Methods and systems receive location identification tokens from transmitters using a portable computerized device. A first location identification token is received from a first location transmitting device, while the portable computerized device is within a predetermined distance from a designated location. A second location identification token is received from a second location transmitting device. A current location signature is calculated using the first and second location identification tokens. A previously stored location signature associated with the first and second location identification tokens is obtained from a computer readable storage medium. The current location signature is compared with the previously stored location signature to determine a similarity measure. The location identification tokens and the current location signature are stored in a memory and transmitted to a server. The presence of the portable computerized device at the designated location is verified based on the location identification tokens and the current location signature.

A barcode scanner system includes a scan unit which includes, on one surface thereof, a scan module for scanning a barcode and has, on the other surface thereof, a structure for coupling to a body unit; and the body unit which has one surface having a shape corresponding to the coupling structure of the scan unit, and includes a display module, a communication module, an operation module, and a fingerprint recognition module. The body unit recognizes fingerprint information of the user through the fingerprint recognition module, and transmits the fingerprint information to a server to perform authentication. When a user input to the operation module occurs after authentication completion information is received from the server, a barcode scan is performed, and the scanned barcode information is transmitted to the server. Barcode information and user information identified through recognition of the fingerprint information are matched and stored in the server.

Transport of physical objects is controlled based on scanning of encoded images. In one approach, an encoded image on a physical object is scanned to obtain parameters. The parameters include specifications for a product to be made by a manufacturing process. One or more rules are generated using the parameters and then stored in a database. The database is queried to determine whether the product conforms to the one or more rules. For example, the query may include data regarding characteristics of the final product and/or the manufacturing process. In response to determining that the product conforms to the rules, the product is transported to a distribution facility.

A computer system for decoding a signal of decodable indicia is disclosed. The computer system includes a laser scanner configured that outputs a signal of decodable indicia and a microprocessor that include a camera sensor interface that is configured to receive the signal from the laser scanner.

A system for verifying the authenticity of a printed mark includes an image acquisition device that acquires an image of a printed mark. In one implementation, the printed mark includes an identifier that identifies the group or class of an item to which the printed mark is to be (or has been) attached. The system may also include one or more processors that carry out actions such as receiving the image from the image acquisition device; analyzing the image to identify artifacts in the printed mark, retrieving a genuine mark signature from a data storage containing genuine mark signatures, comparing the identified artifacts with the genuine mark signature, and determining whether the unverified item is authentic based on the comparison.

An encoded information reading (EIR) terminal can comprise a microprocessor, a memory, an EIR device including a two-dimensional imager, and a micro-projector including a light source and a light manipulation sub-system. The EIR device can be configured to output raw message data containing an encoded message and/or output a decoded message corresponding to an encoded message. The EIR terminal can be configured to acquire an image of a target object in a field of view (FOV) of the two-dimensional imager. The EIR terminal can be further configured, responsive to successfully locating decodable indicia within the image, to produce a decoded message by decoding the decodable indicia. The EIR terminal can be further configured, responsive to successfully decoding the decodable indicia, to generate a projectable image and to project the projectable image onto a surface the target object using the micro-projector.

An audio signal control apparatus includes a sound input circuit, a sound output circuit, and a control circuit. The sound input circuit is configured to receive an ambient sound signal from a microphone that captures ambient sound. The sound output circuit is configured to generate an output sound signal and transmit the output sound signal to a speaker to generate sound based on the output sound signal. The control circuit is configured to determine characteristics of the ambient sound based on the ambient sound signal received by the sound input circuit, determine a frequency band of the sound to be generated by the speaker based on the characteristics of the ambient sound, and control the sound output circuit to generate an output sound signal corresponding to the sound of the determined frequency band.

A bioptic barcode reader is disclosed for selective use of illumination color to capture appropriate data. The bioptic barcode reader includes a housing and a primary imager positioned within the housing, configured to scan a target object during a first time period. The bioptic barcode reader further includes a primary illumination source positioned within the housing configured to emit primary illumination in a primary wavelength range during the first time period. The bioptic barcode reader further includes a secondary imager configured to capture one or more images of a target object during a second time period. The bioptic barcode reader further includes a secondary illumination source configured to emit secondary illumination in a secondary wavelength range during the second time period, wherein the second time period and first time period are interleaved and the secondary wavelength range is different from the primary wavelength range.

A barcode reader includes an illumination assembly configured to illuminate a target; an imaging assembly configured to capture an image of the target, and a visual indicator assembly that includes: a projection lens; a first light source configured to emit first color light through the projection lens to project an aim pattern onto the target; a second light source configured to emit second color light through the projection lens to project a visual indicator onto the target; and an optical element configured to direct the light from both the first light source and the second light source to the projection lens. A memory and a processor of the barcode reader are configured to cause the first light source to emit light prior to the imaging assembly capturing the image; and cause the second light source to emit light subsequent to the processor successfully decoding a symbology in the captured image.
