Abstract: An elevator car includes at least one elevator door, a door drive for actuating the elevator door, a sensor for detecting the motor power of the door drive and an evaluating unit that determines, based on the motor power detected, whether there is a deviation in the drive force actuating the elevator door from a reference drive force. The evaluating unit determines whether a deviation occurs due to an obstacle in contact with the elevator door or due to altered external conditions, particularly due to altered pressure conditions and/or air flow.

Abstract: A system for controlling temperature of an energy store in a motor vehicle may include a coolant circuit in which a coolant may be flowable and into which the energy store may be incorporated in the thermally conductive manner, a refrigerant circuit in which a refrigerant may be flowable and including a refrigerant compressor, a flat tube condenser, and a receiver dryer, which may be secured in the flat tube condenser, and a refrigerant evaporator connecting the coolant circuit and the refrigerant circuit. Heat between the coolant and the refrigerant may be transferrable in the refrigerant evaporator. The system may be secured in a housing.

Abstract: A system for controlling a temperature of an electrical energy storage device may include a coolant circuit through which a coolant is flowable, a refrigerant circuit through which a refrigerant is flowable, a first coolant cooler, a support structure, and at least one molded component. The coolant circuit may be thermally coupled to the electrical energy storage device such that heat is at least one of (i) absorbable from the electrical energy storage device via the coolant and (ii) dissipatable to the electrical energy storage device via the coolant. The refrigerant circuit may be configured as part of a heat pump. The first coolant cooler may be configured to transfer heat between the coolant and the refrigerant. The at least one molded component may be structured separately from the support structure and may include a foamed plastic.

Abstract: A holder structure fixed to an elevator car of an elevator is configured to hold a passenger's smart mobile device. The mobile device includes sensors, and the holder structure releasably mechanically couples the mobile device to the elevator car. A method for monitoring an operation of the elevator includes providing the mobile device with a specific application software controlling the mobile device to execute the following monitoring procedure: repeatedly supervising measurement values of at least one of the sensors; upon occurrence of a specific parameter pattern in the measurement values, starting a measurement acquisition procedure during which measurement values are sensed by at least one of the sensors and the sensed measurement values are transmitted to an evaluation unit for further evaluation. The specific parameter pattern specifically results upon the mobile device being held in at least one of a predefined position and a predefined orientation in the elevator car.
