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.

A door assembly includes a door, a door actuator mechanism configured to transition the door between an open position and a closed position, a first latch configured to hold the door in the closed position, and a second latch engaging with a portion of the door actuator mechanism and being configured to hold the door in the closed position. The second latch includes a cam and a biasing member coupled to the cam. The biasing member is configured to transition the cam between a first position in which the cam engages the portion of the door actuator mechanism, and a second position in which the cam disengages the portion of the door actuator mechanism.

A railcar hatch control system and method for operating railcar hatches of a multi-railcar train is disclosed. A multi-railcar train may have a locomotive and a plurality of railcars having railcar hatches that can be opened and closed. The system and method may include displaying railcar identification information for the railcars on an operator display device, and receiving selections of railcars from an operator that will have a railcar hatch operation performed thereon, such as opening or closing the hatches. The railcar hatch operation is input, and the system and method control the railcar hatch operation being performed only on the selected railcars, and not on the railcars that have not been selected by the operator. The system and method may have operator interfaces devices at an operator station of the train, or at a remote location or on a remote device that communicates wirelessly with the train.

A track-guided power door operator used to simultaneously open a set of opposing hinged doors is disclosed. The door operator comprises a pair of articulated arm linkages, each pair of which is pivotally mounted at One end to a vertically oriented pivot pin at one end of a guide member and pivotally connected at the other end to a vertically oriented pivot pin of a yoke member of a translating carriage, which is engaged by a horizontal lead screw. Translation of the carriage member due to rotation of the lead screw causes lateral separation between the knuckles of the articulated arm pairs to cause doors contacted by the knuckles to rotate about their respective hinges. The door operator may include a control unit to control operation of the doors. The operator may further include magnetic latches to lock the doors closed.

A device for coordinated control and operation of double doors having a plate with a rectilinear motion that is associated with links with adjustable lengths that connect the plate to the double doors, with both the first and the second doors opened when one of the doors is opened and sequentially closed when one of the doors is closed.

A sliding apparatus for a sliding door comprises: a front top roller part including an upper outer bracket and an upper inner bracket; a front bottom roller part including a lower outer bracket and a lower inner bracket which are fitted and fixed to both lower ends of the front door while being connected to each other by a lower connecting bar, and are formed to slide in both lateral directions after moving forward; a rear roller part including rear outer brackets and rear inner brackets which are formed at both upper ends and both lower ends of a rear door formed on one side of the front door, so as to slide the rear door; a front rail part including guide rails which are formed on the upper and lower end surfaces of a rear door frame and the upper and lower surfaces of the rear inner bracket.

A device for coordinated control and operation of double doors having a plate with a rectilinear motion that is associated with links with adjustable lengths that connect the plate to the double doors, with both the first and the second doors opened when one of the doors is opened and sequentially closed when one of the doors is closed.

A sliding window assembly including a window frame and at least three panes disposed within the window frame in offset vertical planes. The panes are arranged for sliding movement together upwardly within the window frame or together downwardly within the window frame. One or more of the panes can be fixed. The panes have a fully open position and a fully closed position. In the closed position, respective edges of the panes overlap while in the open position, the entire panes overlap. The panes can be connected to a counterweight arrangement by a pulley arrangement, which includes a vertically movable balancing weight that is equal to the weight of the panes, or the panes can be connected together to counterbalance each other.

A plant shield assembly includes an elongated shield having a first door operably connected to a second door and both doors are pivotally connected to the vehicle and movable between an open position and a closed position. The plant shield assembly includes a door opening mechanism operably attached to the elongated shield and configured to move the first and the second doors. The plant shield assembly includes a linkage assembly that connects the elongated shield with the door opening mechanism, and limits the extent of rotation of the doors. The door opening mechanism and linkage assembly are positioned between the elongated shield and the vehicle. The door opening mechanism can be a handle attached to the elongated shield. Optionally, the plant shield assembly includes an access door that is disposed between an open position to enable actuation of the handle and a closed position to block actuation of the handle.
