摘要:
A microprocessor and an application specific integrated circuit are embodied as two chips mounted on a printed circuit board which is, in turn, mounted on a scan engine for use in an electro-optical reader. This dual chip architecture is readily configurable and controls reader operation.

An electronic device includes an imaging sensor collecting an image and creating an imaging signal corresponding to the image, an integrated circuit receiving the imaging signal from the imaging sensor and modifying a transfer characteristic of the imaging signal and a connector receiving the imaging signal from the integrated circuit having the modified transfer characteristic.
摘要:
A system and method for processing scanner signals by storing both a standard digitizer signal and a more detailed digitizer signal for decoding. The decoder can then use the standard digitizer signal by default and in those cases when the bar code pattern cannot be decoded using the standard digitizer signal the decoder may access the more detailed digitizer signal.

The operating condition of data capture systems, such as electro-optical readers, RFID readers, and imagers, is monitored and reported to a host which preferably modifies the operating condition when the latter is outside a preestablished setting.

An imaging assembly in an imaging reader for electro-optically reading indicia includes a solid-state imager having an array of image sensors, and a focus control element, such as a liquid imaging lens, having a variable transfer function characteristics for capturing, optically modifying and directing return light from the indicia over a field of view onto the imager for processing into an electrical signal indicative of the indicia during a reading mode of operation; and a controller for controlling the imaging assembly to optically modify the return light in accordance with a known transfer function stored in a memory accessible to the controller during a calibration mode of operation prior to the reading mode.

A method and apparatus for imaging targets with an imaging reader. The method includes: (1) capturing return light from a target over a field of view of the solid-state imager and generating image data corresponding to the target; (2) transmitting the image data from the solid-state imager to the host when the gate circuit is set to the transmitting mode; and (3) preventing the image data from transmitting to the host when the gate circuit is set to the blocking mode.
摘要:
Laser power control arrangements interrupt power to a laser used in electro-optical readers upon detection of an over-power condition not conforming to preestablished regulatory standards. In one embodiment, during an operational mode, a difference between laser drive currents at two operating points is compared to a difference between laser drive currents at the same two operating points during a calibration mode. The over-power condition is recognized when the difference during the operational mode exceeds the difference during the calibration mode by a predetermined amount. In another embodiment, the laser is only energized to emit the beam at a reduced power level well below regulatory standards for staring at even if a motor drive failed.
