Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for merging search results. In one aspect, a method combines search results responsive to a query that are obtained from a local search engine and a universal search engine such that the combined search results are ordered and presented in a way that emphasizes certain business entities in the results.

Abstract: An anhydrous, proton-conductive medium comprises a poly(amic acid)-based polyimide and at least one phosphorus compound from the group consisting of phosphorus oxides and phosphoric acids. The precursor solution for the polyimide is a mixture of a phosphorus oxide and a poly(amic acid). A suitable phosphorus oxide has the formula P4O10. A process for forming an anhydrous, proton-conductive membrane comprises mixing a phosphorus oxide in a poly(amic acid) solution to form a mixture, dispensing the mixture upon a support structure, and substantially drying the mixture. The mixture may then be cured.

Abstract: There is disclosed an electrochemical conversion system (40) for energy management which includes multi-electrochemical cells. The system 40 includes a conduit system (41), an electrical system (42), first electrochemical cell (43), a second electrochemical cell (44), a third electrochemical cell (45), a first recuperative heat exchanger (RHX) (46), and a second recuperative heat exchanger (47). The conduit system, electrical system (42), heat exchangers, and electrochemical cells are all constructed and function in the same manner as previously described. The system (40) also includes an additional, second recuperative heat exchanger (47) (RHX) to thermally isolate the third electrochemical cell from the other two. As shown, the electrochemical cells are electrically and pneumatically connected in series so that the electrical current flow and the proton flow through the electrochemical cells are balanced.

Abstract: An reversible engine (10) is disclosed having a conduit system (11), a first electrochemical cells (12), and a second electrochemical cell (13). The conduit system (11) includes a first conduit (15) extending from the first electrochemical cell (12) to the second electrochemical cell (13), and a second conduit (16) extending from the second electrochemical cell (13) to the first electrochemical cell (12). The heat engine (10) also includes a heater (18) mounted in thermal communication with the conduit system (11) adjacent the second electrochemical cell (13), a cooler (19) mounted in thermal communication with the conduit system (11) adjacent the first electrochemical cell (12), and a regenerative heat exchanger (20) thermally coupled to the first and second conduits (15) and (16) for the transfer of heat therebetween.
