Title: An NMOS charge pump driver for an integrated high-side switch
Inventor: FINNEY ADRIAN
IPC: H03K17/06
Filed: 2003-07-31
Abstract: A driver for a voltage-boosting charge pump in an integrated high-side switch comprises a totem-pole pair of NMOS transistors 20,21 driven by complementary signals 16,17 from low voltage oscillator 15. The drain of the upper NMOS transistor 20 may be common with the drain of the high-side output power transistor (7, figure 2), thereby permitting simple cointegration. High voltage lateral transistors are not required. The voltage of the oscillator's power supply 18 may be lower than the supply voltage at the drain of the upper drive transistor 20. A voltage boosting circuit may be inserted in line 16. The output power device may be a MOSFET or an IBGT. The high-side switch may be used in vehicles.

Title: Optimisation of sequential combinatorial processes utilising a surrogate model
Inventor: OLSEN TOR-MORTEN OVERBY
IPC: G06Q10/04
Filed: 2003-09-12
Abstract: A method of optimising a sequential combinatorial process comprising an interchangeable sequence of events comprises using a master model to model a selection of the possible sequences, and using information derived from the master model in a surrogate model that approximates the master model with a much shorter computation time. The surrogate model calculates all the possible sequences using an algorithm to select from the information calculated by the master model that which most closely matches the events of a present sequence, following a prioritised system so that the best match is used wherever possible. All results from the surrogate model are compared so that the modelled sequence that gives the result closest to a desired optimum result for the process can be identified, and potentially applied to the process. Accuracy can be enhanced by running the optimum sequence through the master model as a check, and further by adding the optimum sequence to the information used by the surrogate model in future calculations. The model can be applied to welding sequences in manufacturing.

Title: Combined microwave and infrared sensor
Inventor: TSUJI MASATOSHI
IPC: G08B13/16
Filed: 2003-12-22
Abstract: A combined sensor is disclosed capable of detecting objects only within a desired detection area even in the event of an error in the sensor mounting angle. The combined sensor comprises a dual frequency microwave sensor 3 and a passive infrared (PIR) sensor 4. The microwave sensor 3 provides object detection based on the phase difference between IF signals after mixing of the transmitted and reflected signals whilst the infrared sensor provides object detection based on received infrared radiation from an object in the detection area and an alarm is issued if an object is detected by both sensors. The frequency difference between two microwaves transmitted by the microwave sensor 3 is such that the phase difference between the IF signals is approximately 180 degrees when there is an object at the intermediate distance between the maximum detection distance within the target detection area and the maximum detection distance in the event of a deviation of the detection area due to incorrect mounting of the infrared sensor 4.

Title: Subsea structure and methods of construction and installation thereof
Inventor: MIORCEC DE KERDANET TEGWEN BER
IPC: E21B17/01
Filed: 2003-11-25
Abstract: A structure (200) for subsea installation has buoyancy distributed substantially along its length in order to float said structure in horizontal orientation to a point of installation. When said structure is upended, said distributed buoyancy maintains said structure in a substantially vertical orientation and operational state, without the need for further, non-distributed buoyancy (for example, without substantial tension being provided by a top buoy or surface vessel (100)). The structure may comprise a flexible or rigid riser conduit for hydrocarbons. Buoyancy modules may be fixed with spaces between them, for example to achieve a structure similar to a SLOR, or COR, but without a top buoy. The buoyancy modules may alternatively be free to slide longitudinally along the structure, so as to impart their buoyancy force through one another to the top of the structure.

Title: Radio Link Handover in a Cellular Communication System.
Inventor: RANDALL PETER P
IPC: H04W36/38
Filed: 2005-09-06
Abstract: A base station (109) of a cellular communication system (100) comprises an RNC interface (301) which receives a radio link handover initiation message for a radio link from a radio network controller (113). A switch delay processor (309) determines a handover switch delay and a characteristics processor (311) sets a characteristic of a radio link handover acknowledge message in response to the handover switch delay. A message generator (313) generates a radio link handover acknowledge message and transmits this to the radio network controller (113). The radio network controller (113) comprises an RNC handover controller (125) which determines a radio link handover switch time in response to the characteristic. A better timing of the radio link handover may be achieved. The invention may e.g. be applicable to an HSDPA (High Speed Downlink Packet Access) service of a UMTS (Universal Mobile Telecommunication System) cellular communication system and may reduce the amount of data discarded from buffers during an HSDPA handover.
