Abstract: In an optical sensing system, illumination light is selectively emitted by an illumination system at a selected wavelength from among a set of available wavelengths including a first wavelength, and a second wavelength that is different from the first wavelength, to illuminate a target area. The portion of the emitted light that is reflected from the target area is received by a photosensor that is sensitive in a range that includes the first wavelength and the second wavelength. A preferred at least one wavelength of the selective light emission is autonomously selected from among the first wavelength and the second wavelength based on assessed comparative performance of the photosensor in conjunction with the emitted light of the first wavelength and of the second wavelength in currently prevailing conditions.

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: An optoelectronic device, e.g. of a photocell or light barrier, comprising an electrical-to-optical or optical-to-electrical transducer, and an optical tube assembly comprising an optical chamber, a first aperture proximal with respect to the transducer, and a second, distal aperture being formed in chamber wall. In at least one first half-section taken e.g. along optical axis, at least an intermediate portion of the chamber wall extending between a first and a second line has a local tangent at each point (P) oriented so that any stray light ray incoming from the boundary point of the first aperture in the opposite half-section would be so deviated at that point (P) as to impinge upon the chamber wall at an impingement point (Q) in said first halfsection and more distal than the distal line.

Abstract: A wireless charger adapter may include a structural member, a receive inductor coil supported by the structural member, an electrical circuit, and an output. The structural member may be placed in proximate location with a cradle of a wireless charging device inclusive of a transmit inductor coil. The receive inductor coil may inductively receive wireless power signals inductively transferred by the transmit inductor coil of the wireless charging device. The electrical circuit may convert the wireless power signals received by the receive inductor coil into electrical signals and the output may output the electrical signals from the electrical circuit to one or more external devices.

Abstract: A system and method are described herein for controlling optical power provided to one or more laser projectors of an image capture device, such as a stereo camera, for improving depth image acquisition and quality while adhering to eye safety standards based on laser emissions. The system includes one or more laser projectors operable to emit a laser dot pattern onto a scene, and image capture devices operable to capture images from the scene including the laser dot pattern. The images are analyzed to acquire depth information for objects in the scene, and the depth information is used to modulate the optical power of the laser projectors based on the distance to the object relative to the image capture device.

Abstract: The disclosure relates to a system and method for verifying robot data that is used by a safety system monitoring a workspace shared by a human and robot. One or more sensors monitoring the workspace are arranged to obtain a three-dimensional view of the workspace. Raw data from each of the sensors is acquired and analyzed to determine the positioning and spatial relationship between the human and robot as both move throughout the workspace. This captured data is compared to the positional data obtained from the robot to assess whether discrepancies exist between the data sets. If the information from the sensors does not sufficiently match the data from the robot, then a signal from the system may be sent to deactivate the robot and prevent potential injury to the human.

Abstract: A computer-implemented method of performing a three-dimensional 3D point cloud registration with multiple two-dimensional (2D) images may include estimating a mathematical relationship between 3D roto-translations of dominant planes of objects in a 3D point cloud and bi-dimensional homographies in a 2D image plane, thereby resulting in a 3D point cloud registration using multiple 2D images. A trained classifier may be used to determine correspondence between homography matrices and inferred motion of the dominant plane(s) on a 3D point cloud for paired image frames. A homography matrix between the paired images of the dominant plane(s) on the 2D image plane may be selected based on the correspondence between the inferred motions and measured motion of the dominant plane(s) on the 3D point cloud for the paired image frames. The process may be less computationally intensive than conventional 2D-3D registration approaches.

Abstract: A system and method of detecting an image of a template object in a captured image may include comparing, by a processor, an image model of an imaged template object to multiple locations, rotations, and scales in the captured image. The image model may be defined by multiple model base point sets derived from contours of the imaged template object, where each model base point set inclusive of a plurality of model base points that are positioned at corresponding locations associated with distinctive features of the imaged template object. Each corresponding model base point of the model base point sets may (i) be associated with respective layers and (ii) have an associated gradient vector. A determination may be made as to whether and where the image of the object described by the image model is located in the captured image.

Abstract: An automated point of sale system uses one or more cameras to capture images of food products selected by a user for purchase at a food establishment. The point of sale system then compares the images captured to previously captured reference images of such food products being offered at the establishment to find a match for each product, determines the price of each food product the user has selected based on the comparison and match, identifies an account of the user based on a biometric identification of the user and/or reading information from a machine readable token of the user, and automatically causes the account of the user to be charged or debited for the food products identified, thus reducing the check-out time and increasing efficiency of food establishment point of sale systems.
