Patent number: 11947198Abstract: A case for an eyewear device having a conductive interface includes a housing that receives the eyewear device. A multi-purpose interface, supported by the housing, includes at least one contact arranged to couple with the conductive interface of the eyewear device when the housing receives the eyewear device. Circuitry is coupled to the at least one contact and includes a processor that detects a connection of the conductive interface of the eyewear device to the multi-purpose interface of the case. The processor performs a charging process during a charge state of the case in which an electrical charge is provided at the multi-purpose interface of the case to the eyewear device. Data is exchanged with the eyewear device during a communication state of the case.Type: GrantFiled: March 9, 2022Date of Patent: April 2, 2024Assignee: Snap Inc.Inventors: Miran Alhaideri, Alex Bamberger, Gerald Nilles, Russell Douglas Patton, Yu Jiang Tham

Patent number: 11888402Abstract: A control system for use in a power converter having a plurality of outputs comprising a primary switching control block, a secondary control block, and a multi-output control block. The primary switching control block is coupled to control switching of a primary switch. The secondary control block is coupled to control switching of a synchronous rectifier switch. The multi-output control block is coupled to control switching of at least one pulse transfer switch coupled to one of the plurality of outputs. A request for an energy pulse is transferred to the primary switching control block to turn ON the primary switch to transfer the energy pulse to one of the plurality of outputs. The multi-output control block comprises an interface to send the request for the energy pulse and to receive an acknowledge signal to and from the secondary control block.Type: GrantFiled: November 9, 2022Date of Patent: January 30, 2024Assignee: POWER INTEGRATIONS, INC.Inventors: Antonius Jacobus Johannes Werner, Matthew David Waterson, Yuncong Alex Jiang, Roland Sylvere Saint-Pierre

Patent number: 11539298Abstract: A power converter includes a primary winding and multiple output windings to provide multiple independently controlled and regulated outputs with a common return line. The outputs are coupled to independently regulate constant current, constant voltage, or both constant current and constant voltage outputs. A secondary control block is coupled to control a synchronous rectifier switch coupled to the common return line to synchronize switching with a primary side power switch to provide complementary conduction of the primary winding and the multiple output windings. A plurality of controlled power pulse switches is coupled to the multiple output windings. A request of a power pulse from each of the outputs is transferred through the secondary control block to a primary switch control block to turn on the primary side power switch to transfer a power pulse to the multiple output windings and through controlled power pulse switches to the outputs.Type: GrantFiled: October 30, 2020Date of Patent: December 27, 2022Assignee: Power Integrations, Inc.Inventors: Antonius Jacobus Johannes Werner, Matthew David Waterson, Yuncong Alex Jiang, Roland Sylvere Saint-Pierre

Patent number: 10977024Abstract: There is provided methods and apparatuses for secure updating of firmware/software. The methods and apparatus can be enabled by making use of the Online Certificate Status Protocol (OCSP) to request the revocation status of certificates in the certificate chain. In particular, a method called ‘OCSP stapling’ can ensure the validity of the certificates or verify authenticity of the software/firmware. By virtue of features of the OCSP stapling, the user device does not need to contact CAs directly for the purpose of verifying the status of the certificates that ensure authenticity and integrity of the delivered software/firmware and thus is not required to open an extra communication channel to obtain status of certificates. This process can also reduce the burden on CAs because the CAs are neither required to keep a large volume of CRLs nor to maintain connection with user devices for which the CAs are responsible.Type: GrantFiled: June 15, 2018Date of Patent: April 13, 2021Assignee: SIERRA WIRELESS, INC.Inventor: Alex Jiang
