Abstract: An outer roll stop for a wheelchair lift includes a base having a leading end, a trailing end, a top surface, and a bottom surface positioned opposite from the top surface, a top plate secured to the base, with the top plate moveable relative to the base, and an interlock assembly comprising a sensor positioned between the top plate and the base, with the sensor having a first state and a second state. The sensor moving from the first state to the second state when an object is positioned on the top plate. The sensor is configured to detect when an object is positioned on the top plate prior to motion of the outer roll stop.

Abstract: When swaying motions of a trailer or semi-trailer of a car-trailer combination are encountered, input signals which are taken into consideration to calculate a reference signal frequently include also oscillation components, due to which driving dynamics control for stabilization of the car-trailer combination can become very unreliable. To enhance the reliability of driving dynamics control of this type, a method is disclosed in which an input signal (Y) is sensed that includes signal oscillations which are due to a swaying motion of the trailer or semi-trailer and are superimposed on a base component (YBasis) of the input signal (Y). A reference signal is calculated from the input signal (Y), in which case the calculation is executed in such a way that the reference signal by approximation corresponds to a reference signal which is determined from the base component (YBasis) of the input signal (Y).

Abstract: Systems and methods for accumulating air in an auxiliary reservoir of a railroad car are disclosed. In some embodiments, the method may include charging an air brake system. Air pressure in the air brake system may reach a predetermined value. Once this predetermined value is reached, additional or excess air may be bled from the air brake system and the additional or excess air may accumulate in an auxiliary reservoir. The auxiliary reservoir may be adapted to supply air to an auxiliary cylinder or other types of pneumatic components or equipment.

Abstract: A bus door/service brake interlock system having a warning system is provided. The interlock system includes a foot valve assembly to effect a service brake application when warning lights are activated, a vehicle door is open, and minimum speed conditions are met. An auxiliary line is positioned between a source of pressure and the foot valve assembly and includes a valve and a low pressure indicator. Should the operator leave the driver seat with the interlock system engaged, the parking brake is automatically applied.

Abstract: A bus door/service brake interlock system having a warning system is provided to inform a driver that the service brake pressure is insufficient or not being applied at all, as well as indicating if a system malfunction occurs, precluding a service brake application. The system is based on a sequential operation of the driver activating the caution lights and opening the door. Once these events have occurred, the autobrake system including an alarm is activated. On the other hand, applying the park brake deactivates the autobrake system. The autobrake assembly energizes a solenoid that receives regulated pressure from a pressure reducing valve. This pressure is supplied to one side of a double check valve, while the other side receives a delivery from the foot valve to assure delivery for normal service braking.

Abstract: An apparatus for communicating information over a pressurized fluid-carrying pipe connecting a plurality of serial nodes. A sounder node (i.e., transmitter) creates variable pressure patterns within the fluid-carrying pipe, which pressure patterns are identified and detected by other nodes. The patterns convey information or solicit responses from the receiving nodes. The receiving nodes reply to the pressure fluctuations by inducing reply pressure fluctuations in the fluid-carrying pipe or by communicating with the sounder node via a separate radio frequency communications system. The apparatus and method can be used as an information-carrying communications medium or a train linking methodology for a railroad train.

Abstract: A side brake device, wherein a pivot of a lever (5) is pivotally supported rotatably on a fixed plate (3) located at an operator's seat side, a side brake wire (2) is fixed to one end of the lever and the one end of an elastic body (7) is fixed to the other end of it, the lever is energized by the elastic body so that it is always rotated in the direction to apply a side brake by pulling the side brake wire, a side brake lever (1) is installed so that it can be rotated by a fixed amount relative to the lever, a wire (10) is passed from one end of the side brake through the other end of the lever to an appropriate position of a door, and the lever is rotated downward against the energizing force of the elastic body so as to loosen the side brake wire and release the side brake, the lever is held by a holding means at the lever releasing position, holding by the holding means is released by the opening of the door or upward manual rotating operation of the side brake lever, and the lever is rotated in the

Abstract: A vehicular slide door apparatus includes a slide door which opens and closes an opening formed in a lateral side of a vehicle body. A brake device is provided at the lateral side of the vehicle body to apply a braking force to the slide door to adjust or control the speed of movement of the sliding door.

Abstract: A vehicular slide door apparatus includes a slide door which opens and closes an opening formed in the lateral side of the vehicle body 2. A brake device is provided at the lateral side of the vehicle body to apply a braking force to the slide door. The brake device is under the control of an electronic control device.

Abstract: An emergency brake lock assembly that locks an emergency brake actuator in an engaged position to prevent the vehicle from moving while a lift assembly contained on the vehicle is being operated. The emergency brake lock assembly includes an emergency brake switch that is positioned to detect movement of the emergency brake actuator between an engaged position and a disengaged position. When the emergency brake actuator is in the engaged position, the emergency brake switch generates a brake engaged signal. An auxiliary door switch is positioned to detect the movement of an auxiliary door contained on the vehicle. When the auxiliary door opens, the auxiliary door switch generates a door open signal. Upon receiving both the door open signal and the brake engaged signal, a solenoid actuator moves a locking member to a locked position to retain the emergency brake actuator in the engaged position.
