Abstract: Disclosed are a method and a traffic routing system for controlling traffic flows in which hazardous or special material is transported through safety-critical traffic zones such as tunnels, bridges or locks. In the method and traffic routing system, safety-relevant data is read with the help of a signal transmitter disposed on the transported hazardous or special material and is transmitted to a central computer unit when said vehicle passes reading devices located in the safety-critical traffic zone. The central computer unit determines a safety risk in the safety-critical traffic zone on the basis of the safety-relevant data of all transported hazardous or special material located in the safety-critical traffic zone and sets traffic routing signals.

Abstract: The present embodiments relate to checking a validity of a time-limited status of a device. In one embodiment, a checking unit includes an RFID reader and a control unit. The control unit is embodied for performing a validity check that relates to a time period and is based on time information read by the RFID reader from an RFID label and conveyed to the control unit.

Abstract: An input device interacts with a terminal device and/or controls the terminal device of a communication network. The terminal device serves to receive and to transmit a content data stream which represents a chat transmission. In addition, the terminal device functions to transmit messages created by the input device to a processing unit of the communication network. The input device has at least one sensor for determining a physical state of an operator of the input device. The input device is furthermore designed to transmit a value representing the physical state to the terminal and/or the processing unit.

Abstract: In the method for quantitative evaluation of agglutination reactions between a reagent and a biological fluid to be examined, the reagent and the biological fluid are intimately mixed by a horizontal circular movement. The agglutinates formed in the mixture while the circular movement is maintained are optically imaged thereafter on a ground glass plate, and the image is evaluated using an electronic evaluation device.
