Patent number: 8319646Abstract: A tag has a circuit portion that functions as a reader capable of wireless communication with other tags. According to a different aspect, a tag has a circuit portion with first and second modes, the circuitry consuming less power in the second mode than the first mode, and exiting the second mode only in response to an act by a human. According to yet another aspect, a tag can receive wireless communications conforming to one of a cellular telephone network communication protocol, a satellite communication protocol, and a wireless computer network communication protocol. The tag responds to receipt of a predetermined wireless signal conforming to the one protocol by carrying out one of first action that includes causing the tag to enter an electronically secure state, or a second action that includes causing the tag to exit the electronically secure state.Type: GrantFiled: September 24, 2008Date of Patent: November 27, 2012Assignee: Savi Technology, Inc.Inventors: Allan M.

Patent number: 8264331Abstract: A tag can receive first and second wireless signals respectively defining first and second transmission fields that overlap. When the tag moves from the first field to the second field through the region of overlap, the apparatus transitions only once from recognizing the tag is in the first field to recognizing the tag is in the second field. According to another aspect, first and second signposts are supported at spaced locations in the region of a crane, and respectively transmit first and second wireless signals that are different, and that respectively define first and second fields of transmission. According to yet another aspect, a signpost transmits wireless signals having a transmission field, and a system senses positional information regarding a tag movable relative to the signpost, the system using the positional information to determine a location of the tag in relation to the transmission field.Type: GrantFiled: April 2, 2007Date of Patent: September 11, 2012Assignee: Savi Technology, Inc.Inventors: Albert Nardelli, Stephen E.

Patent number: 8253541Abstract: An apparatus (10, 240, 300) includes a signpost (11, 241-256, 322, 612, 623, 626-628, 652, 661, 682, 686, 703) which transmits signpost signals (24) that are received by a tag (12, 271-275, 301-316, 395-397, 616-618, 641-643, 653, 656-657, 662-664, 679, 708, 711). The tag in turn transmits radio frequency beacon signals (72) which are received by a reader (13, 261, 319, 521-530). The tag can vary the duration of the beacon signals, for example in dependence on whether it is currently receiving a signpost signal. Further, the tag can dynamically vary the transmission rate and/or transmission power of the beacon signals, for example following receipt of a signpost signal. Varying these parameters can facilitate compliance with governmental regulations.Type: GrantFiled: September 2, 2005Date of Patent: August 28, 2012Assignee: Savi Technology, Inc.Inventors: Joseph S.

Patent number: 8111141Abstract: Systems and methods provide for determining a distance between a signpost and a tag and for locating a tag using multiple signposts. The system uses a signal received at a tag from a signpost, and from them measures the signal strength of the signal with respect to one or more antennas on the tag. The system calculates an RSSI using the measured signal strength, from which a distance can be determined between the signpost and the tag. The system also uses signals received from multiple signposts, to measure multiple signal strengths, resulting in multiple distance determinations corresponding to the various signposts, thereby establishing a location for the tag.Type: GrantFiled: March 30, 2007Date of Patent: February 7, 2012Assignee: Savi Technology, Inc.Inventors: Timothy K.

Patent number: 7667597Abstract: A seal device includes a locking member with a magnetically permeable material portion, and structure that can receive the locking member. The structure supports a magnetic field generator and detector at locations spaced from each other and from a region that is occupied by the portion of the locking member when the locking member is received by the structure. The structure defines a main flux path as a loop having a first portion, a second portion and a remainder that are mutually exclusive, and that collectively define the entirety of the flux path. The first and second portions are respectively within the magnetic field generator and the region, and most of the remainder extends through magnetically permeable material of the structure. The detector is located where the magnetic field has different characteristics when the portion of the locking member is respectively present in and absent from the region.Type: GrantFiled: August 31, 2007Date of Patent: February 23, 2010Assignee: Savi Technology, Inc.Inventors: Richard L.

Patent number: 6750771Abstract: A reader reads identifiers from tags on pallets conveyed past the reader. The reader includes two interleaved linear arrays of antennas with circularly polarized fields. Each antenna is composed of a pair of crossed rods phased to have adjacent antennas of an array generate circularly polarized fields of opposite rotation. The vector components of the polarization in the direction across the width of the conveyor have peaks and nulls, and the interleaved arrays are arranged such that the nulls of one array's fields are covered with the peaks of the other array's fields. This arrangement allows the reader to the identifier from the tag when the tag is at any orientation. A tag at the side of the reader is aligned in the direction of travel by rails on the conveyor. The reader has antennas aligned in the direction of travel to read such tags.Type: GrantFiled: July 24, 2001Date of Patent: June 15, 2004Assignee: Savi Technology, Inc.Inventor: Timothy K. Brand
