An apparatus generates and/or maintains fluid flow synthesizing and maintaining an artificial tornado. The apparatus includes a generally cylindrical frame having two chambers coupled with two channels each of one half the entire length of the frame, and having reversed angular coordinates. Each chamber operates to generate and/or maintain a vortex and each channel operates to induce and/or reinforce the vortex along the length of the frame.

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.

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

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 sun shade device for use with a book includes a shade member which is pivotable with respect to a mounting apparatus. The mounting apparatus has a clip for mounting the shade to the center of a book. The shade includes a frame with a flexible member. The mounting apparatus may be folded against the shade for storage.

A small personal retail tool wirelessly connects to a wireless retail transaction server. The server sends information concerning the store's menu to the retail tool. The customer is then able to select from the menu and order using the personal retail tool. The retail server processes the order and requests payment from the retail tool. The retail tool then optionally requests a PIN number from the customer in order to access stored payment information. The order is completed and the connection is terminated. The retail server is designed to appear as a cash register to a retailer's back-end server. However, instead of going through a cashier, the retail server enables customers to place orders and make payment on their own, without first waiting in line, without rushing and without interacting with a cashier. Customers who would rather place their order with a cashier can still use the retail server solely to pay for their purchases.

By using a monolithic sheet of photodetector semiconductor and creating a series of isolated individual optical paths, the performance of a multiple channel coupler can be improved. Multiple photodetectors are fabricated on the substrate, yielding electro-optically matched devices. By using common connection of the photodetectors and common connection of the optical sources, the pin-per-channel count is minimized.

Optical feedback control in an optical emitter-detector combination can be improved by fabricating the two devices on a single substrate. The feedback radiation can then travel within a monolithic structure. This arrangement will yield greater uniformity in devices as well as provide for easier mechanical assembly.
