A radial artery compression device configured to be secured to a wrist or other portion of a patient to provide adjustable and consistent compression pressure in the area of a radial artery access site or other physiological portion of a patient to achieve hemostasis either during or after a medical procedure such as a percutaneous coronary procedure. The radial artery compression device includes a rotatable member and a compression pad adapted such that rotation of the rotatable member does not affect the rotational orientation of the compression pad. According to one embodiment of the present invention, a single rotation of the rotatable member results in complete extension or retraction of the radial artery compression device. According to another embodiment of the present invention, the rotation of the rotatable member results in a compounding of the extension or retraction of the compression pad relative to the body of the radial artery compression device.

Exemplary systems and methods described herein can be used to secure a rail to a module or the rail to a support using a nut that can be inserted at a desired point of mounting. Another exemplary system describes a flashing to be inserted under a roof shingle, wherein the flashing is secured to a support for a rail or module. Yet another exemplary system describes a clamp that secures a rail or module and is adjustable along the length of a post. Spacers can be added to the post to extend the adjustment range of the clamp.

A clamping apparatus secures a photovoltaic module to a rail. The clamping apparatus includes a bolt extending between a first end and a second end of the bolt. The clamping apparatus includes a clamp defining a bolt opening into which the bolt is received and a support structure. The support structure positions the clamp at a first location on the bolt. The first location is a first distance from a top rail surface plane within which a top surface of the rail lies. The support structure is adjustable to position the clamp at a second location on the bolt. The second location is a second distance from the top rail surface plane. The first distance is different than the second distance. The support structure has a support structure thickness corresponding to a third distance that is less than the first distance and less than the second distance.

The invention is a new stabilized racking system for solar cell panels on a surface through a novel use of ballast weights and a wind optimized design. The system is further optimized to fit a range of sizes and thicknesses of modules through a combination of self adjusting end clamps, adjustable tilt legs, and unique wind screen design. The system can include an array of individual solar panel systems that are reinforced in both lateral directions to reduce the amount of ballast weight required.
