Accuracy-enhanced scanner

摘要

An accuracy-enhanced scanner provides (in response to a first user input) illumination of potential scan targets and scans (in response to a second user input) a selected scan target. The user uses the illumination to aim the scanner at the selected scan target in between providing the first and the second user inputs. The scanner has switches to communicate the user inputs, to specify an operating mode for the scanner, and/or to communicate information codes to a computing device. The scanner has one or more scan engines (such as a barcode reader or an RFID tag reader), and optionally communicates wirelessly with the computing device. A scanning system including the scanner optionally provides feedback to the user based on feedback from a host processor. The scanner is any of a Multi-Mode Ring Scanner (MMRS), a cordless hand scanner, or a Personal Digital Assistant (PDA) with an add-on scanner.

主权项

1. A scanner comprising:
aiming circuitry enabled to illuminate a scan target with a pattern comprising at least one line in response to a first user input; scan-target imaging circuitry enabled to image the scan target in response to a second user input; and wherein the scanner is enabled to perform the illuminating and the imaging independently of each other and is enabled to initiate the illuminating prior to initiating the imaging.
