This invention relates to Bluetooth earphone. Existing Bluetooth earphones have some problems: users must wear the earphone to use it, so that the user will feel uncomfortable if the user uses the earphone for a long time. In order to solve these problems, this invention has added a speaker with larger power (i.e. 3W) and configured corresponding speaking amplifying circuit and switching circuit based on the existing Bluetooth earphones. With these new features, the user can adjust his/her Bluet...

Bluetooth range extending apparatus is disclosed for extending the range of Bluetooth communication between a master and an associated slave device. The apparatus (2) comprises a first communication module (3) for receiving incoming Bluetooth signals carrying data and extracting the carried data, and a second communication module (3) for re-encoding the extracted data and transmitting corresponding outgoing Bluetooth signals.

A Bluetooth terminal, relay, and system for determining a network configuration automatically and for transferring to an optimal waiting state. A Bluetooth terminal is provided with a profile functioning as a headset for communicating a terminal on the partner side via a voice gateway terminal, includes an input key for accepting an input operation including a transmitting operation, a receiving operation, and a call termination operation. A waiting state selecting member is provided for selecti...

A hub includes a bluetooth system module coupled to a hub module. The hub module is also coupled to an upstream port and a plurality of downstream ports provided on a housing of the hub respectively enabling the hub to connect to an electronic device via the upstream port and to connect to a plurality of peripherals via the downstream ports for performing a wireless signal communication therebetween, thereby reducing the number of cables connected between the electronic device and peripherals.

The present invention provides a method for automatically selecting, as a master, an optimum Bluetooth device for the master which can be stably connected to more devices in a Bluetooth network. According to the present invention, each of Bluetooth apparatuses capable of being masters acquires the device address of the connectable Bluetooth apparatus in response to an inquiry at 101, then, the each Bluetooth apparatus capable of being the masters acquires evaluation information such as the numbe...

A method, apparatus, and computer program product provide applications and application developers with generic access from user mode to the L2CAP layer of Bluetooth by exposing the L2CAP layer to user mode via a socket interface. In particular, a kernel mode primary component and user mode helper component cooperate to expose a Winsock interface to user mode components, and to manage various Bluetooth-specific functions and operations, allowing a user mode user application to access Bluetooth fu...

A system and method of Bluetooth compliant architecture and communication uses a miniport driver structure to efficiently implement the Bluetooth protocol layers, while allowing simple communication with underlying hardware.

The present invention relates to a Bluetooth-IP access system, and provides the Bluetooth-IP access system capable of performing broadband, large capacity and fast access by providing a Bluetooth-IP accessing device and a Bluetooth terminal with a module supporting broadband, large capacity, and fast search mounted therein.
