Appeal 2007-1854
Application 10/920,345
Appellants’ invention is directed to a tire breakdown warning device.
Claim 1 is illustrative and reproduced below:
1. A tire breakdown warning device which provides a warning when a
breakdown of a pneumatic tire is found on the basis of detection signals
detected by at least one temperature sensor for detection of temperature of
the pneumatic tire, the tire breakdown warning device comprising:
a vehicle mount unit having a processing section for processing the
detection signals from the at least one temperature sensor and a warning
section for providing a warning of the tire breakdown,
the processing section calculating a value of temperature of each
detection signals input thereto and determining whether or not the calculated
temperature value exceeds a preset threshold value of breakdown
temperature,
the warning section providing a warning when the processing section
determines that the calculated temperature value exceeds the preset threshold
value of breakdown temperature,
wherein the processing section calculates each value of the amount of
temperature rise in a unit of time at each temperature detected and
determines whether or not the calculated temperature rise amount value
exceeds a preset threshold value of the amount of breakdown temperature
rise corresponding to each temperature, the warning section providing a
warning when the processing section determines that the calculated
temperature rise amount value exceeds the preset threshold value of the
amount of breakdown temperature rise, and
wherein the at least one temperature sensor is embedded in the
vicinity of at least one end of at least one tire constituent component which
is placed in the pneumatic tire and which is vulnerable to break down.
The Examiner relies on the following prior art references as evidence
in rejecting the appealed claims:
