Abstract: A method and a system for estimating the intended position of at least one target-inaccurate user inputs applied by a user to an input device are provided herein. The method may include the following steps: analyzing one or more points of contact applied to a an input device, to derive input parameters associated with the user inputs; applying a decision function to the derived input parameters, to estimate an intended position of the at least one target-inaccurate input of the user, wherein the decision function is tailored for the user and is further based on user parameters associated with the user; and overriding, at a level of the input device, the actual user inputs with the estimated intended position of the at least one target-inaccurate input of the user.

Abstract: A charge director injection system includes a charge director tank, a liquid toner tank, a charge director pump to pump charge director from the charge director tank into the liquid toner tank, and a control system configured to measure a change in charge density per amount of charge director injected into the liquid toner tank, and create a charge profile indicating a relationship between amount of charge director injected into the liquid toner and change in charge density of the liquid toner within the liquid toner tank.
