  • Patent number: 9651254
    Abstract: A method for measuring and controlling flame quality in real-time, the method comprising the steps of: acquiring a plurality of flame images in a first field of view; acquiring a plurality of flame images in a second field of view; processing the acquired plurality of flame images of said first and second fields of view to determine an overall flame quality parameter; and comparing the overall flame quality parameter to a tolerance range. In other aspects, a system for measuring and controlling flame quality in real-time and a non-transitory computer readable medium (CRM) storing instructions configured to cause a computing system to measure and control flame quality in real-time are provided.

  • Patent number: 9266542
    Abstract: A method for determining the configuration of a diesel powered system having at least one diesel-fueled power generating unit, the method including a step for determining a minimum power required from the diesel powered system in order to accomplish a specified mission, and a step for determining an operating condition of the diesel-fueled power generating unit such that the minimum power requirement is satisfied while yielding at least one of lower fuel consumption and lower emissions for the diesel powered system.

  • Patent number: 8494696
    Abstract: A method is provided including determining a first power level required from a diesel powered system. The first power level corresponds to a first proportion of a maximum power. The method also includes determining an emission output for a mission based on the first power level. The method further includes determining a second power level corresponding to a second proportion of the maximum power, wherein alternate use of the second power level and at least one of the first power level or a third power level results in a lower emission output for the mission, with the overall resulting power being proximate the minimum power required. The method also includes automatically controlling operation of the diesel powered system by using the second power level alternately with at least one of the first power level or the third power level.

  • Publication number: 20100205995
    Abstract: An ice making device may include an ice tray, a drive mechanism for moving the ice tray to a water-supply position and to an ice making position, two guide plates each of which is formed with a guide groove for guiding the ice tray to the water-supply position and to the ice making position, two engaging projections provided on the ice tray and each of which is engaged with the guide groove, and two cranks each of which is formed with a drive groove with which the engaging projection is engaged and is connected with the drive mechanism to be turned for moving the ice tray. The water-supply position is located at a position separated from the ice making position in a lateral direction, and the two engaging projections are provided on the ice tray so that their axial direction are substantially coincided with each other, and a gravity center position of the ice tray is located on a lower side of the two engaging projections.

  • Publication number: 20080125924
    Abstract: A method for operating a diesel powered system having at least one diesel-fueled power generating unit, the method including evaluating an operating characteristic of the diesel powered system, comparing the operating characteristic to a desired value to satisfy a mission objective, and adjusting the operating characteristic to correspond to the desired value with a closed-loop control system that operates on a feedback principle to satisfy a mission objective. A system and a computer software code are also disclosed for operating a diesel powered system having at least one diesel-fueled power generating unit.

  • Publication number: 20080082223
    Abstract: A method for minimizing emission output from a diesel powered system having at least one diesel-fueled power generating unit, the method including determining at least one power level required from the diesel powered system in order to accomplish a specified mission, determining an emission output based on the power level required, and using at least one other power level that results in a lower emission output wherein the overall resulting power is proximate the power required.

  • Publication number: 20070097584
    Abstract: A transient voltage surge suppressor (TVSS) device, suitable for commercial/industrial applications, incorporates diagnostic circuitry. The TVSS provides seven modes of protection for three phases of a typical electrical service. A surge panel can protect against large current transients. The large current-handling capability stems from passing a large amount of surge current from one layer of a multilayer printed circuit to another through the use of arrays of plated through holes.
