  • Publication number: 20240361127
    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.

  • Patent number: 6862733
    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.

  • Patent number: 6754618
    Abstract: A communication system is disclosed in one embodiment of the present invention to include an encoder circuit responsive to an audio signal for performing compression on the audio signal and adaptive to generate an audio output signal based upon the compressed audio signal, the encoder circuit for sampling the audio signal to generated sampled signals, each sampled signals having a real and an imaginary component associated therewith, each sampled signal having an energy and a phase defined within a current block and each sampled signal being transformed to have a real and an imaginary component, a previous block preceding the current block and a block preceding the previous block, the encoder circuit for calculating the phase of the samples of the current block using the real and the imaginary components of the samples of the previous block and the block preceding the previous block, wherein calculations for determining the unpredictability measure is reduced by avoiding trigonometric calculations of the samp
