A method is provided for tracking an object, including positioning a radio frequency (RF) driver to radiate an RF driving field toward the object, and fixing to the object a wireless transponder that includes a power coil and at least one sensor coil. The method also includes receiving the RF driving field using the power coil and storing electrical energy derived therefrom. A plurality of field generators are driven to generate electromagnetic fields at respective frequencies in a vicinity of the object that induce a voltage drop across the at least one sensor coil. A digital output signal is generated at the wireless transponder indicative of the voltage drop across the sensor coil, and the generation of the digital output signal is powered using the stored electrical energy. The digital output signal is transmitted from the wireless transponder using the power coil, and the transmission of the digital output signal is powered using the stored electrical energy. The digital output signal is received and processed to determine coordinates of the object.

Apparatus for remote interaction with an object of interest includes a remote station for obtaining information from the object of interest, a base station for transmitting energy in space to and communicating with the remote station and the remote station having conversion means for energizing the remote station responsive to receipt of the transmitted energy. The energy may be of any suitable type including RF power, light, acoustic, magnetic energy or other form of space transmitted or "radiant" energy. The remote station does not have to contain a source of stored energy or a wired connection to a source of energy. The remote station receives the energy transmission and data transmission from the base station and transmits data to the base station. Microprocessor controllers may be provided for the base station and the remote station. The remote station may receive information from sensors and through one or more transponders sequentially communicate information to the base station. An associated method is provided. In other embodiments which are suited for use in miniaturized electronic chip systems, power enhancement and increased effective antenna size are provided. An electronic article containing a microchip having at least one antenna structured to communicate with an antenna remotely disposed with respect to the microchip formed therein and an associated method are provided.

A measuring device for measuring geometric properties of a medical treatment device includes a measuring unit, a time detection unit, and an RFID writer. The measuring unit is configured to measure a relative position between at least a first part of the medical treatment device and at least a second part of the medical treatment device. The time detection unit configured to detect a time of the measurement, and the RFID writer configured to write a time, based on the detected time, to an RFID transponder of the medical treatment device.

Provided is a bio-sensor system which utilizes radio frequency identification technology and which includes a remote transponder in wireless communication with an implantable passively-powered on-chip transponder. The bio-sensor system is specifically adapted to provide a substantially stable and precise sensor reference voltage to a sensor assembly that is included with the on-chip transponder. The remote transponder is also configured to remotely receive data representative of a physiological parameter of the patient as well as identification data and may enable readout of one or more of the physiological parameters that are measured, processed and transmitted by the on-chip transponder upon request by the remote transponder. The precision and stability of the sensor reference voltage is enhanced by the specific circuit architecture of the glucose sensor to allow for relatively accurate measurement of the physiological parameter such as measurement of glucose concentration by a glucose sensor without the use of a microprocessor.

A wireless system and method for determining the location of a fixed or mobile target configured to have a transponder on the target, a transceiver monitoring the target location, communicating between the transponder and transceiver, and a processor for finding the target by virtual triangulation based on values of received position information. The processor is determines virtual triangulation based on successive values of the position information using at least three points P1, P2 and P3 of the transponder respective of the transceiver. The present invention discloses methods for finding with virtual triangulation by: (1) finding with virtual triangulation by generating position information in real-time, in the case of (i) stationary and moving target, and or (ii) in the case of the presence of obstacles; (2) finding with virtual triangulation relating to the average speed of the motion of operator; and or (3) finding with simplified virtual triangulation.

An apparatus and method for controlling user access to electrical receptacles and telephone and network communications receptacles. The device features a short range radio receiver and one or a plurality of RF energized radio identification tags with transmittable identification transponder codes. The receptacle contains circuitry that detects the immediate presence of energized transponders with proper identification codes and only enables the electric, telephone or network access from the receptacle to become active if the correct matching transponder identification code is present. The tag is a small flexible device having one side that may be attached to the plug or the receptacle or interfaced therebetween. Access to the power or network is allowed for a defined duration of time or only so long as the transponder remains energized and transmits the identification code.

A system for measuring the position of transponders for testing and training a user to manipulate the position of the transponders while being guided by interactive and sensory feedback through a bidirectional communication link to a processing system for the purpose of functional movement assessment for exercise and physical rehabilitation.

The present invention is an RF system and methods for finding a target T in three dimensional space configured to have a transponder disposed on the target T, a monitoring unit configured as a transceiver for determining or monitoring the location of the target T and an RF wireless communication system configured with a processor to repeatedly determine position, communication and other values between the transponder and monitoring unit and so as to generate a measured distance between units in three dimensional space by determining the measured distance of the target T by a spherical virtual triangulation relationship when successive values of said position information has a predetermined logical relationship relative to said previous values between said monitoring unit and transponder and / or slave unit disposed on the target T.
