A method for transmitting radio signals and a receiver for receiving radio signals are described which are used to present a radio station which is transmitted on multiple frequencies with the data on the frequency that has the best signal quality. The device type information includes selection between at least one fast-but-leaky type and at least one slow-but-not-leaky type. The forward face of the shank region may project outward from the forward face of the lower portion. Such a teat cup can be integrated into a milking system having a valve manifold coupled to a number of teat cups and controlling flow of milk from the number of teat cups and flow of fluid to the applicators, and a controller including logic configured to provide control signals to the valve manifold. For a given portion, the junction of the non-threaded sections forms a lip by which to prevent the molded material from flowing into the threaded sections.
