Abstract: Systems and methods of embodiments of the present disclosure provide automated testing of PPG sensors using a programmatically controlled rotational actuator. The rotational actuator may include one or more light reflecting surfaces that can be actuated towards and away from the PPG sensor to simulate reflectivity of the tissue of a subject. Particular heart rates, heart rate variabilities and/or other physiological behaviors may be simulated based on actuations patterns, including, e.g., frequency, range of actuation, or variations thereof, among other actuation pattern characteristics. Based on the output signal produced by the PPG sensor in response to the actuation pattern, the PPG sensor may be assessed for accuracy and/or sensitivity to ensure quality.

Abstract: Control systems and methods are provided that utilize a device, which can be worn by a user, to enable the user to enter control commands for causing a controller to control one or more electronic devices in a local network, such as a Wi-Fi system. A local control system, according to one implementation, includes a smart ring configured to obtain movement information related to one or more movements of the smart ring while a user is wearing the smart ring. The local control system also includes a controller device configured to communicate with the smart ring using Bluetooth or Wi-Fi signals. Characteristics of the movement information can be translated in order to obtain one or more control commands. The controller device is configured to control one or more aspects of one or more electronic devices based on the one or more control commands.

Abstract: Systems and methods of embodiments of the present disclosure provide automated testing of PPG sensors using a programmatically controlled light source. The light source may include one or more light emitting elements that can be modulated to emit light towards the PPG sensor to simulate reflectivity of the tissue of a subject. Particular heart rates, heart rate variabilities and/or other physiological behaviors may be simulated based on illumination patterns, including, e.g., frequency, range of intensity, or variations thereof, among other illumination pattern characteristics. Based on the output signal produced by the PPG sensor in response to the illumination pattern, the PPG sensor may be assessed for accuracy and/or sensitivity to ensure quality.
