Abstract
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.
Claims20
A bed system comprising:
- a mattress;
- a first sensor configured to sense a first parameter;
- a support platform supporting the mattress, the support platform comprising a plurality of legs;
- a plurality of force sensors, each of the plurality of force sensors configured to sense a force applied to one of the plurality of legs;
- and
- a controller configured to:
- receive a first data stream from the first sensor, the first data stream representing the first parameter sensed by the first sensor;
- receive at least one force stream from at least one of the plurality of force sensors, the at least one force stream representing a force sensed by the force sensor;
- create a comparison parameter based on a comparison of the force stream and the first data stream;
- and
- determine whether to send an instruction to drive a controllable device based on a comparison of the comparison parameter to a threshold.
A method comprising:
- monitoring a pressure at a bed;
- monitoring a set of force sensors mounted to a set of legs on the bed;
- generate a comparison parameter based on a comparison of the pressure to data from the set of force sensors;
- and
- sending an instruction to drive a controllable device based on the comparison parameter.
A bed system comprising:
- a mattress;
- a pressure sensor configured to sense pressure at the mattress;
- a force sensor configured to sense a force applied to the bed system;
- and
- a controller in data communication with the pressure sensor and the force sensor and configured to:
- receive the sensed pressure from the pressure sensor;
- receive the sensed force from the force sensor;
- generate a comparison parameter based on a comparison of the sensed force and the sensed pressure;
- and
- determine whether to send an instruction to drive a controllable device based on a comparison of the comparison parameter to a threshold.
