Abstract: The present invention discloses an implantable nerve stimulator system. An extracorporeal energy controller of the implantable nerve stimulator system transmits electrical energy to an implantable neurostimulator through radio frequency and communicates with it, including: an input device through which the extracorporeal energy controller receives information; an antenna module that is RF coupling with a stimulator antenna of the implantable neurostimulator; a display device for displaying data, instructions, and the input information; a storage unit storing running programs, input information, and data; and a control unit respectively connected to the input device, the antenna module, and a display device to control the operation of the entire extracorporeal energy controller. The neural stimulation system of the present invention can avoid treatment failure caused by short-term interruption of communication and provide stable power supply to the implantable neurostimulator.

Abstract: A dual axis solar tracker is provided. The dual axis solar tracker includes a moving platform, a fixed platform, a serial chain, a parallel chain and a driving device. The moving platform is supported by the serial chain and driven by the parallel chain, forming a parallel tracking mechanism. The driving device is configured to drive the parallel chain to motion so as to drive the moving platform to rotate around vertical and horizontal axes. The dual axis solar tracker of the present disclosure has a larger workspace, a better tracking performance and advantages of high rigidity, low energy consumption, small driving torque and low inertia, etc.
