Abstract: A sound amplification apparatus includes one or more microphones that convert collected sound into an audio signal and transmit the audio signal by radio and a sound receiving apparatus that receives the audio signal transmitted from the microphone and amplifies and outputs the sound based on the audio signal. The sound receiving apparatus is configured to perform sound output control in an emergency mode upon receiving an emergency signal transmitted in response to operation of an emergency switch of the microphone. With this configuration, it is possible to perform appropriate sound control in a dangerous situation such as intrusion of a suspicious person.

Abstract: A wireless communication apparatus which communicates with a first microphone is disclosed, which includes an audio processor which acquires audio data from the first microphone, a controller which detects an instruction for audio recording from the first microphone, an audio recorder which starts recording the audio data and stops the recording after a defined period of time since detection of the instruction for audio recording, a timer which starts measuring time for the defined period of time, and a memory controller which creates a recorded audio file, wherein the recorded audio file is linked to log information.

Abstract: The present invention provides an order receiving system includes an order receiving unit that receives an order for an item from a customer terminal; an information obtaining unit that obtains reference information for determining a condition for starting preparation for provision of the item; a start condition setting unit that sets the condition for starting preparation for provision of the item whose order has been received by the order receiving unit, based on a content of the order and the reference information; and a condition determining unit that determines, after receiving the order for the item by the order receiving unit, whether the condition determined by the start condition setting unit is satisfied. When the condition determining unit determines that the condition is satisfied, the transmitting unit of the wireless center module transmits a preparation start instruction signal to the wireless headset.

Abstract: An inter-communication system has a security functionality capable of reporting incidents such as abnormalities occurring in a security system. In an inter-communication system, if a communication sound control device receives an alarm from a security system via a main shop processing device, the communication sound control device notifies a predetermined order reception communication device, such as a manager communication device, of the reception of the alarm, and the main shop processing device reports to a preset destination over a communication network.

Abstract: The wireless communication system of the present invention has a first communication mode in which a center module preferentially allocates a slot to communication data of a calling sub station according to a priority of the calling sub station, and a second communication mode in which the center module allocates the slot to the communication data received from the calling sub station irrespective of the priority of the calling sub station. The center module determines which sub station can make a call to which sub station, each sub station transmits identification information to the center module, and the center module identifies the transmitting sub station based on the identification information, determines which sub station the identified sub station can make a call to, and allocates the slot to communication between the sub station determined to be capable of making a call and the transmitting sub station.

Abstract: An acoustic feedback suppression apparatus includes an amplitude measurement section for measuring the amplitude of a sound signal input from a microphone, an amplitude attenuation section for attenuating the amplitude of a sound signal output to a speaker, and an acoustic feedback determination section for determining whether or not acoustic feedback is occurring based on the sound signal input from the microphone. If it is determined that acoustic feedback is occurring, a sound-deadening control section enables sound-deadening control so that the amplitude of the sound signal output to the speaker is attenuated to a sound-deadening level. A sound-deadening release section releases the sound-deadening control if the amplitude of the sound signal input from the microphone is more than specified threshold amplitude and if it is determined that acoustic feedback is not occurring while the sound-deadening control is conducted.
