  • Patent number: 10312065
    Abstract: A method, apparatus and system for controlling the processing of a substrate within a process chamber are described herein. In some embodiments, a method of controlling a substrate process within a process chamber includes determining a position of a moveable magnetron in the process chamber relative to a reference location on a surface of the substrate and modulating a power parameter of at least one power supply affecting substrate processing based on the determined position of the magnetron to control, for example, at least one of a deposition rate or an etching rate of the substrate processing. In one embodiment, the modulated power parameter is a power set point of at least one of a direct current (DC) source power, a radio frequency (RF) bias power, a DC shield bias voltage, or an electromagnetic coil current of the at least one power supply.

  • Publication number: 20110113689
    Abstract: A voltage is supplied at an output of a switched mode power supply to a component of the movable barrier operator system. A change in a current being supplied to the component of the movable barrier operator system is sensed by the current sensing circuit. A change in the voltage being supplied at the output of the switched mode power supply is responsively effectuated based at least in part upon the change in the current sensed by the current sensing circuit.

  • Patent number: 6900724
    Abstract: A virtual electronic back-up alignment apparatus that consists of a housing that provides a means for fixedly securing a light emitting source parallel to a vehicle and a means for activating the light emitting source and generating a light beam. A free rotating mirror assembly receives the light beam from the light emitting source and reflects the light beam into a directional guideline towards the trailer forming a virtual tow point for enabling the user to obtain the perfect alignment of the vehicle hitch to the trailer tow hitch. The free rotating mirror assembly comprises an orientation balancer, a mirror, and a pair of wheels encapsulated within a hollow, transparent tube secured to the housing for maintaining a parallel orientation between the light emitting source and the alignment point on the trailer.

  • Patent number: 5717609
    Abstract: Disclosed is an energy measurement and verification system and method which provides real time documentation of both baseline and post-retrofit energy consumption. Actual energy savings are calculated with a unique combination of computer hardware, energy and data translation software, measurement protocols, and digital remote sensing equipment which monitor the energy consumption of the retrofit environment and a sample baseline environment.

  • Patent number: 4810917
    Abstract: The method of forming a compact resolver/encoder assembly which is impervious to moisture, comprises several steps. First a number of electronic components of the resolver/encoder are mounted on a flexible printed circuit board. The circuit board is then folded into a generally cylindrical envelope and placed in a generally cylindrical container having a closed bottom end and an upper open end. The folded circuit board tens to unfold against the inner surface of the cylindrical wall of said container. Then a form made of stiff but flexible paperboard is inserted within the cylindrical envelope and tends to unfold to take on a tear drop cross section. Next a heat insulating potting compound is inserted into the generally annular space in the container between the form and the cylindrical wall of the container where the folded, printed circuit board is located.

  • Patent number: 4728834
    Abstract: The compact digital resolver/encoder assembly comprises a resolver and a flexible printed circuit board having a number of electronic components for decoding the resolver mounted on the flexible printed circuit board. A generally cylindrical container is provided having a cylindrical wall, a closed end and an open end. The circuit board is folded into a generally cylindrical shape and received in the container separate from the resolver. The circuit board is insulated from the container by an electrical insulating potting compound situated in the container and surrounding the circuit board. The resolver is received in the container and is spaced a predetermined distance from the encapsulated circuit board. Preferably a voltage regulator is mounted to an inside wall of the container and electrically coupled to the circuit board.

  • Patent number: 4389969
    Abstract: A means for detecting the application of glue to a defined area of a moving box blank includes a capacitance device, one plate of which is formed by a sensing surface positioned adjacent the path of box blank movement, with the other plate being formed by the defined area of the box blank and the applied glue. There are means for applying an electric signal to the sensing surface and means for sensing variations in said signal caused by the presence or absence of glue. There is a control circuit for enabling the detector, which control circuit enables the detector after a glue application and after a period of delay consistent with movement of the box blank from the glue applicator to the detector.

  • Patent number: 4369080
    Abstract: A means for sensing the amount of a liquid bonding agent applied to secure a corrugated medium to a liner includes a capacitance device, one plate of which is formed by a sensing surface positioned adjacent the corrugated medium, liner and the applied liquid bonding agent. The other plate of the capacitance device is formed by the moving corrugated medium, liner and the applied bonding agent. There are means for applying an electric signal to the sensing surface and means for sensing variations in that signal caused by the amount of the liquid bonding agent applied to the corrugated medium and liner. The sensed variations in the applied electric signal are used to control the application of the bonding agent to the corrugated medium. The capacitance device may include a plurality of individual sensing areas having a width and spacing related to the width and spacing of the tips of the corrugated medium.
