A vehicle is provided that includes a vehicle body, a plurality of RF signal receivers located at a plurality of locations within the vehicle, an RF signal transmitter configured to be located on a pet for transmitting an RF signal, and a controller for processing the RF signal received by each of the plurality of RF signal receivers and determining a location of the pet based on the received RF signals, wherein the controller generates an output based on the location of the pet and controls at least one vehicle function based on the output.

The invention relates to a refinement of a spindle drive (1), and to a louvered window or a louvered shutter having a spindle drive for moving louver elements such that applied return forces and return torques can be absorbed better, and in particular without placing a load on the drive motor. For this purpose, the spindle drive (1) has a specially designed return stop mechanism (6) arranged between a drive shaft of a drive motor (3) and a threaded spindle (4).

A door assembly of a vehicle includes a first door panel movable at least partially across a door opening from a first side of the door opening toward a second side of the door opening, a second door panel spaced apart from the first door panel and movable at least partially across the door opening from the first side toward the second side. A first magnetic element is located at the first door panel and a second magnetic element is located at the second door panel. The second magnetic element is interactive with the first magnetic element such that moving of the first door across the door opening causes movement of the second door panel across the door opening.

A louvre shutter comprising louvres 20 rotatably mounted in a frame on louvre axles, and a louvre drive system that, in summary, comprises a rack and pinion gear system including an externally operable rack assembly and a set of pinion gears 28 mounted to the louvre axles. The rack is externally operable rack and is reciprocably mounted in the drive system housing 42, 48. The pinion gears 28 mounted to the louvre axles are engaged with the rack such that reciprocation of the rack rotates the louvre 20 relative to the frame.

Electro-mechanical and electronically controlled access devices are described for automatically controlling passage between two areas, and where a plurality of such access control devices may be ganged or clustered to provided additional throughput and directional control, including stacking a plurality of access control devices side by side within a cluster. Each access control device contains multiple rotatable and moveable door panels. The door panels are controlled by various drive mechanisms to enable passage through the device, while ensuring by the use of sensors that door panels avoid touching subjects as they traverse the device. The direction of flow through a device according to these embodiments is electronically controlled and may be changed from time to time. At any instant in time while being traversed, the flow through each device is unidirectional. Multiple devices within a cluster can be directionally controlled according to traffic, demand, time of day, or other factors.

A milking arrangement includes a milking module having at least two milking places, a front gate assembly, a sequence gate assembly, an entrance gate, an independent first drive device for moving the front gate assembly between lower and upper positions, and a second drive device for moving the entrance gate between open and closed positions. An independent third drive device moves the sequence gate assembly from a first position to a second elevated position in which the sequence gates are located at a level above and behind animals standing in respective milking places. The sequence gate assembly being configured to move from the second position to the first position such that the sequence gates urge animals standing in their respective milking places to leave the milking places. A control arrangement controls opening of the entrance gate on basis of the position of the sequence gate assembly.

A spindle drive, a spindle nut for the spindle drive, and a louvre window or louvre shutter having a spindle drive for moving louvre elements. The spindle nut is constructed in multiple parts including a screw nut part, having an internal thread to engage on an external thread of the threaded spindle, and a bearing part in which the screw nut part is mounted. The screw nut part includes a driver structure for transmitting a drive force applied by the threaded spindle to the spindle nut onto an element to be driven. Furthermore, the screw nut part is rotatably mounted in the bearing part in such a way that the screw nut part executes a relative movement in relation to the bearing part, and a directional component of the movement is transverse to a thread longitudinal axis of the internal thread.

A versatile door system for an aircraft includes forward and aft door assemblies. The forward door assembly includes a forward hingeable door hingeably coupled to the airframe proximate a forward location of an aircraft opening and a forward slidable door slidably coupled to the forward hingeable door. The aft door assembly includes an aft hingeable door hingeably coupled to the airframe proximate an aft location of the aircraft opening and an aft slidable door slidably coupled to the aft hingeable door. In a closed configuration, the forward hingeable door, the forward slidable door, the aft hingeable door and the aft slidable door are securably disposed within the aircraft opening. In operation, the forward hingeable door, the forward slidable door, the aft hingeable door and the aft slidable door are individually operable to collectively provide access to a selectable width of the aircraft opening.

The opening-closing control system includes an outputter that outputs a control signal for controlling an operation of an opening-closing member configured to open and close an opening provided in a first facility, and an obtainer that obtains alert information on an alert from a second facility different from the first facility. Then, the outputter outputs the control signal for controlling the opening or closing of the opening by the opening-closing member based on the information.
