摘要:
An apparatus for measuring surface topography of an object includes an optical arrangement capable of directing a first light beam at a surface of the object, providing a second light beam coherent with and spatially phase-shifted relative to the first light beam, and generating an interference beam from the second light beam and a reflection of the first light beam from the surface of the object. The apparatus further includes at least one line scan sensor for detecting and measuring the interference beam.

An active mirror guidance system for a vehicle is disclosed. The guidance system includes active mirrors to track a target. The mirrors are moved in response to disturbances detected by sensors or manually via remote control. The image provided from the mirrors is sent to a focus device for processing. A signature signal processing device and additional optics may also be used. A control system connects each of the components of the guidance system. The guidance system is also connected to the vehicle control equipment to steer the vehicle toward the target.

Disclosed are systems and methods for determining the shape of a glass sheet during and/or after the forming process. In one example, a system for determining the shape of a glass sheet defining an interior bulk can include a light source, an image capture device and a processor that are configured to calculate the location of an energy centroid within a selected portion of the bulk of the glass sheet.

Disclosed herein are radio-frequency identification (RFID) tag event occurrence detection, generation, and monitoring. Related components, RFID readers, systems, and methods are also disclosed. The RFID tags are configured to sense an event(s) that occurred in the RFID tag or in proximity thereto. In response, the RFID tags are configured to set an event occurrence indicator(s) in a memory of the RFID tag indicating the occurrence of the sensed event(s). A RFID reader is configured to perform a query of a population of RFID tags in communication range to detect which RFID tags have a set event occurrence indicator(s), so a RFID reader can then specifically communiate with RFID tags 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 can be configured to take desired actions based on detection of events.

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.
