Abstract

Methods and systems are provided for correlating mobile platform data with secondary device data. In an exemplary embodiment, mobile platform data and secondary device data are obtained. The mobile platform data pertains to a mobile platform. The secondary device data originates from a secondary device that is movably disposed within the mobile platform at certain times. The obtaining of the secondary device data is independent from the obtaining of the mobile platform data. The mobile platform data is correlated with the secondary device data, via a processor.

First claim

What is claimed is:

1. A method comprising:
obtaining mobile platform data, the mobile platform data pertaining to a mobile platform;
obtaining secondary device data, the secondary device data originating from a secondary device that is movably disposed within the mobile platform at certain times, wherein the obtaining of the secondary device data is independent from the obtaining of the mobile platform data; and
correlating the mobile platform data with the secondary device data, via a processor of a remote server that is remote from both the mobile platform and the secondary device, including by:
generating, via the processor, a mobile platform event space for the mobile platform data;
generating, via the processor, a secondary device event space for the secondary device data;
performing, via the processor, a cross-correlation between the mobile platform event space and the secondary device event space; and
applying, via the processor, a preliminary limitation on a search space for the mobile platform event space and the secondary device event space prior to performing the cross-correlation, including by performing pre-filtering to both the mobile platform data and the secondary device data in order to reduce the search space for correlating the mobile platform data with the secondary device data that restricts the comparisons to respective data sets of mobile platform trip data sets with respective device trip data set that could be feasible or compatible with one another, the pre-filtering incorporating localized geo-hashed spaces in addition to time-hashing for start and end times.

2. The method of claim 1 , wherein the mobile platform data originates from one or more sensors that are built into the mobile platform.

3. The method of claim 1 , wherein the mobile platform data originates from one or more additional devices that are configured to detect mobile platform events, collect sensor data during operation of the mobile platform, or both.

4. The method of claim 1 , wherein the correlating of the mobile platform data with the secondary device data is performed via the processor without any prior association between the mobile platform and the secondary device.

5. The method of claim 1 , wherein the step of performing the cross-correlation comprises:
performing, via the processor, a DSP convolution with respect to the secondary device event space, generating a filtered secondary device event space; and
performing, via the processor, a DSP cross-correlation between the mobile platform event space and the filtered secondary device event space.

6. The method of claim 1 , further comprising:
assigning, via the processor, a probabilistic likelihood as to whether the secondary device was disposed within the mobile platform based on the correlating of the mobile platform data with the secondary device data.

7. A system comprising:
a non-transitory computer readable storage medium that is configured to store:
mobile platform data, the mobile platform data pertaining to a mobile platform; and
secondary device data, the secondary device data originating from a secondary device that is movably disposed within the mobile platform at certain times, wherein the mobile platform data was obtained separately from the secondary device data; and

a processor that is coupled to the non-transitory computer readable storage medium and that is configured to at least facilitate correlating the mobile platform data with the secondary device data, including by:
generating a mobile platform event space for the mobile platform data;
generating a secondary device event space for the secondary device data;
performing a cross-correlation between the mobile platform event space and the secondary device event space; and
applying a preliminary limitation on a search space for the mobile platform event space and the secondary device event space prior to performing the cross-correlation, including by performing pre-filtering to both the mobile platform data and the secondary device data in order to reduce the search space for correlating the mobile platform data with the secondary device data that restricts the comparisons to respective data sets of mobile platform trip data sets with respective device trip data set that could be feasible or compatible with one another, the pre-filtering incorporating localized geo-hashed spaces in addition to time-hashing for start and end times.

8. The system of claim 7 , wherein the mobile platform data originates from one or more sensors that are built into the mobile platform.

9. The system of claim 7 , wherein the mobile platform data originates from one or more additional devices that are configured to detect mobile platform events, collect sensor data during operation of the mobile platform, or both.

10. The system of claim 7 , wherein the processor is configured to at least facilitate correlating the mobile platform data with the secondary device data without any prior association between the mobile platform and the secondary device.

11. The system of claim 7 , wherein the processor is further configured to at least facilitate:
performing a DSP convolution with respect to the secondary device event space, generating a filtered secondary device event space; and
performing a DSP cross-correlation between the mobile platform event space and the filtered secondary device event space.

12. The system of claim 7 , wherein the processor is further configured to at least facilitate assigning a probabilistic assignment matrix between the mobile platform data and the secondary device data based on the correlating of the mobile platform data with the secondary device data.

13. A system comprising:
a transceiver configured to at least facilitate:
obtaining mobile platform data pertaining to a mobile platform; and
obtaining secondary device data from a secondary device that is remote from the system and that is movably disposed within the mobile platform at certain times, wherein the obtaining of the secondary device data is independent from the obtaining of the mobile platform data;

a non-transitory computer readable storage medium that is configured to store a program along with the mobile platform data and the secondary device data; and
a processor that is coupled to both the transceiver and the non-transitory computer readable storage medium, and that is configured to execute the program and, in accordance with the program, to at least facilitate correlating the mobile platform data with the secondary device data, including by:
generating a mobile platform event space for the mobile platform data;
generating a secondary device event space for the secondary device data;
performing a cross-correlation between the mobile platform event space and the secondary device event space; and
applying a preliminary limitation on a search space for the mobile platform event space and the secondary device event space prior to performing the cross-correlation, including by performing pre-filtering to both the mobile platform data and the secondary device data in order to reduce the search space for correlating the mobile platform data with the secondary device data that restricts the comparisons to respective data sets of mobile platform trip data sets with respective device trip data set that could be feasible or compatible with one another, the pre-filtering incorporating localized geo-hashed spaces in addition to time-hashing for start and end times.

14. The system of claim 13 , wherein the mobile platform data originates from one or more sensors that are built into the mobile platform.
