Patent number: 8671235Abstract: 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.Type: GrantFiled: July 28, 2011Date of Patent: March 11, 2014Assignee: Aten International Co., Ltd.Inventors: Shu-Ching Tung, Ping-Wen Tsai, Hsiang-Jui Yu, Chao-Hsuan Hsueh

Patent number: 8521926Abstract: A desktop sharing and remote control system where the server (the computer being controlled) and the client (the computer controlling the server) are connected by a connecting device using the USB protocol. The connecting device includes a control unit (MCU) and two USB controllers. The MCU transfers data between the two USB controllers. The server-side USB controller emulates a USB CD-ROM/keyboard/mouse composite device; the client-side USB controller emulates a USB CD-ROM. The server continuously writes video data (desktop image) to the server-side emulated CD-ROM and the client continuously reads the data from the client-side emulated CD-ROM and applies it to its monitor. Keyboard and mouse data is transferred in the opposite direction via the client-side emulated CD-ROM and server-side emulated keyboard and mouse devices. The connecting device stores applications programs to be automatically executed by the server and client using auto-run functions of the emulated CD-ROMs to accomplish plug-and-play.Type: GrantFiled: September 25, 2008Date of Patent: August 27, 2013Assignee: Aten International Co., Ltd.Inventors: Chao-Hsuan Hsueh, Hsin-Mao Shen
