摘要： An electronic device includes a movable assembly. An optical proximity sensor is disposed on the movable assembly. The movable assembly may be spaced from a fixed assembly on the electronic device, and the movable assembly can move on a plane that is disposed in parallel relative to the fixed assembly. A light intensity of light that is from the optical proximity sensor and that is reflected by the fixed assembly may reflect a position of the movable assembly relative to the fixed assembly. Whether the movable assembly moves to a specified target position may be determined based on the light intensity of the light that is reflected by the fixed assembly and that is detected by the optical proximity sensor.

摘要： An emitter and a receiver in a light barrier system are aligned by placing one or more retroreflective elements in a vicinity of the receiver such that a beam of visible light emitted by an optical alignment element impinges on a retroreflective element when the light beam emitted by the emitter impinges on the receiver. The optical alignment element is activated to emit a beam of visible light, and optical components of the system are adjusted so that the visible beam emitted by the optical alignment element impinges on, and is reflected by, the retroreflective element.

摘要： The invention relates to a light barrier system, comprising at least two reflection light barrier devices, each of which is configured to emit a light beam and to detect a reflected light beam, wherein the light barrier system comprises a reflection body, which is configured to reflect back light beams emitted from at least two different directions in parallel, which are spaced apart at an angle of at least 20°, wherein the at least two reflective light barrier devices are arranged in such a way that they emit light beams from different directions onto the same reflection body in order to monitor at least two spatially different areas. In a further aspect, the invention relates to the use of a reflection body.

摘要： Method, apparatus, and non-transitory computer readable media for detecting reel-crop engagement for a header of a harvester. The header includes a reel configured to draw crop from a crop field toward the header as the harvester moves through the crop field and at least one crop detector mounted to the reel. Data is received from the at least one crop detector mounted on the reel, processed, and used to detect reel-crop engagement.

摘要： Embodiments are directed towards a safety system that can be used with a high-flux power beam, such as in wireless power transmission. The system includes a transmitter that generates and transmits a power beam and a receiver that receives the power beam. A plurality of sensors is configured to independently detect if an object is near, impeding, or about to impede (i.e., impinging) the power beam. Each of the plurality of sensors is configured to detect the object at different distances between the transmitter and the receiver. A controller triggers the transmitter to stop generating the power beam when any one or more of the plurality of sensors detects the object or a combination of the plurality of sensors detects the object. The controller triggers the transmitter to re-generate and transmit the power beam when each of the plurality of sensors fails to detect the object.

摘要： Apparatus and associated methods relate to a photoelectric sensor system with a primary photo-detector to receive an on-axis return reflected by a retro-reflective target, and a monitor photo-detector to detect off-axis light indicative of a diffuse reflective object blocking the optical path between an emitter and the retro-reflective target. In an illustrative example, the optical path may include a coaxial transceiver module that includes a beam splitter mirror to redirect the optical path. In some embodiments, a bifurcated lens may provide, for example, a lateral offset of the emitter axis through one lens, and the return axis through an adjacent parallel lens. The second photo-detector may provide, for example, an array of one or more detection surfaces to detect off-axis light associated with a diffuse reflective object, such as a white card, for example.

摘要： Embodiments generally relate to adjusting images for an eye tracking system. In some embodiments, a method includes presenting one or more images to a user. The method further includes obtaining gaze tracking data relating to a gaze of the user with respect to the one or more images presented to the user. The method further includes detecting one or more first gaze characteristics from the gaze tracking data, wherein the one or more first gaze characteristics indicate a first state of the gaze of the user. The method further includes reducing a brightness of at least a portion of the one or more images presented to the user based on the one or more first gaze characteristics.
