Abstract
A vehicle includes a motion sensor and a control processor. The motion sensor optically detects motion of the vehicle with respect to an underlying surface. The motion sensor includes a variable focus imager. The control processor receives information from the motion sensor and calculates location of the vehicle, speed of the vehicle and/or acceleration of the vehicle.
Claims20
A vehicle, comprising:
- a motion sensor that optically detects motion of the vehicle with respect to an underlying surface, the motion sensor including a variable focus imager;
- and,
- a control processor that receives information from the motion sensor and calculates at least one of the following:
- location of the vehicle,
- speed of the vehicle,
- acceleration of the vehicle.
3 more elements
A motion detection system, comprising:
- means for optically detecting motion with respect to an underlying surface;
- and,
- means for calculating at least one of the following from the optically detected motion:
