Abstract: Method and apparatus for automatically reading bar code symbols using an automatic hand-holdable bar code symbol reading device (2) comprising a housing (5) containing operative elements which provide an object detection field and scan field defined external to said housing (5). Such an arrangement detects the presence of an object, in the object detection field, by sensing the IR radiation reflected off of the object, irradiated by a source disposed in the housing (5). In automatic response of detection of the object, the device detects the presence of a bar code in the scan field using a laser (28) disposed in the housing (5). Then in automatic response to detecting the bar code, the bar code is scanned and scan data signals are produced in response in order for bar code data to be read, collected and processed.

Abstract: Disclosed is a fully automatic bar code symbol reading system having at least one automatic (i.e., triggerless) portable bar code symbol reading device, and an associated base unit positioned within the data transmission range thereof without a physical wiring connection thereto. After each successful reading of a bar code symbol, the bar code symbol reading device automatically produces symbol character data representative of the decoded bar code symbol, synthesizes a group of data packets each containing the symbol character data, and then transmits the synthesized group of data packets to the base unit. Upon the successful receipt of one of the transmitted data packets and the recovery of symbol character data therefrom, the base unit generates an acoustical acknowledgement signal that is perceptible to the user of the bar code symbol reading device and indicates the transmitted symbol character data has been successfully received. In typical applications, a plurality of such bar code systems are used in physical proximity with each other, such as in conventional retail point-of-purchase (POS) environments. In accordance with the present invention, radio frequency(RF) carrier signals of the same frequency are used by each hand-supportable bar code symbol reading device to transmit groups of data packets to respective base units.

Abstract: A scanner determines whether a target is a bar code symbol and, if so, whether that symbol is one-dimensional or two-dimensional. For two-dimensional symbols, the scanner aligns a scanning pattern with the symbol and expands the scanning pattern to reach only to the top and bottom edges of the symbol, not beyond. The scanner also has a microprocessor-control scanning engine that uses a coil to drive a scanning element and pick up feed back signals from the scanning element. A pulse-width-modulated regulator also provides fast and efficient operation for driving the coil. The scanning engine can also be designed to generate a pattern that precesses across the target, and a powerful interface to the scanning engine allows decoding and control logic to work efficiently with and independently of the scan engine.

Abstract: A data capture terminal for, and a method of, processing a plurality of data and a symbol arranged at spaced-apart locations on a target, such as a parcel delivery label, employ a solid-state imager having an array of image sensors for capturing return light from the data and the symbol on the target over a field of view, an actuator for actuating the imager to capture the return light from the data and the symbol on the target in a single actuation, and a controller operatively connected to the actuator and the imager, for processing the return light captured by the imager from the plurality of data and the symbol. The terminal is customized by a user program that advises the controller of user-selected parameters and conditions under which the processing of the return light is to be performed.
