Patent number: 8279116Abstract: A method of processing received satellite radio signals is disclosed in which signals are received the signals from plural satellites through a common antenna. The received signals are digitised to produce a time-series of digitised signal samples and a plurality of replicas representing the signals of each of the plurality of satellites are obtained. At least one sample is selected from each of the replicas and the elements of a register are set equal to the selected replica samples. Thereafter, in turn, for each one of said digitised signal samples, the value of the digitised signal sample is combined with each of the values of the elements of the register to produce corresponding modified values; and the modified values corresponding to each of said register elements are accumulated.Type: GrantFiled: January 7, 2009Date of Patent: October 2, 2012Assignee: Cambridge Positioning Systems LimitedInventors: Peter James Duffett-Smith, Robert Willem Rowe, Anthony Richard Pratt

Patent number: 8103294Abstract: In a terminal 106 having a receiver 202 for receiving the signals from plural transmission sources 101-105 whose positions and transmission time offsets are unknown within the terminal, a method is provided for determining the change in the time (elapsed time) at the terminal between two instants. At a first position of the terminal a first set of measurements, aligned to a first instant, of a signal parameter representative of the time or phase of receipt of said signals from said plural transmission sources relative to one or more of them, or to a reference, or to a terminal clock is obtained. Then at a second position of the terminal a corresponding second set of measurements, aligned to a second instant, of a signal parameter representative of the time or phase of receipt of said signals from said plural transmission sources relative to one or more of them, or to the reference, or to the terminal clock is also obtained.Type: GrantFiled: March 12, 2008Date of Patent: January 24, 2012Assignee: Cambridge Positioning Systems LimitedInventors: Peter James Duffett-Smith, Robert Willem Rowe, Murray Robert Jarvis, Simon David Hern, Nicolas Guy Albert Graube

Publication number: 20110043406Abstract: A method and apparatus are disclosed for determining the position, or change in the position, of a mobile terminal. The terminal has a receiver for receiving the signals from one or more transmission sources at unknown positions and an independent positioning device able to find, when operative, the position of the mobile terminal. The method uses the independent positioning device to measure the position of the mobile terminal at one or more first locations. A respective first set of time or phase offset values of signals received from the transmission sources relative to each other or to a reference in the mobile terminal is measured in the mobile terminal, at each first location.Type: ApplicationFiled: January 15, 2009Publication date: February 24, 2011Inventors: Peter James Duffett-Smith, Robert Willem Rowe, Murray Robert Jarvis

Publication number: 20090111482Abstract: A method and apparatus are described for determining whether a mobile terminal 105 of a communications system has moved outside a locale 107. The terminal is able to measure the relative time offsets of the signals, received by the terminal from transmitters of the network, relative to each other or to a reference. The method includes measuring, at a first time when the terminal is within a given locale, the time of receipt of the signals received by the terminal from a plurality of the transmitters 101-103 relative to a reference or to each other, to create a first set of one or more receive time offsets and storing the first set. At a second time when it is desired to determine whether the mobile terminal has moved outside said locale, the time of receipt of one or more signals received by the terminal 105 from one or more transmitters 101-103 of the plurality of transmitters relative to a reference or to each other is measured, to create a second set of one or more receive time offsets.Type: ApplicationFiled: June 12, 2006Publication date: April 30, 2009Applicant: CAMBRIDGE POSITIONING SYSTEMS LIMITEDInventors: Robert Willem Rowe, Peter James Duffett-Smith

Patent number: 7508883Abstract: The present invention sets out to overcome the hearability problem in CDMA communications networks in which positioning services are provided, by using a separate sampling device 204, 205, 206 for each transmitter 201, 202, 203, which sends to the computing device 208 a representation of the signals transmitted only by that transmitter. A cross-correlation of the representation sent back by the mobile terminal 207 with the representation sent back by the sampling device in the brightest transmitter is performed in the computing device 208, and a blurred estimate of that brightest signal is subtracted from a blurred version of the representation sent back by the mobile terminal 207 in order to reduce its effect on the remaining signals as far as possible. The cross-correlation and subtraction steps are iterated until no useful signals remain to be extracted.Type: GrantFiled: May 13, 2003Date of Patent: March 24, 2009Assignee: Cambridge Positioning Systems LimitedInventors: Peter James Duffett-Smith, Malcolm David Macnaughtan, John Christopher Clarke, Robert Willem Rowe

Patent number: 7315745Abstract: The invention provides a method of estimating the time offsets between signals transmitted by plural transmitters of a communications network and received by a receiver attached to a terminal. In the method a section of a representation of the signals from the plural transmitters received by the receiver at the terminal (a “terminal section”) is created as are a first section of a representation of the signal transmitted by a first of said transmitters and a second section of a representation of the signal transmitted by a second of said transmitters. Each of the first and second sections overlaps in time with the terminal section. Using the first section, the second section and a set of signal parameters, including initial estimates of the time offsets between the first section and the terminal section and between the second section and the terminal section, a model of a section of a representation of the composite signal received by the receiver from the first and second transmitters is created.Type: GrantFiled: August 18, 2003Date of Patent: January 1, 2008Assignee: Cambridge Positioning Systems Ltd.Inventors: Peter James Duffett-Smith, Malcolm David MacNaughtan, Christopher John Clarke, Robert Willem Rowe

Patent number: 6491882Abstract: The invention relates to a high-pressure device (1) having a cylindrical high-pressure vessel (3) and prestressing means in order to exert an axial pressure on the vessel. The vessel (3) can have been formed from a number of layers of composite material, such as glass, carbon or aramide fibers which are oriented in the peripheral direction and are embedded in a matrix of epoxy resin or polyurethane. By applying the axial prestress to the pressure vessel (3), the tangential stress is distributed more uniformly over the wall thickness of the high-pressure vessel (3), the stress decreasing at the inside of the wall and increasing at the outside thereof. As a result, the innermost fibers of a high-pressure vessel (3) made of composite material are subjected to appreciably less stress, which has a beneficial effect on the life of the high-pressure vessel (3), and all fibers of the wall are utilized effectively.Type: GrantFiled: November 27, 2000Date of Patent: December 10, 2002Assignee: ATO B.V.Inventors: Robert Willem Van Den Berg, Paul Vincent Bartels, Ludo Jean Maria Mathilde Van Schepdael
