Abstract: A method and apparatus for transferring high data rate data between a pair of separated high data rate buses comprising storing a group of high data rate data from one of the buses, one of which is connected to a digital telephone set, reading the stored data at a low data rate, conditioning the low data rate data to remove high frequency components therefrom, applying the conditioned data to an unshielded cable for transmission to the separated other high data rate bus, receiving and storing the conditioned data from the unshielded cable and reading the stored conditioned data at a high data rate to said other bus.

Abstract: A method for applying therapeutic heat by a therapeutic heating pad which is not hot to the touch provides substantial infrared radiation to a user. Accordingly it can be used for extended periods without feeling uncomfortable to the skin, while imparting deep therapeutic heat to the user. The heating pad is comprised of a radiant heat generating layer having a plane surface comprising means for radiating heat evenly from its surface, a pair of flexible electrically insulating and radiation permeable layers located adjacent and covering opposite sides of the layer, a thermal insulation layer disposed against and covering one of the electrically insulating layers, a radiation reflective layer disposed against and covering the outside surface of the thermal insulation layer, and a sealed radiation permeable envelope enclosing the entire heater.
