Abstract: A stereoscopic display system and a control method of the stereoscopic display system are provided. A rotation device is controlled to rotate at 2n times an image input frequency, so that the rotation device respectively completes n rotations during a period in which stereoscopic glasses receive a left-eye image and a period in which the stereoscopic glasses receive a right-eye image.

Abstract: A projection apparatus, a power management apparatus, and a method for power management thereof are provided. The projection apparatus has a first power socket corresponding to a first power specification and a second power socket corresponding to a second power specification. The second power specification is different from the first power specification. A voltage detection unit is adapted to detect an input voltage received by a powered power socket, wherein the powered power socket is the first power socket or the second power socket. A control unit decides whether the input voltage detected by the voltage detection unit is matched up with the power specification of the corresponding powered power socket to determine an operation mode of the projection apparatus and to determine whether the projection apparatus provides an alarm message to ensure safety of use.

Abstract: Metamaterial devices with environmentally responsive materials are disclosed. In some embodiments, a metamaterial perfect absorber includes a first patterned metallic layer, a second metallic layer electrically isolated from the first patterned metallic layer by a gap, and an environmentally responsive dielectric material positioned in the gap between the first patterned metallic layer and the metallic second layer.

Abstract: A reset circuit and a reset method for a high definition multimedia interface (HDMI) are provided. The reset circuit includes a first resistor, a second resistor, and a regulation unit. When a host system changes resolution of multimedia data, the regulation unit regulates a hot-plug detect signal to generate a logic low level pulse signal, so as to reset the data connection between the host system and a display apparatus. Thus, the multimedia data are displayed normally without resetting a connector.

Abstract: This invention relates to an eye-tracking driving system, especially to an eye-tracking system controlled by the user's eye. It not only utilizes the unique eye-controlled method, but also avoids contacting with the user's eyes or skin. It is suitable for the disabled persons or the elderly so that they can drive a powered vehicle easily. The system mainly includes a display device, an eye-tracking device, a calculating device, a controller and a powered vehicle. This system can effectively capture the image around the user's eye and then precisely determine the pupil center. Based on the position of the pupil center, the power vehicle can be controlled.
