US Patent 11376178 Using force sensors to determine sleep parameters

A support platform supports a mattress. The support platform includes legs. Force sensors are coupled to the legs or to the support platform. The force sensors are configured to sense a force applied to each leg or support platform. A controller is configured to receive at least one force stream from at least one of the force sensors. The at least one force stream represents a force sensed by the force sensor. The controller is configured to, in responses to receiving the at least one force stream, determine a sleep parameter from the following group of sleep parameters: bed presence, weight, heart rate, respiration rate, and motions. The controller is configured to output at least one or more of those parameters to an end user.
