Abstract: This document describes systems and techniques to avoid and manage poor wireless connections on mobile devices. The described systems and techniques can determine, based on a determined signal quality or signal strength of a current wireless connection, that a superior signal quality or a superior signal strength is available at a location adjacent to, or within a determined distance of, a current location of the mobile device. In response to determining that the superior signal quality or the superior signal strength is available at the location, the mobile device can provide an alert to a user. The alert can indicate the location adjacent to, or within the determined distance of, the mobile device. In this way, the described systems and techniques can direct users to better network connections or alleviate their impact.

Abstract: A capacitive sensing system is adapted for noninvasive measurement of blood pulse (hear rate). A capacitive sensor is located near a skin pulse point exhibiting pulse displacement of skin tissue from vascular pulsation (for example, the temple area of the head), and includes a sensor electrode disposed over and spaced from the skin pulse point, such that the distance between sensor electrode and the skin pulse point cycles between a proximal and a distal displacement distance based on vascular pulsation.
