A safety system for a user includes an article of personal protective equipment (PPE) configured to be at least partially in contact with the user. The safety system further includes at least one tactile actuator and a controller. The at least one tactile actuator is associated with the article of PPE. The at least one tactile actuator is configured to provide tactile stimulation to the user. The controller is communicably coupled to the at least one tactile actuator. The controller is configured to provide an actuating signal to the at least one tactile actuator to actuate the at least one tactile actuator based upon at least one predetermined condition. The at least one tactile actuator generates a tactile indication upon receiving the actuating signal.

Safety system, article of personal protective equipment, and method

A safety circuit for a Personal Alert Safety System (PASS) device includes a safety logic circuit and an alarm circuit. The safety logic circuit is communicably coupled to the PASS device. The safety logic circuit includes a timer configured to determine a time elapsed since the timer has been last reset. The safety logic circuit is configured to switch from an off state to an on state upon receiving an activation signal from the PASS device and reset the timer upon switching to the on state, generate a trigger signal in response to the timer exceeding a time threshold, and reset the timer upon receiving a reset signal from the PASS device before the timer exceeds the time threshold. The alarm circuit is communicably coupled to the safety logic circuit and configured to generate an alarm signal upon receiving the trigger signal from the safety logic circuit.

Safety circuit, device and method

A system for use with a personal protective equipment (PPE) article includes a memory configured to store a user identification associated with a user of the PPE article. The system further includes a safety module configured to selectively generate an alert signal based on a motion status of the user of the PPE article. The system further includes a transceiver unit configured to wirelessly transmit and receive data. The system further includes a controller communicably coupled to the memory, the safety module and the transceiver unit. The controller is configured to retrieve the user identification from the memory upon receiving the alert signal from the safety module. The controller is further configured to convert the user identification into a speech data. The controller is further configured to transmit the speech data through the transceiver unit.

System and method for personal protective equipment article

A monitoring unit for wireless communication with a plurality of self-contained breathing apparatus (SCBA) units configured to form a network is provided. The monitoring unit includes a communication interface and processing circuitry. The processing circuitry is configured to receive, via the communication interface, a plurality of updates from each of the SCBA units where each update includes information indicating at least one communication link quality to at least one other SCBA unit. The processing circuitry is further configured to determine at least one distance from each SCBA unit to at least one other SCBA unit that is one hop away in the network based at least in part on the communication link quality. The processing circuitry is further configured to cause the determined at least one distance to be displayed.
