A pressure and vibration sensing apparatus designed to sense pressure together with vibration through one apparatus. The fuze includes a fuze housing having an outer surface, a flange extending radially from the outer surface of the fuze housing, and an acceleration sensor connected to the flange. The synchronization commands can be received by a mobile communication device and then forwarded to the participant computer system where it is used to synchronize the copy of the presentation data with the presenterserver. To allow the display assembly to fit closer to the edges of the housing, material can be removed from the flat support chassis.
