Abstract: A semiconductor structure includes a substrate, and an active device and a passive device over the substrate. The active device is disposed in a first region of the substrate, and the passive device is disposed in a second region of the substrate. The semiconductor structure further includes a shielding structure and a passivation layer. The shielding structure includes a barrier layer and a ceiling layer. The barrier layer is on the passive device and the active device, and the ceiling layer is on the barrier layer. The passivation layer is under the barrier layer and covers a top surface of the passive device. An air cavity is defined by sidewalls of the barrier layer, a bottom surface of the ceiling layer, and the substrate.

Abstract: A lock device includes a latch and inner and outer operating devices disposed on two sides of the latch device. The inner operating device includes a main board configured to control the outer operating device to or not to move a latch between the latching position and the unlatching position. The outer operating device includes a removable input interface module electrically connectable with the main board. The input interface module is configured to permit input of an unlocking identification information or an unlocking command by a physical or wireless measure.

Abstract: An auto-latching latch assembly is mounted to a follower door of a double door. The latch assembly includes a latch movable between an unlatching position and a latching position and a movable member jointly movable with the latch. A positioning member is jointly pivotable with the movable member. When the latch moves to the unlatching position, the positioning member positions the latch in the unlatching position. When the follower door is closed while a primary door of the double door is closed, an actuation latch presses against and releases the positioning member to move the latch to the latching position, reliably locking the follower door.

Abstract: An electric door lock includes an operating device and a latch device operably connected to the operating device. An inner electronic device, an outer electronic device, and an electric driver are electrically connected by an electrical connecting module. An inner fixing member and an outer fixing member are fixed to a door. The inner fixing member includes an inner groove through which a first cable extends. The outer fixing member includes two first grooves. A second cable selectively extends through one of the two first grooves according to an assembling direction of the door. Thus, no matter whether the electric door lock is mounted to a left handed-door or a right-handed door, the electrical connecting module can avoid the mechanical structure of the electric door lock, providing convenient assembly.

Abstract: An auto-latching latch assembly (10) is mounted to a follower door (275) of a double door (257). The latch assembly (10) includes a latch (231) movable between an unlatching position and a latching position and a movable member (50) jointly movable with the latch (231). A positioning member (911) is jointly pivotable with the movable member (50). When the latch (231) moves to the unlatching position, the positioning member (911) positions the latch (231) in the unlatching position. When the follower door (275) is closed while a primary door (259) of the double door (257) is closed, an actuation latch (131) presses against and releases the positioning member (911) to move the latch (231) to the latching position, reliably locking the follower door (275).

Abstract: A door latch device includes a positioning seat having a positioning portion mounted to a top end or a bottom end of a door. The positioning portion includes a sliding groove having a sidewall with first and second insertion grooves. An actuation block includes a head and a body. The body is slideably received in the sliding groove. The body includes a receptacle. A ball is received in the receptacle of the actuation block and is biased by a spring. A latch is fixed to and jointly moveable with the actuation block between a latching position and an unlatching position corresponding to the locations of the first insertion groove and the second insertion groove. When the latch is in the latching or unlatching position, the spring biases the ball into a corresponding one of the first and second insertion grooves to retaining the latch in the latching or unlatching position.

Abstract: A latch assembly with an anti-picking function includes a bracket mounted in a door and located at a top or bottom end of the door. A movable member is slideably received in the bracket. A lever is pivotably mounted in the bracket. A positioning member includes a first pivotal portion pivotably connected to the movable member. The positioning member and the movable member can move jointly. The positioning member further includes a second pivotal portion pivotably connected to the lever. When the lever pivots, the positioning member pivots and actuates the movable member to move, causing movement of a latch between a latching position and an unlatching position. When the latch is in the latching position, a lug of the positioning member abuts against the movable member to prevent the latch from moving from the latching position to the unlatching position by picking.

Abstract: A latch assembly (10) is mounted to a follower door (275) of a double door (257) and includes a latch (231) and a pressing board (453) pivotably received in a cutout (411) of the latch (231). When the follower door (275) moves from an open position to a closed position, a pressing side (457) of the pressing board (453) is pressed by a top beam (35) of a door frame (31). The pressing board (453) pivots and presses against a bottom face (413) of the cutout (411) of the latch (231), moving the latch (231) from an unlatching position to the latching position until the pressing side (457) of the pressing board (453) completely enters the cutout (411), and then a slant face (236) of the latch (231) presses against the door frame (31), causing movement of the latch (231) from the latching position to the unlatching position.

Abstract: A fire bolt assembly (10) includes a receiving tube (117) mounted in a door (106). A mounting member (32) is mounted to the receiving tube (117). A positioning bolt (151) is received in the receiving tube (117). A stop member (58) is securely mounted in the mounting member (32) to hold the positioning bolt (151) in the receiving tube (117). The front end (153) of the positioning bolt (151) is moved out of the receiving tube (117) by a spring (100) to engage with a coupling hole (116) in another door (112) or a door frame when the stop member (58) melts due to the heat of a fire, locking the door (106) in place during the fire. A stick (175) in the receiving tube (117) is moved to a blocking position preventing the front end (153) of the positioning bolt (151) from disengaging from the coupling hole (116).

Abstract: A latch assembly (10) is mounted to a follower door (275) of a double door (257). When the follower door (275) is closed while a primary door (259) of the double door (257) is closed, an actuation latch (131) of the latch assembly (10) is moved from a releasing position to a pressing position to move a latch (231) of the latch assembly (10) to a latching position engaged in a groove (37, 300) in a door frame (31) or in the ground (299). When the actuation latch (131) is moved from the releasing position to the pressing position while the follower door (275) is not in the closed position, the latch (231) is retained in an unlatching position, avoiding damage to the latch assembly (10).

Abstract: An anti-pick latch assembly (10) is mounted to a follower door (275) of a double door (257). The latch assembly (10) includes an actuation latch (131) normally extending beyond an end face (291) of the follower door (257) and a latch (231) movable between an unlatching position received in the follower door (275) and a latching position extending out of the follower door (275) into a groove (37) in a door frame (31). When the follower door (275) is closed while a primary door (259) of the double door (257) is closed, the actuation latch (131) is actuated to move a limiting member (90) to a locking position, moving the latch (231) of into the groove (37) of the door frame (31). The limiting member (90) in the locking position prevents the latch (231) from moving out of the groove (37) while the latch (231) is picked.

A lever includes a lug received in the receiving space. The lug has a pin hole through which the second pivot extends. When the lever pivots from an upper position to a lower position about a pivot axis defined by the second pivot, the push member pivots about a pivot axis defined by the first pivot for unlocking operation.
