Methods, systems, and apparatus for call prompting when a call initiated by a terminal is unconnected during a call between two other terminals. In one example method, a first interface, indicating that the first terminal is in a call with a second terminal, is displayed on the first terminal. If a third terminal initiates a call to the first terminal, a second interface, indicating the call initiated by the third terminal, is displayed on the first terminal, and a sound, which includes a call voice and a prompt tone of the initiated call, is output. If the third terminal's initiated call is rejected, the call voice is output on the first terminal, and the prompt tone stops being output. If the third terminal stops initiating the call, the first interface is displayed on the first terminal, and the call voice between the first terminal and the terminal continues being output.

A sealing unit used to block liquid comprises a sealing block, a receiving hole, a wire-through hole, and a sealing piece. The receiving hole penetrates the sealing block. The sealing piece is received in the receiving hole. A surface of the sealing block is in contact with the receiving hole. A material of the sealing piece is elastic material. The sealing piece is penetrated by the wire-through hole and forms an open penetrating structure. The present disclosure also provides a wireless intercom device using the sealing unit.

The invention relates to, among others, a network device (10, 11, 12) for an intercom network (13) for permitting an audio communication, in particular a duplex audio communication with other users (14a, 14b, 14c, 14d, 14e, 14f) of the intercom network, comprising a housing (33) and a communication module (20a, 20b) arranged therein or thereon, with which a radio link can be established for the transmission of audio signals to another user, wherein the radio link is subject to the DECT protocol. The speciality, among others, consists in that the network device (10, 11, 12) comprises a means (21) for preventing or reducing multipath interferences.

In general, the invention relates to a method of interactive and live computerized matching in which a first user has a personal data device including a wireless communication system. A network is configured to include a server programmed with a personal characteristic database and a database searching algorithm, and a wireless communication system that is capable of communicating with the user's personal data device. The first user is allowed to log on through the wireless communication system to the network using his or her personal data device, and communicates to and stores in the database personal data defining his or her characteristics and those for his or her ideal match. Either the secure network automatically identifies the first users precise geographic location, or the user himself otherwise indicates and stores in the database of the network an identifying address that indicates his current specific geographic location. The user then instructs the database searching algorithm to search for and identify other users on to the network near the same geographic location to facilitate a match.

The invention relates to, among others, an intercom network (10), comprising a plurality of speech stations (11a, 11b, 11c) and at least one switching center (13, 16), wherein from each speech station connected to the switching center a connecting line (12a, 12b, 12c) extend to the switching center, wherein the connecting line provides a direct connection, respectively, between the switching center and the connected speech station, and wherein the speech stations of the intercom network, due to an audio data communication via the switching center, can enter into audio communication in real time. The particular feature consists, among others, in that at least one speech station (11a) comprises a terminal (53, 54) for a second connecting line (50, 50a, 50b, 50c), via which the speech station is connected with the same switching center (13) or with another switching center (16).

Phone systems, phone devices (including hardware, software and firmware), and methods of operating a phone. Described herein are dissociated phone systems including one or a plurality of local client phones with basic call handling capability that communicate though a remote phone server but are locally controlled by a controller gateway that manages the local network including the local client phones.

In general, the invention relates to a system and method of operating a shopping system to facilitate payment using a mobile device. A network is configured to include a server programmed with a personal characteristic database, a database searching algorithm, and to be coupled to a wireless communication system that is capable of communicating with the user's personal data device. The user logs on through the wireless communication system to the secure network using her personal data device, and communicates to and stores in the database personal data defining her characteristics. Either the secure network automatically identifies the first users precise geographic location, or the user himself otherwise indicates and stores in the database of the network an identifying address that indicates his current specific geographic location. Personal data defining the user's characteristics are then sent to a business location at the user's location to facilitate a payment transaction.

An auxiliary radio communications system includes a dispatch radio console (DRC), a plurality of antennas, and a radio amplification unit (RAU). The RAU includes first and second repeaters that are in communication with an RAU interconnect board. The first and second RF repeaters receive first and second communication signals from the RAU interconnect board, respectively, and retransmit them to the antennas and to the DRC. The antennas rebroadcast the first and second communication signals over first and second communication channels, respectively. The DRC can include first and second dispatch control modules (DCMs) that receive the first and second communication signals, respectively. The first and second communication signals can originate from the first and second DCMs, respectively, from a first handheld radio tuned to the first communication channel, and/or from a second handheld radio tuned to the second communication channel.

The present disclosure relates to a call prompt method. In one example method, a first interface, indicating that the first terminal is in a call with a second terminal, is displayed on a first terminal. If a third terminal initiates a call to the first terminal at this moment, a second interface, indicating the call initiated by the third terminal, is displayed on the first terminal, and a sound is output. The sound includes a call voice and a prompt tone of the initiated call. If the call initiated by the third terminal to the first terminal is rejected, the call voice is output on the first terminal, and the prompt tone stops to be output. Or if the third terminal stops initiating the call, the first interface is displayed on the first terminal, and the call voice between the first terminal and the terminal continues to be output.
