Title: Quantum dot photon source with reduced output pulse duration
Inventor: BENNETT ANTHONY JOHN
IPC: H01L31/00
Filed: 2004-12-03
Abstract: A photon source comprises at least one quantum dot, a carrier injection means and a change of state means. Carriers are injected into the photon source and recombine radiatively within the quantum dot causing a pulse of photon emission. The state of the carriers in the quantum dot is changed after a predetermined length of time which is less than the radiative decay time. This allows the optical output pulse duration   W  to be selected, thus reducing the jitter in the device. Preferably a pulsed electrical bias is applied to the photon source to change the state of the carriers which includes removal or addition of one or both types of carrier from or to the quantum dot, emptying the quantum dot of all types of carrier, separating the carriers within the source body of moving the carriers into an optically dark state. The carriers may be injected into the quantum dot by electrical or optical excitation.

Title: Intrusion detection with false alarm prevention
Inventor: ALLEN LES
IPC: B60R25/10
Filed: 2005-01-10
Abstract: A method 300 for determining an intrusion into a confined space comprises detecting motion 305 using a secondary sensor and generating an alarm signal 310 at the secondary sensor in response to the detected intrusion. The method further comprises determining 315 whether the alarm signal represents a false alarm and inhibiting 325 a primary sensor in response to a false alarm condition. The determination of a false alarm may include frequency filtering, comparison of the signal with a threshold level 315 and detection of stochastic characteristics 320 indicating a false alarm. An alarm is sounded 340 only in response to an alarm signal being received from both the secondary and primary sensors. The primary sensor may be inhibited 325 for a predetermined time interval on determination of a false alarm signal. As an alternative to disabling the primary sensor, the system may inhibit another part of the alarm system to prevent alarm generation. The primary sensor may be an ultrasound detector; the secondary detector may be a microphone, accelerometer, vibration detector or strain detector.

Title: Craft having flow-producing rotor and gyroscopic stability
Inventor: HATTON GEOFFREY
IPC: B64C17/00
Filed: 2005-05-03
Abstract: In a craft having a rotor 9A, 9B, 9C producing a flow over an aerodynamic (eg. domed) surface 1, to create lift or thrust, the gyroscopic effect of the rotor, when driven at full power, is such as to give the craft positive stability.

Patent GB-2445595-A (GB)
Title: Location system
Inventor: BARTLETT DAVID
IPC: G01S5/02
Filed: 2007-01-08
Abstract: A tag repeatedly transmits signals having two or more different frequency components. The signals are received by one or more (e.g. three or four) spaced receivers. Each receiver, in response to receiving a signal, measures the relative phases of the first and second frequency components and a frequency offset between the tag and the receiver. The frequency offset is dependent upon a difference in frequencies of respective clocks in the tag and the receiver. A position processor obtains a difference in phases of the first and second frequency components for a signal, a frequency offsets between the receiver and tag and determines the position of the tag in dependence upon multiple differences between respective phases of the first and second frequency components determined at different times and in dependence upon the frequency offsets. Alternatively the tag may receive and the spaced receivers are replaced by transmitters. The system may also evaluate speed using Doppler, and use this to improve the accuracy of the measurements. Multipath errors can be overcome. Preferably the receivers and transmitters are synchronized, but they can be asynchronous.

IPC: G06F11/14
Filed: 2005-09-30
Abstract: Disclosed is a method for storing recovery data at a remote destination or location. The data is sent in chucks, each of which represents data covering a known time period, with a subsequent chuck covering the immediately following time period. Synchronous data, corresponding to the data chunks, is also sent to a local minimal storage location such that the local store contains data that is not stored on the remote store and the remote store contains data that is not stored locally. An indicator that a new chuck of data is being sent is provided to the storage locations. The data stored in the remote store may be older than the data stored locally. The data stored at the local store may be stored as a linked list of elements, which are sorted according to the location of the data source or according to the order of receipt. A local cycle number may be provided at the local store and be incremented when the new data chuck indicator is received.

The system 100 includes means interacting with the database 400 to present to a user file identifiers indicative of virtual data files (e.g. video clips) apparently available from the system though not assembled into files, and responds to a request from the user for access to data in a virtual file indicated by a selected file identifier by assembling from the database 400 and the high capacity store 300 a file containing the selected data. The server may be configured to offer virtual files in a plurality of forms, including at least one of: different file formats, different essence compressions, different essence sizes and different sample rates. In a preferred embodiment, the system detects when an ordered sequence of files is being requested by the user and predicts the opening of the next file in the sequence, thereby enabling the next file to be prepared for user access prior to the receipt by the system of a request therefor from the user.
