Abstract: The present invention related to a system to remove snow and ice from a surface. The system transports hot steam from pre-existing underground steam pipes or the steam producing devices directly onto the grate on the surface.

Abstract: An illuminated walking cane including a handle, a pole, and a rubber tab on the distal end of the pole. The handle includes a compartment for at least one battery connected through an electric circuit to a plurality of luminous sources. The luminous sources are placed in different heights on the inside of the cane. The cane also contains a series of tubular extended pieces that enlarge and shorten by fitting one into the other, in telescopic action. An automatic trigger mechanism allows the cane to be both retractile and protractile.

Abstract: A system for clearing snow, ice, or frost from pavement and similar surfaces. The system is located underground and combines at least one main pipe of gaseous steam flow network including multiple independent pipe branches with valve devices, spaced apart from one another, all of which converge at least one secondary pipe including a series of sprinklers having snow or ice detection sensors, as well as an automatic trigger device for triggering the sprinklers, so as to melt the snow or ice formation.
