Publication number: 20220027895Abstract: The present disclosure relates to methods and a system for performing inter wallet transactions. The present disclosure provides methods and a system for enabling inter wallet transactions. The system provides an application for enabling inter wallet transactions. A plurality of wallets is registered with the application and a plurality of users associated with one or more of the plurality of wallets is also registered with the application. An intermediate account is created in the application for each user. When a first user associated with a first wallet among the plurality of wallets initiates a transaction to be made to a second user associated with a second wallet among the plurality of wallets, the application debits an amount to the intermediate account in the application and transfers the amount to the second user associated with the second wallet. Therefore, seamless transactions can be made between any wallets registered with the system.Type: ApplicationFiled: July 24, 2020Publication date: January 27, 2022Inventors: Yuanbo Zhu, Hang Nga Nguyen, Zhi Min Ong, Linghan Zhang, Ying Jie Lim, Li Wencheng

Publication number: 20060080831Abstract: A method for delivering a geometric type stress relief element to a terminated electrical cable is provided. The cable contains a conductor surrounded by at least one coaxial layer of insulator, semiconductor, grounded wires and cable jacket. First, the terminated cable is tapered to expose a portion of the conductor so as to protrude beyond the insulation, which protrudes beyond semiconductor, which protrudes beyond the conductive wires. A geometric stress cone is preloaded onto a cold shrink tube. The terminated, tapered cable is inserted into the cold shrink tube. The cold shrink tube is removed and the geometric stress cone collapses onto the tapered cable. The cable is rated for supplying high voltage.Type: ApplicationFiled: October 14, 2004Publication date: April 20, 2006Inventors: Nga Nguyen, Todd Richardson, William Taylor, Ming Zhang
