An electroadhesive gripping device or system includes a plurality of electroadhesive gripping surfaces, each having electrode and each configured to be placed against respective surface regions of a foreign object, such that one or more electroadhesive forces can be provided between the electroadhesive gripping surfaces and the foreign object. A marking body, such as one having lead or a colored material, extends from the first end and is seated in the bore, while a connector is coupled to the second end. The driven pulley is designed so that a portion of the second sheave can enter inside the first sheave. These inputs propagate toward one another within a sequence of bit circuits. The hematocrit scaling factor is substantially about 1. In response to an execution activation motion performed upon any one button of the plurality of buttons, the function associated with that one button is executed.
