Abstract: A method for motion-tolerant optical heart-rate monitoring may include calibrating an array of heart rate sensors of a handheld device by (i) evaluating, while the handheld device is being held by a user, an output of each sensor in the sensor array, (ii) selecting, based on the evaluation of the output of each sensor, a subset of sensors in the sensor array for use in detecting a heart rate of a user, and (iii) using the subset of sensors to monitor the heart rate of the user. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A device including an antenna, a printed circuit board having a side-plated contact, and an antenna carrier that includes an integrated spring having a conductive surface, such that the conductive surface is communicatively coupled to the side-plated contact can be used in optical systems. Disclosed computer-implemented systems and methods may include a dark source that when applied as part of an augmented reality projector, can temporarily reduce the photosensitivity of a user's eyes. Furthermore, a method for forming a lens block over a substrate and hardening the lens block and a method for motion-tolerant optical heart-rate monitoring can be disclosed herein for optical systems.
