Title: Data interleaving process for radio transmission
Inventor: WILSON ALICE
IPC: H03M13/27
Filed: 1994-10-26
Abstract: An interleaving process in which data is interleaved or interleaved data is de-interleaved. Input data units are distributed over a plurality of output groups of data units. Thus, in GSM telephony, input bits are distributed over nineteen transmission bursts. Incoming data units are written to a contiguous RAM 1618 and output groups are read from said RAM. Addressing circuitry controls the writing and reading to the RAM, such that data units are stored until required for an output group. After data has been read, these read locations are reused for the storage of new input data, such that the duration over which a particular memory location stores a data unit depends upon the interleaving process delay for that particular data unit. The addressing circuitry includes modulo counters, each arranged to generate addressing signals for a respective set of memory locations within the RAM. Look-up tables are used to select modulo counts so as to provide conventional addresses to the RAM. The interleaving process is partially effected during the writing of the data into storage, and is completed during the reading of the partially interleaved data from storage. <IMAGE>

Title: Charged particle beam drawing data production apparatus
Inventor: KAMIYAMA KINYA
IPC: H01J37/302
Filed: 1996-01-08
Abstract: A CPU divides a design layout data into units of graphic data processing area (step S1) and executes elimination of duplication and tone reversal processes in both X direction and Y direction (steps S2A, S2B) for the respective graphic data processing areas. Moreover, it performs, with reference to a micro graphic dimensional value, the graphic data processing result judging and selecting function in both the X direction and Y direction (step S3) for the respective graphic data processing areas. Namely, the CPU judges when the dimension of a basic graphic after the elimination of duplication and tone reversal processes is no larger than the micro graphic dimensional value, compares the two by determining the sum of such micro graphics, for example, in the X, Y directions and selects the graphic data submitted to the elimination of duplication and tone reversal process for the direction with the smaller value. The CPU further performs prescribed processing (steps S4, S5) of this graphic data to complete the production of drawing data.

Title: Demodulators
Inventor: BEECH BRIAN HERBERT
IPC: H04L27/233
Filed: 1997-03-21
Abstract: The present invention concerns a method of demodulating an input signal and to a tuner demodulator for performing the method. The invention provides for enhanced phase noise performance in the presence of spurious noise components. The invention employs a tuner demodulator having a frequency converter to frequency convert the input signal. The frequency converter includes a local oscillator controlled in frequency by a phase lock loop including a phase comparator which receives an input derived from the local oscillator and an input derived from a frequency synthesizer. A frequency divider is used to displace the frequency of the local oscillator relative to the frequency of the frequency synthesizer such that the first order spurious noise components generated by the frequency synthesizer fall outside the bandwidth of the phase lock loop.

Title: Leakproof,valve-regulated,maintenance-free lead acid battery
Inventor: REY GONZALO C
IPC: H01M50/367
Filed: 1995-08-15
Abstract: A valve-regulated, maintenance-free lead acid battery (10) has plate compartments (18a, b, c) which are substantially surrounded by chambers (20a, b, c) that contain electrolyte absorptive material (50). Electrolyte droplets (40) escaping through the pressure relief valves (33) of the battery are directed to flow over the absortive material in the chambers and are absorbed by it, while evolved gas escapes through a vent (47) without appreciable pressure drop. The chambers also protect the plate compartments from impact and absorb electrolyte which might otherwise leak from the plate compartments.
