Design and fabrication of a digitally reconfigurable surface
The digitally reconfigurable surface is a pin based mechanism for creating physical threedimensional contoured surfaces from a computer aided design (CAD) input. When the digital design is properly downloaded into the device, a pin array is collectively actuated to the desired geometry. A rubber …

Tactile perception of spatially distributed vibratory stimuli on the fingerpad
Using a pin-array type tactile display as a stimulator of the finger pad, a psychophysical study was conducted on the vibrotactile perception. The passive touch with vibratory stimuli in the low frequency could be an alternative of the active touch for the presented stimuli: polygons, round shapes …

Thermal hydraulic analysis of hydride fuels in BWR's
… flow velocity and pressure drop constrain only pin array geometry and diameter. It is shown that applicable uranium oxide and hydride fuel limits are both met within the constraints imposed by these three limits which were applied.

Design of a low enrichment, enhanced fast flux core for the Massachusetts Institute of Technology Research Reactor
… fissile material, arranged in a tight hexagonal pin array, can be uranium enriched in either 235U or 233U, to the limit allowable for non-proliferation. Insertion of the Fast Flux Trap in the proposed low enriched uranium core operated at a 10 MW power level, can provide a 252%-271% higher fast …

Experimental Investigation of Heat Transfer to Tightly Packed Cylinder Arrays
… system. A proposed configuration is an array of batteries directly cooled with a dielectric coolant. The knowledge of heat transfer characteristics of battery cooling is becoming an ever pressing issue due to the need to optimize volume and mass in a safe manner. Tighter spacings between …

Practical pin tooling
… few possible applications. Resembling the common pin art toy, a discrete element pin bed has often been proposed as a design for a reconfigurable mold. Conventional actuation strategies are often cumbersome and expensive, due to the quadratic increase in number of pin elements with increasing …

Algorithmic studies on PCB routing
… the package size keeps shrinking while the pin count of a package keeps increasing. A modern IC package can have a pin count of thousands. As a result, a complex printed circuit board (PCB) can host more than ten thousand signal nets. Such a huge pin count and net count make manual design of …

New methods for electronic design automation problems
… a modern package can contain thousands of pins. On the other hand, the size of a package is still kept to a minimum. This makes the footprint of such a package on a PCB a very dense pin grid, such that staggered pin arrays have been introduced for modern designs with high pin density. …
