摘要： Systems and methods for creating and operating separate secure networks over a non-secure network are described herein. Some illustrative embodiments include a system that includes a router with one or more ports and control logic coupled to the one or more ports (the control logic capable of establishing a plurality of secure data paths with at least one other router across a network), and a plurality of external storage devices (each storage device separate from the router but capable of being detachably coupled to a port of the one or more ports, and each external storage device comprising configuration data defining one or more secure data paths of the plurality of secure data paths). Configuration data stored in a first external storage device of the plurality of external storage devices is different from configuration data stored in a second external storage device of the plurality of external storage devices.

摘要： Systems and methods for managing router configuration devices in a secure data communication network are described herein. An illustrative system includes a plurality of programmed external configuration devices and a configuration device programmer. Each programmed external configuration device contains at least a portion of a definition of a secure data path between a first router and a second router. Each programmed external configuration device can be detachably coupled to a first router to create a secure data path between the first router and a second router. The configuration device programmer writes a secure data path definition into a selected external configuration device if a predetermined number of programmed external configuration devices are coupled to the configuration device programmer.

摘要： Screen apparatuses are provided which include a first lens or holographic optical element layer and a second mask layer. The first layer substantially collimates image light rays to impinge on the mask layer. The mask layer provides an array or matrix of projecting members. Each of the projecting members receives and focuses the substantially collimated light rays to corresponding focal points. The mask layer includes a mask that blocks light transmission except where openings are located. The openings allow the light focused through the focal joints to substantially pass through the mask to form an image. The screen apparatuses can be advantageously employed in display apparatuses.

摘要： In a color sequential system using LCDs, the LCD must operate faster than the frame rate because red, green, and blue are done sequentially. Ferroelectric LCDs can do this, but they are not analog devices and so cannot provide analog display levels. Instead, a pulse width modulation (PWM) technique is used. In the system of the present invention, each pixel has three storage devices to hold RGB analog levels. A latch is used to load these values in parallel. Then an analog 3:1 multiplexer is used to select the proper storage device for the current sequential color. The multiplexer output goes to a comparator, which has a sawtooth waveform input at much faster than the frame rate. The comparator output changes with the sawtooth level, so that PWM control is provided for each pixel. As an alternative, standard analog LCD pixels can be sequentially switched between three color input storage devices.

摘要： Systems for safeguarding router configuration data are described herein. Some illustrative embodiments include a system that includes a network router, a configuration device comprising configuration data used to configure the network router, and a connector capable of detachably coupling the configuration device to the network router and further capable of detachably coupling a second device to the network router (the connector routes electrical power provided by the network router to a coupled device). The electrical power is set to a voltage level usable to operate the configuration device, while capable of rendering the second device inoperative.

摘要： A screen apparatus includes a holographic optical element and a diffuser. The holographic optical element may be constructed using standard techniques known in the field of holography. The holographic optical element may be used to replace a typical Fresnel lens used in projection screen apparatuses. In operation, the holographic optical element receives image light from an image engine or projector and redirects the image light to the diffuser for scattering. The holographic optical element can be designed to substantially collimate, converge, or diverge the image light. The combination of the holographic optical element and the diffuser provides improved illumination uniformity that can be perceived by a viewer as the viewer moves in directions transverse to the screen apparatus. The screen apparatus may be designed to provide improved illumination uniformity to optimized or optimal locations in a viewing region. The screen apparatus may be advantageously employed in display apparatuses.

摘要： Light sources include an electrodeless bulb having an interior, a fill contained within the interior of the bulb, an excitation structure that transmits electromagnetic energy to the fill in the bulb, and cooling fins extending radically outward from the bulb. The fill is excited by the electromagnetic energy to a plasma state that causes light emission and generates heat energy. The cooling fins, when rotated, draw air toward the bulb to cool the bulb. Alternatively, cooling may be provided by a rotatable squirrel cage about an electrodeless bulb. The light sources can be used in display systems, such as field sequential color systems.
