Provided is a method and system for detecting rotational movement of a camera. Three pairs of accelerometers are located in the camera, with the motion sensing axes of each of the accelerometers in each of the pairs parallel to one another. The accelerometers are relatively positioned in the camera such that the planes formed by the motion sensing axes of each of the pairs of accelerometers are substantially mutually orthogonal.

An electron emitter that includes a metal film having a set of layers that are selected and arranged to adhere the metal film to a remainder of a structure of the electron emitter while avoiding electron loss in the metal film. A multiple layer metal film according to the present techniques enables a balance among adhesion properties, metal diffusion, and oxide properties that might otherwise hinder the performance of an electron emitter.

A method is presented for forming pores within a central area of a semi-conductive or conductive surface. The method includes forming a semi-conductive or conductive surface on a substrate. This semi-conductive or conductive surface is formed in a manner ensuring that upon application of an electric field at the semi-conductive or conductive surface an intensity of the electric field at a central area of the surface is at least as great as an intensity of the electric field at a perimeter of the surface. Finally, the method includes anodizing the semi-conductive or conductive surface by generating the electric field at the semi-conductive or conductive surface to form a porous region within the semi-conductive or conductive surface.

A field emission device, which among other things may be used within an ultra-high density storage system, is disclosed. The emitter device includes an emitter electrode, an extractor electrode, and a solid-state field controlled emitter that utilizes a Schottky metal-semiconductor junction or barrier. The Schottky metal-semiconductor barrier is formed on the emitter electrode and electrically couples with the extractor electrode such that when an electric potential is placed between the emitter electrode and the extractor electrode, a field emission of electrons is generated from an exposed surface of the semiconductor layer. Further, the Schottky metal may be selected from typical conducting layers such as platinum, gold, silver, or a conductive semiconductor layer that is able to provide a high electron pool at the barrier. The semiconductor layer placed on the Schottky metal is typically very weakly conductive of n-type and has a wide band gap in order to create conditions conducive to creating induced negative electron affinity at applied fields necessary to provide electron emission. One type of wide band-gap material can be selected from titanium dioxide or titanium nitride or other comparable materials.

Provided is a curved light guide screen. A plurality of vertically aligned light guides are arranged into light guide magnifying layers. Spacers are disposed between any two adjacent light guide magnifying layers, proximate to the magnifying output ends, to position the magnifying layers and define an orientation for the magnifying output ends. A curved viewing surface is defined having a concave, convex or complex curvature shape depending on the size, shape and positioning of the spacers. The spacers may have a variety of shapes, and may be flexible, semi-rigid or rigid. A case houses the light guide magnifying layers and spacers, as well as an image source and associated lenses. A related method of making a curved light guide screen is also provided.
