Abstract
A static memory device including an instrument, a wireless radio, a shared memory, an outgoing memory portion and an incoming memory portion. The instrument includes an environmental sensing device, a hazard detection device, and/or an industrial safety device. The wireless radio sends and receives information on a wireless mesh network. The shared memory is connected to the instrument and wireless radio and includes static message memory having static messages related to the instrument. The outgoing memory portion receives outgoing information from the instrument and transmits the outgoing information to the wireless radio for transmission on the wireless mesh network. The incoming memory portion receives incoming information from the wireless radio and transmits the incoming information to the instrument. The shared memory restricts the wireless radio and the instrument from both raising grant lines and granting data to either the incoming memory portion or the outgoing memory portion simultaneously.
