Abstract: This document describes techniques and devices for blood-solute calculation with a mobile device using non-invasive spectroscopy. A mobile device (502) includes a light source (504) that emits light toward an interferometer (508) that uses mirrors to separate and recombine the light. The interferometer directs the recombined light toward a person. Light reflected from, or transmitted through, the person is received through a reception port (506) to a photodetector (510) that outputs photodetector data that corresponds to a measured light intensity of the reflected and transmitted light as a function of a path length of the light or a mirror position of the interferometer. Based on the photodetector data, an interferogram is generated. Applying a technique such as a Fourier transform to the interferogram, a spectrum data set of the reflected and transmitted light is generated. Based on the spectrum data set, a concentration of solutes in the person's blood is calculated.

Abstract: Various systems, devices, and methods for social interaction measurement that preserve privacy are presented. An audio signal can be captured using a microphone. The audio signal can be processed using an audio-based machine learning model that is trained to detect the presence of speech. The audio signal can be discarded such that content of the audio signal is not stored after the audio signal is processed using the machine learning model. An indication of whether speech is present within the audio signal can be output based at least in part on processing the audio signal using the audio-based machine learning model.

Abstract: This document describes techniques and devices for Fourier-transform infrared (FT-IR) spectroscopy using a mobile device.

Abstract: A bedding apparatus is provided. The bedding apparatus includes a flexible body having a slit extending along a majority of the flexible body, thereby defining a first portion and a second portion. A plurality of fasteners extends along the slit that removably secures the first portion to the second portion. A placket extends along the slit on the first portion, such that the placket can fold over the plurality of fasteners to conceal the plurality of fasteners during use. In one use, the first portion and the second portion can be selectively and independently folded along the flexible body, such that a user can adjust the amount of the flexible body covering themselves without disturbing another individual utilizing the device.

Abstract: A washable, wearable biosensor that can gather sensor data, communicate the sensed data by wireless protocols, and permits the analysis of sensed data in real-time as a person goes about their normal lifestyle activities. The biosensor can be worn in multiple positions, can be put on or removed quickly without having to apply or remove gels and adhesives, and provides a snug, comfortable fit to gather data with minimal motion artifacts. The textile, wearable device can support integrated photoplethysmography, skin conductance, motion, and temperature sensors in a small wearable package. The supported sensors may be coupled to utilization devices by channel-sharing wireless protocols to enable the transmission of data from multiple users and multiple sensors (e.g. both sides of body, wrists or hands and feet, or multiple people).

Abstract: A collaborative online tele-operation system allows an audience of many participants to simultaneously share control of a single remote actor, such that the actions of the actor are based on the ongoing collective preferences of the audience.
