An audio processing system for a vehicle includes a plurality of loudspeakers positioned to form a single line array. The loudspeaker line array is positionable in a vehicle on a dashboard of the vehicle substantially at the convergence of the dashboard and a window of the vehicle. When the loudspeaker line array is driven by an audio signal, a vertically and horizontally focused and narrowed sound pattern is perceived by a listener in the vehicle. The sound pattern is the result of the constructive combination of the direct sound impulses and the reflected sound impulses produced by each loudspeaker in the array. Using delay, attenuation and phase adjustment of the audio signal, the sound pattern may be controlled, limited, and directed to one or more locations in the vehicle.

An active pixel masking system for automatic glare suppression uses a variably transmissive screen such as an LCD in front of a lens. A measurement by an image sensor of oversaturated pixels from one or more extremely bright lights is used to generate corresponding opaque pixels in the variably transmissive screen, thereby preventing the excess light from entering the lens, and thereby clarifying the appearance of any objects near to the bright light. A continuous reading of a motion picture image is used to move the location and area of the opaque pixels in response to the motion and area of the light.

An election system provides, in one example, each voter with multiple physical “layers” that the voter is able to choose between. The voter takes part of the layers as a kind of receipt and the other layers are retained and / or destroyed by the system. The actual vote is not readily revealed by the layers taken by the voter, thus protecting against improper influence. In the voting booth, when all the layers are combined, however, the voter is readily able to verify the vote. Moreover, posted images of the layers not taken by the voter can be used to compute the election results in a way that is verifiable by interested parties. The results cannot be changed without substantial probability of detection and privacy of votes can be maintained unless a number of parties are compromised or collude.

An x-ray tube is described that includes components for increasing x-ray image clarity in the presence of a moving x-ray source by modifying focal spot characteristics, including focal spot size and focal spot position. In a first arrangement a static focal spot is moved in a direction contrary to the movement of the x-ray source so that an effective focal spot position is essentially fixed in space relative to one of the imaged object and / or detector during a tomosynthesis exposure. In a second arrangement, the size of the static focal spot is increased, and the resulting increase in tube current reduces the exposure time and concomitant blur effect. The methods may be used alone or in combination; for example an x-ray tube with a larger, moveable static focal spot will result in a system that fully utilizes the x-ray tube generator, provides a high quality image with reduced blur and, due to the decrease in exposure time, may scan the patient more quickly.
