Abstract: A method for obtaining the profile of the outer surface (22) of a medium (21) having a median plane (23) comprising the following steps: obtaining two time signals A and B (1002), for, at each instant, a same geometrical target on a readout line of the outer surface (22); determining at least one Doppler frequency (2001) associated with each time signal A and B; sampling each time signal A and B (2002) at a frequency greater than 2 times the Doppler frequency to obtain a payload signal; determining an envelope (2004) of the payload signal of each signal A and B; performing a relative combination between the envelopes of each signal A and B (3001) to obtain a monotonic and bijective function F; and determining the profile of the outer surface (3002) using a calibration of the function F.

Abstract: A method for determining a road condition is carried out aboard a vehicle driving on the road and comprises the following steps: capturing the noise created by the friction between at least one tire and the road; analyzing the noise signal in the high frequency range to determine whether the road condition is dry or not; and, in case the road condition is not dry, analyzing the noise signal in the low frequency range to determine whether to road condition is wet or damp.

Abstract: A method for estimating a water height on a roadway where a tire of a vehicle is running, the mounted assembly being placed in a wheel arch of the vehicle, comprises the following steps: fixing a sensor onto the vehicle; obtaining a frequency signal from the sensor corresponding to the running of the vehicle at speed V on the roadway covered with a water height heau; isolating a part of the frequency signal, bounded by two strictly increasing frequencies, which is sensitive to the height heau; determining an energy vector linked to the part of the frequency signal; and obtaining the water height on the roadway using a function taking account of the energy vector and the speed V of the vehicle. The sensor is a microphone, and the part of the frequency signal extends at least partly beyond 4 kHz.

Abstract: A system for managing a plurality of client processes, comprising a client task within which the client processes will be executed and a manager task running at a higher priority than the client task, the manager task queuing the client processes into the client task in priority order, wherein the manager task kills the client task when a current one of the client processes is not completed within a predetermined time period.

Abstract: A computer system and method for operating a computer system is provided which comprises a core operating system and a system space having a number of memory locations. The core operating system is arranged to create a number of protection domains to partition the system space into a core operating system space and a plurality of partitions. A partition operating system, a partition user application, and a partition alarm handler is provided in each partition. Each partition operating system provides resource allocation services to the respective partition user application within the partition. An alarm dispatcher and a system alarm handler is provided in the core operating system space. The alarm dispatcher is configured to receive alarms and to dispatch the alarms to one of the alarm handlers.

Abstract: An alarm management system is provided which includes a hierarchical database of alarm source identifiers. Each alarm source identifier is associated with a corresponding software entity capable of generating an alarm. The system further includes a corresponding alarm controller for each software entity and an alarm processor. The alarm processor receives an alarm from one of the software entities, accesses the hierarchical database to identify a parent software entity of the one of the software entities, invokes a corresponding alarm controller for the one of the software entities and invokes a corresponding alarm controller for a corresponding alarm controller for the parent software entity.
