  • Publication number: 20210337097
    Abstract: Analog power savings is achieved by pre-charging only those pixels of a sensor array that are needed as determined responsive to any one of a power configuration, image size, image position of interest, desired/selected frame rate, desired/selected resolution, etc. To that end, the solution presented herein selects one or more sensor segments, each comprising a subset of pixels of the sensor array, and only pre-charges the pixels in the selected segment(s). In so doing, the solution presented herein provides a power savings proportional to the number of uncharged pixel circuits.

  • Patent number: 7187532
    Abstract: A device and a method for stabilising a metallic object of magnetic material. The metallic object is transported along a transportation path or plane. The plane includes a transportation direction and is parallel to the longitudinal direction of the object therein. A sensor is arranged to sense the valve of a parameter depending on the position of the object with respect to the plane. An electromagnetic actuator is arranged to apply a magnetic force to the object in respone to the sensed position. The magnetic force has a force component directed transversely to the transportation direction and transversely to the plane.

  • Patent number: 6783069
    Abstract: A mouse incorporating a camera captures an image of embedded data from a substrate under the mouse. The embedded data in the image is decoded to determine address or location information coded in the embedded data. Based on the decoded information and other user input signals, such as mouse button selection signals, the computer executes operations. The mouse also has a display controlled by the computer for providing visual feedback to a user. The display might generate an image of the substrate area under the mouse, making it appear to the user as if they are looking through the mouse directly onto the substrate. The display may also generate visual feedback regarding operations occurring in the computer, such as selection or other computer operations.

  • Publication number: 20010013884
    Abstract: An ink refill system, ink refill station, ink refill kit, and method to replenish both pigment and/or dye-based inks in cartridges of ink jet printers, plotters, copiers, and fax machines. A number of embodiments are described. The principal embodiment is a refill kit characterized by a spring clip assembly removably mountable on a cartridge. The clip assembly has mounted upon it a member which is sealingly connectable to the vacuum relief valve port or bubble generator on the bottom of the ink jet cartridge, an internal channel of the clip assembly connecting the bubble generator port and sealing member to a receptacle which removably connects to a flexible ink refill bottle, which bottle is adapted to both inject ink into, and remove excess air from, the cartridge via the bubble generator port. A permanently mountable footplate embodiment of this system is also described.

  • Patent number: 5988269
    Abstract: A plate heat exchanger for two or more flowing media may according to the invention be designed so that the front and rear cover plates (1, 8) of the exchanger act as channel defining walls for a flowing heat exchanging medium, and so that the tube connections at the inlet and outlet ports (10-13) can be established in a common plane. This is obtained thereby that the front and rear cover plates (1, 8) together with the adjacent first (2) and last (5) channel forming plates define distribution channels (18) crossing the direction between adjacent inlet and outlet ports.

  • Patent number: 5686948
    Abstract: A method for refilling an ink cartridge which contains an elastic bladder within the ink reservoir cavity that is connected to outside pressure. The methodology of the invention teaches how to seal and unseal the bladder and ink regions in sequential steps and how to inject ink into the ink reservoir cavity so it may be re-used and not discarded.

  • Patent number: 5572852
    Abstract: A kit for opening and sealing a cartridge having an interior ink reservoir coupled to an access port extending from a reference surface comprises a rigid plunger, a plate and a rigid spherical plug. The plate has one or more regions of varying thickness and a bottom surface which is complementary to the reference surface on the cartridge. The bottom surface of the plate may be matched to the reference surface of the cartridge in two distinct orientations such that a sealed access port may be opened, refilled and sealed with a rigid spherical plug by extension of the plunger through the plate in each orientation to a depth determined by the length of the plunger, the thickness of the plate in each orientation, the depth of the access port in the cartridge, and the diameter of the spherical plug.

  • Patent number: 5488400
    Abstract: A method of refilling an ink jet cartridge with ink. The cartridge has a housing which encloses an internal ink reservoir extending between top and bottom ends thereof, an ink fill aperture extending through the housing near its top end, and a means for sealing the ink fill aperture. The cartridge further includes a bladder in the reservoir, an air port affixed to the top of the housing, and a spring means which biases the bladder toward a minimum volume state. According to the method, the cartridge is positioned with its top end above its bottom end, the ink fill aperture is unsealed, and the air port is sealed. The bladder is inflated to establish an internal volume in a predetermined range. Ink is then injected into the reservoir through the ink fill aperture. The ink fill aperture is then sealed, and the air port unsealed.
