A method for operating a storage-and-retrieval unit (3) is specified, in which a rail line (1)/power-supply rail (6) is set to a hazard-operation voltage when a risk posed by the storage-and-retrieval unit (3) is detected. In the storage-and-retrieval unit (3) the level of the voltage applied to the rail line (1)/power-supply rail (6) is measured and a current path between the rail line (1)/power-supply rail (6) and a drive motor (5, 5a . . . 5c) of the storage-and-retrieval unit (3) disconnected when the voltage measured is below a threshold value associated with a hazardous situation or emergency. Furthermore, a storage-and-retrieval unit (3) as well as an automated rack storage system for performing the proposed method is specified.

The invention relates to an arrangement (100) for active alignment control of a contact element (110) of a charging device (104) for a vehicle (1) for driving on an electrical road system (ERS) comprising a charging surface (3) configured to provide electrical power to the vehicle via the charging device. The arrangement comprises the charging device (104) comprising a base (106), a linkage arm (108), and an electrical contact element (110) and a pivot joint (107) arranged for allowing a movement of the contact element around an axis (105). A control unit is configured to activate an actuator module to align said contact element (110) with said trajectory of said charging surface based on trajectory data and an angle between the vehicle heading and the charging surface. The invention further relates to a method and to a vehicle.

Embodiments include apparatus and methods for implementing lane charging for a roadway. A road segment in a geographic region is identified from a geographic database. The road segment may be identified based on the geographic position of a vehicle. A lane charging management device receives real time data related to the vehicle, the environment, or the electricity associated with the charging station. A lane charging command for a charging device associated with the road segment is generated in response to the real time data.

This invention is for an inexpensive and cost-effective way to patrol and prevent un-authorized personnel from entering or crossing a special one-way roadway. By having continuous surveillance, with the patrol-vehicles having photo equipment, infra-red equipment, radio equipment for contacting proper authority, and having a siren equipped vehicle, it is unlikely for un-authorized personnel from entering or crossing the one-way roadway.

The road way is having a left and right fence, preferably made with transparent panels, allowing for visual and infrared surveillance. This surveillance allows for instant detection of any un-authorized person or equipment,

The preferred patrol is with a vehicle that is electric and driverless. Signage stating of an addition of an electrified wire, similar to animal-prevention-fence prevents personnel from entering the roadway.

A collected current monitoring device is provided which includes a current-value obtaining unit that obtains a current value I1 and a current value I2, a first RMS-calculation unit that calculates a root mean square RMS1, a second RMS-calculation unit that calculates a root mean square RMS2, an Iu calculation unit that calculates an imbalance current Iu, a change calculation unit that calculates an amount of change Iu, an average calculation unit that calculates a time average value aveIu, a determining unit that determines whether the time average value aveIu is larger than a threshold value, and a signal output unit that outputs an abnormality signal when the time average value aveIu is larger than the threshold value.

An equipment asset may include a body, one or more current collector rails, and a grounding element. The body may have a top side and a power transfer zone. The power transfer zone may include at least an electrically non-conductive top surface. The one or more current collector rails may be mounted to the top side of the body within the power transfer zone. The grounding element may be electrically conductive and disposed on the top side of the body. The grounding element may surround the power transfer zone and be spaced apart from the one or more current collector rails. The grounding element may receive liquid that is runoff from the power transfer zone and electrically ground charged portions of the liquid.
