Patent number: 6876107Abstract: A controlled motion system, which has a mover that is movably mounted on a track for moving along a path. Active and reactive elements are associated with the track and mover, and are configured for driving and controlling the mover along the path. A controller is operatively associated with the active elements for controlling the driving of the mover, and a position sensor is associated with the track and configured for sensing the position information corresponding to the position of the mover along the path. The sensor is associated with the controller for transmitting the position information to the controller. The sensors are also preferably configured such that the position information is transmitted from the mover through the sensor at a sensing speed faster than about 10,000 meters per second.Type: GrantFiled: June 5, 2003Date of Patent: April 5, 2005Assignee: Jacobs AutomationInventor: Keith Jacobs

Publication number: 20040189516Abstract: A method for navigation processing in a satellite positioning system receiver is disclosed. A method in accordance with the present invention comprises separating the three SATPS satellites into a first pair and a second pair, constructing a primary solution and an alternate solution, wherein the primary solution and the alternate solution satisfy the measurement constraints, computing a Doppler difference estimate for the primary solution and a Doppler difference estimate for the alternate solution, computing Doppler difference residuals for the first pair and the second pair of SATPS satellites, and comparing the Doppler difference residuals for said primary and alternate solutions to determine a valid solution. Typically, the computing of a Doppler difference residuals comprises differencing a measured Doppler difference from an estimated Doppler difference for the first pair and the second pair of SATPS satellites.Type: ApplicationFiled: October 21, 2003Publication date: September 30, 2004Inventors: Keith Jacob Brodie, David Allan Tuck, Mangesh M.

Patent number: 6597988Abstract: The invention comprises a set of pseudolites deployed throughout an area of interest in which the GPS constellation visibility may be limited, such as in and around some high-rise buildings in an urban setting, and a database of these installed pseudolite locations with their PRN numbers indexed by cell-site. When the cellular telephone is in communication with a particular tower or transceiver, the PRN numbers of all local psuedolites are transmitted to the cellular telephone. If the cellular telephone has a position solution which has been transmitted to the cell tower, prepositioning information for a code search can be transmitted to the phone as well. The phone can then augment the phone's normal acquisition list with the psuedolites in the area and track the pseudolites to augment navigation capabilities in a harsh environment.Type: GrantFiled: September 21, 2001Date of Patent: July 22, 2003Assignee: SiRF Technology, Inc.Inventors: Keith Jacob Brodie, David Allan Tuck

Patent number: 4574247Abstract: An FM demodulator wherein the input signal excursions advance a counter. At each of a sequence of equal sample times, the count is compared to a value which is the average of the highest and lowest counts during the sequence. The comparison may be numerically direct or by down-counting from a present number. The result of the comparison sets an output data value either "1" or "0".Type: GrantFiled: May 21, 1984Date of Patent: March 4, 1986Assignee: Multi-Elmac CompanyInventor: Keith Jacob

Patent number: 4161659Abstract: A magnetic proximity sensing apparatus for sensing ferro-magnetic objects is especially well adapted for use with fluid cylinders having pistons formed from magnetically attracted material. The apparatus includes a magnetic actuator responsive to the proximity of the fluid cylinder piston or other ferro-magnetic object which closes a switch and enables electrical circuitry for controlling fluid valves or other apparatus. A reed switch mounted within a hollow, cylindrical, permanent magnet has a separate pole piece secured at one end of the reed switch. The proximity of a ferro-magnetic object changes the flux within the magnet, closing the reed switch. The circuitry is solid state and includes a silicon controlled rectifier acting as a gated switch for completing the circuit.Type: GrantFiled: June 9, 1978Date of Patent: July 17, 1979Assignee: Scovill Manufacturing CompanyInventor: Keith Jacob
