A laser transmitter assembly of the present invention is configured for placement within a firing chamber of a user firearm and to have minimal interference with a firearm extractor during charging of the firearm. In this regard, a Bluetooth system may be operable to determine whether a coexistent time division multiplexing communication system is receiving signals and to control the types of packets it transmits based on the determination. The system and method used in this present invention require an additive which when added to fluid, forms viscous fluid for splash retardation. A second layer of gate material is formed over the storage layer. The first redistribution layer is mounted on the second chip surface of the second chip and is configured to provide contact with a substrate.
