Publication number: 20190280615Abstract: Embodiments of the present disclosure disclose a modulation method and apparatus based on a three-phase neutral point clamped inverter. The method includes outputting a control signal for controlling all the switch elements of one of the three bridge arms to be in a non-conducting state, controlling states of the switch elements of the other two bridge arms to make the three-phase neutral point clamped inverter output a single-phase signal, wherein the two bridge arms are referred to as a first single-phase bridge arm and a second single-phase bridge arm, when controlling both switch elements connected to the first input end and switch elements connected to the second input end in the first single-phase bridge arm and the second single-phase bridge arm to be in the non-conducting state, controlling two of the other switch elements in the first single-phase bridge arm and the second single-phase bridge arm to be in a conducting state to provide a freewheeling loop for an inductive current of the inverter.Type: ApplicationFiled: May 28, 2019Publication date: September 12, 2019Inventors: Siew Chun Ng, Shijun Li, Chao Zhang, Zhaomi Wu

Patent number: 10013475Abstract: Embodiments of the present invention disclose a computer program product for rebalancing partitioned data based, at least in part, on limit key extrapolation in a database and one or more characteristics of the plurality of database partitions. Responsive to a determination that an upper limit key value of the last loaded record is greater than an upper limit key value of an empty partition, the computer redefines the upper limit key value of the empty partition using an extrapolated upper limit key value that is based, at least in part, on a range of limit key values. The computer updates one or more characteristics of the database, wherein the one or more characteristics include one or both of a) an average number of records per partition, and b) an average number of unique limit key values per partition.Type: GrantFiled: July 24, 2017Date of Patent: July 3, 2018Assignee: International Business Machines CorporationInventors: Ka Chun Ng, Haakon Roberts

Patent number: 7945662Abstract: A computerized system and method for optimizing contents of a domain landing page for increased revenues for the domain name owner. A landing server tracks user interactions with the domain landing page and generates an optimized keyword data set for the domain name. The keyword data set is used for selecting the information to be displayed on the domain name page. According to one embodiment, the keywords are associated with advertiser payment values. When a link to an advertiser bidding on a particular keyword is selected, revenue generated due to the click is shared with the domain name owner. Selection of links on pop-under pages displayed with a landing page are also shared with the domain name owner. Semantic analysis of keywords and domain names allows the generation of a related keyword data set when there is insufficient number of relevant user interactions for generating the optimized keyword data set.Type: GrantFiled: October 8, 2007Date of Patent: May 17, 2011Assignee: Oversee.NetInventors: Frederick Weider Hsu, Lawrence Chun Ng

Publication number: 20070186195Abstract: A method and system for debugging using replicated logic and trigger logic is described. A representation of a circuit is compiled. One or more signals are selected for triggering and trigger logic is inserted into the circuit. A portion of the circuit is selected for replication. The selected portion of the circuit is replicated and delay logic is inserted to delay the inputs into the replicated portion of the circuit. The representation of the circuit is recompiled and programmed into a hardware device. A debugger may then be invoked. One or more of the triggering signals are selected. For each selected triggering signal, one or more states are selected to setup a trigger condition. The hardware device may then be run. The replicated portion of the circuit will be paused when the trigger condition occurs. The states of registers in the replicated portion of the circuit and the sequence of steps that led to the trigger condition may then be recorded.Type: ApplicationFiled: April 3, 2007Publication date: August 9, 2007Inventors: Chun Ng, Kenneth McElvain
