20080204193 | Method and apparatus for active RFID network - A method and an apparatus for evaluating an expression embedded inside a communication packet received from an RFID (Radio Frequency Identification) interrogator device are described. The evaluation result may determine a selection with another RFID interrogator device. An RFID data packet may be sent to an RFID interrogator device based on a selection to be associated with the RFID interrogator. A task may be performed based on the evaluation as instructed by a remote RFID interrogator through a command included in the wireless communication packet. | 08-28-2008 |
20080284566 | Location based electronic sign system - A method and an apparatus for determining the proximity between an electronic sign and one or more object items to transmit presentation information to the electronic sign are described. The determination may be based on a signal wirelessly generated from the electronic sign. The presentation information displayed at the electronic sign may describe the one or more object items. Locations of the one or more object items may be determined based on wirelessly received identifiers of the one or more objects items, a portable wireless device, and the electronic sign. | 11-20-2008 |
20090153348 | Method and apparatus for electronic-sign system - A method and apparatus that select presentation information for an electronic sign wirelessly placed within a proximity of one or more object items are described herein. The electronic sign displays the presentation information. An alert message is determined in response to a signal received from the electronic sign according to objects items in proximity locations of the electronic sign. The determined alert message is sent to the electronic sign to replace the displayed presentation information. | 06-18-2009 |
20090281888 | Method And Apparatus For Establishing Time-Based Loyalty Relationship - A method and apparatus that determine a time window based on a presentation schedule for a multimedia content in response to receiving the presentation schedule is described herein. The multimedia content is played according to the presentation schedule at a predetermined location. During the time window, an interactive user interface pattern is presented within a vicinity of the predetermined location. In response to receiving a user input via the interactive user interface pattern, a reward is generated during the time window. | 11-12-2009 |
