Abstract: Ultraviolet light disinfection systems expose medical devices, surfaces, patients and healthcare clinicians to UV light having wavelengths consist with killing microorganisms. UV light systems may use logic to govern the operation of UV light sources so as to apply a disinfecting dose of the UV light. UV detectors measure UV light exposure. Enclosures contain medical devices and flood the medical devices with the UV light. Some enclosures accommodate a person. Some UV systems project UV light onto high-touch surfaces of a healthcare environment. Some systems may be deployed within a patient transport vehicle. Some UV systems may be incorporated into medical devices.

Abstract: An apparatus for laying and burying wire underground having a cutter unit, a tow bar affixed to the front of the cutter unit and a drag plate affixed to the rear of the cutter unit. The cutter unit includes a blade which cuts a slit in the ground into which the wire is layed as the cutter unit is moved over the ground. The drag plate contains a weight and is utilized to repack earth over the slit made by the cutter unit thereby completely burying the wire underground. Motive power for the wire laying/burying apparatus is provided by any suitable vehicle to which the tow bar is attached.
