Abstract: A boat docket bumper assembly designed to be clamped to a boat dock to protect a boat from coming in direct contact with the dock. The boat dock bumper assembly includes a vertical support to one side of which a bumper can be attached. The assembly has a mounting member that when combined with suitable clamps, provides for attachment of the assembly to the edge of a dock regardless of its height. The vertical support may include a plurality of holes which provide for adjustability of the height of the bumper or it may include slots with adjustable tie bars to which the bumper can be attached.

Abstract: A video processing apparatus receives an analog color composite video signal, which has a color burst and generates a D2 digital signal sampled at a certain phase relationship with the color burst by a sampling clock. The analog video signal is phase shifted to produce a "zero" video signal. The analog video signal and the phase shifted video signal are added together to produce a sum video signal. The sum video signal is clocked into a latch by the sampling clock signal. The output of the latch is delayed by two clock pulses to produce a delay clocked video signal. The delay clocked video signal is compared with the output of the latch to produce a comparing signal. The comparing signal is used to adjust the phase of the sampling clock signal to automatically control the phase relationship between the analog video signal and the sampled digital signal.
