A device for deactivating a magnetomechanical EAS marker includes two coils and an energizing circuit for alternately driving the coils. One coil is driven for one cycle of an alternating power signal, and then the other coil is driven for one cycle, and this sequence is repeated. The driving signal is switched from one coil to the other at a point in time which corresponds to a zero crossing of the current level of the driving signal.
Antenna Arrangement With Reduced Coupling Between Transmit Antenna And Receive Antenna
An antenna arrangement in which a first antenna means is arranged to define a null contour adjacent the first antenna means and at which the magnetic flux from the first antenna means is substantially a null and in which a second antenna means is arranged to substantially follow the null contour.

Abstract:
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.

Abstract:
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.

Abstract:
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.
Tooele, UtahAssistant General Manager at Tooele Hampton Inn Almost married a year. Hopefully I will be able to move back to Arizona and finish college soon.
The death was the second climbing death in the park this year. On May 18, Richard Copeland, 50, an experienced climber who lived in Kings Canyon National Park, died from a fall while approaching a well-known climb on Liberty Gap in Yosemite.
