The invention relates to a device for carrying out of chemical or biological reactions with a reaction vessel receiving element for receiving a microtiter plate with several reaction vessels, wherein the reaction vessel receiving element has several recesses arranged in a regular pattern to receive the respective reaction vessels, a heating device for heating the reaction vessel receiving element, and a cooling device for cooling the reaction vessel. The invention is characterized by the fact that the reaction vessel receiving element is divided into several segments. The individual segments are thermally decoupled from one another, and each segment is assigned a heating device which may be actuated independently of the others.

Methods for generating a padring layout design are described. These methods utilize automation while still allowing customization. Automation is emphasized as much as possible so that more time can be used to solve the various problems that make each padring layout design unique.

A process for forming an etch mask having a discontinuous regular pattern utilizes beads, each of which has a substantially unetchable core covered by a removable spacer coating. Beads which have a core and a spacer coating are dispensed as a hexagonally-packed monolayer onto a thermo-adhesive layer, which is on a target layer. The beads are kept in place by a bead confinement wall. Following a vibrational step which facilitates hexagonal packing of the beads, the resultant assembly is heated so that the beads adhere to the adhesive layer. Excess beads are then discarded. Spacer shell material is then removed from each of the beads, leaving core etch masks. The core-masked target layer is then plasma etched to form a column of target material directly beneath each core. The cores and any spacer material underneath the cores are removed. The resulting circular island of target material may be used as an etch mask during wet isotropic etching of an underlying layer. Such a combination of plasma etching using the bead cores as a primary mask and a wet etch using the islands formed by the plasma etch as a secondary mask may be used to form micropoint cathode emitter tips in an underlying conductive or semiconductive layer.

A system and method for treating and preventing loss of visual acuity. The system comprises a vision correcting lens, such as a contact lens, having a material with a regular pattern of orientation of polarizable molecular bonds, so as to create a birefringent effect. Off-axis light rays are refracted through the contact lens so as to focus in front of the retina, whereas on-axis light rays pass through the contact lens without refraction, such that their focal point on the fovea is unaltered. In an exemplary embodiment, a contact lens of the present invention is capable of independently altering the refractive state of the eye in relation to fovea and peripheral retina so as to simultaneously correcting visual acuity while minimizing the signal for axial growth and hence myopic progression.
