Replica of the miniaturization chip prop from the 1987 movie _Innerspace_, with optional cufflink mount as featured at the end of the film. All parts are separate STL files, to allow multimaterial/color prints. For the "silicon" itself I'd recommend filing down a piece of scrap metal or something silver-coloured to the right size. The pins are included for completeness only - good luck printing them on their own ;) The holes are 0.018" (about 0.46 mm) so the body will take...

In this paper, a compact triband printed antenna with hexagonal complementary split-ring resonators (CSRRs) for 4G applications is proposed. The proposed multiband antenna is comprised of a rectangular patch antenna on the top plane, while on the ground plane, hexagonal CSRRs are etched for size miniaturization (at the lower bands) and multiband generation. Another effect of the CSRR is the shifting of the initial resonance of the patch antenna from 5.17 GHz to the higher band of 6.18 GHz. The...

A detailed description of the assembly procedure of the Floating Spacecraft Simulator (FSS) has been produced for the Naval Postgraduate Schools Spacecraft Robotics Laboratory. This procedure has been used to assemble an additional FSS, resulting in a total of three operational units. The second part of the research effort was devoted to the design of a miniaturized version of the FSS. Due to the finite size of the testbed, it was desirable to reduce the footprint of the FSS to increase the...

Ionic Liquid Ion Sources (ILIS) are devices capable of producing molecular ion beams through electrostatic stressing of room temperature molten salts, or ionic liquids. These ion beams can be applied in space propulsion, in focused ion beams for microfabrication and in reactive ion etching. To achieve ion evaporation from the ionic liquid, the liquid is supported on a micron-sized emitter tip. The emitter is subjected to an electric field to deform the liquid into a sharp meniscus, at the apex...

A large collection of white dwarf (WD) spectra from Sloan Digital Sky Survey (SDSS) data release 4 (DR4) WD catalog data allowed us to obtain a luminosity function (LF)for the hottest WDs. The LF was calculated basing on spectra of the WDs from a special class of SDSS objects called hot standards (HS), for which the WD sample completeness can be estimated. WD distances were determined from the observed and absolute SDSS g filter magnitudes derived from WD stellar atmosphere model fits to the...

The surface aging of the electrodes of miniature spark switches (A/d 50) is explored using commercial dry nitrogen as the working gas. Both brass and aluminum electrodes were investigated for aging characteristics using a constant gas flow rate of 8 cm3/sec. The gas pressure was varied from 760 torr-5200 torr. The switches were constructed as an integral part of a miniature L-C oscillator which has a ringing frequency of approximately 150 MHz. The aging process was halted at intervals ranging...

The complete system was tested with a 2.4 GHz continuous signal in an anechoic chamber. Test results showed that the compact antenna and receiver design was capable of measuring direction of arrival with 1 deg resolution over a 180 deg field of view while keeping mean error below 0.5 deg. It was also demonstrated that the...

Organophosphate (OP) poisoning can result in status epilepticus (SE), which can become pharmacoresistant if treatment is delayed. Virtually no data exist on OP-induced SE in immature animals, even though the immature brain is likely to respond differently to OPs, and the optimal therapies are also likely to differ from adults. Our aim is to identify novel drugs that block pharmacoresistant OP-induced SE, as well as pharmacoresistant LiPilo-induced SE, in immature rats, which would thus be...
