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.

Abstract: A person's food consumption can be automatically tracked by a finger ring or smart watch with a motion sensor and a camera on its ventral portion. The camera is activated to record images when the device is waved over food. The images are analyzed to identify food types and quantities. A system for tracking food consumption can include a finger ring with a camera which is worn on a person's dominant arm and a smart watch worn on the person's non-dominant arm, wherein images recorded by the camera are displayed by the smart watch.

Abstract: This invention is a head-worn device (e.g. headband, halo, or headset) with sensors (e.g. electrodes) which record brain activity. In an example, the device can be undulating with concave undulations which rest on the tops of a person's ears. In an example, the device can further comprise right side and left side ear prongs (e.g. arms, segments, or portions) which curve around the posterior and upper surfaces of a person's right and left ears.

Abstract: Motion recognition clothing is smart clothing which measures changes in a person's body configuration and motion. In an example, a combination of upper-body and lower-body motion recognition clothing can measure changes in full-body configuration and motion. Selected body joints are each spanned by a plurality of flexible energy pathways. Each flexible energy pathway is in communication with an energy emitter and an energy receiver. Body joint movements deform the energy pathways, this deformation changes energy transmission through the energy pathways, and changes in energy transmission are then analyzed to measure body configuration and motion.

Abstract: A wrist-worn device such as a smart watch or band has a plurality of displays with a first non-coplanar configuration and a second coplanar configuration. When a larger display area is not needed, then the device is changed into the more-compact first configuration. When a larger display area is needed, then the device is changed into the larger-size second configuration.

Abstract: A wearable device for measuring biometric parameters includes a circular or polygonal array of sets of light emitters and light receivers. Light transmitted through body tissue is received and analyzed to measure one or more biometric parameters such as oxygenation level, heart rate, heart rate variability, blood pressure, hydration level, and/or blood glucose level. Each set of light emitters includes light emitters which emit light of different colors. This device can also include one or more compressible opaque light barriers which surround light receivers.

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 can be embodied in methods and systems for reducing a person's consumption of unhealthy food by providing the person with haptic and/or tactile sensations in response to detection of unhealthy food near the person and/or detection of consumption of unhealthy food by the person. Detection of unhealthy food near the person can be done using a camera on a device worn by the person. Detection of consumption of unhealthy food by the person can be done using a food consumption sensor on a device worn by the person. Haptic and/or tactile sensations can be vibrations.

Abstract: This invention is eyewear (e.g. eyeglasses) with electrodes (e.g. EEG sensors) which collect brain activity data (e.g. electroencephalographic data) which can be used to predict and/or detect health events (e.g. epileptic seizure, stroke, or heart attack) or function as a BCI (Brain-to-Computer Interface) for communication. There can be anterior and posterior electrodes on the eyewear temple and the temple can have an upward and/or inward curving wave or arm. A posterior electrode can have multiple electroconductive protrusions to help penetrate between strands of hair.

Abstract: This invention is a method or system which uses machine learning and/or artificial intelligence (AI) to adjust, manage, and/or control the operation of one or more implanted medical devices. This method or system identifies the lagged effects of operating parameters of the one or more implanted medical devices on a person's biometric indicators and then adjusts the operating parameters of the one or more implanted medical devices to change the values of the biometric indicators in a desired direction and/or by a desired amount.

Abstract: This invention is Motion Recognition Clothing™ which measures the motion and/or configuration of a person's body using an energy-conducting mesh with a plurality of energy pathways. Energy input components direct energy into the pathways at a first set of locations. Energy sensors measure energy flow through the energy pathways from a second set of locations. As the person's body moves, the mesh stretches, elongates, and/or twists, which changes the flows of energy through pathways. These changes are then analyzed to estimate the motion and/or configuration of the person's body.

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.

This dry electrode has a plurality of electroconductive protrusions which extend out from a base toward the surface of a person's head. These protrusions slide through hair without being so narrow that they do not get good electrical contact and without being so stiff that they are uncomfortable for extended wear.

Abstract: A device, system, or method for estimating a person’s food consumption comprises two types of wearable sensors. A first type of sensor collects data to detect when the person consumes food. A second type of sensor is activated when data from the first type of sensor indicates that the person is consuming food. Data from these sensors are analyzed to estimate the types and amounts of food consumed by the person. This device, system, or method then provides feedback and/or coaching to the person to improve their eating habits.

Abstract: This invention is a system for nutritional monitoring and management which includes a camera, a spectroscopic sensor, a fiducial component, a wearable biometric sensor, a smart utensil or dish, a passive feedback mechanism which provides a person with information concerning food item types and/or quantities, and an active stimulus mechanism which modifies the person's food-related physiological processes. This system can help a person to improve their dietary habits and health.

Abstract: This invention is a smart watch with variable-configuration displays which combine to provide a larger combined display when needed. When a person does not need a large display area, then a plurality of displays on the watch fit around the person's wrist and/or arm in a relatively compact first configuration. When the person needs a larger display area, then the plurality of displays are moved into a second configuration which creates a large, coplanar, combined display.
