摘要:
An ionization system for a predefined area includes a plurality of emitter modules spaced around the area, a system controller for individually addressing and monitoring the emitter modules and communication lines for electrically connecting the plurality of emitter modules with the system controller. Each emitter module has an individual address and including at least one electrical ionizer.

Circuitry is provided in a device to automatically change the relative position of the electrical lines which enter the device upon detection of a miswired condition. More specifically, the circuitry allows the device to function normally even if an installer accidentally inverts (i.e., flips or reverses) the wiring connections when attaching connectors to a communication/power line of the device. In this manner, the installer does not need to rewire the lines.

A room ionization system includes a plurality of emitter modules, each including an electrical ionizer. The emitter modules are spaced around the room and are connected in a daisy-chain manner to a system controller. Each emitter module has an individual address for allowing the system controller or a remote control transmitter to individually address and control each emitter module. Electrical lines containing both power and communication lines connect the plurality of emitter modules with the system controller. Each emitter module stores a balance reference value and an ion output current reference value for use by automatic balance control and automatic ion output current control circuitry. These reference values are stored in a software-adjustable memory so that they may be easily changed via the system controller or via the remote control transmitter if actual measured balance or decay times in the work space, such as measured by a charged plate monitor, indicate an ion imbalance or out of range ion output current. Each emitter module can send detailed alarm condition information and emitter module identification information to the system controller upon detection of a malfunction. Each emitter module connected to the system controller may be individually set to a desired operating power mode. The emitter modules use a switching power supply to lessen effects of line loss. Each emitter module includes miswire protection circuitry so that the electrical lines may be automatically flipped if initially connected in the reverse manner.

摘要:
A tracking system uses RFID (radio frequency identification) tag technology to facilitate the identification and tracking of items in an environment through a technique known as shadowing. As an object or target moves within a pre-described detection zone with communicating antenna and RFID sensors, the object or target blocks the line of sight between respective antenna and sensors, preventing electromagnetic coupling between the sensor and the antenna and thus casting an electromagnetic shadow along the line of sight. One approach of this invention uses this shadow technique to perform functions such as theft (shrink) deterrence/detection; tracking the motion of objects through an environment by monitoring the shadow; and correlation analysis of people shadows to tagged items (e.g., merchandise, articles) to foster marketing and merchandizing effectiveness.

A method of balancing positive and negative ion output in an electrical ionizer having positive and negative ion emitters and positive and negative high voltage power supplies associated with the respective positive and negative ion emitters includes automatically adjusting at least one of the positive and negative high voltage power supplies by ramping up or ramping down the at least one of the positive and negative power supplies at a predetermined rate. Another method of balancing positive and negative ion output in an electrical ionizer having positive and negative ion emitters and positive and negative high voltage power supplies associated with the respective positive and negative ion emitters includes automatically adjusting at least one of the positive and negative high voltage power supplies by ramping up the at least one of the positive and negative power supplies at a predetermined rate upon initiation of the operation of the electrical ionizer.
