A tire damage detection system for a vehicle includes: a tire; at least one sensor disposed in association with the tire to detect a noise signal when the tire rolls on a road surface to move the vehicle, the noise signal having a plurality of frequency peaks in a frequency spectrum of the noise signal; and a processor to monitor target frequency peaks of the frequency spectrum to detect damage of the tire, and to generate an alert signal in response to the detection of the damage of the tire.

A method for monitoring performance of at least one component on a moving platform, the method including receiving sensor data for the at least one component, along with supplemental data, at a processing node; and processing the sensor data, the processing using the supplemental data to filter the sensor data.

A device for inspecting tires of large dimensions, in particular for civil engineering vehicles, comprises: a rotationally driven tire support (10) designed to support a tire (20) to be inspected in position so that its axis of rotation is substantially horizontal, said support comprising means for rotating the supported tire; an ultrasound inspection device (1) provided with an inspection head (5) that is freely mounted radially and axially, a module (8) for retrieving and processing echo data retrieved during inspection phases, and a system for controlling the movement of the inspection head (5) inside the tire to be inspected, in particular along the inner wall of the crown area of said tire to be inspected.

A sound measurement system intended to be installed on a motor vehicle, the system comprising: a microphone, an element for supporting the microphone, mechanical means for protecting the microphone against various projections (water, dust, etc.) from the environment of the vehicle, and mechanical means for protecting the microphone from airborne noise originating from the routing of the sound wave between the source and the measurement (cavity noise) and from the environment of the measuring system (turbulence around the measuring device), the various mechanical protection means being separate or combined. A motor vehicle may be provided with such a system.

In order to obtain information about a salt-state of a road independently of drivers, a method that generates information about the salt-state of a road is specified that includes a determination of salt-state-dependent measurement values, processing of the measurement values into information about the salt-state of the road and outputting of the information about the salt-state of the road. A corresponding device that generates information about the salt-state of a road comprises sensors that determine of salt-state-dependent measurement values, a processing unit that is configured to process determined measurement values into information about the salt-state of the road, and output the information about the salt-state of the road.

A method for determining a running parameter of a vehicle travelling on a road, based on a measurement of a sound signal produced by a tire of the vehicle, and on measurements and estimations of running conditions effected in real time.

A method for monitoring performance of at least one component on a moving platform, the method including receiving sensor data for the at least one component, along with supplemental data, at a processing node; and processing the sensor data, the processing using the supplemental data to filter the sensor data.
