A system, method, and device for operations of an electrically motorized vehicle. The vehicle can utilize an electrically motorized wheel to convert a non-motorized wheeled vehicle to an electrically motorized wheeled vehicle. One system is a physical therapy system including a prescription module to prescribe a physical therapy prescription for operation of the device of the electrically motorized wheel and a rehabilitation application in communication with the prescription module to calculate the set of control parameters based on the physical therapy prescription.

A wall mounting apparatus includes a container defining a mounting hole therein, a lock device received in the container, and a connector engaging with the container and the lock device to assemble the container on a determined position stably. The lock device includes a driver, an electrical connector electrically connecting the driver, and an engaging plate driven by the driver. A recess is defined in the engaging plate. One end of the connector is mounted on the determined position, and the other end thereof extends through the mounting hole and supports the container. The electrical connector is turned off to make the driver drive the engaging plate moving towards the connector to make the connector insert in the recess of the engaging plate and be clasped by the engaging plate.

A lock management system manages access to a controlled environment by locking or unlocking a door. The lock management system can actuate one or more components of a lock system to lock or unlock the door. To determine whether to lock or unlock the door, the lock management system can establish a connection with one or more devices. The lock management system can receive an access credential via the connection and authenticate the access credential. Based on authenticating the access credential, the lock management system can lock or unlock the door. The lock management system can monitor a door status and/or door activity and provide alerts to a user computing device.

An electronic cylinder that can be actuated by an electronic key, wherein said electronic cylinder includes a stator body, a rotor, a motor that can be actuated by the electronic key, a clutch mechanism configured to lock and unlock the rotation of the rotor with respect to the stator body by means of the actuation of the motor, and a system for detecting rotation of the rotor with respect to the stator body, said system being configured to deactivate the motor when the rotor rotates with respect to the stator body. To this end, the clutch mechanism includes two locking balls which are elements that move radially inside the cylinder, to lock and unlock the rotation of the rotor) with respect to the stator body, said rotation of the rotor being carried out by the electronic key.

A switching device for delayed unlocking function, disposed at a flat-push type emergency door-lock device having a flat-push rod, including a switching-device base, a pushing swing arm, a linkage rod, a sensing assembly, a timing control assembly and an electromagnetic traction assembly. The pushing swing arm is disposed at the switching-device base and includes a stopper, being switchably maintained at an avoidance position in a delayed unlocking function disabled state and preset at a stop position in a delayed unlocking function enabled state. The timing control assembly starts timing when the sensing assembly senses the flat-push rod is pushed, and it makes the electromagnetic traction assembly to drag the pushing swing arm to cause the stopper to move from the stop position to the avoidance position after the timing reaches a predetermined delay time. When the stopper is at the avoidance position, the flat-push rod is avoided to allow the flat-push rod to continue to be pushed to complete unlocking.

A method of implementing a network-enabled secure door lock, comprising obtaining measurements of an environment associated with a door from a variety of sensor types; generating, based at least in part on the measurements, a set of inputs to a machine-learning model; inputting the set of inputs into the machine learning model to determine a status of the door; generating a message that indicates the status of the door; and transmitting the message to a user device.
