Abstract: Solar collection systems are provided herein that includes a mobile, self-tracking receiver support member which is suspended from a support beam spanning the two sides of an immobile solar trough concentrator. The self-tracking receiver support member has photovoltaic cells of equal power affixed to two or more downward facing surfaces of the support member. These photovoltaic cells face downward into the solar parabolic trough concentrator and respond to the concentrated light of the path of the points of focus being reflected upwards from a parabolic concentrator. The solar cells are wired to a DC electric motor so that the motor rotationally responds to the disparity in the power output of the solar cells. As the path of the points of focus of the solar concentrator moves to one side or the other of the center of the self-tracking support member, the motor automatically moves the support member, along with and the receiver it is carrying, into the parabolic concentrator's path of the points of focus.

Abstract: A support rack for storing, organizing and managing tack is disclosed having a backbone, at least one support leg attached to the backbone for securing the support rack to a fence and at least one hook attached to the backbone for allowing tack to be placed on the hook and for receiving, supporting and organizing tack. The support rack may be placed over fence rails of a fence such as is typically found near show arenas or corrals or, in one embodiment, may be placed directly on a flat surface. As a result, the support rack for tack, particularly equine tack, is a unitized convenient means to organize, store and transport tack in an efficient manner.

Abstract: A computer-implemented financial management system provides the trading of securities via a network using virtual currency. A server computer receives buy and sell orders for derivative financial instruments from a plurality of client computers. The server computer attempts to match the buy and sell orders and then generates a market price through the use of a virtual specialist program executed by the server computer. The virtual specialist program responds to an imbalance in the matching of the buy and sell orders. The virtual currency accumulated by HSX account holders as a result of successful trading may be converted to another currency, credited toward the cost of merchandise provided through a vendor's web site, etc.

Abstract: Methods for providing gaming advice are provided. For example, regarding a blackjack game, one or more first player cards are identified for a first player and one or more second player cards are identified for a second player. The first and second player cards are displayed to the first player. A probability associated with a first one of the plurality of playing options is determined based at least on a set of predetermined statistical blackjack data, the one or more first player cards, and the one or more second player cards. It is then determined, based at least on the determined probability associated with the first playing option, whether to display a first indication corresponding with first advice regarding the first playing option, a second indication corresponding with second advice regarding the first playing option, or a third indication corresponding with third advice regarding the first playing option.

Abstract: The present invention relates to systems and methods for implementing an automated auction process that is held at a designated time on the Internet, and that ends after bidding has been completed. In accordance with these systems and methods, a server connected to a plurality of workstations may establish several auctions that allow for efficient trading of multiple goods, while simulating the live and dynamic setting of traditional auctions.
