  • Patent number: 11031694
    Abstract: In an antenna, the outer conductor is formed of a first linear conductor, the first linear conductor having a length corresponding to one wavelength of a right-handed circularly polarized wave and circularly extended from a first feed point to a second feed point. The inner conductor is disposed inside the outer conductor and formed of a second linear conductor, the second linear conductor being different from the first linear conductor and having a length determined based on one wavelength of a left-handed circularly polarized wave. The inner conductor has a starting point of the second linear conductor connected to the first feed point and has an end point of the second linear conductor kept free from connection at a location inside the outer conductor, and causes current to flow in a direction opposite to the current flow in the outer conductor.

  • Patent number: 10933841
    Abstract: A detection system for vehicle includes a reader and a first detector. The reader is provided in a vehicle, transmits and receives radio signals, and transmits transmission signals including at least radio signals for supplying electric power. The first detector is driven by the radio signals for supplying electric power included in the transmission signals when receiving the transmission signals and can transmit first response signals output in response to the transmission signals to the reader. The first detector is disposed in a sitting area on a seat where the first response signals transmitted to the reader are blocked. The reader determines a sitting state of a passenger based on whether the first response signals are received in response to the transmission signals.

  • Patent number: 10184781
    Abstract: The purpose of the present invention is to provide a displacement detecting device capable of decreasing a measurement error, even when a diffraction grating is inclined or displaced to a direction other than a measuring direction. The displacement detecting device 1 comprising: a light source 2 for emitting light; a polarized beam splitter 7; a diffraction grating 11; a prism unit 16A (16 to 19) for shifting light path; lenses 14 and 20 for correcting light path; and an interfered light receiving unit 22A (22 to 30). The prism unit 16A for shifting light path shifts first diffracted light to a direction vertical to the measuring direction. The lenses 14 and 20 for correcting light path is arranged on a symmetrical axis of light paths and corrects light path when the diffraction grating 11 is inclined or moved to a normal direction of a grating surface.

  • Patent number: 10066924
    Abstract: A displacement detection apparatus can reduce a measurement error even when a diffraction grating is displaced and/or tilted to a direction other than the measurement direction. A displacement detection apparatus includes a light source which emits light, a luminous flux-splitting section, a diffraction grating, a diffracted light-reflecting section, a correcting lens, a luminous flux-coupling section, and a light-receiving section. The diffracted light-reflecting section reflects a first luminous flux and a second luminous flux so as to be perpendicular to one of measuring planes of the diffraction grating and be parallel to each other. The correcting lens is arranged between the diffracted light-reflecting section and the diffraction grating.

  • Patent number: 9810521
    Abstract: A displacement detection apparatus capable of stably and accurately detecting the amount of displacement. The length of a polarization maintaining fiber for transmitting the light from a light source to a displacement detector is set not to be equal to a length obtained by dividing, by the wavelength of the light source, a product of an even integral multiple of a length, which is obtained by multiplying twice the length of a resonator by the refractive index of the resonator, and a beat length obtained by a difference between the propagation constants of two polarization modes. Alternatively, the length of the polarization maintaining fiber is set to be larger than a length, which is obtained by dividing, by the wavelength of the light source, a product of a coherence length and a beat length obtained from a difference between the propagation constants of two polarization modes.
