Abstract: A method for conditioning indoor air comprises the steps of obtaining a detecting value of any one of detecting indexes of the indoor air; determining whether the detecting value is within a preset range; if yes, executing a next operation; if no, determining whether the detecting value is greater than an upper limit of the preset range; if yes, executing a first preset operation to, make the detecting value return to the preset range; and if no, executing a second preset operation to make the detecting value return to the preset range. The method for conditioning indoor air provided in the present application is capable of detecting the indoor air automatically and controlling corresponding electric appliances to work according to the detecting value automatically, which makes the air return to a reasonable range and improves the intelligence degree of the electric appliances.

Abstract: The present invention provides means of enhancing the acoustic attenuation and vibration damping of a material by (1) embedding a plurality of small particles of either a high characteristic acoustic impedance or a low characteristic acoustic impedance or combinations of high and low characteristic acoustic impedance materials to form a matrix material to act as a acoustic attenuator or vibration damper; and (2) combing this matrix material with a second layer of a decoupling material that serves to effectively isolate the matrix material and reduce its tendency to vibrate sympathetically to the impinging acoustic energy. The mass of the resultant material may be very low while retaining excellent acoustic attenuation, vibration damping, and structural characteristics.

Abstract: The present invention relates to a therapeutic composition for treating a wide variety of medical conditions, in particular a topical therapeutic composition for treatment of acne and other skin lesions/conditions. The invention also relates to methods of treatment utilizing this composition. The composition comprises, in a concentrate form, Tarrow Root Extract, Kafferlime Leaf Extract, iodine, and optionally Vitamin E. The composition can be further diluted with hydrogen peroxide to prepare a ready-to-use-solution.
