  • MULTICOMPONENT SACRIFICIAL STRUCTURE
    Publication number: 20120057216
    Abstract: A MEMS comprising a sacrificial structure, which comprises a faster etching portion and a slower etching portion, exhibits reduced damage to structural features when in forming a cavity in the MEMS by etching away the sacrificial structure. The differential etching rates mechanically decouple structural layers, thereby reducing stresses in the device during the etching process. Methods and systems are also provided.

  • Portable hand-held reusable vehicle speed limiting device
    Publication number: 20060200296
    Abstract: The Portable Hand-held Reusable Vehicle Speed Limiting Device (the Invention) is a hand-held, single person portable device intended to allow the user to set the maximum speed of a freight delivery or passenger vehicle that is propelled by an engine powered by a fuel source by means of installing a usage license to the vehicle's On-Board Engine Management Computer (OBEMC). After the license has been installed to the vehicle's OBEMC by the Invention, the vehicle will not exceed the speed set by the user of the Invention, regardless of who operates the vehicle or what input they give to the vehicle's throttle mechanism.
