  • Patent number: 10870171
    Abstract: The present invention relates to a method for defining a sequence of relative positionings of a laser head 1 in relation to a part for the machining of a texture etched on the two-dimensional or three-dimensional surface 7 of the part modelled by a 3D meshing, comprising: a step 100 of definition of N machining layers intended to be performed in succession, a step 200 of definition, for each machining layer, of patches intended to be each machined from a single position of the laser head 1, comprising closed patches 15, the boundary of which is not affected by the laser ray 2, a step 300 of validation of the closed patches 15, successively from the machining layer 1 to the machining layer N. Open patches whose boundary is affected by the laser ray 2 being defined for any areas which could not be machined from validated closed patches 15. Optionally, the method also comprises a step 400 of merging of the validated closed patches 15 into groups 50 of patches.

  • Patent number: 5032833
    Abstract: Optimum routing for communications between a central control unit (CCU) and remote units (nodes), such as electricity meters, distributed on an electrical power line is established by broadcasting from the CCU an interrogation signal to be received by the remote units. In response to a receipt of the interrogation signal, each remote unit returns an acknowledgement signal, time multiplexed with the acknowledgement signals of the other remote units, to the CCU which determines which units, if any, are "mute", i.e., have not acknowledged. The CCU then selects remote units in proximity to the mute remote units if it has already a good knowledge of the network or at random otherwise, to function as relays and repeats interrogation of the remote units via the relays. This process is repeated, if necessary, until communication paths between the CCU and all remote units are established directly or via delay units, to form maps.

  • Patent number: 4968970
    Abstract: The transmitter in a power line communications system applies to the power line encoded logical-one and logical-zero bit signals consisting of signals formed respectively of predetermined different sequences of frequencies. The receiver, coupled to the power line, includes a first homodyne, non-coherent, quadratic demodulator for demodulating the logical-one bits and a second for demodulating the logical-zero bits. The first demodulator produces, locally, and in first and second channels, respectively, a first reference signal that is a replica of the logical-one bit sequence of frequencies and a second reference signal that is the replica in quadrature. The second demodulator produces, locally, and in third and fourth channels, respectively, cooresponding third and fourth reference signals for the logical-zero bit sequence. Each of the four reference signals is applied to a corresponding analog multiplier for multiplication by the input signal in each channel.
