A method and a computer program product embodying software for measuring the utilization of all components in an end-to-end application and automatically associating them with the end-user and end-user activity. Other aspects of the invention relate to a method of making the mechanical to electrical conversion, and to a lockable actuator for operating an electrical switch connected to the actuator. In one embodiment, the invention relates to a tire rubber tread splice. A support shoulder, rim, or plurality of support shoulders on the outside of the fill funnel form a stable plane atop the tube rim. Alternatively, the polymers and cells can be mixed and then injected into the in vivo site and crosslinked in situ for organ, tissue, or bone repair or replacement.
