Title: Correlating the mode or identification of an input prosthetic with a function
Inventor: MICHAELIS PAUL ROLLER
IPC: G06F3/033
Filed: 2011-04-08
Abstract: Input from a prosthetic 30 on e.g. (a touch screen) is detected. The mode of operation or identification information associated with the prosthetic is correlated with the input to a function. For example, an LED, RF transponder, or comparable electrical, optical, and/or electromagnetic components that allows the characteristics of the prosthetic to be changed can be used to correlated to different modes of operation when used with a corresponding input device. Prosthetics with different shapes to affect different modes of behavior may be used with an input device, such as a touchscreen or touchpad. Even further aspects are directed toward providing handicapped individuals with increased dexterity by providing a prosthetic that allows different modes of behavior when used with an associated input device. The distance of the prosthetic device may also be determined.

Title: Transmit antenna selection in a multi-carrier, multi-antenna transceiver using signal metrics associated with signals received by the transceiver
Inventor: LOPEZ RAFAEL ARCANGEL CEPEDA
IPC: H04B7/06
Filed: 2011-05-24
Abstract: The invention applies to a wireless transceiver comprising a plurality of antennas and operable to transmit data on a plurality of subcarriers from one or more of said plurality of antennas over a communication channel. The invention lies in selecting the antennae which are to be used for transmission. The transceiver receives signals via each of the antennas, and determines the number of subcarriers that can be allocated to each of the antennas, for data transmission, on the basis of received signal metrics associated with said received signals (steps S1-0 to s1-6). Preferably, this determination involves, for each antenna, plotting a graph of the number of sub-carriers received as function of the power of received signals and applying linear regression. Transmit antenna selection is performed on the basis of the number of subcarriers which can be allocated to each antenna (steps s1-6 to s1-13). This enables unused RF chains to be switch-off. Transmit antenna selection can be performed without carrying out FFT processing of received signals.

Title: Image formation using pixelated spatial light modulator
Inventor: CHRISTMAS JAMIESON
IPC: G02B27/42
Filed: 2011-08-05
Abstract: There is provided a method of forming an image in which the phase delay difference between pairs of adjacent pixels on a pixellated spatial light modulator is used to selectively redirect light in one axis to form pixels of an image. Each pixel of the SLM may be arranged to apply a single phase delay to light incident on that pixel. The method may find application in Schlieren projection systems wherein the phase difference causes a portion of the output light to be diffracted around an optical or Shlieren stop. A 1D lens may also be used to perform a 1D Fourier transform on the light processed by the spatial light modulator.

Title: Process of gas containment
Inventor: SEVIER DAVID
IPC: B01D53/18
Filed: 2013-04-24
Abstract: A process for containing at least a target gas in a flowing gas mixture within a defined area (5) by use of at least a pair of target gas capture (6,7,8) and release (2,3,4) sections in fluid communication with one another. Each pair of capture and release sections has a high surface area medium and a fluid contained therein and include a fluid entry point at a first end and a collection tank at a second end. The process comprises the steps of: directing a gas mixture through a flow path, to direct the gas mixture through the target gas release section followed by the target gas capture section. The fluid contained within the pair of capture and release sections allows for the target gas/es to be contained within a defined area between the target gas capture and release sections. The fluid is directed through a recirculation path, that directs the fluid from said collection tank of the target gas capture section to the entry point of the target gas release section and from the collection tank of the target gas release section to the entry point of the target gas capture section, thereby recycling the fluid. The pair of capture and release sections include a concentration gradient of at least one of the target gas and the fluid. Advantageously the process may be utilised to control humidity levels in buildings or machines.

Title: Safety Door
Inventor: HALL BENJAMIN
IPC: E06B3/32
Filed: 2013-12-20
Abstract: A bi-directional safety door assembly includes a door frame with a door leaf hingedly mounted in the frame so as to be openable in a first direction. The hinged mounting 20 of the door leaf is located on a doorpost 15 mounted to be pivotable about an axis 25 parallel to and spaced from the hinged door mounting. The doorpost can thus pivot between a first rotational position in which the door leaf is openable in one direction only from its closed arrangement, and a second rotational position in which the leaf edge remote from the hinge is pulled away from the frame, enabling the door to be pulled open in a direction opposite to its normal opening direction. In this way the door can be opened in an emergency even when opening on its normal opening side is prevented by locking or by a heavy object placed against it.
