摘要： An electrode layer is formed on the upper surface of a first substrate, and a processing for partially removing the substrate is carried out in order to allow the substrate to have flexibility. To the lower surface of the first substrate, a second substrate is connected. Then, by cutting the second substrate, a working body and a pedestal are formed. On the other hand, a groove is formed on a third substrate. An electrode layer is formed on the bottom surface of the groove. The third substrate is connected to the first substrate so that both the electrodes face to each other with a predetermined spacing therebetween. Finally, the first, second and third substrates are cut off every respective unit regions to form independent sensors, respectively. When an acceleration is exerted on the working body, the first substrate bends. As a result, the distance between both the electrodes changes. Thus, an acceleration exerted is detected by changes in an electrostatic capacitance between both the electrodes.

摘要： A weighing apparatus includes a SAW oscillator and a “push oscillator” to force the SAW oscillator into a desired mode of operation. A SAW temperature oscillator and a thermistor are also provided. The frequency of the “push oscillator” is made immune to temperature changes by generating it via a mixer mixing the SAW temperature oscillator with an adjustable fixed frequency oscillator. Long term stability of the SAW temperature oscillator is achieved by periodic calibration with the thermistor.

摘要： Torque in a torsion member, such as a rotating shaft, is sensed by a piezoelectric element that is attached to the torsion member. The piezoelectric element has a resonant frequency that varies with changes in the torque and is part of a transducer oscillator that produces a first signal. A reference oscillator has a similar piezoelectric element and produces a second signal having a frequency that varies in response to environmental parameters. The first and second signals are heterodyned, thereby cancelling the effects due to environmental parameters acting on both piezoelectric elements and producing a resultant signal that has a frequency which corresponds to the torque applied to the torsion member.

摘要： A device (1) for measuring the strike velocity of a game ball struck by a striking element, particularly a tennis racket (2), said device being provided directly on the racket. The device comprises at least one measuring sensor mounted on the strings (4) of the racket (2) and arranged to output signals for the strength of the vibrations generated by the ball, means for processing said signals using microprocessors that analyse the signals and determine a measured value of the ball velocity, and means (6) for displaying said value. The processing means comprise a calibrating unit for automatically correcting the measured value depending on at least the features of the racket and the ball in order to provide a highly accurate and reliable result. Said measuring device is miniaturised and inexpensive and fits in a small housing (3) mounted on the racket (2) to enable the player to read the velocity value directly. The device is useful in any sport or game involving a projectile and a striking element, particularly in tennis.

摘要： A device and method for detecting microorganisms in a specimen by culturing the specimen in a sealable specimen container with a culture medium and detecting microorganisms in the specimen by measuring changes in pressure within the container caused by their metabolic activity during culturing. Pressure changes are measured using a sensor having a deformable section in communication with the container and a piezoelectric apparatus, such that the piezoelectric apparatus is deformed by changes in pressure within the specimen container and an electrical signal is produced by the deformation. The electrical signal is processed to detect any change in the rate of change of pressure, and thus detect the growth of microorganisms.

摘要： A pressure/force transducer having a sensor body with a load-receiving member at one end, a load button positioned within the sensor body and having a curved surface in surface-to-surface continuous contact with the load-receiving member, a piezoelectric plate positioned within the sensor body and in contact with the load button, and a signal processor for converting the electrical charge produced by the piezoelectric plate into a humanly perceivable signal. A preloading member is connected to the sensor body so as to adjustably force the load button into surface-to-surface contact with the load-receiving member. The load-receiving member is integrally formed with the sensor body. This load-receiving member has a radiused corner connecting the member to the sensor body. The load button is a generally cylindrical member with a generally curved surface in contact with the load-receiving member.
