摘要:
An apparatus, a system, and a method for communication between multiple base stations and radio frequency (RF) transponders (RF Tags) is disclosed. A first radio frequency (RF) base station for communicating RF signals with an RF tag communicates external trigger signals with at least a second RF base station, which causes the second RF base station to begin transmission.
摘要:
A system, method of use, and a plurality of types of Radio Frequency Transponders (RF Tags). The RF Tags carry a directory or a tag type number which determines the layout of information in the tag memory. The tag type numbers are arranged hierarchically.

A Write Broadcast system and method uses a base station to write sent data associated with no particular destination tag or tags, by radio frequency signal, to all or some selected number (sub group) of tags in a base station field simultaneously. By unselecting the tags that have been successfully written to, and requesting a response from the remaining tags in the field (or sub group), the system determines, by receiving a response to the request, that there are tags in the field (sub group) that were unsuccessfully written to. Another Write Broadcast signal is sent to these tags. The system is useful for quickly (simultaneously) "stamping" information on the tag memory of a large number of tags in the field of the base station.
摘要:
A computer implemented method for logging extensions to platform configuration registers inside a trusted platform module instance is provided. A request to extend the current state of at least one of a plurality of platform configuration register is received. At least one platform configuration register within the trusted platform module instance is extended. The extension of the at least one platform configuration register is logged inside the trusted platform module instance as a logged entry by storing at least a tuple of platform configuration register indexes and hash values used for extending the platform configuration register. Information about new entries in the consolidated logs can be retrieved by polling or by subscribing to events that are automatically generated. A report of an extend operation and its logged hash value is sent to subscribers interested in receiving notifications of extend operations on a set of PCR registers.
摘要:
A trusted platform module is presented that is capable of creating, dynamically, multiple virtual trusted platform modules in a hierarchical organization. A trusted platform module domain is created. The trusted platform module creates virtual trusted platform modules, as needed, in the trusted platform module domain. The virtual trusted platform modules can inherit the permissions of a parent trusted platform module to have the ability to create virtual trusted platform modules themselves. Each virtual trusted platform module is associated with a specific partition. Each partition is associated with an individual operating system. The hierarchy of created operating systems and their privilege of spawning new operating systems is reflected in the hierarchy of trusted platform modules and the privileges each of the trusted platform modules has.

摘要:
A method, article of manufacture and computer product is presented for a vehicle customization, restriction, and data logging capability. The invention leverages the increasing electronic content in vehicles by interconnecting these electronic devices with a controller. It further uses a storage device in the vehicle, to store vehicle customizations and/or restrictions, and to provide capability for defining and logging significant vehicle events. Combining the electronic vehicle components with a storage device (sometimes in the form of a smart card or floppy disk, etc.) and a controller in a vehicle network enables providing operator specific settings for each of a set of vehicle operators. These customizations add to operator and passenger comfort and safety. It also enables application of setting restrictions to and logging the vehicles use parameters. These add previously unavailable tools to entities as diverse as a parent monitoring a teen driver, a company or government agency regulating a truck driver, an operator training facility, a vessel captain or pilot, a rental car company setting terms for a car rental and handling returns off line, and a car owner relinquishing the vehicle to a parking lot attendant.
摘要:
A method of sending data from a base station to a passive RF tag and writing the data to a tag non-volatile memory which detects a “partial write”, where the tag voltage falls during the write process under the voltage sufficient to reliably write the tag non-volatile memory, is presented. The tag voltage is compared to a stable reference voltage during the time the tag memory is being written, and if the tag voltage falls below an acceptable level, a flag in the tag non-volatile memory is cleared.
