Abstract: A device includes a context engine and a notification engine. The context engine determines a context indicator relative to received input while the notification engine selects, based on the context indicator and the received input, at least one type of notification from different types of notifications. A wearable electronic arrangement selectively communicates, and senses for different types of single user response to, at least a portion of the received input via the selected type of notification. The context engine receives feedback regarding the sensible different types of single user response to at least partially determine the context indicator.

Abstract: An example apparatus includes a first pinion component comprising a first pinion and a first cylinder centered therein, the first cylinder extending from a first surface of the first pinion, the first pinion having a first via and a second via; a first electrical path extending from a second surface of the first pinion, through the first via to the first surface of the first pinion, and further to a first surface portion of the first cylinder; a second electrical path extending from the second surface of the first pinion, through the second via to the first surface of the first pinion, and further to a second surface portion of the first cylinder, wherein the second electrical path is electrically isolated from the first electrical path.
