Abstract: A removable facial interface for a head-mountable device (HMD) is disclosed. In an example, an HMD includes a display; a facial interface frame at least partially surrounding the display; a removable facial interface attached to the facial interface frame; a first attachment mechanism attached to one of the facial interface frame or the removable facial interface; and a second attachment mechanism attached to the other of the facial interface frame or the removable facial interface, the removable facial interface being attached to the facial interface frame by the first attachment mechanism and the second attachment mechanism.

Abstract: The present disclosure relates to systems and method for deploying a fiber optic network. Distribution devices are used to index fibers within the system to ensure that live fibers are provided at output locations throughout the system. In an example, fibers can be indexed in multiple directions within the system. In an example, fibers can be stored and deployed form storage spools.

Abstract: A user permission system manages and regulates access to secure data at one or more third-party data sites. The system may provide access to one or more databases or other data structures based on user authentication and access rules that have been established, such as by a user associated with the data being accessed at the third party data store. Access may be provided via an API to the third-party data site, along with access credentials of a user with data stored with the third-party data site, allowing the system to access data on behalf of the user.

Abstract: Access to a radio communications medium shared by at least two agents to provide peer-to-peer communication therebetween is controlled by sensing the communications medium at a first agent to determine if the communications medium is in use, transmitting from the first agent, if the first agent determines that the communications medium is not in use, a request-to-send message that includes reservation duration information, and receiving the request-to-sent message at a second agent. The second agent then transmits a clear-to-send message including reservation duration information on behalf of the first agent, after which the first agent then transmits information to the second agent while a reservation duration indicated by the reservation duration information has not elapsed. A possible third agent within receiving range of only one of the first and second agents is thereby guaranteed to receive the reservation duration information and is expected to observe the reservation according to rules disclosed.
