  • Patent number: 12046118
    Abstract: A method of detecting occupants within a vehicle includes receiving camera data, thermal data and radar data with respect to the vehicle. The received data is stored to at least a first buffer and a second buffer, wherein the first buffer has a length associated with a first duration of time and the second buffer has a length associated with a second duration of time greater than the first duration of time. The camera data, thermal data, and radar data stored in the respective first and second buffers is analyzed to detect and track camera-based objects, radar-based objects, and thermal-based objects, which are utilized to generate an output indicating whether an occupant was detected.

  • Publication number: 20240077784
    Abstract: Described is phased metalens depth of focus increase for camera focusing. An objective camera lens is configured to provide a focus window across multiple radial zones within a field of view. A camera imager is configured to capture an image of the field of view. When at least two of the radial zones have different back focal lengths relative the imager and the objective lens, a phased metalens is positioned between the objective lens and the camera imager. The metalens is configured to compensate for defocus caused by the different back focal lengths by increasing, across the radial zones within the field of view, a depth of the focus window. The metalens improves focus across the field of view, which prevents variations in objective lens characteristics from reducing image quality.

  • Patent number: 11914679
    Abstract: This document describes techniques, apparatuses, and systems for enabling multispectral object-detection with thermal imaging. A thermal sensor, a multispectral stereo camera system, and an illumination system are used in combination to provide a multispectral object-detection system for use with safety or driving systems for autonomous and semi-autonomous vehicles. The illumination system can provide illumination for the stereo camera system and serve as a range-finder that can determine a distance between the stereo camera system and an object in the system's field-of-view. The stereo camera system can include one or more of various camera or sensor technologies, including infrared or near-infrared, thermal imaging, or visible light. The system can be used to detect objects in the field-of-view, determine a distance to the object, and estimate the object's size and relative motion.

  • Patent number: 11818452
    Abstract: A camera includes a phased metalens positioned between an objective lens and an imager of the camera. The phased metalens is configured to adjust a focus plane of an image in a field of view of the camera in response to changes in an operating temperature of the camera. The phased metalens adjusts the focus plane for multiple frequencies or wavelengths light such that all light wave-fronts exiting the phased metalens arrive at the imager at a same time.

  • Publication number: 20230358989
    Abstract: Described is camera focusing including lens centration estimation using variable focal length phased metalenses. Camera modular alignment and test (CMAT) equipment checks the modular transfer function (MTF) performance of lenses and an image sensor. The CMAT equipment positions a variable focal length phased metalens between the lenses and the image sensor. The metalens includes multiple segments that provide a variable focus depending on distance and angle from boresight of the image sensor. By measuring optical characteristics of the lenses at two opposing segments of the metalens, defocusing effects and a lens centration tilt vector can be computed. Repositioning the lenses to align the centration tilt vector with the boresight of the image sensor improves the MTF performance. A final camera assembly with lenses in precise alignment with the image sensor can be produced, which may improve production output by increasing pass rate at an end of line tester.

  • Publication number: 20230194251
    Abstract: The techniques of this disclosure relate to actively selecting lenses for camera focus processes. Lenses to be used during camera assembly are chosen based on whether their pairing with a specific set of production components can satisfy focus performance criteria of end of line test. Test equipment may check the lenses by dry-fit aligning them to a particular set of production components. If minimum focus performance cannot be achieved, then a different set of lenses are used to with that set of production components to produce a final camera assembly. This way, because the lenses are actively selected during production to achieve satisfactory focus performance of the EOLT, each final camera assembly is more likely to pass the EOLT, thereby improving camera production output.

  • Publication number: 20230199311
    Abstract: The techniques of this disclosure relate to actively selecting lenses for camera focus processes. Test equipment may check lenses by dry-fit aligning them to a particular set of production components. If minimum focus performance cannot be achieved, then the lenses go unused for a final camera assembly. In certain situations, the unused set of lenses is salvageable for use in another camera assembly. Advanced CMAT equipment may compute and apply a rotation for unused lenses to improve their focus performance the next time they are used in a final assembly. A maximum number of attempts to rotationally fix a set of lenses may be observed to avoid trying the same lenses again and again, possibly without ever having success. This way, because the lenses actively selected can also be rotated during production, final camera assemblies can be produced that are likely to pass the EOLT, and by minimizing waste.
