Patent EP-0394257-A1 (EP)
Title: Low power digital receiver.
Inventor: YESTER FRANCIS RICHARD
IPC: H03J5/02
Filed: 1988-06-06
Abstract: A low power digital receiver (10) is provided that contemporaneously selects the lowest possible sampling signal frequency (34) (from a plurality of available sampling signals), and received signal level (28) to properly digitize (32) and recover a desired signal. Digitization is performed after the first IF using broadband stages (28, 30, and 32) that are temporarily enabled (44) to rapidly digitize the first IF signal. This, together with the low sampling rate, minimizes the power consumption of the receiver (10) thereby permitting portable and mobile digital receiver embodiments.

Abstract: With this device, it is possible to open the car door (30) of a lift car located in the area of a floor together with a shaft door, and in fact in the normal case automatically driven by a drive (36) or, in the event of a power failure, manually by a passenger. If the lift car is located outside a floor, the car door remains locked by the same device. The car door (30) is driven by a band-shaped drive means (42) via a driving parallelogram (1) consisting of a rigid and a movable cam (2, 3) and arranged on the top part of a car door. For the free travel, the driving parallelogram (1) is closed; it opens for coupling to the shaft door between two coupling rollers, arranged on the shaft door, before movement of the doors takes place. The movable cam (3) of the driving parallelogram (1) has a compressible stop cam (5) which is lifted from a rigid cam carrier (4) by leaf springs (6) during the travel and during holding outside a floor. During the coupling with the coupling rollers (44, 45) of a shaft door, the stop cam (5) is pressed against the rigid cam carrier (4). This displacement is utilised for unlatching a car door latch (12).

Abstract: The invention relates to a method of manufacturing a semiconductor device comprising a semiconductor body (1) having a buried insulating layer (7). Such a type of semiconductor device is known as a device of the SOI type. According to the invention, the starting material is a substrate (1) of monocrystalline semiconductor material with a top layer (2). Ions are implanted into a zone located under the top layer so that the zone becomes selectively etchable with respect to the remaining part of the substrate. The zone is then etched away, a cavity then being formed between the top layer(2) and the remaining part of the substrate (1). The cavity is filled at least in part with insulating material (7). By known techniques, semiconductor circuit elements can be provided in the top layer (2) thus disposed on the insulating layer (7).

Abstract: In a rolling bearing arrangement the heaviest loaded contacts are normally on the innerring. To avoid damping by interfaces from the innerring to the rolling bodies and from the outerring to the housing a special transducer is designed. However, the problem on mounting this transducer on a rotating shaft is that the generated acoustic emission signals, measured with a piëzoelectrical transducer (5) generating electrical charges, have to be sent to the outside part of the arrangement without harmful noise. 
     A solution for this problem is found by converting the charges into current changes from a current source. The current source is also used to become a two wire signal path wherein the resistance of the rotating contact (10) has no influence on the output voltage.

Abstract: The foldable automobile window shade (10) generally includes a first plurality of substantially rigid, planar elements, joined together by hinges such that they form a first accordion fold portion (12) of the shade, a second plurality of rigid, planar elements forming a second accordion fold portion (14) of the shade. The shade also includes a hinge (44) that links the first and second accordion fold portions (12, 14). The single hinge (44) links end elements (40, 42) of the first and second accordion fold portions. In a horizontal expansion mode, the first and second end elements (40, 42) have planar surfaces that are adjacent to each other and the first and second accordion fold portions (10, 12) extend outboard from either side of the adjacent end elements (40, 42). In a vertically expandable mode, the end elements (40, 42) are co-planar with respect to each other. The first and second accordion fold portions (10, 12) are disposed above the respective first and second end elements (40, 42) and therefore the shade can be vertically expandable as desired to cover the interior of the automobile window.

Abstract: An Improved Ranging System (10) that overcomes the problem of shadowing encountered in conventional triangulation systems is disclosed. The key to the enhanced performance that is achieved using the present invention is the built-in redundancy provided by a four aperture mask (27). 
     Light (14) from a laser (12) is directed to a dual purpose focusing and objective lens (20). An object (22) whose range from a reference plane (23) must be determined is illuminated by the laser light (14), and reflected rays (24) pass back through the lens (20) to a mask (26) having four apertures (27). The beams (24) that transit the mask (26) form spot images (33a and 33b) on the surface of a detector (32). By measuring the distance between the opposite pairs of spot images (33a, 33b) projected on the detector (32), the distance from the object (32) to the reference plane (23) is calculated.

Date Jun. 15, 1989.A shoe sole (1) manufactured of one or more pieces of a resilient material, such as plastics, natural or synthetic rubber, including a recess extending from below the heel and forward to the forefoot. The recess only allows the longitudinal circumferential rims of the shoe sole to come into contact with the walking surface when the user of the shoe is standing on said walking surface. A shock-absorbing projection (2) is provided in the recess opposite the heel bone of the foot, said projection not coming into contact with the walking surface at a low pressure load. At a high pressure load, such as when the user is walking or running, the shock-absorbing projection (2) comes into contact with the walking surface. In this manner the shocks usually affecting the heel of the shoe are moved to the heel bone as well as absorbed in the best possible manner. When the user is standing still the resilience is achieved by the circumferential rim of the shoe sole absorbing all the pressure in the heel area. The optimum absorption of shocks when the user of the shoe is walking and running is achieved by the pressure in the heel area being absorbed by the projection (2) situated just below the heel bone of the foot.

Abstract: L'interféromètre hétérodyne décrit, qui sert à effectuer des mesures simultanées et indépendantes d'amplitudes et de phases, comprend un dispositif de décomposition de faisceau (BS), qui décompose le faisceau de lumière incident en deux parties avec des amplitudes égales et une déviation angulaire (alpha), impose deux décalages de fréquence inégales (f1 et f2) aux deux faisceaux et confère une modulation d'amplitude aux deux faisceaux en quadrature de phase à la fréquence (fs). Les deux faisceaux sortant du dispositif de décomposition de faisceau (BS) sont focalisés par une lentille (L1) perpendiculairement sur la surface d'un objet (O). Après réflexion sur la surface de l'objet, les deux faisceaux traversent une deuxième fois la lentille et le dispositif de décomposition de faisceau, pour être recombinés. Les fréquences et les amplitudes des deux faisceaux sont décalées (ou modulées) à nouveau après le second passage.

Abstract: Signals produced by brain activity are measured by each sensor of an array of magnetic and/or electrical sensors external to but proximate to the head (or other portion of the body) of a subject. The measurements obtained simultaneously from all of the sensors are combined in a manner to permit selective measurement of the electrical activity from a specified location within the body, or alternatively, to permit the location in the body producing a particular type of response to be identified. The instantaneous measurement of each sensor is scaled by a weighting coefficient for that sensor, and the products added over all of the sensors. Preferably, the weighting coefficients are calculated from the covariance matrix of the measurements made by the array of sensors. Alternatively, the weighting coefficients may be calculated from a mathematical model of the portion of the body being measured that includes information on the shape of the potential source, the extent or type of source activity, the electrical and magnetic properties of the media, and the locations and orientations of the sources and the sensors.
