  • Publication number: 20150015293
    Abstract: A structure and method for providing a contact pin between a device under test (DUT) and a load board which provides upper and lower contact point which are axial aligned is disclosed. The pin has an upper (30) and lower (32) section and a hinge in between which allow flex of both upper and lower contact (24/26) which, but the axial alignment can provide a direct replacement for POGO pins but with greater reliability. It also includes a structure and method for removing upper pins 230 by use of a modified hinge 244a. In an alternate embodiment, the lower section includes a leg extension 320 and a sliding contact land 360 which slides against an aperture in the housing. A spacer 342 provides space for decoupling components on the load board. The hinge may include a truncated cylinder 40b which is configured to permit remove of the upper pin without removal of the lower.

  • Patent number: 8926369
    Abstract: An electrical connector can receive a substrate having conductive tracks. The connector includes a housing with a port and at least one alignment feature that together define a direction of insertion. At least three function pins mounted to the housing each include contacts that electrically connect to one of the conductive tracks of a substrate inserted in the connector. A sense pin mounted to the housing has a contact that electrically connects to at least one of the conductive tracks of an inserted substrate. The sense pin can include a plurality of electrically-connected segments, each segment extending substantially parallel or substantially perpendicular to the direction of insertion of the substrate. Systems and methods for detecting an analyte in a bodily-fluid sample are also described.

  • Publication number: 20140311602
    Abstract: An integrated valve assembly, which integrates two check valves and a solenoid assembly which functions as a purge valve. When the solenoid assembly is in an open position, during a first mode of operation, vacuum pressure places the first check valve in an open position and the second check valve in a closed position, and during a second mode of operation, pressurized air places the first check valve in a closed position, and vacuum pressure generated by a venturi valve member places the second check valve in an open position. Each check valve utilizes a nylon insert along with an over molded rubber seal. The design of the check valves prevents actuation at low vacuums and flows when the vehicle is shut off. The integrated valve assembly eliminates the need for an OBD relief valve, and simplifies the EVAP system, saving costs, complexity, and eliminates several possible leak connections.

  • Publication number: 20140215278
    Abstract: An embodiment described herein includes a method for input channel voting. The method includes steps for sorting the three input values by magnitude into a high input value, a middle input value, and a low input value. The three input values are then tested. The testing includes subtracting the middle input value form the high input value to calculate a first difference, and comparing an absolute value of the first difference to a failure threshold. A first intermediate value is determined based on the comparison of the first difference to the failure threshold. The testing also includes subtracting the middle input value from the low input value to calculate a second difference, and comparing the second difference to the failure threshold. A second intermediate value is determined based on this comparison. The first intermediate value and second intermediate value are averaged to produce an output based on the three input values.

  • Patent number: 8784549
    Abstract: An aqueous inkjet ink set for use in continuous inkjet printing comprising at least one cyan ink, at least one yellow ink, at least one magenta ink, and at least one black ink, wherein each ink of the ink set comprises dispersed pigment particles and at least one surfactant selected to provide a 10-ms dynamic surface tension of less than 54 mN/m for each ink. The invention relates to continuous ink jet printing of aqueous pigmented ink compositions recycled from main ink supply reservoirs, employing a printer with drop ejectors and a drop deflector and non-printing drop catchers capable of returning unprinted ink to the fluid delivery systems following the capture of non-printing drops. The pigmented ink jet ink compositions provide for particularly suitable fluid properties on the drop catcher face that minimize printing defects that can occur during drop deflection during the printing of high dynamic range images at high speed.

  • Patent number: 8701630
    Abstract: Methods and systems are provided for improving fuel usage while addressing knock by adjusting the use of spark retard and direct injection of a knock control fluid based on engine operating conditions and the composition of the injected fluid. One or more engine parameters, such as EGR, VCT, boost, throttle position, and CMCV, are coordinated with the direct injection to reduce torque and EGR transients.

  • Publication number: 20130122207
    Abstract: A method of forming a ceramic coating, the resulting ceramic coating, and structures produced by forming the ceramic coating on a ceramic fiber shape. The method includes forming an aqueous mixture containing water, an alumino-silicate precursor, and a dispersion of a ceramic fiber material. The alumino-silicate precursor contains a colloidal suspension of silica particles, silica fume particles, and micron-sized and submicron-sized alumina particles. The ceramic fiber material includes micron-sized and submicron-sized ceramic fibers. The aqueous mixture is applied to a surface of a ceramic fiber shape, after which the aqueous mixture is cured to form a ceramic coating that contains the ceramic fiber material dispersed in an alumino-silicate matrix.

  • Patent number: 8413730
    Abstract: A wellhead housing has a telescoping casing hanger with an actuator mechanism to provide for direct transfer of casing and pressure loads to the housing. The transfer of casing and pressure loads occurs even in conditions where the telescoping casing hanger may be set in a high position in the wellhead housing on a load shoulder. The transfer of casing and pressure loads also occurs in conditions where the telescoping casing hanger may be set in an earlier installed casing hanger in the wellhead housing for a larger diameter casing string.

  • Publication number: 20130070031
    Abstract: A method of printing an image with a continuous inkjet printer system employing a jetting module including a nozzle in fluid communication with a liquid ink source and a catcher including a liquid drop contact face; wherein the liquid ink is an aqueous inkjet black ink comprising a black colorant and at least one surfactant selected to provide a 10-ms dynamic surface tension of less than 54 mN/m. Full color images may be printed by further employing at least second, third and fourth jetting modules and yellow, magenta and cyan inks each also comprising a surfactant selected to provide a 10-ms dynamic surface tension of less than 54 mN/m for each ink. The ink compositions provide for fluid properties on the drop catcher face that minimize printing defects that can occur during drop deflection during the printing of high dynamic range images at high speed.
