The present invention generally relates to systems, methods and applications utilizing the convergence of any combination of the following three technologies: wireless positioning or localization technology, wireless communications technology and sensor technology. In particular, certain embodiments of the present invention relate to a remote device that includes a sensor for determining or measuring a desired parameter, a receiver for receiving position data from the Global Positioning System (GPS) satellite system, a processor for determining whether or not alert conditions are present and a wireless transceiver for transmitting the measured parameter data and the position data to a central station, such as an application service provider (ASP). The ASP, in turn, may communicate the measured data, position data and notification of any alerts to an end user via an alert device. The present invention also relates to various applications and systems utilizing the capabilities of such a device.

Systems and methods for monitoring and tracking

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.

Embedded bio-sensor system

Provided is a bio-sensor system which utilizes radio frequency identification technology and which includes a remote transponder in wireless communication with an implantable on-chip transponder. A power supply collects alternating current voltage pulses from an electro-active polymer generator embedded in muscle tissue for generating power for the on-chip transponder. The power supply is specifically adapted to provide a stable and precise sensor reference voltage to a sensor assembly to enhance the accuracy of measurements of a physiological parameter of a patient. The remote transponder receives data representative of the physiological parameter such as glucose concentration levels. The data is processed and transmitted to the remote transponder by the on-chip transponder. The precision and stability of the sensor reference voltage is enhanced by the specific circuit architecture of a glucose sensor to allow for relatively accurate measurement of glucose concentration levels without the use of a microprocessor.

A moving electrical contact for connecting a track-mounted moveable carriage to a signal rail. The moving electrical contact comprises a spring plate secured to the moveable carriage on one end and a contact pad attached to the other end of the spring plate. The contact pad is biased against the signal rail by the tension in the spring plate. The contact pad is constructed from approximately sixteen layers of a wire mesh consisting of tin coated, stainless steel conductive wire knitted in a tricot pattern and may include conducting jelly.

A method for confirming the authenticity of an article including placing a semi hard piece of material on an article then printing a magnetic pattern on the semi hard piece of material. In order to view the pattern, a viewer containing a suspension of materials will be placed over the semi hard piece of material. The suspension of materials will then orient in the presence of a magnetic field adjacent to the magnetic material.

A desensitizer apparatus for desensitizing a security sensor element in a book spine. The apparatus includes a scanner which scans along a surface against which book spines are positioned and which detects sensor elements in the spines to be sure that only one book is positioned against the surface. If only one sensor element is detected, a signal is generated which operates a drive mechanism to move desensitizer magnets close to the surface to deactivate the sensor element in the book.

Magnetically desensitized targets or sensor elements on protected articles are resensitized by means of rotating permanent magnets which are moved relative to the magnetized target desensitizer elements such that the elements become subjected to reversing magnetic fields of gradually decreasing intensity.

Method and apparatus for sensitizing and desensitizing targets for

Articles of merchandise (42) which contain deactivatable theft detection targets (44) have their targets deactivated by passing them through a box-like apparatus (30) made of low coercive force, high saturation induction material with a multiplicity of permament magnets (48) on its inside surfaces so as to generate magnetic fields which extend at different directions and at decreasing intensities from one end of the apparatus to the other so that irrespective of a target's orientation while passing through the apparatus, the target's magnetic deactivation slugs or elements will encounter a magnetizing field along the target's length sufficient to magnetize the elements.
