The invention discloses an intelligent blood collection device, which comprises a box body, a vacuum storage blood vessel, and a blood collection tube. There is a control panel. When in use, the blood collection tube is connected to the vacuum storage vessel and the blood collector. A capacity detection device is installed at the vacuum storage vessel, and an alarm device is also provided on the box body. The control panel controls the capacity detection device and the blood collector. An alarm device, when the required blood volume is reached, the alarm device will alarm to complete the blood collection. The device can detect the amount of blood collected and actively collect blood samples during blood collection, reducing the workload of medical staff. In addition, the device can also record and transmit patient information, one-time information collection, and prevent errors.

The present invention relates to a headlight (12) for a two-wheeler, comprising a reflector (1) that reflects light emitted from at least an LED (4), and at least holding element (16) that supports at least a circuit board (3) that is connected with at least a said LED (4). The holding element is formed outside the reflector and has a recess (2), with which the circuit board is connected in a shape locking and / or force locking manner. At least one of the recess (2) the circuit board (3), the reflector (1) and the LED (4) is designed to form an angle between 90 DEG to 130 DEG between the first main beam direction (7) of the LED (4) and the second main beam direction (8) of the reflector (1). The headlight has simple installation, good fixation of LED in the reflector. The lightful headlight is formed and reflection area covering at least 40% of the opening area of the reflector can be arranged.

The invention discloses a positioning control method, device and system for an under-activated marine crane within finite time. The method comprises the steps of (1) constructing a two-order sliding mode surface based on a kinetic model of a drivable portion of a marine crane system, and introducing a nonlinear bounded function relevant to a positioning error signal to construct a nonlinear controller; (2) receiving physical parameters of the set marine crane system; (3) receiving boom pitching angle, rope length, load tilt angle and hull roll angle due to sea wave interferences, which are acquired in real time; (4) inputting the received data to the nonlinear controller, and calculating and controlling boom pitching and rope length input force and torque; (5) driving a boom and a rope tomove to a target position within finite time, thereby eliminating residual rocking of a load.

The embodiment of the invention provides a navigation method and terminal. The method includes: generating a navigation route by a terminal according to an initial position and a target position; and according to the navigation route and a current position, driving at least two linear resonant actuators disposed at the terminal for timesharing generation of several resonance points on the terminal, with the formed guide direction matching with a current navigation direction. Through the navigation method and terminal provided by the embodiment of the invention, the linear resonant actuators disposed at the terminal are driven according to the current position and the navigation route to achieve timesharing generation of several resonance points in corresponding directions. A user can be aware of the direction of the navigation route by perceiving the guide direction of the resonance points, and can be ensured to reach a destination successfully by marching along the resonant guide direction. Frequent looking of the navigation route is not needed, and the user can concentrate on observing surrounding vehicles and obstacles, thus improving the safety during marching of the user along the navigation route.
