摘要： The disclosure a barcode reader having a feedback device for providing tactile feedback to the user through the trigger button. The feedback device may be disposed within the housing and in cooperation with the trigger button. The feedback device may be configured to provide tactile feedback related to the barcode read to the user through the trigger button via a resistance impressed upon to the trigger button in a first instance, and a release of the resistance to the trigger button in a second instance.

摘要： A machine-readable symbol reader can capture a cubic data set of an object carrying a machine-readable symbol. The machine-readable symbol reader can include a hyperspectral sensor, and the cubic data set may include image data for the machine-readable symbol within multiple, different wavelengths of the electromagnetic spectrum. The cubic data may be separated into portions that are each analyzed by specific processors, and those separate analyses can be used to increase the capabilities and efficiency compared to known machine-readable symbol readers.

摘要： A code reader comprises a first imager and a second imager configured to capture an image with different field of views, a first illuminator and a second illuminator configured to project a different illumination pattern, and a processor operably coupled to the imagers and the illuminators. The processor configured to activate the first imager and the first illuminator as a receiver pair responsive to detecting a first condition, activate the second imager and the second illuminator as a receiver pair responsive to detecting a second condition, and decode an optical code using an image captured by the selected receiver pair.

摘要： Systems and method for remotely capturing a barcode and local decoding. The barcode may be captured using a remote imaging sensor. Images captured may be transmitted to a mobile scanner with an incorporated decoder. Additionally, inputs to the mobile scanner may facilitate moving the remote imaging sensor in three-dimensional space. Some embodiments also include a pointer device that may non-destructively mark a position for the remote imaging sensor to target. An image or series of image may be transmitted to the mobile scanner. When an image includes a barcode, the mobile scanner may decode the barcode and provide confirmation feedback.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
