Patent number: 11855608Abstract: Systems and methods for packaging an acoustic device in an integrated circuit (IC) include walls formed on a wiring substrate. The walls have a height which is just shorter than an expected height of a solder bump on the acoustic device after solder reflow. The walls are positioned on either side of the acoustic device and a small portion lies underneath an exterior edge of the acoustic device such that a relatively small gap is formed between an upper surface of the wall and the lower surface of the acoustic device. By providing a small gap between wall and acoustic device, encroachment by an encapsulating material into a keep out zone of the acoustic device is minimized.Type: GrantFiled: August 31, 2020Date of Patent: December 26, 2023Assignee: RF360 SINGAPORE PTE. LTD.Inventors: Huan En Ku, Joo Shan Yam, Chee Kong Lee

Patent number: 11487555Abstract: A system is configured to run jobs in Kubernetes based on PBS job inputs. The system may convert a PBS input, such as in the form of a PBS job command line input and/or a PBS job script, to a Kubernetes job configuration file. A Kubernetes system may then perform a job according to the Kubernetes job configuration file. Through implementation of the conversion process, PBS users can leverage the capabilities of Kubernetes to have jobs performed without having to know how to use Kubernetes.Type: GrantFiled: June 9, 2020Date of Patent: November 1, 2022Assignee: TENCENT AMERICA LLCInventors: Matthew Chan, Chee-Kong Lee, Qiming Sun

Patent number: 11314536Abstract: The present disclosure discloses a method for obtaining optimal variational parameters of a ground state wavefunction for a Hamiltonian system. The method includes initializing a plurality of variational parameters and sending the variational parameters to a quantum computing portion to output a plurality of measurement results. The method includes transmitting the measurement results to a classical computing portion to update the plurality of variational parameters based on the plurality of measurement results and an update rule, and determining whether a measured energy satisfies a convergence rule. When the measured energy does not satisfy the convergence rule, the method includes sending the plurality of updated variational parameters to the quantum computing portion for a next iteration; and when the measured energy satisfies the convergence rule, the method includes obtaining a plurality of optimal variational parameters for the Hamiltonian system.Type: GrantFiled: July 8, 2019Date of Patent: April 26, 2022Assignee: TENCENT AMERICA LLCInventors: Chee Kong Lee, Qiming Sun

Publication number: 20170239756Abstract: Methods of making solder preforms are disclosed. A ribbon of raw material is received, and a first annular solder preform is formed by laser cutting the ribbon. The edges of the first annular solder preform can then be cleaned. The cutout section removed from the middle of the first annular solder preform can then be laser cut to form a second annular solder preform that is smaller than the first annular solder preform.Type: ApplicationFiled: February 17, 2017Publication date: August 24, 2017Inventors: Ramesh Kothandapani, SinLi Tan, Chee Kong Lee
