A radio telephone that automatically terminates an incoming call to a voice mail comprising a transceiver for receiving the incoming call, and a sensor coupled to the transceiver producing a set of parameters related to a user in close proximity to the radio telephone. When a station is inactive, a delivery flag is set when the station subsequently registers the over-the-air transmission is performed. The present invention further provides seals that facilitate attachment of flexible covering materials to hard surfaces. The first plurality of components is in electrical communication with the electrical contacts. The sidewall panel may also be included in an assembled barrel cooler. A conductive wire, such as a metal wire, is formed, based on a notching phenomenon which occurs when the etching selectivity between a polycrystalline silicon layer and a lower film is approximately 5 to 500:1.
