The invention relates to a vehicle environment sensing system and method based on an unmanned plane, and the system and method are used for quickly acquiring the road environment information around a vehicle. The sensing system comprises the unmanned plane and an earth station, the unmanned plane id connected with the vehicle through a mooring rope, the road surface is shot by the unmanned plane, and a video image is transmitted to the earth station; the earth station is arranged in the target vehicle, the earth station can process the video image to obtain the vehicle environment information, and the earth station also can calculate the flight control parameter and send the parameter to the unmanned plane to make the unmanned plane and the vehicle move together. The sensing method is based on the sensing system, the unmanned plane takes off and hovers above the vehicle, the unmanned plane establishes a communication for sensing the environment and transmits the video image to the earth station, the earth station processes the video image, calculates the vehicle environment information and transmits the information to the vehicle, and the earth station calculates the flight control parameter and transmits the parameter to the unmanned plane. According to the invention, the system can perform the wide area observation in the direction vertical to the vehicle plane direction, the coverage is wide, the road environment information around the target vehicle can be easily sensed, and the distance between the objects in the image can be precisely calculated.

Wireless sensor-based detecting and positioning method for pollution source close to impervious boundary

The invention relates to a wireless sensor-based detecting and positioning method for a pollution source close to the impervious boundary. The method comprises the following steps: n sensor nodes are randomly distributed at areas close to the impervious boundary to be detected and are connected with a terminal node in an RF (Radio Frequency) manner; the terminal node is in wireless connection with a gateway which is connected with a PC through a serial port line; a management software is installed in the PC; the sensors detect whether the pollution source exists or not through a detection module in the management software; the nodes detecting out the pollution source are saved and compared with a steady-state concentration difference value Delta c in an analyzing module at a pollution source diffusion stage and then enter a positioning module 1 or 2, so as to obtain the position coordinates of the pollution source detected by the corresponding nodes; and finally, the position coordinates of the pollution source detected by all the nodes are averaged to serve as the position coordinate of the pollution source. The method provided by the invention has the characteristics of strong operability, high accuracy and low cost, and is tally with the practical pollution discharge situation.

Entrepreneurship potential scene simulation evaluation system and evaluation method

The invention discloses an entrepreneurship potential scene simulation evaluation system and an evaluation method, and belongs to the technical field of entrepreneurship capacity evaluation. The system comprises a scene simulation test room, entrepreneurship potential scene simulation evaluation system software and a microcomputer. When the entrepreneurship potential scene simulation evaluation system software operates, typical entrepreneurship thinking and psychological activities of a subject are reflected through operation of reaction keys on the basis of visual stimulation, output by the screen of the microcomputer, of the subject. The microcomputer evaluates and calculates factors of entrepreneurship potential in a quantitative mode according to reaction time and the failure rate of operation of the subject, and judges whether the subject has the entrepreneurship potential which a successful entrepreneur owns. The system and the method can provide a scientific basis for identification and development of entrepreneurship talents, have significant theoretical direction meanings and practical popularization value for improving the entrepreneurial success rate and entrepreneurial performance and promoting deepening and development of entrepreneurial economy, and meanwhile provide a new concept for objective and precise identification and evaluation of various brain functions and career potential or competence.

Apparatus and method to determine functional lung characteristics

An apparatus for determining functional lung characteristics of a patient includes an electrical impedance tomography (EIT) imaging device adapted to record the impedance distribution within a plane of the thorax of the patient. The EIT imaging device includes a control and analysis unit for performing the impedance measurement and deriving the impedance distribution within the plane of the thorax. The control and analysis unit automatically performs steps including determining a global impedance change, defined as the impedance change with respect to an earlier measured reference impedance distribution integrated over the electrode plane, and recording the global impedance change curve as a function of time, performing breath detection in order to identify a breathing cycle, subdividing each breathing cycle to define a plurality of intratidal intervals, subdividing an EIT image from each interval into a plurality of regions of interest and calculating for each region of interest the ratio of the integrated impedance change within this region of interest to the global impedance change of this EIT image, for each intratidal interval presenting indications of the ratios determined for the regions of interest to provide an intratidal gas distribution representation for each interval.

Multi-channel electrical stimulation system and stimulation method

An existing commercialized prosthetic hand system has developed a more attractive appearance and enough driving degrees of freedom, and can meet the daily life of amputated patients, however, the existing commercialized prosthetic hand system generally lacks an effective sensory feedback function, and prosthetic hand equipment cannot be incorporated into proprioceptive mapping. On one hand, a disabled patient is easy to generate a control fatigue feeling and a psychological conflict emotion in the use process, so that the phenomenon that the use frequency of dexterous hand equipment is greatly reduced or the dexterous hand equipment is abandoned is caused; and on the other hand, the deficiency of multiple sensory feedback such as pressure sensation and position sensation also causes that the patient cannot make fine actions such as pinching, grasping and touching in real time, which becomes a key technical link urgently needing to be solved in the current artificial hand research field. The invention provides a multi-channel electrical stimulation system and stimulation method for dexterous hand touch sense and position sense feedback, which can output multi-channel portable electrical stimulation equipment with high real-time performance and wide frequency, and specially designs a multi-channel gating circuit for expanding the number of constant voltage source stimulation channels. The contradiction between the oversize circuit size and the portability requirement of an artificial hand system is solved; meanwhile, a current monitoring circuit is designed in a matched mode, and the current gathering phenomenon caused by skin impedance change or electrode falling is prevented.
