Patent number: 10419943Abstract: An overlay of millimeter wave (mmWave)-capable cells are added to a citizens broadband radio service (CBRS) network to provide coverage in a next generation fixed wireless (NGFW) network. The availability of mmWave spectrum, with limited reach, can be utilized as a wireless backhaul for subsequent hops. In one aspect, integrated access front-haul nodes (IAFHNs) that are utilized for mmWave transmissions at a second (and/or subsequent) hop can be deployed with self aligning receivers. Further, the IAFHNs can facilitate adaptive resource allocation scheduling in an integrated access and backhaul (IAB) chain. In addition, an interface between macro access points can be enhanced to enable the adaptive resource allocation on the IAB chain. In one aspect, a fixed user equipment (UE) can be configured with dual connectivity (DC) and a network operator can offer different tiers of services based on a location of the UE.Type: GrantFiled: June 15, 2018Date of Patent: September 17, 2019Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Tony Wah-Tung Wong, Spyridon Kapoulas, Rajeev Jayaram

Publication number: 20190199757Abstract: Concepts and technologies provided herein can provide high-definition voice for fixed mobile convergence on mobile and wireline networks. A processor executing instructions can detect a call request associated with a called telephone number to setup a call session, where the call request is initiated from a calling device associated with an originating network. The processor can determine a call path for the call session from the originating network to a receiving network. The processor can create a fixed mobile convergence request to alert an electronic number mapping system of the call path for the call session from the originating network to the receiving network. The electronic number mapping system can provide a network presence map identifying a plurality of call receiving devices associated with the called telephone number that are available to participate in the call session via the receiving network.Type: ApplicationFiled: December 21, 2017Publication date: June 27, 2019Applicant: AT&T Intellectual Property I, L.P.Inventors: Tony Wah-Tung Wong, Gregory Johnson, Elaine Kung

Publication number: 20170085085Abstract: Voltage fluctuations in a supply network are intended to be reduced efficiently and cost-effectively. According to the method, a current flowing into a load is measured and a corresponding current measurement signal is obtained. The voltage fluctuations are reduced with the aid of a TCR, which constitutes a thyristor-controlled reactance, and a VSC, which constitutes a voltage source converter. The current measurement signal or a corresponding variable is divided into a first portion and a second portion depending on a predefined absolute limit value. The TCR is controlled on the basis of the first portion and the VSC is controlled on the basis of the second portion. Alternatively, the TCR can be controlled with the load current measurement signal and the VSC can be controlled with a sum of the load current measurement signal and a TCR current measurement signal.Type: ApplicationFiled: April 9, 2015Publication date: March 23, 2017Inventors: MARTIN PIESCHEL, JONAS PINKWART, KWOK TUNG WONG

Patent number: 8544840Abstract: An automatic document feeder with a drive system that can efficiently handle double-side scanning and accommodate more than one timing sequence for sequentially picking individual sheets from a stack using only two motors—a pick motor and a media motor. The automatic document feeder includes a pickup unit with a pick roller, a set of de-skew rollers, a main media path configured to guide a media sheet from the pickup unit to a scanning region and from the scanning region to an output tray, and a switch-back path configured to guide the media sheet back into the main media path. The drive system is operable to provide a high-speed picking mode and a delayed picking mode. In the high-speed picking mode, the pickup unit is driven by the pick motor to pull a subsequent media sheet from a stack of media sheet as soon as a previously pulled media sheet has passed the pick roller.Type: GrantFiled: April 30, 2007Date of Patent: October 1, 2013Assignee: Hewlett-Packard Development Company, L.P.Inventors: Keng Leong Ng, Thaddie Natalaray, Kyi Thu Maung, Toh Tung Wong, Wayne E Foote, Jeffrey C Madsen

Patent number: 8047151Abstract: A system and method for configuring and supporting mooring lines deployed on offshore structures, e.g. Spar-type platform, are provided with recessed portions that are located around the splash/ice zones for “cutting” through waves. An offshore structure may be provided with a chain tensioning mechanism that applies a desired tension to a hull chain and mooring line during mooring. Upon mooring the offshore structure, a chain lock mechanism maintains the tension in the hull chain and mooring line, while the chain tensioning mechanism releases a portion of the hull chain which is to be stored in a chain housing which is fully submerged underwater. This way, the recessed portions of the offshore structure around the splash/ice zones would be substantially free of the hull chains. Additionally, a disconnect mechanism may be provided to allow quick and safe disconnection of the offshore structure from the mooring position.Type: GrantFiled: July 29, 2009Date of Patent: November 1, 2011Assignees: Keppel Offshore & Marine Technology Centre Pte Ltd, Offshore Technology Development Pte LtdInventors: Kok Seng Foo, Asbjorn Mortensen, Rune Henriksen, Chai Wah Koh, Toh Tung Wong
