Coinjection molding system control apparatus and method preferably includes flow control structure andor steps configured to reduce pressure on a second melt, preferably causing a relatively small portion of a first melt to flow from a distal portion of a first melt channel in the coinjection nozzle into a distal end of a second melt channel in the coinjection nozzle. In one embodiment, a method for extending alerts for a wireless device includes linking the wireless device through a wireless connection with a wireless ringer module; wherein the wireless ringer module is removably coupled to a device having an interface for receiving and coupling with the wireless ringer module. Optionally, the submucosa can be packaged in such a manner to permit sterility or maintain sterility of the submucosa. The server then generates updated time-offset values, based on a method of least squares, in which each residual is a difference between the reference and predicted coordinates of each wireless terminal location, for one or more wireless terminals. The disclosure further provides a pouch including a first sealed compartment containing a first composition, the first sealed compartment comprising the water-soluble film according to the disclosure.
