Abstract: A live streaming system communicatively connected to a first camera, where the first camera captures an original image. The live streaming system includes a controller and an electronic device. The controller can send a prompt signal via the image captured by the first camera. The electronic device communicates with the controller and the first camera, and includes a processor and a network interface device. The processor recognizes the prompt signal in the captured image, and in response thereto, processes the original image to generate a synthesized image; it further analyzes the prompt signal to determine the location of the synthesized image. The network interface device is electrically connected to the processor and live streams the synthesized image.

Abstract: The present disclosure relates to a power supply device including a voltage conversion circuit, a switching circuit and a control circuit. The voltage conversion circuit is configured to generate a charging signal according to the power supply signal. The switching circuit is electrically connected to the voltage conversion circuit, and is configured to selectively conduct the voltage conversion circuit to a first device or a second device. The control circuit is configured to the switching circuit. When the voltage conversion circuit charges the first device and the charging signal corresponds to a first switching condition, the control circuit controls the switching circuit to disconnect to the voltage conversion circuit and the first device, then controls the switching circuit to connect to the voltage conversion circuit and the second device to charge the second device.

Abstract: The present invention provides an apparatus for expanding a serial communication port. The apparatus includes a first serial port, a second serial port and a processing and control module. The first serial port is used to transmit a first signal, and the second serial port is used to transmit a second signal. The processing and control module is coupled between the first serial port and the second serial port. The processing and control module includes a first serial bus host controller, a second serial bus host controller, a data forwarding unit and an expansion unit. The apparatus is connected between an electronic device and multiple peripheral devices, so that via the expansion unit, each peripheral device generates its own communication port on the electronic device.

Abstract: A Thunderbolt sharing console includes a high speed switch electrically coupled to at least one Thunderbolt host, a MCU coupled to the high speed switch, and a Thunderbolt interface chip coupled to the high speed switch, wherein the MCU can be used to control the high speed switch for determining which one of the at least one Thunderbolt host is coupled to the Thunderbolt interface chip.

Abstract: A switch device that allows a user to use the same non-Bluetooth user console (e.g., keyboard, mouse) to control both non-Bluetooth computers and Bluetooth master machines such as tablet computers, smart phones, etc. The switch device includes a console port for connecting to the console and one or more computer ports for connecting to one or more computers, as well as a Bluetooth module for communicating with Bluetooth master machines. A controller processes input device data received via the console port, and either sends the data to a selected Bluetooth master machine or a selected computer, or perform other functions such as switching, Bluetooth device pairing and disconnecting based on the input device data. The controller stores link information of the Bluetooth master machines already paired with the computer switch for quickly switching to a Bluetooth master machine. The switch device can be with or without video switching.
