Abstract: Imaging systems and methods for imaging using the same color or monochromatic image sensor, wherein imaging can be switched between at least two imaging modes, for example between a visible imaging mode and an IR imaging mode, without moving any system component from a given position in an optical path between an imaged object and the image sensor. In an example, a system includes an image sensor, a tunable spectral filter and a multi-bandpass filter, the tunable spectral filter and the multi-bandpass filter arranged in a common optical path between an object and the image sensor, and a controller configured and operable to position the tunable spectral filter in a plurality of operation states related to a plurality of imaging modes.

Abstract: Tunable MEMS etalon devices comprising: a front minor and a back mirror, the front and back mirrors separated in an initial pre-stressed un-actuated etalon state by a gap having a pre-stressed un-actuated gap size determined by a back stopper structure in physical contact with the front mirror and back mirrors, the etalon configured to assume at least one actuated state in which the gap has an actuated gap size gap greater than the pre-stressed un-actuated gap size; an anchor structure, a frame structure fixedly coupled to the front mirror at a first surface thereof that faces incoming light, and a flexure structure attached to the anchor structure and to the frame structure but not attached to the front mirror, and a spacer structure separating the anchor structure from the back mirror, and wherein the front mirror and the spacer structure are formed in a same single glass layer.

Abstract: A power supply comprising a DC to DC converter coupled to a current limit controller and an accumulator. The accumulator discharges while the current limit controller limits the current draw of the DC to DC converter.

Abstract: A power supply comprising a DC to DC converter coupled to a current limited controller and an accumulator is disclosed, where the DC to DC converter may be a switch-mode DC to DC converter. The current limit controller may be configured to limit a current draw of the switch-mode DC to DC converter. The accumulator may be configured to discharge to an output terminal of the DC to DC converter while the current limit controller limits the current draw of the DC to DC converter.
