Title: Optimising target bit rate for wireless transmission of multiple video streams
Inventor: CHUNG-HOW JAMES
IPC: H04N7/24
Filed: 2010-06-22
Abstract: A method of controlling data transfer in a multichannel wireless video system which comprises a plurality of video data sources, a transmitter operable to transmit video data from the video data sources over an air interface, a plurality of client receivers operable to receive transmitted video data, the method comprising estimating available channel capacity for each client receiver 52, using parameters relating to the air interface, and using information relating queuing of video data in the video data sources; determining a target bit transmit rate for each client receiver 62 in dependence upon the estimated channel capacity, a quality parameter 54, and an activity parameter 56 for the client receiver concerned; and controlling the video data sources and transmitter in dependence upon the determined bit transmit rates. The channel capacity for each client is the capacity if each client were to utilize 100% of available channel capacity. The quality parameter 58 may relate to picture quality such as resolution and clarity and the activity parameter 60 may be generated from motion level, image texture detail and frame statistics.

Title: Hand tool aid
Inventor: LEWIS STEWART SEAN
IPC: B25B23/16
Filed: 2010-06-24
Abstract: The aid includes a resistant material B, C to exert pressure between a user's fingers R and palm S to allow the user to reduce their grip on the tool. The tool Q may be a hammer, screwdriver or other tool. The resistant material may include springs located underneath. The resistant material may be a flexible rubber phase change material such as sodium acetate trihydrate which may increase in temperature from 10 to 30 degrees C once gripped. The aid may be used in a method of using a hand tool such that the phase change material releases heat energy to a user's fingers, palm or hand whilst resistant members exert a comfortable resistant. This aids the use of the tool by user's whose hands may require warmth e.g. those with arthritis, brittle bone joints, cold weather fatigue or hand muscle problems.

Title: Magnetic Hair Accessory Device
Inventor: STAPLETON LISA JILL
IPC: A44C15/00
Filed: 2010-07-20
Abstract: A hair charm or bead comprises a tubular structure divided into two halves 1 that are connected by magnetic means 4, either with one edge hinged 15 or both edges magnetically attached. The charm has a series of hooks 2 of differing lengths provided on an inner surface to prevent movement of the bead in relation to the user's hair. The charms may vary in size by both diameter and length, thus accommodating all hair types and capturing varying amounts of hair. Larger charms may form an elliptical cross section to increase grip on the hair. A charm may also be adapted to provide a means of temporarily attaching hair extensions and decorations which may be attached to the charms themselves. Varying materials dictate the external shape of the charms enabling a range of appearance, value, weight and ornamentation.

Title: Graphical password for controlling access
Inventor: TAYLOR BRIAN HARRY
IPC: G06F21/36
Filed: 2010-08-18
Abstract: A security system for controlling access to local and remote systems, where access is subject to verification of a graphical password or passcode. The passcode comprises a number of elements, and at least one element is selected or input by choosing an area (pixel) of a graphical image, icon, or symbol. The passcode might be chosen by selecting a sequence of pixels (parts/portions/segments/regions) of the image, which will generate a number of passcode digits. Reselecting an identical pixel each time may prove challenging, and thus there may be an acceptable region around the pixel allowing the user a small margin of error. The initially generated passcode may be encrypted and stored in the data storage of the system. This system may be more secure than an alphanumeric password, and the sequence of portions of an image may be easier to remember than a combination of username and password.

Abstract: An X-ray scanning system has an X-ray source having two target areas of two different materials for example one target area 602 of tungsten and one 604 of uranium, arranged to produce X-rays at two different energy spectra. A pair of electrodes 612, 614 may be provided on opposite sides of the path of electron beam 616 which can be controlled to switch an electric field on and off to control the path of the electron beam so that it strikes either one or the other of the target areas 602, 604. The energy spectrum of the X-rays produced at the anode will vary depending on which of the target areas is struck by the electron beam. The target areas may be formed as parallel strips extending along the anode.

Title: Machine-type communication over a radio network is controlled in dependence on the transmission cost determined by the radio network
Inventor: BEALE MARTIN WARWICK
IPC: G01D4/00
Filed: 2010-10-13
Abstract: A method for controlling data transmission from a machine-type communication (MTC), or machine-to-machine (M2M), entity over a radio network in a wireless telecommunications system (fig.3). The method comprises receiving from the radio network a transmission cost parameter representing a cost associated with transmitting data over the radio network T3 and controlling data transmission from the MTC entity in dependence on the transmission cost parameter T4. Thus, the MTC entity is able to select times and/or manner of data transmissions to reduce the overall cost of using the network. Furthermore, the radio network is able to dynamically manage traffic load by providing a cost incentive for transmitting MTC data when network resources are under utilised and applying a cost penalty for transmissions made while the network is relatively busy.

Inventor: QIMING LI
IPC: E21B47/12
Filed: 2010-08-06
Abstract: A dual telemetry system comprises two telemetry systems 51,52, such as mud pulse and wired drill pipe telemetry, which transmit data to and from tools 10 located in a wellbore and terminals 61,62 at the surface to provide back up or redundancy if one system is interrupted.

Title: Grass yield and grazing allocation apparatus
Inventor: HALTON PATRICK
IPC: A01B76/00
Filed: 2012-07-23
Abstract: This invention proposes a method of taking multiple grass-yield measurements and combining the measurement data with geo-location data and a time/date stamp to produce real-time paddock yield data and associated mapping. It provides a means to review the measurements in real-time on an LCD screen. The invention also proposes the facility to enter livestock herd size and type on the display panel in order to determine the setting out of fence-lines regulating the consumption of herbage by the given herd over a time period. Grass height is measured and the apparatus for doing this is wheeled by an operator over the area or paddock to be measured. Grass height is measured by the angular displacement of the float arm 4 supporting float 5 resting on or moving over the grass or herbage. The inclination of the float arm is sensed by means of an accelerometer with an angular measurement which is sent to a data logging and processing unit (16, figure 3).
