2 results about "Control posture" patented technology

The application discloses a surgical robot control method, device, equipment and medium, and is applied to the field of medical instruments. The surgical robot control method provided by the application first acquires handle control posture corresponding values at each preset time, wherein the preset times are a plurality of continuous collection times close to the current time, calculates the difference between the handle control posture corresponding values at each two adjacent times, adds up the weighted each difference value to obtain a reference value, and then determines whether to lock the surgical robot according to the relationship between the reference value and a preset value. A method capable of detecting whether a human hand leaves a surgical robot is provided, which can determine whether the human hand leaves by judging the relationship between the reference value and the preset value, so that the human hand is prevented from leaving the control handle of the surgical robot, but the surgical robot does not detect the leaving of the human hand, thereby causing a medical accident.

The invention relates to the technical field of old people tumble detection, and discloses an old people tumble real-time detection system based on attitude estimation, which comprises a control terminal and a data collection system, the data collection system is in bidirectional signal connection with the control terminal, and six daily attitudes including walking, standing, stooping, sitting down, jumping and lying down are systematically collected, so as to realize real-time detection of old people tumble. According to the data of five typical tumble scenes of forward hand use, forward knee use, backward, sideward and empty chair sitting, an extremely abundant training and judgment sample library is constructed. Omnibearing data coverage enables the system to deeply understand the slight difference between the normal activity and the tumble event in the dynamic process. Specific data modeling is carried out on scenes such as stooping, sitting down, jumping and lying down which are extremely easy to generate false alarms, and a system is effectively taught to distinguish'controlled posture change 'and'out-of-control falling process', so that the false alarm rate is substantially reduced fundamentally, and user trust decline and resource waste caused by frequent false alarms are avoided.
