  • Patent number: 10145822
    Abstract: A probe, including a first input configured to receive a first input signal, a second input configured to receive a second input signal, a first cable connected to the first input, a second cable connected to the second input, an electronically adjustable delay connected to the first cable, the electronically adjustable delay configured to delay the first input signal to remove a skew between the first input signal and the second input signal, and an amplifier configured to receive the first input signal from the electronically adjustable delay and a second input signal.

  • Publication number: 20050134628
    Abstract: In an inkjet printer using ink reservoirs located physically remote from the print heads, tubes are used to deliver ink from the ink reservoirs to the print heads. Air initially present within the tubes can interfere with the proper operation of the print heads and cause print head reliability problems Additionally, air present within the tubes can interfere with the proper flow of ink from the ink reservoirs to the print heads through the tubes. An embodiment of a fluid continuity measurement apparatus includes current sources for each of the tubes. Each of the current sources delivers a substantially constant current to the corresponding tube. Voltage measurement circuits are coupled across each of the tubes. Each of the voltage measurement circuits generates an output corresponding to the voltage across the corresponding tube. The voltages appearing between the ends of the tubes changes as the volume of the air within the tubes changes.

  • Publication number: 20050093908
    Abstract: A printing system includes an ink dispenser configured to dispense ink upon a print medium, a condenser configured to condense vapor into a condensate and a receptacle configured to collect the condensate. The receptacle is perforated to permit a portion of the condensate to evaporate.

  • Patent number: 5761161
    Abstract: The present invention provides an Input/Output station of an automated storage and retrieval system, or library, which uses an elevator mechanism to vertically translate a cartridge or a magazine containing a plurality of cartridges from a maximum vertical position above the top surface of the library to a minimum vertical position beneath the top surface and internal to the library. The Input/Output station is aligned with the other components of the library such that the vertical path of the elevator mechanism does not interfere with the path of the accessor. The operation of the Input/Output station does not pause the accessor and thus, does not interfere with the operation of the other automated processes within the library. Cartridges can be added to or removed from the library using the Input/Output station while the accessor is moving a different cartridge from a storage cell in the storage array to a drive.
