Abstract: Embodiments of this application disclose method and apparatus for positioning a target audio signal by an audio interaction device, and an audio interaction device The method includes: obtaining audio signals in a plurality of directions in a space, and performing echo cancellation on the audio signal, the audio signal including a target-audio direct signal; obtaining weights of a plurality of time-frequency points in the audio signals, a weight of each time-frequency point indicating, at the time-frequency point, a relative proportion of the target-audio direct signal in the audio signals; weighting time-frequency components of the audio signal at the plurality of time-frequency points separately for each of the plurality of directions by using the weights of the plurality of time-frequency points, to obtain a weighted audio signal energy distribution; and obtaining a sound source azimuth corresponding to the target-audio direct signal in the audio signals accordingly.

Abstract: Disclosed are a device, system, methods and computer-readable medium products that provide an updated insulin-to-carbohydrate ratio and an updated total daily insulin. The described processes may be used for periodic updating of the insulin-to-carbohydrate ratio and the total daily insulin. The insulin-to-carbohydrate ratio and/or the total may be used in the calculation of new doses of insulin that a drug delivery device may be commanded to deliver to a user.

Abstract: A method for producing a Spar Cap, trailing edge or other reinforced laminate structural part of wind turbine blade, the Spar Cap, trailing edge or other reinforced laminate structural part of wind turbine blade produced by the method and its use are provided. The method for producing a Spar Cap, trailing edge or other reinforced laminate structural part of wind turbine blade improves production efficiency and saves costs.

Abstract: A method for preparing a polyurethane composite by a vacuum infusion process, a polyurethane composite prepared by said method and use thereof. The method for preparing a polyurethane composite by a vacuum infusion process of the present invention can reduce raw materials and production costs.

Abstract: The invention relates to a method for preparing a polyurethane composite by vacuum infusion process, the composite prepared by the method and use thereof. The method according to the present invention preferably comprises the use of a polyester peel ply having a specific gram weight, a reinforced material and/or a porous medium, and the like. The polyurethane composite produced by the method according to the present invention has both good physical properties and a satisfactory outer surface without the need to separately treat the outer surface.
