Abstract: In a digital satellite television system in which a television receives its signal via a receiver/decoder, such as a set top box, interactive applications can be downloaded and run on the receiver/decoder. The application code is arranged as modules, and the downloading of modules is preceded by searching a directory module within a specified local address. The modules are signed and the directory module is signed and encrypted so that a single encryption applies to all of the modules making up the application. Multiple public encryption keys are stored in ROM in the receiver/decoder, so that applications can be created by different sources, without the sources needing to know each other's private encryption keys. A facility is provided to enable an encryption key to be temporarily stored in RAM in the receiver/decoder, so that a manufacturer of the receiver/decoder can check its functionality. A signature of the directory may be hidden at a variable position in a block of dummy data in the directory module. An application to be downloaded may be checked against an application validation bitmap stored in the receiver/decoder. <IMAGE>

Title: Liquid crystal displays with post spacers, and their manufacture
IPC: G03F1/00
Filed: 2002-12-14
Abstract: A post spacer ( 25 ) for a liquid crystal cell ( 26 ) is formed using colour filter material. At least a portion ( 15 a) of the post spacer ( 25 ) and a corresponding pixel colour filter ( 15 b) are defined from a layer of colour filter material ( 15 ) using photolithography, in which a photomask ( 8 ) comprising a pattern of transparent, half-tone and opaque regions is used to define structures with two different thicknesses t 1, t 2 simultaneously. The use of a half-tone photomask ( 8 ) allows the thickness of the post spacer portion ( 15 a), and, therefore, the eventual height of the post spacer ( 25 ), to be defined independently of the thickness of the colour filter ( 15 b). The post spacer ( 25 ) may be formed using half-tone photomasks ( 8 ) to define more than one layer of colour filter material ( 15, 23 ), allowing the ratio t 1 /t 2 to remain within a predetermined limit. The post spacers ( 25 ) are preferably located away from thin film transistors (TFTs) ( 31 ) and at intersections of row and column electrodes ( 32, 33 ).

Title: Electric stock control and auditing of detonator use
IPC: G06Q10/08
Filed: 2004-08-09
Abstract: A system for recording the use of individually identifiable detonators is described, the system comprising a data log of identified detonators; means to record electronically when a detonator is committed to fire; means to alter the data log to log as consumed a detonator recorded as so committed. A detonator is recorded as committed to fire only either when a detonator is intrinsically and irrevocably committed to fire or when an abort facility is set up in such manner that the system operates to remove the log entry of detonator consumption in the event that an abort signal is given. A method of recording the use of individually identifiable detonators is also described.

Title: Apparatus and method of signal amplification
IPC: H04B1/04
Filed: 2004-08-18
Abstract: There is disclosed a signal amplifier apparatus (1) with multiple signal channels (2) and a multiplicity of pre-transmission signal amplifiers (6) each one of which, when idle, is made available to and adapted for use by any of the signal channels requiring it. An allocating means (3) intermediate the signal channel sources (2) and the amplifiers (6) monitors signal amplifiers and allocates idle amplifiers to signal channels requiring amplification. Characteristics of the allocated amplifier (e.g. frequency response) are adjusted, if required, to adapt to the needs of the channel to which the amplifier is allocated. In this way, signal channels are not restricted to a single dedicated pre-transmission signal amplifier and may employ any idle one of the multiplicity of amplifiers as and when available. This adaptive sharing of a limited number of amplifiers effectively reduces the time a given signal, upon a signal transmission channel, is required to queue awaiting transmission. The apparatus is suitable for use in the HF and UHF bands.

Title: Method and apparatus for transmitting uplink signalling information
IPC: H04L12/56
Filed: 2005-05-03
Abstract: A User Equipment, UE, of a cellular communication system transmits scheduling assistance data to a base station comprising a base station scheduler which schedules uplink packet data. The scheduling assistance data relates to uplink packet data transmission from the UE. The UE comprises a channel controller which is operable to cause the scheduling assistance data to be transmitted from the UE to the base station in a first physical resource of an uplink air interface. The first physical resource is not managed by the base station based scheduler. The scheduling assistance data may specifically be transmitted in a first transport channel multiplexed with other transport channels on a physical resource. The transport channels may be individually optimized and may have different termination points and transmission reliabilities. Specifically, the transport channel supporting the scheduling assistance data signaling may have a high reliability and be terminated in the base station.

Patent GB-0706663-D0 (GB)
Title: Analysis of parallel manipulators
Filed: 2007-04-04
Abstract: A method of determining the positions and orientations of the base (8) and platform (10) of a parallel manipulator using an iterative calculation in which successive iterations calculate estimates of said positions and orientations, each estimate being determined from the previous estimate using an inverse of a derivative of an error function (F), that function also being used to determine error values for each estimate, wherein if the error values are deemed unacceptable a new derivative is calculated and the iteration is repeated, whereas if the error values are deemed acceptable the same derivative is used in a subsequent iteration. Thus the derivative need not be re-calculate for each iteration, whereby the process can operate more rapidly, e.g. in real time.

Patent GB-8824793-D0 (GB)
Title: Method & apparatus for processing electrical signals
IPC: G01H1/00
Filed: 1988-10-22
Abstract: An apparatus (10) for processing acoustic emissions or stress waves in order to recognise features indicative of variations in the process producing the acoustic emissions comprises a transducer (12) acoustically coupled to a machine or industrial process and arranged to detect the acoustic emissions and produce an electrical signal. The electrical signal is amplified by an amplifier (14) and the mean level of the electrical signal is measured by a mean level detector (18) and the minimum level of the electrical signal is measured by a minimum level detector (20). A ratio measurer (22) measures the ratio of the mean level of the electrical signal to the minimum level of the electrical signal. This method is self compensating for variations in the operating conditions of the machine or industrial process, is not significantly affected by electromagnetic switching transients, and can cope with very high numbers of transient excursions.
Patent GB-8827333-D0 (GB)
Title: Improvements in/relating to powder flow control valves
IPC: B65G53/22
Filed: 1988-11-23
Abstract: The disclosure relates to a powder flow control valve comprising a nozzle (33) formed from a material such as high density polythene having an upper frusto-conical section (33a) which converges towards the lower end of the nozzle and terminates in a cylindrical section (33b). The nozzle is encircled by a plenum chamber (24) to which sources of vacuum and air pressure are selectively connectable through a pneumatic control system (14). When vacuum is connected to the plenum chamber, the resulting pressure drop across the wall of the porous nozzle causes powder flowing through the nozzle to consolidate in the nozzle and terminate the flow. When air pressure is applied to the plenum chamber, the resulting pressure rise across the boundary surface accelerates powder flow through the nozzle. The control means is arranged to establish air pressure in the plenum chamber to initiate opening of the valve and flow through the valve and, after a pre-determined time, to terminate the air pressure supply and allow powder to flow under gravity through the nozzle before flow is terminated when a pre-determined quantity of powder has been delivered by the nozzle by applying vacuum to the plenum chamber.
