Abstract: The present invention provides an underwater breathing device. The device includes a canister having a pump installed therein, wherein air outside of the canister communicates with the interior of the canister via the pump; a mouthpiece; and an elongate tube interconnecting the interior of the canister and the mouthpiece. Methods of making and using the device are also disclosed.

Abstract: A method and apparatus for configuring and entering bids in an auction is disclosed. The method includes displaying a bid adjustment mechanism configuration interfaced to a bidder. Thereafter, a bid adjustment value for the bid adjustment mechanism is set using the configuration interface. Following the setting step, upon actuation of the bid adjustment mechanism, a bid is adjusted by the bid adjustment value previously set using the configuration interface.

Abstract: An auction methodology wherein individual demands are bid in lots and an aggregation of several lots is then run as an individual lot to determine if the buyer can attract a lower price offering from bidders by selecting to award the total volume of all of the individual lots to one bidder. A bidder-specific transformation factor for the aggregate lot is computed by combining selected transformed values (one for each lot) that take into account that bidder's price offerings for individual lots and the buyer-specified transformation factors for that bidder. Each bidder is then invited to bid a discount percentage for the aggregate lot. This discount percentage is then used along with the bidder-specific transformation factor to generate that bidder's transformed value for the aggregate lot. The bidder with the lowest transformed value for the aggregate lot may be selected as the winning bidder.

Abstract: An auction is conducted by obtaining, from a buyer, information associated with a product to be purchased using an auction, where the buyer purchases the product from a winning bidder. The obtained information associated with the product is made available to at least a first bidder and a second bidder. A first bid that includes a first price and a first non-price information is received from the first bidder. A second bid that includes a second price and a second non-price information is received, from the second bidder. Non-price information is associated with (1) a description of a particular product a given bidder will provide in the event the given bidder wins the auction and/or (2) delivery of a product by the given bidder in the event the given bidder wins the auction. A first comparison value is generated based at least in part on the first price and the first non-price information. A second comparison value is generated based at least in part on the second price and the second non-price information.

Abstract: A method and system for conducting electronic auctions is described. A dynamic lot closing extension feature avoids collisions in closing times of multiple lots by dynamically extending the closing time of a subsequent lot if a preceding lot's closing time is extended to be too close to the subsequent lot's then-currently scheduled closing time. Scheduled closing times can be extended with a flexible overtime feature, in which the properties of the event triggering the extension and the duration of the overtime period(s) can be tailored to a particular auction, particular lots of products within an auction, and to the particular time within an auction process. The bidding status of a lot can be set to a “pending” status after the nominal closing time for submission of bids to allow bidders to alert the auction coordinator of technical problems in submission of bids. This allows the possibility for a lot to be return to open status for further bidding by all bidders.

Abstract: A permanent magnet structure provides high fields (e.g., .about. 4500 Gauss) with excellent uniformity (e.g., .+-. 3 Gauss) over a moderately large volume of the gap (e.g., approximately 20 percent of the gap diameter and gap width). This is accomplished by grinding away a portion of the permanent magnet material at the center of each face of the gap to form a depression, deepest at the center of the face. The magnet may include means for varying the gap width and a modulating coil for low frequency minor variation of the magnetic field. The magnet structure is used in conjunction with a 12 GHz self-excited spin resonance cavity to form a compact, portable electron spin resonance spectrometer.
