Abstract

Abstract A method for processing data received by a receiving device which outputs present location data for a movable vehicle based on the Global Positioning System and is positioned in the vehicle, including the steps of calculating an average of a predetermined number of data output from the receiving device while the vehicle stops, determining the average to be an effective data if the standard deviation of the data is within a predetermined range, and processing the averaged data as the present location data for the vehicle.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 94 words
A method for processing data received by a receiving device outputting present location data for a vehicle carrying said device based on radio waves from a plurality of satellites, said method comprising the steps of: determining if said vehicle is stopped; calculating an average of a predetermined number of data inputted into said receiving device while said vehicle is stopped; determining said average as an effective data if a standard deviation of said predetermined number of data is within a predetermined range; and calculating a present location of said vehicle from said effective data.
Claim 2
Independent Claim 94 words
A method for processing data received by a receiving device outputting present location data for a vehicle carrying said device based on radio waves from a plurality of satellites, said method comprising the steps of: determining if said vehicle is stopped; calculating an average of a predetermined number of data inputted into said receiving device while said vehicle is stopped; determining said average as an effective data if a standard deviation of said predetermined number of data is within a predetermined range; and calculating a present location of said vehicle from said effective data.
Claim 3
Dependent Claim 17 words
The method as recited in claim 1, wherein said outputted data conforms to the Global Positioning System.
Claim 4
Independent Claim 105 words
A device for determining a present location of a vehicle, comprising: a receiving device mounted in a vehicle for receiving signals from a plurality of satellites as data; means for determining if said vehicle is stopped; means for calculating an average of a predetermined number of data received by said receiving device while said vehicle is stopped; means for determining whether a standard deviation of said predetermined number of data is less then a predetermined value; and means for controlling said receiving device to calculate a present position of said vehicle based on said average if said standard deviation is less than said predetermined value.
Claim 5
Independent Claim 105 words
A device for determining a present location of a vehicle, comprising: a receiving device mounted in a vehicle for receiving signals from a plurality of satellites as data; means for determining if said vehicle is stopped; means for calculating an average of a predetermined number of data received by said receiving device while said vehicle is stopped; means for determining whether a standard deviation of said predetermined number of data is less then a predetermined value; and means for controlling said receiving device to calculate a present position of said vehicle based on said average if said standard deviation is less than said predetermined value.
Claim 6
Dependent Claim 18 words
The device as recited in claim 1, wherein said receiving device operates according to the Global Positioning System.
