Abstract: In some implementations, a computing device can proactively determine a destination and request traffic information for routes from a starting location to the destination. In some implementations, a computing device can identify some routes between a starting location and a destination as non-recommended routes and recommend other routes. In some implementations, a computing device can rank routes between a starting location and a destination based on automatically-determined user interest. In some implementations, a computing device can determine a user is familiar with a route and adjust the information presented to the user about the route accordingly.

Abstract: Disclosed are trisubstituted benzene derivatives of the formula ##STR1## wherein B is selected from the group consisting of --NHCOC(CH.sub.3).sub.3, 1,3-oxazolinyl and --CONHR, wherein R is methyl, phenyl, or t-butyl; Y is selected from the group consisting of CO.sub.2 H, CHO, CO.sub.2 R' and COR', wherein R' is a lower alkyl having from 1 to 4 carbon atoms; and A is H or tetrahydropyran. Said compounds are valuable intermediates in the preparation of certain anti-allergic chromone or thiochromone-5-oxamic acid derivatives.

Abstract: 1-(4-Cyano-phenoxy)-2-hydroxy-3-[2-(5-1H-tetrazolyl)-chromon-5-yloxy]-propa ne and its pharmacologically acceptable salts, are useful in the treatment of allergies, allergic asthma and inflammation.

Abstract: Certain substituted cycloalkenochromones and pharmacologically acceptable salts thereof are disclosed as being useful in the treatment of allergies. The compounds have the structure: ##STR1## X is --O--, --S--, or --SO.sub.2. Y is from 1 to 4. R.sub.1 is H or alkyl, and R.sub.2 is H, alkyl, aryl, carboxyl, alkoxy, aralkoxy, or alkoxycarbonyl. When R.sub.1 is alkyl, R.sub.2 is hydrogen, alkyl or aryl. At least one of R.sub.2 and R.sub.3 is alkoxycarbonyl, carboxyl or tetrazolyl. R.sub.3 is carboxyl, alkylthio, alkylsulfonyl, alkylsulfinyl, alkoxycarbonyl, or tetrazolyl.
