Abstract:

A sprinkler height adjustment mechanism is described that can be used to increase the height of a top cover and a top of the riser relative to the sprinkler body.

Abstract:

Apparatus, systems, and methods for a medical implant with improved durability and strength. An implant structure having a mesh, wherein struts of the mesh vary in width as a function of length, where one or more segments are defined by one or more corresponding equations that define strut width. Connecting elements may be optionally included and may further optionally vary in width and shape. Strut tapering functions may be one or more segments of piecewise linear equations. Implant mesh structures may be symmetric, asymmetric, or may vary in segments along the length and/or circumference of the mesh. The mesh may be of a self-expanding or balloon expandable material suitable for medical use.
