Abstract: The device comprises at least one frame, a first group of infrared ray emitters and a second group of infrared ray emitters, said groups framing a touch interaction space, the scanning of this space being performed by the successive activations of the emitters of the first group then of the second group, wherein, for the first group of emitters and for the second group of emitters: each emitter is associated with a subgroup of receivers, the receivers of said subgroup being arranged facing said emitter; the scanning cycles are initiated according to set time periods, a scanning cycle comprising a complete scan of constant duration according to the first group of emitters and a complete scan of constant duration according to the second group of emitters; all of the emitted rays not received defining one or more shadow areas.

Abstract: A process for routing virtual links in a frame-switching network including a plurality of source and/or destination terminals of the frames, in which frame switches are connected to one another by physical connections, with each virtual link being defined, for a point-to-point type, by a path through the network between a source terminal and a destination terminal, and, for a multipoint type, by a plurality of paths through the network between a source terminal and a plurality of destination terminals. The process performs the routing of links by minimizing at least one cost function on a set of solutions satisfying at least one predetermined topological constraint.

Abstract: A method for routing virtual links in a frame switching network including a plurality of source terminals and/or destination of the frames, frame switches being connected together through physical connections, each virtual link being defined, for a point-to-point type, by a path through the network between a source terminal and a destination terminal and, for a multipoint type, by a plurality of paths through the network between a source terminal and a plurality of destination terminals. The method carries out routing of the links while observing a segregation constraint with regard to triplets of consecutive switches belonging to the oriented loops, so as to allow verification of determinism of the network.

Abstract: Embodiments of the invention enable the integrity of data processed by a switch to be guaranteed better than 10?9 undetected erroneous frames per flight hour. To do this, rules for disabling ports are included in the switch management program. These rules include a maximum absolute admissible number of erroneous frames, to a maximum relative rate of admissible erroneous frames and a minimum number of erroneous frames constituting a significance threshold. Random errors are detected at the level of each frame due to the insertion of a CRC. Deterministic or data-dependent errors able to deceive systematically the CRC check are made random by means of a frame index.

Abstract: A data integrity checking system in a frame-switched on-board network, including at least first and second asynchronous transmitter terminals, with the second transmitter terminal being in charge of monitoring the first transmitter terminal, and at least first and second receiving terminals, with the second receiving terminal being in charge of monitoring the first receiving terminal. The system includes a first multicast virtual link connecting the first transmitter terminal to the receiving terminals, a second virtual link connecting the first receiving terminal to the second transmitter terminal, the second virtual link not passing through any of the switches that are common to the branches of the first virtual link, a third virtual link connecting the second transmitter to the first receiving terminal in order to transmit thereto the result of an integrity check on the data received by the first receiving terminal.

Abstract: Method and device for monitoring the validity of at least one parameter which is calculated by an anemometeric unit of an aircraft. The device (1) includes means (13) for taking into account n first data, each dependent on said parameter being monitored, n being greater than or equal to 1, means (15) for taking into account p second data, p being greater than or equal to 2, each of which depends on at least one value obtained from at least one data source (Si) external to said anemometeric unit (2), means (18) for calculating, for each of the second data, a difference between this second datum and a first datum of the same type, means (21) for comparing the absolute value of each of said differences with a threshold value, and means (23) for deducing from said comparisons that said parameter is invalid if the absolute values of at least two of the various differences are greater than the corresponding threshold values.
