Assignee:

Holdit, Inc., L.L.C. - Kansas City MO

International Classification:

A47K 108

US Classification:

2483112

Abstract:

A cup-holder is provided for portable use at football games, theaters, or the like. The cup-holder is securely fastened to a top surface of an arm rest of a seat at the game. The holder includes a base having flat top and bottom surfaces. The bottom surface of the base rests flush against the seat arm rest or may fit over the arm rest. The top of the base is flat to allow the user to rest his/her arm thereon. The holder includes a cup receptacle formed from adjacent, contiguous rings which are separated with a flexible bridge. VELCRO fastening tape straps are used to secure the holder to the arm rest. Also, the top surface of the base may include indicia such as a team logo, name, team schedule, etc.

Abstract:

A fire suppression system for producing oxygen-depleted air includes a fuel cell stack formed from a plurality of fuel cells for providing power to an associated load, and a controller coupled to the plurality of fuel cells, wherein the controller is configured to regulate current output from the plurality of fuel cells to maintain a prescribed percentage level of oxygen depleted air in an exhaust stream of the plurality of fuel cells. Further, a method for maintaining an updated polarization curve for a fuel cell includes commanding step-and-hold air flow commands and associated electrical current limit commands to the fuel cell system. Upon the fuel cell reaching each successive step-and-hold steady state condition, electrical current and voltage pairs are stored and plotted to form the real-time polarization curve. Upon characterizing the fuel cell polarization curve, a maximum power line is projected at the knee of the polarization curve, above which point the system is not permitted to operate without augmentation from the battery storage device. A maximum fuel cell power capability is continually prognosticated during run-time and is used to maximize operational robustness.
