Abstract: Disclosed is a repair unit (10) for a pod (11), especially a laser designation pod, including: a transportable casing (14); a bubble (18) attached to the casing (14), having a retracted state and a deployed state, the bubble (18) including an opening (46) for inserting part of a pod (11) and at least two projections forming tubes (50) for the hands of an operator, each tube (50) opening up in the bubble (18); and a gas supply device (22) for switching the bubble (18) front the retracted state to the deployed state. The casing (14) and the bubble (18) define an inner space sealed from outside pollutants in both the retracted state and in the deployed state.

Abstract: The invention relates to a method for maintaining equipment likely to go through at least a degraded state before failing, this equipment being provided with a data sensor, linked to a recorder, which is in turn associated with a processing unit, which comprises the following steps of: detection of states of the equipment from the recorded data, and by means of a hidden Markov model, determination of an optimal maintenance date as a function of a state of the equipment, of a predetermined aggregate usage time of the equipment, by using an optimal stop on PDMP, which comprises: a substep of calculation of a quantization grid made up of cells with, for each cell, the transition date, the state of the equipment on that transition date, the time spent in the preceding state, the probability of being in said state on said date, a substep of calculation of a discretized grid of remaining usage time for each cell of the quantization grid, a substep of calculation of the maintenance date starting from a state of the

Abstract: The invention relates to an optronics system equipped with: a detector cooler having a cooling machine, a cryostat, an IR detector placed in the cryostat, and a sensor for measuring the temperature TD of the detector; and a processing card which includes means for servocontrolling the cooling machine according to the temperature TD. The system includes a sensor for sensing the system's internal temperature TS, and the processing card includes means for calculating: the refrigerating time (TMF) based on the temperatures TD and TS, on each “on-off” cycle of the detector cooler, the trend of the drift in the refrigerating time TMF, as a function of the number of “on-off” cycles of the detector cooler, a sudden drift as a function of said trend of the drift of the TMF, and means for storing data used in said calculations; these data are aggregated data and not the measurements of temperatures TD and TS, nor said TMFs, in order to limit the size of the storage means.
