Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: Circuits, methods, and apparatus that may reconstruct a data signal in the presence of ground drift and high-frequency signal coupling. An illustrative embodiment of the present invention may reconstruct a received data signal by taking an finite difference of the received data signal, detecting edges of the received data signal by detecting positive and negative peaks of the finite difference of the received signal, and reconstructing the received data signal using the detected edges. Taking a finite difference of the received data signal removes the DC component of the received data signal, as well as the ground drift that may cause the DC component of the received data signal to change over time. Additional filtering may be used to reduce high-frequency signal coupling and power supply inductive coupling.

Abstract: An explicit real-time fire disaster alarming device includes a fire disaster detector, human body detector, controller and outdoor light displaying portion. If the fire disaster detector detects any fire inside a space or room, it will send out a fire signal. The human body detector detects whether there is any human inside the space and send out a YES signal or a NO signal accordingly. When the controller receives the fire signal, the outdoor light displaying portion changes from a storing form to an extending form. When the controller receives the YES signal, the outdoor light displaying portion turns on a light for showing there is a human inside the space. When it receives the NO signal, the outdoor light displaying portion turns on another light for showing there is no human inside. Hence, fire fighters and rescuers are provided with a priority reference for life rescue.

Abstract: A virtual internet protocol (IP) gate, between a legitimate internet and a virtual internet, can reuse the internet address in a specific range of the legitimate internet addresses for resolving the insufficiency of IP addressing. The virtual IP gate at least comprises a connection module, a selection module and an address conversion module. The connection module establishes connection with the virtual internet by using at least a virtual internet address and establishes connection with the internet by using at least an internet address with the address not within the aforementioned range.
