Abstract: A motor control apparatus includes: a converter circuit; an inverter circuit; a current detector; a regenerative resistor; a regenerative resistor controller; and a control device. The converter circuit converts alternating current from an alternating current power supply to direct current, converts regenerative direct current from the inverter circuit to regenerative alternating current, and further supplies the regenerative alternating current to the alternating power supply. The inverter circuit converts the direct current to alternating current for driving a motor, and converts regenerative alternating current from the motor to the regenerative direct current. The regenerative direct current from the inverter circuit passes through the resistor. The regenerative direct current passes thorough the resistor upon the current detector detecting the regenerative current exceeding a predetermined value.

Abstract: An impact of a delay time on a conversation is reduced. A voice packet is transmitted to a distribution server. A user is notified of being in a wait time from when transmission of the voice packet stops until when voice packet transmission becomes available next. The wait time is calculated on the basis of a first delay time that is a delay time between a local terminal and the distribution server and a second delay time that is the maximum delay time among delay times between a plurality of terminals including the local terminal and the distribution server. The user can easily know the speaking timing from the local terminal, and speech from the local terminal and speech from another terminal can be made not to mix.

Abstract: A communications server comprises a data receiver configured to receive status data indicating, for each communication terminal of a set of communication terminals, a current device status of that communication terminal; a terminal manager configured to assign each communication terminal of the set of communication terminals to one or more communication terminal groups in dependence upon the respective status data for that communication terminal; and a communications controller to control the transmission of communications data to each of the set of communication terminals in dependence upon the respective communication terminal group to which that communication terminal is assigned by the terminal manager.

Abstract: An utterance detection unit 232 detects an utterance period by an utterance detection unit on the basis of an input voice signal supplied from a microphone 31. A background sound generation unit 241 generates a background sound signal according to an utterance period detection result of the utterance detection unit. A voice synthesis unit 242 performs a synthesis process using the background sound signal generated by the background sound generation unit 241 to generate an output voice signal and outputs the same to a speaker 32. The control unit 26 sets a detection period of the utterance detection unit 232 on the basis of an operation signal in response to a user operation generated by an operation switch 33, and transmits the input voice signal of the utterance period from a transmission unit 211 of a communication unit 21, for example. A background sound indicated by the output voice signal makes it possible to easily determine whether or not it is in a voice transmission state.

Abstract: An apparatus and method for communicating between a first device and second device, where each device includes a motion sensor. Communication functions are triggered by comparing motion data derived from each device. For example, when the first device is worn on a user's wrist (e.g., a smartwatch) and the second device (e.g., a smartphone) is held in the user's hand corresponding to the user's wrist, then moving the hand and devices results in correlated motion data between the devices. This correlated motion indicates the devices correspond to the same user. Further, human-body communication between the devices provides additional indicia that the devices correspond to the same user. Thus, based on the above-identified correlated motion and human-body communication the same user can be inferred and predefined communication task between the devices can be performed, such as unlocking the devices, exchanging identification codes, or exchanging other information.
