Patent EP-0458527-A2 (EP)
Inventor: GERDES RICHARD CONWELL
IPC: H03M3/02
Filed: 1991-05-16
Abstract: Improved analog to digital and digital to analog signal processors are disclosed wherein a quick approximation of the input signal to the signal processor is attained and a more accurate approximation is later attained for the input signal. For the analog to digital conversion, a standard analog to digital converter having a finite resolution or a predetermined quantization error is used to create part of the digital representation. The remainder of digital representation is created by processing an error signal due to the finite resolution of a standard analog to digital converter and the infinite resolution of the analog input signal to a delta modulator. In a digital to analog signal processing circuit, the first part of the digital representation is converted by a standard digital to analog converter and the remaining portion is integrated into a frequency limited analog signal and then summed to reconstruct the analog signal. To avoid overshoot, the integrators of the signal processors are preset based upon the increase or the decrease in the first part. Further, the rate of integration is controlled so that the rate slows as the digital representation of the analog signal becomes increasingly more accurate representation of the input signal.

Abstract: An improved Sagnac interferometer includes a broadband light source (100) that comprises a fluorescent optical medium which is pumped by light from a pump source with a sufficient intensity to cause the fluorescent optical medium to generate temporally incoherent light by superfluorescence. In the preferred embodiment, the superfluorescent optical medium comprises an optical fiber (130) which is backward pumped. The light signal input into the sensing loop (142) of the interferometer is amplified by a modulator, output from the interferometer loop (142) and amplified by the optical gain of the superfluorescent fiber which acts as a light source (100) and as an amplifier. In order to avoid gain modulation in the superfluorescent fiber (130), the modulation frequency is selected so that the modulation gain depth is substantially reduced.

Abstract: In video signal recording apparatus a video signal is processed (3, 5, 6, 10, 11), such as in time division multiplexed format. A burst clock signal (B) of frequency f b  is generated (8) for recovering the video signal during a subsequent reproduction operation, and this burst clock signal (B) is added (40A, 40B) to a DC level portion (H) that is present in the processed video signal, resulting in a combined signal. The combined signal is frequency modulated (14A, 14B) and recorded ( 70 ) on a record medium ( 18 ). Assuming that the DC level (H) of the processed video signal is represented by a modulating frequency f a , and m is an integer, if:           f       a        ≧        m       2            f       b           , then |2f       a            - mf       b            - f       b           | ≧ 0.15f       b        and if:                     f       a        <        m       2            f       b           , then |mf       b            - 2f       a            - f       b           | ≧ 0.15f       b       .

Abstract: To simplify the manufacture of III/V semiconductor field-effect transistors, a T-shaped gate (5) is first applied lithographically to the surface of a heterolayer (2) applied to a substrate (1). In a subsequent lithographic step, a mask which defines the respective transistor element is applied to the heterolayer (2). That area of the heterolayer (2) which is roughly defined by the crossbar (5a) of the T-shaped gate (5) and left free by the mask, and the surface of the crossbar (5a) of the T-shaped gate (5) are then vapour-coated with a metal-vapour beam to form source (3) and drain (4) on either side of the area shaded by the crossbar (5a). In a third process step, the areas (10) situated between the respective transistor elements are rendered electrically insulating by ion implantation without lithography. This process saves one lithographic step and the other series of process steps obviates an expensive centring of the gate (5) between source (3) and drain (4). <IMAGE>

Abstract: An elapsed time recording device includes a counter (130) for incrementally advancing a count value from an initial value towards and beyond a threshold in response to successive clock pulses of a clock signal. Control logic (140) enables the counter (130) to incrementally advance the count value in response to a first input (pin 3) and a second input (pin 1) being at or near a first voltage level, and holds the count value in response to the first input (pin 3) being at or near a second voltage level and the second input (pin 1) being at or near the first voltage level. Setting logic (210) sets the count value to a value beyond the threshold in response to the first input (pin 3) and the second input (pin 1) being at or near the second voltage level when the count value is between the initial value and the threshold. Because the device consists essentially of electronic circuit elements, it can be implemented in the form of an application specific integrated circuit package suitable for high volume manufacture at relatively low cost. The device is therefore favourable for use in mass produced electrical appliances. Because the count value is immediately advanced beyond the threshold in response to removal of the second input voltage, advance of the count value towards the threshold cannot be prevented or delayed by tampering with pin connections of the device.

