A door system for a public transit vehicle includes at least one door opening and a door that closes this door opening, wherein a sensor unit performs three-dimensional and touch-free scanning of a passenger compartment in the area of the door opening. A process of monitoring and controlling such a door system includes the steps of touch-free and three-dimensional scanning of a passenger compartment in the area of a door opening with a sensor unit, and measuring distances, shapes, and movements of objects by evaluating the readings from touch-free and three-dimensional scanning.

Door system with sensor unit for contactless passenger compartment monitoring

A door system for a public transit vehicle with at least one door opening and a door that closes this door opening includes a sensor unit, which does three-dimensional and touch-free scanning of a passenger compartment in the area of the door opening and at least one communication element for the context-based communication with passengers based on readings by the sensor unit. A process for monitoring and controlling door systems of a public transit vehicle are also provided including the steps of touch-free and three-dimensional scanning of a passenger compartment in the area of a door opening with a sensor unit and measuring distances, shapes, and movements of objects by evaluating the readings of the touch-free and three-dimensional scanning. The process also includes issuing context-based information to affected passengers via a communications system, whereby the information is based on readings from the sensor unit. A process for monitoring and controlling such a door system.

A drive device for embarkation and disembarkation devices of public transportation vehicles includes a drive unit arranged within and for driving a rotary column. The drive unit rotates the rotary column about the rotary column longitudinal axis Z-Z during opening and closing processes of the embarkation and disembarkation devices. The drive device is supported on the vehicle. The drive unit includes a drive motor, a non-self-locking reduction gear, and a controllable blocking component with which a rotation of the rotary column can be blocked. The drive device further includes a sensor for detecting the magnitude of an external force, wherein the force acts on the drive device. The drive device further includes an element for analyzing signals of the sensor and for triggering the blocking effect of the blocking component when an external force measured by the sensor exceeds a threshold.

A drive system for an entry/exit facility with at least one pivotably and/or slidably mounted door, ramp, tread or the like of a passenger transport vehicle, the system including at least one actuator or drive motor and a mechanical system driven by it and/or a gear unit for effecting the pivoting or sliding movement of the door, ramp, tread or the like, with an absolute value encoder for acquiring a momentary position during the pivoting or sliding movement, where an evaluation unit is configured to compare the momentary position with at least one reference position stored in a non-volatile memory of the evaluation unit in order to generate an output signal dependent thereon, and the absolute value encoder is flange-connected to a pin that fixes the pivoting movement of the door, ramp, tread or the like, and the gear unit includes a first reduction gear unit, a second reduction gear unit, and a controllable coupling is provided between the reduction gear units.

The present invention provides a flow meter whereby movement of fluid causes screw spindles or other movable elements to rotate and generate electronic pulses. The invention compensates for non-linearity in the relationship between the flow rate and the number of pulses, occurring particularly at low flow rates, by providing a device in the form of a transducer which assigns volume a value to each pules, which volume values are accumulated such that when certain predetermined value is exceeded a transducer generates a counter signal. Thus, the present invention enables compensation for non-linearity to be made and pulses output corresponding to a standard unit of volume.
