Abstract:
PROBLEM TO BE SOLVED: To determine the shape of a glass sheet during and/or after the forming process. SOLUTION: The system 26 for determining the shape of the glass sheet 24 for planning an interior bulk is provided with: a laser 38 configured to direct the laser beam 40 toward the glass sheet 24 at a predetermined angle along projection vector; an image capture device 30; and a processor 32 configured to calculate the location of an energy centroid within a selected portion of the bulk of the glass sheet 24. The laser beam 40 has a selected wavelength sufficient to cause an interior portion of the glass sheet 24 through which the laser beam 40 propagates to fluoresce and emit a fluorescent light energy. The image capture device 30 is configured to receive the fluorescent light energy and image the fluorescent light energy on the sensor 54. The sensor 54 generates a position signal based on a position of the imaged fluorescent light energy thereon. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
Excess radio-frequency (RF) power storage and power sharing RF Identification (RFID) tags, and related RFID tag connection systems and methods are disclosed. The excess RF power storage and power sharing RFID tags and related RFID tag connection systems and methods in embodiments disclosed herein allow connected RFID tags to store excess energy derived from excess received RF power in a shared energy storage device. In this manner, an individual RFID tag or a group of connected RFID tags in the RFID tag connection system can continue operation during temporary times when sufficient RF power is not being received from a RFID reader. Sharing stored energy derived from excess received RF power in a shared energy storage device among connected RFID tags in a RFID tag connection system can significantly mitigate problems of RF power interruption.
Abstract:
Disclosed herein are radio-frequency identification (RFID) tag event occurrence detection, generation, and monitoring. Related components, RFID readers (34), systems (10), and methods are also disclosed. The RFID tags (12) are configured to sense an event(s) that occurred in the RFID tag (12) or in proximity thereto. In response, the RFID tags (12) are configured to set an event occurrence indicator(s) (22) in a memory (22) of the RFID tag indicating the occurrence of the sensed event(s). A RFID reader (34) is configured to perform a query of a population of RFID tags (12) in communication range to detect which RFID tags have a set event occurrence indicator(s) (22), so a RFID reader (34) can then specifically communiate with RFID tags (12) that experienced an event(s) to request and service the event(s) type without having to perform those same operations for the entire RFID tag population. The RFID reader (34) can be configured to take desired actions based on detection of events.
