A polyaxial pedicle screw includes a housing, a bone screw member, and an anvil. The bone screw member includes a head and a threaded shaft extending from the head. The head is selectively securable within the housing. The anvil is positionable within the housing adjacent to the head of the bone screw member when the anvil and the head of the bone screw member are positioned within the housing. The anvil may define one or more grooves in an outer surface of the anvil. The groove defines a flap that is flexibly attached to the anvil to enable the anvil to flex an amount sufficient to maintain the head of the bone screw in constant contact with the anvil when the bone screw member is moved relative to the anvil.

A controller is provided for maneuvering an interrogation plane relative to a reference surface. The interrogation plane intersects the reference surface and is associated with a pole about which the interrogation plane is rotatable. The pole has an adjustable angle of inclination relative to the reference surface. The controller has a base, a handle, and an arm extending from a connection with the base to a connection with the handle. The arm has hingable joints which hinge to allow the handle to be translated relative to the base in arbitrary directions across a user surface. The controller further has position sensors which measure the translation of the handle relative to the base on the user surface. The translation provides a corresponding translation of the interrogation plane relative to the reference surface. The handle is rotatable about a rotation axis and is tillable about a tilt axis to allow the handle to be angularly moved relative to the user surface. The controller further has angle sensors which respectively detect the rotation about the rotation axis and the tilt about the tilt axis. The rotation about the rotation axis and the tilting about the tilt axis provide angular movement of the interrogation plane relative to the reference surface corresponding to the angular movement of the handle relative to the user surface.

The invention discloses a liquid crystal display device, which performs high quality display with less display nonuniformity, excellent view angle characteristics and transmissivity, with high production efficiency. The liquid crystal display device is provided with a first substrate having a pixel electrode and an orientation film, a second substrate having a common electrode, and a liquid crystal layer arranged between the first substrate and the second substrate. The pixel electrode includes a plurality of subpixel electrodes which are electrically separated from each other on an insulating layer. The subpixel electrode has a recessed section which is recessed to the side of the insulating layer. The subpixel electrode and a drain line are connected at the recessed section, and the common electrode is formed substantially flat over the entire pixel electrode.
