Example techniques are provided for controlling volume of A / V devices using an improved volume control. The volume control may be implemented as a slider, where the sliding element is temporarily slid in response to user input (e.g., touched and dragged by the user), but then automatically “snaps” back to the center of the slider's range when the user input ends (e.g., is released by the user). Movement of the element from the center is interpreted as a relative volume adjustment, with the rate of volume change being proportional to the distance between the center of the range and the temporary position of the element. An indicator is provided indicating the rate, to provide user feedback. The volume control may be utilized as a master volume control in a home automation system.

An event tracking system tracks customer interactions to obtain product information that are made across plural contact mediums and displays an intuitive directed graph for analysis of the customer interactions. Each customer interaction is logged at each contact medium with a labeled reference associated with the content of the interaction, a time stamp and an identifier for the product or product user. An event modeling engine analyzes the log to identify contact sessions as contacts by the same identifier within a predetermined time so that an event tracking graphical user interface module prepares each contact session for display as a path of nodes interconnected by edges. Selected directed graph characteristics are highlighted, such as transitions from one contact medium to another or contact session volumes associated with an edge that have a relative volume compared with other contact sessions.

A cushion for a distal cup of a prosthetic socket has a total volume that includes a solid thermoplastic composition volume and a void volume. A ratio of the solid composition relative volume to the total volume yields a relative thermoplastic elastomer fill volume that is correlated with an elastic modulus of the cushion.
