Positive positioning device and system

A positive positioning system, comprising:

• at least a first arm segment pivotably connected at a proximal end to a first pivot;
• at least a second arm segment coupled directly or indirectly to the first arm segment at a second pivot;
• a first positive positioning device located at the first pivot, and a second positive positioning device located at the second pivot, wherein the first and second positive positioning devices are set to normally resist rotation of the first and second pivots, respectively;
• at least one vertical plane pivot located distally of at least one of the first and the second pivot, wherein the vertical plane pivot is configured to allow rotation in a vertical plane and comprises a brake;
• and
• a user handle positioned distally of the second pivot, the user handle being configured to trigger release of the first and second positive positioning devices and the brake upon detecting contact between a user's hand on the user handle via capacitive sensing for a pre-determined time period to allow the user to reposition at least one of the first and second arm segments.

• a vertical plane pivot configured to allow rotation in a vertical plane, the vertical plane pivot comprising a brake;
• a user-actuated control device interconnected with the first and second positive positioning devices and the brake in a control circuit, wherein the user-actuated control device is actuatable to release the first and second positive positioning devices and the brake concurrently to allow a user to reposition at least one of the first and second arm segments.
