摘要： Microphones arranged in an array shape along a longitudinal direction are respectively formed in both the longitudinal side surfaces of a housing 2 with substantially an elongated rectangular parallelepiped shape, and speakers arranged in an array shape along the longitudinal direction are formed in a lower surface. The speaker array forms sound emission beams based on sound emission directivity set according to a conference environment. On the other hand, when the microphone array forms sound collection beams by sound collection signals collected, a talker direction is detected from these beams and an output sound signal corresponding to this direction is formed and also is reflected on setting of the sound emission directivity. Also, when there are plural input sound signals, the sound emission directivity is set according to a use situation of the plural input sound signals.

摘要： A control unit gives acoustic environment instruction data to a picked up sound directionality control unit and an adaptive filter. According to this, the picked up sound directionality control unit generates a picked up sound signal constituted by a predetermined picked up sound directionality. The adaptive filter detects the picked up sound directionality from the acoustic environment instruction data, and reads out the filter parameter corresponding to this picked up sound directionality, from a memory. The adaptive filter sets a delay coefficient and a filter coefficient of an FIR filter, and generates a pseudo echo signal by an impulse response with respect to the received sound signal. Based on an error signal obtained by subtracting the pseudo echo signal from the picked up sound signal by an adder, the adaptive filter sets a more optimum filter parameter, and generates the next pseudo echo signal.
摘要翻译：控制单元向拾取的声音方向性控制单元和自适应滤波器提供声环境指令数据。据此，所拾取的声音方向性控制单元产生由预定拾取声音方向性构成的拾取声音信号。自适应滤波器从声环境指令数据检测拾取声方向性，并从存储器读出对应于该拾取声方向性的滤波器参数。自适应滤波器设置FIR滤波器的延迟系数和滤波器系数，并且通过相对于接收到的声音信号的脉冲响应来产生伪回波信号。基于通过加法器从拾取声音信号中减去伪回波信号而获得的误差信号，自适应滤波器设置更优化的滤波器参数，并生成下一个伪回波信号。

摘要： A position detecting system capable of detecting the position of a user as a listener in a simple manner. The position detecting system comprises a speaker system comprising a plurality of spatially-arranged speakers including at least a first speaker and a second speaker, a user terminal apparatus transmits a wireless signal to the speaker apparatus, and a position detecting apparatus which is provided in the side of the speaker apparatus. The position detecting apparatus computes the position of the user terminal apparatus based on a first time elapsed since the first speaker outputs a first measurement sound signal and until a receiving command transmitted by the user terminal apparatus in response to receiving the first measurement sound signal is received, and a second time elapsed since the second speaker outputs a second measurement sound signal and until a receiving command transmitted by the user terminal apparatus in response to receiving the second measurement sound signal is received.

摘要： A photoconductive phthalocyanine composition is disclosed, comprising (A) a photoconductive phthalocyanine composition comprising 100 parts by weight of an unsubstituted phthalocyanine derivative and from 0.001 to 5 parts by weight of a nitro- or halogen-substituted phthalocyanine derivative and (B) from 0.01 to 10 parts by weight, per 100 parts by weight of the photoconductive phthalocyanine composition (A), of a phthalocyanine derivative having at least 4 electron attracting groups. A photosensitive layer formed of the photoconductive phthalocyanine composition produces digital signals whether input light is digital or not. It is useful as not only a photoreceptor for digital recording system of electrophotography but a photoreceptor for analogue light input in conventional PPC to provide a high quality image with sharp edges.
