  • Patent number: 9322224
    Abstract: A coupler for coupling a first and a second section of a transmission line embedded in a first and a second component respectively, includes a first half-coupler including a first electrically conductive housing, a first electrically conductive structure, and a first structure of dielectric material, and a second half-coupler including a second electrically conductive housing, a second electrically conductive structure, and a second structure of dielectric material. When the first and second components are connected end-to-end, the first and second housings come into contact to form together an electromagnetic cavity, inside which the first and second conductive structures are separated from each other by the first and second dielectric structures, so as to allow the first and second conductive structures to be in electromagnetic communication with each other.

  • Patent number: 8950787
    Abstract: An ensemble including a pipe for transporting substances which can flow, the pipe having a structure forming a coaxial transmission line including: a first tubular layer of electrically conductive material; a second tubular layer of electrically conductive material; and at least one first layer of dielectric material mounted in-between the first and the second layers of electrically conductive material, such that: the first layer of electrically conductive material forms an outer conductor of a section of the coaxial transmission line; the second layer of electrically conductive material forms an inner conductor of the section of the coaxial transmission line, and further including an electromagnetic coupler coupling the coaxial transmission line with a complementary coaxial transmission line carried by a pipe complementary to the pipe.

  • Publication number: 20020086657
    Abstract: This telecommunications device (21, 22 or 23) forms part of a system comprising base stations (10, 12). This system permits the devices forming it to relay information among them. It is proposed to provide the devices with a plurality of transceiver devices (RX1, RX2, . . . , RXm, TX1, TX2, . . . , TXn) for exchanging information with other devices and/or base stations.

  • Publication number: 20020079980
    Abstract: This apparatus comprises an amplitude and phase-modulated signal transmitter. This transmitter is formed by a non-linear amplifier (30) for supplying signals based on a portable signal generator (25) to an antenna (10). The apparatus comprises an amplitude modulator (39) which is placed between the amplifier (30) and the antenna (10) and a phase modulator (37) which is placed at the input of the amplifier (30).

  • Patent number: 6329847
    Abstract: A radio device includes phase discriminator with a phase locked loop. Where when there is no phase locking, the output voltage of the phase discriminator remains constant, which provides considerable gain for loop. When there is phase locking, the phase discriminator produces an error proportional to the phase difference. An output of the phase discriminator has a constant amplitude with an input signal and a reference signal have different frequencies.
