A wearable computing device includes one or more processors, memory and a physiological metric sensor system, including a light source configured to direct light into tissue of a user wearing the wearable computing device, a light detector implemented a distance away from the light source and configured to detect light from the light source that reflects back from the user, and a light-blocking portion implemented between the light source and the light detector.

The optical properties of the glass ceramic region and the positioning of the glass ceramic region with respect to the optical component can affect the performance of the optical component, the visual appearance of the optical component, or both.

A system and method of tracking activity includes a motion sensor, a light source and a light detector. The light detector is configured to capture an amount of the light that is reflected back to the light detector, at least a first portion of the light reflected back to the light detector is reflected from a blood vessel disposed under a skin adjacent to the housing. A processor is in communication with the motion sensor and the light detector and can process the reflected light to identify heart beats and produce an indication of a heart rate. The indication of the heart rate can be displayed on the display screen as an option, in addition to the metrics that quantify the motion data.

This relates to systems and methods for determining one or more of a user's physiological signals. The one or more of the user's physiological signals can be determined by measuring pulsatile blood volume changes. Motion artifacts included in the signals can be canceled or reduced by measuring non-pulsatile blood volume changes and adjusting the signal to account for the non-pulsatile blood information. Non-pulsatile blood volume changes can be measured using at least one set of light emitter-light sensor. The light emitter can be located in close proximity (e.g., less than or equal to 1 mm away) to the light sensor, thereby limiting light emitted by the light emitter to blood volume without interacting with one or more blood vessels and/or arterioles. In some examples, the systems can further include an accelerometer configured to measure the user's acceleration, and the acceleration signal can be additionally be used for compensating for motion artifacts.

A medical imaging device configured to spatially resolve recording of multispectral video data of an examination area of a patient including a light source having multiple optical emitters with different wavelengths in the visible and NIR spectral range. The light source has an emitter whose wavelength lies in the range of ±50% of its half-width around the intersection of the blue and green filter curves or the green and red filter curves, and the exposure control and the data processing means are arranged to separately detect the affected two of the red and green or the green and blue colour signals in an exposure pattern with activation of the emitter at the intersection point and to evaluate them in the multispectral analysis with mutually different wavelengths shifted by the two affected filter curves as two supporting point wavelengths.

Light is irradiated to a finger of a subject and received from the finger of the subject to extract a pulse wave signal, generates an optimized pulse wave signal in a desired type by sampling the extracted pulse wave signal according to a predetermined sampling condition and normalizes the generated pulse wave signal, the entire segment of the normalized pulse signal is divided into a plurality of window segments to detect a pulse wave amplitude value with respect to a pulse wave signal for each window, a first eigenvector for each subject corresponding to a pulse wave amplitude value of the entire window segment is extracted by using a linear discriminant analysis and then the first eigenvector per subject is compared with a threshold, determines distribution of eigenvectors for each subject compared to the threshold and thus a characteristic of the corresponding subject is diagnosed.
