Patent number: 11804091Abstract: A cloud door lock control system identifies time varied 2D codes and images. A cloud device transmits the encryption codes of doors to be opened, the time periods for opening the doors, and the user's encryption codes to the mobile phone. The mobile phone stores these values in a memory. A mobile phone APP receives these values and encrypts them by using a specific encrypting code. The encoding way for the encoding unit is time varied. When the cloud device receives the QR code from a card reader, it is decoded and is compared with those stored in the cloud device to determine whether the door is necessary to be opened. The cloud device stores mobile phone holder's images which is transferred to the APP. The mobile phone holder's image is displayable on the mobile phone for determining whether the mobile phone holder is acceptable to pass through the door.Type: GrantFiled: February 14, 2022Date of Patent: October 31, 2023Inventor: Wai Kin Cheung

Patent number: 11783649Abstract: A cloud door lock control system with identification of time varied 2D codes is provided. A cloud device transmits the encryption codes of doors to be opened, the time periods for opening the doors, and the user's encryption codes to the handset through a communication channel and the handset stores these values in a memory. A mobile phone APP receives these values and encrypts them by using a specific encrypting code. The encoding way for the encoding unit is time varied, that is, the QR code from the encoding unit is only retained for a preset time period; after the preset time period has elapsed, the encoding unit generates another QR code. When the cloud device receives the QR code from a card reader, it is decoded. These decoded data is compared with those stored in the cloud device to determine whether the door is necessary to be opened.Type: GrantFiled: August 24, 2021Date of Patent: October 10, 2023Inventor: Wai Kin Cheung

Publication number: 20210407618Abstract: Techniques and mechanisms for a memory device to support memory repair functionality for a column of a memory array. In an embodiment, the column comprises first memory cells and second memory cells, where switch circuitry is coupled between multiple signal lines and the column. Control circuitry transitions the switch circuitry to a state which corresponds to a defective one of the first cells. The state switchedly decouples the defective cell, and an adjoining one of the first cells, each from respective ones of the signal lines. During the state, two or more of the signal lines are able to communicate each to a different respective one of the second cells. In another embodiment, the switch circuitry is transitioned to the state based on an identifier of the defective cell, and independent of whether any other cell of the column has been identified as defective.Type: ApplicationFiled: June 25, 2020Publication date: December 30, 2021Applicant: Intel CorporationInventors: Aravinda Radhakrishnan, Marcus Wing-Kin Cheung, Dinesh Somasekhar, Naga Mallika Bhandaru, Michael Nelms, Rodrigo Gonzalez Gutierrez, Kaitlyn Chen

Patent number: 11197589Abstract: A moisture retaining pocket towel includes a water retaining mechanism having an absorbing layer, a base layer and an outer layer. The water retaining mechanism is divided into a first half portion and a second half portion which is capable to be folded in half to move between a folding position and an actuating position. The moisture retaining pocket towel also has an outer rim being jointed by an upper portion rim and a lower portion rim encasing around an outer edge of the water retaining mechanism for retaining moisture. In folding position, the water retaining mechanism is folded in half and the exposure of the absorbing layer to the outside environment is minimized for retaining moisture. In addition, magnetic elements are used to retain the folding position.Type: GrantFiled: October 4, 2019Date of Patent: December 14, 2021Inventor: Man Kin Cheung

Patent number: 11121113Abstract: A bonding apparatus includes a holding element, holding element actuators, sensors, a controller and bond force adjusting actuators. In use, the holding element holds an electrical component and is moved by the holding element actuators in one or more actuating directions to contact the electrical component with a base member. The sensors measure reaction forces exerted on the holding element in response to contact between the electrical component and the base member. The controller determines bond forces to be exerted on actuating areas of the holding element during a bonding process based on the measured reaction forces, and the bond force adjusting actuators exert these bond forces on the actuating areas of the holding element during the bonding process, so as to adjust a tilt of the electrical component relative to the base member.Type: GrantFiled: January 16, 2020Date of Patent: September 14, 2021Assignee: ASM TECHNOLOGY SINGAPORE PTE LTDInventors: Ming Yeung Wan, Wai Kin Cheung, Yu Fu Cheung

Patent number: 10834571Abstract: A system and method for implementing Steering of Roaming for 5G core roaming in an Internet Packet Exchange (IPX) network. A Hypertext Transfer Protocol (HTTP)/2 Proxy is deployed in an IPX network. The HTTP/2 Proxy receives N32-f request message from a Visited Public Land Mobile Network (VPLMN). The N32-f request has an embedded N12 authorization request message or an embedded N8 registration request message. If VPLMN is a non-preferred roaming partner, the HTTP/2 Proxy appends a patch-request to N32-f request message and routes it to the Home Public Land Mobile Network (HPLMN). The patch-request causes the home Security Edge Protection Proxy (hSEPP) to replace Mobile Country Code (MCC) or Mobile Network Code (MNC) value with a predefined value that will trigger a rejection from HPLMN. The mobile device will select another VPLMN. If the VPLMN is a preferred roaming partner, the HTTP/2 Proxy routes the request without appending a patch-request.Type: GrantFiled: July 29, 2020Date of Patent: November 10, 2020Assignee: Syniverse Technologies, LLCInventors: Edward Yau, Kin Cheung, Jerry Handra, Chi Lap Seto, Jacky Luk, Kenneth Mak

Publication number: 20200107750Abstract: One embodiment provides a system for analyzing a motion. During operation, the system obtains acceleration data associated with the motion. The acceleration data can include three components corresponding to three spatially orthogonal directions. For each orthogonal direction, the system computes an amount of oscillatory energy included in the motion in the orthogonal direction based on a corresponding acceleration component. For at least one orthogonal direction, the system obtains an energy fraction factor by computing a ratio between the amount of the oscillatory energy in the orthogonal direction and a total amount of the oscillator energy. The system generates a motion-analysis output based at least on the energy fraction factor.Type: ApplicationFiled: September 30, 2019Publication date: April 9, 2020Applicant: Surge Motion Inc.Inventors: Jeffrey Tai Kin Cheung, Derek T. Cheung, Vicky L. Cheung, Gary N. Jin

Publication number: 20200110111Abstract: One embodiment provides a system for analyzing a motion of a complex system. During operation, the system obtains movement data associated with the motion over a time interval and computes, over the time interval, a distribution of energy associated with the motion based on the obtained movement data. The system further identifies energy peaks based on the distribution of the energy over the time interval, computes an energy-occurrence-frequency distribution based on the identified energy peaks over a predetermined energy range, and generates a motion-analysis result for the complex system based on the computed energy-occurrence-frequency distribution.Type: ApplicationFiled: October 3, 2019Publication date: April 9, 2020Applicant: Surge Motion Inc.Inventors: Jeffrey Tai Kin Cheung, Derek T.
