Abstract: In a display assistant device, a speaker is mounted in a waveguide structure which is at least partially disposed beneath a display screen. The waveguide structure is mounted in an exterior housing which includes speaker grills distributed on a plurality of surfaces of the exterior housing, permitting sound waves from the speaker to be projected outside the exterior housing. A cover structure is disposed on top of the waveguide structure to conceal the waveguide structure and speaker within the exterior housing. The cover structure has a tilted bottom surface configured to be suspended above the waveguide structure and to be separated by a first space. Sound waves projected from an upper portion of the speaker are reflected by the tilted bottom surface and are guided through the first space to exit the device from a speaker grill portion located on a rear side of the exterior housing.

Abstract: The concepts, systems and methods described herein are directed towards a security system. The system is provided to include a Hardware Root of Trust (HRoT) device comprising a processor and memory that is configured for connection and authentication to first and second host devices which are configured to communicate via a first communication channel having a first security level and a second communication channel having a second security level which is more secure than the first security level. The HRoT device is configured to: connect the first and second host devices via the second communication channel; and monitor the security of the first and second host devices over the second communication channel.

Abstract: A trusted network access control system has a remote computing platform running an advisor. A first trusted network access control device is coupled to the remote computer by a network. A director is coupled to the first trusted network access control device and controls the first trusted network access control device.

Abstract: Bowstrings are constructed of braided strands, preferably comprising flat braids, from a high strength mixture of yarns comprising abrasion-resistant fibers and yarns comprising high strength, creep resistant fibers.
