Publication number: 20240291398Abstract: A MAP architecture includes a low-voltage digital module, a low-voltage analog module, and one or more high-voltage analog modules. The low-voltage digital module is communicatively connected to the digital signal bus for implementing digital functions, the low-voltage analog module is communicatively connected to the low-voltage digital module and the digital signal bus for implementing low-voltage analog functions, and the high-voltage analog modules are communicatively connected to one or more of the low-voltage digital module, the digital signal bus, and the low-voltage analog module for implementing high-voltage analog functions. The present disclosed MAP architecture integrates low-voltage and high-voltage analog functions required for applications such as energy-saving power control. These functions include power input, mixed-signal processing, and load driving. The integration of these functions allows users to reduce the construction of peripheral hardware analog circuits as much as possible.Type: ApplicationFiled: February 23, 2024Publication date: August 29, 2024Applicant: HUADA SEMICONDUCTOR CO., LTD.Inventors: Xucheng WANG, Wei XIE, Bin LIU, Jingwei XU, Kai QIAO, Wei XU, Jian HE, Dawei LI, Yuxiao GONG, Kebin LI, Wei WU

Patent number: 11877041Abstract: An image sensor including a planar sensor array, a lens configured to form an optical image on the planar sensor array and characterized by a locus of focal points on a curved surface, and a cover glass with multiple thickness levels or multiple cover glasses of different sizes. The one or more cover glasses are configured to shift the locus of focal points for large field angles, such that there are multiple intersections between the planar sensor array and the locus of focal points for a large FOV, and thus multiple zones with best focus on the planar sensor array.Type: GrantFiled: July 23, 2020Date of Patent: January 16, 2024Assignee: QUALCOMM IncorporatedInventors: Russell Gruhlke, Ravindra Vaman Shenoy, Jon Lasiter, Donald William Kidwell, Khurshid Syed Alam, Kebin Li

Patent number: 11867320Abstract: In a polymeric microfluidic valve, an adhesion control surface with discrete micro- or nano-scale structured surfaces are separated by fluid filled voids at an interface between an elastomeric membrane seals against a substrate layer. The structured surfaces reduce adhesion between the membrane layer and the substrate layer and prevent permanent bonding, while at the same time providing a good balance of adhesion at the valve seat to provide a sealing engagement. Microstructured adhesion control surfaces on and around valve bodies permit opening the valve, by reducing contact surface area.Type: GrantFiled: March 4, 2019Date of Patent: January 9, 2024Assignee: National Research Council of CanadaInventors: Kebin Li, Keith Morton, Teodor Veres

Patent number: 10353210Abstract: Disclosed herein are techniques for dynamically forming an optical component that automatically aligns with and changes positions with a scanning light beam to modify the wave front of the scanning light beam, such as collimating the scanning light beam. More specifically, a patterning beam that aligns with the scanning light beam may be scanned together with the scanning light beam to form the self-aligning and travelling optical component in an electro-optic material layer that is connected in serial with a photoconductive material layer to a voltage source, where the patterning beam optically modulates the impedance of the photoconductive material layer and therefore an electric field within the electro-optic material layer, the modulated electric field causing localized changes of refractive index in the electro-optic material layer to form the self-aligning and travelling optical component.Type: GrantFiled: February 9, 2017Date of Patent: July 16, 2019Assignee: QUALCOMM IncorporatedInventors: John Wyrwas, Robert Holman, Russell Gruhlke, Khurshid Alam, Kebin Li
