An apparatus comprises a baseplate configured to be coupled to a door movable between an open position and a closed position. A motor with circuitry electrically coupled to the motor, and configured to be in communication with a remote computing device. At least one proximity sensor is electrically coupled to the circuitry and configured to determine the door position with respect to a door frame. A drive wheel is coupled to the motor and the circuitry. The drive wheel has an external surface, and the external surface of the drive wheel is configured to rotatably contact a ground surface. The motor is configured to be remotely activated by the remote computing device to actuate the drive wheel to rotatably contact the ground surface to reposition the door responsive to receipt of a signal.

The embodiments herein provide a secure package delivery and pick-up system. The system comprises a security door with several collapsible storage compartments for accommodating packages meant for delivery or pick-up. The size of the compartments are configured to accommodate packages of different sizes and weights. The system enables secure delivery and return pick-up of packages at unmanned location by using security measures such as electronic key generation, biometric identification, RFID, video cameras. The user is facilitated to monitor the delivery and pick-up activity remotely through a mobile application downloaded on the computing device. The system is easy to install and provides protection of the packages form theft or damages due to weather conditions. The system enables user to share secure electronic keys with other users for a predetermined duration for accessing the building through the secure door and for usage of the storage compartments.

Systems and methods to indicate whether a safe is locked or unlocked.

A vehicle-mounted display device includes a switching mechanism disposed in the slide door and having a support frame on which a display screen is fixed. The support frame is switchable between a display-folded position in which the display screen is folded and a display-unfolded position in which the display screen is unfolded; and a door-open detector that detects whether a door-open command signal indicating that the slide door is going to be opened is received. When the door-open detector receives the door-open command signal, the support frame is switched from the display-unfolded position to the display-folded position, a screen surface or a back surface of the display screen and the inner side of the slide door are facing each other in the left-right direction in the display-folded position, and the display screen is in the display-folded position at least when the slide door is in the door-opened position.

The present disclosure includes a haptic guidance and navigation system for a vehicle that includes two Blutooth modules configured as beacons (using, for example, Bluetooth®, Low-Energy (BLE) modules) disposed on the front-center end and back-center end of a vehicle. The system may include an application operative on a mobile device that is also configured for BLE. The BLE modules onboard the vehicle may be uniquely associated with the vehicle with a unique identification (ID), and used to determine relative distances and angles between the BLEs and the mobile device. The haptic guidance and navigation system may generate haptic and other feedback using the mobile device and haptic output devices onboard the vehicle, to guide a user to a determined point of entry for the vehicle.

During operation of the door system one or more sensors may be utilized in order to monitor the operation of the door assembly (e.g., door system, door, frame, etc.), review the operating parameters, troubleshoot potential issues, schedule and monitor service requests, review and take actions for potential security threats, and/or the like. Consequently, users may determine if the door system operates the door in accordance with the desired operating parameters by reviewing the movement, vibration, speed, acceleration, force, or the like based on the sensor information captured and use the information to adjust the door assembly. Notifications regarding the operation of the door systems may be sent automatically and/or in response to requests from users. The users may utilize one or more applications and interfaces thereof to remotely connect to the door systems in order to review and analyze the sensor information and take the desired actions.

A movable barrier operator system including a movable barrier operator configured to be connected to a movable barrier and move the movable barrier. The system includes a remote control configured to utilize a first security protocol to wirelessly transmit a communication to the movable barrier operator and cause the movable barrier operator to move the movable barrier. The movable barrier operator is configured to receive information representative of a second security protocol and to eliminate a compatibility of the movable barrier operator with communications from the remote control utilizing the first security protocol.

A variable air hole covering flap device is provided and selectively opens or closes an air hole formed in a wheel deflector or a wheel cover to allow air to be introduced toward a brake. The air hole is opened only when brake cooling of a vehicle is more necessary than aerodynamic performance of the vehicle to properly control the aerodynamic performance and the brake cooling performance of the vehicle as necessary.
