The disclosure relates to a drive arrangement for movement of a tailgate, wherein at least one drive unit is provided, having two drive connections, wherein a first drive unit is motor and spring-operated and has a drive unit motor as well as a drive unit spring, respectively acting on the two drive connections associated with the first drive unit, wherein the first drive unit comprises a movement sensor, representing movement information regarding a movement between the drive connections, wherein a second drive unit is spring-operated and has a drive unit spring, acting on the two drive connections associated with the second drive unit, wherein a drive unit controller is provided, which detects a predetermined deviation of the sensor signal of the movement sensor from a predetermined normal signal corresponding to the normal condition as an error condition and upon detecting an error condition carries out an error routine.

A movable barrier operator transmits a message to a remote peripheral platform and, upon determining that the remote peripheral platform is presently able to carry out a given functionality, responsively permits a particular function to be carried out by the movable barrier operator. Conversely, upon determining that it cannot be ascertained whether the remote peripheral platform is presently able to carry out the given functionality, the movable barrier operator responsively prevents the movable barrier operator from carrying out the particular function. Also, upon detecting that a targeted remote platform does not acknowledge a previously re-transmitted message and further upon detecting that this same remote platform has also not acknowledged a subsequent wirelessly-transmitted second message, the system can switch to automatically retransmitting that second message a lesser number of times than would otherwise be required.

A package delivery system for an automated delivery management of one or more packages is provided. The package delivery system may include a package locker unit and a control network. The package locker unit includes at least one adjustable access point, at least one pallet tower and at least one adjustable door assembly slidably. The at least one pallet tower includes a plurality of adjustable racks. The adjustable door assembly slidably coupled to the at least one pallet tower and defines an adjustable access point to access the package from the respective pallet of the respective rack. The control network is configured to facilitate customized automatic operation of the at least one adjustable door assembly while loading and delivery of the one or more packages.

A household appliance includes a door pivotable via door hinges and having an electrical load. A treatment chamber has a loading opening which is closeable by the door. An energy transmission device has a primary side including a primary coil which is attached to a stationary part of a respective one of the door hinges, and a secondary side including a secondary coil which is arranged on the door and is electrically connected to the electrical load. The primary coil is capable of being coupled in a manner of a transformer to the secondary coil when the door is closed.

A slide-and-swing wing system includes at least one rail profile. At least two wings, each displaceably mounted in the at least one rail profile via two support elements The at least one rail profile has a lateral outlet opening for unlatching a support element of a wing. One wing functions as a door leaf which, with all other wings in the latched state, is pivotable into the remaining opening. A closure mechanism makes it possible to prevent the door leaf from being opened and includes a drive, and also an operating part, via which the drive can be actuated. The door leaf is displaceable, via the drive, in the rail profile in the direction of the adjacent wing to such an extent that no support element of the door leaf is aligned with the outlet opening, thereby preventing a support element from coming out through the lateral outlet opening.

A saloon-type door assembly that includes left and right door assemblies that each include a frame adapter having a curved inner surface with a first apex, a front portion and a rear portion, a door adapter that includes a curved outer surface with a second apex a front portion and a rear portion, a door panel associated with the door adapter, at least one front hinge strip secured along a front hinge strip path, and at least one rear hinge strip that is secured along a rear hinge strip path. The front hinge strip path extends from the front portion of the curved outer surface of the door adapter to the rear portion of the curved inner surface of the frame adapter. The rear hinge strip path extends from the rear portion of the curved outer surface of the door adapter to the front portion of the curved inner surface of the frame adapter. The door panels are movable between a front open position, a closed position and a rear open position.

The present invention relates to a door operator (1) and to a method performed in a door operator system (100) comprising a door operator (1) connected to and arranged to move at least one door leaf (5) between an open and closed position, the door operator (1) comprising a control unit (3) configured to control the movement of the at least one door leaf (5), the method comprising: obtaining (S100), in a sleep mode of the door operator system (100), a sequence of input data in one or more components of the door operator (1) or the at least one door leaf (5), receiving (S110), in the control unit (3) of the door operator (1), said sequence of input data from the one or more components, and evaluating (S120) said sequence of input data and ranking (S130) the probability of that said sequence of input data corresponds to an intrusion attempt on the door operator system (100).

This disclosure relates to a system and method for isolating an interior of a motor vehicle from poor outdoor air quality. More particularly, this disclosure relates to a system and method configured to identify conditions associated with poor outdoor air quality and to respond to those conditions by isolating the interior of the motor vehicle from the outdoor environment. An example system includes a selector configured to permit a user to select a drive mode of the motor vehicle, a location system configured to detect a location of the motor vehicle, and a controller configured to issue one or more commands to isolate an interior of the motor vehicle from an environment outside the motor vehicle based on either a selected drive mode or a detected location.
