The digital probe instrument is used for measure the microwave impedance of electronic circuit, which request both the precision and resolution of 3d displacement of the probe at the level of 1~2μm.As there are a lot of the points to be measured, it is a high labor intensity and low efficient work when person moving and positioning the right position through high magnification microscopy only by eyes, as well as some points that should be measured are easily ignored. A double-3d displacement sliding table consists of grating digital system is proposed in the paper, which could solve the problems successfully.

At present the hole digging pile is excavated in artificial by digging the hole .This method usually works in low efficiency, high labor intensity of workers and poor security situations. So through the analysis of the artificial excavating pile 's requirement, there is necessary to create a new structural of a machine with the help of pneumatic conveying system to dump soil. In this paper the authors introduce a hand-held excavator which has the above structure in excavating. This machine adopted a motor as a power device, used secondary gear reducer to achieve speed-down, and drill bit was driven by the transmission shaft to complete the excavation. The machine has the digging ability of 240mm excavation pit diameter, simple structure design. It can meet one man operation requirements, and can be carried easily.

Due to the importance of offline consumer behavior, more and more people had begun to study consumer behavior in store. In offline consumer behavior research, the application of video analysis technology was the most direct and convenient. Recognizing human posture was a key technology in video analysis. The OpenPose algorithm was one of the advantageous technologies that could accurately recognize multi-person poses in different environments in real time, so we used it innovatively to study consumer behavior in store. We hope to develop the potential of this application in the research of consumer behavior in store in the footwear retail industry by the technical advantages of the OpenPose algorithm. In our study, we first used an OpenPose algorithm to estimate multi-person pose and detection behavior, and then processed and recognized the videos collected in the store. We collected a week's surveillance video of a Red Dragonfly offline store from July 10 to July 16, 2020 in China. The specific process was to calibrate the area in the selected camera screen, then the algorithm performs identification and detection, and finally output in-store consumption Behavioral data. Our research results not only verified the feasibility of this application in offline retailing stores, but the data results also indicated that consumers tend to enter the store from the right, staying concentrated in the middle and back of the store. These results may be affected by the store space, product display, and staff guidance and reception.

The conventional pacing systems consist of a small size-battery, an electronic circuit and leads. Despite improvements in diagnostic and therapeutic features, transvenous leads remain the weakest link of the pacing system. Nowadays, two types of leadless cardiac pacemaker (LCP) exist leading stimulation from the right ventricle (RV) apex or low septum at the desired lower rate, with rate responsive algorithms. We report our experience with an LCP implant in a severely obese patient and demonstrate the feasibility of the procedure and the excellent telemetric (conductive) communication between the LCP and the programmer despite the critical mass of the patient.
