Abstract: An air purifier for inside air. The air purifier includes a housing and a closure assembly. The closure assembly is slideably and selectively removable from the housing. The closure assembly includes a cage on which a filter can be mounted. One or more sensors can detect the location of the closure assembly relative to the housing.

Abstract: A portable sanitizing apparatus, such as a case, includes a first case portion arranged to receive an object to be sanitized, and a second case portion connected to the first case portion and including at least one UV light source configured to emit UV electromagnetic radiation. The second case portion includes an expansion member having a collapsed configuration and an expanded configuration. When the expansion member is in the expanded configuration, a distance between the second case portion and the first case portion is increased compared to when the expansion member is in the collapsed configuration, thereby increasing a distance from the at least one UV light source to the object to be sanitized.

Abstract: A cannulated compression screw is used as an orthopedic implant and has a threaded distal end with an insertion tip that includes at least one and preferably two, three or four flutes to allow the screw to be self-tapping. Optionally, the screw also includes one or more reverse cutting flutes proximal to the insertion tip. The distal threads are cancellous threads having a generally constant minor diameter and a generally constant major diameter and a generally constant thread pitch. An intermediate portion of the screw is non-threaded and the proximal end includes a compression wedge or taper that has at least one, and preferably two to five flutes that terminate before the top of the screw. The proximal end further includes a radiused bevel to the terminal surface that includes a hexagonal torque driving recess. The diameter of the non-threaded shaft section is constant distal from the compression wedge to the distal tip where it defines the minor diameter of the threaded portion.
