Title: Smart antenna CDMA wireless communication system
Inventor: LIU HUI
IPC: H04B7/26
Filed: 1997-12-12
Granted: 2001-03-29
Abstract: A TDD antenna array S-CDMA system for increasing the capacity and quality of a wireless communications is disclosed. By simultaneous exploiting the spatial and code diversities, high performance communications between a plurality of remote terminals and a base station is achieved without sacrificing system flexibility and robustness. The time-division-duplex mode together with the inherent interference immunity of S-CDMA signals allow the spatial diversity to be exploited using simple and robust beamforming rather than demanding nulling. Measurements from an array of receiving antennas at the base station are utilized to estimate spatial signatures, timing offsets, transmission powers and other propagation parameters associated with a plurality of S-CDMA terminals. Such information is then used for system synchronization, downlink beamforming, as well as handoff management. In an examplary embodiment, the aforementioned processing is accomplished with minimum computations, thereby allowing the disclosed system to be applicable to a rapidly varying environment. Among many other inherent benefits of the present invention are large capacity and power efficiency, strong interference/fading resistance, robustness power control, and easy hand-off.

Title: Data transmission system employing a combination of block encoding and convolution encoding for error protection
Inventor: PIRET PHILIPPE MARIE OCTAVE AD
IPC: H04N1/41
Filed: 1986-06-12
Granted: 1989-09-28
Abstract: A system is described for transmitting data words composed of more significant bits and less significant bits. The less significant bits of a data word are, by means of matrix multiplication, encoded into a first redundant proto-code word. The more significant bits of a data word are by means of matrix multiplication, and different delays over respective numbers of recurrence times of the arrival of the data words encoded in a set of further redundant proto-code words. A code word is formed by means of modulo-2-addition of code words, so that for the less significant data bits a block code is realized, while for the more significant data bits a convolutional encoding is realized. In the decoding, the more significant bits are decoded by means of Viterbi decoding, while the Viterbi metric is determined from the deviation between the reconstructed contribution from the lower significant bits and the actually received contribution therefrom.

Title: Colour CRT phosphor screen prodn. - uses identical voltage between electron gun and colour selection shadow mask as in CRT operation
IPC: H01J9/227
Filed: 1970-04-29
Abstract: The produced screen of the cathode-ray tube consists of discrete phosphor elements, which are produced by electron irradiation of a continuous electron sensitive layer through the aperture of the shadow mask. Between the latter and the electron sensitive layer is produced an electric field, reducing the cross section of the electron beam passing through the shadow mask apertures. Thus the produced phosphor elements have a smaller active surface than the cross sections of the apertures of the mask. During the screen production the same voltage is applied between the electron gun and the shadow mask as in the operation of the finished cathode ray tube. An external magnetic field may be applied, which can be identical with the earth magnetic field to be expected in the tube operation.

Title: Time division multiplex system - uses method for recovery at receiving end of primary cycle of several primary time multiplex systems
IPC: H04L7/033

Abstract: The primary TDM systems are combined at the transmitter into a higher order system. This is done by insertion or omission of individual timing pulses into or from a locally generated medium timing frequency, only using correction signals contained in the received multiplex bit flow; cycle deviations of primary systems are displayed. Insertion or omission takes place in a pulse train whose repetition frequency corresponds to an n-th multiple of the mean, locally generated primary clock frequency, and is carried out in two steps in two similar correction stages, one of which is centrally allocated to all primary systems, and the second individually allocated to each primary system.

The blocking element which in the safety position covers the rear end of the initiator is a plastically deformable aluminum plate (18) supported by a steel plate (19). An annular chamber is provided for expanding the explosion gases of the initiator. The aluminum cover on steel is deformed so that it is forced into the separating gaps.

Title: Digital network for locating power line short circuits - stores current and voltage at both ends of line in digital form before performing algorithmic calculation
IPC: G01R31/08
Filed: 1971-03-10
Abstract: The digital monitoring network for locating the position of power transmission line short circuits, monitor and stores the voltage and current conditions at both ends of the transmission line concerned before the fault circuits operate and which then uses this data in a digital algorithm to estimate the fault location. At each end of the transmission line pair (a, b) concerned, is mounted a voltage and current transformer. Signals are taken from these via analogue to digital converters to data storage units and to cutout control networks (SA1, SA2) which operate isolating switches. If a line fault occurs the stored digital data is transmitted via transmission units to an evaluation network and computer where an algorithm is used to estimate the location of the fault.

Title: Slide path for metal hooks transporting meat portions - formed by immovable rail detail of low friction synthetic
IPC: B65G9/00
Filed: 1971-05-27
Abstract: Trim of synthetic material having a low coefft. of friction is fitted to the rails, esp. in refrigerated stores, on which steel hooks supporting sides and pieces of meat, slide. The metal rail is covered only in the zone contacted by the meat hook, and the synthetic material is fixed so that it cannot be displaced. Where the hook makes contact with it, its surface is curved across its width. The rail may be formed by a deformed tube in the mantle of which a longitudinal groove is pressed to a width which is wider at the bottom so that the synthetic material is gripped and held securely. The rail can be used without problems inside and outside cold stores. Its sliding characteristics are good and the hooks cannot freeze on to it. Risk of soiling meat is eliminated.(DS).
