Abstract: A full voltage sampling circuit includes a main sampling circuit, an assist sampling circuit and a processing circuit. The main sampling circuit receives first and second input voltages, and outputs a first sampling signal according to the first and second input voltages. The first sampling signal represents a differential voltage which indicates a difference between the first input voltage and the second input voltage. The assist sampling circuit receives the first and second input voltages, and outputs a second sampling signal according to the first and second input voltages. The second sampling signal represents the differential voltage. The processing circuit is coupled to the main sampling circuit and the assist sampling circuit, and selects a larger one of currents or voltages of the first and second sampling signals as a sampling result to be outputted.

Abstract: The disclosure relates to a vertical Hopkinson pressure bar test device and a test method. The device comprises a guide cylinder, an incident bar, a transmission bar, a buffer bar and a striker, and further comprises a base; side support plates arranged vertically and upwards are provided symmetrically on two sides of the base, a horizontal first lateral support plate is provided at the top between the side support plates on the two sides, three groups of horizontal second lateral support plates are provided below the first lateral support plate sequentially between the side support plates on the two sides, and each group is provided with a clamping mechanism clamping a corresponding incident bar, transmission bar or buffer bar; the surfaces of the incident bar is pasted with a first strain gauge pad and the transmission bar is pasted with a second strain gauge pad.

Abstract: A mobile virtualization application allows a VR application user to access mobile telephone basic functions in a third-party VR application. This virtualization application may be a virtualization plugin or an independent application which virtualizes mobile functions and creates VR models. The virtualization plugin bridges between the VR application and the mobile telephone operating system allowing the user to use directly mobile telephone basic functions in the VR application. VR application users can read directly their incoming text messages, e-mail messages, application notifications, etc., in the form of VR model, and, they can use a VR application input device to control their mobile telephone basic functions in order to send messages, control a camera, etc.
