Title: Uplink status flag (USF) detection for GPRS
Inventor: MA MING
IPC: H04W72/04
Filed: 2004-08-04
Abstract: For packet based data transmissions, a base station transmits an uplink status flag (USF) to a mobile station, which USF determines whether or not the mobile station may send data in one or more uplink timeslots. In the detection methods, a mobile node is assigned an USF and detects the presence of the USF in subsequent signal bursts transmitted to the mobile node. For the GPRS coding schemes CS2-CS4, the USF detection method comprises correlating the received USF samples with a plurality of possible USFs stored at the mobile node with the correlation weighted in favour of the assigned USF. False detection of the assigned USF can be minimised by checking the unscaled correlation value against a predetermined threshold. For the GPRS coding scheme CS1, for which there is no USF pre-coding, the received USF is decoded by the mobile node to provide an indication of decision confidence and the USF detection is rejected if the decision confidence is below a threshold. The path metric value is used to minimise false detection.

Title: Pressure relief valve
Inventor: KUGELEV VLADIMIR
IPC: F16K17/02
Filed: 2004-10-22
Abstract: A pressure relief valve <B>11</B> has a housing <B>13</B> fluidly connected to a pressurized system line <B>19</B> carrying a system fluid. The housing <B>13</B> carries a moveable piston <B>45</B> and a valve member <B>25</B> that both move between closed and open positions. The piston defines an upper chamber <B>47</B> and a lower chamber <B>49</B> within the housing. A pressurized fluid is supplied to the upper chamber <B>47</B> to bias the piston toward the closed position. After the relief valve opens from excessive system pressure, the pressurized fluid is injected into the lower chamber <B>49</B> via injector stab <B>57</B> to delay the return of the piston <B>45</B> to the closed position. Initially, the fluid in the lower chamber <B>49</B> flows through a check valve <B>53</B> while the piston <B>45</B> returns to the closed position. Then the fluid vent <B>75</B> in the lower chamber vents from the lower chamber <B>49</B> as the piston <B>45</B> and valve member <B>25</B> approach the closed position.

Title: A method and system for stabilizing operation of laser sources
Inventor: LUPO SILVIO
IPC: H01S3/131
Filed: 2005-11-01
Abstract: A system for stabilizing an output optical power from a laser source (1) against drifts induced by temperature and/or aging. The output optical power including a target optical modulation amplitude around a target average value. There is a power sensor (2) for sensing the output optical power from the laser source (1) and generating a power sensing signal (3) indicative thereof. A controller (5) sensitive to the power sensing signal is configured for selectively adjusting (6, 7) the bias (IB) and modulation (IM) currents of the laser source (1). This is achieved by detecting an error between the actual average output optical power from the laser source (1) and the target average value, and comparing the error against a given error threshold. When the error reaches the threshold, adjustment of the bias (IB) and modulation (IM) currents takes place to bring the output optical power from the laser source (1) back to said target average value (Ptarget) and said target optical modulation amplitude (OMAtarget) around said target average value (Ptarget).

Abstract: A device for product promotion comprises an upright tank 2 of transparent material to support a column of water, a means 10 at the lower end 3 of the tank 2 for generating a stream of air bubbles 29 which will rise upwardly, a plurality of individual vessels 5 immersed within the fluid, means 18, 19 to maintain the vessels 5 in an upright disposition, and each vessel 5 having a hole 15 for the entry of the water and air to a cavity 45 within the vessel 5. Each vessel also incorporates a float valve 24, movable between open and closed positions in accordance with the level of fluid within the cavity 45 of the vessel 5 to change the buoyancy of the vessel 5, such that, with a negative buoyancy vessel 5 is located at the lower end of the tank and with the valve 24 in a closed position, a number of bubbles enter and are trapped within the cavity 45 creating a positive buoyancy vessel which rises until at the upper end 30 of the tank. The progressively decreasing level of fluid within the cavity 45 eventually causes the float valve 24 to open to release at least some of the air bubbles 29 trapped in the cavity 45, thereby destroying the positive buoyancy such that the vessel sinks and the float valve is closed.
