Abstract: Example embodiments disclosed herein relate to optimizing operation of an electronically steerable antenna (ESA) with respect to temperature-related constraints. Thermal load experienced by individual antenna elements or tiles of the ESA is balanced to maximize an expected time before the ESA reaches a shutdown temperature. An example method includes determining a reduced number of antenna tiles that minimally satisfies a signal quality requirement with respect to a target system. The method further includes selecting an optimized sequence of tile patterns of the reduced number of antenna tiles within the ESA. The optimized sequence corresponds to an optimized path that traverses a graph having nodes corresponding to the tile patterns and edges defining a count of shared tiles between respective tile patterns. The method further includes operating the ESA according to the optimized sequence of tile patterns based on activating specific tiles identified by each pattern in a sequential manner.

Abstract: The loss prevention system is a system to prevent articles from becoming lost, misplaced, or stolen. The articles are tagged with, or contain, an identifying device such as an RFID tag or a wireless network interface. The identifying device allows the articles to be monitored by a monitor. The monitor periodically interrogates each identifying device with a transmitted RF signal, and generates an alarm signal if an interrogated identifying device does not reply or is out of range. The identifying devices can be acquired by the monitor and associated with an alias that can be used to associate the identifying device with its associated article.
