Latest Patents

One of Lignon's latest patents is an inertial measurement device designed to be carried by a vehicle. This apparatus includes a chassis and a turntable mounted on it. A first inertial measurement unit is attached to the turntable, which is connected to an electronic control unit that manages the motor for turning the turntable. A second inertial measurement unit is secured to the chassis. The control unit is capable of turning the turntable through one complete revolution with periodic alternating motion from a fixed initial angular position. It calculates the acceleration of the carrier vehicle by measuring data from both inertial measurement units, allowing for a comprehensive analysis of the vehicle's movement.

Another notable patent involves a method and device for resetting an inertial unit of a transport means based on information from a viewfinder. This innovative approach involves obtaining a horizontal velocity vector and coordinates from the inertial unit, as well as a horizontal line of sight from the viewfinder. By computing the angle between these vectors and filtering the resulting error through a Kalman filter, the inertial unit can be accurately reset, enhancing the reliability of the transport means.
