Abstract: Disclosed is a system interfacing architecture, and includes a system server, a communication network, and a plurality of client devices. The system server includes a virtual machine and performs a server operation, and each of the client devices executes a respective client operation. The client devices running an android operation system are connected to the system server running an X86 windows operation system by TCP/IP through the communication network. The server operation includes steps of logging in, entering regional disk, invoking the virtual machine, linking to the network, and executing a server window application. The client operation includes steps of executing a specific android application package, keying in an account number, displaying a window environment, and performing a client window application. In particular, the client device employs the client window application to communicate with the system server running the client window application for mutual operation.

Abstract: A mobile computer-based host includes a main body, at least one multifunctional module, and at least one lid. Each multifunctional module has the same size and shape. The main body includes a case and a host module, and the case encloses the host module and includes at least one module slot, each having the same size and shape for accommodating the multifunctional module. The lid covers the corresponding module slot to isolate and protect the multifunctional module. The module slots of the present invention are allowed to install the various multifunctional modules to provide different and specific functions without changing the original design of the size and shape. Thus, the application field of the mobile computer-based host is widely expanded to meet various demands in the future, and the lifetime is greatly prolonged without wasting any precious resource, thereby achieving the goal of environmental protection.

Abstract: Disclosed is a transparent electronic speaker device, including a transparent speaker, a touch control panel and a display panel which are sequentially stacked. The touch control panel provides a touch control function, and the display panel possesses a display function. The transparent speaker includes an upper conductive plate, a lower conductive plate and a transparent piezoelectric film sandwiched between the upper and lower conductive plates. The display panel generates and transfers a voltage driving signal through an electrical connection to the upper and lower conductive plates for actuating the transparent piezoelectric film to perform piezoelectric action, thereby generating vibration and sound. Therefore, the present invention not only integrates the functions of speaker, touch control and display, but also improves sound quality by use of the transparent piezoelectric film covering the whole electronic device without deteriorating display quality.

Abstract: The present invention relates to a method for preventing system invalidation including the microcontroller transferring the specific packet to the primary electronic device which operates according to the operation commands sent from the upstream device to provide the specific service, the primary electronic device returning the return packet, the microcontroller receiving the return packet, the microcontroller determining if the return packet is returned within a preset rang, if yes, repeating the above steps, if not, activating the spare electronic device to take over the primary electronic device to provide the specific service, and shutting down power supply of the primary electronic device. Therefore, the present invention ensures the spare electronic device smoothly takes over the task of the primary electronic device which accidentally fails, thereby preventing the whole system from being invalidated and improving the stability and reliability of the system operation.
