An input device is provided with improved electrostatic discharge protection. Radiating elements disposed along outlying center lines are movable and provided with compensating radio frequency feed line phase shifters so as to provide broad range of beam width angle variation of the antenna array’s azimuth radiation pattern. Movement can include rotational movement of the end effector about an axis of the shaft, articulation of the end effector relative to the shaft, and actuation of an end effector, e. Methods of synthesis and of use of the compounds are also disclosed. The novel compositions release the agent following administration for a time period ranging from about 2 to about 24 hours or longer. Generally, an econometric engine for receiving sales data, cleaning the data and generating imputed variables is combined with a financial engine for receiving imputed variables from the econometric engine, receiving cost data, generating a cost model, and outputting the cost model to the optimization engine.
