Abstract: An air purifier may include a filter chamber having a recessed panel. The recessed panel may include openings, a plurality of UV lighting elements, and a plurality of reflectors disposed on, above, below, and/or within the recessed panel to provide a more even distribution of radiation across a surface of a filter. In some embodiments the plurality of reflectors may take the shape of a hyperbolic cone. The plurality of reflectors may be disposed above and/or adjacent to the plurality of UV lighting elements. The plurality of UV lighting elements may be disposed below or within the recessed panel. The plurality of UV lighting elements may include lighting elements which emit Ultraviolet (UV) and/or Ultraviolet C (UVC) wavelength light, such as certain light emitting diodes (LED) light sources to irradiate a surface of the filter.

Abstract: A desktop stapler includes a base portion and a lever assembly pivotally coupled to the base portion at a pivot point. A gap is defined between the base portion and a distal end of the lever assembly opposite the pivot point. A biasing member is coupled to the lever assembly and biases the lever assembly away from the base portion. A first solenoid is operable to move the lever assembly relative to the base portion to decrease the gap. A second solenoid is operable to drive a staple from the lever assembly. A controller is programmed to sequentially actuate the first solenoid and the second solenoid.
