The present invention relates to the field of IgE-mediated allergy, particularly occupational asthma such as bakers asthma. Each hanger has an attachment section which is shaped like a cane and a clothes section on which clothes are hung. The arrangement can be run in a normal mode, with all of the memory elements 30 in a high resistance state so that the matrix display can be driven dynamically. The method provides, inter alia, means for accurately aligning the hoof capsule with the coffin bone in the hoof. The processor performs the subsequent processing operations. The restart control unit includes threshold-value setting unit, and the threshold value corresponding to a characteristic to be input to the threshold-value setting unit is preset.
