Publication number: 20240022019Abstract: Provided are embodiments for Universal Serial Bus (USB) male gripping connectors for USB A, USB B, and USB-C connectors. Each embodiment provides 3 to 4 times the pull-out force to keep the connectors mated to the female connector. Each embodiment is backwards compatible with existing female connectors. Embodiments connectors also include partition walls on the connector plug body's inner PCB to divide the PCB into high frequency and low frequency sections or chambers, thus allowing LED lights to protrude out for visualization while maintaining a superb near airtight EMI shielding in the high frequency section or chamber of the connector.Type: ApplicationFiled: July 3, 2023Publication date: January 18, 2024Inventor: Xiaozheng Lu

Publication number: 20230217063Abstract: Extended Digital Interface (XDI) provides systems, devices, connectors, signals, and methods to send 3D Vector and Motion based audio video serial digital signals through local systems or internet with significantly reduced bandwidth requirements and lower device costs, over longer cable runs. The XDI system has higher flexibility for connection topologies and scalability. The XDI system is much simpler to install employing the single coax cables and connectors, or internet, or Wi-Fi, which is simple and easy to work with, without introducing any signal quality losses or delays comparing to the current 2D Frame and Pixel based digital systems using multiple conductors like HDMI, DVI, DP or SDI when using the already compressed audio video content. The XDI system also provides solutions for integrating the uncompressed audio video content and Internet content into this system. These systems, devices, connectors and methods are collectively called “XDI” (Extended Digital Interface).Type: ApplicationFiled: March 12, 2023Publication date: July 6, 2023Inventors: Xiaozheng Lu, Jirong Gu

Publication number: 20220085531Abstract: This invention is an active cable or cables with a female micro USB or other connector recessed at the rear end of the HDMI plug for connecting external power when needed. The recessed connector is connected to an internal circuitry that combines this external power with the power from the source or sink device via a straight or “OR” circuits. This design is clean when no external power is needed because there're no dangling pigtails with USB plugs. When external power is needed because the source or sink devices can't provide enough current, the user can use for example widely available male micro USB to male USB cable (the standard charging cable for most Android phones and many other computer or phone accessories) or other cable to get external power, and the cable length can be selected to fit the application.Type: ApplicationFiled: November 29, 2021Publication date: March 17, 2022Inventor: Xiaozheng Lu

Patent number: 10128799Abstract: A multi-frequency tunable low-noise amplifier and a multi-frequency tuning implementation method therefor. The amplifier comprises: a system controller (13) and a micro-electro-mechanical system (MEMS) matching tuner (12) connected to the system controller (13). The system controller (13) is configured to respond to a first operation executed by a user via a user interface (15) when in a first mode, to acquire a first matching value produced on the basis of the first operation, and to output the first matching value to the MEMS matching tuner (12). The MEMS matching tuner (12) is configured to be controlled by the system controller (13) and to support the amplifier working on different frequency bands in tuning processing, thus allowing the matching value of the MEMS matching tuner (12) itself to match a current working frequency band.Type: GrantFiled: July 30, 2015Date of Patent: November 13, 2018Assignee: ZTE CorporationInventors: Xiaozheng Lu, Shaowu Shen
