Abstract: A clock distribution and control system (10) includes one counter (30) in a clock generation domain and another counter (40) in a phase-delayed clock domain. The phase-delayed domain counter (40) output is combined with a programmable offset value chosen based on the phase delay of the clock distribution system. The result is used to insure that communication between logic in the clock generation clock domain and logic in the phase-delayed clock domain occurs deterministically on the correct clock edge for a range of clock frequencies.

Abstract: An adjustable logic circuit includes a pulse filter and delay circuit, a state machine and combinational logic circuit, and a data strobe generation circuit. The pulse filter and delay circuit is operative to read an adjustable configuration value and, based thereon, to implement a delay between an internal clock and both a data signal and a data strobe signal, the delay being a fraction of a clock period. The state machine and combinational logic circuit are operative to select a data value from a plurality of data values, and to provide a data signal based upon the data value. The data strobe generation circuit is operative to provide the data strobe signal at a time when both the data signal is valid and the delay is compatible with a predetermined external device.

Abstract: A method of repairing windshields that have been chipped or cracked comprising the steps of removing damaged glass from a break in the surface of the glass, fixing a pressure applier over the break, impact vibrating the windshield and heating the reverse side of the windshield to increase the size of the opening being filled and to drive air from the opening, injecting a resin into the damaged area while vibrating and heating and, if necessary, removing any additional air by developing a suction over the damaged area. The apparatus of the invention includes a frame that is suction held in place, and that mounts the injection plunger and a vibrator to vibrate the glass as a resin is injected into openings in the glass.
