SYSTEMS AND METHODS OF REMOTELY CONTROLLING A MATERIALS HANDLING VEHICLE
First Claim
1. A remote control device capable of wirelessly transmitting a travel request signal to a materials handling vehicle comprising:
- a support structure adapted to be mounted on a wrist or arm of an operator;
a wireless transmitter associated with said support structure; and
control structure in communication with said wireless transmitter, said control structure adapted to be actuated by the operator so as to cause said wireless transmitter to generate a first type signal to the materials handling vehicle.

Abstract
A supplemental control system for a materials handling vehicle comprises a wearable control device, and a corresponding receiver on the materials handling vehicle. The wearable control device is donned by an operator interacting with the materials handling vehicle, and comprises a wireless transmitter to be worn on the wrist of the operator and a travel control communicably coupled to the wireless transmitter. Actuation of the travel control causes the wireless transmitter to transmit a first type signal designating a request to the vehicle. The receiver is supported by the vehicle for receiving transmissions from the wireless transmitter.
