A method for operating a Wearable Access Sensor ('WAS'). The methods comprise: capturing RF energy by the WAS, where the RF energy is emitted within a surrounding environment from equipment disposed at an access point of a restricted area; passing the RF energy through a switch that is normally in a position which provides an electrical connection between an antenna of the WAS and a full wave rectifier of the WAS; performing operations by the WAS to convert the RF energy into direct current for generating electric power; supplying the electric power to an energy storage device of the WAS for charging the energy storage device to a pre-determined voltage level; and supplying power from the energy storage device to a controller of the WAS when a voltage level of the energy storage device is equal to or greater than the pre-determined voltage level.

Access control system using a wearable access sensory implementing an energy harvesting technique

Systems () and methods () for powering an electrical load () in an environment. The methods involve using a battery () to simultaneously supply electrical energy to control electronics () and a Super Capacitor ('SC') storage element () immediately after a system has been disposed in the environment and turned on. In effect, the control electronics are caused to perform intended functions thereof nearly instantaneously after turning on the system. The SC storage element is charged from a first charge state in which approximately zero volts exist across terminals thereof to a second charge state in which greater than zero volts exists across the terminals. The SC storage element is then used to supply electrical energy to the electrical load of the system so as to cause the electrical load to perform intended functions thereof.

Self sustaining energy harvesting system

Systems and methods for detecting an opening and closing of an object, such as a door or window. The methods comprise: causing a piezoelectric transducer to oscillate in response to an opening of the object; harvesting energy generated as a result of the piezoelectric transducer's oscillation to power a transceiver; and transmitting, from the transceiver to a remote device, information indicating that the opening of the object has been detected by a wireless sensor coupled to the object. The information may specify a logical address linked to a physical location of the object (e.g., a MAC address).

Self-powered door and window opening sensor

Systems () and methods () for controlling access to a restricted area. The methods involve: determining whether a person desires to enter or exit the restricted area based on (1) Received Signal Strength Indicator ('RSSI') measurement data specifying a power present in a signal received from a Wearable Access Sensor ('WAS') worn by the person or (2) rate of change data specifying a rate of change of a charging voltage of an energy storage device disposed within the WAS; and causing actuation of a mechanical actuator to enable the person's entrance into or exit from the restricted area when a determination is made that the person desires to enter or exit the restricted area.

Access control system

Systems and methods for controlling access to a Restricted Area ('RA'). The methods involve: determining whether a person desires to enter RA; checking whether the person is authorized to enter RA using a first unique identifier associated with a wearable access sensor being worn thereby; causing the person's Portable Communication Device ('PCD') to transmit a second unique identifier and location information useful in determining the PCD's location within a surrounding environment, when a determination is made that the person is authorized to enter RA; using the second unique identifier and location information to confirm that the person is currently located at an access point of RA; and causing actuation of a mechanical actuator to enable the person's entrance into RA when it is determined that the person desires to enter RA, the person is authorized to enter RA, and the person is currently located at the access point of RA.

Dual level human identification and location system

A method and system for producing an electromagnetic field that exhibits a strong near field that is sufficient to deactivate an electronic article surveillance, EAS, tag and a weak far field that is insufficient to deactivate the EAS tag are disclosed.

A mixing inlay () is provided which includes a first radiating element (), a second radiating element (), and a non-linear mixing component () connected between adjacent end portions () of the first and second radiating elements. The mixing inlay is configured to receive a first exciter signal having a first frequency and a second exciter signal having a second frequency, and in response, to radiate a mixing product signal produced by the mixing inlay from the first and second exciter signals. A conductive parasitic element () is disposed within a near field of the re-radiating transponder. A distance provided between the conductive parasitic element and the radiating elements is varied over the length of the conductive parasitic element to enhance a sideband signal generated by the mixing inlay.

In one exemplary embodiment, a dipole antenna and a loop antenna are disposed upon a substrate and have dimensions and orientation to exhibit the multiple resonance. The dipole antenna may exhibit a first dipole section having a first length and second dipole section having a second length. The loop antenna may be disposed in a region of the dipole antenna. The ratio of the perimeter of the loop antenna to the sum of the lengths of the dipole sections may be selected to exhibit the multiple resonance.
