  • Patent number: 11964174
    Abstract: A mounting device may include a top plate including a cone-shaped center portion, a flange coupled to the cone-shaped center portion, a number of apertures defined in the flange, and a number of fasteners engaged with the apertures to couple the top plate to a surface of a structure. The flange seals a bottom side of the top plate to the surface of the structure. The flange includes a seal coupled to the bottom of the flange. The cone-shaped center portion has a convex paraboloid shape. The flange includes at least one surface that is parallel to a surface of the structure, and a transition between the cone-shaped center portion and the flange forms an angle. The top plate has a diameter sufficient to displace a load greater than 50 pounds over the surface of the structure.

  • Publication number: 20240061916
    Abstract: A method and apparatus for a distributed service provider system performing authentication for access to, and deletion of, user data, is described. The method may include monitoring service system responses to requests for user data associated with a user identifier. The method may further include ordering the monitored user data based on one or more of a sensitivity level and a veracity level associated with each of the monitored user data, and filtering out user data from the monitored user data that is not suitable for presenting to the user for identity verification. Furthermore, the method can include selecting a subset of the filtered user data for a series of identity verification questions for generating and transmitting, to the user system, a series of security verification questions, each security verification question based on one of the selected subset of the filtered user data.

  • Patent number: 9180481
    Abstract: A paint station may include a frame with a table attached to it. A track may run along the length of the table. A bridge may be connected to the track and may move along the track. The bridge may extend across the width of the table. A painting component may be attached to the bridge and may move along the bridge. Therefore the painting component may run along two axes over the table. A computer may be connected to the paint station to direct the movement of the painting component along the two axes. A user may place a clothing apparel on the table and may input a command to paint a desired design on the clothing apparel.

  • Patent number: 8822256
    Abstract: A method for fabricating infrared sensors is disclosed. a chalcogenide layer is initially deposited on a substrate. A group of vias is then formed within the chalcogenide layer. After the vias have been converted to a group of studs, a vanadium oxide layer is deposited on the chalcogenide layer covering the studs. Next, the vanadium oxide layer is separated into multiple vanadium oxide membranes. After the chalcogenide layer has been removed, each of the vanadium oxide membranes is allowed to be freestanding while only supported by a corresponding one of the studs. The vanadium oxide membranes will be used as infrared sensors.

  • Patent number: 8440501
    Abstract: A memory or switching device includes a mesa and a first electrode conforming to said mesa. The device also includes a second electrode and a phase-change or switching material disposed between said first and second electrodes. The phase-change or switching material is in electrical communication with the first and second electrodes at a first contact region and a second contact region respectively. Also described is a method for making a memory or switching device. The method includes providing a first insulator and configuring the first insulator to provide a mesa. A first conductive layer is provided conforming to the mesa. A phase-change or switching material is provided over a portion of the first conductive layer, and a second conductive layer is provided over the phase-change or switching material.

  • Publication number: 20060070965
    Abstract: Storage devices allow for the efficient storage of objects which include a substantially cylindrical member such as a fishing rod. The storage device includes a support member which is coupled to a retaining member. The retaining member includes multiple protruding members positioned substantially perpendicular to the support member to form multiple tapered slots which can have openings of varying widths. The substantially cylindrical member of an object is inserted into the tapered slot to create a friction fit to retain the object in a substantially vertical position.
