A self-contained interactive video display system. A flat-panel display screen displays a visual image for presentation to a user on a front side of the flat-panel display screen. A first illuminator illuminates the flat-panel display screen with visible light. A second illuminator illuminates an object. A camera detects interaction of an illuminated object with the visual image, wherein the camera is operable to view the object through the flat-panel display screen. A computer system directs the projector to change the visual image in response to the interaction.

A system for imposing a filter between a vehicle driver's eyes and a source of light including at least one detector facing inward into a compartment in the vehicle toward a likely position of the head of the vehicle driver and arranged to obtain images of the eyes of the driver and a processor coupled to the detector(s) and arranged to determine the location of the driver's eyes based on analysis of the images obtained by the detector(s) and to obtain information about objects exterior of the vehicle providing sources of light from the images obtained by the detector(s) based on reflections off of the driver's eyes, i.e., the position of such objects. A filter, such as a pixelated screen, is imposed between the sources of light and the driver's eyes based on the location of the driver's eyes and the information about the exterior objects providing the sources of light.

A LCD display system comprises a LC panel (1), a backlight unit (2) for illuminating the LC panel (1) or a portion thereof, and a controller (3). The controller: (i) controls the LC panel (1) to display a first image (LI) and a second image (RI) forming a stereoscopic pair, (ii) controls the backlight unit (2) to only illuminate the LC panel (1) or the portion thereof during a first period in time (BLON1; T1) after the pixels (10) of the LC panel (1) or the portion thereof have a stable optical state according to the first image (LI), and during a second period in time (BLON2; T2) after the pixels (10) of the LC panel (1) or the portion thereof have a stable optical state according to the second image (RI), and (iii) generates a control signal (CSS) for controlling a first one (40) of a pair of 3D shutter glasses (4) to be in a transmissive state for enabling viewing of the pixels (10) of the LC panel (1) or the portion thereof only during the first period in time (BLON1; T1) and a second one (41) of the pair of 3D shutter glasses (4) to be in a transmissive state for enabling viewing of the pixels (10) of the LC panel (1) or the portion thereof only during the second period in time (BLON2; T2).

A mechanical-to-acoustical transducer has at least one actuator, preferably a piezo motor, that is coupled, generally perpendicularly, to one edge of a diaphragm formed from a thin, flexible sheet material. The diaphragm is fixed at a point spaced from the actuator in the direction of its motion so that excursion of the actuator is translated into a corresponding, mechanically-amplified, excursion of the diaphragm—typically amplified five to seven times. The diaphragm is curved, preferably parabolically, and to a small degree. The diaphragm, if optically clear, can be mounted on a frame over a video display screen to provide a screen speaker. Preferably, such a screen speaker is pinned or adhered at upper and lower edges at or near its vertical centerline and is supported by and driven at both lateral edges by one or more single layer piezo actuators. The actuators are secured at one end to the frame or other stationary member, and at a free, movable end, to an edge of the diaphragm, generally at right angles. A gasket seals the edges of the diaphragm to maintain an acoustic pressure gradient across the diaphragm.
