    摘要： A computer implemented method for measuring a person's cognitive load comprises initially receiving 100 stroke data (FIG. 4, FIG. 5(a)) representative of hand-based strokes produced by a person 200 while performing a task. A processor 216 selects 104 a subset of the stroke data FIG. 5(c) that meets one or more predetermined stability criteria. A measure indicative of the person's cognitive load based on the subset of stroke data is determined 106. In this was the user's cognitive load in an objective, uniform and non-intrusive manner by analyzing the user's writing behavior. An analysis of all of a user's writing strokes will bias the evaluation result. The accuracy of the cognitive load measurement is increased by applying stability criteria to select the best strokes for further analysis. By disregarding unstable strokes the computation costs for determining the user's cognitive load is also improved.

    摘要： The present invention provides a method for manufacturing a photochromic article having a photochromic compound containing layer. The method includes the step of coating a casting face of at least one mold section with a photochromic host layer. The photochromic host layer is treated to minimize damage during subsequent steps, and a mold is then assembled so that it includes the mold section having the photochromic host layer. The mold is then filled with a photochromic article monomer composition and the monomer composition is subsequently cured to form a photochromic article substrate adhered to the photochromic host layer. The photochromic compound is introduced into the photochromic host layer.

    摘要： The present invention discloses a tower-shaped LED module that comprises a base, at least three LED panels mounted on the base and a bracket used to support the LED panels, wherein the LED panels are fixed on the bracket to form a pyramid. The present invention solves the traditional problem of the LED panels not secured firmly or shifting around easily. To fix the LED panels on the designed bracket, first slide each LED panel upward into sliding slots. Then insert each electrode pin of the LED panels into a corresponding pin hole in the base. Next put a screw though the base and fasten it to a supporting rod. At last solder the electrode pins of the LED panels to a printed circuit board on the bottom surface of the base. The whole assembly process is very simple and the assembled LED panels have good stability.

    摘要： This invention concerns measuring cognitive load. A word based input is produced by a person while performing a task (100). Predetermined grammatical features of the word based input are identified (104). Then, the identified grammatical features are weighted and combined to provide a measure indicating the person's cognitive load (106). The use of grammatical features represents a divergence from the known methods of providing a measure of a person's cognitive load. It is an advantage of the invention that by concentrating on the grammatical features it is able to provide an objective, non-intrusive measure of the person's cognitive load. Aspects the invention include a method, a computer system and software that are used to perform the method.
