Abstract: A system for controlling door-mounted or door-embedded antennas. An antenna, for example, an EAS or an RF antenna, sends interrogation signals which are received by markers located on merchandise within a range of detection, i.e., an “interrogation zone”. Antennas that are mounted on or embedded in a door move along with the motion of the door. Thus, the interrogation zone covered by the antenna's magnetic field is continually changing with the movement of the door. The system and method of the present invention control door-mounted antennas by monitoring the motion of the door upon which the antenna is mounted, and by adjusting the size and breadth of the interrogation zone generated by the antenna accordingly.

Abstract: A door and method of constructing a door whereby antenna coils are routed through channels that are incorporated within the frame of the door, and completely or partially hidden from sight. The door includes channels and or troughs that are sized to retain at least a portion of the antenna therein. The door can be purchased with the antenna wires already embedded therein and hidden from sight and installed at a facility without the need to mount the antenna wires on a pedestal or dig up floors and/or walls to embed the antenna coils. Existing doors can be retrofitted to install the antenna wires. Such antennas may be used, for example, in an RFID marker system or a magneto-acoustic EAS marker system.

Abstract: A method of characterizing an electron beam is described, comprising providing a system including an electron gun having a steering coil. A material having a surface is also provided. An electron beam from said electron gun is directed to said surface. The directing includes providing a first current to the steering coil to direct the electron beam to a first point on the surface and then providing a second current to the steering coil to direct the electron beam to a second point on the surface. An imaging system is mounted for viewing said surface. An image is collected based on light emitted from the surface because of the electron beam directed at the first point and the second point. A light intensity is determined at the first point and at the second point.

Abstract: Techniques to generate data models for an item master having a number of items. Each item is associated with a number of attributes and each attribute is associated with a set of values. In one method, the items in the item master are initially classified into a number of pagesets, with each pageset being defined by a unique combination of values for a first set of (classification) attributes. For each pageset, a second set of (selectable) attributes is determined to uniquely identify the items in the pageset. The selectable attributes may be selected from a list of candidate attributes, which may include mandatory attributes designated to be used as selectable attributes and optional attributes that may be selected for use. Data models are generated for each pageset based in part on the selectable attributes, and include a set of tables descriptive of the items in the pageset.
