Patent GB-2395077-A (GB)
Title: An amplifier arrangement linearised by predistortion and feedforward; adaptive bias for improved efficiency; thermal overload protection
Inventor: NEUHAUS MARTIN
IPC: H03F1/32
Filed: 2002-11-01
Abstract: An amplifier arrangement comprises a preamplifier 002 feeding a power amplifier 012. The distortion produced by the preamplifier 002 is isolated by summer 007 and this distortion signal is then added to the preamplifier output with appropriate phase and amplitude to provide a predistorted input signal suitable for the power amplifier 012. Residual distortion at the output of the power amplifier is removed by an adaptive feedforward loop 014-020. Amplifier efficiency may be improved by altering amplifier bias and supply voltage in dependence on the input signal (figure 10). Amplifier bias and attenuation of the input signal may be adjusted as a function of the signal power input integrated over time, the thermal capacity of the transistor junction, and the statistical probability of data occurrence in the modulated input signal. In particular, the input may be attenuated to prevent thermal overload.

Title: Coupling an expandable tubular member to a preexisting structure
Inventor: COOK ROBERT LANCE
IPC: B21D39/08
Filed: 2001-06-12
Abstract: An expandable tubular member 1435 is coupled to a wellbore casing 1400 by anchoring a packer 1450 to the wellbore casing 1400 so as to maintain an expansion cone 1440 in a stationary position. The tubular member 1435 is then lowered towards the stationary expansion cone 1440. As the lower end of the tubular member 1435 impacts the expansion cone 1440 it is radially expanded into contact with the wellbore casing 1400. The packer 1450 is then decoupled from the wellbore casing 1400 after which the expansion cone 1440 is axially displaced by applying an axial force to a first support member 1420. The axial displacement of the expansion cone 1440 radially expands the expandable tubular member 1435 into intimate contact with the walls of the wellbore casing 1400.

Title: Auxiliary content handling
Inventor: PAILA TONI
IPC: H04N5/44
Filed: 2004-11-09
Abstract: A broadcaster prepares primary content session stream data, and auxiliary content files, such as subtitle text. The auxiliary data may be provided using a two-level structure. Here, the first level can be is a file having plural entries each with a control information item, e.g. a timestamp, and a reference is found. A receiver at a time relating to a timestamp tenders video content from a packet 43 having that timestamp, and also renders subtitle text from the second level file 46 having the same reference as the reference corresponding to the timestamp in the first level file. Thus, the broadcaster defines when subtitle text strings are to be rendered but without requiring streaming of packets including the auxiliary data. This makes it easy for a receiver to synchronise the auxiliary data with the primary content. A single level file structure can be used instead.

Title: Method and apparatus for monitoring corrosion
Inventor: COTTIS ROBERT ALAN
IPC: G01N17/02
Filed: 2003-06-06
Abstract: A method and apparatus for monitoring the corrosion of a working electrode An alternating perturbation signal of at least one frequency is applied to the working electrode. A signal representing the response of the working electrode to the applied perturbation signal is monitored. The monitored signal is filtered to separate out a signal representing the response of the electrode to the or each applied frequency and an electrochemical noise output signal representative of corrosion of the working electrode. The potential of the working electrode relative to a reference electrode may be controlled by controlling the supply of current through an auxiliary electrode. The supplied current is then monitored and the monitored current is filtered. Alternatively, a known alternating current may be applied between the working electrode and an auxiliary electrode and fluctuations in the potential of the working electrode relative to a reference electrode may be monitored, the monitored potential being filtered. A measure of the impedance of the working electrode is derived from the applied perturbation signal and the response signal. Both electrochemical potential noise and electrochemical current noise measurements may be derived from the known applied potential and the measured current or the known applied current and the monitored potential.

Title: Furniture chocks
Inventor: BRODRICK-BARKER NIGEL CHARLWOO
IPC: A47B91/12
Filed: 2005-09-17
Abstract: A chock device 10 for supporting an item of furniture at the correct attitude comprises a body having a generally flat bottom surface and a channel 12 extending across its upper surface between opposite ends thereof. The channel 12 comprises generally parallel upstanding side walls 13 extending from opposite longitudinal side edges of the bottom wall 14, the bottom wall 14 increasing in thickness by 1-2mm away from opposite ends of the channel towards a point intermediate opposite ends of the channel 12. In use, the device is inserted under the lower side edge of a panel of the item of furniture, such that the panel extends through the channel 12 therein. The gradual increase in thickness of the bottom wall 14 of the chock device avoids the application of localised forces to the edge of the panel. Also, the side walls 13 of the channel 12 serve to constrain the panel and hide any unsightly deformations which may occur.

Title: A CMOS current-mode logic gate using subthreshold conduction
Inventor: TOUMAZOU CHRISTOFER
IPC: H03K19/003
Filed: 2005-10-27
Abstract: A low power CMOS CML logic gate comprises a differential transistor pair M1,M2 operating in weak inversion and switching current to either of a pair of load transistors M3,M4 also operating in weak inversion. The load transistors have short channels (90 nm) and so are subject to drain-induced barrier lowering (DIBL) which reduces output resistance in saturation (figure 5b). This allows the loads to operate linearly for source-drain voltages from zero to voltages above VDSsat so that a higher output logic swing can be obtained. The logic output swing may be stabilized against PVT variation by a bias circuit using a replica gate (figure 4).
