摘要： A mobile power system may include a bidirectional AC-DC converter configured to convert a grid AC signal to a power limited DC charging signal with a threshold level, a battery module configured to provide a DC power signal, and a controller coupled to the battery module and the bidirectional AC-DC converter and configured to selectively switch the bidirectional AC-DC converter between a first state and a second state. The first state may include, when a load power level is less than the threshold level, concurrently charging the battery module using the power limited DC charging signal and delivering the grid AC signal to a load. The second state may include, when the load power level is greater than the threshold level, concurrently converting the DC power signal with the bidirectional AC-DC converter into a battery AC signal for delivery to the load, and delivering the grid AC signal to the load.

摘要： A method for monitoring a pantograph. The method includes acquiring an impulse response of the pantograph, extracting a natural frequency and a damping coefficient of the pantograph from the impulse response, obtaining a similarity factor of a plurality of similarity factors, and detecting a fault in the pantograph from the plurality of fault types based on the plurality of the similarity factors. Acquiring an impulse response of the pantograph includes generating the impulse response by tapping the head of the pantograph and recording the impulse response utilizing a recording equipment.

摘要： A current collector for a non-track-bound, electrically driven vehicle for feeding electrical energy from a two-pole overhead line system with two contact wires. Two upper arms are rotatably connected to an adjustable lower arm by toggle joints. Each upper arm carries a contact rocker for contacting the contact wires. Coupling bars are rotatably connected to the upper arms and articulated so that adjustment of the lower arm forces adjustment of the upper arms. A compensating rocker compensates for a height difference between the contact rockers with a rocker stand and a rocker beam. The rocker stand can be rotatably connected to the vehicle and the rocker beam is connected to the coupling bars by way of compensating joints on either side of the rocker joint. At least one stop element limits a rotational movement of the rocker beam about a rocker joint axis of the rocker joint.

摘要： A vehicle is provided that comprises two or more radio frequency (RF) antennas and two or more RF transceivers to communicate wirelessly sensitive information associated with a user of the vehicle (the two or more RF antennas being at different physical locations on an exterior of the vehicle). The vehicle determines which one of the two or more RF antennas is receiving a strongest signal from a common signal source, selects a first RF transceiver associated with the RF antenna with the strongest signal to send the sensitive information associated with the user to the common signal source, and sends the sensitive information associated with the user to the first RF transceiver for transmission to the common signal source.

摘要： A rail installation has an overhead line in the region of a stop and at least one rail vehicle with a current collector for making contact with the overhead line. The overhead line has a central part having a limited, predefined length and an adjoining end portion. The central part has a substantially constant predefined height above a rail. The end portion has a height that increases outward from the central part. The current collector of the rail vehicle is raised and matched to the overhead line such that, as the rail vehicle enters the stop, sliding strips of the current collector have a height above the rail that is at least equal to the substantially constant height of the central part of the overhead line, and that is at most equal to the greatest height of the raised first end portion of the overhead line above the rail.
