Abstract: The present disclosure provides an electronic wearable device. The electronic wearable device includes a first module having a first contact and a second module having a second contact. The first contact is configured to keep electrical connection with the second contact in moving with respect to each other during a wearing period.

Abstract: A mechanically and piezoelectrically anisotropic polymer article is formed from a crystallizable fluoropolymer and a nucleating agent. The polymer article may be a thin film or a fiber, for example. A crystalline phase may constitute at least approximately 50% of the polymer article. In certain examples, a fluoropolymer may include vinylidene fluoride, trifluoroethylene, chlorotrifluoroethylene, hexafluoropropylene, and vinyl fluoride. The polymer article may include up to approximately 10 wt. % of the nucleating agent. Such a polymer article is optically transparent, has an elastic modulus of at least approximately 3 GPa, and an electromechanical coupling factor (k31) of at least approximately 0.15.

Abstract: A keyboard for live streaming includes an alphanumeric part including from a plurality of keys including alphanumeric keys, modifier keys, and system commands, a plurality of scissor switches, a frame board, and a PCB; a handwriting screen including a capacitive screen and a capacitive pen configured to move on the capacitive screen for inputting letters or numbers; a function switch including a multimedia button for quickly switching between different operating systems; and an audio input assembly including an earphone port, a capacitor port, a mixer port, an output port, and a MIC port. The audio input assembly can be implemented by a live streaming sound card for stereo, volume, and sound mixing controls.

Abstract: The present disclosure directs to method, device, system for creating virtual credit card. The method may include: acquiring a subset of real-name information from a user interface of a terminal device; searching the real-name information stored in the first server with the subset of the real-name information; upon the real-name information is found in the first server, sending the real-name user information to a second server; finding whether the real-name information associates with a credit card account stored in the second server; after finding the credit card account is stored in the second server, creating, by the second server, a virtual credit card account; and storing the virtual credit card associated with the virtual credit card account in the data storage of the first server.
