Title: Multiple access up converter/modulator and method
Inventor: ROTTINGHAUS ALAN P
IPC: H04Q7/38
Filed: 1996-02-29
Abstract: A multiple access digital up converter/modulator includes selectors (1606, 1608) having inputs (1602, 1604) and outputs coupled to first and second interpolating filters (1610, 1626). The output of the first interpolating filter is selectively coupled to a first mixer (1612) and a first adder (1622), the first adder also receiving a first phase value, and the output is coupled to a first phase accumulator (1616) the output of which is coupled to a first sinusoid generator (1614) and selectively coupled to a second sinusoid generator (1630). The outputs of each of the first and second mixers are selectively coupled to an output adder (1634) and to inputs of the first and second mixers. The output of the second interpolating filter (1626) is selectively coupled to a second mixer (1628) and a second adder (1638), which also receives a second phase value and the output of which is coupled to a second phase accumulator (1640) the output of which is selectively coupled to the second sinusoid generator.
Patent GB-2308933-A (GB)
Title: Bidirectional voltage translator
Inventor: NG RICHARD
IPC: H03K19/0185
Filed: 1996-12-18
Abstract: A bidirectional voltage translator couples signals between ports 106,110 which have different voltage signal levels, for example 3 V and 5 V ports in a radiotelephone and an attached accessory. When an asserted signal arrives at port 106, open-drain buffer 212 passes the signal to the port 110 while buffer 214 disables the open-drain buffer 213. Similarly, when an asserted signal arrives at port 110, open-drain buffer 213 passes the signal to the port 106 while buffer 215 disables the open-drain buffer 212. If asserted signals arrive at both ports at the same time, then both main buffers 212,213 are disabled. The propagation delay of the main buffers may be longer than those of the controlling buffers 214,215. In an alternative embodiment, the data direction may be controlled by a state machine (figures 4-6) based on a PLD, microprocessor or flip-flop circuit.
Patent GB-2308318-A (GB)
Title: Polymeric films
Inventor: SHIMELL RICHARD JOHN
IPC: C08J7/052
Filed: 1996-12-20
Abstract: Polymeric films consist of at least one layer 1 of a thermoplastic polymer having thereon a layer of a dispersion of a particulate filler 2 in a dispersant 3, the dispersant consisting of or containing a tackifier. The dispersion can form an outer layer or an internal layer of the films. Such films have good barrier properties to oxygen and other gases and are of particular use in the ensiling of vegetable matter such as hay and straw. If the dispersant is migratory and/or volatile it can enable the dispersion to concentrate, thereby enabling dispersions with low concentrations of filler to concentrate.

Title: Performing synchronisation of a despread code and a spread code
Inventor: KONDO TAKAYUKI
IPC: H04B1/707
Filed: 1997-03-21
Abstract: A method for synchronism acquisition between a spread code sequence 20 at a transmission side and a despread code sequence 22 at a reception side in spread spectrum (SS) communication such as a direct sequence (DS). The method includes steps of (a) calculating correlation values at 53 for the despread code 22 at different chip phases with successively displacing in 52 the chip phases of the despread code at intervals of 1/N chip over a full search range for the synchronism acquisition, N being an integer equal to or larger than 2, (b) selecting at 55, as candidates, a plurality of chip phases which correspond to comparatively high values from among the correlation values, (c) adding at 55, for each of the candidates, correlation values of chip phases adjacent the candidate to the correlation value of the candidate, and (d) determining one of the candidates which exhibits a highest result of addition as a chip phase having acquired synchronism. Then unit 56 compares outputs from unit 55 and tracking unit 40, synchronism is acquired and demodulation takes place at 30.

The device comprises a mounting frame, a first roller member (50) that is rigidly mounted on the mounting frame in fixed relation thereto, and a second roller member (60) that is rigidly mounted on a depending portion of the keyboard tray in fixed relation thereto. A rigid housing (70) substantially encases the first and second roller members in journalled relation about respective first and second circumferential bearing surfaces on the first and second roller members so as to hold the first and second roller members in fixed spaced relation to one another and so as to permit relative rotation of the housing with respect to the first and second roller members. A constant length closed-loop band (80) is operatively mounted around both of the first and second roller members in fixed indexed engagement therewith so as to surroundingly link the first and second rollers members for planetary movement of the second roller member about the first roller member within the rigid housing, such that the second roller member remains substantially rotationally aligned with respect to the first roller member. A lock is operatively mounted between the second roller member and the rigid housing member to selectively preclude the relative rotation of the second roller member with respect to the rigid housing, which, in turn, selectively locks the keyboard tray in any one of said plurality of work positions.

Patent GB-2323469-A (GB)
Title: Method of linearisation of ion currents in a mass spectrometer
Inventor: HOLKEBOER DAVID H
IPC: H01J49/42
Filed: 1998-03-23
Abstract: Ions produced in ionization volume 5 by electrons from emitter 3 impacting with gas molecules, are focused into a beam and directed into a mass spectrometer, e.g. a quadrupole mass filter 6. Operation of the latter selects the ions which reach ion detector 8 to produce a current indicative of the partial pressure of the gas species from which the selected ions originated. A non-linearity between detected total gas pressure and partial pressure has been observed. The invention provides a method for linearizing the sensitivity of a mass spectrometric system to allow the detector 8 to more accurately report partial pressures of a gas in high pressure areas where readings are affected by a number of loss mechanisms. Correction factors, derived from measurements of total pressure ion current by collector 11 at different test pressures, are applied empirically, or using correcting software, to expand the useful range of mass spectrometer.

Title: Silver halide light sensitive element
Inventor: ZENGERLE PAUL LEO
IPC: G03C7/388
Filed: 1998-08-18
Abstract: A silver halide light sensitive photographic element is disclosed comprising a support bearing at least one yellow image forming hydrophilic colloid layer comprising yellow image dye forming coupler of Formula I: wherein R represents a substituent, Y represents an aryl group or a heterocyclic group, and Z represents a non-metallic atomic group necessary to complete with the indicated nitrogen atom a nitrogen-containing heterocyclic coupling-off group, wherein the yellow image forming layer is substantially free of high boiling permanent solvents and nonionic polymeric stabilizers. Such photographic elements exhibit high coupler reactivity and excellent sensitometric curve shape, and yellow dyes formed from couplers of Formula I exhibit markedly improved stability to light fading when the couplers are dispersed without any high boiling solvent or nonionic polymeric stabilizer compared to coupler solvent-containing dispersions of these couplers. Additionally, the absence of nonionic polymeric stabilizers enables photographic elements having relatively thinner yellow image forming layers to be obtained.

Title: Portable position detector and position management system
Inventor: ONARI MIKIHIKO
IPC: G01C22/00
Filed: 1998-12-30
Abstract: A portable position detector 1, (41, 51) and a position management system that are capable of accurately detecting the direction of a walking body even when GPS signals cannot be received (or without reception) and thereby enhancing the accuracy of the dead reckoned position of the walking body. The portable position detector is equipped with a pedometer 12 and a geomagnetic sensor 13. With the pedometer 12, the moved distance of a walker is detected by a calculation of "the number of steps X the length of a step". The moved direction is detected with the geomagnetic sensor 13. The geomagnetic sensor detects points of which the body of the walking body arrives at substantially a highest position and/or lands by walking based on the value measured by the pedometer. The moved position of the walking body is determined based on the moved distance of the walking body estimated by control section 11 and a moved direction determined by the geomagnetic sensor 13.
