First Claim
1. A method of summarizing data, said method comprising steps ofcapturing data pertaining to reports of at least one operating condition of at least one system during a period of operation, said at least one operating condition having a dynamic range and said reports being represented in respective rows of data,assigning a value to each possible reportable value of at least one operating parameter of said at least one operating condition of said at least one system, whereby said at least one operating parameter are variable operating parameters of a vehicle and the value assigned is a discrete value selected from a list of all possible values,counting a number of occurrences of each said value in the captured data to produce counts of respective values for said at least one operating parameter of said at least one operating condition,forming a histogram of said counts, andrepresenting said histogram in fewer rows of data than said rows of data of said reports.

Abstract
Large amounts of data resulting from periodic sampling and capture of data corresponding to variable operational parameters of one or more systems, such as a plurality of vehicles, and stored in a large number of rows of data corresponding to the number of captured samples are summarized in an analytically meaningful way by simply counting the instances of particular values of the operational parameters of interest in the form of a histogram and stored as a single row of data. The reduction in number of rows of data allows acceleration of processing of later queries by a factor of one thousand (assuming an average trip length of ten minutes) or more.

14. Apparatus for summarizing data including
at least one sensor to capture values of at least one operating parameter of at least one operating condition of a system as respective rows of data, said at least one operating condition having a dynamic range and whereby said at least one operating parameter of said system are variable operating parameters of a vehicle; -
a memory to store said values of at least one operating parameter over a period of operation of said system; a processor for evaluating said values stored in said memory to determine if the period of operation of said system is valid or exceptional and, if said values for said period of operation are determined to be valid, assigning a discrete value selected from a list of all possible values to each captured value and counting a number of occurrences of each said discrete value assigned to each said captured value to produce counts of respective values for said at least one operating parameter during said period of operation; and storage to store results of said counting by said processor as fewer rows of data than said respective rows of data. - View Dependent Claims (15, 16, 17, 18, 19)

20. A method of summarizing data, said method comprising steps of
capturing data pertaining to reports of at least one operating condition of at least one system during a period of operation, said at least one operating condition having a dynamic range and said reports being represented in respective rows of data, assigning a value to each possible reportable value of at least one operating parameter of said at least one operating condition of said at least one system, whereby said at least one operating parameter are variable operating parameters of a vehicle and the value assigned is a discrete value selected from a list of all possible values, configuring a data processor to count a number of occurrences of each said value in said captured data to produce counts of respective values for said at least one operating parameter of said at least one operating condition, and configuring a data processor to form a histogram of said counts, and to represent said histogram in fewer rows of data than said rows of data of said reports.
