Abstract:
1. A method, comprising: receiving, at an interface portion defining an orifice, a force having a first component parallel to an axis and a second component perpendicular to the axis, the second component of the received force having a first direction, the orifice defining a plane, the axis being substantially perpendicular to the orifice plane wherein the received force is based on an object being disposed within the orifice of the interface portion, the object having a range of sizes corresponding to a range of longitudinal positions of the object disposed within the orifice of the interface portion; and applying, to the interface portion, a force having a component perpendicular to the axis in a second direction, substantially opposite from the first direction, in response to the received force, wherein the component of the applied force is a constant value independent of the longitudinal position of the object within the orifice of the interface portion.
