Abstract: Disclosed herein is a pair of EEG glasses or other electroencephalographic eyewear comprising an eyewear frame with a frontpiece and two sidepieces (e.g. temples), wherein there is an arcuate arm which extends out from the sidepiece toward the person's head and an electrode on the arcuate protrusion. The electrode collects data concerning the person's brain activity.

Abstract: A wearable ring or band can have spectroscopic sensors on its inner circumference. The ring or band can change: the angles at which light beams from sensors are transmitted; the radial locations of sensors around the inner circumference; and/or the distances between sensors and a person's body. The ring or band can also have an expandable and/or compressible chamber or layer on its inner circumference. The ring or band can also have a flexible, elastic, and/or articulated segment as part of its circumference.

Abstract: A wearable device or system for monitoring food consumption can include a wrist-worn or finger-worn device which is worn by a person, a motion sensor on the wrist-worn or finger-worn device, eyewear which is worn by the person, and a camera on the eyewear which is activated to record food images when analysis of data from the motion sensor detects that the person is eating. This device can be used alone or as part of a closed-loop glucose level management system.

Abstract: A biometric wearable device is embodied in a finger ring or smart watch with radiowave or microwave energy emitters/transmitters and energy receivers to measure the level of a biometric parameter such as body oxygenation, hydration, or glucose level.

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: 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: 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: Wearable Ring or Band with Close-Fitting Spectroscopic Sensors A wearable ring or band can have spectroscopic sensors on its inner circumference. The ring or band can change: the angles at which light beams from sensors are transmitted; the radial locations of sensors around the inner circumference; and/or the distances between sensors and a person's body. The ring or band can also have an expandable and/or compressible chamber or layer on its inner circumference.

Abstract: Disclosed herein is a system for cardiac rhythm management including an implanted cardiac pacemaker and a biometric finger ring. This system ensures good oxygenation of a person's body extremities. The finger ring includes optical sensors which measure the person's blood oxygenation level. The operation of the implanted cardiac pacemaker is adjusted based on combined analysis of motion data from the pacemaker, motion data from the finger ring, and blood oxygenation level data from the biometric finger ring.

Abstract: A wearable brain activity monitor with electromagnetic sensors can be embodied in an ear-worn device. A first portion of the device can span a portion of the lateral perimeter of a person's ear and a second portion of the device can be inserted into the person's ear canal. In an example, the first portion can loop around 25% to 75% of the lateral perimeter of the person's ear.

Abstract: This invention is an article of clothing with electromyographic (EMG) sensors which measures body motion and/or muscle activity.

Abstract: An electrode can comprise a plurality of flexible longitudinal electroconductive protrusions which deform when pressed against a person's head. Proximal ends of the protrusions are adjacent to each other and have a first degree of curvature in a pre-deformation configuration. Proximal ends of the protrusions are apart from each other and have a second degree of curvature in a post-deformation configuration. The proximal-divergence of the ends of the protrusions enables them to slide between strands of hair to enable good electrical communication with the surface of the person's head.
