Abstract: Multimedia data elements may be captured in the form of image data, audio data, textual data, and the like. Universal time and date stamps are associated with the acquisition of the various data elements to create a contextual reference. The data elements and contextual references are stored in a storage area, such as a database. A relational database may allow convenient storage and retrieval of data elements based on user-entered contextual search elements. In one embodiment, data input devices may be miniaturized and wearable by one or more users. Data may be collected manually or automatically with each data element having universal data, such as time, date and position associated therewith. Multiple users may each have a database and permission may be granted to view other databases or to alter other databases to thereby exchange data elements. Data elements may be retrieved based on search elements, such as the contextual references.

Abstract: A treadmill (10) includes a frame (12) on which are rotatably mounted first and second transverse roller assemblies (14, 16). An endless belt (18) is trained about the roller assemblies. A deck (20) is disposed between an upper run of the belt and the frame. The deck is supported spaced from the frame by a plurality of cup-shaped elastomeric springs (22). The elastomeric springs reversibly deform upon downward deflection of the deck toward the frame. Each elastomeric spring (22) has a sidewall (50) tapering in thickness. The resistance to the downward travel of the deck provided by the elastomeric springs is proportional to the degree of deflection of the deck toward the frame.
