Patent number: 5473330Abstract: A tagging system (20) compensates for both resonant frequency spatial dependent shifts and resonant frequency dependent shifts for detecting data resonant circuits (DC1-DC6) on an RF tag 10 which is carried by a tagged object (34). The system includes at least one transmitter (26) and at least one receiver (28) for determining the actual resonant frequencies of reference resonant circuits (SC1-SC5, FC1-FC4) on the tag 10. A microprocessor controller (22), in response to the frequency difference between the undisturbed resonant frequencies of the reference resonant circuits and the actual resonant frequencies of the reference resonant circuits, provides compensating factors to compensate for the spatial and frequency effects of the resonant frequencies of the resonant circuits on the tag (10). The transmitter and receiver determine the actual resonant frequency of each data resonant circuit (DC1-DC6) on the tag (10).Type: GrantFiled: November 17, 1993Date of Patent: December 5, 1995Assignee: Motorola, Inc.Inventors: George L.

Patent number: 5381137Abstract: RF tagging system (10) has a plurality of resonant circuits (13) on a tag (12). When the tag (12) enters a detection zone (14), the system determines the resonant frequency of each of the resonant circuits (13) and produces a corresponding code. Preferably, resonant frequency detection is implemented by simultaneously radiating signals at each possible resonant frequencies for the tag circuits (13). The system is useful for coding any articles such as baggage or production inventory. Preferably, the radiated signals are phase shifted during the detection process, and signals received by receiver antennas, besides transmitter signals, may be monitored to improve the reliability of detecting the resonant circuits (13). Also, a preferred step adjustment configuration for capacitive metalizations (106, 110) of the resonant circuits is described.Type: GrantFiled: October 26, 1992Date of Patent: January 10, 1995Assignee: Motorola, Inc.Inventors: Sanjar Ghaem, Rudyard L.

Patent number: 5146231Abstract: An electronic direction finder (10), having a housing (11) with a major axis (18), has a GPS receiver (28) and directional (31) and omnidirectional (30) antennas and provides an electrical signal (angle A) indicative of the direction of the housing axis (18) with respect to a predetermined compass heading (North). The electrical signal (angle A) is provided by using determined positions of the GPS receiver (28) and one GPS satellite to calculate a compass bearing from the receiver (28) to the one satellite and using the directional antenna (31) to determine the orientation of the housing axis (18) with respect to the satellite. This eliminates using electrical output terrestrial magnetism sensing devices to sense direction finder/receiver orientation with respect to compass direction, and therefore avoids the inaccuracies and costs associated with such magnetism sensing devices.Type: GrantFiled: October 4, 1991Date of Patent: September 8, 1992Assignee: Motorola, Inc.Inventors: Sanjar Ghaem, George L.

Patent number: 4811233Abstract: An improved cost-optimal state feedback control system for stabilizing the nertial reference platform in all-attitude inertial guidance systems which uses the "region" control concept. It reduces the computational requirements of cost-minimizing state feedback to within the capacity of aerospace vehicle onboard control processors. The control system iterates the feedback compensation process so as to reduce the R-gyro error to essentially a zero value and to prevent the gimbal assembly from entering a "gimbal lock" orientation.Type: GrantFiled: April 2, 1987Date of Patent: March 7, 1989Assignee: The United States of America as represented by the Secretary of the NavyInventor: George L.
