Adaptable lens assemblies, optoelectronic components, and associated methods of manufacturing are provided. An example optoelectronic component includes a printed circuit board (PCB) and an adaptable lens assembly. The adaptable lens assembly includes a lens packaging structure supporting an optical lens at a focal distance and a lens support structure. The lens support structure defines a first side configured to support the lens packaging structure and maintain the focal distance and a second side removably attached to the PCB. The attachment between the second side of the lens support structure and the PCB is configured to enable selective attachment and detachment of the lens support structure and lens packaging structure supported thereon without causing damage to the PCB.

A cellular trail camera system is disclosed and may include a housing; a mounting bracket for mounting the camera; a visible sensor; an infrared sensor; and a plurality of Fresnel lenses each operable to be individually mounted to or with the infrared sensor and to focus infrared light to the infrared sensor from a different direction. One of the Fresnel lenses may be mounted to or with the housing during operation. The housing may include a wireless transceiver, which may communicate via a cellular network. The camera may communicate with a wireless communication device via the wireless transceiver. The camera may communicate images and/or video to the wireless device. The infrared sensor may include a plurality of elements. The camera may be powered by a solar cell that is mounted on the camera or remote from the camera. The visible sensor may be activated when the infrared sensor detects a heat-generating object.

In a method, it is determined that a detachable lens is mounted on an image capture device in a first orientation. A first image of a controlled scene is captured with the detachable lens mounted in the first orientation. It is determined that the detachable lens is mounted on the image capture device in a second orientation that is rotated approximately 180 degrees from the first orientation. A second image of the controlled scene is captured with the detachable lens in the second orientation. A first image circle center of the first image is determined. A second image circle center of the second image is determined. An average image circle center is determined, based on the first image circle center and the second image circle center. The average image circle center is provided to an image stabilization algorithm when the detachable lens is mounted on the image capture device.

An image sensor attached to a printed circuit board is installed in a camera. A holder includes first and second rails comprising first and second printed circuit boards, respectively, and the holder is fastened to a lens mount of the camera. The holder may be fastened to captively hold the image sensor, and the image sensor may be resiliently supported when captively held. A gripper grasps the image sensor proximate to the holder and aligns the image sensor to an aligned position of the image sensor relative to the lens mount. The image sensor may be moved to the aligned position after directing an image toward the image sensor to produce a processed image for determining relative alignment. The printed circuit board is soldered to the first and/or second printed circuit board such that the holder fixedly holds the image sensor so it is unmovable in its aligned position.

A method of additive manufacture is disclosed. The method may include creating, by a 3D printer contained within an enclosure, a part having a weight greater than or equal to 2,000 kilograms. A gas management system may maintain gaseous oxygen within the enclosure atmospheric level. In some embodiments, a wheeled vehicle may transport the part from inside the enclosure, through an airlock, as the airlock operates to buffer between a gaseous environment within the enclosure and a gaseous environment outside the enclosure, and to a location exterior to both the enclosure and the airlock.
