  • Patent number: 9832911
    Abstract: An air handling unit, particularly for data center cooling, operates to cool a flow of return air from a conditioned space using a flow of ambient air. The return air is recirculated to the conditioned space as supply air. The flow of ambient air can be adiabatically cooled to a lower temperature to provide additional cooling. A flow of makeup air can be joined with the cooled return air to form the supply air, and can be sourced from the ambient environment directly or from the heated flow of ambient air.

    Abstract: An air conditioner including a frame, a fan operable to generate an airflow that moves in an airflow direction, and a first heat exchanger including a first end adjacent the air inlet, a second end adjacent the air outlet, an air inlet face that extends between the first end and the second end, an air outlet face that extends between the first end and the second end and faces opposite the air inlet face, and a longitudinal axis that extends through the first end and the second end between the air inlet face and the air outlet face. The heat exchanger is configured to transfer heat between the airflow and a cooling medium. A first heat exchanger angle is defined between the longitudinal axis of the heat exchanger and the airflow direction, and the first heat exchanger angle can be between about 3 degrees and about 20 degrees.

  • Publication number: 20070251992
    Abstract: A method of processing a check prior to electronically depositing the check includes steps of (a) attempting to print a cancellation mark on the check using an energy emitting ink, such as a luminescent ink, (b) radiating first energy, such as UV energy, toward the check, (c) determining whether second energy is emitted from the check as a result of the radiated first energy impinging upon the energy emitting ink present on the check, and (d) allowing the check to proceed to electronic deposit only if it is determined that the second energy is emitted from the check. Also, an apparatus for electronically depositing a check that implements the method.

  • Publication number: 20070251991
    Abstract: A method of processing a check prior to electronically depositing the check includes receiving the check, determining a number of existing check submission indicating marks, if any, that are present on the check, determining whether the number is less than a pre-set maximum number, discontinuing the processing of the check if it is determined that the number is not less than the pre-set maximum number, and printing a new check submission indicating mark onto the check and continuing the processing of the check if it is determined that the number is less than the pre-set maximum number. The existing check submission indicating marks may be printed with an energy emitting ink, such as, without limitation, a luminescent ink. Also provided is an apparatus adapted to implement the method just described.

  • Publication number: 20070132801
    Abstract: A system for detecting failures in a sensitive region of an inkjet printhead is described. The system includes an inkjet printer that uses a printhead for printing an image on a substrate. The image has a sensitive portion that is more sensitive to printing failures than the rest of the image. The printhead includes a first portion that prints an area of the substrate corresponding to the sensitive portion of the image. A radiant energy source is used with a photodetector located downstream from the printhead to detect background florescence from the substrate in the area of the substrate corresponding to the sensitive portion of the image that should be quenched by printing of the image. If background florescence is detected, a failure is indicated.

  • Patent number: 7223677
    Abstract: The present invention provides a method for manufacturing a semiconductor device comprising an insulating layer that includes a seed layer formed on a silicon substrate. The seed layer is formed by exposing a hydrogen-terminated surface of the silicon substrate in a substantially oxygen-free environment to a seed layer precursor comprising a methylated metal. Forming the insulating layer further includes depositing a dielectric material on the seed layer.

  • Publication number: 20050134020
    Abstract: A hitch alignment device for aligning a ball and socket of a ball and socket type hitch is disclosed. The alignment device includes a base with a winch and pivotable cable guide mounted on it. The cable guide includes a plate with an arm extending outwardly from it at an angle and an adjustable leg extending outwardly from the arm. A pulley is mounted on the leg and a cable is connected to the winch at one end, is threaded around the pulley and then through holes in the socket and ball of the hitch and is then secured. The cable is wound onto the winch to draw the ball and socket together. The cable guide can be extended and pivoted so that the pulley and therefore the cable is brought into sufficient alignment with the socket on the trailer that undue strain is not placed on the alignment device as the cable is wound onto the winch.

  • Publication number: 20040241947
    Abstract: The present invention provides a method for manufacturing a semiconductor device comprising a III-V semiconductor substrate, and an insulating layer deposited on the substrate by Atomic Layer Deposition (ALD). The use of ALD to deposit the insulating layer was found to facilitate the creation of active devices that avoid Fermi layer pinning. In addition, such insulating layer may be advantageously used as a passivation layer in III-V substrate based active devices and transistors.
