摘要： An electronic horological instrument which includes a piezoelectric crystal oscillator and a counter such as a series of count-down circuits connected in tandem. The "effective frequency of the oscillator" is adjusted by inhibiting the oscillator pulses to the count-down circuits by means of a pulse inhibit circuit. The pulse inhibit circuit is readily programable to inhibit a desired number of oscillator pulses by means of a switch arrangement that includes multi-position detented pin switches.

摘要： A driving circuit for an electrochromic display cell wherein writing and erasing of a segment is effected by relatively high write and erase transition potentials. After a predetermined transition period, the written and erased segments are stabilized at a desired coloration or transparency by application of a maintaining write potential(s) and a maintaining erase potential(s) respectively. The write maintain potential is periodically adjusted to a level whereby a predetermined charge level is maintained on the written segments. In this manner, a maintain potential on the segments(s) is periodically adjusted to compensate for degradation of the electrochromic material and to thereby maintain the desired contrast ratio between the written and erased segments.
摘要翻译：用于电致变色显示单元的驱动电路，其中片段的写入和擦除通过相对高的写入和擦除转变电位来实现。在预定的转换周期之后，写入和擦除的段通过分别施加保持写入电位和维持写入电位而稳定在所需的着色或透明度。写入维持电位被周期性地调整到在写入的段上保持预定的电荷电平的电平。以这种方式，周期性地调节段上的维持电位以补偿电致变色材料的劣化，并由此保持写入和擦除段之间的期望对比度。

摘要： A probe of very low thermal mass and fast response for a digital electronic clinical thermometer using an extremely small temperature-responsive element with leads supported between coaxial tubular members. The temperature-responsive element, with adjacent lead portions is supported on at least one substantially hemispherical cup, also of low thermal mass adhered to the ends of the tubular members. Preferably a pair of hemispherically ended cups enclose a thermocouple junction and the associated lead portions, although a thermistor may also be used as the temperature-responsive element.

摘要： An endoscope, especially for transesophageal echocardiography. An encapsulated ultrasonic transducer capsule is provided having a self-contained electro-mechanical sector scanner. A sealed housing is formed which includes axially aligned tubular sections, one of magnetic material and the other of acoustically transparent plastic. A tubular shaft is journalled axially within the housing for limited sector scanning rotation. A magnetic rotor is fixed to the shaft for operation within the magnetic housing section and a transducer element is fixed to the shaft within the other tubular section. Conductor wires for activating the transducer are fixed at one end of the capsule and extend axially through the tubular shaft for connection to the transducer. Position sensing means are incorporated within the capsule. The construction enables the capsule to be highly miniaturized and greatly improved relative to known devices of its type.

摘要： A levered scale for weighing human beings is disclosed in which weight measurement is produced by direct tensile loading of at least one stress-dependent transducer that is bonded to the central member of an improved tension link plate which is pivotally supported at one end by a U-shaped bracket and pivotally coupled at the opposite end to lever arms. The thin tension link plate, which is made of elastically deformable sheet metal, is received between the sides of the U-shaped bracket. The tension link plate is connected directly to the U-shaped bracket by a first cross pin and to the lever arms by a second cross pin. The resultant force produced by the weight of the load applied to the scale produces vertically downward movement of the lever arms thereby providing tensile loading of the tension link plate and the stress-dependent transducers bonded or deposited thereto. The end of the tension link plate supported by the U-shaped bracket is held in position while the tensile loading is applied directly to the opposite end of the tension link plate. The resultant force which is proportional to the weight of the load applied to the scale is transmitted as tensile force directly to the tension link plate thereby producing changes in transducer resistance proportional to the resultant force.
