the head mass by means of a thin fiberglass tube which extends from the rear of the head mass and engages a flange portion of the snubber member in the vicinity of the housing shoulder. The housing has a waterproof covering as does the head member with the covering of the head member being secured to the covering by means of a removable strap such that the transducer assembly may be disassembled for repair.

摘要： A cylindrical transducer for providing an omnidirectional beam pattern in one plane and a line radiation pattern in planes normal to the omnidirectional pattern. The cylindrical transducer active element is a radially poled piezoceramic having a surface into which a square thread is spirally cut so that only a pair of electrical leads are needed to excite the whole assembly. In one embodiment the thread is cut entirely through the thickness of the cylinder and in another embodiment it is cut partially through.

摘要： A multi-electrode probe is used to create an electrophysiological depth profile during stereotactic neurosurgery. A surgeon uses CT or MRI images to identify the general location of a target site in the brain and then inserts the multi-electrode probe into this area. Each electrode on the probe produces a signal that indicates the level of activity in a nearby neuron or cluster of neurons. A processor converts these signals into an electrophysiological depth profile indicating the level of activity detected by each of the electrodes. The surgeon identifies the precise location of the target site by watching the display to determine which electrode or group of electrodes detects the highest level of neuronal activity as the stimulus is provided.
