Devices, methods, and programs for identifying radio communication devices
First Claim
1. An in-vehicle device configured for installation in a subject vehicle, comprising:
- a communication unit that performs a first search and second search to identify radio communication devices in a vicinity of the in-vehicle device;
a storage unit that stores addresses of the radio communication devices identified by the first search and the second search; and
controller that;
determines whether the subject vehicle is driving;
compares the addresses of the radio communication devices identified by the second search with the addresses of the radio communication devices identified by the first search; and
determines that a particular radio communication device is inside the subject vehicle if that particular radio communication device'"'"'s address is identified by both the first search and the second search;
wherein the controller causes the communication unit to perform the first search and the second search when it is determined that the subject vehicle is driving.

Abstract
Devices, methods, and programs for identifying radio communication devices in a subject vehicle perform a first search and second search for radio communication devices in a vicinity of an in-vehicle device and store addresses of the radio communication devices identified by the first search and the second search. The devices, methods, and programs compare the addresses of the radio communication devices searched by the second search with the addresses of the radio communication devices searched by the first search, and determine that a particular radio communication device is inside the subject vehicle if that particular radio communication device'"'"'s address is identified by both the first search and the second search.

6. A computer-readable storage medium storing a computer-executable program usable to identify radio communication devices in a subject vehicle, the program comprising:
-
instructions for determining whether the subject vehicle is driving; instructions for, when it is determined that the subject vehicle is driving, performing a first search and second search to identify radio communication devices in a vicinity of the in-vehicle device; instructions for storing addresses of the radio communication devices identified by the first search and the second search; instructions for comparing the addresses of the radio communication devices identified by the second search with the addresses of the radio communication devices identified by the first search; and instructions for determining that a particular radio communication devices is inside the subject vehicle if that particular radio communication device'"'"'s address is identified by both the first search and the second search.
