Abstract: An actuator control apparatus including a by-wire control circuit, a monitor circuit, a drive determination section, and a prohibition section is provided. The by-wire control circuit electrically controls an actuator acting as a drive source of an on-board apparatus. The monitor circuit monitors whether or not the by-wire control circuit is normally operating. The monitor circuit is provided separately from the by-wire control circuit. The drive determination section determines prohibition and permission of driving the actuator. The prohibition section prohibits the actuator from being driven when the permission of driving the actuator is not determined by the drive determination section. The prohibition section also prohibits the actuator from being driven when the monitor circuit determines that the by-wire control circuit is not normally operating.

Abstract: A voice conference system has a first voice-conference device having a speaker directed toward a first conferee and a second speaker directed toward a second conferee in one talk session room, and a second voice-conference device having a speaker directed to a third conferee and a fourth speaker directed toward a fourth conferee in another talk session room. When the first conferee talks, voice collecting beam signals picked up by microphones of the one voice conference device in excess of a predetermined threshold value are selected. The one voice conference device acquires voice collecting direction information, and then transmits voice communication data containing the voice collecting beam signal and the acquired voice collecting direction information to the another voice conference device, which acquires the voice collecting direction information from the received voice communication data, and emits the voice of the first conferee from the first speaker.

Abstract: A plurality of speakers are linked in the present invention. The linked position of each speaker can be detected. Audio signal is input to any one of the master speakers. The master speaker synchronizes the other linked speakers, and supplies audio signals to other speakers. It also controls the delay quantity of the speaker unit of each speaker. For a single speaker, the apparent width of this array speaker system becomes twice the width, and the speaker unit spacing becomes one third the spacing. Consequently, the frequency band at which direction is controllable becomes enhanced. Additionally, a plurality of microphone devices are linked at the top, bottom, left and right sides in the present invention. The linked position of each microphone device can be detected. Audio data is output from each microphone device to the master microphone device.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: An array loudspeaker is constructed by stacking loudspeaker rows in a plurality of stages, each of the loudspeaker rows being formed by arranging loudspeaker elements in the form of a horizontal line. The loudspeaker rows are arranged in a zigzag form by, for example, offsetting the positions of the loudspeakers in the left and right direction for each stage. As for a high range signal, a two-stage portion of halves of the loudspeaker rows is used to narrow the pitch of the loudspeaker elements so as to prevent the grating lobe. As for a low range signal, the entire single-stage loudspeaker row is used to alleviate the deviation with respect to the directivity characteristics of the high range.
