Publication number: 20090322492Abstract: A system is disclosed for tracking and controlling shopping carts or other types of human-propelled vehicles. In one embodiment, the system includes a wheel or wheel assembly with a braking mechanism that is activated in response to signals received by multiple receivers. The receivers may, for example, include a VLF (Very Low Frequency) receiver for detecting a VLF signal transmitted by a buried cable, and an RF transceiver for communicating over a wireless network. The receivers may, but need not, be included in the wheel. The multiple receivers may be used in combination to control a shopping cart; for example, a command received by a shopping cart's RF transceiver may cause the cart to ignore (not activate the brake in response to) a detected VLF signal.Type: ApplicationFiled: September 1, 2009Publication date: December 31, 2009Inventors: Stephen E. Hannah, Scott J. Carter, Jesse M. James

Patent number: 6958677Abstract: An object location monitoring system includes beacons that are spatially distributed throughout an area to be monitored. The beacons transmit interrogation signals that are received and echoed by transponders that attach to moveable objects. Each beacon retransmits its interrogation signal, and any transponder response thereto, to a receiver that measures a time difference between the two signals. This time difference reflects the signal propagation time, and thus the distance, between the beacon and the transponder. One such receiver preferably analyzes the retransmitted signals of multiple (e.g., 50 to 100) beacons. A triangulation method is used to determine the location of each transponder based on the transponder's distances from a set of beacons. In one embodiment, the transponders are provided as or within disposable ID bracelets worn by patients, and are used to track the locations of the patients within a hospital.Type: GrantFiled: April 2, 2001Date of Patent: October 25, 2005Assignee: GE Medical Systems Information Technologies, Inc.Inventor: Scott J.

Patent number: 6907283Abstract: Various designs and features of an ambulatory transceiver and ECG lead set are disclosed for use in remote patient monitoring. One feature involves the use of unshielded, dual-conductor lead wires in which one conductor carries the patient's ECG signal and the other conductor provides an RF antenna element for the transceiver. The lead wires used in one embodiment provide improved flexibility, durability, and antenna performance over conventional lead sets with shielded wires. Another feature involves an antenna diversity scheme in which the transceiver switches between two or more ECG-lead antennas, each of which is formed from one or more ECG leads of the lead set. Another feature involves the use of a circuit within the transceiver to monitor, and dynamically compensate for changes in, the impedance of an ECG-lead antenna or a conductor thereof. Another feature is an improved circuit for protecting the transceiver from damage caused by defibrillation pulses.Type: GrantFiled: May 11, 2001Date of Patent: June 14, 2005Assignee: GE Medical Systems Information Technologies, Inc.Inventors: Scott J.
