Abstract: A system and a method for event recognition comprising the steps of reading a signal transmitted over a defined space, wherein the signal reading includes signal information arranged to be affected by an event within the defined space; processing the signal information with a matching engine, wherein the engine is arranged to match the signal information with one or more associated event labels to recognize the event within the defined space.

Abstract: A semiaromatic copolyamide resin and a polyamide molding composition consisting of the same are provided, consisting of following repeat units: (A) 26-80 mol % of units derived from para-amino benzoic acid; (B) 4-70 mol % of units derived from 11-aminoundecanoic acid or undecanolactam, and 0-70 mol % of units derived from another amino acids having 6 to 36 carbon atoms or units consisting of a lactam having 6-36 carbon atoms; (C) 0-37 mol % of units derived from a diamine unit having 4 to 36 carbon atoms; and (D) 0-37 mol % of units derived from a diacid unit having 6 to 36 carbon atoms; wherein, (A)+(B)+(C)+(D)=100 mol %; and molar contents of the units derived from para-amino benzoic acid and those derived from 11-aminoundecanoic acid or undecanolactam are not equal to 50 mol % simultaneously.

Abstract: The present invention discloses a semiaromatic polyamide resin, a preparation method thereof, and a polyamide molding composition consisting of the same, which consists of following components: (A) 20 to 95 wt % of a PA10T homopolymer derived from 1,10-decanediamine and terephthalic acid; and (B) 5 to 80 wt % of a PA6T homopolymer derived from 1,6-hexanediamine and terephthalic acid. Particularly, (A)+(B)=100 wt %. In the present invention, by adding a certain amount of the PA10T homopolymer into the PA6T homopolymer, a melting point of the PA6T homopolymer can be significantly decreased to be below a decomposition temperature thereof, and thereby a processability of the PA6T homopolymer is improved. The prepared semiaromatic polyamide resin has a decreased melting point, and may be processed normally. The polyamide molding composition consisting of the semiaromatic polyamide resin has a good processability, and has excellent surface properties.
