| 20090028078 | Method and apparatus for providing security in a radio frequency identification system - A part can receive a communication that originates externally of the part, that conforms to a predetermined communications protocol, and that contains payload information consistent with the protocol but subject to a security provision supplemental to the protocol. The part extracts the payload information from the security provision. | 01-29-2009 |
| 20090028329 | Method and Apparatus for Providing Security in a Radio Frequency Identification System - A response to an event involves transmitting a communication for propagation away from a part externally thereof, the communication containing first and second segments that are respectively subject to first and second security provisions that are different. | 01-29-2009 |
| 20090028333 | Method and Apparatus for Providing Security in a Radio Frequency Identification System - One aspect involves receiving by a tag of wireless communications that utilize a first security provision, and wireless communications that utilize a second security provision different from the first security provision. A different aspect involves receiving by an entity of an authentication request that is based on a first digital certificate unknown to the entity, and determining by the entity, without external authentication of the first digital certificate, whether the first digital certificate is in a trust relationship with a second digital certificate that is different from the first digital certificate and that is known to the entity. | 01-29-2009 |
| 20090028334 | Method and Apparatus for Providing Security in a Radio Frequency Identification System - One aspect involves a communication that contains a portion encrypted with a selected key can be wirelessly transmitted by a part for reception and decryption by plural tags. A different aspect involves a tag receiving a first sequence of wireless communications that each contain sequencing information regarding the first sequence, while receiving a second sequence of wireless communications that each include sequencing information regarding the second sequence, and further involves monitoring the sequencing information from received communications of the first sequence while separately monitoring the sequencing information from received communications of the second sequence. | 01-29-2009 |
| 20090028337 | Method and Apparatus for Providing Security in a Radio Frequency Identification System - A method and apparatus involve storing in a tag a selected digital certificate that permits secure access to said tag from externally thereof. | 01-29-2009 |
| 20090102657 | Method and Apparatus for Tracking and Monitoring Containers - A tag can communicate according to a cellular telephone network communication protocol, and includes one of: passive circuitry, semi-passive circuitry, or circuitry capable of communicating according to a radio frequency identification communication protocol or a satellite communication protocol. According to a different aspect, a tag can receive satellite signals containing positioning information, and can transmit according to one of a cellular telephone network communication protocol, a satellite communication protocol, and a wireless computer network communication protocol. According to yet another aspect, a tag can transmit according to each of first and second communication protocols that are each one of a radio frequency identification communication protocol, a cellular telephone network communication protocol, a satellite communication protocol, and a wireless computer network communication protocol. | 04-23-2009 |
| 20090102658 | Method and Apparatus for Tracking and Monitoring Containers - A tag detects a condition, and selectively operates a portion of its circuitry in first and second modes as a function of information regarding the selected condition, the portion consuming less power in the second mode than the first mode, and being capable of wireless communication according to one of a cellular telephone network communication protocol, a satellite communication protocol, and a wireless computer network communication protocol. According to a different aspect, a tag carries out geofencing analysis, and selectively operates a portion of its circuitry in first and second modes as a function of results of the geofencing analysis, the portion consuming less power in the second mode than in the first mode, and being capable of wireless communication according to one of a cellular telephone network communication protocol, a satellite communication protocol, and a wireless computer network communication protocol. | 04-23-2009 |
| 20090102659 | Method and Apparatus for Tracking and Monitoring Containers - A tag has a sensor that can detect a condition in the region of the tag. The tag effects an operational adjustment relating to the sensor based on sensor configuration information in a received wireless signal. According to a different aspect, a tag can receive wireless signals containing positioning information, and wireless signals containing location information indicating with a first accuracy the current location of the tag. The further signals conform to one of a radio frequency identification communication protocol, a cellular telephone network communication protocol, a satellite communication protocol, and a wireless computer network communication protocol. The tag determines from the positioning information with a second accuracy greater than the first accuracy the current location of the tag, the tag being responsive to the location information for more rapidly effecting the determination with the second accuracy. | 04-23-2009 |
| 20090102660 | Method and Apparatus for Tracking and Monitoring Containers - 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. | 04-23-2009 |
