A device for attracting and capturing or otherwise disabling insects includes a fan mechanism structured and arranged to provide an outflow of air out of the device to atmosphere, and to draw an inflow directed counter the outflow from atmosphere into the device, the outflow being substantially within the inflow outside of the device. A predetermined quantization noise threshold allowed during quantization of sampled audio data and quantization noise energy information of a quantized MDCT coefficient are received in all frequency bands of an audio frequency. The pinned surface layer is formed by employing the same mask level as the one employed for the formation of the photodiode region, and then implanting dopants at angles other than zero degrees.
