Latest Patents

One of Sekiya's latest patents is a vehicular position estimation system. This system determines the position of a portable terminal by enabling multiple in-vehicle communication devices to wirelessly communicate with it. The system includes a distance index value acquisition portion that acquires a distance index value indicating the distance between the communication devices. It also features a normal range storage portion that stores data indicating a normal range of the distance index value. Additionally, a communication device diagnosis portion determines whether the in-vehicle communication device is functioning properly. If the distance index value between a diagnosis target device and at least one different device falls within the normal range, the system concludes that no failure occurs in the diagnosis target device.

Another notable patent is an antenna device that comprises three antennas. The first antenna has a directional gain at a low elevation angle that is higher than its gain at a high elevation angle. The second antenna has a higher directional gain at the high elevation angle compared to the first antenna. It transmits and receives radio waves with an electric field direction that intersects with the waves from the first antenna. The third antenna also has a higher directional gain at the high elevation angle than the first antenna, transmitting and receiving radio waves with an electric field direction that intersects with the waves from the second antenna.
