    Abstract: A dot matrix projector includes an infrared light source used to emit infrared light, a collimating lens, a semi-transparent and semi-reflective plate on an output side of the collimating lens, a diffractive optical element on an output path of the semi-transparent and semi-reflective plate, and an infrared light conversion film on another output path of the semi-transparent and semi-reflective plate. The collimating lens is used to receive the infrared light from the infrared light source and collimate the infrared light to be parallel infrared light. The semi-transparent and semi-reflective plate is used to divide the parallel infrared light into a first part directly transmitting the semi-transparent and a second part being reflected by the semi-transparent and semi-reflective plate. The infrared light conversion film is configured to convert infrared light into visible light. A facial recognition module and an electronic device are also provided.

    Abstract: A broken pipe extraction device includes first, second, and third pressure plates, a fixing member, a fastening member, and a needle. The first pressure plate includes a first perforation and a second perforation connected to the first perforation. The second perforation passes through a side wall of the first pressure plate. The second pressure plate faces the first pressure plate. Projecting portions of the first perforation and the second perforation on the second pressure plate overlap. The third pressure plate includes a through hole. The third pressure plate is detachably received in the first perforation and the second perforation. The fixing member mounts on the second pressure plate and faces the first perforation and the second perforation. When the third pressure plate is received in the first and second perforations, the through hole faces the fixing member.

    Abstract: A multi-lens camera module making use of a single image sensor comprising first and second lens modules, an image acquisition module, a refracting module, and a shielding module. The refracting module refracts light from either the first lens module and/or the second lens module, the shielding module allowing light to enter only one of the first or second lens modules by masking the other. The first and second lens modules can share one image acquisition module, which saves cost and interior space of the camera module and thus of the electronic device using such camera module. An electronic device comprising the camera module is also provided.

    Abstract: A calibration device includes a base, a support column coupled to the base and extending in a first direction, and a crossbar coupled to the support column. The crossbar includes a positioning base and a carrier. The positioning base is fixed to the support column. The carrier is coupled to the positioning base and rotatable about a second direction perpendicular to the first direction. The carrier includes a distance sensor and a calibration platform. The calibration platform mounts a depth camera. The carrier is configured to rotate about the second direction to rotate an optical axis of the depth camera in a first calibration plane defined by the first direction and a third direction. The third direction is perpendicular to the first direction and the second direction.

    Abstract: A focusing device includes a fixing base, a screw rod, a focusing gear, a height adjusting ring, and a focusing ring. A first through hole is defined in the fixing base, the screw rod with a first thread is movably mounted on the fixing base. The focusing gear is also mounted on the fixing base and defines a third through hole corresponding to the first through hole. An outer wall of the focusing gear has an engaging portion meshing with the first thread. The focusing ring is movably received in the third through hole and located on a side of the height adjusting ring away from the fixing base. The height adjusting ring can adjust a distance between the focusing ring and a lens module to avoid distortion of an optical lens in any circumstances during focusing.
