Abstract: An automobile vehicle airbag system includes a vehicle seat having a seat back rotatably connected to a seat base, with the seat base mounted on a seat frame. A seat base cushion is mounted on the seat frame upon which an occupant is seated. A thigh airbag is connected to the seat frame and positioned above the seat frame and below the seat base cushion in a thigh airbag uninflated condition. At least one airbag tether is connected to the seat frame and to the thigh airbag. A lap belt is connected to the vehicle seat and contacts a pelvis of the occupant. When inflated the thigh airbag pushes upward on the seat base cushion forcing the thighs and pelvis of the occupant upward into frictional contact with the lap belt, thereby mitigating against submarining of the pelvis beneath the lap belt.

The memory stores: a bloom filter set including an array of bits representing entries in a certificate revocation list; and a false positive set including a list of certificate entries falsely identified as being revoked. The transceiver receives from a second IoT device a message including a certificate. The bloom filter evaluation module receives the bloom filter set from a back office station and determines whether an identifier associated with the certificate is in the bloom filter set. The false positive comparison module receives the false positive set from the back office station and determines whether the identifier is in the false positive set. The control module permits communication between the first and second IoT devices based on whether the identifier is in the bloom filter and false positive sets.
