  • Patent number: 8350933
    Abstract: A method, apparatus and computer program product are provided for recovering a haze-free image given a single input image. The method may include receiving a single input image I, wherein the input image is made up of a plurality of pixels. A surface radiance vector J of the input image I may be modeled as a product of a surface albedo coefficient R and a shading factor l. The method may further include determining, for each of the plurality of pixels, a value of a transmission t of the pixel, such that a covariance C? between the transmission t and the shading factor l is minimized, and recovering the surface radiance vector J based at least in part on the determined value of the transmission t for each pixel.

  • Patent number: 6817697
    Abstract: The present invention is directed to systems and methods for formatting hardware for a printhead, for use in a printing device. The systems and methods of the present invention can support the formatting function with hardware formatting logic. This hardware formatting logic can support multiple printhead platforms. The hardware formatting logic of the present invention can perform bit shifting, resolution reduction, bit per pixel reduction, data masking for shingling, and input data sourcing. The present invention can also include a system processor further including an embedded ARM processor which can fetch and execute instructions and/or firmware. These instructions can direct the embedded processor to configure a format block included within the system processor. The format block can be configured by the system processor via one or more control registers.

  • Patent number: 6394503
    Abstract: The present invention relates to a system and a method for securing tubing which includes a reservoir, preferably being a printer cartridge, having a rigid wall with interior and exterior surfaces, a rigid restraining member for a tube, and the restraining member further having a passage therethrough. In one embodiment, the invention includes at least one locking lever with top and bottom ends, the locking lever having at least one notch proximate to the top end and the bottom end is pivotably attached to the interior surface of the reservoir wall, and the restraining member is alternately attached to the top end of the locking lever. In another embodiment, the locking lever is rigidly attached to the interior surface of the reservoir and the restraining member is alternately attached to the reservoir. In a further embodiment, the restraining member is attached to interior of the reservoir wall by at least two locking arms.

  • Patent number: 6145971
    Abstract: A system and method for supplying ink to a print head on a moving carrier using the acceleration of the print head carrier to assist in pumping the ink. The system includes an ink supply reservoir and an ink pump on the moving carrier where the ink pump has a carrier reservoir including at least one flexible wall that deforms from inertial resistance to acceleration of the moving carrier, a print head, and a pressure regulator in fluid communication with the carrier reservoir and the print head. The system also has an ink supply tube in fluid communication with the ink supply reservoir and the carrier reservoir such that acceleration of the moving carrier and ink pump deforms the flexible wall and thereby pumps ink from the ink supply reservoir to the carrier reservoir and from the carrier reservoir to the print head, or solely to the carrier reservoir.

  • Patent number: 6003069
    Abstract: A client/server printer driver including a client-side subsystem capable of transmitting a print job to a server-side subsystem capable of receiving the print job from the client-side and processing the print job and sending the processed data back to the client-side for output. A client/server printer driver including a client-side subsystem capable of dividing the print job into portions to be processed client-side and server-side and then transmitting the server-side portions of the job to a server-side subsystem capable of processing the client-side portions of the print job to create and receiving the processed server-side portions. The system has a server-side subsystem capable of receiving the server-side portions from the client-side subsystem and processing these portions to create processed server-side portions and transmitting the server-side portions to the client-side.

  • Patent number: 5748188
    Abstract: A hypertext data processing system wherein graphical data is sent from a server to a client computer using extensions to the Hypertext Markup Language (HTML). The client computer parses the graphical data and formulates an object representative of the graph to display. The object is passed to a graph server which displays the graph.

  • Patent number: 5435573
    Abstract: A wireless remote control system is provided. The remote control system includes a remote unit and a receiver unit, and may be utilized in connection with a video game system or other controllable system. The receiver unit includes a plurality of detectors for detecting a signal transmitted by a remote unit. An angle-limiting device is coupled to each detector for limiting the signal which may be received by the particular detector to that signal which is transmitted from a particular location. In one embodiment, the angle-limiting device may limit the signal received by the detector to that signal transmitted from within a specified angular range relative to the detector. In a preferred embodiment, the angle-limiting devices coupled to the plurality of detectors may be arranged so that each angle-limiting device allows a signal to be received by the respective detector from a unique angular region. In another embodiment, the angular regions may be overlapping.

  • Patent number: 5404048
    Abstract: The invention relates to a liquid sensing switch for use primarily in sensing the bilge water level aboard a boat. The switch is designed with a high input impedance and a high trigger sensitivity, so that the presence of a liquid may be detected by using a remotely located single wire probe. The probe is able to sense immersion into low conductivity liquids or into liquids where no hardwired ground is provided, such as within fiberglass boat hulls. In order to prevent false triggering and cyclic operation of the bilge pump, the liquid sensing switch provides a time delay before it is activated, as well as a further time delay before being deactivated.
