Patent
Charge-pump voltage converter
TL;DR: In this paper, a charge-pump voltage converter for converting a low voltage provided by a low-voltage source to a higher voltage is described, where charge is inductively generated on a transfer rotor electrode during its transit past an inductor stator electrode and subsequently transferred by the rotating rotor to a collector stator for storage or use.
Journal ArticleDOI
Fabrication of Mems Devices by Powder-Filling into DXRL-Formed Molds
TL;DR: In this paper, a variety of processes for fabricating components for micro devices based on deep x-ray lithography (DXRL) were developed for Nd 2Fe14B and Ni-Zn ferrite magnetic materials.
Proceedings ArticleDOI
Fabrication of Micro-Optical Systems with Deep X-Ray Lithography
TL;DR: In this article, prealigned, prealigned microlens systems have been fabricated in PMMA using Deep X-ray Lithography (DXRL) using cross cylindrical lenses with ≈0.3mm apertures.
Patent
Spin-stabilized magnetic levitation without vertical axis of rotation
TL;DR: In this article, the symmetry properties of a magnetic levitation arrangement are exploited to produce spin-stabilized magnetic levitations without aligning the rotational axis of the rotor with the direction of the force of gravity.
