Abstract: The present invention relates to a method for determining the identity of a microfluidic device and a home position by means of a set of home position marks on the microfluidic device, which is of the type used in a microfluidic system. Said method comprises following phases: a microfluidic device scanning phase, wherein a microfluidic device is scanned for mark identifiers; a microfluidic device identifying phase, wherein at least one a characteristic feature of the set of home marks is/are determined and used for identifying the identity of the microfluidic device; a home position determining phase, wherein the home position is determined by the use of at least a subset of the home position marks identified during said previous phases. The present invention relates to a set of home marks, a microfluidic device carrying such a set of home marks, a microfluidic system, a computer program product and a computer program on a computer usable medium.

Abstract: A microfluidic device having a plurality of microchannel structures and a memory. The memory may be writeable with restriction for unauthorized access. Yet further, the memory can be information about positions of non-redundant or redundant microchannel, information relating to positions for interfacing the microchannel structures with the macroworld, or supplemental information relating to process protocols that are allowed for the microchannel structures of the device.

Abstract: A pen having a holder (10) and a mechanism (11) arranged in the pen, comprises a substantially hemispherical writing end and has such a mass distribution that its centre of gravity is located between the crest of the writing end and the meridian plane of the substantially hemispherical writing end, such that the pen, when put e.g. on a table and having its nib (12) retracted, will automatically rise so as to stand substantially on the crest of the writing end when in its resting position.
