Title: Flow-operated valve
Inventor: ESLINGER DAVID M
IPC: E21B43/26
Filed: 2001-11-21
Abstract: A downhole tool 22 comprises a seal assembly 28, 30 and a valve 26 activated by an increase in fluid pressure. The seal assembly may be a straddle packer defining an isolated zone 32 in the wellbore which encloses a fluid outlet 24. The fluid may be fracturing fluid. The valve 26 is downhole from the seal assembly and biassed in an open position by a spring 116 or reference fluid chamber 122. An increase in fluid pressure through a flow restrictor (108, figure 2B) closes the valve, which may be a poppet valve 118. When pressure is reduced, the valve reopens and fluid flows from the valve into the wellbore below. Unwanted closing of the valve due to fluid free fall is prevented by a second flow restrictor (200, figure 2A). Should the valve become stuck in a closed position, fluid can be pumped through bypass channels 29 in the seal assembly and into the valve via outlet ports 120.

Title: Location data validation by static entities receiving location data items by short-range communication
Inventor: SPRATT MICHAEL PETER
IPC: H04L12/56
Filed: 2002-01-25
Abstract: A static but movable device (20S) has a short-range wireless transceiver (21) by which it can receive location data items (27). These items are usable by a location-data processing arrangement (22,26D) of the device to derive an estimate of the current location of the device. If the device (20S) is moved to another location, this estimate will cease to be valid. Accordingly, the device is provided with a move detection arrangement (34-38) for detecting indications that the device (20S) may have been moved, these indications being used by a location-validity supervisor (22,32) to determine whether or not the current location estimate is to be treated as still valid.

Title: Registering an application program of a mobile information device
Inventor: SHIPTON MARK
IPC: H04M1/72406
Filed: 2003-10-03
Abstract: An application program, e.g. Java (RTM), on a mobile wireless information device runs a self registration process when executed 305. The registration takes the form of a wireless transmission of registration data 340 from the device to a remote registration server for storage. The transmission may be an SMS text message and the registration data may include a program identifier, a device identifier and a registration server identifier. The device user may be prompted to authorise the transmission 330, and if denied, the program either quits or repeats a request for registration transmission 335. The registration data may also be stored on a memory element of the device 310 for reference when the program is again executed. The invention allows the application developer to monitor use of their software, the device user to be informed of modifications/updates and allows automatic optimisation of the device.

Patent GB-2412823-A (GB)
Title: Path setup using ACK message but not NACK message
Inventor: DE VEGA RODRIGO MIGUEL
IPC: H04Q11/00
Filed: 2004-03-31
Abstract: Connection set-up times may be optimised where a first node (1) sends a request to e.g. a central network controller (7) for a communication path to be set up to a second node (2). If sufficient resources are available to satisfy the request the path is set up and an acknowledgment (ACK) message (10) is sent to the first node. However if insufficient resources exist, a negative acknowledgment (NACK) message (11, fig.2b, not shown) is not sent to the first node. This avoids the first node having to continually resend the setup request in response to one or more received NACK messages, thereby decreasing the amount of traffic on the network. The first node may implement a queuing system whilst waiting for the ACK message to be received.
Patent GB-2416939-A (GB)
Title: A CMOS logic element wherein the dynamic pull-up current is supplied by an unregulated power rail
Inventor: BANKS TONY
IPC: H03K19/0185
Filed: 2004-08-02
Abstract: The output stage of a clocked CMOS logic element comprises pull-up transistors 30 and 38 connected to regulated and unregulated supply rails 34 and 40 at 1.5 volts and 3.6 volts respectively. Device 38 is enabled to provide pull-up current during a positive output transition and is then turned off by the control circuit 42 when the output node 28 attains a voltage near the regulated voltage 34. The provision of a large part of the dynamic current requirement directly from the battery improves overall efficiency, which is of benefit in mobile phones. The dynamic power is supplied directly from the battery and so no conversion losses are incurred in reducing the voltage to a lower level. The complexity, size and cost of the power supply is reduced because the regulated power supply is no longer required to provide large dynamic currents.

Abstract: A vertical metal/oxide/semiconductor (MOS) device such as a MOS-type field effect transistor (MOSFET) or insulated gate bipolar transistor (IGBT) has a breakdown-voltage sustaining layer 12 above a layer with low electrical resistance 11, the breakdown-voltage sustaining layer comprising at least one semiconductor region of a first conductivity type and a well region 13 in the surface of the breakdown-voltage sustaining layer. Guard rings (g1-g14, Fig. 13) having the same conductivity type as the well region surround the well region, and the spacing between the well region and the innermost guard ring is 1 micron or narrower. The device may have surface regions (14, Fig. 2) of the first conductivity type which are extended portions of the breakdown-voltage sustaining layer 12, surrounded by the well region 13. The surface area ratio of the surface regions to the well region may be in the region 0.01-0.2 and the surface region may be stripe-shaped. The devices have a high breakdown voltage and low on-resistance, minimising the trade-off relationship between the on-resistance and the breakdown voltage, enabling a high switching speed.
