Patent number: 11476334Abstract: Techniques and mechanisms for providing functionality of a transistor which comprises a conformal layer of a gate work function silicide. In an embodiment, the transistor comprises a channel region and a gate dielectric which extends and adjoins the channel region. The gate dielectric also adjoins a layer structure of the transistor, the layer structure comprising a silicide. The silicide includes silicon and a component D which comprises a non-metal element from one of Groups IIIa, IVa, or Va. In another embodiment, the silicide further comprises a component M which includes a transition metal element from one of Groups IVb, Vb, VIb, VIIB, or VIIIb and/or which includes a metal element from one of Groups IIIa, IVa, or Va.Type: GrantFiled: February 8, 2018Date of Patent: October 18, 2022Assignee: Intel CorporationInventors: Orb Acton, Joseph Steigerwald, Anand Murthy, Scott Maddox, Jenny Hu

Patent number: 9748430Abstract: A staircase avalanche photodiode with a staircase multiplication region composed of an AlInAsSb alloy. The photodiode includes a buffer layer adjacent to a substrate and an avalanche multiplication region adjacent to the buffer layer, where the avalanche multiplication region includes a graded AlInAsSb alloy grown lattice-matched or psuedomorphically strained on either InAs or GaSb. The photodiode further includes a photoabsorption layer adjacent to the avalanche multiplication region, where the photoabsorption layer is utilized for absorbing photons. By utilizing AlInAsSb in the multiplication region, the photodiode exhibits a direct bandgap over a wide range of compositions as well as exhibits large conduction band offsets much larger than the smallest achievable bandgap and small valance band offsets. Furthermore, the photodiode is able to detect extremely weak light with a high signal-to-noise ratio.Type: GrantFiled: June 17, 2016Date of Patent: August 29, 2017Assignees: Board of Regents, The University of Texas System, University of Virginia Patent FoundationInventors: Seth Bank, Scott Maddox, Wenlu Sun, Joe Campbell

Patent number: 6574865Abstract: A wheel bearing assembly for supporting a wheel is provided. The assembly includes a spindle defining a rotational axis and a support member for supporting the spindle. A wheel hub has a flange for securing the wheel thereto. The wheel hub is supported on the spindle and is rotatable about the rotational axis. A bearing assembly has first and second bearing members in spaced relationship from one another with a plurality of bearings interposed between the bearing members to permit relative rotation between the bearing members about the rotational axis. The first bearing member is arranged adjacent to the spindle and the second bearing member is arranged adjacent to either the wheel hub or the support member. An inner surface of the first bearing member has an annular counterbore. The spindle is deformed into the counterbore to axially secure the first bearing member to the spindle and prevent relative rotation between the spindle and the first bearing member about the rotational axis.Type: GrantFiled: April 5, 2002Date of Patent: June 10, 2003Assignee: Delphi Technologies, Inc.Inventors: Steven Eugene Meeker, Richard Allen Scheufler, Jr., George Leonard Hurrell, II, Scott A. Maddox, Christopher J. Zuck

Publication number: 20030103795Abstract: The present invention uses a pressurized fluid reservoir mounted on a mop to deliver cleaning solution on a floor. The liquid in the reservoir is dispensed at the user's discretion from a biased-closed spray nozzle downstream from the reservoir. Three different methods of creating a pressurized reservoir are: using a compressed gas cartridge either regulated or not, using a hand-actuated pump, and utilizing an aerosol can with a standard propellant of known vapor pressure. The aerosol can either is used strictly as a propellant creating pressure on a reservoir or the aerosol can contains a cleaning solution or the like as well as propellant all in one replaceable can.Type: ApplicationFiled: December 2, 2002Publication date: June 5, 2003Applicant: Innovative Products and Design, Inc.Inventors: Anthony Scott Hollars, Randall Scott Maddox
