摘要： Systems (100) and methods for determining a location of a tag (310). The methods involve: receiving, at each detector of a plurality of detectors (202-216, 306, 308), a device transmission periodically transmitted from the tag; determining, by the detectors, Received Signal Strength Indictors (“RSSIs”) for the device transmission received thereat; determining, by a computing device (218), a probable location of the tag within the passage, first demarcated area or second demarcated area using the RSSIs and relationships between the RSSIs; determining a first likelihood value indicating the likelihood that the probable location is correct; and determining an estimated location of the tag within the passage, first demarcated area or second demarcated area based on the probable location when the first likelihood value meets a first criteria.

摘要： Interference in an electronic article surveillance (EAS) system is reduced by transmitting warning pulse at a predetermined time following the EAS marker exciter pulse. The predetermined time and duration of the warning pulse are chosen so that the warning pulse acts upon a noise interference avoidance process in a second non-cooperative EAS unit. More particularly, the warning electromagnetic pulse causes a timing change in a second synchronized electromagnetic exciter pulse produced by the second EAS unit when the second synchronized electromagnetic exciter pulse is concurrent with the first receive interval. This timing change causes the second EAS unit to no longer interfere with the first EAS unit.

摘要： A system and method for monitoring the status of wireless node devices in a network. A network controller polls one or more sensor devices for status information. The sensor devices are in communication with at least one wireless node device. More than one sensor device may be associated with a single wireless node device. The wireless node device appends its own status information to the transmission frame of the sensor device's response message, and the transmission frame, containing the address and status information for both the sensor device and the wireless node device, is transmitted to the network controller. The inclusion of the wireless node device address and status information is done without the knowledge of the sensor device.
