This document describes techniques and apparatuses for implementing an object-detecting backlight unit for a display device. The method includes relieving wall stress on a diseased heart by an amount to decrease a rate of myocardial cell loss. A virtual mass of each parsed object is calculated, in order to define a shape of multiple context-based conformed dimensional data gravity wells that are created when data objects that are pulled into each of the context-based conformed dimensional data gravity well frameworks on a context-based conformed dimensional gravity wells membrane. It is determined whether the message should be forwarded to the control device. An engagement portion with at least one generally conical outer surface extends circumferentially about and faces generally away from the valve axis. In the holder, an optional circular opening with a spherical cross-section allows the probe to be rotated into position, and X-Y-Z positioning too may be provided, all manually or by motor.
