摘要： An integrated optical module for an optical scanner has a lens spaced from a vertical-cavity surface-emitting laser (VCSEL) by a spacer of defined dimensions. The module, in an alternative embodiment, includes a wafer frame, a suspended mirror mounted for oscillation on the frame, a wafer substrate bonded beneath the frame and a wafer cover bonded above the frame. The cover includes a mirror travel stop to protect the mirror against shocks. A VCSEL mounted to the wafer cover produces a beam which is shaped and deflected by a diffractive optical element onto the oscillating mirror. The reflected beam passes out of the module toward an indicia to be read. Large numbers of such devices may be fabricated relatively cheaply using wafer-scale processing and assembly technology. Three large wafers are fabricated corresponding respectively to arrays of substrates, frames and covers. The large wafers are bonded together in a sandwich arrangement, and are then diced to produce the individual scan modules. The modules may provide either one-dimensional or two-dimensional scanning.

摘要： An arrangement for determining light beam position in an electro-optical reader, image projector and like devices includes a drive for moving a scanning light beam at a scan frequency across a target as a scan line, and an electro-optical feedback assembly operatively connected to the drive, for optically detecting scan line position during beam movement, and for generating a feedback signal at the scan frequency, the feedback signal being indicative of the scan line position.

摘要： A technique for operating a Radio Frequency Identification, RFID, reader with motion detection includes detecting a motion in proximity to the RFID reader, and triggering the RFID reader to read any tags in proximity to the RFID reader in response to detecting a motion in proximity to the RFID reader. Detecting a motion can also generate a change in digital signage, or communicate information about read tags to a local area network. Operating this system only when motion is detected saves battery life.

摘要： The present disclosure describes a system, methods and apparatus for displaying read range of a nomadic Radio Frequency Identification (RFID) reader based on feedback from fixed RFID beacon tags. For instance, the nomadic RFID reader can transmit an interrogation signal within a space that includes a plurality of fixed RFID beacon tags at known locations, and can receive response signals from a group of the fixed RFID beacon tags. Based on known locations of the group of fixed RFID beacon tags, a read range of the RFID reader can be determined. The read range is defined by the group of the fixed RFID beacon tags. The read range of the nomadic RFID reader can then be displayed on a display along with other information about the fixed RFID beacon tags and/or RFID item tags that are within the read range of the nomadic RFID reader.

摘要： An integrated scanner for scanning a barcode is formed on a common substrate. The scanner may include a micro-machined mirror, a laser diode, and a detector, mounted on a single substrate or several connected substrates. Lenses can be used to focus a laser beam from the laser diode as well as expand a laser beam deflected by the micro-machined mirror. The scanner may also scan a barcode without using a micro-machined mirror by rotating the laser diode.

摘要： The laser diode of an optical scanning system is located in a separate unit and light therefrom carried to a remote scan head via an optical fiber. This reduces the size and weight of the scan head and reduces the temperature sensitivity of the scan head. The scan head may include an optical sensor for detecting light reflected from scanned symbols. Alternatively, the separate unit may house the sensor, and the same fiber or an additional fiber will collect the reflected light and transmit that light back to the sensor. The invention also encompasses a number of electromagnetic and piezoelectric systems for producing a scanning motion of the beam emitted by the scan head.
