Abstract: Apparatus and a method for applying current of a particular form to bulk resistance means such a living tissue. The applied current is D.C. at a level so low as to generate voltage gradients within the bulk resistance such as to be substantially under nerve or muscle stimulation potential. Apparatus is provided to increase the current level at a first predetermined rate to a first level for a first period of time, to lower it to a second level for a longer period of time, then to lower it to zero at a second predetermined rate. When applied to painful living tissue substantial reduction or elimination of pain and inflamation has been found to occur.

Abstract: This invention relates to a multi-point information distribution system useful for telephone service, data connecting systems and other applications which permits a central station to service a plurality of outlying stations, through transmission media such as radio waves or wire cables, in privacy and using only one transmitting medium such as a first transmitting carrier frequency and one separate receiving medium such as a different receiving carrier frequency. The transmission media couples selected input connection points to selected terminating circuit devices one at a time. In accordance with the invention, the content on input connecting ports from a community dial office or other central system is time sampled at the central station which then transmits a sequentially ordered sample stream. Each terminating circuit or device is adapted to receive the content of only one time slot, and to transmit only during a coordinated and synchronized time slot.
