Patent GB-2478602-A (GB)
Title: A Semiconductor structure with a quantum dot emitting photons into a waveguide
Inventor: ELLIS DAVID JULIAN PETER
IPC: G02B6/136
Filed: 2010-03-12
Abstract: A semiconductor structure with a layers, one of which 711 is partially laterally oxidized to produce waveguide 721. The laterally oxidised material modifies the lateral effective refractive index with said structure in order to form the waveguide. A quantum dot 717 is configured to emit photons into the waveguide, which is configured such that it guides the output from a single quantum dot. This can be done by etching a pattern on the layer to produce a mesa whose central line is aligned with the quantum dot. The structure can be used for a beam splitter, a random number generator, an interferometer, a phase shifting element, a photonic transistor or a filter.

Abstract: A process for producing an artificial ocular epithelium is disclosed comprising culturing corneal stem cells (e.g. limbal corneal epithelial stem cells) or compositions comprising such cells on a plastically-compacted collagen gel substrate under conditions which provide a population of corneal epithelial cells which produce an artificial ocular epithelium on the substrate. Artificial ocular tissue comprising artificial ocular epithelium and plastically-compacted collagen gel substrate obtained by said process is also claimed. The plastically-compacted collagen gel may be produced from collagen gel by applying a compressing force, dehydration, and/or stretching the gel. The artificial ocular epithelium produced by this method may be used for in vitro ocular toxicity testing, corneal transplantation or methods of treating ocular injury. An artificial ocular epithelium comprising a continuous stratified epithelium of 3-7 cell layers, which expresses cytokeratin-3(CK3) and cytokeratin-14 (CK14), and which has basal membrane components within and between the basal cells, is also claimed.

Title: Authorising payment cards on a vehicle
Inventor: BERNARD CIARAN
IPC: G06Q20/02
Filed: 2010-07-30
Abstract: A system and method for improving the security and efficiency associated with payment transactions is described. The invention more particularly relates to in-flight authorisation of payment cards used in transactions on that flight. By reducing the amount of data that needs to be relayed to the ground as part of the authorisation process, the system enables a real-time authorisation of the payment card. This is achieved by generating a first message 1 from card details used in a transaction at a POS in a vehicle. This message is typically compressed for efficient transmission. The message is received at a remote processing server 220 where it is typically decompressed, and has additional information added to the message from information stored at the server 220 in order to generate an authorization request. The authorization request 3 is then sent to a clearing house 230 and an authorization code 4 is received back at the server 220. A second message 6, including the authorization code is then sent back to the vehicle. The second message can also be processed to reduce its size for transmission. The vehicle may be an aircraft.

IPC: B66F9/065
Filed: 2010-09-14
Abstract: The controller 12 in a load handling machine 1 comprising a machine body 2 and a load handling apparatus 6, 7 that is moveable with respect to the body 2 receives a signal representative of the position of the load handling apparatus 6,7 relative to the body 2, such as the rotation angle of an arm 6 about a fixed pivot, and a signal representative of a moment of tilt of the machine and issues a signal for use by an element (16 fig 2) of the machine 1, such as a movement actuator 8, 10 or a warning indicator (17 fig. 3), to control an operation of the machine 1 when the tilting moment reaches a threshold value, the threshold value being dependent on the position of the load handling apparatus 6, 7 with respect to the machine body 2. When the tilting moment reaches a threshold value movement of the load handling apparatus 6, 7 may be restricted or prevented. The warning indicator (17 fig. 3) may be visual or audible. The tilting moment threshold value may also be dependent upon the deployment of stabilizers S. The signal representative of tilting moment may be provided by a load cell measuring the load on an axle 5. The tilting moment threshold value may vary with the position of the load handling apparatus 6, 7 linearly (fig 4), linearly between two constant values (fig 5) or between two constant values with a step change (fig 6).
Patent GB-2471631-A (GB)
Title: Differential mobility spectrometer and operating method therefor
Inventor: BOULBITCH ALEXEI
IPC: G01N27/64
Filed: 2009-04-17
Abstract: A method of operating a differential mobility spectrometer includes an ionization chamber, a filter channel and a detection region. In the ionization chamber, analyte ions are produced from a sample, the so-obtained ions are then subjected in the filter channel to a time-varying electric field. The time-varying electric field has a longitudinal field component drawing the analyte ions from the ionization chamber through the filter channel into the detection region and a transversal field component, which is the superposition of an asymmetrically oscillating transversal field causing the analyte ions to move to and fro in transversal direction and a compensation field for selecting a species of analyte ions by substantially canceling the average transversal velocity of the selected species. Analyte ions of the selected species having passed through the filter channel are collected in the detection region and a detection signal responsive to the number of analyte ions collected is generated as a functionof the compensating field. The longitudinal field component oscillates in longitudinal direction in such a way that it imparts to the analyte ions on average a non-zero longitudinal velocity in direction of the detection region while it causes them, on a shorter time scale, to move to and fro in longitudinal detection in the filter channel.

Title: Collective operation protocol selection in a parallel computer
Inventor: SMITH BRIAN
IPC: G06F11/34
Filed: 2012-05-24
Abstract: Selecting a protocol to execute with a collective operation running on a parallel computer is carried out by calling a collective operation with operating parameters 602, selecting a protocol 604, and executing the operation with the selected protocol 620. Selection of the protocol involves an iterative assessment of each protocol until one meets predetermined performance criteria, comprising: providing the parameters to a protocol performance function for the prospective protocol 606; determining whether the protocol meets the criteria by evaluating a predefined performance fit equation 610, calculating a measure of the performance of the protocol for the parameters 612; and, if the calculated performance measure is greater than a predefined minimum threshold 614, determining that the protocol meets the criteria and selecting it 618, otherwise proceeding to the next protocol. The selection ensures that a protocol optimized for the particular operation is used, providing greater efficiency in execution.
