Abstract: A modular display assembly comprising a light emitting or transmitting display panel and a glass panel wherein: the display and glass panel are separated from each other by a frame assembly; and the display is coupled to the frame assembly by at least one elastic isolator.

Abstract: Apparatus and methods relating to display stacks wherein one or more index matching layers are utilized to minimize reflectance at the boundaries of otherwise adjacent layers. More particularly, the present invention is directed to methods and apparatus relating to a multilayer display stack comprising a glass layer, a first index matching layer, a first intermediate layer, a second index matching layer, a second intermediate layer, and a light emitting display panel wherein: the glass layer, first index matching layer, first intermediate layer, second index matching layer, and second intermediate layer are each transparent or translucent, and comprise an index of refraction; the index of refraction of the first index matching layer is between the index of refraction of the glass layer and the first intermediate layer; and the index of refraction of the second index matching layer is between the index of refraction of the first intermediate layer and the second intermediate layer.

Abstract: A system and method for controlling the cavity length of a ring laser gyroscope to properly tune the resonant wavelengths of the ring laser gyroscope during moments when experiencing sudden shocks or high g force accelerations. The system controls the position of a movable mirror in the laser cavity of the gyroscope to control the length of the laser cavity. The system measures the acceleration experienced by the laser cavity, wherein the position of the movable mirror is adjusted to counteract the effects of the acceleration on the movable mirror in a real-time response to the measured acceleration. By adjusting the position of the movable mirror, the resonant wavelengths propagating in the ring laser gyroscope will be maintained at their desired intensity and continue to lase even after experiencing this acceleration.
