US Classification:

719310

Abstract:

A method in a computer system is disclosed for programmatically locating any file and building a shortcut for future reference to that file. First, a shortcut cache is created if one does not exist. Then, the shortcut cache is searched for a shortcut for the file. The shortcut contains the location and name of the file. If the shortcut name is not found, then the shortcut directory for the current user is located in the system registry, and it is searched for the shortcut name. If the shortcut name is still not found, the shortcut directory for all users is located in the system registry, and it is searched for the shortcut name. If the shortcut name is found then it is stored in the shortcut cache; and, the location and name of the file is returned to the requester.

Abstract:

Contemporary navigation systems are often tasked with routing a vehicle to a destination, but are poorly equipped to assist with finding a vacancy of a parking opportunity in which the vehicle may be parked. Static information, such as enumeration of parking garages and curbside parking meters, may be frustrating if such parking opportunities have no vacancies. The determination of vacancies with certainty may be difficult to achieve due to the characteristic volatility of parking, in which vacancies may be taken in seconds. Presented herein are navigation device configurations involving probabilistic evaluation of parking routes in a vicinity of a destination that may be generated and compared, optionally weighted by various factors, to identify a parking route with parking opportunities that collectively present a high probability of vacancy as compared with other parking routes, which may be presented to the user and/or appended to a current route of an autonomous vehicle.
