Title: A switch mode amplifier in which a plurality of switched outputs are summed to drive a load
Inventor: LEEDHAM ROBERT
IPC: H03F3/217
Filed: 2000-03-31
Abstract: A switch-mode power amplifier circuit using high power, low distortion waveforms is connected to an electromagnetic load to provide a high degree of control over the load. The circuit comprising a plurality of half-bridge networks having outputs combined at a summation point. The half-bridge networks are switched to provide power outputs sequenced to generate an interlaced output at the summation point which is operably connected to the load so that for a given switching frequency of the networks the operational frequency of the circuit is increased. The sequencing of the half-bridge outputs to generate an interlaced output facilitates the reduction of the switching frequency of individual switching components within the half-bridges while at least maintaining the overall operational frequency of the circuit. For <I>N</I> half-bridges operating at <I>f</I> kHz, the overall operational frequency of the circuit is <I>Nf</I>kHz. Alternatively, the switching frequency of individual switching elements of a system operating at <I>f</I><SB>o</SB>kHz may be reduced by a factor of <I>N</I>. A feedback signal generated across the load is included at the summation point and is optionally augmented to decrease distortion.

Filed: 1998-08-28
Abstract: A digital signal processor has ALUs 58, 72 and accumulating registers 64, 66, 76 and 78 small in bit number, and g-bit guard bits are then added to the high order bits of the data, using bit alignments 32, 34 and guard bit adder 38, each implemented with a wiring. Pre-multiplied, 2N data, 46, is also converted to N+r+g-bit data, using bit alignment/guard bit adder 50. The N+r+g-bit data is selectively operated by means of parallel accumulators 58, 64 and 66 and 72, 76 and 78, and then selectively rounded and/or saturated by rounding/saturation processor. Bit alignment units 32, 82, 34 and 84 enable fixed-point and integer arithmetic to be performed. Addition/subtraction arithmetic operations which include scaling can be performed by employing barrel shifter 60 in parallel with the accumulators; feedback loops are provided between the accumulating registers 64, 66, 76 and 78 in which the outputs of the ALUs 58, 72 and the barrel shifter 60 are temporarily stored, and the inputs to the ALUs and barrel shifter. These latter features are claimed.

Title: Control of power transmission line
Inventor: FOLEY IAN DAVID
IPC: H02H11/00
Filed: 2000-07-14
Abstract: A power transmission line control enables loads connected between the live and neutral conductors 2,4 to be reconnected to a power supply following the occurrence of a short circuit on the line, without the need to first repair the short circuited section of the line. The power line comprises a plurality of locations each having a Signalling Power Management System (SPMS) unit 10 and a location transformer 12. The unit 10 comprises an impedance 18, which impedance and the location transformer 12 form a potential divider across the power supply. By comparing the voltages across the impedance 18 and transformer 12 following a disconnection, a controller 28 determines whether there is a short circuit on the section of the power line downstream from the location transformer 12 as far as the next SPMS unit. Only if there is no short circuit on this section does the controller 28 close a relay 26 in parallel with the impedance 18 such that all of the power supply voltage is dropped across the transformer 12. The line may supply railway track signals and points.

Title: Paging area optimisation in cellular communications networks
Inventor: HOPKINSON JONATHAN NEIL
IPC: H04W68/00
Filed: 2001-08-29
Abstract: An automated process for allocating groups of cells 1, 2, 3, 4 to specific location areas is adapted to analyse communications traffic within said cells, associate penalty values reflecting the penalty of particular cell pairs being grouped into the same location area and assign cells to common location areas so as to mimimise a sum of the penalty values. The magnitude of a penalty value is dependant upon the paging load of a particular cell and on the relative degree of coverage overlap between two particular cell pairs. The invention is advantageous in that it does not require any skilled, manual input. It can be applied to cellular communications systems such as GSM, UMTS and IS95.

Title: A torque converter with lock-clutch that is engaged when negative powertrain output occurs
Inventor: O'NEIL BRIAN MICHAEL
IPC: G06F7/00
Filed: 2001-09-13
Abstract: A controller, eg a proportional integral (PI) controller having encoded computer code, determines, when a lock-up clutch is disengaged, whether a torque converter output speed is greater than the torque converter input speed, such a situation represents a change from positive powertrain output to negative powertrain output (eg deceleration) and when this situation arises the lock-up clutch is engaged. Also the controller detects the lock-up clutch over-running (eg slipping) when a current gear is selected in a transmission 15 and adjusts an engine 10 operating parameter to maintain transmission input speed at or below a synchronous transmission input speed that is obtained, for example, from a look-up-table. Various different routines are disclosed, for example one routine determines whether a negative engine output torque is desired by detecting if an accelerator pedal is in a closed or tip-out position and selects a desired engine speed that is equal to a synchronous speed in a future gear ratio, thereby reducing transmission gear clunk. The engine may be controlled in a closed and/or an open loop fashion and the operating parameters include air/fuel, ignition timing, throttle angle etc. The torque converter 11 connects the transmission 15, via shafts 13, 17, to the engine 10.
