Title: Adaptive message routing for multi dimensional networks
Inventor: NUGENT STEVEN F
IPC: H04L12/56
Filed: 1991-08-30
Abstract: A plurality of processing nodes comprising processing means for processing information and router means for routing messages are connected in a multi-dimensional network (A) with an identical or redundant message passing multidimensional network (B) of routers being connected to network A. Each router comprises four types of channels for message passing: 1) a channel to transfer information between a router and a processor coupled to the router, 2) a channel to transfer information in an X direction, 3) a channel for the Y direction, and 4) a channel for the Z direction. This connectivity allows messages to pass between nodes within network A, between routers within network B, or between network A and network B by passing through a router. Messages are routed in networks A and B by routing first in the X-dimension and then in the Y-dimension. The present invention transitions between A and B networks when contention is encountered in the X or Y direction, if the appropriate Z channel is available. If an X or Y channel is not immediately granted, a request is made for the Z-channel. <IMAGE>

Patent GB-2265747-A (GB)
Title: Method and apparatus for detecting data track misregistration
Inventor: ROSSER S WILSON
IPC: G11B11/105
Filed: 1992-06-24
Abstract: Apparatus for dectecting data track misregistration is described. The present invention involves the interaction of a microprocessor (6B) with a demodulator (5). Microcode within the microprocessor (6B) initiates a misregistration scan of all data tracks at specific intervals to generate a calibration offset table that is used to direct the heads during the subsequent interval. A demodulator (5) obtains the peak values of calibration servo bursts, (401, 402), displaced one-half of the track width to either side of a track, and outputs a timing pulse proportional to their respective peaks voltage values. A timer (6C) within the microprocessor (6B) extracts the time values, and the misregistration displacement is calculated by the comparison of the inner burst and outer burst time values. The calculated displacement is used in the offset table for subsequent disk references. <IMAGE>

Patent GB-2281121-A (GB)
Title: Fourier transform spectroscopy
Inventor: TURNER ANDREW
IPC: G01J3/447
Filed: 1993-08-20
Abstract: In FT-DIRLD (Dynamic Infra Red Linear Dichroism) apparatus partly represented in Fig. 1, units 100 - 105, responding to the output IB of an optical path difference (OPD) scanning interferometer having a sample in one arm, cause unit 106 to yield an interferogram combining static and dynamic dichroism interferograms. Reference signals respectively in phase and quadrature with cyclic sample strain are derived from rheometer 102 which applies the strain. At each OPD point of predetermined uninterrupted scans, controller 108 routes simultaneously data of the combined interferogram and the reference signals to respective channels of multiplexer 107. A microprocessor subsequently performs a best-fit-to-an ellipse sorting of the data and for each OPD derives: A) the value of the interferogram unaffected by sample modulation; B) the corresponding in phase term; and C) the corresponding in quadrature term; furthermore, from the A, B, C data-point series it generates the interferogram of each series and transforms it into a spectrum. DIRLD analysis is achieved asynchronously and in continuous fast scanning. <IMAGE>
Patent GB-2271435-A (GB)
Title: Copying multiple holographic elements
Inventor: BRANDSTETTER ROBERT W
IPC: G03H1/26
Filed: 1993-10-05
Abstract: The method comprises the steps of forming a master multiple holographic element 28 having an absorption grating pattern that produces a given index of refraction pattern across the master, coating the master with a layer of a photopolymer 72, and directing a recording beam 56 to and through the master and into the photopolymer layer. The absorption grating pattern of the master modulates the amplitude of the recording beam, and the modulated beam causes the monomers of the photopolymer to form a monomer pattern that produces the given index of refraction pattern across the photopolymer layer. The monomers in that pattern are then polymerised to form thereby a copy of the multiple holographic element, and the polymerised layer is removed from the master. <IMAGE>
Patent GB-2283315-A (GB)
Title: Ice detector
Inventor: PRITCHARD GARY ROBERT
IPC: G01J1/02
Filed: 1993-10-30
Abstract: An ice detector which avoids false readings, eg due to snowflakes, comprises a duct 10 which may be attached to a helicopter body by a stand 12, an electrically conductive probe bar 16 across the duct, and pairs of diametrically opposed light emitters 20 and sensors 21. In icy conditions, ice accretes on the probe 16, progressively blocking the light reaching sensors 21, and the interval between the sensor output crossing an upper and a lower threshold is used to provide an indication of the icing conditions. The sensor output is sampled at short intervals during accretion, and if any sample differs from the previous one by more than predetermined step, this is interpreted as a momentary reduction, eg due to a snowflake, and ignored. After the sensor output has fallen below the lower threshold, the probe is heated to melt the ice to allow repetition of the measurement. Air from a nozzle 14 may draw air through the duct 10 by the venturi effect. <IMAGE>
