Systems and methods for platform occupancy detection on an aerial device are described. An aerial platform may be provided for the aerial device. A worker may perform operations in the aerial platform and connect to an interlock system thereof. The worker may have an associated transmitter configured to transmit a signal. A first receiver and a second receiver may be disposed on the aerial platform to receive the signal. Based on the time difference between receiving the signal at the first receiver and receiving the signal at the second receiver, the position of the transmitter may be triangulated. If the transmitter is determined to be within the aerial platform and the worker is not connected to the interlock system, preventive actions may be taken before operation of the aerial platform is permitted.

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.

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.
