摘要： A teleconferencing apparatus includes the functions of a transmitting unit and a receiving unit and the transmitting unit transmits a sound signal formed from sound pick-up signals of a microphone array made up of microphones Mi (i=1 to N) and position information. The position information is provided by forming a plurality of sound pick-up beams directed in a specific direction and selecting the sound pick-up beam with the largest volume. In the receiving unit, a parameter calculation section sets a virtual sound source based on data of a reception signal and sets a delay parameter. A virtual sound source generation signal processing section forms a sound emission beam based on the parameters and outputs the beam to a loudspeaker SPi.

摘要： A light-emission responder can respond to input of sound, realizes versatility of response, and can be applied to various use forms. A microphone (110) converts a sound wave into an electric signal. An amplifying section (111) amplifies the electric signal and outputs it to an AGC section (112). The AGC section (112) adjusts the amplitude of the electric signal output from the amplifying section (111). A filter section (113) outputs an electric signal in a frequency band f1 out of the amplitude-adjusted electric signal to a comparing section (114). The comparing section (114) compares the input electric signal with a reference signal. If the voltage of the electric signal passing through the filter section (113) is higher than the reference voltage, the comparing section (114) outputs a signal “H”. When a signal “H” is output from the comparing section (114), a drive section (115) allows a light-emitting element (120) to emit light. A light-emission response output section (116) is connected to the drive section (115). When driven by the drive section (115), the light-emission response output section (116) outputs a radio wave of a predetermined frequency.

摘要： An optical disk recording apparatus operates on an optical disk having circular tracks which are provisionally written with an index signal used for securing a constant linear velocity of the optical disk from an innermost circular track to an outermost circular track, and records data along the circular tracks at different linear densities on different annular zones of the optical disk. In the apparatus, a disk drive section rotates the optical disk while synchronizing the index signal successively read from the rotated optical disk with a predetermined reference clock signal to thereby maintain the constant linear velocity of the circular tracks. A clock generating section multiplies or divides the reference clock signal by different rates to generate different writing clock signals in correspondence to the different annular zones of the optical disk. A data recording section operates in synchronization to the different writing clock signals for recording data along the circular tracks at the different linear densities on the different annular zones.

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。

A talk session device 1 includes a network processing portion for transmitting/receiving voice information to/from other equipments via IP, and a terminal for inputting/outputting a voice signal. The talk session device 1 is connected to a handset terminal of a telephone 3 via an adaptor 2 that converts the standards (mainly a level) of the voice signal. The talk session device 1 is connected to other talk session devices via IP, and is connected to other telephones by a telephone line via the telephone 3. Accordingly, a user serving as a destination of the IP and a user serving as a destination of the telephone line are connected mutually.

摘要： An optical disk recording apparatus is designed for forming pits on a recording surface of an optical disk of a given type at a given recording speed by applying a laser light in the form of a sequence of multiple pulses obtained by intermittently turning on and off the laser light according to a given multi-pulse pattern. In the apparatus, a write strategy circuit is set with a pattern table and controls the turning on and off of the laser light according to a multi-pulse pattern selected from the pattern table in correspondence to a length of the pit to be formed. A storage section stores a plurality of pattern tables of different kinds, each pattern table containing a plurality of multi-pulse patterns corresponding to a plurality of lengths of the pit. A control section selects one of the pattern tables based on either of the recording speed and the type of the optical disk, and reads out the selected pattern table from the storage section and sets the read pattern table in the write strategy circuit.

摘要： An optical recording method is designed for recording data on a recordable optical disk by use of a laser beam of a present recording apparatus under a desired recording condition. The method detects identification information which is reserved in the optical disk and which is indicative of a type of a previous recording apparatus. The detected identification information is compared with a plurality of identification information which are previously stored in correspondence to various types of recording apparatuses. As results of the comparison, the method determines whether the detected identification information matches with one of the stored identification information which does not correspond to the type of the present recording apparatus. Upon the determining of matching, the method retrieves a recording condition which is previously stored in association with the matching identification information. The recording of the data is performed on the optical disk by the present recording apparatus with use of the retrieved recording condition.
