Abstract: Adjustable load leveler apparatus and related methods for use with automotive manufacturing systems are disclosed. A disclosed automotive manufacturing system includes a hoist supported by a support structure and configured to carry a vehicle component. The automotive manufacturing system also includes a load leveler mechanism attached to the hoist. The load leveler mechanism includes a frame, a weight movably coupled to the frame, and an actuator operatively coupled to the weight. The automotive manufacturing system also includes control circuitry connected to the actuator and an input device connected to the control circuitry and configured to generate input data in response to a user interacting with the input device. The control circuitry is configured to move, via the actuator, the weight relative to the hoist based on the input data to adjust a levelness of the hoist.

Abstract: An optical combiner includes a lightguide having an input region, an output region, a relay region intermediate between the input region and the output region, and one or more stress raisers positioned to define a line of weakness in the lightguide. The line of weakness is intermediate between the input region and the output region and extends across the relay region. An in-coupler is disposed at the input region to receive an incident light with a field of view and couple the incident light into the lightguide. An out-coupler is disposed at the output region to couple light out of the lightguide. The optical combiner may be integrated with one or more lenses for use as a combiner lens in a wearable heads-up display.

Abstract: A face replacement system for replacing a target face with a source face can include a facial landmark determination model having a cascade multichannel convolutional neural network (CMC-CNN) to process both the target and the source face. A face warping module is able to warp the source face using determined facial landmarks that match the determined facial landmarks of the target face, and a face selection module is able to select a facial region of interest in the source face. An image blending module is used to blend the target face with the selected source region of interest.

Abstract: Systems, articles, and methods that integrate photopolymer film with eyeglass lenses are described. One or more hologram(s) may be recorded into/onto the photopolymer film to enable the lens to be used as a transparent holographic combiner in a wearable heads-up display employing an image source, such as a microdisplay or a scanning laser projector. The methods of integrating photopolymer film with eyeglass lenses include: positioning photopolymer film in a lens mold and casting the lens around the photopolymer film; sandwiching photopolymer film in between two portions of a lens; applying photopolymer film to a concave surface of a lens; and/or affixing a planar carrier (with photopolymer film thereon) to two points across a length of a concave surface of a lens. Respective lenses manufactured/adapted by each of these processes are also described.

Abstract: A wearable electronic device includes a body defining an aperture therethrough, sized and shaped to receive a digit of a user. The wearable electronic device may include a processor housed in the body and an input device at least partially extending from an outer surface of the body to receive input from another digit of the user. The input device has an actuating surface that is movable between a first position and a second position. Movement of the actuating surface between the first position and second position provides an input to the processor. The wearable electronic device includes a transmitter coupled to the processor and configured to send electronic transmissions to an external electronic device, the electronic transmissions corresponding to the inputs received from the user, and a power source for providing power to the processor, the input device, and the transmitter.

Abstract: A wearable electronic device is provided herein. The wearable electronic device includes a body defining an aperture therethrough. The aperture is sized and shaped to receive a finger of a user. The wearable electronic device further includes a computer processor and an input device at least partially extending from an inner surface of the body. The input device is movable between a first position and a second position. Movement of the input device between the first position and second position provides an input to the processor. The electronic wearable device also includes a transmitter coupled to the computer processor and configured to send electronic transmissions to an external electronic device. The electronic transmissions correspond to the input. The electronic wearable device also includes a power source for providing power to the computer processor, the input device and the transmitter.

Abstract: Systems, devices, and methods for optical engines and laser projectors that are well-suited for use in wearable heads-up displays (WHUDs) are described. Generally, the optical engines of the present disclosure integrate a plurality of laser diodes (e.g., 3 laser diodes, 4 laser diodes) within a single, hermetically or partially hermetically sealed, encapsulated package. The optical engines include an optical director element that includes a curved reflective surface (e.g., parabolic cylinder) that redirects laser light beams and collimates the same along the fast axes thereof. Such optical engines may have various advantages over existing designs including, for example, smaller volumes, better manufacturability, faster modulation speed, etc. WHUDs that employ such optical engines and laser projectors are also described.

Abstract: Systems, devices, and methods for laser eye tracking are described. Laser eye tracking involves scanning laser light over the eye and detecting diffuse reflections of the laser light with one or more photodetector(s). While conventional camera-based eye tracking techniques rely on detecting and identifying specific reflections (i.e., Purkinje images such as the “glint”), the laser eye tracking techniques described herein detect and identify a reduction in reflection intensity due to transmission of laser light through the pupil and/or increased diffusivity of reflections from the cornea relative to reflections from the sclera. This effect is referred to herein as the “corneal shadow” effect. Laser eye tracking uses considerably less power than conventional camera-based eye tracking techniques. As a result, the laser eye tracking techniques described herein do not add significant power demands to a system and can be implemented in wearable heads-up displays without adding significant volume to the system battery.

Abstract: Systems, devices, and methods of manufacturing optical engines and laser projectors that are well-suited for use in wearable heads-up displays (WHUDs) are described. Generally, the optical engines of the present disclosure integrate a plurality of laser diodes (e.g., 3 laser diodes, 4 laser diodes) within a single, hermetically or partially hermetically sealed, encapsulated package. Photonic integrated circuits having grating couplers thereon may be used to wavelength multiplex beams of light emitted by the plurality of laser diodes into a coaxially superimposed aggregate beam. Such optical engines may have various advantages over existing designs including, for example, smaller volumes, better manufacturability, faster modulation speed, etc. WHUDs that employ such optical engines and laser projectors are also described.
