This patent specification describes a barcode-reading enhancement accessory for a mobile device having a barcode-reading capability. The accessory may include an outer case and an inner carriage. A mobile device is encased in the inner carriage, and the combination of the inner carriage and the mobile device may be accommodated in the outer case. The inner carriage is configured to accommodate a mobile device of a particular size such that a mobile device of a different size may be accommodated in the outer case using a different inner carriage. The accessory may also include an optic system to fold an optical path of a field of illumination of a light source of the mobile device and/or a field of view of a camera of the mobile device.

A data reader for reading and decoding a code from an item. The data reader includes an imager operable to form an image of the code from an item located in a field of view of the data reader. The data reader further includes an illumination system including optics arranged to direct light from one or more illumination sources along one of a variety of different optical paths to illuminate the field of view of the data reader with one of a plurality of light patterns. The data reader also includes an active element controllable to selectively direct the light along one of the optical paths.

The techniques described herein enable a head-mounted display device to use a fiducial marker to identify an Internet of Things (IoT) device. The head-mounted display device can use the identifier to establish a network connection with the IoT device. For example, the identifier can include an Internet Protocol (IP) address, a Bluetooth address, a cloud IoT identifier (e.g., AZURE hub IoT identifier), or another type of an identifier. By using an electronic paper display, the IoT device can dynamically generate and display a new fiducial marker when a new identifier is assigned to the IoT device or is generated by the IoT device. Consequently, the head-mounted display device can detect the fiducial marker and extract the identifier for the IoT device from the fiducial marker so that the identifier can be used to establish a network connection with the IoT device.

An imaging sensor of an imaging reader senses return light from a target to be read by image capture along an imaging axis over a field of view that extends along mutually orthogonal, horizontal and vertical axes. Two aiming light assemblies are offset from the sensor, and direct an aiming light pattern at the target. The pattern has an aiming mark in a central area of the pattern, and a pair of aiming light lines that are collinear along the horizontal axis. The visibility of the aiming mark is enhanced by optically configuring the aiming mark to be different in brightness and/or color and/or size and/or state of existence relative to a remaining area of the pattern. The aiming mark of enhanced visibility constitutes a prominent visual indicator of a center zone of the field of view.

A method for controlling a character and barcode recognition apparatus by receiving an image including at least one text image and at least one barcode, dividing the received image into a text area and a barcode area, the text area including the at least one text image and the barcode area including the at least one barcode, recognizing at least one character in the text area by performing character recognition on the text area, and recognizing the at least one barcode in the barcode area by performing barcode recognition on the barcode area.

A smart glove includes a glove for housing and triggering electronic modules having a sensor; a triggering member for triggering the electronic modules; and a slide provided on the glove for partially or completely enclosing the electronic modules. The slide is made of a flexible material and comprises a base; two side walls extending from two side portions of the base; two channels extending starting from a first end of the base towards a second end of the base; a protrusion connected to the base from a connection end of the protrusion and extending between a channel; a lock end located at an end of the protrusion not connected to the base and extending from the protrusion perpendicularly or in an angled manner; a slot provided on an opposite end of the base without the lock end, comprising a hollow and extending from the base towards a roof.

A reading apparatus includes a wireless tag reader including an antenna and an antenna surface facing a first direction and through which the antenna emits a radio wave to read tag information from a wireless tag, and a code reader including an imaging unit and an imaging window facing the first direction and through which the imaging unit acquires an image to read a code. The code reader further includes a grip detachably connected to the wireless tag reader.

A reading device according to an embodiment includes a scanner configured to read code information indicated by a code symbol, a holder configured to detachably hold the scanner, a detecting unit configured to detect a first state in which the scanner is held by the holder and a second state in which the scanner is detached from the holder, and a setting-condition changing unit configured to, if the detecting unit detects the second state, set setting conditions relating to the reading by the scanner such that a reading distance of the scanner is shorter than the reading distance in the first state.

A screen display ratio adjusting apparatus includes a handheld device and a display device. The handheld device includes an application module which obtains an image of a pre-stored picture being displayed on a display interface of the display device (“test picture”). The pre-stored picture includes a first section and a second section. The application module calculates respective lengths and widths of the first and second sections from the test picture. The application module further calculates a display size ratio between the first section and the second section, and adjusts a display size of the first section. The display device is then configured to display the first section in an adjusted size. A screen display ratio adjusting method is also provided.

A scanner for machine-readable symbols, such as barcodes and two-dimensional matrix symbols, employs at least two different light frequencies (colors). The first frequency supports accurate aiming of the scanner at a symbol. The second frequency supports illumination of a machine-readable symbol so that the reflected illumination light can be read at the second frequency by the scanner's optical imaging element. Employing two different light frequencies enables both aiming and scanning to occur simultaneously, while the aiming process does not interfere with the scanning process. It enables the aiming frequency to be used for additional purposes, such as providing signaling to a user of the scanner. In an embodiment, two distinct light sources are used in the scanner to provide the different light frequencies. In an embodiment, various color filters are employed to separate and distinguish light frequencies. In an embodiment, signal processing may be employed to digitally distinguish multiple separate frequencies in light reflected from the symbol.
