Title: Head-mounted single-panel stereoscopic display
Inventor: ROBINSON MICHAEL G
IPC: G02B30/25
Filed: 2008-07-25
Abstract: Disclosed is a head-mounted single panel display system that uses one or more liquid crystal switches and a polarizing beam splitter to redirect images from a single microdisplay panel to the viewer's eyes. The light emanating from the display panel is first directed, using a polarizing beam splitter, into two near-identical optical imaging systems, each forming an image in the left and right eyes. For stereoscopic (3D) operation, the light is modulated such that an image is seen in only one eye at a time. By providing time sequential stereoscopic imagery at a frame rate greater than 50Hz in each eye, flicker free, full resolution 3D can be visualized.

Abstract: PURPOSE: A multi functional damper for ventilation and a firefighting is provided to control the flow of ash or smoke into a room without power, and to ventilate the room through an air path at other times. CONSTITUTION: A multi functional damper for ventilation and a firefighting comprises a base plate(206), a base panel(207), a rotary gear(208), an idle gear(211), a power breaker, a rod, and a smoke detector(216). The rotary gear is connected to one end of a rotary shaft(201), and installed along the base plate. The idle gear transfers rotary force to a driving motor(204), and spring elasticity is applied. The idle gear is engaged with a spring(209). The power breaker transfers the rotary force of a motor gear connected to the shaft of the driving motor. The rod moves the power breaker up and down from the base panel. The power is connected or disconnected between the idle gear and the motor gear. The rod is the rotary shaft of the power breaker, and operated by electric from a solenoid device. The smoke detector delivers an electric signal to the solenoid device through a controller(205).
