Abstract: In an emission process for remote sensing, pulse signals (630) are periodically produced in elementary time windows spaced one pulse period (T) apart, and waves corresponding to those signals are emitted towards remote objects, so as to enable to monitor waves transmitted by those objects upon receiving the emitted waves. The emission of those waves is periodically prevented, according to at least one inhibition period (3T, 5T) proportional to the pulse period and equal to at least three times that pulse period. Parameters are set, suited to producing measurement information on the objects from the wave monitoring, based on at least part of a frequency content of the transmitted waves to which the pulse and inhibition periods contribute. Applications to lidars, radars, active sonars and ultrasound monitoring.

Abstract: A method and apparatus for providing a security mechanism on a mobile device are described. The method and apparatus include determining a location for a device having a distance from a first location, determining if the distance is greater than a first threshold value, initiating an operating condition if the distance exceeds the first threshold, including a security measure to prevent unauthorized use and initiating a security timer, determining if the distance does not exceed a second threshold value after the distance has exceeded the first threshold value before the security timer reaches a time threshold, terminating the at least one security measure if the distance from the first location does not exceed the second threshold value before the time threshold, and initiating a further operating condition if the distance exceeds the third threshold, including a second security measure more severe than the at least one first security measure.

Abstract: Device and method for inserting error correcting codes and for reconstructing data streams, and corresponding products The present invention relates to a device (1) for inserting error correcting codes into data streams (11) intended to be sent in packets in a network (8), a device (9) for reconstructing data streams (13), and corresponding methods and products. The insertion device comprises a unit (3) for identifying resynchronization indicators dispersed in the data streams and a unit (4) for determining successive segments in these streams, the segments forming partitions of the data lying between two consecutive resynchronization indicators. It also comprises a unit (6) for allocating a set of error correcting codes to each of these segments, these sets of codes having decreasing sizes between any two of the consecutive resynchronization indicators. Preferably, the device also comprises a data interleaving unit (7).
