Patent GB-2396067-A (GB)
Title: Multiple bandwith amplifier control systems for mobile stations and methods therefor
Inventor: SCHWENT DALE GERARD
IPC: H03F3/189
Filed: 2002-04-18
Abstract: RF amplifier control circuits for transmitters in mobile communication devices, combinations thereof and methods therefor. The control circuits include generally proportional and integral control circuits having an output coupled to a control input of an amplifier (110). An initial control signal is applied to the amplifier before a vector modulator output (120) coupled an input thereof is at full output power. The vector modulator output is ramped to full output after applying the initial control signal. Thereafter, the initial control signal applied to the amplifier during ramping is corrected by integrating an output of the amplifier relative to a second reference signal with an integral control circuit coupled to the control input of the amplifier, the second reference signal is proportional to the ramping vector modulator output.

Title: Road safety barrier
Inventor: BOWYER STEVEN
IPC: E01F15/04
Filed: 2005-04-18
Abstract: A road safety barrier 22 comprises a series of beam sections 22a-22e together forming a length of barrier and supported above the ground by way of posts 24a-24g. The positions of successive posts along at least part of the length of the barrier shift relative to the centres of the beam sections. The shift may be progressive but uniform along a section thereof so that the flexibility of the barrier is substantially constant. Shifting the locations of the posts along the length of the barrier by an increasing or decreasing amount has the effect of increasing or decreasing the strength of the barrier so that different road conditions can be accommodated even though beam sections of constant length are used to construct the barrier.

Title: Monolithically integrated optoelectronic components
Inventor: PROSYK KELVIN
IPC: H01L27/15
Filed: 2006-03-23
Abstract: A monolithically integrated optoelectronic component comprises a substrate 48 and at least three optoelectronic sub-devices 41, 42, 43 integrated within a semiconductor layer on the substrate. Each of the sub-devices has an upper conductor 44 and a lower conductor 45, 46 separated by a common active region 49. Two sub-devices 41, 43 are electrically coupled to a conducting semiconductor sub-layer 47 within the semiconductor layer by their upper or lower conductors. Electrical isolation zones 54, 55, 57 are provided for electrically isolating a further one of the sub-devices 42 from the semiconductor sub-layer and the coupled conductors of the sub-devices, and for electrically isolating the other conductors of the sub-devices 41, 43 from one another. The combined use of such electrical isolation zones enables more complex electrical connection schemes to be used than has been possible with conventional integrated optoelectronic components. Such electrical connection schemes can be independent of the physical ordering of the sub-devices on the substrate which is of significance in terms of the optical path through the sub-devices.

Title: Determining hand-off in a multilayer CDMA cellular communication network
Inventor: FOSTER GERARD
IPC: H04W36/00
Filed: 2007-01-30
Abstract: A Code Division Multiple Access cellular communication system comprises a base station (101) supporting a remote station (117) making uplink transmissions using an uplink scrambling code in a first cell. A controller (119) determines a first set of uplink scrambling codes from an identity of the first remote station (117) and selects the used code therefrom.

Title: Apparatus for providing access to a controlled environment
Inventor: MELLOR CLIVE
IPC: F16J15/10
Filed: 2007-06-11
Abstract: A containment apparatus 1 comprises an access device 9 for providing contained access to a sealed enclosure 7. A vessel 5 and passive port 3 creates the sealed enclosure 7, which contains contaminated material. When access is required to the enclosure 7, the access device 9 is docked on to the passive port 3. When docked, an active port 11 of the access device 9 co-operates with the passive port 3 to open an access aperture 13 into the enclosure 7. An operator may then reach inside the enclosure 7 by inserting there hand in to a glove bag 15 and reaching through the access aperture 13. The glove bag 15 is sealed to the periphery of the active port 11. As such, the operator remains isolated from the enclosure. When access is no longer required, the operator may withdraw the glove bag 15 from the access aperture 13 and close the access aperture 13. Accordingly, the access device 9 may be transported and stored for re-use, or cleaned, or docked on to another enclosure for transferring materials, etc.

Title: Controlling timing of synchronization updates
Inventor: HATALA EDWARD
IPC: H04B1/16
Filed: 2007-06-22
Abstract: A femtocell basestation has a frequency synthesizer for generating signals with desired frequencies. A hold-over period is defined for the frequency synthesizer, based on an expected time that the crystal oscillator in the frequency synthesizer will take to fall outside a specified synchronization tolerance, in view of the result of crystal aging on its oscillation frequency. When the femtocell basestation synchronizes itself to a master device, it starts to monitor the elapsed time and, when this elapsed time exceeds the hold-over period, the femtocell basestation requests further synchronization data signals from the master device.

Title: Protective enclosure for bird feeder
Inventor: MINDELL BERTRAM
IPC: A01K31/06
Filed: 2008-04-29
Abstract: A protective enclosure for a wild bird feeder has apertures sized to selectively restrict access to its interior. Said enclosure comprises an outer mesh section 1 overlying an inner mesh section 2 loosely mutually connected by one or more link members 5 extending into a space therebetween.
