Automated Hand Dispenser

An automated nanoliter dispenser for staining individual biopsies in tissue microarrays.

In the field of molecular analysis of cancer, there exists a need for a clinical device that can automate protocols for immunohistochemical and in situ hybridization diagnostic staining on tissue microarrays. The tissue microarray antibody spotter (TMAS) has been developed to provide fundamental improvements over current histological staining techniques by enabling precision application of reag...

The General Dispenser

Automated Digital Conversion of Hand-Drawn Plots

An algorithm has been developed using Matlab that takes an image of a sketch of one or more functions, plotted on the xand yaxes, and converts it into an electronic plot, along with the set of equations and parameters that recreate the same plot. This is accomplished by extraction of the plot data, followed by data grouping based on three different heuristic methods (colour, slope and process o...

Traveling with a Pez Dispenser

MultiProtocol Label Switching (MPLS) [6, 11] is routing model proposed by the IETF for the Internet, and is becoming widely popular. In this paper, we initiate a theoretical study of the routing model, and give routing algorithms and lower bounds in a variety of situations. We first study the routing problems on the line. We then build up our results from paths through trees to more general gra...

Bubble dispenser in microfluidic devices.

This Brief Report presents experimental and computational results on bubble formation in microfluidic devices. Bubbles are generated at the right-angle intersection of four identical square microchannels. When the pressure gradient generated by the liquid flow dominates the pressure gradient generated by gas flow, the length of the produced confined bubbles follows a law based on the channel si...
