Abstract: Methods of conducting generative language training using a training corpus having a plurality of words and a plurality of stimuli are described. A stimulus is presented via an electronic display. A selection is received from visual representations of a plurality of the words represented on the display. It is determined whether the selected words correspond to the represented words in the stimulus. A mastery level can be determined based on correspondence of the responses and stimuli and the training corpus or sequence modified based on the mastery level. Another method includes receiving mastery-level data for multiple learners and determining a training sequence using relative difficulties determined from the mastery-level data. Another method includes determining a proficiency level using the correspondence of responses and, if the determined proficiency level corresponds to an intervention criterion, performing an intervention sequence including detecting word selections and unlocking inputs.

Abstract: In a method for cleaning a liquid delivery device such as a dispensing or pipetting device, the liquid chamber can be flushed in a cleaning step. To remove gas bubbles which might exist in the liquid chamber, for example, the liquid in the liquid chamber is vibrated during the cleaning step.

Abstract: In a method for monitoring the operability of a liquid delivery device such as a dispenser (10), a response signal of a liquid-transformer system consisting of a transformer (24) and a chamber (12) containing a liquid is compared with a reference value. Preferably, the reference value is determined when the liquid-transformer system is operative, i.e., non-disturbed. The response signal differs from the reference value if there are air bubbles in the chamber (12), for example. By comparing the response signal with the reference value, a correction step such as a cleaning cycle can be performed when a limit value is exceeded or fallen short of.

Abstract: The dispensing of sample liquids is performed, particularly in case of high-throughput screening, by means of automatic dosing devices. Between individual dosing processes, the standstill of the dosing device may lead to an outgassing of the sample liquid existing in the dosing device, and to crystallization. In order to improve the operational safety, it is provided according to the method of the invention that a stand-by routine is initiated after termination of a dosing process. In the stand-by routine, liquid is dispensed via a dosing orifice of the dosing device. The dispensing step is repeated after a predetermined period of time.
