Abstract: This invention is augmented reality eyewear with a first mode which provides a clear, bright, wide-angle environment-only view when needed and a second mode which displays an augmented reality view when needed. This eyewear can have a virtual-object-display component which pivots between being on an eyewear sidepiece (e.g. temple) and being in front of a person's eye. It also includes a light emitter, wherein the virtual-object-display component reflects and/or refracts light from the light emitter toward the person's eye when the virtual-object-display component is in its second configuration.

Abstract: This invention is augmented reality eyewear which can transition between a real world viewing mode, a virtual reality viewing mode, and an augmented reality viewing mode. This eyewear shows bright opaque virtual objects in a portion of a person's field of view while providing the person with a clear view of the real world in the rest of their field of view. This eyewear includes an eyewear frame, an optical display, a lens, a plurality of selectively-movable (pivoting or rotating) micromirrors, and an array of electroconductive pathways.

Abstract: Disclosed herein is an article of smart clothing which automatically recognizes body configuration and motion. This smart clothing includes inertial motion units which are distal relative to selected joints and also sets of strain sensors which span those joints. The type of energy transmitted through a strain sensor can be electrical energy or light energy. Combined multivariate analysis of data from both inertial motion units and strain sensors provides more accurate recognition of body configuration and motion than data from either alone.

Abstract: A biometric wearable device (e.g. finger ring or smart watch) has optical sensors to measure body oxygenation level, hydration level, glucose level, heart rate, heart rate variability, and/or blood pressure. Light from light emitters is transmitted through body tissue and changes in the light are analyzed. The angles and/or vectors along which the light is transmitted through body tissue can be automatically changed by the device in order to scan different tissue regions and/or different tissue depths.

Abstract: This invention is an intrasaccular aneurysm occlusion device with a neck bridge with one or more proximal openings which is inserted into an aneurysm sac to cover the neck of the aneurysm sac. Embolic pieces (or flowable material) are inserted through the openings into the aneurysm sac. The neck bridge can have a convex first shape which is collapsed and inverted into a concave second shape. The neck bridge can be used in combination with a flexible distal net or mesh.

Abstract: This invention is an optical structure with a plurality of movable reflective elements. These reflective elements have first configurations which allow transmission of environmental light. These reflective elements have second configurations which block (or reduce) transmission of environmental light and which reflect light from a virtual-object display toward a person's eye. This enables display of a relatively-opaque virtual object in an area of a person's field of view, while providing the person with a relatively-clear view of their environment in the rest of their field of view.

Abstract: Disclosed herein are smart finger rings with light emitters and light receivers which collect biometric information concerning a person's health. Light from light emitters is received by light receivers after the light has been reflected by and/or transmitted through the person's finger. Several designs disclosed herein address the problem of size variation via innovative compressible, expandable, and/or adjustable-size components. Several designs disclosed herein address the problem of unintentional ring rotation via innovative movable components which change the circumferential locations and/or angles at which light beams from light emitters exit the ring toward a person's finger.

Abstract: This invention is a smart ring with spectroscopic sensors. Changes in the spectrum of light which are caused by interaction with (e.g. reflection by or transmission through) matter are analyzed to get information about the composition of that matter. In an example, light emitters can direct light outward toward an environmental object to get information concerning the molecular composition of the object. In an example, light emitters can direct light inward toward the surface of a person's finger to measure one or more biometric parameters.

Abstract: This invention is a protective face mask with a transparent portion which covers a wearer's nose and mouth, air intake and air exhaust ports on the front of the mask, one or more air impellors on the back of the wearer's head or neck, and one or more air tubes which conduct air between the air impellor and the transparent portion of the mask.

Abstract: In an example, a compact, dual-display optical structure for each eye of augmented reality eyewear can include: a first image display on a first side of a person's eye; a second image display on a second side of the eye; a first waveguide which reflects light rays from the first image display multiple times before those light rays are directed toward the eye; and a second waveguide which reflects light rays from the second image display multiple times before those light rays are directed toward the eye.

Abstract: Disclosed herein are wrist-worn devices with a camera which enable a person to record images of food or environmental scenes without contorting their arm. Devices can allow a camera to be moved independently from the rest of the device. A camera can be on a flip-up display with features which decrease the chances of the display snagging on an object and breaking off. A camera can be on the rim of an enclosure held on the dorsal side of a wrist with a bifurcating band, so that the band does not block the camera's view.

Abstract: This invention is a device with an expandable light-emitting display which is worn on a persons' wrist and/or lower arm. The expandable display can be a flexible display which can be rolled and then expanded by unrolling it out from a housing. In an example, the flexibility of the expandable second display can be adjusted. The second display can be made flexible so that is can be rolled around a roller, but can also be made rigid for use as a touch screen in an expanded state.

Abstract: This invention is a method, device, or system to guide a person concerning how to operate a conventional phone to record more-accurate images of a pathology or injury (e.g. such as a wound or skin lesion) on a body for remote medical evaluation purposes. In an example, machine learning and/or artificial intelligence can be used to guide the person concerning how to move a phone along a virtual arcuate path or shape in space over, across, or around the pathology or injury. In an example, this guidance can be auditory, visual, and/or tactile.
