Title: Liquid crystal display and method of manufacturing the same
Inventor: SEKIGUCHI KANETAKA
IPC: G02F1/1365
Filed: 1995-07-14
Abstract: Upper electrodes (10, 11) and a lower electrode (2) are so provided as to be at right angles to each other on a base board (1) of a liquid crystal display, and two non-linear resistance elements (13, 14) are formed by the upper electrodes, an insulating film and the lower electrode. Either of the upper electrodes is connected to a signal electrode (9), the other connected to a display electrode (12) which constitutes a display image element. A connection portion (4) by which an anodic oxidation electrode (3) and the lower electrode (2) are connected together is partly cut off and so the lower electrode is insular. The display electrode (12) has an overlapping portion (15), where a two-layer film comprising the metal film of the joint portion (4) and the insulating film is left, under the display electrode (12). Owing to this arrangement, the asymmetric current-voltage characteristic due to the voltage applied to the signal electrode (a) is turned symmetric, and the DC component of the voltage applied to a liquid crystal layer is decreased. A decrease in the quality of the liquid crystal, a decrease in the contrast, and the occurrence of an image sticking phenomenon which are a flickering phenomenon and a after-image phenomenon are prevented.

Title: Encoding and decoding data
Inventor: EVANS MARTIN ROBERT
IPC: H04L1/00
Filed: 1997-02-22
Abstract: Algorithms for encoding and decoding Frame Check Sequences (FCS) currently perform a standard modulo-2 addition using a feedback shift register. The algorithm is equivalent to: clocking a stream of m bits through a n stage division register, where n½m; and combining input bits with bits emerging from said division register to give a bit combination used to modify said division register's state, which only on its initial state and the bit stream. The fast algorithm is implemented in a digital processor having a q-bit division register and a look-up table store. In operation, the division register is initialised to zero and the following steps are performed repeatedly, p times: - adding a next group of N input bits, modulo-2, to a least significant group of N bits in the division register, in a first adder; - using the result as an index to a look-up table parameter, stored in said look-up table store; - shifting the contents of said division register N bits to the right and adding, modulo-2, the indexed look-up table parameter to the content of the division register, in a second adder. After completion of p steps, the FCS is derived from said division register contents. Application is to GSM mobile telephone systems.

Title: Measurement of parameters of flowable material
Inventor: BRADLEY MICHAEL STANLEY ARTHUR
IPC: G01P5/02
Filed: 1998-04-16
Abstract: The present invention provides a method and apparatus for measuring a selected parameter, preferably the rate of flow of material in the stream. The method comprises arranging in the flow stream at least one barrier that occupies only part of the cross-section of the flow stream and measuring the force exerted on the barrier by the flowing material. Preferably, the barrier is made up of a series of parallel bars (14), the leading face (20) of which is slanted at 45‹ to the direction of flow (A); the impact of the material on the leading face (20) provides a force Y that is proportional to the rate of flow of the bulk material. By measuring the force Y, the rate of flow can be calculated. The slow stream may comprise a fluid or a flowable particulate material. In addition the "noise" from the measurement of force can be used to discern other properties of the slow, such as homogeneity or particle size.

Inventor: BICKERSTAFF JACQUELINE PETA
IPC: H04B1/707
Filed: 1999-07-05
Abstract: A GPS or similar needs to process signals from several satellites to obtain positional or timing information. Three improved systems are suggested for receiver channels. The first option mixes, 61-64, the translated frequency encoded signal to produce first and quadrature signals. A switch, 66, works to connect first or quadrature signals to another mixer, a respective second mixer (with early-minus late version of replica code) and then to an accumulator, 49-52. The second option generates a code replica and mask signal (where the mask signal has integer multiple of chirp period of code replica.) The encoded signal is frequency translated and mixed with the code replica and mask signal respectively. The third option is used to detect multipath interference by mixing encoded signal with first and second signal respectively and integrating. The ratio of outputs is compared and an interference indication is given if the ratio is not as expected.
