A weight support device includes a sensor grid that measures pressure data while a user is on the weight support device. The weight support device is connected to a computer that analyzes the pressure data and generates a virtual figure to represent the user. Based on the pressure data, the computer determines how the user moves and adjusts relative positions of segments in the virtual figure that represent various body parts corresponding to the movements of the user. The relative positions of the segments may be determined based on a kinematic model. The virtual figure is presented on a display (e.g., in a video) to illustrate how the user moved.

The application discloses an underwater robot trajectory obstacle detection method, comprising the following steps: (1) generating a feasible trajectory set; (2) generating a footprint grid map set; (3) generating a probability footprint grid map set; (4) saving the probability footprint grid map set; (5) constructing a sensor grid map set; (6) integrating sensor data; and (7) collision detection. In step (2), the footprint shape of a robot moving along a trajectory in different shapes is modeled, so that the method is suitable for robots in various shapes. In step (3), the uncertainty of the robot moving in water is considered. In step (5), the uncertainty of sensor measurement is considered.

Therefore, the method has the characteristics of high real-time performance, and can provide strong support for the safe operation of the underwater robot.

A gas turbine system includes a gas turbine engine and a gas treatment system for treating an exhaust gas, and a thermal control system to control temperatures of the exhaust gas such that the temperatures may be suitable for the gas treatment system. The thermal control system may include a tempering air control and a sensor grid control, which may cooperatively control a tempering air that may be injected into the exhaust gas. Specifically, the thermal control system may adjust the flow of tempering air by compensating for a failed sensor in a sensor grid system, using a worst case scenario assumption, to protect the gas treatment system from overheating and to allow for continuous operations of the gas turbine system without interruptions due to sensor failures.

Existing therapeutic methods lack interactivity and adaptability to individual needs. The present disclosure retrieves from a database, a hardware component design as an interactive table comprising a grid of sensor(s) to detect input(s) from a user. The detected one or more inputs from user are passed to a gaming engine connected to the hardware component. Reflex time of user is recorded, when user provides the inputs to the sensors. Reflex time is compared with predefined time Tn and at least one of following is performed based on comparison that includes incrementally changing position of object, resetting timer, increasing timer with a first delta value and moving position of object closer to initial position with a second delta value. An average response time, a progression metric and adjustments to timer are calculated. A cognitive function to assess the severity of cognitive decline of user is derived.
