  • Publication number: 20200142106
    Abstract: A substrate-guided holographic diffuser has a light-guide section configured to in-couple light and transmit the light within itself via total internal reflection. It can also have a brightness enhancement section that recycles non-diffracted light within the light-guide section. A hologram section that receives light from the light-guide section has a holographic structure defining acceptance conditions and is positioned relative to the internally reflected light such that the internally reflected light meets the acceptance conditions of the holographic structure. The internally reflected light is out-coupled by the holographic structure as a projected image of light scattered from a diffuser.

  • Publication number: 20190317261
    Abstract: A holographic substrate-guided wave-based see-through display can has a microdisplay, capable of emitting light in the form of an image. The microdisplay directs its output to a holographic optical element, capable of accepting the light in the form of an image. The microdisplay directs its output to a holographic optical element, capable of accepting the image from the microdisplay, and capable of transmitting the light. The holographic optical element couples its output to an elongate substrate, capable of accepting the light from the holographic lens at a first location, and transmitting the light along a length of the substrate by total internal reflection to a second location, the elongate substrate being capable of transmitting the accepted light from the second location.

  • Patent number: 10348588
    Abstract: An illustrative embodiment of a computer-implemented process for dynamic management of integration protocols connects a set of applications to a communication fabric to form a set of connections, which are monitored to collect a set of performance metrics. In response to a determination the predetermined performance metric is not within the predetermined tolerance associated with the particular application in the set of applications an integration path in the set of connections for the particular application in the set of applications is adjusted by programmatically using a set of rules wherein each rule in the set of rules is a performance driven rule.

  • Publication number: 20170257806
    Abstract: Methods and apparatus for supporting a data center relocation with regard to an access point are described. A primary gateway connection is established between the access point and a primary gateway in a first data center, and a secondary gateway connection is established between the access point and a secondary gateway in a second data center. A path switch request is sent via the secondary gateway connection. A DNS server sends an IP address corresponding to the second data center. The data center for the access point is switched from the first data center to the second data center. In some embodiments, the transition from the first data center to the second data center is in response to a detected communications failure. In other embodiments, the transition from the first data center to the second data center is due to scheduled maintenance.
