Abstract: An assembly comprises a retractor having a first face, a second face, and a body. The first face being spaced from the second face on an axis. The body extending between the first face and the second face along the axis. A clip that is supported on the second face. A handle that has a stowed position. The handle in the stowed position is adjacent the body. The handle is retractably connected to the retractor.

Abstract: A system including a transmitter and a receiver. The transmitter has a human machine interface and a plurality of magnets. The receiver has a noise generator and a vibration motor. The receiver has a first state and a second state. The receiver includes a proximity sensor. The receiver is configured to change from the first state to the second state in response to detection of a magnetic field by the proximity sensor. The transmitter is pairable with the receiver when the receiver is in the second state. The noise generator and the vibration motor are each operable by the human machine interface when the transmitter and the receiver are paired. The transmitter is magnetically couplable to a user device by the plurality of magnets.
