A multifunctional mattress having a mattress body and a heating/cooling pressurization apparatus connected to the mattress body; the mattress body comprises independent pressurized circular balloons, alternatingly pressurized square balloons, heating/cooling air supply tubes, and pressurized tubing; the two sides of said heating/cooling air supply tubes are provided with small blow holes; the independent pressurized circular balloons (3) has a surface layer and a bottom layer; the surface layer and bottom layer are joined to form a plurality of independent closed balloons (33); at a position corresponding to the head are independent pressurized circular balloons; the alternatingly pressurized square balloon areas can be inflated or deflated by means of balloons causing the upper layer of sealed balloons to rise or fall.

A heating system includes a sensing and tracking module to sense length in at least one dimension of an object to-be-heated in a previously determined area. A light source module has at least one light source that can change its lighting direction and can also change its beam angle e along the at least one dimension. A control module is provided for regulating light emitted by the light source module onto the to-be heated object along the at least one dimension to match with the length of the to-be-heated object based on the length sensed by the sensing and tracking module. The heating system described above and a bed incorporated having this kind of heating system may automatically adjust its output power according to the physical characteristics of the object to-be-heated to avoid heating unrelated object, area or space so as to ensure high energy efficiency.

A bedding climate control apparatus that delivers, in a quiet manner, forced airflow from a fan/blower within a housing to selectively deliver tempered (heated via a thermal element) and untempered (room temperature) air through a flexible hose to bedding. The quiet manner is attained with acoustic foam in the path of incoming airflow to the fan/blower and by oversizing each of the components that create a pressure drop including the capacity of the fan/blower over what is needed to deliver a required amount of airflow. Temperature may be set remotely via a wireless remote control and via a Bluetooth enabled device.

A climate-controlled bed capable of adapting to the needs of a sleeper via a closed loop feedback control system is provided. The bed includes a thermoelectric energy source, a sensor configured to monitor a physiological temperature of a sleeper, and a control system that regulates a temperature of the bed via the thermoelectric energy source. The control system can utilize data from the sensor to determine optimal thermal needs of the sleeper. The control system can also vary the temperature of the bed during a sleep cycle based on at least one predetermined sleep factor, such as the natural circadian temperature cycle.

A temperature-regulating mattress system provides dynamic adjustment of temperature and other parameters throughout a user's sleep cycle to maximize the quality of the user's sleep, Features of the system may include: (a) heating and cooling temperature regulation (with dynamic custom profiles that control humidity and are dual-zone); (b) smart controls (with remotes and apps that learn from users to optimize settings and work with smart home products such as Alexa and interactive lighting systems); (c) comfort (with a mattress that provide the necessary support for its users); and (d) sensors used for temperature and humidity estimation algorithms, control mechanism, and additional inferences from those sensors (pose, enrichment of biometric sensing data, etc.).

A patient support apparatus includes a frame having a patient support deck. A footboard is removably coupled to the frame. A compression therapy module is located inside the footboard or is mounted to a foot section of the frame. A sleeve port is pneumatically coupled to the compression therapy module and is located on the foot section. The sleeve port is configured for attachment to at least one tube extending from a compression sleeve worn on a limb of a patient. Control circuitry is coupled to the frame and is operable to control functions of the patient support apparatus and to control the compression therapy module. A graphical display screen is coupled to the control circuitry and displays user inputs that are selected to control functions of the patient support apparatus and the compression therapy module.

A temperature modulation system for a bed, blanket, or other furniture includes a fluid for moderating temperature change, a number of conduit circuits for directing the fluid through respective zones, a control unit including a thermoelectric device for modulating temperature of the fluid, and a pump. Each of the conduit circuits selectively and independently directs fluid through its respective zone in order to produce a temperature within the zone that is independent of the temperature outside the zone. The system also includes an arrangement of one or more zones in an arrangement in which the control unit is programmed to vary the zone temperature over time according to a schedule.
