摘要:
The invention concerns a process for manufacturing a double-layer electrolyte/electrode electrochemical sub-assembly comprising a positive composite electrode layer and a superimposed electrolyte layer, said layers each containing an ionically-conducting macromolecular material and having at their interface a physical and chemical continuum between the macromolecular material of the electrolyte and that of the electrode, and the sub-assembly so obtained. The process consists in depositing one of the layers on a support from a fluid phase containing the constituents of this layer, partially cross-linking the layer, and then spreading the other layer on this partially cross-linked layer from a fluid phase containing the constituents of the other layer and capable of dissolving the macromolecular material of the first layer deposited on the support. Application of the double-layer sub-assembly to the fabrication of electrochemical cells in the form of thin layers.

A multistatic radar surveillance system includes transmitter elements and receiver elements arranged according to a zone to be monitored, and a command and control unit that configures the elements and collects information relating to objects detected by the receiver elements. Each transmitter element transmits a signal, the bandwidth of which is substantially equal to the totality of a frequency band B allocated to the system. Each transmitter element transmits a common waveform to all of the transmitter elements, and the waveform is modulated by a binary signal specific to the element in question, this signal allowing each of the receiver elements receiving a signal to identify the transmitter element at the source of this signal. The coding applied to the waveform is defined so that the spread spectrum caused to the signal transmitted by the latter does not exceed the frequency band B allocated to the system.

A seam for use in a vehicle armrest or other interior component. The seam includes a first material and a second material joined to the first material. The seam also includes a T-member connected to the first material and the second material to form a French seam appearance on the outer surface of the material. The T-member is then used to align with a groove in a foam of an armrest or other interior component to create an exterior seam on an armrest or interior component of a vehicle. The seam is created using a guide member attached to a sewing machine that will allow for sewing of the first material and second material to the T-member in a simultaneous process at a predetermined speed thus increasing efficiency of manufacturing the upholstery panel and reducing costs to the manufacturer.

The invention relates to the field of electromagnetic detection systems operating in bistatic mode, in particular to UHF/VHF bistatic radars. The method according to the invention consists in the simultaneous use of signals transmitted by one or more transmitting sources on separate frequency channels. The method includes a step of multichannel reception and separating channels. Additionally, the method includes a step of analysis of the signals received channel by channel, wherein the analysis is performed by correlation of the signals received with copies of the time and frequency shifted reference signals. The reference signals are constituted by the signals received from transmitting sources by direct transmission with a step of integration of the signals analysed, channel by channel, and a step of detection. The method according to the invention enables a signal to be used whose band-width is equal to the band covered by the set of channels used, which improves the contrast and distance resolution of the system implementing said method compared with the systems known from prior art.
