Patent GB-2416604-A (GB)
Title: Valve
Inventor: BRAMLEY HUGH CHRISTOPHER
IPC: F15B21/08
Filed: 2004-04-30
Abstract: A fluid flow control valve island (9), for example for use in sequentially controlling pneumatic actuators of automated production machinery, comprises a plurality of sets (one of which is designated 14) of four bistable 2/2 control valves a, b, c and d, a programmable controller (10) which processes control signals from an external programmable logic controller (PLC) (11), and a memory element (13). The controller (10) is pre-programmed with a program downloaded from an external PC (12) and stored in the memory element (13), the program identifying the respective predetermined valve type to be simulated by each set of 2/2 valves a, b, c and d. The controller (10) generates from signals from the PLC (11) respective outputs to each of the four valves a, b, c and d in a set so as to actuate one or more of those four valves and thus switch that set from one mode of the predetermined valve type simulated to its other, or another, mode. The invention thus provides a universal valve island that may be programmed by the manufacturer or the user to simulate a multitude of selected, differing, valve types, including 2/2 NO or NC, 3/2 NO or NC, 5/2, 5/3 COP, 5/3 COE and 5/3 APB types without having to mechanically reconfigure the valves on the island (9).

Title: A transimpedance photo-receiver with voltage supply self-regulation
Inventor: KWA HOCK TIONG
IPC: H04B10/06
Filed: 2006-03-10
Abstract: A transimpedance amplifier for amplifying signals in an opto-coupler, infra-red receiver, ambient light sensor, proximity sensor or optical disc reader comprises three amplifying stages M1,M2, M3 with feedback through an RC network. The amplifier is biased by current source Itop and the voltage on rail SBIAS is regulated by the action of M0,M101, M2 and other transistors. If the voltage on the rail SBIAS rises the voltage on the node Vbias follows it and the currents in M101, M2 and other transistors increase, thereby sinking more current from the node SBIAS and restoring the voltage at that node. No separate regulator is required and current previously consumed in a shunt regulator instead passes through the amplifier so that power saving, speed improvements or both advantages may be obtained. Low voltage operation is possible.

Title: Method and apparatus for identifying changes in a road map
Inventor: GOTO MASAYUKI
IPC: G08G1/01
Filed: 2006-08-02
Abstract: A method of identifying changes in a road map comprises the steps of collecting position data for two different time periods from vehicles equipped with individual terminals (s1), drawing distribution maps for each time period (S2 and S3) (Figs 7a and 7b) and producing a differential distribution map (S4)(Fig 8) by comparing the two. The differential map is then analyzed to identify changes between the two maps (Fig 6a-6b). A change in the road map is then determined if the differential distribution satisfies a predetermined condition (S5) and the road map is updated. A change, such as a new road, is determined when a differential distribution is absent from the first map but is presenting the second map (Fig 6c). A closed road is identified when a distribution is present in the first map but not in the second map (Fig 6d).

Title: Fluid turbine with secondary turbine driven by induced flow
Inventor: STEIN UWE BERNHARD PASCAL
IPC: F03B13/26
Filed: 2007-01-04
Abstract: A fluid turbine for use in a tidal stream 8 has turbine blades 4 comprising conduits 5. A secondary flow is induced as fluid is drawn into a low pressure region at the surface of the blade 4, and also due to centrifugal force. The secondary flow drives a second turbine 12 at a relatively high speed, and so reduces the torque applied to the gearbox 15. This system addresses the problem of very high shaft torques from the primary turbine 4.

Title: Interpreting well test measurements
Inventor: ZHAN LANG
IPC: G06F19/00
Filed: 2007-06-08
Abstract: Based on measurements that are obtained from a well test (e.g. closed chamber testing (CCT) system), a pressure in the well is modeled as a function of at least a skin effect factor that varies with time. The results of the modeling may be used to estimate at least one well parameter, such as a formation parameter and/or a well pressure, as examples. The performance of the test in the well may include closing off a surge chamber in response to a downhole parameter measured in connection with the test. Modeling the pressure may also include determining a sandface flow rate history associated with the test and generating a model flow rate which corresponds to the sandface flow rate history. The invention can be applied to a conventional well test or drill stem test (DST) where the production at the surface may be constant but the skin effect factor varies.

Title: Error correction in data communication system using iterative belief propagation with syndrome sent over a separate channel
Inventor: HARRISON KEITH ALEXANDER
IPC: H03M13/13
Filed: 2007-10-31
Abstract: To enable error correction of subject data (m) sent over a noisy first channel (40) between transmitting and receiving apparatus (20, 30), a target syndrome (s) determined as an ordered plurality of modulo-2 summations of the bit values of respective predetermined selections of bits of the subject data (m) is also sent but over an error-free or error-corrected second channel (45). At receiving apparatus (30) the errored received subject data (r) is error corrected by applying iterative belief propagation to adjust bit-value probabilities of the received subject data (r) such that an ordered plurality of modulo-2 summations of the probable bit values of the respective predetermined selections of bits matches the received target syndrome (s). Preferably, the bit selections for the modulo-2 summations are determined in accordance with a logical network independently generated in a pseudo-random manner in the transmitting and receiving apparatus (20, 30). LDPC codes are used. Applications include quantum key distribution (QKD).
