  • Patent number: 9787211
    Abstract: An AC power converter converts power from an AC power source to an AC load. A DC power holding source is coupled to an input half-bridge switch, a common half-bridge switch and an output half-bridge switch. A controller is coupled to at least two of the input half-bridge switch, the common half-bridge switch, and an output half-bridge switch. The controller switches the input half bridge at the first switching frequency in boost mode and at the line frequency in buck mode. The controller also switches the output half bridge switch at the first switching frequency in buck mode and at the line frequency in boost mode. Input and output low pass filters can eliminate switching frequency energy from entering the AC source and load. The converter maintains a DC power holding source voltage slightly above peak AC input voltage and significantly less than twice the peak AC input voltage.

  • Patent number: 9768705
    Abstract: An AC power converter converts power from an AC power source to an AC load. A DC power holding source is coupled to an input half-bridge switch, a common half-bridge switch and an output half-bridge switch. A controller is coupled to the input half-bridge switch, the common half-bridge switch, and an output half-bridge switch to generate at least two control signals at a common switching frequency, wherein the controller generates the at least two control signals with a phase difference there between chosen to cause a ripple frequency in both the input low pass filter and the output low pass filter to be double the common switching frequency. An input low pass filter can eliminate switching frequency energy from entering the AC power source. An output low pass filter can eliminate switching frequency energy from entering the AC load.

  • Publication number: 20080113156
    Abstract: Plural film layers are disposed on a substrate. Each film layer has regions devoid of film material, thus forming film layer cavity openings. Each film layer has its cavities arranged to provide fluid coupling with its adjacent film layer or layers. The film layer cavities form a traverse channel coupling the top and bottom film layers and also one or more lateral channels coupling cavity openings in the top film layer. The film layer traverse channel couples with a substrate channel that extends from the substrate top surface to one or more of its other surfaces. A device such as a fluid dispenser, fluid ejector, sensor or bioprocessing device is disposed on the top film layer and fluidly coupled to the plural film layers traverse and lateral channels. The traverse channel and the one or more lateral channels are arranged to transport or flow one or more fluids.

  • Publication number: 20070138582
    Abstract: This describes a starting structure and method for forming a micro-mechanical device. These devices have several uses in both government and commercial applications. The starting structure can be sold or supplied to others who will then make a final product, or it can be used directly to make a final product. An appropriate use of this starting structure is to make deformable devices useful in an inkjet printing device.

  • Publication number: 20070132812
    Abstract: A printing system includes a print head to deliver ink to an image receptor and at least one ink reservoir to deliver ink to the print head. Driving circuitry provides signals to the print head to control delivery of the ink and a flexible circuit interposed between the print head and the ink reservoirs connects the driving circuitry to the print head.

  • Publication number: 20050040563
    Abstract: The invention relates to a method for producing plastic hollow bodies which are filled, at least partially, with foam particles. The plastic hollow body is produced by rotational moulding and is filled, at least partially, in the rotational mould with foam particles. Foam particles which are made of the same type of a polyolefinic plastic material, from which the wall of the hollow body is also made, are used in order to simplify the recycling.

  • Patent number: 6540315
    Abstract: System and methods for using a fluid ejection system to distribute fluid drop density of a region between at least two overlapping swaths having pixels on a receiving medium. Using the method, overlapping swaths are stitched together by distributing a fluid ejection pattern between the overlapping swaths within the overlapped region. Because small drops of fluid can be distributed within a single region, the fluid ejection pattern can be controlled and intermediate density regions can be created by distributing the fluid of drops within a region between two fluid ejector heads or between two swaths of the same fluid ejector head. The distribution can be linear or non-linear. Furthermore, overlapping swaths are stitched together by randomly varying a stitch location within the overlapped region. In this case, a stitch location is randomly varied in the slow scan direction.
