Abstract: This invention can be embodied in smart clothing for recognizing full-body human motion based on the pressure levels of a flowable substance within two different sets of flexible tubes or channels which are integrated into clothing (or a wearable accessory) and which span the same body joint. This technology can be used to create a wearable, mobile, reasonably-priced, and relatively-unobtrusive full-body motion-capture system which can be used in diverse environments. Compared to camera-based motion capture systems, this invention can be mobile and does not suffer from optical occlusion.

Abstract: A facility for rendering a dynamic electronic document is described. The dynamic electronic document has both a current and a future edition. The current edition incorporates a current version of a content item, while the future edition incorporates a future version of the content item. The facility receives a request to return the dynamic electronic document. In response to the request, the facility retrieves a template for the electronic document that contains a single identifier that identifies a group of content item versions containing both the current version of the content item and the future version of the content item. The facility uses the single identifier contained in the template, together with an indication of whether the current edition of the dynamic electronic document or the future version is being requested by the received request, to incorporate the appropriate version of the content item in the rendered dynamic electronic document.

Abstract: A method and system for authenticating users while conducting an auction via a computer system. The system can automatically authenticate users who have previously registered with the auction system and who have enabled automatic authentication. When a user is registered, the system may store authentication information in a cookie on the user's computer. When the user decides to perform a transaction (e.g., list item auction or place a bid for an item) that requires authentication, the system retrieves the stored authentication information. If automatic authentication is enabled, then the system allows the transaction to proceed without manual authentication. If, however, automatic authentication is not enabled or the system does not recognize the stored authentication information, then the system requests manual authentication. The use of automatic authentication allows a user to enter information relating to a transaction without manually entering any identification information.

Abstract: Display space on web page may be allocated by bids. In one embodiment, the display space system receives bids indicating a bid amount and an advertisement. When providing a web page with the display space, the display space system selects a bid. The display space system adds the advertisement of the selected bid to the web page. The bid may specify web pages on which the advertisement may be placed, the users to whom the advertisement may be presented, and time when the advertisement may be placed. The bid amount may be in an established currency or in advertising points. Activities for which advertising points may be awarded may include listing an auction, auction bidding, or purchasing of an item. When a user advertisement is placed, the display space system reduces user advertising points. The display space system may also place bids for display space on behalf of the user.

Abstract: A method and system for generating transaction price data relating to electronic commerce. In one embodiment, the system classifies items based on an item classification hierarchy. Each item classification in the hierarchy may have associated item-specific attributes. When a commercial transaction relating to an item is conducted, the item is identified based on its item classification and values for the associated item-specific attributes. The system records information relating to commercial transactions for items that have been so identified and uses those records to generate transaction price data. When generating transaction price data, the system may allow the user to specify an item classification along with values of its attributes. The system identifies records of commercial transactions relating to items with that item classification and with matching attribute values and bases the transaction price data on those identified records.

Abstract: A facility for specifying and previewing changes to a web site is described. Sets of changes to a web site are scheduled for release at a specified time. While the changes are being specified using a tool/interface, methods for showing the change as it will appear on the live web site are implemented. Inconsistencies between specified changes and changes in future releases may be identified as the changes are specified. Web page preview functionality is provided to allow any release to be viewed before publication to a live web site. The preview further allows inconsistencies between selected changes and changes in other future releases to be identified.

For example, the system may evaluate commercial transactions relating to a fixed-price sales or auctions to a suggest the fair market value of the item. When generating transaction price data, the system may allow the user to specify an item classification along with values of its attributes.

Abstract: A method and system for allocating display space on web page. In one embodiment, the display space system receives multiple bids each indicating a bid amount and an advertisement. When a request is received to provide a web page that includes the display space, the display space system selects a bid based in part on the bid amount. The display space system then adds the advertisement of the selected bid to the web page. The bid may also include various criteria that specify the web pages on which the advertisement may be placed, the users to whom the advertisement may be presented, and the time when the advertisement may be placed. The bid amount may be a based on an established currency or based on advertising points. The display space system may award advertising points for various activities that users perform.
