  • Patent number: 6606974
    Abstract: A fuel injection control system and method for delivering multiple fuel injections to a cylinder of an engine during a fuel injection event based upon engine operating conditions, the control system including an electronic controller coupled to an electronically controlled fuel injection device, and a plurality of sensors coupled to the controller for inputting certain signals representative of certain engine operating conditions of the engine, the controller being operable to output a fuel injection signal to the fuel injection device to deliver pilot, main, and anchor fuel shots to the cylinder during a fuel injection event based upon the sensor signals. The controller also divides the desired fuel quantity between the three shots. In dividing the total fuel set by the governor system between the three shots, the controller determines desired pilot and anchor fuel shot amounts and also determines minimum pilot, main, and anchor fuel shot amounts.

  • Patent number: 5941873
    Abstract: A surgical laser smoke plume evacuator includes an evacuator body which is formed to a shape which is suitable for placement in normal use position substantially entirely around and adjacent to a tissue site upon which laser surgery is to be performed. The evacuator body has structure for removing smoke therethrough, and a smoke exit portion in communication with and extending from the evacuator body. The smoke exit portion is connectable to vacuum source, to thereby apply a vacuum to the evacuator body and cause smoke which is created at a surgical site during surgery to be removed from the surgical site through the evacuator body and the smoke exit portion.
