Patent number: 10276289Abstract: In a general aspect, a position detection system includes a magnetic field generator configured to generate a time-varying magnetic field. The magnetic field generator includes a carrier assembly that defines a first axis of rotation and comprises a permanent magnet having a center of mass. The magnetic field generator also includes a drive assembly that is coupled to the carrier assembly and configured to act on the carrier assembly to rotate the permanent magnet simultaneously about the first axis of rotation and a second axis of rotation. The second axis of rotation intersects the first axis of rotation at an intersection that is offset from the center of mass of the permanent magnet. The position detection system additionally includes a computer device configured to determine a position of a sensor based on magnetic field measurements obtained by the sensor in the time-varying magnetic field.Type: GrantFiled: June 1, 2018Date of Patent: April 30, 2019Assignee: Ommo Technologies, Inc.Inventors: Jonah William Kirby, Matthew Pickett, Minjie Zheng, Jonathan Feldkamp

Patent number: 9172035Abstract: Memristors and their fabrication are provided. A first dielectric layer is formed over one or more conductive pathways. Vias are formed in the dielectric layer and filled with conductive material. A second dielectric layer is formed there over, and vias are formed aligned with and extending to the filled vias. A reactant fluid is introduced into the vias such that a reacted portion of the conductive material is defined within the filled vias. The vias in the second dielectric layer are then filled with conductive material such that memristors are defined. Conductive pathways are then formed over and in contact with the memristors such that each is individually addressable.Type: GrantFiled: December 12, 2011Date of Patent: October 27, 2015Assignee: Hewlett-Packard Development Company, L.P.Inventors: Matthew Pickett, Janice Nickel

Patent number: 8912520Abstract: A nanoscale switching device has an active region disposed between two electrodes of nanoscale widths. The active region contains a switching material that carries mobile ionic dopants capable of being transported over the active region under an electric field to change a resistive state of the device. The switching material further carries immobile ionic dopants for inhibiting clustering of the mobile ionic dopants caused by switching cycles of the device. The immobile ionic dopants have a charge opposite in polarity to the charge of the mobile ionic dopants, and are less mobile under the electric field than the mobile ion dopants.Type: GrantFiled: July 21, 2010Date of Patent: December 16, 2014Assignee: Hewlett-Packard Development Company, L.P.Inventors: Jianhua Yang, Matthew Pickett, Gilberto Ribeiro

Patent number: 8891284Abstract: A memristor based on mixed-metal-valence compounds comprises: a first electrode; a second electrode; a layer of a mixed-metal-valence phase in physical contact with at least one layer of a fully oxidized phase. The mixed-metal-valence phase is essentially a condensed phase of dopants for the fully oxidized phase that drift into and out of the fully oxidized phase in response to an applied electric field. One of the first and second electrodes is in electrical contact with either the layer of the mixed-metal-valence phase or a layer of a fully oxidized phase and the other is in electrical contact with the layer (or other layer) of the fully oxidized phase. The memristor is prepared by forming in either order the layer of the mixed-metal-valence phase and the layer of the fully oxidized phase, one on the other. A reversible diode and an ON-switched diode are also provided. A method of operating the memristor is further provided.Type: GrantFiled: September 4, 2009Date of Patent: November 18, 2014Assignee: Hewlett-Packard Development Company, L.P.Inventors: R.

Publication number: 20120146184Abstract: A memcapacitor device includes a memcapacitive matrix interposed between a first electrode and a second electrode. The memcapacitive matrix includes deep level dopants having a first decay time constant and shallow level dopants having a second decay time constant. The second decay time constant is substantially shorter than the first decay time constant. The capacitance of the memcapacitor device depends upon an initial voltage applied across the memcapacitive matrix and a time dependent change in capacitance of the memcapacitor device depends upon the first decay time constant. A method for forming a memcapacitive device is also provided.Type: ApplicationFiled: August 28, 2009Publication date: June 14, 2012Inventors: Matthew Pickett, Julien Borghetti, Jianhua Yang

Publication number: 20120113706Abstract: A memristor (100, 100?, 100?) based on mixed-metal-valence compounds comprises: a first electrode (115); a second electrode (120); a layer (105) of a mixed-metal-valence phase in physical contact with at least one layer (110, 110a, 110b) of a fully oxidized phase. The mixed-metal-valence phase is essentially a condensed phase of dopants for the fully oxidized phase that drift into and out of the fully oxidized phase in response to an applied electric field (125). One of the first and second electrodes is in electrical contact with either the layer of the mixed-metal-valence phase or a layer (110a) of a fully oxidized phase and the other is in electrical contact with the layer (or other layer (110b)) of the fully oxidized phase.

Publication number: 20060289091Abstract: The present invention relates to the internal gettering of impurities in semiconductors by metal alloy clusters. In particular, intermetallic clusters are formed within silicon, such clusters containing two or more transition metal species. Such clusters have melting temperatures below that of the host material and are shown to be particularly effective in gettering impurities within the silicon and collecting them into isolated, less harmful locations. Novel compositions for some of the metal alloy clusters are also described.Type: ApplicationFiled: June 5, 2006Publication date: December 28, 2006Inventors: Anthony Buonassisi, Matthias Heuer, Andrei Istratov, Matthew Pickett, Mathew Marcus, Eicke Weber

Patent number: 7093461Abstract: A receiver-dryer of an integrated receiver-dryer-condenser for an air-conditioning system that maximizes a liquid phase of refrigerant therein for return to a sub-cooling stage of a condenser. A receiver-dryer vessel includes a base wall, a side wall extending from the base wall, and a concave end wall terminating the side wall. A refrigerant inlet pipe extends into the interior of the vessel and terminates in an exit end that faces the concave end wall of the vessel. The refrigerant inlet pipe is adapted for directing refrigerant into contact with the concave end wall such that the refrigerant impinges on the concave end wall for improved dispersion into a gaseous phase that accumulates in the upper portion of the vessel and a liquid phase that flows down the walls of the vessel to accumulate in the lower portion of the vessel and for improved separation of the liquid phase and to return to the sub-cooling stage of the condenser for improved sub-cooling of the liquid phase of the refrigerant.Type: GrantFiled: March 16, 2004Date of Patent: August 22, 2006Assignee: Hutchinson FTS, Inc.Inventors: Chhotu N. Patel, Paul Matthews Pickett, Jr.

Patent number: 6193283Abstract: An engagement device for a cantilevered conduit connection that provides an assembler with visible, audible, and tactile redundant verification that the connection is completely engaged. The engagement device assists in holding a connecting block in place to a housing. The housing includes a fastener port with a fastener fastened therein. The engagement device includes a locking portion at one end thereof, and circumscribes a portion of the fastener. The connecting block mounts to the housing and includes a fastener passage through the connecting block that mounts around the engagement device. The connecting block further includes an engagement surface that mates with the locking portion of the engagement device to assist in fastening the connecting block to the housing. The locking portion of the engagement device expands against the engagement surface of the connecting block to provide visible, audible, and tactile verification that the connecting block is completely engaged to the housing.Type: GrantFiled: October 29, 1999Date of Patent: February 27, 2001Assignee: Automotive Fluid Systems, Inc.Inventors: Paul Matthews Pickett, Jr., Robert Jay Slais
