Abstract: A method of treating a person for stuttering that comprises providing sensory stimulation that alternates between the right and left side of person's body. In one preferred embodiment this stimulation is performed by applying a stream of sound pulses, alternating between the ears, by an auditory stimulation device. Such a device would include a sound signal production unit and a pair of auditory ear-pieces designed so as to not entirely occlude the ear canals.

Abstract: An ice rink surface building and resurfacing device has a water tank (175) mounted on a chassis (100), wherein the water tank is adapted to receive snow to be melted; a heating mechanism (107) mounted in heat exchange relation to the water tank; and a fluid disperser (290) connected to the tank for distributing a layer of water onto an ice rink surface. This device is well suited for ice rinks with various forms of ice surfaces in residential areas, in backyards, on remote terrain, and in community parks.
