ABSTRACT:
An inertial sensing device with a movable sensing element is provided with a conductive path for bleeding excess electric charge from the sensing element. The path may extend from the sensing element to a control circuit or other predetermined portion of the device and preferably includes an electrical component having a preselected impedance. In a specific embodiment, the electrical component is a block of semiconductive material and has a time constant smaller than the time constant associated with the build-up of charge on the sensing element.
