Title: Reducing transmission power in response to a detected decrease in available battery power
Inventor: APPLETON IAN KENNETH
IPC: H03G3/00
Filed: 2001-05-22
Abstract: A mobile communication device, which may be a mobile telephone, comprising means to detect a reduction in the available battery power by detecting a corresponding reduction in its transmit power. In response, if a reduction is detected, the device sets its transmit power to a reduced second level which will take less current from the battery and therefore prolong the life of the battery. Furthermore this process may be repeated and the transmit power may be reduced in steps of about 2 dB to lower the transmit power level each time a further reduction in the available battery power is detected. To detect the reducing transmit power the device may monitor a feedback signal 21 from the transmitter 19 and use a comparator 15 to determine a reduction in the transmit power. The device may also comprise means to deny a request from an external system to increase the transmit power. The device may also provide a visual or audio alert that the transmit power has been set to a lower level.

Title: Network bandwidth optimization by dynamic channel allocation
Inventor: GOODE CHRISTOPHER
IPC: H04N7/173
Filed: 2000-04-19
Abstract: An information delivery system provides programming, such as video programming, by dynamically allocating the programming to channel slots, based on the availability of the channel slots. Programming with high viewership statistics is transmitted substantially continuously and programming with lower viewership statistics is transmitted "on-demand" in response to requests by users by way of a subscriber station. The subscriber stations maintain a map, provided by a corresponding session control manager, of currently available and currently transmitted channels. The information delivery system, in a preferred embodiment, takes the form of a Hybrid Fiber Coaxial (HFC) system.

Title: Vehicle switching system control by external sensor
Inventor: TURNER MURRY
IPC: G05D1/02
Filed: 2001-12-19
Abstract: An onboard system for switching a vehicle parameter to a pre-programmed value in response to a sensed external stimulus comprises a sensor 2 and a processor 32. The sensor 2 detects remote emitters of electromagnetic radiation such as infrared zone markers (40, see fig 5) in a warehouse, and may be mounted on top of the cab 9 of a forklift truck 6. Alternatively, the vehicle 6 may have a radiation source, emitting polarised light, for example, so that reflections from the environment or from bar codes may be received by the sensor 2. On receipt of a signal from the sensor 2, the processor 32 sets a parameter affecting engine speed, acceleration, deceleration, direction, tilt speed, lift speed, steering sensitivity or a combination of performance parameters. The system may also be configured to vary the gearing of a hydrostatic transmission by controlling the angle   a   of a swash plate 16.

Title: An ion mobility spectrometer coupled to a scanning mass filter and fragmentation cell
Inventor: HOYES JOHN BRIAN
IPC: H01J49/42
Filed: 2002-09-23
Abstract: Mass spectrometry wherein ions having a particular desired charge state, e.g. multiply charged ions, are selected by operating an ion mobility spectrometer 4, preferably an ion tunnel IMS, in combination with a quadrupole mass filter 5. Selected ions may be fragmented or reacted to form daughter ions or product ions in a collision cell ion trap 6, and the sent back upstream to an upstream ion trap 2. The fragment or product ions are then passed through the IMS where they are temporally separated according to their ion mobility, and then re-trapped in the collision cell ion trap 6 before being released therefrom in packets. Energisation of a pusher electrode 8 of an orthogonal acceleration time-of-flight mass spectrometer (oaTOF-MS) is synchronised with the release of the ion packets from the trap 6, so as to mass analyze the fragment or product ions with a near 100% duty cycle across the whole mass range.

Title: Actuator control providing linear and continuous force
Inventor: BRAUN ADAM C
IPC: G06F3/038
Filed: 2000-05-10
Abstract: A method for controlling an actuator to compensate for a non-linear output of an actuator includes determining a desired command current for the actuator, where the command current causes a desired output force to be output by the actuator. The desired command current is correlated with an approximated point of a characterization curve of the actuator, where the characterization curve includes multiple points determined in a previously performed characterization of the actuator. The approximated point is determined between two successive points of the multiple points using a linear approximation, and a required command duty cycle is determined from the approximated point of characterization curve. A drive signal having the determined command duty cycle is applied to the actuator to cause the actuator to output the desired force.
