readings from the wearer 39 s forehead the cover or sweat band 34 is removable for cleaning purposes an alternative to directly incorporating the biometric sensors 32 into the suspension band assembly 14 and then using a cover or sweat band 34 to protect the sensors would be to include the biometric sensors 32 directly into an integrative band 46 is illustrated in fig4 the integrative band 46 represents one assembly unit that combines a conductive pad 40 and a sweat band 34 the biometric sensors 32 and potentially a haptic motor 48 for providing haptic feedback to the wearer are placed on the conductive pad 40 thereby ensuring that the biometric sensors 32 and haptic motor 48 are positioned correctly and are connected to the electronic circuitry of the hard hat 10 the conductive pad 40 is connected directly with the control unit 18 through a physical connector 29 that might use a plug and play connection mechanism the physical connector 29 will identify which biometric sensors 32 are on the suspension band assembly 14 and send that information directly to the control unit 18 the physical connector 29 ensures data and power transmission from the biometric sensors 32 and the haptic motor 48 to the central control unit 18 and.
