  • Hair Cleansing and Conditioning Composition
    Publication number: 20200129398
    Abstract: The present invention provides a hair cleansing conditioner composition containing a) 0.01 w/w %-20 w/w % of a cationic surfactant; b) 0.01 w/w %-20 w/w % of a polyglyceryl ester; and c) 0.01 w/w %-15 w/w %, of at least one fatty alcohol. A method of cleansing hair is also described.

  • Method and system for controlling a doubly-fed induction machine
    Patent number: 8476871
    Abstract: The present invention relates to a method and system for controlling a doubly-fed induction machine. In operation a rotor current vector is processed with a rotor position estimate vector. A scalar error quantity is the determined in dependence upon a stator current vector and the processed rotor current vector. The scalar error quantity is integrated and an estimate of the rotor angular frequency is determined in dependence upon the integrated scalar error quantity. To obtain a rotor position estimate, the estimate of the rotor angular frequency is integrated and a rotor position estimate vector is determined in dependence upon the rotor position estimate. The rotor position estimate vector is then provided for processing the rotor current vector. As output signals a signal indicative of the rotor position estimate vector and a signal indicative of the estimate of the rotor angular frequency are provided for controlling the doubly-fed induction machine.
