An intelligent door lock system is coupled to a door at a dwelling. A first sensor is at the dwelling. The first sensor is coupled to a drive shaft of a lock device to assist in locking and unlocking a lock of a lock device at a door. The lock device is coupled to the first sensor and the lock device includes a bolt. An engine, an energy source and a memory are coupled together. A magnetic sensor provides a reading or measurement used to determine a door open or closed status.

A security tag includes a tag body member, a connecting member releasably engageable with the tag body member, and a locking member having a locked position in a first thermal state configured to lock the connecting member to the tag body member, and having an unlocked position in a second thermal state configured to unlock the connecting member from the tag body member. The locking member includes a locking body comprising a shape memory alloy, and a clamping member connected to the shape memory alloy. A transition of the shape memory alloy element from the first thermal state to the second thermal state moves the clamping member from the locked position to the unlocked position, thereby enabling the connecting member to be detached from the tag body member.

A storage device (10) for storing a key, the storage device (10) comprising a housing (12, 38); a blocking structure (40); a carrier (18) for carrying 76 a key, the carrier (18) being movable relative to the housing (12, 38) between a closed position (20), in which the carrier (18) is accommodated within the housing (12, 38), and an open position (26), in which the carrier (18) at least partly protrudes from the housing (12, 38) for retrieval of a key from the carrier (18), the carrier (18) comprising a blocking member (44) and a biasing device (42) arranged to bias the blocking member (44) into engagement with the blocking structure (40) in the closed position (20); and an actuator (52) comprising a locking structure (54), the actuator (52) being arranged to move the locking structure (54) between a 40 locking position (56) to lock the blocking member (44) when engaging the blocking structure (40), and an unlocking position (84) in which the blocking member (44) is not locked by the locking structure (54).

Disclosed is a lock actuation assembly for actuating a lock of a door. Prior to first commanding a motor to rotate a key in the key hole a controller of the lock actuation assembly is configured to: receive an indication that a key holder is disposed to have the key at least partially inserted into the key hole; determine a rotational position of a key holder receptacle relative to a mounting portion of the lock actuation assembly from the indication by a position encoder; and store, in an electronic data storage, the rotational position as an initial insertion/extraction position at which the key is insertable to, and extractable from, the key hole.

An electric lock, comprising: a case combining with a side plate and a case cover; a latch bolt, a latch bolt shaft and a latch bolt spring, the front end of the latch bolt shaft is combined with a blocking member, and the blocking member uses the elastic force of the latch bolt spring to stick out of the side plate to lock, when the external force applied to the latch bolt shaft is sufficient to resist the elastic force of the latch bolt spring, the blocking member will retract into the side plate to unlock; a unlock crank, having an electric push member, and a push member relative to the latch bolt shaft; and a linear actuator and an actuating arm, the front end of the actuating arm is combined with a push block relative to the electric push member, and a push block return spring is set relative to the push block.

Security systems and methods are provided. In one example, a security system includes at least one lock configured to protect one or more items from theft from a fixture, and a strike plate configured to be mounted to the fixture. The lock comprises a plunger pin configured to be moved between a locked state when in engagement with the strike plate and an unlocked state when disengaged from the strike plate, and the lock comprises a cam configured to move the plunger pin between the locked state and the unlocked state. The lock is configured to be moved between a latched position and an unlatched position while the lock is in the unlocked state, the fixture configured to be accessed in the unlatched position, and the strike plate is configured to move relative to the lock to align the lock with the strike plate when the lock is moved from the unlatched position to the latched position.

A washing machine includes a housing equipped with an inlet, a door to open or close the inlet and including a latch with a locking hole formed at the latch, a door locking device including a locking member with a locking bar formed at the locking member to be inserted to the locking hole, and configured to lock or unlock the door according to whether the locking member is fixed, an automatic door opening device to deliver driving power to the locking member so that the locking bar is removed from the locking hole, and a controller to control the door locking device to unlock the door by unfixing the locking member, in response to a completion of a washing course and to control the automatic door opening device to open the door by delivering the driving power to the locking member in response to the door being unlocked.

Security systems and methods are provided. In one example, a security system includes at least one lock configured to protect one or more items from theft from the fixture, wherein the lock comprises a plunger pin configured to be moved between a latched position and an unlatched position, and wherein the fixture is configured to be accessed in the unlatched position. The lock comprises a cam configured to be moved between a locked state and an unlocked state for allowing the plunger pin to be moved between the latched position and the unlatched position when in the unlocked state, wherein the cam is configured to be moved in response to receiving a wireless authorization signal to transition the lock between the locked state and the unlocked state.

A circuit for a smart lock includes a state detection unit, a main control chip and a motor driving unit, the state detection unit includes optocoupler sensors U21, U31 and a Hall sensor; the optocoupler sensor U21 is configured to form a first in-position signal, the optocoupler sensor U31 is configured to form a second in-position signal, the Hall sensor is configured to detect whether the state of the lock body is unlocked in position so as to form an auxiliary signal; the main control chip is configured to output a control signal according to the first and second in-position signals and the auxiliary signal; and the motor driving unit is configured to drive the motor to rotate forward or reverse or stop rotating according to the control signal.

Securing systems and methods of securing a transport container to an attachment point. In one embodiment, the securing system includes an actuator, an attachment structure, and an electronic controller. The attachment structure is dimensioned to complement the actuator. The electronic controller is operably coupled to the actuator for attaching and releasing the actuator to the attachment structure.
