Abstract: An automatic clean device for a surveillance camera has an automatic cleaner. The automatic cleaner is connected to the surveillance camera directly or via an angle adjusting mechanism and has a housing, and an operating assembly, a driving assembly and a cleaning assembly mounted in the housing. The driving assembly drives the operating assembly to move linearly and turn. The cleaning assembly is mounted on the operating assembly and cleans a lens of the surveillance camera. The cleaning head is not disposed in front of the lens and is disposed away from the lens when the automatic cleaner is not executing its cleaning task. Thus, the cleaning head does not obstruct the surveillance camera so the surveillance camera is able to film complete images.

Abstract: An electronic lock includes: an elongated lock case formed to have an opening, and formed thereinside with a bobbin-receiving space and a first passage; an annular bobbin with a middle passage, and disposed such that the middle passage is coaxially and spatially communicating with the first passage to serve as a second passage; a coil being operable to generate a magnetic field inside the second passage; a driving body configured such that when the magnetic field is generated by the coil, the driving body is repulsed by the magnetic field to move toward the opening; a latch body configured such that when the coil generates the magnetic field, the latch body is driven to move from an unlatching position to a latching position; and a spring for storing a restoring force when the latch body moves from the unlatching position to the latching position.

Abstract: A light-filtering module for an image-capturing device includes a casing, a sliding filter unit, and an actuator unit. The casing is formed with an aperture in spatial communication with a slide groove. The sliding filter unit includes a lens set slidable in the slide groove between a first position, where a first lens component is aligned with the aperture, and a second position, where a second lens component is aligned with the aperture. The actuator unit includes an electromagnetic coil set and an armature unit having a magnetic rod portion connected to the sliding filter unit and extending movably into an armature hole in the electromagnetic coil set. By energizing the electromagnetic coil set, the armature unit can be driven for moving the lens set to a selected one of the first and second positions.
