Abstract: A system for ultraviolet irradiation of objects and a method of using this system is disclosed. The system includes: an illuminating device positioned in a center section of an octagon shaped a base area and including one or more elongated light sources, each emitting ultraviolet light given by shortwave ultraviolet light (UV-C light) and extending in parallel to a normal on the base area; a set of rotatable mesh grids arranged around the base area such that the mesh grids surround the illuminating device and configured to be equipped with the objects; and a set of reflectors including a set of movable side reflectors, wherein the reflectors are configured to be arranged such, that they form a resonator surrounding the mesh grids surrounding the illuminating device.

Abstract: Computer systems, storage media encoded with software, and methods comprising a first processing device configured to generate and deliver an ad unit for at least one good or service offered at a physical retail outlet, the ad unit delivered to an application executing on a second processing device, the ad unit providing: a display of one or more outlets, the outlets offering the at least one good or service, the outlets located within a first threshold distance from the second processing device; directions from the location of the second processing device to a selected outlet; and at least one proximity-based offer, the offer triggered by presence of the second processing device within a second threshold distance from the selected outlet; provided that the display of one or more outlets, the directions, and the at least one proximity based-offer are provided within the application executing on the second processing device.
