Abstract: A bone plate comprises a plate body and at least one tab. The plate body defines an inner body surface configured to face an underlying bone, an outer body surface opposite the inner body surface, and an outer side surface that extends between the inner body surface and the outer body surface. The outer side surface defines an outer perimeter of the plate body. The at least one tab includes a head and an arm that extends from the plate body to the head. The tab defines a tab aperture that extends through the head and is configured to receive a bone anchor. The bone anchor can be coupled with a screw hole in the nail. The arm is configured to deflect with respect to the plate body so as to move the head between a pre-fixation position and a fixation position spaced from the pre-fixation position.

Abstract: A focusing system for a variable focus lens of a motion picture camera includes a pulse modulator and a microwave transmitter mounted on a camera frame for generating a high frequency pulsed signal which is transmitted to a selected target which carries a reactive signal generator that is responsive to the first signal for coding and retransmitting the coded signal back to a receiver mounted on the camera frame, and a signal processor for determining the interval of travel of the signal and translating the interval into a distance-analog signal that is transmitted to a focusing motor for driving the focusing mechanism of the lens for focusing the lens at the distance determined by the signal. One alternate embodiment includes multiple reactive signal generators having distinctive signal responsive controls and portable remote transmitters for selectively switching to the selected ones of said reactive generators.
