Patent number: 11974288Abstract: A method and apparatus for transmitting uplink control information (UCI) for Long Term Evolution-Advanced (LTE-A) using carrier aggregation is disclosed. Methods for UCI transmission in the uplink control channel, uplink shared channel or uplink data channel are disclosed. The methods include transmitting channel quality indicators (CQI), precoding matrix indicators (PMI), rank indicators (RI), hybrid automatic repeat request (HARQ) acknowledgement/non-acknowledgement (ACK/NACK), channel status reports (CQI/PMI/RI), source routing (SR) and sounding reference signals (SRS). In addition, methods for providing flexible configuration in signaling UCI, efficient resource utilization, and support for high volume UCI overhead in LTE-A are disclosed.Type: GrantFiled: December 28, 2022Date of Patent: April 30, 2024Assignee: InterDigital Patent Holdings, Inc.Inventors: Erdem Bala, Philip J. Pietraski, Sung-Hyuk Shin, Guodong Zhang, Allan Y. Tsai, Joseph S. Levy, Pascal M. Adjakple, John W. Haim, Robert L. Olesen, Kyle Jung-Lin Pan

Publication number: 20240084056Abstract: Elastomeric polyolefin-based ionomers and methods for making same. The ionomers can include a copolymer comprising: C2-C60 ?-olefin monomer units; optional C2-C60 ?-olefin comonomer units different than the monomer units; optional diene units; and about 0.1 wt % to about 20 wt % metal alkenyl units, based on the weight of the copolymer, wherein the metal alkenyl units have the formula —R(A?)—, wherein R is an alkyl group containing 2 to 10 carbon atoms, and A? is an anionic group. The copolymer can further include one or more metal cations derived from the group consisting of alkali metals, alkaline earth metals, group 3-12 metals, group 13-16 metals, and combination(s) thereof. The ionomer has a glass transition temperature of ?60° C. to 5° C., and a weight average (Mw) of 50 to 5,000 kg/mol.Type: ApplicationFiled: December 8, 2021Publication date: March 14, 2024Inventors: Tzu-Pin Lin, Carlos R. Lopez-Barron, Avery R. Smith, Brian J. Rohde, Alex E. Carpenter, Matthew W. Holtcamp, Jo Ann M. Canich, John R. Hagadorn

Patent number: 5570118Abstract: An apparatus for printing a multicolor image on a sheet movable along a sheet path in a process direction. The apparatus includes a first printhead mounted at a first location along the sheet path and containing a first type ink for printing a first portion of the image on the sheet in which the first type ink has a surface tension greater than 40 dynes/cm at room temperature. The apparatus also includes a set of secondary printheads mounted along the sheet path and separated a small gap from the first printhead. The set of secondary printheads each contains a secondary type ink for printing a secondary portion of the multicolor image on the sheet, and each of the secondary type ink has a surface tension less than 40 dynes/cm at room temperature.Type: GrantFiled: August 26, 1994Date of Patent: October 29, 1996Assignee: Xerox CorporationInventors: Ivan Rezanka, John W. Lin, Gary R. Fague, Lesley P. Dudek

Patent number: 5371531Abstract: A multi-color ink-jet printer in which a first partial image is created on a recording medium, and then a second partial image is created on the same recording medium after the first partial image is substantially dried. The first partial image comprises an ink which dries at a slower rate than that of the second partial image. In one embodiment, means are provided for heating the recording medium prior to the creation of the second partial image.Type: GrantFiled: November 12, 1992Date of Patent: December 6, 1994Assignee: Xerox CorporationInventors: Ivan Rezanka, John W. Lin, Gary R. Fague, Lesley P. Dudek

Patent number: 5281261Abstract: Disclosed is an ink composition comprising an aqueous liquid vehicle and pigment particles having attached to the surfaces thereof a polymerized vinyl aromatic salt. In one embodiment, the polymeric vinyl aromatic salt is chemically grafted to the surfaces of the pigment particles; in another embodiment, the polymeric vinyl aromatic salt is adsorbed onto the surfaces of the pigment particles. Preferably, the modified pigment particles have an average particle diameter of less than about 1 micron. The ink composition is suitable for applications such as ink jet printing processes, particularly thermal ink jet printing processes. Images generated with ink compositions of the present invention are sharp, waterfast, lightfast, and of high optical density, exhibiting no feathering, and can be electrically conductive.Type: GrantFiled: August 31, 1990Date of Patent: January 25, 1994Assignee: Xerox CorporationInventor: John W. Lin

Patent number: 4628018Abstract: Disclosed are novel silylated hydroxyl squaraine compositions, novel deuterated hydroxyl squaraine derivatives, and processes for the preparation thereof. More specifically, there is disclosed a process for the preparation of photoconductive hydroxyl squaraine pigment compositions useful as visible and near infrared photoconductor materials comprising (1) effecting functionalization of the hydroxyl squaraine in an organic solvent system wherein the hydroxyl group therein are silylated, and (2) subjecting the resulting silylated products to hydrolysis enabling conversion to purified squaraine compositions, or conversion to deuterated hydroxyl squaraine derivatives. The hydroxyl squaraine compositions obtained are useful, for example, as photogenerating pigments in layered imaging members.Type: GrantFiled: August 16, 1985Date of Patent: December 9, 1986Assignee: Xerox CorporationInventors: John W. Lin, Lesley P. Dudek
