  • Patent number: 9242727
    Abstract: Embodiments of the inventive concepts disclosed herein may provide visual and audible flight direction cues to the pilot of a helicopter to maintain an optimum energy sustaining profile to successfully perform an autorotation maneuver. From the moment the engine fails or fails to provide adequate power to the main rotor system, systems described herein provide airspeed, attitude, and altitude guidance to the pilot to intercept and fly the correct path for a successful autorotation entry and autorotation descent. The system displays specific cues as the helicopter approaches the determined flare altitude and guides the pilot through the autorotation flare and minimum rate of descent touchdown.

  • Patent number: 9138982
    Abstract: A method and systems to control the temperature of a Keyless inker for variable data lithography printing. Inker heating elements are adjustable to control ink feed to individual zones located across the width of an ink roller. Feedforward and feedback control loops adjust the ink supply dynamically based on a pixel count of the image content. The pixel count looks ahead in the video stream to allow time for the adjustment at the inker heating elements to propagate through the inker unit to affect ink output onto the imaging drum surface. Feedback of the achieved ink density on control patches on the imaging drum is also used to command the inker heating elements. Feedback is also used to update the inker propagation delay and dynamic model used to determine how much the inker keys need to be adjusted based on the pixel count stream.

  • Patent number: 8508791
    Abstract: A power saving apparatus and method for imaging modules in a variable data lithography system is provided. The imaging modules are arranged adjacent to each other to project a scan line of imaging data on a rotating imaging member in a variable data lithography system. The imaging module includes a look ahead buffer which stores imaging data and from which the stored data is read out for projection on the imaging member. The power saving apparatus uses an image look ahead concept to save part of the power consumed in the imaging modules in the projection mode of operation by selectively powering each laser source based on the imaging data in the look ahead buffer.

The ink keys are adjustable to control ink feed to individual zones located across the width of an ink roller. Feedforward and feedback control loops adjust the ink supply dynamically based on a pixel count of the image content. The pixel count looks ahead in the video stream to allow time for the adjustment at the inker keys to propagate through the ink train to affect ink output onto the imaging drum. Feedback of the achieved ink density on control patches on the imaging drum is also used to command the inker key motors. Feedback is also used to update the inker propagation delay and dynamic model used to determine how much the inker keys need to be adjusted based on the pixel count stream.

  • Publication number: 20120282478
    Abstract: The present invention pertains to a process for depositing multi-component and nanostructured thin films. Various parameters are monitored during the process to produce the structure of the thin films, on one hand the residence time of the gas mixture in the reactor is controlled by the pumping rate, on the other side to generate the plasma direct current (DC) or radio frequency (RF) sources are used, plus the combination of three unbalanced magnetrons allows alternative emission of elements that make up the multi-component and nanostructured films. The process is monitored by an optical emission spectrometer (EOE) and a Langmuir probe (SL), the EOE can follow the emission corresponding to the electronic transitions of atoms and molecules in the plasma. Emissions occur in the visible, infrared and ultraviolet domains. The relationships between spectral networks of different elements have been identified that ensure structural characteristics of thin films.

  • Patent number: 7965969
    Abstract: According to aspects of the embodiments, there is provided a method of optimizing an electro-photographic reproduction machine having a fusing subsystem and an air knife. The methods acquire at least one electro-photographic reproduction machine objective and media characteristic; and the acquired objective and characteristic are used to determine values for the pressurized air emitted from the air knife, the position of the air knife, and the rotation of the air knife relative to a fuse roll in the fusing subsystem. The methods further disclose acquiring the leading edge of the media being stripped and then using the beam strength of the media to assist in stripping the body of the sheet. The air knife can be controlled by a controller or a processor based on determined optimization parameter values that relate to objectives and media characteristics.

  • Publication number: 20040163665
    Abstract: A teeth cleaning implement includes a dental floss supply reel located within a housing that serves as a handle for maniuplating the implement during a teeth cleaning operation. The dental floss is unwound from the reel through an elongated tubular guide that projects from the housing. The dental floss extends from the tubular guide to a second tubular guide, and through this second guide into the housing and back onto the supply reel. The exposed section of the dental floss between the two guides can be moved back and forth in the teeth spaces to achieve a teeth cleaning operation. Periodically the floss supply reel can be rotated to expose a new section of floss.

  • Patent number: 6687479
    Abstract: A printing apparatus includes a guide member for directing sheets toward a transfer zone. The guide member defines a set of ribs which hold the sheets above the main surface of the guide member. Thus, any stray marking material which lands on the guide member is relatively unlikely to contact a sheet moving over the guide member.
