    Abstract: Techniques and architecture for determining compliance of a network with respect to a network design solution. The techniques may include determining a role for each network device of a network that comprises multiple network devices and determining one or more policies related to each network device with respect to other network devices of the network. The techniques may further include based at least in part on the roles for each network device and the one or more policies, determining a level of compliance of a configuration of the network with respect to a network design solution. Based at least in part on the level of compliance, a remedial action may be performed. In configurations, a machine learning model may be used.

  • Patent number: 11436806
    Abstract: Systems and methods are described to render a Live Avatar View third-person view as an overlay of a first person Spectator View, as mirrored from a Virtual Reality headset, in a Dual Perspective View. In some embodiments, a clinician tablet may display Dual Perspective View with a full screen Spectator View, to maximize visibility, and render a translucent avatar from Live Avatar View (LAV) to overlay the Spectator View for simultaneous visibility during a therapy session. Spectator View may be critical to monitor for therapy guidance and an LAV conveys valuable movement and safety data. A translucent avatar overlay and activity cues allows monitoring the avatar from Live Avatar View in a way that would not block the Spectator View or occlude other body parts potentially hidden.

  • Patent number: 11065205
    Abstract: In one aspect, the present invention is concerned with a treatment where it is desired that an active agent is designed to be released immediately following administration and again at a time point some time after administration of the active agent. The present invention is particularly suited to administering an agent which may be released before sleep and whilst a subject is sleeping. As well as treating certain conditions by a particular regime, the invention also provides novel formulations for an immediate, followed by a delayed release of drug.

  • Patent number: 10913659
    Abstract: A novel synthetic crystalline aluminogermanosilicate molecular sieve material, designated SSZ-114, is provided. SSZ-114 can be synthesized by treating an aluminogermanosilicate molecular sieve of CTH framework topology with water or an aqueous solution of a mineral acid under conditions sufficient to degermanate at least a portion of aluminogermanosilicate molecular sieve to form a degermanated molecular sieve and calcining the degermanated molecular sieve under conditions sufficient to convert the degermanated molecular sieve to SSZ-114. Molecular sieve SSZ-114 may be used in organic compound conversion reactions and/or sorptive processes.

  • Patent number: 10010877
    Abstract: A process has been developed for preparing a Fischer-Tropsch catalyst precursor and a Fischer-Tropsch catalyst made from the precursor. The process includes preparing a catalyst precursor by contacting a boehmite material with a stabilizer containing vanadium-phosphorus. The boehmite material includes two or more different crystalline boehmites having the same average crystallite size to the nearest whole nanometer and having differing properties selected from surface area, pore volume, density and combinations thereof. The boehmite material is subjected to at least one heat treatment at a temperature of at least 500° C., either before or after the contacting step to obtain a stabilized catalyst support having a pore volume of at least 0.3 cc/g. A catalytic metal or a compound containing cobalt is applied to the stabilized catalyst support to form the catalyst precursor. Finally, the catalyst precursor is reduced to activate the catalyst precursor to obtain the Fischer Tropsch catalyst.
