Title: Time interval measurement between events occuring at two separate locations
Inventor: STRIBLEY KEITH ROLAND
IPC: G01S5/14
Filed: 2000-02-16
Abstract: A dual frequency (L1, L2) Global Positioning System (GPS) receiver at each location is capable of both Coarse Acquisition (C/ A) Code and carrier phase measurements. An accurate frequency reference source giving local time, a data-logger for logging the GPS data and a Time Interval Counter (TIC) are used to measure the local time of a local event A communication system passes the logged GPS data and time interval data from each location to the central processor system (CPS.) The CPS derives a time-offset figure, which is calculated using a predetermined algorithm which is indicative of the difference between measured times, and dependent upon the frequency reference sources at the two locations. The CPS can then determine the time interval between events. The system may be used to determine the arrival time of a signal from an aircraft, the resulting time intervals at a number of locations can be used to determine the aircraft height. The frequency reference may be a quartz crystal or a rubidium oscillator.

IPC: H04L27/20
Filed: 2000-04-10
Abstract: In a phase fluctuation generation circuit and a phase fluctuation generation method, an eight-bit parallel count output from a shift register(653, Fig 3) in a control section 65 is input to a multiplexer 5 as a phase modulated signal, whereby normally the multiplexer 5 functions as a 1/8 division counter. Eight-bit parallel data with the value of "1" shifted by counting up is input from the shift register 653 to the multiplexer 5. The division ratio becomes 1/9 only once. The multiplexer 5 outputs a signal to a phase detector 2 as a phase fluctuation signal with a phase lead of only one clock. May be used for measuring the transmission quality of high speed digital communication system. The output of the phase detector 2 controls a voltage controlled oscillator (VCO) 4.

Title: Communications system with network address translation
Inventor: READ STEPHEN MICHAEL
IPC: H04L12/46
Filed: 2000-11-30
Abstract: The present invention relates to a communications system 1 for handling communications sessions, for example multimedia calls or voice calls. The communications system comprises a local terminal 10, an external server 40, a proxy interface agent 11 between the terminal 10 and a shared network 20. The communication means includes a NAT function 32 through which the communications session must pass. The communications session is carried over the network over one or more logical channels between the terminal 10 and the external server 40, during which the first NAT function 32 applies network address mappings on the terminal's transport addresses 14. The proxy interface agent 11 acts on behalf of the terminal in communications with the external server and establishes a logical channel on an outbound connection to the server that serves as a control channel between the proxy interface agent and the server. The proxy interface agent establishes dynamic outbound connections to the server, and in response to a request from the server, makes one or more associations between the terminal's transport address(es) and identifiable logical channel(s) between the proxy interface agent and the server. These identifiable logical channel(s) are established on one or more of the dynamic outbound connections from the proxy interface agent to the server.

Title: Peizoelectric device for detecting or measuring the bending of objects
Inventor: DUERDEN ROGER
IPC: G01L1/16
Filed: 2001-05-03
Abstract: The device is made of multiple layers of flexible material, including at least one piezoelectric layer 3 and at least one conductive layer 1. The layers can be very thin, producing a device suitable for use where space is limited. The device produces a large output signal and the conductive material may be arranged to provide screening from electromagnetic interference. The device is bonded to the object to be measured using adhesive 4, sealing the piezoelectric and conductive materials from the environment and preventing the ingress of substances that may damage them or impair their operation. The object has conductive areas arranged so that, in bonding the device and object together, the electrical connections to the device are made. Therefore layers 2 and 4 are conductive adhesive layers. When appropriately mounted on a suitable object of known mechanical characteristics, the device can be used to measure strain, shock and acceleration to which the object is subjected or bending of the object.

Title: A quantum dot photon source
Inventor: SHIELDS ANDREW JAMES
IPC: H01S5/34
Filed: 1999-11-23
Abstract: A photon source 21 can emit single photons, or pulses of N photons, at predetermined intervals. The source comprises at least one quantum dot 35 having two energy levels which can be respectively populated by an electron and a hole, there being supply means which can supply a predetermined number of caters to one of the energy levels to allow recombination of a predetermined number of carriers in the quantum dot so that at least one photon is emitted. The quantum dot(s) are encapsulated between two layers having a different lattice constant to the quantum dot(s) and may formed in a cavity between two mirrors 51,53, e.g. Bragg mirrors, one of which may be partially reflective to allow the photon(s) to enter an optical fibre. The supply means may be a laser beam, pulsed or continuous, to excite carriers into the energy levels, and may have means to modulate the transition energy of the quantum dot(s), e.g. by applying an AC voltage thereacross. In the case of pulsed laser excitation, the pulses desirably have a duration less than the relaxation time of the carriers which are excited, and the time between the leading edges of successive pulses is greater than the recombination time of an electron and a hole in the quantum dot. The source may be used in optical quantum cryptography, or for optical imaging, spectroscopy, laser ranging and metrology.
