Abstract: The present concepts relate to lossless data compression techniques for reducing the size of a data structure. Certain data in the data structure that can be either recovered from another source or rebuilt from other available information may be removed from the data structure. To further reduce data size, the retained data in the data structure may be packed into a smaller-bit encoding data type. Additionally, to reduce the data size even more, the packed data may be zipped using a lossless data compression algorithm. To regain the original data structure, the process may be reversed. The zipped data may be unzipped using a lossless data decompression algorithm. The packed data may be unpacked into the original bit-sized data encoding. The removed data may be restored by either recovering it from another source or rebuilding it from other available information.

Abstract: A hinged mobile computing device includes a first housing part with a first display and a second housing part with a second display. The first and second housing parts are coupled by a hinge assembly that includes a spring-loaded opening mechanism configured to bias with a biasing torque the first housing part and second housing part to rotate away from each other when the first and second displays are in a closed face-to-face orientation. An electro-magnetic closure system is configured to retain the first and second displays in the closed face-to-face orientation against the biasing torque of the spring-loaded opening mechanism, and release of the electro-magnetic closure system permits the first housing part to rotationally separate from the second housing part to a predetermined angular orientation due to the biasing force of the spring-loaded opening mechanism.

Abstract: Aspects of the present disclosure relate to semantic user input for a computing device. In examples, user input is identified and processed to identify and automatically perform an associated semantic action. The semantic action may be determined based at least in part on an environmental context associated with the user input. Thus, an action determined for a given user input may change according to the environmental context in which the input was received. For example, an association between user input, an environmental context, and an action may be used to affect the behavior of a computing device as a result of identifying the user input in a scenario that has the environmental context. Such associations may be dynamically determined as a result of user interactions associated with manually provided input, for example to create, update, and/or remove semantic actions associated with a variety of user inputs.

Abstract: Innovations in syntax and semantics of coded picture buffer removal delay (“CPBRD”) values potentially simplify splicing operations. For example, a video encoder sets a CPBRD value for a current picture that indicates an increment value relative to a nominal coded picture buffer removal time of a preceding picture in decoding order, regardless of whether the preceding picture has a buffering period SEI message. The encoder can signal the CPBRD value according to a single-value approach in which a flag indicates how to interpret the CPBRD value, according to a two-value approach in which another CPBRD value (having a different interpretation) is also signaled, or according to a two-value approach that uses a flag and a delta value. A corresponding video decoder receives and parses the CPBRD value for the current picture. A splicing tool can perform simple concatenation operations to splice bitstreams using the CPBRD value for the current picture.

Abstract: To meet the stringent requirements on simulating motion of an object, a body state of the object needs to be processed in real time while minimizing an error of deviating from the trajectory and time as specified, using limited computing resources. The present disclosure simulates physical aspects of an object in motion by generating a rigid body model that includes external force data and data representing the object.

The disclosed technology uses non-linear inversion dynamics controllers to compute the body forces for following a prescribed trajectory and a rigid body model solver with advanced integration techniques providing low-latency, accuracy, and integrity of linear and rotational body states.
