A hierarchical deep-learning object detection framework provides a method for identifying objects of interest in high-resolution, high pixel count images, wherein the objects of interest comprise a relatively a small pixel count when compared to the overall image. The method uses first deep-learning model to analyze the high pixel count images, in whole or as a patchwork, at a lower resolution to identify objects, and a second deep-learning model to analyze the objects at a higher resolution to classify the objects.

Method for object detection using hierarchical deep learning

A method of replicating master molds used in the fabrication of microsystems having micron to millimeter sized features. Master molds are replicated using a polymer sheet, which is heated and melted onto an elastomeric mold fabricated from the master mold. The copy molds accurately replicate the geometries of the master mold, such as high aspect ratio features, microposts, and channels with slender sidewalls. The polymer sheet encases the elastomeric mold without the application of an external force, permitting copying without deformation of the features.

A flexible and stretchable integrated electronic device includes a substrate having a stiffness gradient, wherein a rigid electronic device is embedded within the substrate. The stiffness gradient within the substrate prevents delamination at the interface between the substrate and the embedded device. The stiffness gradient is accomplished by providing at least two distinct zones in the substrate with uniform stiffness, with each zone decreasing in stiffness as in a distance from the embedded device increases, or the gradient is accomplished by having a zone with a varying stiffness.

A method and device for fabricating vascular networks in for tissue engineering. The vascular network is embedded in a porous scaffold and is created from a sacrificial wax template, according to one embodiment. A extrusion-based three dimensional printer is used to create the template, wherein the printer utilizes an extruder incorporating a mixer to maintain the consistency of the extrudate.

The present invention relates generally to a method that is used to create three-dimensional synthetic vascular networks. Micromachining and molding techniques are used to create a template in a shape that mimics a biological network. Cellular material can be seeded around the template or a space created by the template and grown into an engineered tissue-construct.

A fluid-pressure regulator for regulating the pressure of a fluid. The regulator includes a variable-resistance fluid element and a variable-volume fluid element located downstream of the variable-resistance element. Pressure in the fluid at the outlet of the regulator is controlled by substantially simultaneously changing the resistance of the variable-resistance element and the volume of the variable-volume element. In one example, a decrease in pressure is effected at the outlet by simultaneously increasing the resistance of the variable-resistance element and increasing the volume of the variable-volume element. Some embodiments of the regulator are particularly useful to effect long-term and high-speed pressure changes in high-resistance fluidic channel networks.
