Title: Receiver for quantum cryptography system which selectively inverts an element of the received signal
Inventor: YUAN ZHILIANG
IPC: H04L9/08
Filed: 2005-09-09
Abstract: The quantum communication receiver preferably includes an interferometer. One arm of the interferometer is supplied with an "operator" device 515. If the system encodes bits using phase, then the operator is a phase modulator. If the system encodes bits using polarisation, then the operator is a polarisation rotator. The operator is controlled by two control devices. The first control device is a basis selection controller 521 which imposes a basis to be used to measure the received signal, as in prior art systems. The second control device 523 is an inversion controller. The inversion controller selectively instructs the operator to apply either an invert operation or a null operation. The invert operation inverts the signal passing through the operator arm, after the basis has been selected, for example by applying a 180 degree phase shift or a 90 degree polarisation rotation as appropriate. The output of the interferometer is passed to at least one detector 503, 505 for distinguishing the state of received signal. The detector output(s) is/are passed to a detection processor which inverts the detector output(s) only if the invert operation was applied in the interferometer.

Filed: 2006-03-15
Abstract: An apparatus comprises a conditioning element, such as a concentrator (filter) 104/102 and pump 110, and purge system for conducting a purge cycle. During the cleaning purge cycle, gas flows into the conditioning and/or filter element in a reverse direction, flowing in opposite direction to that during normal flow operation; a control system autonomously initiates the cleaning reverse purge. Also claimed is an apparatus comprising an inlet filter 102, concentrator 104, and coupled downstream control valve 218 and pump 220; again, pump 220 operates to cause reverse air flow during the clearing purge, under automatic sensor control. The control valve 218 may have first and second states, respectively connecting the pump to the conditioning element or the conditioning element/filter to a sampling or analysis device or detector 114. Automatic purging may be effected based on elapsed time, or sensed flow or pressure changes, i.e. as the filter clogs or blocks.

Title: Mass spectrometer with asynchronously functioning beam attenuator and mass analysis apparatus.
Inventor: GREEN MARTIN
IPC: H01J49/42
Filed: 2005-04-04
Abstract: A mass spectrometer is disclosed comprising an ion beam attenuator which attenuates an ion beam repeatedly switching between a zero transmission mode of operation during a time period   W  T1 and a non-zero transmission mode of operation during a time period   W  T2. The degree of attenuation of the ion beam can be varied by varying the mark space ratio   W  T2/  W  T1. The ion beam attenuator may release ions in packets or pulses but the packets or pulses of ions may be converted into a continuous ion beam by a relatively high pressure ion guide or gas collision cell arranged downstream of the ion beam attenuator.

Title: Apparatus for and a method of determining surface characteristics
Inventor: MANSFIELD DANIEL IAN
IPC: G01B11/06
Filed: 2006-07-19
Abstract: Light (4) is directed along a sample path (SP) towards a sample surface (7) and along a reference path (RP) towards a reference surface (6) such that light reflected by the surfaces interfere. A mover (11) effects relative movement along a scan path between the sample surface (7) and the reference surface (6). A detector (10) provides a series of intensity values representing interference fringes produced by a sample surface. A processor (32) receives first intensity data resulting from a measurement operation on a surface area of a substrate and second intensity data resulting from a measurement operation on a surface area of a thin film structure. The processor (32) determines a gain (100) for the film structure(s) and determines a substrate surface characteristic (101) on the basis of the first intensity data, determines an apparent thin film structure surface characteristic on the basis of the second intensity data, and modifies the apparent thin film structure surface characteristic using the substrate surface characteristic and the gain(s) determined by the gain determiner.

Title: Game device
Inventor: OKAMOTO KOJI
IPC: A63F13/212
Filed: 2005-06-13
Abstract: A game device with which a game is played such that a moving body such as a ball displayed on a screen is caused to hit one or more targets displayed on the screen. The moving body in movement displayed on the screen of a TV set is caused to hit the targets by changing the movement of the moving body based on an input from an input device operated by a game player. Operation timing determination means (49) determines timing of operation of the input device operated by the player. Means (51) for changing the moving direction of the moving body changes, upon receiving a change command while moving the moving body, the direction of movement of the moving body according to the change command. The operation timing determination means outputs the change command to the means for changing the moving direction of the moving body based on the determined operation timing.

Title: Managing nodes in a distributed system by registering and making available nodal information to nodes.
Inventor: THOMAS MARK RALPH
IPC: G06F15/173
Filed: 2007-05-18
Abstract: A network management apparatus (1) arranged for use in managing a network of computers each defining a node of the network. The apparatus includes a registry (7) arranged to receive nodal information from one or more nodes (4, 5, 6) identifying the means employed by a node for communicating with nodes. The registry makes available to a node received nodal information in response to a request from the node for that nodal information to enable a determination of whether or not the node possesses means for communicating with nodes which is compatible with the means for communicating with nodes possessed by another node. This enables a given device to determine whether or not it is able to communicate directly with another device providing a desired service. The device may decide not to communicate with the other device, or seek to communicate with a different device. The decision may be result from the determination that the given device and the other device do not employ compatible communication means. The nodal information may be the network address, the technology employed by a node, or the functions and/or services provide by a node to other nodes. The system may be employed within a marine vehicle.

Title: Fully variable LED brightness using a digital control method
Inventor: JEWELL KENNETH JOHN
IPC: H05B44/00
Filed: 2007-08-09
Abstract: An LED controller receives a variable Pulse Width Modulated signal, which is then inverted. The inverted signal is level shifted to a current limited voltage level. This signal is then filtered and the output is used to drive a FET, IGBT, Transistor or other current amplifying device to switch the LED load. The LED brightness level is controlled by the width of the pulse being generated by the micro-controller, other IC or other source. This application can also be fabricated into a specifically designed (IC) Integrated Circuit therefore reducing the need for external hardware and no micro-controller would be required. This application can be integrated into any product or application that requires fully variable (LED) Light Emitting Diode brightness using a digital control method. This application will allow any LED's to be fully dimmed from completely off to fully on (0 to 100%) without any noticeable stepping.

Abstract: A puzzle game consists of two or more homogeneous single or multi-facet puzzle pieces, each facet having three or more edges and each edge ascribed with a single indicia. The indicia are allocated such that when all, or a sub-set, of the puzzle pieces are placed in an unique relative two or three-dimensional positional and rotational configuration, so that indicia of two adjacent puzzle piece match in either two or three-dimensions, a required two or three-dimensional configuration/pattern ('target') is obtained.

The indicia can be an alphanumeric character, a solid or broken colour, a pattern consisting of two or more colours, raised dots, one or more shapes/symbols or combinations of these. The puzzle pieces may have attachments allowing them to be joined. The pieces may also have passive or electronic identification to allow the location of the pieces within the completed puzzle to be determined.
