Abstract: An image sensor device includes a substrate, a photo sensitive element, a first dielectric structure and a convex dielectric lens. The substrate has a first side and a second side opposite to the first side. The photo sensitive element is formed on the first side of the substrate for receiving incident light transmitted through the substrate. The first dielectric structure is formed on the second side of the substrate. At least one portion of the convex dielectric lens is located in the first dielectric structure. The convex dielectric lens has a convex side oriented toward the incident light and a planer side oriented toward the photo sensitive element.

Abstract: The present disclosure provides an image sensor device and a method for manufacturing the image sensor device. An exemplary image sensor device includes a substrate having a front surface and a back surface, a plurality of sensor elements disposed at the front surface of the substrate. Each of the plurality of sensor elements is operable to sense radiation projected towards the back surface of the substrate. The image sensor also includes a high-k dielectric grid disposed over the back surface of the substrate. The high-k dielectric grid has a high-k dielectric trench and sidewalls. The image sensor also includes a color filter and a microlens disposed over the high-k dielectric grid.

Abstract: A lighting apparatus for a projector comprises a control module, a lamp driver and a transient voltage suppression circuit, in which the control module is used for generating a lighting signal, the lamp driver is used for receiving the lighting signal and controlling a lamp according to the lighting signal, and the transient voltage suppression circuit is disposed between the control module and the lamp driver, used for transmitting said lighting signal to the lamp driver and attenuating a high transient voltage generated at the instant the lamp driver lights up the lamp. The present invention is used to lower the high transient voltage through the transient voltage suppression circuit. Whereby, the control module is protected and the stability of the projector is further enhanced.

Abstract: An auto-turning on/off module is used for controlling projection apparatus to process an auto-turning on/off action according to an auto-turning on/off procedure and comprises a first central processing unit, a second central processing unit and a memory. The first and the second central processing unit are disposed in the projection apparatus and electrically coupled with each other. Furthermore, the memory is electrically coupled with the first central processing unit and/or the second central processing unit to use for recording an execution state of the auto-turning on/off immediately. Besides, an auto-turning on/off method is to turn on the projection apparatus first and then to input a turning on/off parameter into the projection apparatus to build the auto-turning on/of procedure. Thereafter, it is to execute the auto-turning on/off procedure and record the execution state of the auto-turning on/off immediately through the memory.

Abstract: A method and apparatus for monitoring signals of a projector includes a power supply, a signal-processing unit, a control unit, a starter and a lamp. The power supply provides the power, and then the signal-processing unit transmits the starting signal to the starter. The control unit monitors and determines if the signal is normal, and then controls the power supply and the signal-processing unit according to the signal. Therefore, the present invention can prevent the lamp from bursting, increase the safety of the users, and raises the stability of the projector.
