Method and system for generating a metal thin film with a uniform crystalline orientation and a controlled crystalline microstructure are provided. For example, a metal layer is irradicated with a pulsed laser to completely melt the film throughout its entire thickness. The metal layer can then resolidify to form grains with a substantially uniform orientation. The resolidified metal layer can be irradiated with a sequential lateral solidification technique to modify the crystalline microstructure (e. g. , create larger grains, single-crystal regions, grain boundary controlled microstructures, etc. ) The metal layer can be irradiated by patterning a beam using a mask which includes a first region capable of attenuating the pulsed laser and a second region allowing complete irradiation of sections of the thin film being impinged by the masked laser beam. An inverse dot-patterned mask can be used, the microstructure that may have substantially the same as the geometric pattern as that of the dots of the mask.

This application describes a method and device for safely, effectively, perfusing distal to occluded arteries, based on diagnostic information from the catheter-perfusion-system based on sensors, effectors, controllers and algorithms included, with particular attention to the specific characteristics of the tissue and the fluid. Key actionable physiological values for the tissue can be calculated and derived. They include the auto-regulatory curve, with Upper and Lower limits of Auto regulation, vascular reserve, and collateral flow reserve and as auto-regulation exhaustion.

A display may have rows and columns of pixels that form an active area for displaying images. A display driver integrated circuit may provide multiplexed data signals to demultiplexer circuitry in the display. The demultiplexer circuitry may demultiplex the data signals and provide the demultiplexed data signals to the pixels on data lines. Gate lines may control the loading of the data signals into the pixels. The display may have a length dimension and a width dimension that is shorter than the length dimension. The data lines may extend parallel to the width dimension and the gate lines may extend parallel to the length dimension such that there are more data lines than gate lines in the display. A notch that is free of pixels may extend into the active area. Data lines extending parallel to the width dimension of the display may be routed around the notch.

The present application provides systems that include a controller, and an insertion device with at least one temperatures sensor thereon and a pump coupled to the controller. The insertion device provides temperature measurement(s) at/of a subject's organ to the controller and the controller varies an infusate flow rate to induce temperature changes in at least a portion of the subject's organ and stores the temperature measurements during perfusion induced temperature changes on a memory device. The controller may estimate at least one hemodynamic characteristic of at least a portion of the subject's organ based on the temperature measurements obtained during perfusion induced temperature changes.

A process for fabrication of a power semiconductor device is disclosed in which a single photomask is used to define each of p-conductivity well regions and n-conductivity type source regions. In the process a single photomask is deposited on a layer of polysilicon on a wafer, the polysilicon layer is removed from first regions of the power semiconductor device where the p-conductivity well regions and the n-conductivity type source regions are to be formed, and both p-conductivity type and n-conductivity type dopants are introduced into the wafer through the first regions.
