Abstract: An apparatus includes a detector that measures radiation. The apparatus also includes a window that is relationally coupled to the detector and a shield, so that the window is in between the detector and the shield. The apparatus further includes the shield that emits substantially constant radiation, and substantially blocks radiation from a camera housing at least partially surrounding the shield, so that the detector measures radiation passing through an optical system and the shield.

Abstract: A thermal imaging camera includes an infrared detector operable to capture thermal video data, a processor coupled to the infrared detector and operable to process the thermal video data, and at least one communications interface operable to communicate the processed thermal video data to a consumer mobile device coupled thereto.

Abstract: Embodiments of the invention are directed to a springless athermal lens assembly. In one embodiment, a spacer of a springless athermal lens assembly may compensate for defocus of the camera system due to thermal expansion of the lens assembly through the coupling of a spacer to an inner barrel and an outer barrel. The inner barrel comprises a lens cell assembly and a body. The outer barrel comprises a body. The spacer comprises a body having an inner surface and an outer surface. The outer surface of the spacer body is configured to be physically coupled to outer barrel body and the inner surface of the spacer body is configured to be physically coupled to the inner barrel body. A retainer ring is configured to engage with the outer surface of the spacer body and provide a radial force against the outer surface of the spacer body to securably engage the inner surface of the spacer body with the inner barrel body.

Abstract: Embodiments of the invention are directed to a springless athermal lens assembly. In one embodiment, a spacer of a springless athermal lens assembly may compensate for defocus of the camera system due to thermal expansion of the lens assembly through micro wedge mechanisms coupling the spacer to an inner and outer barrel. The inner barrel comprises a lens cell assembly and a body having a micro wedge slot. The outer barrel comprises a body having a micro wedge slot. The spacer comprises an inner barrel micro wedge and an outer barrel micro wedge. The spacer is configured to be physically coupled to the inner barrel through engagement of the inner barrel micro wedge and the inner barrel micro wedge slot. Further, the spacer is configured to be physically coupled to the outer barrel through the engagement of the outer barrel micro wedge and the outer barrel micro wedge slot.

Abstract: A metal structure for an integrated circuit having a plurality of contact pads and a patterned metallization protected by an overcoat layer. The structure comprises a plurality of windows in the overcoat, selectively exposing the chip metallization, wherein the windows are spaced apart by less than 150 &mgr;m center to center. A metal column is positioned on each of the windows; the preferred metal is copper; the column has a height-to-width aspect ratio larger than 1.25 and an upper surface wettable by re-flowable metal. The preferred column height-to-width aspect ratio is between 2.0 and 4.0, operable to absorb thermomechanical stress. A cap of a re-flowable metal is positioned on each of the columns. The metal structure is used for attaching the IC chip to an external part.
