A door operation management system (100), method and computer program product for controlling operation of a door (1), the door operation management system (100) comprises at least a first movement sensor device (10a, 10b, 10c) arranged at the door (1), for determining a movement of the door (1); and a processing circuitry (102a, 102b) operatively connected to the at least first movement sensor device (10a, 10b, 10c) configured to cause the door operation management system (100) to obtain at least a first sensor data (dd1, dd2, dd3, dd4) from the at least first movement sensor device (10a, 10b, 10c); and determine at least a first state (st1, st2, st3, st4) of the door (1) based on the at least a first sensor data (dd1, dd2, dd3, dd4).

A fenestration assembly includes a fenestration frame and at least one panel movable between open and closed positions. A locking mechanism is coupled with the at least one panel and includes at least one latch and at least one latch fastener. The panel includes a secure configuration with the panel in the closed position and the latch coupled with the latch fastener. In the unsecure configuration one or more of the panel is in the open position or the latch is decoupled from the latch fastener. A status monitoring assembly monitors the secure and unsecure configurations and includes a sensor operator coupled with the latch, and a sensor coupled with one of the fenestration frame or the panel. In the secure configuration, the status monitoring assembly detects the sensor operator with the sensor if the panel is in the closed position and the latch is coupled with the latch fastener.

A device may be provided for preventing fatal bathroom accidents relating to falls. Such a shower fall prevention device may be attached to a fixing point on a ceiling of a shower and may have two arm pit hooks pivotably connected to the fixing point. It may further comprise a rod connected between the fixing point and a bar, where arm pit hooks may be connected on right and left ends of the bar. The device may further comprise a strong rubber band or an extendable and retractable belt, connected between the fixing point and the rod. The device may further comprise a handle next to the rod and connected to the bar via an extension of a free end of one of the arm pit hooks, and may further comprise a cushion formed on an extension of a free end of one of the arm pit hooks.

An intelligent door lock system is coupled to a door at a dwelling. A sensor is at the dwelling. The sensor being 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 sensor and includes a bolt. An engine, an energy source and a memory are coupled together. A camera is coupled to the intelligent door lock system with a wide field of view.

An energizable electromagnet of a door locking system is affixed to the door or the door frame for electromagnetically attracting an armature affixed to the other. A power control circuit is configured to selectively energize the electromagnet using a pulse-width modulated current cycle wherein two levels of magnetic force may be selectively applied to the system. A door position sensor is configured to provide a first communication signal to the power control circuit when the door is in a closed position. A second communication signal is provided when the door is not in the closed position. The electromagnet is energized at the lower level of magnetic force when the power control circuit receives the first communication signal and at the higher level of magnetic force only when an unauthorized attempt to open the door is initiated.

A sensor system to reliably alert and inform a user of the status of a window, in particular, a sensor system which reliably informs the user if the window is both in a closed position and also that the locking mechanism is in the locked configuration. There are thereby provided two independent sensor systems within the casement window handle assembly which are arranged to verify that the window handle is in the locked configuration and also that the window sash is in the closed position relative to the window frame. The casement window handle assembly comprises a first sensor for indicating the position of the window handle and this comprises a first sensor component mounted to the pivotal/movable handle and a second component fixed within the mounting base.

A refrigerator locking system is used to secure the doors of a refrigerator in closed or open positions. The system includes at least one anchor bar, a locking bracket, a door block and a refrigerator. The refrigerator includes a frame, at least one refrigerator door and a freezer door. The anchor bar is mounted to the frame in between the refrigerator door and the freezer door. The locking bracket is connected adjacent to the frame and is engaged with to the door block to secure the refrigerator door and the freezer door. The door block can be used to press the refrigerator door and the freezer door against the frame, keeping the refrigerator closed. Alternatively, the door block can be positioned in between the frame and both the refrigerator door and the freezer door to keep the refrigerator open.

A control method includes controlling a lever, a pusher and a motor so as to arrange the same in a correct position when electric power is supplied to the home appliance, or the user turns on the home appliance. Abnormalities involving an automatic opening of the door through changes in a return/stop switch and an opening sensing switch while the motor operates so as to open the door may be confirmed.

An intelligent door lock system provides notification of energy source status. A position sensing device is configured to be coupled to a drive shaft of a lock device. The position sensing device sensing position of the drive shaft assists in locking and unlocking a lock of a lock device. An engine with a memory is provided, with the engine coupled to the positioning sensing device, and a circuit coupled to the engine. An energy source is coupled to the circuit. A server is associated with the intelligent door lock system and provides notification of energy source status.

The invention relates to an electronic lock that defines an open position and a closed position and includes a mobile carriage moveable in a linear manner. The mobile carriage is coupled to a closure element and to an actuation mechanism. A first spring is provided between the mobile carriage and the closure element and is configured to move in relation to the mobile carriage. A lock sensor is provided for controlling the position of the closure element. An electronic control module is connected to the sensor for identifying non-authorised manipulations of the lock when it should be closed. The lock sensor detects when the closure element is in the open position or, if it should be open, the lock sensor does not detect when the closure element is in the open position.
