Publication number: 20060121905Abstract: A wireless communication system (500) provides a number of communication resources for a plurality of mobile stations (512-516). The wireless communication system employs a call gapping process and comprises a number of communication paths for routing a communication initiated by one of the plurality of mobile stations (512-516) to a destination node. One or more of the plurality of mobile stations (512-516) is configured to perform the call gapping process. A communication unit and a method of congestion relief are also provided. The proposed technique provides congestion relief using call gapping, extended to use by a wireless subscriber unit to minimise air-interface traffic in a wireless communication environment. In this manner, calls are prevented from being initiated when they would have ultimately resulted in an unconnected call.Type: ApplicationFiled: February 24, 2004Publication date: June 8, 2006Inventors: Paul McDonald, Martin Ellis

Patent number: 6491702Abstract: A method and apparatus for defining the location of a medical instrument relative to features of a medical workspace including a patient's body region are described. Pairs of two-dimensional images are obtained, preferably by means of two video cameras making images of the workspace along different sightlines which intersect. A fiducial structure is positioned in the workspace for defining a three dimensional coordinate framework, and a calibration image pair is made. The calibration image pair comprises two 2D projections from different locations of the fiducial structure. After the calibration image pair is made, the fiducial structure is removed. A standard projection algorithm is used to reconstruct the 3D framework of the fiducial structure from the calibration image pair. Appropriate image pairs can then be used to locate and track any other feature such as a medical instrument, in the workspace, so long as the cameras remain fixed in their positions relative to the workspace.Type: GrantFiled: May 29, 2001Date of Patent: December 10, 2002Assignee: Sofamor Danek Holdings, Inc.Inventors: Mark Peter Heilbrun, Paul McDonald, J.

Patent number: 6324274Abstract: A user profile for use, for example in a personal numbering service, has an associated confidence value for each of the destination terminal numbers in the profile, a confidence value representing the confidence of a call being successfully answered at the associated network terminal. When a service using the profile needs to route a call for a user, the corresponding profile is accessed and the call is routed to the destination terminal number having the highest confidence value. The profile is managed to modify the confidence values depending upon the outcome of the call, and also upon registration of a personal number user at a network terminal. The confidence values are probabilities and when one confidence value is increased because of a successful outcome, the other values are adjusted. The confidence values can be a function of time to represent lessening confidence that a user is still at the network terminal of his last registration.Type: GrantFiled: April 1, 1998Date of Patent: November 27, 2001Assignee: British Telecommunications public limited CompanyInventors: Richard J Akester, Paul McDonald

Patent number: 6188962Abstract: A system for seismic data acquisition has been invented having, in certain aspects, one or multiple distributed data acquisition subsystems that are independent of energy source controller and/or of navigation system operation. Thus the distributed acquisition system(s) do not require a complicated and burdensome interface to the energy source controller or navigation systems. The seismic data acquisition system supplies a continuous flow of data which is buffered within a centralized data repository for short term storage until required by non-real-time processes. A seismic data acquisition method has been invented that replaces conventional closely coupled interaction between seismic acquisition systems and the energy source controller and the navigation systems by utilizing GPS time stamps on both the data as well as cycling events of the energy source controller and/or navigation systems to insure precise association of seismic data with cycling events.Type: GrantFiled: June 25, 1998Date of Patent: February 13, 2001Assignee: Western Atlas International, Inc.Inventors: Paul McDonald Morgan, William Alfred Guyton, Kenneth Graeme Williamson

Patent number: 5995063Abstract: The present invention relates to radio communications and in particular to antenna structures. There is a growing demand in the radio communication system market to reduce the size and cost of radio communication sites and to reduce the maintenance costs involved. Many radio communication sites are also costly and difficult to maintain especially when dealing with components of the antenna structures which are located near the top of the antenna structures. The present invention attempts to address these problems. The present invention provides an antenna structure comprising a hollow antenna mast having an inside and an outside, a movable module disposed inside the hollow antenna mast and a lifting mechanism. The movable module has at least one antenna and/or at least one RF module. The a lifting mechanism permits the raising and lowering of the movable module inside the hollow antenna mast. Furthermore, the communications equipment can be placed inside the hollow antenna mast.Type: GrantFiled: August 13, 1998Date of Patent: November 30, 1999Assignee: Nortel Networks CorporationInventors: Vincent Somoza, Paul McDonald

Patent number: 5969497Abstract: An electric induction motor can be given a kick start without excessive current drain on the supply by first connecting a unidirectional supply to a winding of the motor to build up a stationary rotor flux and then applying a starting current to another winding of the motor to produce a stator flux at an appropriate angle (between 0.degree. and 180.degree.) with the stationary rotor flux. Once the motor has begun accelerating the normal running supply can be connected. This starting current may be derived from a capacitance which is charged up during the period of establishing the stationary rotor flux.Type: GrantFiled: November 25, 1998Date of Patent: October 19, 1999Assignee: EA Technology LimitedInventors: Stephen Paul McDonald, Geoffrey David Baines, John Talbot Boys
