Abstract: An image sensor device has a first number of first pixels disposed in a substrate and a second number of second pixels disposed in the substrate. The first number is substantially equal to the second number. A light-blocking structure disposed over the first pixels and the second pixels. The light-blocking structure defines a plurality of first openings and second openings through which light can pass. The first openings are disposed over the first pixels. The second openings are disposed over the second pixels. The second openings are smaller than the first openings. A microcontroller is configured to turn on different ones of the second pixels at different points in time.

Abstract: A method of forming low-k material is provided. The method includes providing a plurality of core-shell particles. The core of the core-shell particles has a first ceramic with a low melting point. The shell of the core-shell particles has a second ceramic with a low melting point and a low dielectric constant. The core-shell particles are sintered and molded to form a low-k material. The shell of the core-shell particles is connected to form a network structure of a microcrystal phase.

Abstract: A door handle with electronic lock assemble comprises a door handle and a connecting rod. The door handle is deposited on a side of a door. The connecting rod is rotatable mounted on the door handle by crossing through the door. The door comprises a lock operatively connected with the door handle and the connecting rod. The door handle comprises an electronic module mounted therein. The electronic module comprises a controller, an actuator module and an electronic key interface. The controller and the actuator are signal connected. The electronic key interface is electronic connected with the controller.
