Abstract: A video conferencing system is provided. The video conferencing system includes a first video conferencing apparatus and a second video conferencing apparatus. A video/audio connection of a video conference between the first and second video conferencing apparatuses is established via an SIP channel. When the video/audio connection of the video conference has been established, a transparent layer is activated on the first and second conferencing apparatuses. When the first and second video conferencing apparatuses are switched to an external output projection mode, first and second touch events are input on the first and second video conferencing apparatus, and the first and second touch events are respectively transmitted to the second and first video conferencing apparatuses via the SIP channel. The first and second video conferencing apparatuses draw the second and first touch events on a first user interface and a second user interface.

Abstract: A video conferencing system is provided. The video conferencing system includes: a first communication device, configured to receive a video signal from a host, and convert the video signal into a first video stream; and a second communication device, configured to receive a second video stream of a scene captured by an image capturing unit, and receive the first video stream from the first communication device by using a wireless communication protocol, wherein the second communication device selects one of the first video stream and the second video stream according to a switching signal, and transmits the selected video stream to an electronic system, wherein when receiving the switching signal, the second communication device stops transmitting the selected video stream to the electronic system for a predetermined time period, and transmits header information of another video stream to the electronic system, thereby resetting decoding settings of the system.

Abstract: A wearable device applied to a human body is provided. The wearable device includes at least one sensing electrode, a conductive wire, a monitor device, and a shield element. The sensing electrode receives a physiological signal from the human body. The sensing electrode is coupled through the conductive wire to the monitor device. The monitor device is configured to process the physiological signal. The shield element includes metal fiber composition. The shield element covers the sensing electrode and the conductive wire so as to avoid electrostatic interference. The shield element is at least partially exposed to the human body.

Abstract: A Bluetooth communication system includes a remote device, having a first Bluetooth module, and a user device, having a second Bluetooth module, and communicating with the remote device through the first Bluetooth module and the second Bluetooth module in a link state. When the remote device and the user device are over a communication range, the remote device enters an access state. In the access state, the first Bluetooth module re-communicates with the second Bluetooth module by a link back mode in a first time interval and a standby mode in a second time interval and when the remote device comes back with the communication range, the communication with the user device is recovered.

Abstract: An automatic switch-dialing system and method are provided, that can be applied on a telephone set having both of the Public Switched Telephone Network (PSTN) and the Voice over Internet Protocol (VOIP) dialing capabilities. During dialing out a phone call, the prefix code and the phone number length of the dialed phone number are compared with those stored in a preset routing table, thus determining the dialing mode of the dialed phone call. As such eliminating the inconvenience of manual setting for the user, and realizing the optimized balance between saving telephone expenses and achieving better communication quality.

Abstract: A user self-expandable extension network system and its dialing and answering processes are applied to an extension network which consists of a plurality of extensions. An extension will send a detecting signal to locate the host phone and regard the host phone as a session initiation protocol (SIP) proxy server after receiving the reporting signal of the host phone. Therefore, the extension can be dialed or receive a phone call without being set up by the assistance of a professional technician.

Abstract: A phone device for the Public Switched Telecommunication Network (PSTN) and Voice over Internet Protocol (VoIP) network is provided. It is used to dial up through the PSTN and the VoIP network automatically or selectively, suitable for telecommunication networks of both inbound and outbound calls. A phone device includes a control circuit for coupling the analog phone module with the VoIP module, wherein the VoIP module is used for dial up through the PSTN, and a signal detection module is used to handle the operation timing between the VoIP network and the PSTN.
