An electronic device having a user interface for accessing phone features. The user interface accounts for whether the electronic device is connected to a companion cellular phone. The user interface accounts for a headset is available for use to carry on a call. The user interface permits transition between using one or more of cellular phone, headset, and/or the electronic device to be used for carrying on incoming or outgoing calls.

A nurse call system that enables a call for a nurse from anywhere in a hospital ward while a patient carries a mobile phone is provided. The nurse call system includes a plurality of patient mobile phones 10 are carried by hospitalized patients and connected to a controller 8 via a base station 12 as with nurse mobile phones 9, and each patient mobile phone 10 has a hospital room ID and a nurse call slave device ID registered therein for recognizing a bed location of the patient carrying the patient mobile phone 10, thus enabling a nurse call operation for transmitting a call signal with the hospital room ID and the slave device ID added thereto, to the nurse call master device 7 and at least one of the nurse mobile phones 9, through a predetermined operation.

A smart watch according to the present invention comprises: a reception unit to which an analog speech signal is inputted; a first amplification unit for amplifying the analog speech signal; an A/D converter for converting the amplified analog speech signal into a digital speech signal; a control unit for receiving and outputting the digital speech signal outputted from the A/D converter and outputting a digital speech signal received and inputted through an antenna; an RF transceiver for controlling signals such that the signal received through the antenna is inputted to the control unit, and the signal outputted from the control unit is transmitted through the antenna; a D/A converter for converting the digital speech signal into an analog speech signal; a second amplification unit for amplifying the analog speech signal; and a speech output unit for outputting the analog speech signal outputted from the second amplification unit.

Provided is a setting method of a Wi-Fi doorbell (2), in which a Wi-Fi doorbell (2) comprising a camera capable of reading a two-dimensional code and a mobile communication terminal (4) comprising a display unit (6) capable of displaying the two-dimensional code are used. The setting method comprises steps of causing the display unit (6) to display a two-dimensional code in which password information for enabling the Wi-Fi doorbell (2) to connect to a network (5) via a Wi-Fi router (20) is embedded reading the two-dimensional code by the camera (9) of the Wi-Fi doorbell (2); and setting the Wi-Fi doorbell (2) to a state where the Wi-Fi doorbell (2) can perform communication with a remotely disposed server (3) via the Wi-Fi router (20), based on the read two-dimensional code.

A nurse call system of the present disclosure includes: a nurse call slave unit; a nurse call master unit; a mobile terminal; an access point for relaying communications between the mobile terminal and the nurse call master unit; a private branch exchange configured to control communications between the nurse call slave unit and the mobile terminal; and a chat server configured to generate a chat room to be delivered to the mobile terminal in response to a call originated from the nurse call slave unit, in which the chat server generates a chat room with in-charge healthcare workers in charge of a subject patient who originated a call using the nurse call slave unit and a nearby healthcare worker assumed to be at a location closer to the subject patient than the in-charge healthcare workers are as users, and provides the chat room to each mobile terminal.

Systems and methods are disclosed for audio group identification for conferencing. For example, methods may include joining a conference call using a network interface; accessing an audio signal that has been captured using a microphone; detecting a control signal in the audio signal; and, responsive to detection of the control signal, invoking modification of an audio path of the conference call.

An intercommunication system includes one or more modular units utilizing a standards-based audio-over-IP configuration. The modularity of the system provides improved scalability. For instance, a number of audio channels is not limited by physical constraints (e.g. number and type of ports) of a central switch. Accordingly, the addition of audio channels may not require swapping one central switch for a larger switch. Moreover, security applications may be layered onto the standards-based audio-over-IP configuration to implement security requirements often found with intercommunications systems.
