Patent number: 11645248Abstract: Data migration of large volumes can require large memory requirements and knowledge of complicated data migration tools. In one example, a data migration application may be initiated and a data volume may be identified to migrate from a source database to a destination database. The process may include deleting data currently stored in a staging table of the destination database, and transmitting the data volume from the source database to the staging table stored in the destination database.Type: GrantFiled: April 5, 2021Date of Patent: May 9, 2023Assignee: International Business Machines CorporationInventors: Rob K. Johnson, Kenneth C. Barnett

Patent number: 8421541Abstract: Techniques for designing a highly differential single-ended-to-differential converter for use in, e.g., communications receivers. In an exemplary embodiment, an auxiliary current path including cascomp transistors is coupled to a main current path including input transistors and cascode transistors. The transistors are biased such that inter-modulation products generated by the auxiliary current path cancel out inter-modulation products generated by the main current path. In another exemplary embodiment, current source transistors for the main current path are adaptively biased depending on the level of the input signal received. In an exemplary embodiment, the techniques may be applied to designing a converter for interfacing a single-ended low-noise amplifier (LNA) output voltage with a differential mixer input in a communications receiver.Type: GrantFiled: October 26, 2009Date of Patent: April 16, 2013Assignee: QUALCOMM IncorporatedInventors: Susanta Sengupta, Kenneth C.

Patent number: 8098110Abstract: A phase locked loop apparatus includes an oscillator, a variable capacitance device, a selectable capacitance device, and a capacitance controller that is configured to provide a control signal to the selectable capacitance device. The selectable capacitance device is connected to the oscillator and is responsive to the control signal such that the selectable capacitance device has a first capacitance at a first control signal value and a second capacitance at a second control signal value. The capacitance controller only selects either the first capacitance or the second capacitance by providing a control signal that has the first control signal value to select the first capacitance and having the second control signal value to select the second capacitance.Type: GrantFiled: November 20, 2009Date of Patent: January 17, 2012Assignee: QUALCOMM IncorporatedInventors: Bo Yang, Harish S. Muthali, Kenneth C. Barnett

Patent number: 7888983Abstract: Techniques for generating a signal having a predetermined duty cycle. In an exemplary embodiment, a first counter is configured to count a first number of cycles of an oscillator signal, and a second counter is configured to count a second number of cycles of the oscillator signal, with the second number being greater than the first number. The output of the second counter is used to reset the first and second counters, while the outputs of the first and second counters further drive a toggle latch for generating the signal having predetermined duty cycle. Further aspects include techniques for accommodating odd and even values for the second number.Type: GrantFiled: September 11, 2009Date of Patent: February 15, 2011Assignee: QUALCOMM IncorporatedInventors: Kun Zhang, Kenneth C. Barnett

Patent number: 5945985Abstract: An interactive multimedia geographic system is disclosed which incorporates an animated three-dimensional solid model of a world globe and utilizes video, sound, graphics, images and numerical presentations for perspective display of detailed maps of the world or portions of the maps. The system is capable of generating desired regional, global, political, and other maps detailing information on various geographic related features, such as demographic, cartographic, topographic, and geomagnetic features of the world. The system is coordinated with a physical globe which highlights the region of interest, and maintains a sense of perspective and relations among geographical regions as the display of the world model changes to reveal further details.Type: GrantFiled: May 20, 1996Date of Patent: August 31, 1999Assignee: Technology International, Inc.Inventors: Shane P. Babin, Kenneth C. Barnett, Abdo A. Husseiny
