Abstract:

A method and apparatus for recognizing broadcast information, the method including the steps of receiving a set of broadcast information; converting the set of broadcast information into a frequency representation of the set of broadcast information; dividing the frequency representation into a predetermined number of frequency segments, each frequency segment representing one of the frequency bands associated with the semitones of the music scale; forming an array, wherein the number of elements in the array correspond to the predetermined number of frequency segments, and wherein each frequency segment with a value greater than a threshold value is represented by binary 1 and all other frequency segments are represented by binary 0; comparing the array to a set of reference arrays, each reference array representing a previously identified unit of information; determining, based on the comparison, whether the set of broadcast information is the same as any of the previously identified units of broadcast information.

Abstract:

An autonomous apparatus for generating real-time estimates of the time of arrival of vehicles at user selected sites. The apparatus is comprised of two separate components, a vehicle unit which is carried by each vehicle and a user unit which is carried by each user. The vehicle unit determines time and geographical position at predetermined locations and broadcast these data to the user units through a wireless communications medium. The user unit receives the time and position information and adds it to computer memory records of similar data received over a prior period of time. The combined set of recorded data is used to estimate the time that the broadcasting vehicle will arrive at a specific location, that location having been specified by the user on a previous occasion by pressing a button on the user unit when the vehicle was stopped at the selected location. The estimated arrival time is presented on a display. The system operates without any assistance or information input from humans and its user require no special knowledge or skills.
