Patent number: 10831518Abstract: Machine logic (for example, software) for compressing the image of an instance of a VM/container during time period(s) when the VM/container instance is inactive. A proxy is used to handle requests made to the VM/container instance during periods when it is inactive. A dependency graph is used to determine that a related set of instances of VM/containers so that: (i) when one of the VM/container instances of the related set is deactivated, then the whole set of VM/container instances are deactivated together; and/or (ii) when one of the VM/container instances of the related set is reactivated, then the whole set of VM/container instances are reactivated together.Type: GrantFiled: December 1, 2017Date of Patent: November 10, 2020Assignee: International Business Machines CorporationInventors: Christopher D. Wyble, Gregory J. Boss, Ton A. Ngo, Simeon D. Monov

Patent number: 10613907Abstract: A host system reallocates resources in a virtual computing environment by first receiving a request to reallocate a first quantity of a first resource type. Next, potential trade-off groups are evaluated and a trade-off group is selected based on the evaluation. The selected trade-off group includes a set of applications running in the virtual computing environment that can use one or more alternate resource types as a substitute for the first quantity of the first resource type. After the selection, the host system reallocates the first quantity of the first resource type from the trade-off group. This reallocation may be made from the trade-off group to either a first application running in the virtual computing environment or the host system itself. If the reallocation is to the host system, then the total quantity of the first resource type allocated to applications running in the virtual computing environment is thereby reduced.Type: GrantFiled: November 19, 2018Date of Patent: April 7, 2020Assignee: International Business Machines CorporationInventors: Gregory J. Boss, Seyyed Vahid Hashemian, Ton A. Ngo, Thomas K. Truong

Patent number: 8436936Abstract: Embodiments of the present invention include circuits and methods for calibrating position displacement in a voltage controlled actuator. In one embodiment, a calibration circuit comprises an actuator having a control terminal for receiving a programmable control voltage to set a displacement, a switch that selectively decouples said programmable voltage from said control terminal and couples a reference current to said control terminal when the control terminal is decoupled from said control voltage, a comparator that senses a voltage difference between said control voltage and said control terminal, and a timer coupled to an output of the comparator. The timer measures a time period required to increase the control terminal voltage. The capacitance of the actuator may be determined and used to calibrate the position of the actuator.Type: GrantFiled: July 12, 2012Date of Patent: May 7, 2013Assignee: Qualcomm IncorporatedInventors: Sang Ton Ngo, Thomas O'Brien, Sridhar Kotikalapoodi, M Abid Hussain

Patent number: 8344791Abstract: Embodiments of the present invention include charge pump circuits and methods. In one embodiment, a first charge pump receives a voltage and generates a first charge pump output voltage and current for supplying the power requirements of a circuit. A second charge pump is coupled in series with the first charge pump. The second charge pump generates a second charge pump output voltage and current for supplying different power requirements of the circuit. In one embodiment, the first charge pump provides a high current low voltage output to a first circuit and the second charge pump provides a low current high voltage output to a second circuit. Capacitors of the first charge pump may be external to an integrated circuit and capacitors of the second charge pump may be internal to the integrated circuit.Type: GrantFiled: August 1, 2012Date of Patent: January 1, 2013Assignee: Qualcomm IncorporatedInventors: Kenneth C Adkins, Sang Ton Ngo, M Abid Hussain, Thomas O'Brien, Sridhar Kotikalapoodi, George A Hall
