The base includes a front end and a rear end opposite to each other in an axial direction, and an outer peripheral wall connected therebetween. The plural stator magnetic poles are arranged on the base. The circuit board controls the plural stator magnetic poles. The first elastic element disposed on the outer peripheral wall includes a first head end, a first middle section and a first tail end connected and extended sequentially in a direction surrounding the axial direction. The second elastic element disposed on the outer peripheral wall and has a second head end, a second middle section and a second tail end connected and extended sequentially in a direction parallel to the axial direction.

Abstract: A door lock device includes a spring latch rotatably and movably disposed within a housing to be pressed to rotate and move between a projecting position, where the spring latch projects outwardly of a latch hole of the housing, and a retreated position, where the spring latch retreats inwardly into the latch hole. A retaining member is pivotably disposed to the housing, and is operable to rotate between a retaining position to engage with the spring latch to prevent rotation of the spring latch in the projecting position, and a releasing position to disengage from the spring latch. A biasing spring is disposed to bias the retaining member to the retaining position and to keep the retaining member in the retaining position.

Abstract: A magnetic door lock includes a door lock kit and a door frame lock kit. The door lock kit includes a deadbolt having a retaining slidable sleeve disposed in a deadbolt guiding slot in a housing, and a magnet disposed in the sleeve. The deadbolt is operable to slide between a locking position, where a retaining end of the sleeve projects outwardly from the housing, and an unlocking position, where the retaining end retreats into the slot. A driving member is operable to drive the deadbolt to slide from the locking position to the unlocking position. The door frame lock kit includes a lock frame and a magnet which is magnetically attracted to the magnet to urge the deadbolt to slide into the lock frame in the locking position.

Abstract: A control system for an electronic lock includes a control module. The electronic lock has a locked state and an unlocked state. The control module is configured to communicate with a portable device for receiving an unlock request 5 that includes a digital signature and a request identifier therefrom. The control module includes a processing unit and a storage electrically connected to the processing unit. The storage stores a key and a registered identifier. The processing unit is configured to, in response to receipt of the unlock request, verify the digital signature using the key, in response to successfully verifying the digital 10 signature, determine whether the request identifier matches the registered identifier, and in response to determining that the request identifier matches the registered identifier, control the electronic lock to switch from the locked state to the unlocked state.

Abstract: A method for manufacturing light-shielded cameras includes forming a plurality of camera dies by dicing a camera wafer stack including (a) an image sensor wafer having a plurality of image sensors, (b) a cover glass bonded to the image sensor wafer, and (c) a lens wafer bonded to the cover glass and having a plurality of lenses, to form a plurality of camera dies. The method further includes, prior to the step of dicing, (i) from a first side of the image sensor wafer facing away from the cover glass and at least partly covered by an opaque layer, pre-cutting a sensor-cover wafer stack that includes the image sensor wafer and the cover glass, and (ii) depositing an opaque material in the pre-cuts. The method also includes, after the step of dicing, applying an opaque coating to second-side surfaces, of the camera dies, formed by the step of dicing.

Abstract: A ventilation apparatus includes a main body, an air entry and an air exit respectively arranged on two sides of the main body, a filter arranged behind the air entry, and a pressure sensor module located between the filter and the air exit, which senses pressure caused by air flowing inside the main body through the air entry and the filter. The pressure sensor module firstly senses pressure related data when the apparatus begins to start for initial data, and senses pressure related data continuously after the apparatus starts for working data, and transmits these data externally. An analysis monitor device computes a reference pressure offset value and a working pressure offset value according to the initial data and the working data, and compares the two pressure offset values for determining whether the filter needs to be replaced.
