  • Patent number: 9656162
    Abstract: A system recognizes human beings in their natural environment, without special sensing devices attached to the subjects, uniquely identifies them and tracks them in three dimensional space. The resulting representation is presented directly to applications as a multi-point skeletal model delivered in real-time. The device efficiently tracks humans and their natural movements by understanding the natural mechanics and capabilities of the human muscular-skeletal system. The device also uniquely recognizes individuals in order to allow multiple people to interact with the system via natural movements of their limbs and body as well as voice commands/responses.

  • Publication number: 20170130089
    Abstract: A method of improving the adhesion of metathesis compositions, such as ring-opening metathesis polymerization (ROMP) compositions, to a substrate is disclosed, in which an adhesion promoter is added to a polymerizable resin composition in order to improve the adhesion of the polymerizing resin to a substrate material. The addition of the adhesion promoter has been found to provide beneficial improvements in the adhesion of metathesis, especially ROMP, compositions to substrates, particularly glass surfaces, leading to improved characteristics in ROMP materials formed therefrom. The adhesion promoter generally comprises a functionalized silane compound and a peroxide compound. A ROMP composition is further disclosed comprising a cyclic olefin, a ROMP metathesis catalyst, and the adhesion promoter. Polymer products produced via metathesis (ROMP) reactions of the invention may be utilized to provide a wide range of materials and in a variety of composite applications.

  • Patent number: 9419794
    Abstract: An SOC implements a security enclave processor (SEP). The SEP may include a processor and one or more security peripherals. The SEP may be isolated from the rest of the SOC (e.g. one or more central processing units (CPUs) in the SOC, or application processors (APs) in the SOC). Access to the SEP may be strictly controlled by hardware. For example, a mechanism in which the CPUs/APs can only access a mailbox location in the SEP is described. The CPU/AP may write a message to the mailbox, which the SEP may read and respond to. The SEP may include one or more of the following in some embodiments: secure key management using wrapping keys, SEP control of boot and/or power management, and separate trust zones in memory.

  • Publication number: 20160034025
    Abstract: An integrated circuit (IC) implements an industry standard-defined peripheral interconnect to connect to another integrated circuit or component in a system. The industry standard specification includes a software interface that is well-defined and implemented by various software in the system, and thus is desirable to retain. However, the physical interconnect in the systems employing the integrated circuit may be short, and thus the elaborate physical layer definition may consume more integrated circuit area and power than is otherwise desirable in the IC. The IC may implement a simpler and more power-efficient physical layer, reducing both power consumption and semiconductor substrate area consumption, in some embodiments.

  • Publication number: 20150165652
    Abstract: Articles of manufacture possessing corrosion resistance characteristics are described, in particular for use in the chlor-alkali and other industries. The articles are formed from a resin composition, e.g., a cyclic olefin composition, polymerized with a Group 8 olefin metathesis catalyst. In particular aspects, an electrolytic cell component, such as a cell cover for use in the electrolysis of brine, may be formed from the resin composition. Among other benefits, such articles provide improved corrosion resistance compared to articles molded from other resin compositions, such as Fiberglass reinforced polyesters and vinyl esters, and two-component dicyclopentadiene (DCPD) resins comprising molybdenum or tungsten pre-catalysts.
