Abstract:

A system for the on-line distribution and sales of electronic content over a distributed client-server network is described. A server computer maintains a database and processing engine that stores and processes data pertaining to a selection of digital content product, such as music CDs, movie DVDs, video games, computer software, and the like. A user registers for a membership on the vendor web site. Users may select from a wide range of products available through the vendor or other vendors associated with the web site. The user can search for auctions for individual titles or products. When the user wins an auction, the vendor sends the product for use during a trial period. The auction price sets the trial price for the product. Upon expiration of the trial period, the user can return the product to the vendor, or keep it and pay a price based on the trial price. The ultimate sales price is determined through a fixed price model that takes into account various factors such as trial price, wholesale price, msrp, stock levels, popularity, and so on. The trial price can be determined through the auction, or through a fixed-price model. The trial price can be wholly or partially deducted from the final sales price.

Abstract:

Embodiments of user profile tagging process for an online credit application system are described. The process stores keywords represented as tags relating to various characteristics of the user. These characteristics can include objective information regarding the user, and subjective information, such as user preferences, background, affiliations, behavior patterns, and so on. A query function allows a querying user to input query tags to determine an aggregate or mean credit score for users who have certain characteristics. In response to a user query, the system identifies all other users that match the query tags entered by the querying user. The system calculates the aggregate credit score for these other users and displays this aggregate score relative to the credit score of the querying user.

Assignee:

AC RESEARCH LABS - San Jose CA

International Classification:

F25B 29/00

US Classification:

165 481

Abstract:

Described herein is a device for cooling condenser coils of an air conditioner system, where the condenser coils are located along with a compressor within a suitable housing. Cooling is made efficient by providing a manifold located adjacent to the housing for controllably carrying water and dispensing it through a set of nozzles, which create a mist of water droplets adjacent to side walls of the housing.

International Classification:

C02F 1/48
C02F 5/00

Abstract:

An apparatus for reducing and inhibiting scale formation in water conduits is disclosed. The scale reducing apparatus has at least two stages, each stage containing one or more conduits therein surrounded by magnets. The magnets form a strong, substantially uniform magnetic field in the conduit(s) which is substantially perpendicular to the flow of water therein. Dissolved ions in the water interact with the magnetic field and may as a result be forced into contact with one another to form one or more non-dissolvable solids. The reduction in dissolved ions reduces and/or inhibits the formation of scale in the water supply lines of a structure, thus increasing the life of the conduits, appliances, and other structures where scale may form.
