Abstract: Disclosed is a passive wireless device for microfluidic detection of multi-level droplets. A primary inductor channel and a secondary inductor channel each comprise two layers of inductance coils, and the inductance coils of the primary inductor channel and the secondary inductor channel are alternately arranged in each layer. A double-resonance circuit is formed after a liquid conductive material is injected. A first part of a detection channel is disposed between a primary capacitor channel, and a second part of a detection channel is disposed between a secondary capacitor channel. A reading device is used to read a resonant frequency of the double-resonance circuit, and perform detection according to the resonant frequency to obtain information of a corresponding first droplet group and/or second droplet group.

Abstract: A dual-filter-based transfer alignment method under dynamic deformation. A dynamic deformation angle generated under dynamic deformation and a coupling angle between dynamic deformation and body motion will reduce the accuracy of transfer alignment; and a transfer alignment filter is divided into two parts, the first part estimates a bending deformation angle and the coupling angle, and uses an attitude matching method, and the second part estimates a dynamic lever arm, and uses a “speed plus angular speed” matching method.

Abstract: The present invention discloses an embedded urban design scene emulation method and system. The method includes the following steps: constructing a status quo urban three-dimensional model scene according to collected oblique photography data; loading a three-dimensional model of urban design to a scene, and extracting geometric attributes for generation of buildings; unifying a space coordinate system of models and scenes, and automatically determining a space matching degree by taking buildings as a basic unit, and marking matched buildings with Y and mismatched buildings with N for distinction; for a region with the buildings marked with N, performing a local flattening operation in a three-dimensional model scene of oblique photography to flatten stereo data; for a region with the buildings marked with Y, performing real-time space editing in the three-dimensional model of urban design to hide the marked buildings; and opening two sets of processed space data to implement mosaic display. The present invention can conveniently embed a three-dimensional model of urban design into a status quo three-dimensional model of oblique photography for scene emulation, and provides technical and method supports for digital presentation and management of urban design achievements.

Abstract: A wearable upper limb rehabilitation training robot with precise force control includes a wearable belt, a multi-degree-of-freedom robot arm, and a control box. The robot is worn on the waist of a person by using a belt, and driven by active actuators, to implement active and passive rehabilitation training in such degrees of freedom as adduction/abduction/anteflexion/extension of left and right shoulder joints and anteflexion/extension of left and right elbow joints. In addition, a force/torque sensor is mounted on a tip of the robot arm, to obtain a force between the tip of the robot arm and the human hand during rehabilitation training as a feedback signal, to adjust an operating state of the robot, thereby realizing the precise force control during the rehabilitation training.

Abstract: A robot system for active and passive upper limb rehabilitation training based on a force feedback technology includes a robot body and an active and passive training host computer system. Active and passive rehabilitation training may be performed at degrees of freedom such as adduction/abduction and flexion/extension of left and right shoulder joints, and flexion/extension of left and right elbow joints according to a condition of a patient. In a passive rehabilitation training mode, the robot body drives the upper limb of the patient to move according to a track specified by the host computer, to gradually restore a basic motion function of the upper limb. In an active rehabilitation training mode, the patient holds the tail ends of the robot body with both hands to interact with a rehabilitation training scene, and can feel real and accurate force feedback.

Abstract: An ultra-low-power mode control circuit for a power converter includes four modules: a level shift circuit, a start circuit, a static clamp circuit, and a control circuit. When a chip is powered on and a core voltage has not been established, the control circuit firstly starts a power source built-in clock to support operation of the power converter. When the core voltage is established, the control circuit determines whether to switch to an external clock according to a level of a mode selection signal. After the core voltage is powered down, the control circuit automatically wakes up the built-in clock to work.
