Abstract: Method of analysis text message syntactically and by content, which entails: step 1; Split syntaxes (made available to subscribers by the network operator) into tokens to store in a Syntax Trie; step 2. Pre-process an incoming text from a subscriber; step 3. Split the text (pre-processed in Step 2) into tokens; step 4. Look up paths that include the tokens (obtained in Step 3) in the Syntax Trie (initialized in Step 1); step 5: Return the look-up result, which is the path in the Syntax Trie that best reflects the user intent.

Abstract: A control system for a voice assistant system for implementing actions associated with a vehicle includes one or more controllers and an interface configured to receive a request from the voice assistant system. The request indicates a task requested by a user of the voice assistant system. Processing means arranged to execute, in dependence on the request, a task handler corresponding to the task. The task handler is arranged to cause the control system to perform a plurality of actions associated with the task, to generate a response in dependence on an output of at least some of the plurality of actions and to output the response via the interface to the voice assistant system.

Abstract: The present disclosure generally relate to spin-orbit torque (SOT) devices. The SOT devices each comprise a non-magnetic layer, a free layer disposed in contact with the non-magnetic layer, and a bismuth antimony (BiSb) layer disposed over the free layer. The non-magnetic layer has a thickness of about 0.5 nm to about 2 nm. The BiSb layer has a thickness of about 5 nm to about 10 nm. The BiSb layer and the free layer have collective thickness between about 5 nm to about 20 nm. By reducing the thickness of the non-magnetic layer and BiSb layer, a read gap of each SOT device is reduced while enabling large inverse spin Hall angles and high signal-to-noise ratios.

Abstract: A smart landing pad comprises a flexible display that shows images or patterns, and a protective layer over the display. The protective layer allows a UAV to land without damaging the display. Locator and range finder devices, coupled to the display, communicate with the UAV. The display is operative for wireless communications with a computer or mobile device that provides on-demand user functions, allowing for dynamically changing or customizing the images/patterns shown on the display. The images/patterns comprise a background area showing changeable images that match an environment where the landing pad is placed, and a target landing area surrounded by the background area. The target landing area includes a changeable insensitive, contrast portion, and changeable marker pattern portions having changeable colors/shapes. The images/patterns also include changeable QR codes on the target landing area. The display is IoT enabled so that data from the landing pad is remotely cloud accessible.

The half Heusler alloy-topological semi-metal supplies a spin current to the ferromagnet based on a current flowing in a direction parallel to a first surface that is in contact with the ferromagnet.

Abstract: Methods for distributed histogram computation in a framework utilizing data stream sketches and samples are performed by systems and devices. Distributions of large data sets are scanned once and processed by a computing pool, without sorting, to generate local sketches and value samples of each distribution. The local sketches and samples are utilized to construct local histograms on which cardinality estimates are obtained for query plan generation of distributed queries against distributions. Local statistics of distributions are also merged and consolidated to construct a global histogram representative of the entire data set. The global histogram is utilized to determine a cardinality estimation for query plan generation of incoming queries against the entire data set. The addition of new data to a data set or distribution involves a scan of the new data from which new statistics are generated and then merged with existing statistics for a new global histogram.
