Abstract: Disclosed is a method for determining a possible bacterial infection in a patient exhibiting symptoms selected from specific internal symptoms of disease, and/or diffuse and general manifestations of disease, and/or is a blood donor. The method includes: i) determining a) the level of a Rickettsia analyte in a sample 1 from a patient exhibiting symptoms, possibly combined with b) the level of a Borrelia analyte in a sample 2 from the same patient; ii) considering that the symptoms exhibited by the patient involve a) rickettsiosis if the level of the Rickettsia analyte in sample 1 is elevated, and b) borrelios if the level of the Borrelia analyte in sample 2 is elevated. For blood donors step, (ii) means that whole blood and blood fractions are considered to be infected with Rickettsia and/or Borrelia, respectively, when these levels are elevated. Also disclosed is a corresponding kit.

Abstract: The invention concerns a method for controlling the operation of an actuator unit, comprising the steps: a) repeatedly reading the current fed to the actuator unit, b) a first comparison wherein the readings are compared with a first maximum level and if the readings are above the maximum level the electrical power fed to the actuator unit is cut off, c) a second comparison wherein two successive readings repeatedly are compared with each other and if the differences between the readings are below a first ramp level a number a steady state condition for the current fed to the actuator unit is detected, and d) if steady state is detected setting at least one overload detection limit on basis of a steady state reading of the current fed to the actuator unit. The invention also concerns a device for carrying out the method and a conveyor incorporating the device.
