Abstract: Device called ear unit for stable fittings in an ear, characterised in that said ear unit (10) is shaped as a decremental curve and that the distance between the ends (5, 8) of the decremental curve is approximately equal to the distance between a first cavity from the under the tragus (4) of the ear and second cavity covered by the lower node (15) of the antihelix of the ear, the upper part of the curve projecting in underneath a flap (2) covering the lower part of the second cavity, and said ear piece having a curvature providing an improved attachment in that said curvature follows the bottom of the ear mussel (22). The ear unit (10) optionally comprises a part (T) extending downwards, the transition between said part (T) and the ear piece is formed in such a way that it aligns along the intertragic notch (14). The ear unit is optionally arranged with at least one unit from the group comprising ear phone and microphone.

Abstract: Bidirectional communication is performed by an application employing particular communication protocols without depending on any specific network environment enabled by an OS and the like. There is provided a communication module installed in a client apparatus for connecting an application software program to a virtual network via a server on the Internet. This module interposes between the application software program in a computer and a group of local communication protocol stacks of an operating system installed in the computer; retains a virtual network address for the application software program; performs the tunneling processing on packets from the application software program to the virtual network to thereby pass the processed packets to the server through the local communication protocol stacks; and is provided with Layer 2, 3 and 4 protocol stacks that are independent of a group of local communication protocol stacks.

Abstract: A simple means is used to realize a virtual network communication via an home network and Internet. A relay device 4 comprises bridge module 12 provided between a network protocol stack 13 and each of network devices 10, 11 for bridging for packets which are not addressed to the relay device or VLAN, or not broadcast request packets; a server address storage section 17 for storing the global address of a server; a tunneling session establishing section 20 for establishing a tunneling connection with the server based on the global address; a capsulating processing section 21 for capsulating a originating address and sending it to the server via the tunneling connection; and a virtual IP address/private IP address conversion section 22 for decapsulating a packet addressed to the relay device, converting a destination virtual network address included in this packet to a private IP address on the LAN of a client apparatus, and sending it onto the LAN via the bridge module.

Abstract: A system for Internet connections, which connects a user terminal to a network. The system generally comprises a section for relaying a network connection from a user through an access point, a monitoring section for monitoring the network connection from the user through the access point, and a network connection fee calculation section for calculating a network connection fee for the user based on a monitoring result of the monitoring unit. The connection fee calculation section comprises a line connection fee calculation section for calculating a line connection fee for a line connection made by the user to the access point based on user signal source information, which is provided from a telephone company, and a charge amount calculation section for calculating a charge amount for the user based on the line connection fee, calculated by the line connection fee calculation section.

Abstract: The objective of the present invention is to provide an Internet connection system capable of bi-directional communications between the home network and the Internet by relatively simple means, enabling manufacturers of client-end home network appliances to create added values for users. In order to attain the above objective, there is provided a method for connecting a client device and a server. The method is implemented on an Internet connection system, which has the client device, a relay device, and the server, the server being connected to the Internet and also to the client device through the relay device and the Internet. The method includes the steps of: (a) notifying the relay device of an IP address of the server; (b) enabling the relay device to establish a TCP/IP session by means of a tunneling connection between the relay device and the server by use of the IP address; and (c) enabling the relay device to route communications via the TCP/IP session from the server to the client device.
