Publication number: 20190350510Abstract: The present invention relates to a system and method for assessing and training the quality of attentional awareness and control of an individual. The individual's attention is monitored using a neurophysiological system such as EEG while using a computer system and display that provides signals that allow the correlation of behavioral measures of attention with neurophysiological measures. The combination of those signals is a novel, accurate and reliable system for assessing any individual's true attention capabilities.Type: ApplicationFiled: May 31, 2019Publication date: November 21, 2019Inventor: Gregory V. Simpson

Publication number: 20190350516Abstract: The present application relates to a posture display method, a device and a system for a guiding channel, and readable storage medium. The posture display method of a guiding channel includes determining an original position relation between a three-dimensional affected limb image and a virtual guiding channel displayed in a monitor according to an original position relation between the guiding channel and an affected limb and obtaining posture change data of the guiding channel. The method further includes adjusting the posture of the virtual guiding channel based on the posture change data, so as to the relative position relation between the virtual guiding channel and the three-dimensional affected limb image matches with the relative position relation between the guiding channel and the affected limb.Type: ApplicationFiled: September 17, 2018Publication date: November 21, 2019Inventors: Liping Shen, Jianli Ning, Qi Xu, Xiao Chen

Publication number: 20190350517Abstract: Systems, devices, and methods are provided for reducing a risk of unintentional falls in a subject that is at risk for falls. The device includes a sensor and a stimulator. The sensor is configured to be positioned adjacent a body portion of the user that changes orientation when the user sits and stands. The sensor is also configured to emit an activation signal when the user stands and to emit a deactivation signal when the user sits or lies down. The stimulator is in communication with the sensor and is configured to be positioned adjacent one of a calf and a lower back of the user. The stimulator is configured to vibrate at a frequency that stimulates proprioceptors of the user without inducing muscle contractions upon receipt of the activation signal from the sensor and to cease vibration upon receipt of the deactivation signal from the sensor.Type: ApplicationFiled: December 20, 2017Publication date: November 21, 2019Inventor: Vladimir Marlinski
