Abstract
A sensor system is sensitive to the determination of activity, movement and position of a passenger in a vehicle. In particular, the determination of the position and movement of passengers in a vehicle can be enhanced by providing groupings of transmitting antennas and/or multiple infusion antennas. The sensing system is able to determine the movement and activity of the passengers at various ranges and locations within the vehicle.
Claims17
A sensing system comprising:
- a group of transmitting antennas operably connected to a car seat;
- in a first mode, one signal is transmitted on more than one transmitting antenna of the group during a first integration period,
- in a second mode, the group of transmitting antennas are adapted to transmit frequency orthogonal signals on each transmitting antenna of the group during a second integration period;
- a plurality of receiving antennas, each one of the plurality of receiving antennas adapted to receive the plurality of signals transmitted;
- and
- a processor adapted to determine a measurement of signals received during the first mode or the second mode, wherein the processor is further adapted to process the determined measurements to determine position or movement of a passenger.

A sensing system comprising:
- more than one infusion transmitting antennas adapted to infuse signals into a passenger of a vehicle, each infused signal frequency orthogonal to each other infused signal transmitted during an integration period,
- a plurality of receiving antennas, each one of the plurality of receiving antennas adapted to receive infused signals infused into the passenger;
- a processor adapted to determine a measurement of each one of the infused signals received, wherein the processor is further adapted to process the determined measurements to determine position or movement of a passenger;
- and
- wherein in a first mode, one signal is transmitted on more than one transmitting antenna of the group during a first integration period,
- wherein in a second mode, the group of transmitting antennas are adapted to transmit frequency orthogonal signals on each transmitting antenna of the group during a second integration period.
