摘要： 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.

摘要： An optical symbol reading system comprises an image sensor operative to capture an image of a target area, a color-sensing system sensitive to certain colors in the visible spectrum, an illumination system operative to produce various types of illumination based on illumination parameters, and a surface-profiling system arranged to measure distance to multiple points of at least one surface in the target area. The illumination system, the image sensor, and the color-sensing system are arranged such that emitted light from the illumination system, in accordance with a selected type of illumination, is directed towards the target area while a portion of the emitted light is reflected from any object of interest present in the target area and received by the image sensor and the color-sensing system. The type of illumination is selected based on output from the color-sensing system and the surface-profiling system.

摘要： An object detector reads distance measurement information and determines any presence of at least a portion of an object within a target area between the object detector and a background surface. The determination of the presence is based on distance measurement information. The distance measurement information is compared against a lower distance threshold and an upper distance threshold, where the lower distance threshold represents a distance between the object detector and the background surface, less a subtracted margin; and the upper distance threshold representing a distance between the object detector and a point beyond a distance of the background surface by an added margin. Satisfaction of either distance threshold is indicative of the presence of at least a portion of the object within the target area.

摘要： An imaging device has a focusing device flanked by electromagnets such that a magnetic levitation between the electromagnets and permanent magnets in the focusing device cause the focusing device to rotate about an axis. This rotation causes the optical axis of the focusing device to read an extended reading field beyond the ordinary reading field when the focusing device is in a balanced magnetic levitation position.

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 present disclosure relates to data readers including an improved imaging system 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 based on a measurement reading by a rangefinder and acquire an image of an item in the field-of-view of the data reader. The data reader includes a decoding engine 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 and reattempt the decoding process.

摘要： A wireless power system and method performs wireless power transmission with sensing to detect a distance and/or misalignment of a power receiver from the power transmitter. Power transmission is adjusted in response to the sensing detecting the distance and/or misalignment exceeding a determined threshold, or in response to instructions sent by the receiver based, at least in part, on a duration of the overvoltage condition exceeding a determined time period.

摘要： A time of flight sensor system having a time of flight sensor layer is disclosed. The system includes a covering window layer spaced apart from the time of flight sensor layer, with an exit window and an entrance window, an emitting element in the time of flight sensor layer that transmits an emission signal, a receiving element in the time of flight sensor layer that receives a reception signal, one or more opaque walls, and light baffles incorporated into the one or more opaque walls. The one or more opaque walls extend at least a portion of the distance from the time of flight sensor layer to the covering window layer. The one or more opaque walls reduce the reflection backscatter of emission signals and reception signals. The light baffles in the one or more opaque walls reduce backscatter of emission signals and reception signals.
