Patent CA-2213115-C (CA)
Inventor: CHEN MAKAN
IPC: H01L39/16
Filed: 1997-08-15
Granted: 2005-05-03
Abstract: On transition from the superconducting state to the normal conducting state, current limiters having a high-temperature superconductor (3) increase their electrical resistance and thereby limit an electric current which is flowing through them. To provide electrical stabilization, the high-temperature superconductor (3) is combined with a silver foil (1) having a layer thickness of < 50 µm to form an extensive composite conductor with good conductivity. The ratio of the layer thickness of the high-temperature superconductor (3) to that of the silver foil (1) should be < 1/10. To produce this composite conductor (1, 3), the silver sheet (1) is placed on one side on a 2 mm thick MgO powder layer and, on the other side, is covered with a 600 µm thick so-called green sheet which contains a high-temperature superconductor powder and an organic binder. In order to stabilize the high-temperature superconductor mechanically after it has been fused together, a 200 µm thick layer consisting of glass or carbon fibers and epoxy resin is applied by vacuum impregnation to at least one side of the composite conductor (1, 3). In order to produce resistive current limiters, current limiter elements in sheet form, having the specified layer structure, are cut to form meanders and are bonded or pressed onto one another in at least two layers, if appropriate with the interposition of cooling elements. Inductive current limiters are obtained by bending flexible sheets of this type to form tubes and soldering a metal strip (5) of silver over a gap (9) in the ring.

Abstract: Ce procédé permet de détecter de manière fiable une erreur de contact survenant dans une section de contact venant en contact avec une carte de CI. Le niveau d'un signal de remise à zéro fourni à la borne de remise à zéro (RST) d'un circuit intégré (21) monté sur la carte de CI (20) via une section de contact (11), est maintenu bas, de même que le niveau d'un signal d'horloge fourni à une borne d'horloge (CLK) du circuit intégré (21) par une section de contact (11). L'énergie nécessaire au circuit intégré (21) est ensuite amenée à une borne d'alimentation (Vcc) du circuit intégré (21) par la section de contact (11). A ce moment la tension fournie à la borne d'entrée/sortie (I/O) du circuit intégré (21) par la section de contact (11) est comparée avec un niveau de référence prédéterminé par un comparateur (16). Lorsque la tension est inférieure à ce niveau prédéterminé, le résultat est considéré comme une erreur de contact située au niveau de la section de contact.

Abstract: This invention provides absorbent products, having a permeable cover made of a microperforated fibrillated thermoplastic film that has improved properties such as intimate, but nonoccluding contact with the body, yet providing comfort and resilience and immediate fluid acceptance and distribution. The cover is characterized by having non perforate regions and perforate regions , the perforate regions having a plurality of microholes defined by a network of fiberlike elements, the perforate regions being, at least in part, at elevations that are higher than the nonperforate regions. The perforate regions are caused to be at higher elevations by methods such as tensioning the cover or by partly adhering the cover to the absorbent body of the produ ct or by combinations thereof. The microholes may be of different sizes and shapes. One embodiment provides an absorbent product having a cover with apertures larger than microholes, alone or in addition to microholes, and greater open area, so that viscous fluids such as menses can readily flow through, the cover having for example at least one group of large apertures or at least two different size groups of apertures. Additional improvement of fluid acceptance and distribution properties is obtained by corona discharge treatment of one side of thefilm before microperforating and by treating the microperforated film with surfactant.

Abstract: The digital sampler circuit processes an output signal from a high gain analog amplifier having as input an infrared motion detector output signal and a negative low pass filtered feedback signal. The amplifier output signal is a substantially square pulse signal having an irregular frequency and duty cycle and has an average duty cycle indicative of a DC level and a slow change in the DC level of the detector output signal. The sampler circuit includes a detector circuit for detecting the amplifier output signal and discriminating at regular intervals a high/low state of the output signal, and generates a high/low feedback signal corresponding to the high/low state of the output signal detected. The high/low state of the output signal is analyzed over a predetermined number of the intervals to obtain a ratio value for producing an output digital signal sample value. The digital sample value is a measure of the DC level and the change in the DC level of the detector output signal. The digital sample is accurate and requires a single comparator and relatively simple circuitry.

Abstract: The present invention relates generally to a method and apparatus for evaluating the resistivity of invaded formations at high apparent dip angle. A multi-array induction tool having a plurality of arrays is disposed in a borehole. Signals from a subset of coils of the array are selected to probe different volumes of the formation surrounding the borehole. The maximum entropy method is used to process data from the subset of coils to effectively remove distortions produced by shoulder and dip effect in the presence of shallow, moderate, or deep invasion. After processing the data, the resulting multi-array induction log will indicate a conductivity profile for the subset of coils which is substantially identical to that of an array in a thick bed, without dip or layering, with the same invasion profile. A 1D radial inversion of the resulting logs at each point in depth will give a closer estimate of the actual formation parameters, R xo, R t, and the invasion radius.

Title: System for short range wireless data communication to inexpensive endpoints
Inventor: SHOBER R ANTHONY
IPC: H04J1/00
Filed: 1999-03-30
Granted: 2002-10-01
Abstract: A system provides short range wireless data communication from a central control point (e.g., interrogator) to inexpensive endpoints (e.g., tags). The endpoints utilize the technology of modulated backscatter for transmission from the tags to the interrogator. The system uses a new downlink protocol for data transmission from the interrogator to the tags and a new uplink protocol for data transmission from the tags to the interrogator. Both protocols use a backoff/retry algorithm to randomly retransmit any non-acknowledged messages. System capacity from the tags to the interrogator is further enhanced by the use of uplink subcarrier frequency division multiplexing.
