Abstract: A handheld light assembly for eradicating pathogens includes a housing. A processor and a lamp are disposed inside the housing. The lamp irradiates surfaces with disinfecting ultraviolet light having a peak wavelength of 222 nm filtered to restrict illumination to between 200 nm and 230 nm within an irradiation zone. A distance measuring system includes a secondary light source generating secondary light and a photodetector for measuring distance of the secondary light to a surface being irradiated by the lamp light being reflected from the surface to the photodetector. The secondary light source is offset at an angle from the lamp thereby projecting the light beam to a central area of the irradiation zone generated by the lamp. The photodetector signals the processor to calculate a vertical distance between the lamp and the central area of the irradiation zone on the surface being irradiated from an angular projection of the secondary light.

Abstract: New mobility components are provided that can enable a vehicle to traverse difficult terrain. In a particular aspect, vehicle leg components are provided that utilize unique degrees of freedom that can facilitate mobility. In a further aspect, vehicles are provided that contain such components.

Abstract: Stilts such as for use by a worker at a work site. Each stilt comprises a leg support, a shoe platform, a floor platform, a riser disposed between the shoe platform and the floor platform, and side supports, wherein each side support is connected to the leg support, the shoe platform, and the riser, wherein the stilt provides rigidity to the shoe platform without having to employ springs. Preferably, the riser is easily removable such that a different size riser can be used if a different level of elevation is desired, i.e., given the user's height and the height of the work to be performed. As such, the stilts are easily adjustable with regard to height. Additionally, preferably at least one or more other components of the stilts, such as the floor platform, is easily replaceable as well.
