A mounting system for securing an electric machine to a surface is provided. The retainer ring allows a user to orient a suture about the instrument, such that a knot in the suture is automatically advanced and tightened by withdrawing the instrument from a surgical site after placing the suture. These elements are stacked on a substrate, and light is emitted to an exterior of the device via at least the cathode. This assembly is especially amenable to an automated assembly process because it allows easy alignment of the collimated lens assembly with optical components retained within the assembly, and adherence of the collimated lens assembly to the optically transmissive side thereafter. As one example, a method for controlling access to a magnetic storage medium is disclosed that includes providing a location count indicating a location between a portion of a first servo data sector of a magnetic storage media and a portion of a second servo data sector of the magnetic storage media, and asserting an enable window signal based upon the location count. The contoured portion defines an inter-relationship between a vector angle and a deep draw depth that achieve a satisfactory stretch factor.
