Patent GB-2315499-A (GB)
Title: Industrial textile including photochromic material
Inventor: DRAPER MICHAEL
IPC: D21F1/00
Filed: 1996-07-23
Abstract: An industrial textile, such as an industrial belt or filter e.g. a press felt for papermaking, is composed of a polymer matrix incorporating photochromic dyes. The photochromic dyes reversibly change colour typically when exposed to ultra violet light. Incorporation of the photochromic dyes having a characteristic colour change in the polymer matrix of an industrial textile allows wear of that particular textile to be simply and efficiently identified since only fibres shedded from that textile will exhibit the characteristic colour change when exposed to ultra violet light. In this manner, those fibres shedded from a particular industrial textile may be easily distinguished from those fibres of other textiles by the particular colour change displayed and thus shedded fibres may be simply, yet effectively identified as those from a particular textile of a particular manufacturer. The dyes may be included in the fibres or yarn from which the textile is made or in a coating.

Title: Microwave vehicle alarm
Inventor: REDFERN STEPHEN WILLIAM
IPC: B60R25/10
Filed: 1998-01-12
Abstract: A microwave frequency Doppler vehicle intruder alarm comprises an oscillator 3, a mixer 2 and an amplification stage 4, 5 having its output applied to a low-pass filter 7, whose output is split into two branches. A first branch, comprising a rectifier diode and a comparator, provides a signal on its output when a significant level of non-carrier microwave signals is received. This branch is sensitive to signals having Doppler frequencies of 0-200Hz, which includes the intruder indicative frequencies. A second branch, comprising an amplifier 8, a high pass filter 9, and a comparator 10, provides an output signal on the detection of a significant level of signals in the 40-200Hz band, which frequencies are indicative of externally generated interference. A logic element 15 mutes the output of the alarm when the second branch indicates the presence of externally generated interference. An antenna arrangement (Figure 3, not shown) generates a rectangular radiation field which provides optimum coverage of the interior of a vehicle by being mounted in the roof thereof. Steering of the radiation field to provide optimum illumination when the arrangement is mounted off-centre on the roof is achieved by the use of a shunt capacitor to effect a phase difference in signals applied to respective ones of first and second antennae.

Title: Power fet device
Inventor: JERRED PAUL ANTHONY
IPC: H01L29/78
Filed: 1998-06-26
Abstract: A power FET device comprising a semiconductor wafer substrate defining first and second surfaces, a gate electrode extending over the first surface of the substrate but insulated therefrom, and a drain electrode extending over the second surface of the substrate. The gate electrode defines a regular array of apertures. An FET body region of a first conductivity type is formed in the first surface of the substrate beneath each gate electrode aperture, each body region extending a first predetermined lateral distanc e from edges of the gate electrode defining the aperture. An FET source region of a second conductivity type is formed within the body region beneath each gate electrode aperture, each FET source region extending from the edges of the gate electrode defining the respective aperture a second predetermined lateral distance w hich is less than the first distance. A source electrode interconnects source contacts centrally located beneath each of the gate electrode apertures. An FET channel region is defined around the periphery of each source region. Pairs of adjacent gate electrode apertures define therebetween a strip of gate electrode the width of which varies along the length of the strip between a minimum which is substantially less than twice the first distance and a maximum which is substantially greater than twice the first distance. As a result, body dopant introduced through adjacent gate electrode apertures merges to form a single body structure extending continuously between the apertures beneath portions of the strip of gate electrode of minimum width.
