Abstract: Embodiments of the invention provide for a joystick assembly that separates the user from electrical equipment. In some embodiments, the joystick assembly comprises a handle, a rod, a camera, and a target object. The target object may move indicative of the handle by input from the user. The camera may obtain a target object image of the target object and a difference between the target object image and the image pattern is determined. A signal indicative of the difference between the target object image and the image pattern may be sent to actuate at least one actuator.

Abstract: A load-indicative alarm system alerts an operator as to a load. The load-indicative alarm system includes a load-measuring device, a controller, and an alerting device. The load-measuring device for provides a load indication. The controller determines a load level by acquiring the first load indication from the load-measuring device. The alerting device is configured to alert the operator. The controller is configured to instruct the alerting device to alert the operator if the current load level is above a minimum threshold. The alerting device provides a load-indicative alert that informs the operator of the load level being above the minimum threshold.

Abstract: A method and apparatus for controlling a work tool. The method and apparatus includes receiving a command to engage a vibratory mode of the work tool, actuating the vibratory mode, and increasing at least one of an amplitude and a frequency of vibration as a function of time during receipt of the command.
