    Abstract: A lens antenna system is disclosed. The lens antenna system comprises a hybrid focal source antenna circuit configured to generate a source antenna beam for integration with different lens structures. In some embodiments, the hybrid focal source antenna circuit comprises a set of antenna elements coupled to one another. In some embodiments, the set of antenna elements comprises a first antenna element configured to be excited in a first spherical mode; and a second antenna element configured to be excited in a second, different, spherical mode. In some embodiments, the first spherical mode and the second spherical mode are co-polarized. In some embodiments, the lens antenna system further comprises a lens configured to shape the source antenna beam associated with the hybrid focal source antenna circuit, in order to provide an output antenna beam.

    Abstract: Apparatus, method and storage medium associated with UAV position estimation are disclosed herein. In embodiments, an UAV may comprise a transmitter-receiver arrangement to transmit and receive communication signals, including receipt of absolute positioning system (APS) signals from one or more APS sensors, and wireless signals from one or more proximately located other UAVs; one or more motors or engines to provide propulsive force for the UAV; and a flight controller coupled to the transmitter-receiver arrangement and the one or more motors or engines to control at least the one or more motors or engines to provide propulsive force to navigate the UAV, based at least in part on the APS and relative positioning signals. Other embodiments may be disclosed or claimed.

    Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to map a virtual environment to a physical environment using a weighted linear mapping technique. Example methods disclosed herein include accessing dimensional data corresponding to the virtual environment. Disclosed example methods further include determining areas of relative importance in the virtual environment. Disclosed example methods also include accessing dimensional data corresponding to the physical environment and generating a mapped environment based on the dimensional data corresponding to the virtual environment, the dimensional data corresponding to the physical environment, and the areas of relative importance.

    Abstract: Techniques are provided for the scheduling of file pre-fetches from a file system into a cache memory, to reduce subsequent latency associated with future accesses to those files. A methodology implementing the techniques according to an embodiment includes monitoring accesses to files of the file system (e.g., file open and file read operations) and maintaining a record for each of the accessed files. The record includes an identifier of the file, the number of accesses of the file, and the number of cache memory misses associated with those accesses. The method also includes storing the record into a file access history database (FAHD). The method further includes generating, in response to an Operating System (OS) shutdown, a frequently used file list (FUFL) based on the FAHD. The method further includes pre-fetching files identified by a selected subset of the FUFL to the cache memory during an OS boot.

    Abstract: Systems, apparatuses and methods may provide for compressed virtual memory (CVM) management using CVM arbitration. CVM arbitration may monitor CVM utilization, tune CVM and update CVM settings that may be enabled upon reboot of a system and/or apparatus. The CVM arbitration may improve memory management, thereby improving system performance and user experience.

    Abstract: Systems, apparatuses and methods may provide technology for managing a runtime computing environment having tiered object memory placement that assigns a hotness score to an object having an object type based on an invocation count of objects referenced by a hot method, allocates a newly-created object to one of a hot object heap, said hot object heap assigned to store hot objects in a first memory tier, or a cold object heap, said cold object heap assigned to store cold objects in a second memory tier, based on the hotness score associated with the object type for the newly-created object, and migrates a plurality of objects between the hot object heap and the cold object heap based on a hotness score associated with each object. The technology may also operate the object migration in an execution thread independent of an execution thread for the object allocation.
