Abstract: A calibration process is started by a capacitive input variation when a capacitive button is pressed on a barcode reader. Or, the calibration process is started by the barcode reader scanning a configuration label or special label or barcode after the capacitive button on the barcode reader is inoperative. The calibration process realigns the input and the threshold to correctly configure the capacitive button.

Abstract: An optical scanner captures a plurality of images from a plurality of image-capture devices. In response to the activation signal, an evaluation phase is executed, and in response to the evaluation phase, an acquisition phase is executed. In the evaluation phase, a first set of images is captured and processed to produce a virtual frame comprising a plurality of regions, with each region containing a reduced-data image frame that is based on a corresponding one of the plurality of images. Also in the evaluation phase, attributes of each of the plurality regions of the virtual frame are assessed according to first predefined criteria, and operational parameters for the acquisition phase are set based on a result of the assessment. In the acquisition phase, a second set of at least one image is captured via at least one of the plurality of image-capture devices according to the set of operational parameters.

Abstract: A data reading system for predicting the removal of a data reader from a charging base unit based on the approach of a user's hand. The data reading system includes a data reader with a power supply, a base unit configured to receive the data reader and to charge the power supply of the data reader responsive to the data reader being coupled to the base unit, a sensor configured to detect the approach of a user's hand, and a processor in operable communication with the sensor and the data reader or the base unit. The processor is configured to apply an appropriate action, such as adjust an amount of current used to charge the power supply of the data reader in the base unit responsive to the sensor detecting the approach of the user's hand.

Abstract: Method and device for detecting and classifying a not-known object by a device having a two-dimensional field of view. The method includes a learning step, a detecting step and an inspection step. The learning step includes positioning a first known object in a field of view of the device and then positioning a second known object in the field of view of the device, to obtain images of the first and second known objects. Distinctive characteristics and common characteristics of the objects are identified and used to obtain an equality descriptor relative to common elements of the first and second known objects and a difference descriptor allowing association of the first and second known objects to two distinct classes. The device is then used to detect a third, not-known object. The equality descriptor and the difference descriptor are then used in an inspection step to classify the third not-known object.

Abstract: Systems and methods for applying and detecting cross dependent marks incorporated into an electronic or digital image to form a watermark. The electronic or digital image may include encoded information for example a machine-readable symbol. The watermarking may include an encoding and insertion sub-process that inserts one or more marks into an image at a first point in time for form a marked image, an extraction sub-process that extracts the marks at a second point in time, and a detection sub-process 108 that determines if any modifications have been made to the marked image. The marked image may be formed by determining a first original descriptor and first original mark within the image, determining a second original descriptor and second original mark within the image, and incorporating the first original mark into the second original descriptor and incorporating the second original mark into the first original descriptor.

Abstract: A device for focusing a light beam comprises a optical assembly comprising at least one focusing lens and/or mirror, a support structure which supports the optical assembly, a magnetic actuator configured to move the optical assembly with respect to the support structure along a moving direction substantially parallel to an optical axis (X) of the optical assembly and at least one position sensor configured to provide an indication of the position of the optical assembly with respect to the support structure. The magnetic actuator comprises at least one permanent magnet integrally associated with the optical assembly and at least one first electrical winding integrally associated with the support structure and configured to cause flowing of an electric current within it, wherein the electrical current interacts with said at least one permanent magnet and causes the movement of the optical assembly along said moving direction until the optical assembly is brought to a desired focusing position. The focusing device comprises at least one second electrical winding integrally associated with the support structure and configured to be short-circuited so as to generate, due to the electromagnetic induction generated by the relative motion between said at least one permanent magnet and said at least one second electrical winding, a braking force that opposes the movement of the optical assembly along said moving direction.

Abstract: A system and method for matching a pattern may include generating a set of model descriptors representative of segment features of a first imaged object. A set of query descriptors representative of segment features of a second imaged object may be generated. A first model segment may be selected to align with the query segments to determine if any of the query segments correspond with the first model segment based on respective model descriptors and query descriptors. An hypothesis may be generated by computing a transformation to match the selected first model descriptor with a query descriptor. The hypothesis may be validated by a model fitting algorithm when comparing other transformed model descriptors with other query descriptors. Based on a consensus value from the model fitting algorithm, a determination as to whether a pattern match exists between the first and second images may be made.

Abstract: A wireless power system providing protection from overvoltage conditions. A wireless power receiver has one or more magnets to allow detection of a distance of the wireless power receiver from a wireless power transmitter using a Hall effect sensor. When the detected distance is less than a determined threshold, the wireless power transmitter is instructed to transmit power. The wireless power receiver has one or more transient voltage suppression (TVS) diodes communicatively connected so that when a determined operating voltage of a protected portion of the receiver is exceeded, the TVS diodes provide a low impedance path for transient current to divert the transient current away from the protected portion of the receiver. When the wireless power receiver detects an overvoltage condition, the receiver sends a reset command to the wireless power transmitter.
