Abstract: A display system for a head mounted device that illuminates the peripheral regions of the user's field of view to enhance an immersive experience. The system may use peripheral light emitters to the left and right of one or more central displays. Peripheral light emitters may provide lower resolution images, or only with vertical resolution, corresponding to the user's lower resolution vision in these peripheral regions. Reflective surfaces and lenses may be used to direct peripheral light into desired shapes and patterns. Rendering of peripheral light colors and intensities at each peripheral pixel may use approximations for improved performance since users may not be sensitive to precise color values in the peripheral regions.

Abstract: A system and method configured to improve the function of a network of Power Over Ethernet (POE) devices. The system and method is configured such that a digital video recorder (DVR) actively monitors the POE devices using the POE device application programming interface (API). The DVR, in response to a POE failure or non-responsive POE status may automatically power cycle the port of the network switch corresponding to the POE device, or may power cycle (reboot) the network switch. The system and method also may notify a remote user through a wide area network (WAN) and remote monitor, allowing the remote user to alternatively manually power cycle the network switch and/or the POE(s) ports.

Furthermore, naturally circulating reactor configurations are described in which the reactor cores are substantially frustum-shaped so that the thermal center of the reactor core is below the outlet of the primary heat exchangers. Heat exchanger configurations are described in which welded components are distanced from the reactor core to reduce the damage caused by neutron flux from the reactor. Radial loop reactor configurations are also described.

The server and editing clients may be collectively configured to: a) assign a feature to a first user, detect an attempt to edit the feature by a second user, and reassign the feature to the second user if the first user indicates that the feature may be reassigned, and/or b) detect an editing conflict between a first and second user for a feature and send a reversion request for the feature to one or more clients and/or c) initiate changes for a feature within a remote instance of the electronic model edited by another user and initiate reversion of the changes for the feature within a local instance of the electronic model in response to determining that the changes to the feature within the remote instance of the electronic model generated an error.

Abstract: A dynamic neutron reflector assembly for a “breed-and-burn” fast reactor incrementally adjusts neutron spectrum and reactivity in a reactor core. The composition of materials in the dynamic neutron reflector may be adjusted to change neutron reflectivity levels, or to introduce neutron moderating or absorption characteristics. The dynamic neutron reflector may contain a flowing reflecting liquid of adjustable volume and/or density. Submergible members may be selectively inserted into the flowing reflecting liquid to alter its volume and introduce other neutron modifying effects such as moderation or absorption. Selective insertion of the submergible members allows for concentration of the neutron modifying effects in a selected portion of the reactor core. The flowing reflecting liquid may also act as a secondary coolant circuit by exchanging heat with the molten fuel salt.
