Filed:

Aug 20, 2004

Appl. No.:

10/922368

Inventors:

Nicholas LeCursi - Jackson MI, US

International Classification:

H01R 43/00

US Classification:

29825, 296021, 445 35, 445 36, 445 46

Abstract:

A technique for providing a grid for a gate such as utilized in gating a stream of ions or other particles in a spectrometer instrument. The grid of wires may, for example, be a so-called Bradbury-Nielson Gate that consists of a set of two electrically isolated sets of equally spaced wires that lie substantially in the same plane and alternate in potential. The method utilized to provide is to first fabricate a frame of an insulating substrate having a hole and depositing metal film patterns such that conductive portions are formed on either side of the hole. Conductive portions on either side form a series of terminating pads on the portion of the substrate closest to the hole and a bus bar. Grid wires are then formed by stretching a section of wire with desired constant tension across the hole and bonding the ends of the wire to a respective one of the pads on one side and bus bar on the other side. The method provides a rapid, inexpensive way to fabricate such modulating devices.

International Classification:

A61F 5/01

Abstract:

An improved ankle joint device is provided. In one aspect, the device provides two stages of dorsiflexion resistance biasing a first splint member (or other attachment member that follows the angular displacement of a wearer's lower leg or foot) against dorsiflexion movement within an active angular range of dorsiflexion, corresponding to second and third rocker phases of a wearer's gait; in addition to a phase of plantarflexion resistance biasing the first splint/attachment member against plantarflexion movement within an active angular range of plantarflexion, corresponding to a first rocker phase. In another aspect, an equilibrium or neutral angle between a wearer's foot and tibia at which the device applies no biasing forces is adjustable by adjusting the angle at which a second splint/attachment member is fixed relative to a joint body. Typically, the second splint member is secured to a wearer's lower leg, and the first splint member is secured to a wearer's foot.
