Abstract: A sample analysis device is provided, the device comprising a frame adapted to accept at least one analysis apparatus, with each analysis apparatus having an analysis distance associated therewith. A eucentric goniometer is operably engaged with the frame and is adapted to eucentrically support a sample at a eucentric point within a reference system defined by the eucentric goniometer. The reference system of the eucentric goniometer is independent of the analysis distance. An axial adjustment device is operably engaged with at least one of the frame and the eucentric goniometer and is configured to coincidentally position the eucentric point and the analysis distance for the respective analysis apparatus. An associated device and method are also provided.

Abstract: This invention provides a continuous display with non-uniform pixel density, forming a foveated display. A single, continuous display has a higher pixel density at the center of the display than at the periphery of the display. Where two continuous displays are used in accordance with the present invention, the central forward gaze of the viewer's image will be displayed in high resolution while the leftmost portion of the left eye display will be in low resolution and the rightmost portion of the right eye display will be in low resolution. The pixel resolution of the visual display may correspond to the visual acuity of the human eye. A foveated image display system using a continuous display with non-uniform pixel density increases the field of view while reducing the image bandwidth. A foveated image display system may be hardware-based by employing anamorphic lenses or sensors rather than relying upon image interpolation to modify the resolution of the resultant image data communicated to the continuous display with non-uniform pixel density.

Abstract: The present invention provides for an improved electromagnetic radiation detector having a micromachined electrostatic chopping device. The MEMS flexible film chopping device provides reliability, efficiency, noise reduction and temperature fluctuation compensation capabilities to the associated electromagnetic radiation detector. An electromagnetic radiation detector having an electrostatic chopper device comprises a detector material element, first and second electrodes in electrical contact with the detector material element and electrically isolated from one another. Additionally, the chopper device will incorporate a flexible film actuator overlying the detector material layer and moveable relative thereto. The flexible film actuator will typically include an electrode element and a biasing element such that the actuator remains in a fully curled, open state absent electrostatic voltage and moves to a fully uncurled, closed state upon the application of electrostatic voltage. Arrays that incorporate a plurality of electromagnetic radiation detectors and/or electrostatic chopping devices are additionally provided for.

Abstract: A miniature electrical relay including a piezoelectric actuating element where the piezoelectric actuating element includes a piezoelectric thin-film material sandwiched in between two metal electrode layers that function as piezoelectric electrodes. The metal electrode layers are connected to a positive and negative terminal, respectively, of a power source, which results in actuation of the piezoelectric actuating element. The piezoelectric actuating element is affixed to a deformable metal contact through an insulating layer, such that when actuated, the piezoelectric actuating element selectively deforms the deformable metal contact to cause the contact to move into or out of electrical and mechanical connection with a fixed metal contact. A method of making the miniature piezoelectric includes providing a support structure, depositing a first contact on a first portion of the support structure, depositing a second contact on a second portion of the support structure, wherein the second contact is deformable with respect to the first contact for selectively engaging the first contact, and fabricating a piezoelectric actuator that selectively deforms the second contact relative to the first contact.
