Abstract: A phase controller device according to the invention comprises a hardware core that is formed by a signal detector, a voltage-controlled oscillator, a phase comparator, and an integration unit, where the hardware core, by controlling the working clock pulse frequency of the microcontroller, brings an output clock pulse signal that is generated by a microcontroller into phase with the input clock pulse information that is received from the input data stream, and does so in such a manner that the jitter is low. The microcontroller executes a program with this working clock pulse, where with that program the microcontroller generates the output clock pulse signal with an output clock pulse frequency that is in a predetermined division ratio to the control clock pulse frequency that is generated by the voltage-controlled oscillator and is given to the microcontroller as a working clock pulse frequency.

Abstract: A freely traversable metering head with numerous metering devices, wherein the metering devices are each provided individually or block-by-block with an activating device, and wherein a controller traversable with the metering head is designed for the independent operation of one or more activating devices. Metering devices for such a metering head and procedures for their use are also disclosed.

Abstract: The invention relates to a method for transferring, for instance, a biological material arranged in a given pattern, whereby the biological material is brought into contact with needles placed on the head of a robot and the biological material is transferred to a support, whereby the needles are hard metal needles fitted with a biocompatible coating. The biocompatible coating preferably consists of metal-nitrogen compounds. Preferably, an anticorrosion coating is applied underneath the biocompatible coating. Once the biological material has been arranged in a given pattern, the needles mounted on the robot head are arranged according to the same pattern. Preferably, the pattern corresponds to the pattern of the arrangement of microtitre plate wells. The invention also relates to a robot head fitted with the inventive hard metal needles. Said robot head particularly forms part of a picking and/or a spotting robot.
