摘要： A beacon device includes a control circuitry, a window, and a plurality of sets of illumination sources. The window includes a prismatic structure forming a ring from a planar perspective. The prismatic structure defines an inside surface and an outside surface from the planar perspective. The plurality of sets of illumination sources are coupled to the control circuitry. Each set of illumination sources includes a first illumination source disposed proximal to the inside surface of the prismatic structure and includes a second illumination source disposed proximal to the outside surface of the prismatic structure. The control circuitry is to illuminate a first set of the plurality of sets of illumination sources to transmit a signal in a first direction.

摘要： A system includes a beacon device including a communication strip having a plurality of directed light emitters distributed along the communication strip. The beacon device can transmit a directed light signal via the directed light emitters. The system further includes a tag including a processor, a radio frequency transmitter coupled to the processor, a directed light receiver coupled to the processor, and a lens having first and second major surfaces and a side surface, the tag to receive the directed light signal via the side surface and to transmit a radio frequency tag message via the radio frequency transmitter. The system also includes a radio frequency reader to receive the radio frequency tag message.

摘要： A plurality of tags communicates a plurality of messages to a reader device. A message collector at the reader device collects at least a subset of the received messages, and provides the collected messages to a set of logical readers. The message collector and the logical readers filter the collected messages based on configuration information provided by an associated application, and provide tag event information to the application based on the filtered messages. The reader device can be configured based on customized configuration information, so that the tag event information provided to an application is customized for that application.
