A control unit for a worker wearing personal protective equipment is presented. The control unit includes a PPE network creator that, when activated, creates a network. The control unit also includes a PPE device identifier configured to detect a first PPE associated with the worker and a second PPE associated with the worker. The first PPE has a first speaker and a first microphone. The second PPE has a second speaker and a second microphone. The control unit also comprises a PPE network joiner that facilitates the first and second PPE joining the network. The control unit also comprises a preferred configuration selector that automatically selects a preferred speaker for the worker and a preferred microphone for the worker. The preferred speaker is the first or second speaker. The preferred microphone is the first or second microphone. The control unit also comprises a network communication component that automatically communicates a first device parameter settings to the first PPE and a second device parameter settings to the second PPE. The first and second device parameter settings are based on the selected preferred speaker and microphone.

An intelligent motorcycle helmet system includes a helmet assembly and a first control module incorporated into the helmet assembly and communicatively coupled to a set of helmet-mounted lighting components. A haptic feedback module is incorporated into the helmet assembly. A second control module is configured to be removably mounted to a motorcycle. The first control module selectively activates the helmet-mounted lighting components to reflect the state of the left and right turn signals and the brake light of the motorcycle as determined via the second control module and the lighting state sensing module. The first control module selectively actuates the haptic feedback module during operation of the motorcycle in response to at least one event associated with the motorcycle.

The present invention discloses a safety device adapted to prevent workers from going into hazardous environment, such as underground using the faulty safety device. As a safety device, typically embodied as a cap lamp, must be charged prior to each use, the device is adapted to detect when the device is removed from the charger. The device starts to blink continuously when disconnected from the charger. An automated test procedure is completed on the device. The user may also complete a manual portion of the test procedure to make the device usable. When the test procedure is completed successfully, the lamp stops blinking. If the test procedure is not successful, the lamp continues blinking to effectively prevent user from using a faulty device.

A magnetic fastening device for releasably fastening a first unit and a second unit to each other. The first unit has a first unit abutment surface. The second unit having a second unit abutment surface. The first unit abutment surface and the second unit abutment surface are adapted for abutment against each other. The device includes at least one pair of magnets including first magnet allocated to the first abutment surface and a second magnet allocated to the second abutment surface. The first magnet and the second magnet exert an attractive force to each other. The first unit may be or include a communication device and the second unit is a helmet or a separate unit permanently fixed to a helmet.
