Method and apparatus for processing a substrate with an energetic particle beam. Features on the substrate are oriented relative to the energetic particle beam and the substrate is scanned through the energetic particle beam. The substrate is periodically indexed about its azimuthal axis of symmetry, while shielded from exposure to the energetic particle beam, to reorient the features relative to the major dimension of the beam.

A wild bird feeder comprising a container and a base. A cable extends through the container and base and is provided with a hanging loop at one end and a bottom cover at the other end for retaining the components of the bird feeder between them and suspending the bird feeder in a hanging position when hung from a tree or otherwise. The container comprises and is formed by a cover, a dome, a collar, and a hopper. In use, the cover can be detached from the dome to expose a first opening and/or the cover and dome can be detached from the hopper to expose a second opening to pour bird seed into the bird feeder, the star shaped opening of the cover frictionally engaging the cable to retain the cover and/or the cover and dome in their respective open positions during re-filling of the bird feeder.

Computer systems, methods, and exchanges for generating and trading novel investment products (“Vxlshares”) are described. In some embodiments, the computer system comprises a computer-readable storage medium including data encoding a value for the Vxlshare based on an underlying. The computer-readable storage medium further includes data encoding an expiration date for the Vxlshare. The computer-readable storage medium of the computer further includes data encoding a price for trading the Vxlshare, the price for trading being a function of the underlying. The computer-readable storage medium also includes data encoding an alpha-numeric symbol for the Vxlshare. The computer is configured to enable execution of trades of the Vxlshare on a platform, such as options platform, an OTC platform, or a platform especially designed for the trading of Vxlshares, on which shares of fully collateralized instruments are traded.

Isolation and interconnection of a telephone network of tip and ring lines and the analog ports of a modem are achieved with a transhybrid that incorporates optically-coupled isolation stages. Optical isolators directly connect to the tip and ring lines to provide optimal isolation and unidirectional transfer of signals.

A template for teaching a golfer a proper swing includes a false target disposed on a first portion of the template for positioning a golfer at a start of teaching a proper swing. A real target for being struck by the golfer during teaching is not disposed on the first portion of the template. A first marking is disposed on the first portion of the template, the first marking being disposed behind the false target and indicating a position for placing the real target off of the first portion of the template.
摘要:
A wild bird feeder comprising a container and a base. A cable extends through the container and the base and is provided with a hanging loop at one end and a bottom cover at the other end for retaining the components of the bird feeder between them and suspending the bird feeder in a hanging position when hung from a tree or otherwise. The container comprises and is formed by a cover, a dome, a collar, and a hopper. The cover is provided with a star shaped opening that frictionally engages with the hanging cable for enabling the separation of the cover from the dome to fill the bird feeder when the bird feeder is in the hanging position. The collar comprises a plurality of divider walls for creating a plurality of sections to direct the bird feed when filling the bird feeder. The hopper comprises a vertical column having a plurality of ports. The base comprises a tray having a conical shaped cone that is centrally located within the vertical column for directing the bird seed out the plurality of ports. The hopper is releaseably attached or fastened to the base for enabling cleaning of the bird feeder in either the hanging or non-hanging position. A perch ring is provided on the base to support the birds when feeding.
