20090295545 | Method and System for Variable Operation of RFID-Based Readers Utilizing a Trigger Setting - Described are a communication device and a method for variable operation of RFID-based readers. The communication device includes at least one radio frequency (“RF”) source transmitting an RF signal to at least one target within an operating field and receiving a data signal from the at least one target, at least one trigger activating the at least one RF source, the at least one trigger including a plurality of trigger configurations, each trigger configuration relating to the one or more operating settings, and an RF controller controlling one or more operating settings on the communication device, the RF microcontroller adjusting the setting based on at least one of the plurality of trigger configurations. | 12-03-2009 |
20130113608 | METHOD AND APPARATUS FOR OPTIMIZING MANAGEMENT AND CONFIGURATION OF RADIO FREQUENCY IDENTIFICATION READERS - A host server may optimize configurations of a set of readers under its control. The server assigns a multicast address to each reader in the set. Once connected, the server sends a multicast message to each reader assigned to the multicast address or to each reader within a given address range. Information in the multicast message is used for configuring or managing polling operations of each reader assigned to the multicast address or each reader within the given address range. | 05-09-2013 |
20130154801 | METHOD AND APPARATUS FOR READING RADIO FREQUENCY IDENTIFICATION TAGS WITH LOWEST POWER CONSUMPTION - A method and apparatus for selectively reading radio frequency identification device (RFID) tags by an RFID reader includes the RFID reader transmitting an interrogation signal at each of a plurality of power levels beginning with a lowest power level and sequentially increasing power of the transmitted interrogation signal to a highest power level. The RFID reader receives, in response to transmitting the interrogation for at least one of the power levels, at least one data signal from each RFID tag within a read zone of the RFID reader, wherein each of the data signals contains stored data corresponding to the RFID tag responding to the transmission of the interrogation signal. The RFID reader selectively reads the stored data contained in the data signals received from the responding RFID tags. | 06-20-2013 |
20130154802 | METHOD AND APPARATUS FOR UPDATING A CENTRAL PLAN FOR AN AREA BASED ON A LOCATION OF A PLURALITY OF RADIO FREQUENCY IDENTIFICATION READERS - A method and apparatus updates a central plan for an area based on the location of a plurality of radio frequency identification (RFID) readers by identifying the location of each of the RFID readers using an associated location mechanism. A read zone coverage area for each of the RFID readers is identified. The central plan is updated with the position and the read zone coverage area relative to the position for each of the RFID readers. A status of read zone coverage is determined for the area based on the read zone coverage areas on the central plan for all of the RFID readers in the plurality of RFID readers, wherein a report is provided based on the status of read zone coverage for the area. | 06-20-2013 |
20130169414 | METHOD AND APPARATUS FOR RADIO FREQUENCY IDENTIFICATION (RFID) DATA TRANSMISSION - A method and apparatus for obtaining data of a Radio Frequency Identification (RFID) tag in a virtual read zone of a non-RFID enabled device. The method comprises determining a location of the non-RFID enabled device, determining a virtual read zone of the non-RFID enabled device using at least the location of the non-RFID enabled device, identifying at least one fixed reader device having an RFID read zone that at least partially includes the virtual read zone, reading data of the RFID tag using the at least one fixed reader device, and transmitting the data of the RFID tag from the at least one fixed reader device to the non-RFID enabled device. | 07-04-2013 |

20140161358 | ORIENTATION COMPENSATION USING A MOBILE DEVICE CAMERA AND A REFERENCE MARKER - A method and system for orientation compensation of a mobile device within an environment includes providing a plurality of reference markers having straight edges and having a defined, regular orientation with respect to the environment. Information about the orientation of the reference markers is supplied to a mobile device operating within the environment. An orientation sensor disposed within the mobile device estimates an orientation of the mobile device. An image of one reference marker is captured, and at least one edge of that reference marker is located. The estimated orientation is compensated by correcting for the reference marker orientation and aligning the corrected estimated orientation to the at least one edge of the reference marker that is closest to being parallel to the corrected estimated orientation. | 06-12-2014 |
