Abstract: A system having electric consumers includes an electrical device including an operating device and wires supplying the consumer. A first wire is provided for conducting the first phase of a three-phase voltage during a normal operation, a second wire conducts a second phase of the three-phase voltage, and a third wire conducts a third phase of the three-phase voltage. The consumer is able to be supplied with the three-phase voltage from the wires during a normal operation. The operating device is configured so that: in a normal operation, the first wire is connected to the first phase of the three-phase voltage; and in a safety case, the first wire is separated from the first phase of the three-phase voltage and will be or is connected to the second phase of the three-phase voltage.

Abstract: A current collector for a non-rail-bound, electric traction vehicle has an articulated support linkage, which, on the contact wire side, supports rocker assemblies with contact strips and, on the vehicle side, has a base joint for articulation to the traction vehicle. A pneumatic reciprocating drive is coupled to the support linkage for raising the rocker assemblies from a lower parking position into an upper contact position when the reciprocating drive is pressurized and for lowering into the parking position under its own weight when depressurization occurs. An exhaust air line connects the reciprocating drive to the environment to lower the rocker assemblies. An air accumulator and a downstream throttle valve are connected between the reciprocating drive and an environment opening of the exhaust air line. The rocker assemblies can be quickly lowered and nevertheless brought into the parking position without damage in order to disengage the current collector.

Abstract: An example charging station for an unmanned aerial vehicle (UAV), the charging station generally including a nest and a charging device. The nest includes an upper portion and a lower portion. The upper portion defines an upper opening sized and shaped to receive a landing apparatus of the UAV, and a diameter of the nest reduces from a first diameter at the upper opening to a second diameter at the lower portion. The charging device is mounted in the nest, and includes a first contact pad and a second contact pad. The charging device is configured to apply a voltage differential across the first contact pad and the second contact pad such that the charging station is operable to charge a power supply of the UAV via the landing apparatus.

Abstract: An unmanned aerial vehicle according to certain embodiments generally includes a chassis, a power supply mounted to the chassis, a control system operable to receive power from the power supply, at least one rotor operable to generate lift under control of the control system, and a motor operable to lower a free end of a line. The free end of the line is operable to engage a parcel to be delivered by the unmanned aerial vehicle. The control system is configured to operate the motor to cause the free end of the line to accelerate toward a delivery surface as the free end of the line passes through a first portion of a distance between the unmanned aerial vehicle and the delivery surface, and to decelerate as the free end of the line passes through a lower portion of the distance.

Abstract: A quick charging system for electrically driven vehicles and method for forming an electrically conductive connection between a vehicle and a stationary charging station having a contact device, a charging contact device, and a positioning device. The charging contact device can be electrically contacted in a contact position together with the contact device. The contact device can be positioned in the vertical and horizontal direction relative to the charging contact device and moved to the contact position. The contact device has a contact element carrier with contact elements that can each be electrically contacted together with charge contact elements of the charge contact device, forming contact pairs, in the contact position. A guide device is provided, such that, when the contact device and the charge contact device are brought together, a physical contacting of the contact elements together with the charge contact device is inhibited before reaching the contact position.
