Patent number: 7634428Abstract: Apparatus and methods for an electronic shopping service. The service enables a consumer to select line items from electronic receipts and group them as a review list. The consumer may create groups of people to have access to the review list and may assign access permissions to each of the review groups. A member of a review group may review the items in a review list and comment on the items. The comments may be directed to the consumer or to other members of the review group. The review may be off-line or on-line, as in a chat session or telephone or audiovisual conference. The consumer or a review-group member may order on-line any of the items listed in a review list. The consumer or a review-group member may add products from e-commerce sites to the review list (if so authorized). The shopping service handles the ordering. Where the items to be purchased are from multiple e-commercial sites, the shopping service places multiple orders as necessary, with shipping and payment as directed by the consumer.Type: GrantFiled: September 15, 2000Date of Patent: December 15, 2009Assignee: Symbol Technologies, Inc.Inventor: Anandakumar Varatharajah

Patent number: 7633974Abstract: A system and method is provided for reordering the transmission of data packets in a queue of a radio system when an error occurs during the transmission of a data packet to any device destination address. A transmission ordering component is provided that transmits data packets in a queue one at a time until a transmission error occurs for a given destination address. The transmission ordering component then searches through the queue for a data packet with a different destination address than the current destination address being transmitted. The transmission ordering component then returns to transmitting packets one at a time until the end of the queue is reached. Once the end of the queue is reached the transmission ordering component reorders the queue and moves the packets in which transmission errors have occurred to the beginning of the queue. The transmission ordering component then repeats the transmitting data packets one at a time.Type: GrantFiled: August 20, 2007Date of Patent: December 15, 2009Assignee: Symbol Technologies, Inc.Inventor: Mark Russell DeFord

Publication number: 20090303047Abstract: Methods, systems, and apparatuses for tracking and monitoring tagged objects in an RFID environment is described. By varying RFID reader antenna output power levels and detecting RFID devices in the vicinity, data about position and orientation of the RFID devices can be gathered. This gathered data is used to correlate with pre-stored data about RFID devices' position and orientation. Such a correlation then can be used to infer data about neighboring RFID devices based upon data stored in the database. Such an inferential technique also results in a faster analysis of position and orientation data of RFID devices, and also leads to faster tracking of RFID enabled devices. Unnecessary reads and high power operations of the RFID reader are also avoided.Type: ApplicationFiled: June 10, 2008Publication date: December 10, 2009Applicant: Symbol Technologies, Inc.Inventor: Charles Rinkes

Patent number: 7630323Abstract: Methods and apparatus are provided for forming a wireless personal area network (WPAN) from an array of intercommunicating personal area network (PAN) devices. The system comprises a location determinator configured to determine a location for each of the PAN devices, a comparator coupled to the determinator for comparing the location of each of the PAN devices with WPAN association criteria to choose a subset meeting the WPAN criteria at least in part, and a communication link coupled to the comparator to transmit identification data of the subset to some or all of the subset of PAN devices. When received, the information causes the subset to form the WPAN, which then intercommunicate substantially ignoring the non-WPAN devices. In a preferred embodiment, the comparator selects the WPAN from those of the plurality of PAN devices that are within a predetermined distance of each other and/or move as a group.Type: GrantFiled: March 11, 2004Date of Patent: December 8, 2009Assignee: Symbol Technologies, Inc.Inventor: Raj Bridgelall

Patent number: 7619524Abstract: A system and method to distinguish an RFID tag which is moving synchronously with an RFID reader from other RFID tags which are not moving synchronously with the reader. In one embodiment, the reader emits read signals at a fixed frequency with a corresponding period. A determination is made by the RFID reader as to the signal strengths received from an RFID tag at time intervals which are integer multiples of the half-period of the signal. Signal strengths from the tag which are the same or substantially the same at these prescribed measurement intervals are taken as an indication that the tag is moving synchronously with the RFID reader. In an alternative embodiment, the frequency of the read signals may vary over time. Correlations between received tag signal strengths with particular frequencies are an indication that the RFID tag is moving synchronously with the RFID reader.Type: GrantFiled: July 20, 2007Date of Patent: November 17, 2009Assignee: Symbol Technologies, Inc.Inventor: Russell Calvarese
