  • Patent number: 10836488
    Abstract: A drone comprises at least one propeller for generating lift and an article containment area for containing an article to be carried by the drone. The floor of the article containment area comprises a dynamic support surface for supporting the article and allowing the article to move into, out of and through the article containment area. The dynamic support surface may be a conveyor belt forming the floor of the article containment area.

  • Patent number: 10631410
    Abstract: The present disclosure is related to printed circuit board packages and methods of assembly that may be used in the fabrication of electrical devices. Printed circuit board packages may be manufactured by stacking printed circuit board assemblies. Each printed circuit board assembly may have multiple printed circuit boards supported by a resin mold. The printed circuit board assemblies may be shaped to improve space utilization efficiency and to accommodate large electrical components that are attached to the printed circuit board package.

  • Patent number: 10455738
    Abstract: A circuit board assembly in an electronic is disclosed. To conserve space in the electronic device, the circuit board assembly includes stacked circuit boards in electrical communication with each other, such as a first circuit board stacked over a second circuit board. Each circuit board may include multiple surfaces that carry operational components. Moreover, the first circuit board may include a first surface and the second circuit board may include a second surface facing the first surface. The first and second surfaces may include operational components in corresponding locations. Also, the operational components may include corresponding shapes such that one component is positioned in another component. The components may electrically connect to each other. Also, the circuit board assembly may include EMI shields around an outer perimeter in order to shield the operational components form EMI and to components in the electronic device from EMI emanating from the operational components.

  • Patent number: 7818683
    Abstract: A method of a navigational path includes enabling a user to successively display a plurality of web pages; maintaining a full breadcrumb path that includes a link to each of the previously displayed pages; displaying a shortened breadcrumb path on a current page, the shortened breadcrumb path including fewer links than the full breadcrumb path, and displaying the full breadcrumb path only upon request. A method of representing a current location within a hierarchical structure of a web site or web application includes maintaining a hierarchical map of the web site or web application; generating a web page that has a predetermined level within the hierarchical map; displaying a hierarchical structure selector on the web page, and when the displayed hierarchical structure selector is selected by a user, displaying an indication of the predetermined level and a link to each hierarchically higher level of the generated web page.

  • Patent number: 4540884
    Abstract: In a quadrupole ion store or ion trap type mass spectometer, significantly improved mass selection is achieved by simultaneously trapping ions within the mass range of interest and then scanning the applied RF and DC voltages or the frequency .omega. to sequentially render unstable trapped ions of consecutive specific masses. These are passed out through apertures in an end cap to a high gain electron multiplier to provide a signal indicative of the ion mass. Sensitivity and mass resolution is also enhanced by operating the ion trap at a relatively high pressure in the range 1.times.10.sup.-1 to 1.times.10.sup.-5 torr. The presence of collision gas molecules, such as helium, improves sensitivity and mass resolution. In addition, the structure itself is built of stacked units, sealed by O-rings, which are easily disassembled for cleaning.

  • Patent number: 4388531
    Abstract: An ionizer adapted to be placed in a vacuum envelope for providing ions of a sample to be analyzed is disclosed herein and includes an electron source, ion accelerating and focusing electrodes and an interchangeable ionization chamber including a first opening for allowing electrons to enter the chamber and an exit opening to allow ions to exit said chamber. The ionization chamber is supported in cooperative relationship with the electron source and accelerating and focusing electrodes whereby electrons enter the chamber through the first opening and form sample ions in the chamber which then exit the chamber through the exit opening toward said accelerating and focusing electrodes.
