    Abstract: A decoding device includes storage to store image data including grayscale values of pixels in multiple captured images, and a processor including multiple SIMD components and at least one component. For each captured image at least one available SIMD component performs: at least one transform with the grayscale values of at least one portion of the captured image to generate at least one corresponding metadata; and the at least one transform in preparation for an analysis of the at least one metadata by the at least one core component. The at least one core component is to perform: the analysis to identify at least one ROI within the captured image indicated by the at least one metadata to include at least one encoded data marking; and a decoding of the at least one ROI to attempt a decode of the at least one encoded data marking.

    Abstract: 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.

    Abstract: Systems and methods of operation for a machine-readable symbol reader for estimating the distance of a scanned target object or item labeled with indicia, such as a machine-readable symbol. The reader may include an illumination subsystem which projects a light pattern (e.g., line) out from the reader. The reader may capture an image of the target object while the light pattern is projected thereon and analyze at least one detectable characteristic of the pattern to estimate distance of the target object relative to the reader. A one-dimensional sensor array of the reader may be exploited in part for imaging a symbol and in part for imaging detectable characteristics (e.g., edges) of the projected illumination pattern which allows for estimation of the reading distance. A central portion of the one-dimensional sensor array may be dedicated to imaging a machine-readable symbol and lateral portions may be dedicated to implementing a range finder.

    Abstract: A system and method for an active Q-switched fiber laser cavity may include a pump source for emitting a laser beam at a wavelength along an optical path including an active optical medium. A modulation device may be configured to introduce tunable losses into the optical path. The tunable losses may be achieved through modulation of the transmissivity of an optical element within the optical path, the modulation of said optical element being performed over (i) a first period of time in which a cavity Q curve increases from a first percentage value to a second percentage value of a maximum Q value and (ii) a second period of time in which the cavity Q curve increases from a third percentage value to a fourth percentage value of the maximum Q value. The cavity Q curve may non-linearly and smoothly transition between (i) the first and second percentage values and (ii) the third and fourth percentage values.

    Abstract: Systems and methods which utilize wireless charging to initiate near field communication (NFC) pairing between mobile systems which utilize wireless charging and wireless charging base stations. Wireless signals sent by a mobile system over a wireless charging channel are used to initiate communication between an NFC reader presented in a base station and a passive NFC tag (or an active NFC tag used in a passive mode) present in the mobile system. Such feature allows the mobile system to act as an initiator for NFC communication without requiring the mobile system to be equipped with an NFC reader. A wireless power receiver of a mobile system may communicate with a wireless power transmitter of a base station using backscatter modulation. Commands of a standard wireless charging protocol may be repurposed to send a request for initiation of an NFC session from a mobile system to a base station.

    Abstract: The present invention relates to a method for receiving a pulsed signal emitted by an emitter (2,20) in an optoelectronic sensor (1), the sensor including at least an emitter (2,20) for emitting electromagnetic radiation and a receiver (3, 30) for receiving electromagnetic radiation and wherein the electromagnetic radiation received is converted into an electric signal, said method including the steps of: o arranging said emitter to emit a pulsed electromagnetic radiation; o before the emission of a pulse, receiving an electromagnetic radiation received through said receiver (3, 30) by generating a noise signal (sr,S1,S2); o comparing an amplitude of said received noise signal (sr,S1) with a first threshold (Vthreshold); and o emitting said pulse if the amplitude of said received noise signal is below said first threshold, and not emitting said pulse otherwise. The invention also relates to an optoelectronic sensor.

    Abstract: Systems, methods, and computer-readable storage media are provided for identifying (recognizing) an object from its shape in a sequence of images utilizing sequence alignment matrices (SAMs). For a given image, an object is segmented and from the segmented object, a set of key points is extracted. From the extracted key points, a set of local feature descriptors, strictly related to the key points and uniquely ordered in sequence, are extracted. The feature sequence obtained from the segmented object is aligned with a counterpart or reference image (e.g., a model or another image) using a Sequence Alignment Matrix (SAM). A custom scoring technique for the alignment provides a quality index for the identification of the object.
