Abstract: Various embodiments of a dimmable power supply are disclosed herein. For example, some embodiments provide a dimmable power supply including an input current path, a switch in the input current path, an energy storage device connected to the input current path, a load output connected to the energy storage device, and a timer-based variable pulse generator connected to a control input of the switch. The timer-based variable pulse generator is adapted to generate a stream of pulses having a variable on-time and off-time. The dimmable power supply is adapted to vary the on-time and off-time to control a current at the load output.

Abstract: A device and methods for performing biological or chemical analysis is provided. The device includes an array of three-dimensional microcolumns projecting away from a support plate. Each microcolumn has a relatively planar, first surface remote from the support plate. An array of multiple, different biological materials may be attached to the first surface. The device, when used in combination with existent micro-titer well plates, can improve efficiency of binding assays using microarrays for high-throughput capacity.

Abstract: Self-aligned aperture masks are produced using a positive-acting photoresist (18) which is developed with a liquid developer. The apertures (30) of the mask have lower levels of inter-aperture variability than masks produced using mechanical transfer of toner particles (FIGS. 4-5 and 7-8), both for the apertures of a given mask and between masks.

Abstract: A pin plate used to print a high density array printing of materials such as biological inks and a method for manufacturing the pin plate are described herein. The pin plate can be manufactured by coating a top surface of a silica wafer with a substantially thick layer of photoresist material. Next, a photolithography process is used to remove selected areas of the photoresist material from the silica wafer. Thereafter, a reactive ion etching process is used to form the pins in the silica wafer by etching away a predetermined amount of the top surface from the silica wafer that is not covered by the photoresist material. Afterwards, the remaining photoresist material is removed from the silica wafer which now resembles the pin plate.
