Abstract: Examples relate to analyzing hardware systems. In some examples, an interface is used to discover components and connectivity attributes of the components. System templates are then identified based on the components and the connectivity attributes. For each system template, a difference profile describing differences between the system template and the components is created.

Abstract: A buoyant safety paddle (11) for a kayak, a canoe or other small boat facilitates kayak deep-water self-rescue reentries and facilitates the movement of small boats over aqueous surfaces. Such buoyant paddle displaces significant volume while minimizing weight eliminating the need for post-capsize attached flotation. Each such buoyant paddle's volume is predetermined and distributed to retain paddling efficiency. Each such buoyant paddle has a handle (19) which extends from one blade (12) or between two blades, and is water tight, with a continuous strong rigid skin (41) and low density core (42). This construction provides a buoyant, minimal weight, stiff, high strength paddle which is economical to manufacture.
