Abstract: A web content extension system and platform is described. Web content extensions include tags as well as actionable code that supports deeper integration with web content than that supported by conventional tags, e.g., through interaction with APIs of the web content. The web content extensions are made available by developers of the extension to content creators via an extension catalog. The extension catalog thus supports a platform that unites developers of the web content extensions with content creators of web content. Further, this platform may be configured to support developer control of integration of the web content extension through use of an extension user interface that is created by the developer.

Abstract: An exemplary system for determining vehicle salvage value includes a valuation subsystem configured to communicate with one or more access devices over a data communication network. The valuation subsystem includes a bid module and a valuation module. The bid module is configured to solicit bids for a vehicle over the data communication network and to receive one or more bids for the vehicle. The valuation module is configured to set a salvage value of the vehicle based on at least one of the received bids. In some examples, the received bids include a high bid, and the valuation module is configured to set the salvage value approximately equal to the high bid. In some examples, the bid module is configured to solicit virtual bids in real time over the data communication network.

Abstract: An online auction system comprising a preliminary bidding portion and a virtual auction portion is disclosed herein. The preliminary bidding portion allows bidders to access auction items and input bids during a preestablished period of time. This preliminary bidding portion may be conducted via computers connected to the internet or via telephones connected to the public telephone network. After the preliminary bidding portion concludes, the virtual auction portion allows bidders to input bids on each item in a manner similar to a conventional live auction. During the virtual auction portion, a countdown encourages further bidding before the previous bid becomes final. After each new bid is inputted, the countdown is reinitiated. An alert system notifies bidders that a particular item of interest is about to be offered for bid as part of the virtual auction portion. The system also provides bidders means for inputting proxy bids.

Abstract: An online auction system comprising a preliminary bidding portion and a virtual auction portion is disclosed herein. The preliminary bidding portion allows bidders to access auction items and input bids during a preestablished extended period of time. After the preliminary bidding portion concludes, the virtual auction portion provides bidders the opportunity to input bids on each item consecutively and individually from the preliminary auction portion in a manner similar to a conventional live auction. During the virtual auction portion, bidders are provided with a countdown to encourage further bidding before the previous bid becomes final. After each new bid is inputted, the countdown is reinitiated. The countdown is reinitiated until no new bids are input. An alert system notifies bidders that a particular item of interest is about to be offered for bid as part of the virtual auction portion. The system also provides bidders means for inputting proxy bids.
