Abstract: An optical projector module to establish distance to target object in a field of view for three dimensional image acquisition purposes includes a printed circuit board, point light sources mounted on the printed circuit board to emit a plurality of light beams, a lens unit apart from the plurality of point light sources, and a distance adjusting unit connected to the lens unit. A memory storage device is also included. The lens unit comprises separated lenses, the adjusting unit can adjust distances between the lenses of the lens unit, and light beams with a number of light spot patterns can accordingly be projected. Previously-captured images in the memory storage device can be referred to in seeking target objects in the field of view and light beams in different spot-concentrations on or around the target object enable calculations for the capture of images in three dimensions of the target object.

Abstract: A mechanical shutter includes a base including a plate with an aperture and a protruding positioning projection. A core on the surface surrounds the aperture and includes a first end and a second end. The positioning projection is arranged between the first end and the second end, on one corner of the surface. A coil surrounds the core and a blade and a permanent magnet are pivoted on the positioning projection. When receiving current, the coil magnetizes to the core to generate a magnetic force and rotates the permanent magnet, and the blade, to cover and expose the aperture. An electronic device having the mechanical shutter is also provided.

Abstract: A mechanical shutter includes a base, a cover, a primary blade and a secondary blade. The base includes a first through hole and a connecting shaft extending from the base. The cover includes a second through hole and a connecting hole. The connecting shaft of the base extends through the connecting hole to secure the cover to the base. The first through hole is coaxial to the second through hole, thereby cooperatively forming an light passage. The primary blade and the secondary blade are moveably interconnected so when the primary blade rotates around the connecting shaft relative to the base, the primary blade carries the secondary blade to move, and the secondary blade moves together to cover or expose the light passage.

Abstract: An exemplary mechanical shutter includes a base with a through hole defined therein, a blade arranged on the base, two shape memory alloy units, and a control unit. Each of the two shape memory alloy units includes a first end and a opposite second end. The first end of the shape memory alloy element is attached to the base, and the second end is attached to the blade. The control unit is configured for controlling the two shape memory alloy units to selectively deform into a first shape, or into a second shape. In particular, the two shape memory alloy units each straighten to a first shape (straight shape) and move the blade to cover the through hole. In addition, the two shape memory alloy units each deform to a second shape (spring coil shape) and thus move the blade away from the through hole to expose the through hole.

Abstract: An electronic device includes a main body, a lens received in the main body, and a collapsible lens cover with one end fixed on the main body and the other end capable of resisting or detaching from the main body such that the lens is covered or uncovered.

Abstract: An exemplary mechanical shutter includes a barrel, a first blade, a second blade, a third blade, a magnet, and a magnetic field generator. The barrel defines a through hole and an aperture in the hole. The first blade is arranged in the hole and mounted on the barrel. The second blade is slidably mounted on the first blade. The third blade is slidably mounted on the second blade. The magnet is attached to the third blade. The magnetic field generator is mounted on the fixture and spatially corresponding to the magnet. The magnetic field generator applies a magnetic field to the magnet. The magnet and the magnetic field generator cooperatively move the blade group between an extended position and an retracted position.

Abstract: An exemplary vehicle seat system includes a vehicle seat, an electronic control unit, a crash detection unit connected with the control unit, a seat occupancy sensing module configured for sensing an occupancy of the seat and generating a digital signal associated therewith, an airbag, and an airbag inflating module. The detection unit detects a crash and sends a crash signal associated therewith to the control unit. The inflating module is selectively operable in an activated mode where the inflating module is configured to inflate the airbag in response to the crash signal and an inactivated mode where the inflating module is deactivated and irresponsive to the crash signal. The control unit analyzes the digital signal and determining if the vehicle seat is occupied, and switches the inflating module either in the activated mode if the seat is occupied or in the inactivated mode if the seat is not occupied.
