Abstract: A method and system for monitoring the operation of a wind energy installation. State data relating to the wind energy installation is recorded and discrepancies are found between the state data and an associated comparison value. A failure probability of the wind energy installation is determined based on any found discrepancy. An availability value for the wind energy installation is determined from the ratio of the actually produced amount of electrical energy to the total amount of energy which can potentially be produced. The availability value and the failure probability are then combined to form a repair priority, which is associated with the wind energy installation. Accordingly, more uniform operation of wind energy installations can be achieved.

Abstract: An indicator for enabling an analytical instrument to positively detect the presence of a vial in respective vial-receiving rack position regardless of whether the vial is oriented in a manner necessary for a code reader to read a code printed on the vial. Translation of a leaf spring upon insertion of a vial into a rack position causes a flag to obscure a code provided adjacent the rack position. An instrument into which the rack is installed interprets the failure of the code reader to detect this code as positive indication that a vial is disposed within the respective rack position.
