Abstract: A trigger sense circuit includes a pseudo-differential comparator circuit in signal communication with a pixel array. The pseudo-differential comparator circuit includes a first input in signal communication with a reference pixel group included in the pixel array to receive a pixel reference voltage, and a second input in signal communication with a target pixel group included in the pixel array to receive a pixel target voltage. The pseudo-differential comparator circuit is configured to selectively operate in a calibration mode to remove false trigger events and a comparison mode to detect at least one overheated pixel included in the target pixel group.

Abstract: An example integrated transformer is provided having a core. A first set of windings encircles a first region around the core. A second set of windings encircles a second region around the core, wherein the first region and the second region are not the same. At least one insert separates magnetic flux induced by the first set of windings and the second set of windings enabling increased magnetic inductance with reduced winding losses.

Abstract: A bearing system for a control surface of a high speed flight vehicle includes a bearing configured to support the control surface, and a pressurized lubricant chamber containing a lubricant for the bearing. The lubricant contained in the lubricant chamber is in a first phase. The lubricant chamber is subject to heating by a heated aerothermal environment (an environment external to the high speed flight vehicle). The lubricant in the first phase, therefore, is configured to transition from the first phase to a second phase when the lubricant chamber is heated by the heated aerothermal environment. The lubricant in the second phase is configured to flow from the lubricant chamber to the bearing to lubricate and cool the bearing via a flow-based cooling effect.

Abstract: A multi-flexure payload isolation device for isolating a payload from outside forces. The device can include a housing comprising an interior cavity configured to receive and support the payload. The device can further include a first flexure and a second flexure, each including a plurality of spokes made of a pseudoelastic shape-memory alloy anchored to the housing and configured to support the payload from the housing through an opening in the housing. The first and second flexures can each further include a common hub attached to a side of the payload and disposed in the opening in the housing wherein the each of the pluralities of spokes are anchored to the respective common hub.
