An intra-oral system is disclosed for assisting an individual in developing intra-oral muscle control and strength. The system may also be used to enable an individual having limited use of the upper extremities to control an electrical apparatus such as a wheelchair, a bed or a light fixture. The intra-oral system includes a mouthpiece having a plurality of air cells embedded therein. The air cells are configured to receive pressure applied by the tongue of an individual. Movement of the tongue over and against the air cells causes an object to be moved over a display. In one embodiment, the object is moved through an obstacle course or over a simulated track as part of a therapeutic regimen. In another embodiment, a character or icon on the display is selected and activated to manipulate an electrical apparatus. Methods for moving an electrical apparatus using a mouthpiece controlled through lingual movement are also provided.

The invention discloses an unmanned aerial vehicle obstacle avoidance method based on a binocular vision system. A binocular vision system acquires image information to obtain depth map information; with an ecological method, denoising is performed on the depth map by combining an exponential weighted moving average algorithm; an obstacle contour is extracted according to a threshold segmentationalgorithm based on region growing and fitting is performed by using a rectangular box to obtain a parallax value; an obstacle distance is calculated by the similar triangle theorem; the obtained distance is transmitted to a flight controller and is compared with a preset threshold distance, different commands are sent out, and then an unmanned aerial vehicle completes obstacle avoidance at accurate timing. According to the invention, on the basis of combination of the morphological method with the exponential weighted moving average algorithm, the denoising degree of the depth map is increased, the calculation accuracy of the distance between the unmanned aerial vehicle and the obstacle is improved, the fast visual obstacle avoidance capability of the unmanned aerial vehicle is enhanced, and the accuracy is greatly improved by being compared with the existing algorithms.

A children's instructional floor exercise apparatus for developing physical, cognitive and social skills. The apparatus has a plurality of tiles that have an anatomy indicium and an independent tile orientation indicium. When the tiles are placed in a predetermined pattern and with each tile's orientation indicia indicating the same rotational orientation, the anatomy indicia correspond to a predetermined physical movement designed to exercise a specific muscle group and develop a specific physical skill. The apparatus may be provided with written instructions describing the desired tile pattern and physical movement. Multiple apparatus may be provided in a set so as to create an obstacle course of movements, with each obstacle designed to work with and complement other obstacles in the set to provide a well-rounded exercise routine.

A compression based foundation having strategically paced padding to guard against the types of injuries most usually sustained during obstacle course racing is provided. Also provided is an energy supplement storage garment where energy supplements are within easy reach during active racing conditions.

The invention discloses an obstacle avoidance method and device, comprising: acquiring a first specific position of the obstacle if an obstacle is detected during the running of an automatic driving vehicle; determining the position of the obstacle and the vehicle body according to the first specific position The current distance; through the current distance, determine the four coordinate points of the area where the obstacle is located when the body safely avoids the obstacle; based on the four coordinate points, use the Bessel formula to calculate the obstacle avoidance path. Judging whether the driving road is smooth by detecting whether there is an obstacle, determining the current distance from the vehicle body according to the position of the obstacle, determining the coordinate point according to the current distance, and then calculating the obstacle avoidance path according to the coordinate point, the Bessel formula is compared with the existing technology The calculation method and amount of calculation in the algorithm are relatively small, so when an obstacle is detected, the computer can calculate the path around the obstacle in a short time to avoid traffic accidents.

A play apparatus has plural types of elevated equipment, namely a ropes course and a zip coaster. Both types of elevated equipment have respective user safety supports that extend along the respective equipment and receive a safety harness worn by a user. The user need not change safety harnesses to use the different types of equipment. The entry and exit locations for the elevated equipment are in a common area elevated above the ground. A third type of equipment, namely an obstacle course, is located under and above the common area.

An artificial cave has various features that resemble speleothems (e.g., stalactites, stalagmites, etc.) found in real subterranean caves. Human users may pass through the artificial cave, with each user wearing a wearable transceiver that broadcasts a signal code unique to that user. Fixed transceivers throughout the cave can detect and identify any user who is sufficiently close to that fixed transceiver. Other components of the system collect user identification information from the fixed transceivers for any of several possible purposes (e.g., identifying which user was probably responsible for inappropriate interaction with a speleothem that is adjacent to a given fixed transceiver, where all of the various user of the cave are currently located in the cave, etc.). A count of users currently in the artificial cave passageway may be maintained and used for a number of purposes. Similarly, human detectors may be employed near the system and / or in the artificial cave passage for any of several different purposes.

The invention discloses a method and device for calculating the course angle of an obstacle based on time synchronization. Wherein, the method includes: obtaining a heading angle calculation model, wherein the heading angle calculation model is obtained by training the historical data of the heading angle yaw value; sensing obstacles through a sensing device to obtain heading angle perception data; according to the heading angle The angle perception data and the heading angle calculation model are used to generate a first heading angle calculation result; and the verification operation of the synchronization time stamp is performed on the heading angle calculation result to obtain a second heading angle calculation result. The invention solves the problem that in the perception detection algorithm of the prior art, it is difficult to calculate the yaw angle of obstacles using image perception, and the result is also difficult to be accurate; it is not easy to calculate the yaw angle of obstacles accurately by using the traditional point cloud clustering algorithm , and stability cannot be guaranteed. Secondly, the calculation of the obstacle heading angle also involves the own vehicle heading angle output by the inertial navigation of the own vehicle, the calibration results of the inertial navigation and perception sensors, and the time synchronization of the sensors, which is a technical problem involving systematic problems of software, hardware and algorithms. .
