Patent ID: 8717179

Claim:
An apparatus comprising: a stroller having a frame and a seat, wherein the seat comprises a pliable fabric and has an upper surface and a lower surface; a fixed plate secured to the frame of the stroller; a flexible plate comprising a resiliently flexible plastic, wherein the flexible plate is in close association with the lower surface of the seat of the stroller; and a sensor mounted on the fixed plate; wherein at least a portion of the flexible plate has a planar shape and is biased to maintain its original planar shape, wherein the flexible plate engages the sensor mounted on the fixed plate by bending of the flexible plate when a sufficient weight is present on the seat of the stroller, wherein the flexible plate is separated and disengaged from the sensor when a sufficient weight is not present on the seat of the stroller due to at least the planar portion of the flexible plate being biased to maintain its original planar shape, and wherein the sufficient weight is a weight on the seat of the stroller that is sufficiently heavy to cause the flexible plate to bend and engage the sensor.
