Latest Patents

Tohru Abe holds a patent for an audio teleconferencing apparatus. This invention allows for two-way communications between more than two parties without the need for complete switching. It effectively prevents an increase in loss within the communication channel of a particular speaker. The apparatus includes multiple line interface circuits, each equipped with a voice activity detector. This detector identifies voice activity in a received speech signal. Additionally, it features a received-speech variable loss that inserts a loss into the speech receiving path when the received speech signal is voice non-active. Furthermore, a sending-speech variable loss is included to manage the speech signal transmission path when the speech to be sent is voice-active. This innovative design ensures that a certain loss is inserted in any four-wire multiplex loop within the line interface circuit.
