A system and method for providing an emergency contact party telephone line in response to an emergency. In the present invention, a spacer is formed over a pixel electrode, thereby protecting the pixel electrode layer from a mask in formation of an electroluminescent layer. At least one cavity is disposed in the strip-shaped plate. The return guide includes at least one supported portion. Thus, points in different segments may be logged at different rates. Simple removal of an interlock allows a disk, or Belleville spring assembly to apply an essentially even and constant pressure to the contents of the fluid reservoir assembly, and allows the device to then be attached to a skin surface via an adhesive contact surface.
