A control circuit 70 is positioned in the control housing 62, the control circuit 70 is electrically coupled to each of the motion sensors 60 and the control circuit 70 receives a lower input and a lift input. The control circuit 70 receives the lower input when the motion sensors 60 sense motion. Additionally, the control circuit 70 receives the lift input when the motion sensors 60 do not sense motion for a pre-determined duration of time. The pre-determined duration of time may range between approximately 5.0 seconds and 10.0 seconds. The control circuit 70 is electrically coupled to the motor 36 associated with each of the actuators 20. The control circuit 70 actuates the motor 36 associated with each of the actuators 20 to rotate in the first direction when the control circuit 70 receives the lower input. Conversely, the control circuit 70 actuates the motor 36 in each of the actuators 20 to rotate in the second direction when the control circuit 70 receives the lift input.
A plurality of conductors 72 is each is integrated into the band 12 and each of the conductors 72 is comprised of an electrically conductive material. Moreover, each of the conductors 72 is electrically coupled between the control circuit 70 and a respective one of the motor 36 associated with each of the actuators 20 and a respective one of the motion sensors 60. A power switch 74 is slidably integrated into the control housing 62, the power switch 74 is electrically coupled to the control circuit 70 and the power switch 74 turns the control circuit 70 on and off. A power supply 76 is positioned in the control housing 62, the power supply 76 is electrically coupled to the control circuit 70 and the power supply 76 comprises at least one battery.
In use, the band 12 is worn around the user's head 14 and the power switch 74 is manipulated to turn on the control circuit 70. The face shield 40 is raised when the motion sensors 60 do not sense motion in front of the user. Conversely, the face shield 40 is lowered when the motion sensors 60 do sense motion in front of the user. In this way the face shield 40 can serve to inhibit airborne transmission of infectious diseases between the user and the person 44 that approaches the user. Moreover, the user does not have to remember 52 to lower the face shield 40 for adhering to mask mandates associated with a global pandemic or the like. The user can enjoy the freedom of breathing freely when the motion sensors 60 do not sense motion in front of the user.
