Abstract: The present invention may be used to determine whether a user of a device, such as a mobile device, is facing a mirror and also pointing their mobile device at an image of themselves in this mirror. The present invention may use machine learning real-time video analysis and/or mobile device sensors to make that determination.

Abstract: Devices, systems, and methods for monitoring respiration using surface temperature, humidity, air pressure, carbon dioxide gas sensors, pulse oximetry sensors and electromyography sensors, and/or acceleration sensors to obtain information related to respiration rate (RR), exhalation/inhalation strength, exhalation/inhalation volume, exhalation/inhalation acceleration, and/or exhalation/inhalation regularity.

Abstract: Devices and methods for determining the position of a device relative to a person using the device, or the position of a part of a user's body relative to the user. One or more thermal sensor may be used to determine the relative position of the device or part of the user's body.

Abstract: An improved device for monitoring respiration or other vital signs of a user using one or more sensors. The invention may be worn within the mouth of the user to allow more accurate, direct, and fast measurements. The invention may also include a distribution mechanism that may be used to administer a substance such as medication. The substance may be administered in response to data collected by one or more of the sensors in the device and/or in response to data received from another device.

Abstract: A device and method for collecting subject responses, particularly during magnetic imaging experiments and testing using a method such as functional MRI. The device comprises a non-metallic input device which is coupled via fiber optic cables to a computer or other data collection device. One or more optical switches transmit the subject's responses. The input device keeps the subject's fingers comfortably aligned with the switches by partially immobilizing the forearm, wrist, and/or hand of the subject. Also a robust nonmetallic switch, particularly for use with the input device and methods for optical switching.
