Abstract: Systems and methods for audio signal processing are disclosed, where a discrete number of simple digital filters are generated for particular portions of an audio frequency range. Studies have shown that certain frequency ranges are particularly important for human ears' location-discriminating capability, while other ranges are generally ignored. Head-Related Transfer Functions (HRTFs) are examples response functions that characterize how ears perceive sound positioned at different locations. By selecting one or more “location-critical” portions of such response functions, one can construct simple filters that can be used to simulate hearing where location-discriminating capability is substantially maintained. Because the filters can be simple, they can be implemented in devices having limited computing power and resources to provide location-discrimination responses that form the basis for many desirable audio effects.

Abstract: A method controls a projection of a projector. The method predetermines hand gestures, and assigns an operation function of an input device to each of the predetermined hand gestures. When an electronic file is projected onto a screen, the projector receives an image of a speaker captured by an image-capturing device connected to the projector. The projector identifies whether a hand gesture of the speaker matches one of the predetermined hand gestures. If the hand gesture matches one of the hand gestures, the projector may execute a corresponding assigned operation function.

Abstract: A method for manufacturing a metal base laminate includes the steps of providing a metal board having a first through-hole; forming a stack-up structure on at least one side of the metal board, wherein a resin film layer, a prepreg layer, and a metal foil layer are disposed in sequence on a metal board-bordered side of the stack-up structure; and laminating the metal board and the stack-up structure together. The method is effective in enhancing mechanical strength, reducing voids which might otherwise be left in through-holes not fully filled in a conventional via filling process, and further enhancing the processing characteristics of the metal base laminate thus manufactured, by using a prepreg and a resin film concurrently as an insulating material. A metal base laminate manufactured by the method is further introduced.
