A new method, system and apparatus is provided that enables muscle signals that correspond to muscle contractions to be mapped to one or more functions of an electronic device such as a prosthetic device or gaming apparatus. Muscle signals are classified in real-time from self-selected intentional movements. A self-training protocol allows users to select and label their own muscle contractions, and is operable to automatically determine the discernible and repeatable muscle signals generated by the user. A visual display means is used to provide visual feedback to users illustrating the responsiveness of the system to muscle signals generated by the user.

It is intended to provide an evaluation method and a screening method capable of eliminating a substance that disturbs in vivo kinetics in an individual and capable of simply and easily searching a substance having an action of activating / suppressing an innate immune mechanism without being affected by LPS derived from bacteria, which can be contaminated during the search, as well as a drug and a food for activating / suppressing the innate immune mechanism, and methods of producing the same. The present invention provides a method of evaluating or screening the substance having the action of activating / suppressing the innate immune mechanism using a muscular contraction of an organism having the innate immune mechanism as an indicator, and methods of producing the drug and the food for activating / suppressing the innate immune mechanism. Also, an innate immunity activator and the food having the action of activating the innate immune mechanism containing the substance having the action of contracting the muscle of the organism having the innate immune mechanism, and an innate immunity suppressor and the food having the action of suppressing the innate immunity containing the substance having the action of suppressing the contraction of the muscle of the organism having the innate immune mechanism are provided.

The present invention relates to a device which enables a selective therapeutic exercise regimen by providing a tensioning mechanism attached to a rotatable platform along with the unique feature is where two trollies on curved rails operating on X-axis and Y-axis when pressure is applied, will work in unison to travel in any desired direction creating a unique spherically rotational reaction. The platform will react to changes in the operator's weight shifts and center of gravity placed upon it. When this novel multi-rotational aspect of the platform responds to subtle changes in the operator's center of gravity, movement of the platform will occur. These changes trigger muscular contractions around the joints of the operator responding to the rotation of the platform while the tensioning mechanism allows for selective resistance to the free movement of the platform enabling selective exercise and therapy routines for various muscle groups. Additionally, the present Multi-Planar Rotational Platform and Suspension Device offers easy scalability and uniform or non-uniform scaling in the X-axis, the Y-axis and / or the Z-axis.

The invention provides a method for evaluating the steering control efficiency of a vehicle driver. The method comprises the following steps of: installing a steering sensor on a steering column of a vehicle to measure a steering force from the driver, attaching a muscle electrode to the shoulder muscle of the driver to collect a myoelectric signal of the shoulder muscle group of the driver, and establishing estimation equations of effective steering force and total steering force during steering control of the driver by regression analysis in combination with a model of relationship between the driver myoelectric signal and the muscular contraction force. The method achieves the purpose of evaluating the steering control efficiency of the driver and provides a theoretical basis for evaluating the steering comfort of the driver and the performance of the steering system. The method is suitable for the steering control of various vehicles and can be widely applied to the evaluation of driving comfort and steering system performance.
