Abstract: The present disclosure describes methods, devices, and non-transitory computer readable storage medium for managing lifecycle of a knowledge base (KB) in chatbot systems. The method includes receiving an update request and updating a current-version KB as a new current-version KB. The method also includes receiving a first test request from a knowledge point (KP) operator and determining whether the new current-version KB passes a first test; and in response to the determination that the new current-version KB passes the first test, submitting the new current-version KB as a new submit-version KB. The method further includes receiving a second test request from a KP manager and determining whether the new submit-version KB passes a second test; and in response to the determination that the new submit-version KB passes the second test, storing an original production-version KB as a pervious-version KB and submitting the new submit-version KB as a new production-version KB.

Abstract: Provided is a method for determining a Hybrid Automatic Repeat Request (HARQ) transmission signal. The method comprises receiving soft bits from a wireless communication physical channel uplink signal, said received soft bits being deemed to comprise HARQ LLRs and soft decoding said HARQ LLRs to output a hard ACK/NACK decision. The method includes processing said HARQ LLRs based on said hard ACK/NACK decision such that the processed HARQ LLRs map to a same or identical constellation point or points if the physical channel uplink signal contains an ACK or NACK transmission signal. The method also includes using said processed HARQ LLRs to determine if the physical channel uplink signal contains an ACK or NACK transmission signal or to determine if the physical channel uplink signal comprises discontinuous transmission (DTX).

Abstract: Optical inspection system detects defects of an object, such as an electronic device during manufacturing. The optical inspection system includes a first linear light source that irradiates a first light beam on a top surface of the object along a scan line across the width of the object. A second linear light source forms an angle with the first linear light source and irradiates a second light beam on a side surface of the object. A camera receives scattered light from the top surface and the side surface of the object and captures a subimage of the object along the scan line. An image processing system receives each subimage from the camera, stitches the subimages, and detects defects on the top surface and the side surface of the object.

Abstract: Systems and methods providing low-density parity-check (LDPC) decoder configurations capable of decoding multiple code blocks in parallel are described. Parallel LDPC decoders of embodiments can be reconfigured to simultaneously decode multiple codewords with reconfigurable size. In operation of embodiments of a parallel LDPC decoder, a plurality of active portions of the decoder logic are configured for parallel processing of a plurality of code blocks, wherein each active region processes a respective code block. The decoder logic active portions of embodiments are provided using a reconfigurable segmented scalable cyclic shifter supporting multiple instruction, multiple data (MIMD), wherein multiple individual different data shifts are implemented with respect to a plurality of code blocks in an instance of data shifting operation. Multiple data shift commands may be utilized such that the plurality of code blocks have an individual shifting command to thereby implement different data shifting with respect to each code block.

Abstract: Systems and methods providing synchronization of wireless device data based upon device synchronization prioritization determinations are described. Embodiments may make device synchronization prioritization determinations using device grouping identifiers with respect to a plurality of wireless devices and/or one or more device synchronization parameters for the wireless devices. Logic of a synchronization prioritization gateway of embodiments may implement a prioritization determination algorithm to determine a sequence of wireless devices for data synchronization for facilitating data synchronization with respect to a plurality of wireless devices in a timely and efficient manner. The logic of the synchronization prioritization gateway may implement a priority penalty attribute with respect to particular wireless devices to address aberrant behavior or other operation likely to impede efficient and/or timely data synchronization.

Abstract: Systems and methods which provide a compact spectrometer using static Fourier transform interferometer (SFTI) cube configurations, such as are suitable for use with respect to mobile and portable electronic devices, are described. A SFTI cube of embodiments comprises a monolithic dual mirrored wedge beam splitter structure wherein mirrored wedge surfaces provide two reflective mirrors that are slightly tilted away from the orthogonal directions so that the resultant beams of light cross over one another and form an interference pattern. SFTI cube implementations of embodiments facilitate highly compact spectrometer configurations having a wide wavelength range, high resolution, high throughput, and low cost.

Abstract: Methods and systems which provide object edge image representation generation using block based edgel techniques implementing post edgel detection processing to eliminate false edges are described. Embodiments subdivide image data (e.g., image point clouds) to facilitate separate edgel detection processing of a plurality of sub-blocks of the image data. A false edge elimination algorithm of embodiments is applied in recombining the object edge image representation sub-blocks resulting from the sub-block edgel detection processing to eliminate false edge artifacts associated with use of block based edgel detection.

Abstract: The present disclosure relates to methods and systems for generation of a beacon identifier (ID) for increased security of a system for a location based service. The system includes a beacon device, such as a BLE device, a mobile device, and a server. The beacon device is configured to generate a beacon ID based on a beacon device identifier, such as a unique device identifier, of a beacon device and a time value. In some implementations, generation of the beacon ID includes a pseudorandom function and a shared key that is established between the beacon device and the server.

Abstract: Methods are described for detecting an edge of an object within an image with a fractional differential operator. Methods are also described for calculating 3D information using a strip pattern and the disclosed edge detection method. The fractional differential operator may be a modified Riesz space fractional differential operator. When calculating the fractional derivative of the image, a kernel approximation, in which a scaled Gaussian kernel function or a simplified scaled Gaussian kernel function, is applied to discretize the modified Riesz space fractional differential operator locally. The disclosed method improves the accuracy of edge detection, eliminates the need of applying additional fractional integration for noise suppression, and requires a smaller mask length to achieve desired accuracy.
