Patent GB-0129450-D0 (GB)
Title: Trenched semiconductor devices and their manufacture
IPC: H01L21/336
Filed: 2001-12-08
Abstract: In semiconductor devices which include an insulated trench electrode ( 11 ) in a trench ( 20 ), for example, trench-gate field effect power transistors and trenched Schottky diodes, a cavity ( 23 ) is provided between the bottom ( 25 ) of the trench electrode ( 11 ) and the bottom ( 27 ) of the trench ( 20 ) to reduce the dielectric coupling between the trench electrode ( 11 ) and the body portion at the bottom ( 27 ) of the trench in a compact manner. In power transistors, the reduction in dielectric coupling reduces switching power losses, and in Schottky diodes, it enables the trench width to be reduced.

Filed: 2003-04-25
Abstract: An anode for an X-ray source is formed in two parts, a main part and a collimating part. The main part has the target region formed on it. The two parts between them define an electron aperture through which electrons pass to reach the target region, and an X-ray aperture through which the X-rays produced at the target leave the anode. The anode produces at least the first stage of collimation of the X-ray beam produced.

Title: Method and apparatus for use in security
IPC: G06F21/57
Filed: 2003-09-11
Abstract: A security system for securing data paths in a network responds to events to change parameters of the security features in use. For example, it can change the type of encryption algorithm being used, or parameters of the encryption algorithm such as the key length or number of rounds of negotiation, or it can change a data transfer protocol. Events which the security system can respond to include user action, such as logging on to a more expensive service or moving their network location, or date or time, or patterns of usage in the network. The system processes incoming data using rules to determine a response. Parameters are changed by outputting configuration data to communication devices attached to the network, such as the head end and television receivers in a digital television system. In a preferred form of the system, the parameters of the security features in use can be dependent on network location, introducing diversity to the system which makes the security more difficult to penetrate.

Patent GB-8402251-D0 (GB)
Title: Reducing analog output current
IPC: H03M1/06
Filed: 1984-01-27
Abstract: An integrated circuit digital to analog converter includes circuitry having first and second resistors in a R/2R resistor ladder which scales bit current contributions to an analog output current. Each of the first and second resistors have a respective terminal connected to the collector of a bit current transistor, the emitter of which is connected to the emitter of a waste current transistor. The digital to analog converter includes a metal ground voltage conductor having a "shared node" and a distributed resistance between one side of the shared node and a main ground voltage connection. The collector of the waste current transistor and a second terminal of the first resistor are both connected directly to the shared node. In operation, the waste current transistor switches waste current into the shared node, rather than into a separate waste current ground conductor. This results in substantially less voltage variation across the distributed resistance of the metal ground voltage conductor, and consequently lower non-linearity, than is the case if waste current is switched into the separate ground conductor.
Patent GB-8523684-D0 (GB)
Title: Flow sensing device
IPC: G01F1/68
Filed: 1985-09-25
Abstract: A fluid flow sensing device comprises first and second p-n junctions (T.D). one (T) of which is arranged to be disposed in the fluid flow to be measured and the other of which is arranged to be disposed at a position such that its temperature depends only on that of the fluid. An amplifier (20) monitors the voltage drop across the first p-n junction. A comparator (16) compares the measured voltage drop across the first p-n junction with a reference level (V<sub>RE+2</sub>) to provide a feedback voltage (V<sub>c</sub>) which is used to control the heating of the first p-n junction such as to maintain the temperature of that junction constant irrespective of variations in the fluid flow or the fluid temperature. A current is passed through the second p-n junction and the voltage drop across it is monitored and compared with the feedback voltage (V<sub>c</sub>) to provide a signal which is a function of fluid flow alone.

Title: Polymers & their use as gels for electrophoresis
IPC: G01N27/26

Abstract: PCT No. PCT/EP88/00515 Sec. 371 Date Jan. 31, 1989 Sec. 102(e) Date Jan. 31, 1989 PCT Filed Jun. 10, 1988 PCT Pub. No. WO88/09981 PCT Pub. Date Dec. 15, 1988.A novel synthesis of N-acryloyl-tris-(hydroxymethyl)aminomethane (NAT) is described. The polymerization kinetics and transparency of the poly(NAT) gels crosslinked by a crosslinker (CL) e.g. N,N'-methylenebisacrylamide (Bis), i.e. poly(NAT+Bis) polymer, are shown. Poly(NAT+Bis) gradient (4-24%) gels were prepared and found to resolve native proteins according to their size. The exclusion limit of these gels is over 3x106 Da. This is more than threefold higher than the exclusion limit of the polyacrylamide gradient gel of the same concentration. Therefore poly(NAT+CL) gels are better than polyacrylamide gels for the resolution of large proteins. It was demonstrated that poly(NAT+CL)-polyacrylamide composite gels could be prepared. The poly(NAT+CL) gels were found to be advantageous also for isoelectric focussing in carrier ampholytes or immobilized pH gradients. Poly(NAT+CL) gels are also very good for separation of nucleic acids. The resolution is particularly good in the range between several hundred to 4-5000 base pairs. Under the optimized conditions, DNA molecules of more than 20 kbases can be perfectly resolved.

Title: Opto-electronic scale reading apparatus
IPC: G01D5/38
Filed: 1994-12-22
Abstract: An opto-electronic scale reading apparatus includes a reflective scale (410) relative to which a readhead is movable. The readhead includes a light source in the form of the emission end of an optical fibre (300), which directs light via collimating lens (420), beam splitter (310), and deflecting optics (312,314) onto the scale. The light reflected from the scale passes through an index grating (416) to generate a series of spatial fringes in the plane of an analyser (418). The analyser comprises a series of elongate light transmitting colour filters, extending substantially parallel to the fringes and arranged in a repeating pattern (e.g. red, blue, green, red, blue .....); like-coloured elements are separated by a distance corresponding to an integer multiple of the fringe pitch. The array (418) encodes the fringes into a plurality of phase-shifted signals, which pass through the beam splitter (310), lens (420) and back along fibre (300). A plurality of corresponding colour filters, provided at the other end of the fibre (300) deflect the relevant colour light onto individual photodetectors thereby to produce a plurality of cyclically modulating phase-shifted electrical signals, from which the relative displacement of the readhead and scale may be determined. Where the fibre is of plastics material the light is preferably in the infra-red spectrum to produce attenuation. <IMAGE>

Date Dec. 8, 1994The present invention provides a nasal drug delivery composition comprising nicotine or a pharmacologically-acceptable salt or derivative thereof wherein the composition is adapted to delivery a pulse of nicotine for rapid absorption and a controlled release of nicotine for subsequent sustained absorption. The controlled release phase can be achieved by providing an ion-exchange material which will form a complex with the nicotine. The ion-exchange material may be a polymeric material such as a polysaccharide, or may be in the form of bioadhesive ion-exchange microspheres. The pulse release can be achieved by overloading the ion-exchange material with nicotine so that the composition contains some excess nicotine for immediate release and absorption. Alternatively, some nicotine may be associated with a non ion-exchange material which will release the nicotine immediately on contact with the nasal mucosa, for example non-ion-exchange bioadhesive microspheres.
