Abstract: A mixer includes a mixing chamber and a motor mechanically connected to the mixing chamber. The mixing chamber comprises a suspended elongate rigid tube section having a top end and an open bottom end, and a flexible tube section extending downwards from the open bottom end. The motor comprises a vibration motor mechanically coupled to the suspended elongate rigid tube section at the top end of the suspended elongate rigid tube section.

Abstract: The present invention relates to a system 100 for independently holding and manipulating one or more microscopic objects 158 and for targeting at least a part of the one or more microscopic objects within a trapping volume 102 with electromagnetic radiation 138. The system comprises trapping means for holding and manipulating the one or more microscopic objects and electromagnetic radiation targeting means (116). The light means comprising a light source and a spatial light modulator which serve to modify the light from the light source so as to enable specific illumination of at least a part of the one or more microscopic objects. The trapping means and the electromagnetic radiation targeting means (116) are enabled to function independently of each other, so that the trapped objects may be moved around without taking being dependent on which parts are being targeted and vice versa.

Abstract: The present invention relates to a microdevice for emitting electromagnetic radiation, the microdevice being adapted so as to be controllable by electromagnetic radiation, such as light. The microdevice comprises a first electromagnetic radiation emitting unit arranged to emit electromagnetic radiation 1728, so as to be able to irradiate electromagnetic radiation onto a structure of interest 1740. The microdevice further comprising means for enabling non-contact spatial control over the microdevice in terms of translational movement in three dimensions, and rotational movement around at least two axes. The present invention thus provides an instrument which enables controlled irradiation of light onto very well defined areas on the nano-scale of objects of interest. Furthermore, the device enables receipt of light and may thus work as an optically controlled microendoscope.

Abstract: The invention relates to encoding phase information in micro-grating-based anti-counterfeit devices such as diffractive optically variable identification devices (DOVID). The invention utilizes that alignment of grating line positions in different micro-gratings having common line spacing and orientation, can be used as a new, additional information channel in DOVIDs. By displacing grating line positions in different pixels relative to a common reference grating, relative shifts in alignment are introduced that do not affect the visual effects encoded in the DOVID. The relative shifts in line position alignment induce relative shifts in the phase of light diffracted by the DOVID, so as to introduce a spatial phase shift distribution corresponding to the distribution of position shifts over the DOVID. Such spatial phase shift distribution is not visible, and the phase encoded information is thereby invisible unless a reader based on e.g. generalized phase contrast is applied.
