Abstract: A computer-implemented method for providing locating and exposure monitoring includes receiving data indicating a safety event and a first location from a first device and receiving a second location from a second device. The method includes transmitting an alert and the data indicating the safety event to the second device when the second location is within a predetermined distance from the first location, wherein the second device relays the alert and/or a gas reading to at least one peer device in a mesh network joined by the second device.

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.

Abstract: Disclosed is a tangible article of manufacture having instructions stored thereon that, when executed, cause a machine to perform operations for tracking an operator and operator status using a safety device. The operations include programming a plurality of NFC tags with assignment information, wherein the assignment information is at least one of a location assignment for NFC tags being placed at particular locations and an instrument operator assignment for NFC tags distributed to multi-gas detection instrument operators. The instructions further include receiving temporary assignment information at the safety device when an NFC radio of the safety device is brought in proximity to at least one of the plurality of NFC tags; and tagging safety device data with the temporary assignment information.

Abstract: A system including a plurality of network devices including one or more worker monitoring devices and one or more area monitoring devices is provided. The plurality of network devices monitor at least one of a peer alarm, a worker biometric datum or an area environmental datum. The plurality of network devices are structured to communicate with one another in an ad-hoc wireless mesh network. A first network device of the plurality of network devices transmits the at least one peer alarm, worker biometric datum or area environmental datum for presentation on a second network device of the plurality of network devices.

Abstract: A system including an instrument node and a wireless mesh network having an encryption key is provided. In response to receiving a scan mode message from the instrument node, the wireless mesh network is operative to transition into a scanning state wherein the wireless mesh network listens on a primary channel for a boPeep message from another wireless mesh network having the same encryption key. In response to receiving the boPeep message, the wireless mesh network generates and queues for receipt by the instrument node a network information message identifying one or more properties of the another wireless mesh network. In response to receiving the network information message, the instrument node joins the another wireless mesh network.

Abstract: A method of providing information about a leader node to a plurality of follower nodes in a wireless mesh communication network is provided. The method includes designating the leader node; designating the plurality of follower nodes; and designating one or more predetermined frequency ranges as a public channel. The method further includes from the leader node and during a plurality of network intervals having a predetermined length of time, transmitting a sync message at a beginning of each network interval to the plurality of follower nodes. The method further includes during each network interval in which a sync message is received by any one of the plurality of follower nodes, transmitting from any of the plurality of follower nodes receiving a sync message, on the public channel, a message advertising at least one property of the leader node after receipt of the sync message.