Abstract: An ultrasonic parametric amplifier incorporates a duct (4) having rigid cylindrical wall with a periodic inner surface that undulates sinusoidally in an axial direction, and an element (16) for heating the external surface of the wall. The sinusoidal undulations of the periodic inner surface have a wavelength which is about half of the wavelength of the waves of ultrasonic energy propagating through a fluid filling the duct. The waves are amplified by synergistic interactions of the ultrasonic waves with the periodic duct walls when heat is added in a predetermined manner, thereby compensating for the exponential decrease in fluid temperature which would otherwise lead to detuning of the amplifier.

Abstract: A fiber bundle is wrapped with a tape by helically and entirely winding the tape around the bundle, while applying a constant longitudinal tension to the bundle; and thereafter unwinding and removing the tape from its last turn to gradually expose the bundle towards its basal end, while inserting the exposed portion of the bundle gradually into a cylindrical protector. The method keeps constant the outer diameter of the bundle by adjusting the tape tension, even if the bundles are composed of varied numbers of fibers in one protector, so that a wider use of the protector is realized. In the method, the wrapping operation does not produce any damaged fibers from which a fluid such as blood leaks in a hollow fiber apparatus, and no later adjustment is necessary for the wrapped bundles, thus improving the production efficiency.

Abstract: An ultrasonic device having an acoustic transducer (10) with a lamination (22) of parallel integrated circuit chips (24-38) having active circuitry (60, 62, 66 and 68). A backing member (16) made of a material for attenuating acoustic waves provides Z-axis conduction of signals from the parallel integrated circuit chips to individual piezoelectric elements (12). Preferably, each piezoelectric element is operatively associated with a particular circuit that is within the acoustic shadow of the element, so that the lamination of chips does not add to the cross sectional area of the transducer. The integrated circuit chips are coterminus at first edges to provide a planar contact surface having a pad grid array of contact pads (44) for connection with conductors (18) extending through the backing member. In one embodiment, the piezoelectric elements provide a two-dimensional array of elements that corresponds to the pad grid array. Circuitry on the integrated circuit chips can include protective diodes, preamplifiers and one or more multiplexers.

     A cylindrically-shaped magnetic material (20) is cut to match the shape of the teeth (11) and is separated into a first rotor member (1) and a second rotor member (2). A plurality of teeth (11) is formed on the first rotor member (1), and teeth are formed on the second rotor member (2) so that they are positioned in the spaces in the cylindrical surface formed by the teeth of the first rotor member. The two rotor members (1,2) are mechanically joined by laying each of two rings (8,9) across the tips of the teeth (11) of one rotor member and across the bases of the teeth of the other rotor member. 
     Given this construction and method of manufacture, rotors can be manufactured in fewer manhours, electrical efficiency can be improved by increasing the number of poles, and the incidence of defective products is decreased, which means that manufacturing yield can be increased. In addition, because the fabrication of the teeth (11) can be automated and the welding can be performed easily from the outside, fabrication precision can be increased and quality stabilized.

Abstract: A method for automatically determining the existence of retrograde conduction in a pacemaker patient. At a selected ventricular pacing rate, A-senses are detected, and V-pace to A-sense intervals are measured. If the measured intervals are consistent, it is possible that there is retrograde conduction. To confirm that the A-senses were not due to noise, atrial premature beats, etc., subsequent ventricular pacing pulses are generated in a manner that eliminates the possibility of atrial beats being due to retrograde conduction; a series of simultaneous atrial and ventricular pacing pulses are generated. If A-senses consistent with the previously measured intervals are not sensed, retrograde conduction is confirmed.
