Abstract: A lock includes a latch assembly, a first locking mechanism, a second locking mechanism, a linkage mechanism, a clutch mechanism, and a rebounding mechanism. The lock utilizes a first clutch member and a second clutch member of the clutch mechanism to coordinate with a leaning portion of an inner linkage member of the linkage mechanism to achieve that when the turned inner linkage member will outward push the first clutch member and the second clutch member away from each other to make the second clutch member rapidly and accurately be engaged with an outer linkage member of the linkage mechanism so as to make the outer linkage member to drive the latch assembly to unlock. The arrangement provided by the present invention that has the first clutch member and the second clutch member coordinate with the leaning portion of the inner linkage member simplifies the entire structure of the lock.

Abstract: An electronic lock cylinder contains: a receiving sleeve, a lock head, a fastener, a rotation element, a rotatable actuation element, a driven element, a drive motor, a resilient element, an operation element, a locking element, and a locating cap. Thereby, the drive motor moves clockwise or counterclockwise to drive the rotary column to rotate 90 degrees and to simultaneously actuate the driven element, the drive motor, the resilient element, and the engagement projection of the operation element to move forward or backward to rotate or rotate idly in the notch of the locking element, thus saving energy and obtaining environmental protection.

Abstract: A transmission structure of a rotary shaft of an electronic lock contains: a drive unit which includes a holding plate, a motor, a worm, and a driven wheel. The holding plate includes an externally threaded portion and a fixing orifice. The driven wheel includes an internally threaded orifice, two protrusions, two flat zones, two arcuate fringes, and a tooth section. The transmission unit includes a guide element, a movable element, a resilient element, a retainer, and an acting element. The guiding element has a central orifice, the movable element has a guiding orifice, and the acting element has a slidable post. The frame includes a defining orifice and is welded with the holding plate. The connection seat is received in the defining orifice and includes a retaining portion. After the connection seat is received in the defining orifice, the retaining portion is engaged with a fastening ring.

Abstract: A switch structure for a lock deadbolt contains: a body, a sliding device, a shifting element, and a flexible buffer. The body includes two bases having a fastener and a connection portion. The two bases have an actuation section, a slide space, a receiving room, two slots, two first orifices, four second orifices, and a positioning zone. The sliding device includes a slidable segment, an extending sheet, a groove, and two wings. The slidable segment has a coupling portion. The shifting element includes a rotary shaft, a cross-shaped trench, a swing column, a rotatable seat, two abutting faces, and a connecting area of the two abutting faces is a contacting edge. The flexible buffer is located on the positioning zone of the two bases, and the flexible buffer includes a cushion portion, two flexible holders, two flexible chambers, and two support feet.

Abstract: An electronic lock control structure having smart photography contains: a first lock and a second lock. The first lock includes a central processing module, a memory storage device, and an image interface The memory storage device has a receiving slot for receiving a memory card. The first lock further includes a locking member having a rotatable lever rotatably connected with a connection member on the first lock, and the connection member has a coupling stem and a fastener. The central processing module, the memory storage device, and the image interface are connected to form an input circuit. The second lock includes a connecting segment, an application (APP) controlling module for controlling mobile application (APP), an electrical bell, a photography controlling module, and a voice controlling module. The electrical bell, the photography controlling module, and the voice controlling module are electrically connected to form an electrical circuit.

Abstract: A method, system and computer-readable medium for obtaining a temperature profile of a wellbore is disclosed. Raw temperature data are obtained from the wellbore using a distributed temperature sensing system. The raw temperature data includes noise. A numerical decomposition is performed on the raw temperature data within a dynamic window in a measurement space of the raw temperature data to obtain decomposition terms of order of first order and higher. An adaptive filter is applied to the decomposition terms of first order and higher within the dynamic window to reduce noise from the decomposition terms of first order and higher. The filtered decomposition terms of first order and higher are used to obtain a temperature profile of the wellbore.
