摘要:
A method and system for facilitating radio frequency (RF) communication between a radio frequency identification (RFID) device and RFID tags is disclosed. The method may include associating one or more RFID tags to one or more containers that comprise a container volume, wherein the RF signal communication between the RFID device and one or more of the RFID tags is at least partially obstructed, and integrating at least one conductive surface into the container volume, wherein if the RFID device is coupled to at least one of the conductive surfaces and energized, the RFID device, the at least one conductive surface and one or more of the RFID tags are capacitively coupled allowing RF signals to be communicated between RFID device and the one or more RFID tags in the container volume without being obstructed.

A tray (201) comprises electrically conductive material and has at least one hand-graspable fixture (203). This hand-graspable fixture comprises an electrical conductor (301) disposed in a location that is likely to be operably interacted with by a human who grasps the hand-graspable fixture. A capacitively-coupled RFID tag is then disposed on the hand-graspable fixture with a first antenna plate (303) being electrically coupled to the tray and a second antenna plate (304) that electrically couples to the electrical conductor. A corresponding tray receiving compartment (400) has a front lip (401) over which the tray must pass and upon which the tray will rest when properly disposed within the tray receiving compartment. One or more capacitively-coupled RFID tag reader antennas (402) are disposed proximal to the front lip. These antennas may be positioned to facilitate reading the capacitively-coupled RFID tag when the tray is properly disposed within the tray receiving compartment.

The present invention provides a multi-band, multi-mode RFID tag that uses a single antenna structure and integrated circuit to provide asset location information at any stage of a supply chain. The unified tag design operates at multiple frequencies (or bands) using the antenna structure, for example, 125 kHz, 13.56 MHz, 915 MHz, and 2.45 GHz, and preferably operates electrostatically (at lower frequencies) and electromagnetically (ay higher frequencies). An on-chip frequency monitor in the integrated circuit automatically determines which frequency is present and derives a local clock for the tag's integrated circuit, which can vary in accordance with the frequency or which can be constant. Alternatively, a phase locked loop circuit can be used to derive a local clock signal modulated into the interrogation signal. On-chip matching and power extraction circuits derive power for the tag from the interrogation signal, which is preferably passive. Additionally, a receiver can receive data from the interrogation signal.

An identifier of choice is correlated (102) with a predetermined task that potentially comprises a plurality of discrete human-enabled events. At least some of these discrete human-enabled events are then associated (104) with a corresponding capacitively-coupled radio frequency identification tag and the identifier then used (105) to monitor effectuation of the predetermined task. By one approach this monitoring comprises, at least in part, monitoring human-based task effectuation events via the capacitively-coupled radio frequency identification tags.

A method, apparatus, and system for performing facial recognition utilizing large databases is provided herein. During operation a large database is quickly narrowed by determining an automobile attribute (e.g., a license plate number) and determining a registered owner and possibly an address based on the automobile attribute. The image database is narrowed based on the registered owner of the vehicle, and possibly the address of the registered owner.

A method and apparatus for injury discovery and documentation includes a graphical touchscreen interface of the device operable to show a body image to allow a user to select an area of an injury on the body image and selectable indicia to allow a user to select a relative level of pain due to the injury. The injury information can then be provided for diagnosis and treatment. The device can also include an audio interface operable to determine a native language of the patient, and converse with the patient to ask the patient a set of questions relating to the area of the injury that are pre-stored in a memory of the device.
摘要:
Disclosed is a system for updating an RSSI-based map. A scanning devices notes which tags are seen during a scan and measures a “proxy distance” from the scanning device to each tag. When the scan is initiated, the scanning device measures the RSSIs from the local WAPs. The current location of the scanning device is determined by triangulating from the proxy distances of the scanned tags. That location is then correlated with the contemporaneously measured RSSIs. The correlation is used to update the RSSI-based map. In some embodiments, it is not the scanning device that measures the RSSIs. Instead, the WAPs measure the RSSIs from the scanning device whenever the scanning device transmits the results of a scan. In some embodiments, the operator of the mapped environment places scannable tags at fixed locations. Scans of these fixed-location tags are especially useful when determining the current location of the scanning device.

A radio frequency identification system comprising a radio reader circuit operable to emit a radio frequency carrier signal modulated with a subcarrier, which has a subcarrier modulation rate. The radio frequency identification tag circuit is operable to extract the subcarrier from the emitted radio frequency carrier signal and the extracted subcarrier then functions as a clock, which operates to assist in the transfer of a modulated backscattered signal to the radio frequency identification reader circuit. The radio frequency identification reader circuit decodes the modulated backscattered signal and the data encoded in the radio frequency identification tag circuit is obtained.

A method and apparatus for identifying a suspect through location and time events is provided herein. During operation a central server continuously receives updates from multiple networks regarding device identifiers and associated access points. When an event (e.g., a crime) occurs at a certain location, an access point(s) near the event are identified and devices associated with the access point(s) at the time of the event are determined. The identified devices are then utilized to determine potential suspects.
