Abstract:
Systems and methods involving one or more wearable components that obtain information about a surrounding environment and provide information to a user to assist user in retrieving objects from the surrounding environment. The information may include navigation information related to a route that the user may take to retrieve an object, as well as information about the object to be retrieved. The wearable components may be include ones that may be mounted on the head of the user, as well as components that the user may wear on other parts of the body or that attach to clothing. The wearable components may include image sensors, microphones, machine-readable symbol readers, range-finders, accelerometers, and/or gyroscopes that may collect information from and about the surroundings of the user. The wearable components may also include one or more of a set of speakers and/or a display subsystem to provide information to the user.
Abstract:
A code reader may include a light source configured to illuminate a target area in which items are to be located for reading machine-readable indicia associated with the items, an image sensor configured to capture an image of the target area, an illumination drive circuit in electrical communication with the light source, and an image capture circuit. The image capture circuit may be configured to (i) enable and disable the image sensor to capture an image of the target area during the high illumination and a portion(s) of the low illumination of the target area, and (ii) read an image captured by the image sensor. The illumination drive signals may cause the illumination drive circuit to generate a high illumination drive signal to cause the light source to produce a high illumination, and generate a low illumination drive current to cause said light source to produce a low illumination.
Abstract:
The present disclosure relates to data readers (5) including an improved imaging system (10) that optimizes active and passive autofocus techniques for improving data reading functions. In an example, the data reader initially uses active autofocus techniques to focus a lens system (14) based on a measurement reading by a rangefinder (22) and acquire an image of an item in the field-of-view of the data reader. The data reader includes a decoding engine (42) operable to decode an optical code of the item using the acquired image. If the decoding engine is unable to decode the optical code using the active autofocus technique, the data reader alternates to a passive autofocus technique to alter the focus settings of the lens system (14) and reattempt the decoding process.
Abstract:
The present invention refers to a fixed position reader (10) of coded information comprising a housing (11) provided with a reading window (15) having a peripheral rim (15a), said housing (11) comprising a device (12) for reading coded information which generates a reading field projecting through the reading window (15) towards the outside of the housing (11), and a device (17) for visually indicating the reading result to a user, which is characterized in that said visual indication device (17) generates a visual indication (18) appearing substantially on the reading window (15) and/or on at least a portion of the peripheral rim (15a) of the reading window (15) and/or on at least a portion (11a) of the housing (11) adjoining laterally the peripheral rim (15a) of the reading window, said housing portion (11a) being on the left and/or right side of the reading window (15) and/or below the reading window (15). The present invention further refers to a camera based checkout security system (20) comprising at least a checkout security camera (21) and a fixed position reader (10) of coded information as described above, wherein the checkout security camera (21) generates a camera field of view directed towards a reading window (15) of the fixed position reader (10) of coded information.
Abstract:
Coded information reader (1) for reading coded information (6) from an object, comprising a first camera assembly (10) having a first resolution, a first frame rate and a first field of view (18), and a second camera assembly (20) having a second resolution, a second frame rate and a second field of view (28), wherein the first resolution is lower than the second resolution and the first frame rate is higher than the second frame rate. The first camera assembly (10) is configured to acquire frames and to process the acquired frames to perform: - detection of object presence, - determination of operating parameters for both the first camera assembly (10) and the second camera assembly (20), - coded information decoding, - in case of failure of said coded information decoding, triggering of the second camera assembly (20) to acquire frames and to process the acquired frames to perform coded information decoding with the operating parameters set as determined by the first camera assembly (10) for the second camera assembly (20).
Abstract:
A flexible cable may include an electrical conductor, a dielectric insulator layer surrounding the electrical conductor, a jacket layer being flexible and surrounding the dielectric insulator layer, a shield surrounding the dielectric insulator layer and a connector electrically connected to the electrical conductor. The connector may be configured to connect to an electronic device and communicate electrical signals from the electrical conductor to the electronic device. The cable may further include a capacitive layer engaging the jacket layer. At least one capacitive pad may be disposed on the capacitive layer and be configured to communicate signals (e.g., capacitance variance) over a communications path in response to a user touching the capacitive pad(s) by his or her fingers.
