The invention relates to a rotary spindle vortex spinning method and relates to the technical field of textile processing. A static spindle in a spinning apparatus of a vortex flow spinner is changedinto a rotary spindle, the method for performing vortex wrapping to form yarns by adopting the static spindle in the traditional spinner is changed, fiber fringing main body torsion and hold type twisting and outer fiber vortex wrapping are integrated actually, and yarn forming of performing external transfer twisting and holding on internal main body fibers and performing tight wrapping on outerfibers can be realized. After the formed yarns pass through a C-shaped bend, the yarn bodies rotate along a direction opposite to a surface fiber wrapping direction, the wrapping tightness of the fibers on the surfaces of the yarns is cured, fibers inside the deformed yarns are twisted, the cohesive force and spirality of the fibers inside the yarns are enhanced, and soft and high-strength smoothyarns are finally formed. According to the spinning method disclosed by the invention, the twist yarn forming process and mechanism of the yarns are simplified, the strength, softness and smooth finish of the formed yarns are improved, and the range of vortex spinning raw materials and the limit of the spun yarn count can be extended.

A system and method provides noninvasive mental state diagnostics and brain stimulation via consensual transcranial stimulation. The method utilizes face recognition associated with known physiologic measures to identify an emotional state- of-mind of a human subject and then provides or at least suggests a transcranial stimulation treatment for enhancing mental focus or for alleviating discomfort or anxiety by inducing a feeling of well-being. An example system arrangement utilizes a camera to scan a subject's facial expressions and, if the subject desires, provides a transcranial stimulation to the subject based upon an analysis of the facial expression. In one example environment, the system is used in the office or other workplace. In another example environment, the system is used in conjunction with a vehicle seat, such as for example a seat in a car, train, aircraft or other vehicle. All or parts of the system may be incorporated within or near a seat and includes at least a camera for obtaining images of the subject's face, body sensors that measure physiologic characteristics, a user interface device which may include a display and touch controls for input, and a hardware processor for analyzing the scan of the subject's facial expression and operating the user interface device.
