The invention pertains to a method of monitoring the quality of a mattress during its lifetime, wherein the mattress is an assembly of multiple separate parts, wherein the parts are mechanically interconnected, the method comprising during its lifetime, assessing at least one property of the mattress, determining whether or not the property meets a predetermined specification, and when the property does not meet the predetermined specification, identifying a part of the said multiple separate parts that corresponds to the property, removing the identified part from the assembly and optionally replacing the removed part with a replacement part, wherein the mattress that is monitored is manufactured by forming the mechanical interconnection with an adhesive, which adhesive has a first order phase-transition temperature between 80° C. and 180° C., at which temperature the adhesive undergoes a solid-liquid transition, and wherein before the said removing of the identified part, the adhesive with which this part is interconnected with other parts in the assembly is heated to a temperature above its phase-transition temperature, whereafter the identified part is grasped and pulled out of the assembly. The invention also pertains to a method of manufacturing a mattress suitable for use in this monitoring method.

Described herein are multifunctional smart beds and methods of operating thereof. Specifically, a multifunctional smart bed comprises a controller, configured to receive input from various sensors (e.g., load cells positioned in bed legs, thermometers, and/or microphones) and/or user. These inputs are analyzed and used to control various bed components to improve the sleep quality, to monitor users' health, score couple's relationship, and the like. For example, these inputs may be used to control the firmness of different mattress portions, change orientations of the head, torso, and/or leg sections, adjust the light, and the like. In some examples, the smart bed generates a report indicating one or more sleep duration, sleep depth profile, sleep scope, heart rate, breath rate, environment conditions, couple's relationship, and the like. Furthermore, in some examples, a multifunctional smart bed is also configured to control external devices in the same environment, e.g., smart switches, smart thermostats.

An apparatus (1) for positioning the body of a user (100), wherein the apparatus can be used in a seat or in the form of a rest, comprising a seating element (20), a pelvis and lumbar-spine module (13) and a computer unit (40), wherein the pelvis and lumbar-spine module comprises an adjusting element (117) and a sensor (113), and the seating element comprises an adjusting element (108) and three sensors (111, 112), wherein the sensors (111, 112, 113) sense seat-related and rest-related pressures, wherein the computer unit activates the adjusting elements, wherein a first and second sensor (112) and a third sensor (111) sense the seat-related pressure of the first and second ischial tuberosities (102) and of the coccyx (104), wherein the first and the second ischial tuberosities define an ischial-tuberosity level, wherein the adjusting element of the seating element compensates for the ischial-tuberosity level horizontally about the user's sagittal axis, and whereupon the adjusting element of the pelvis and lumbar-spine module tilts the user's pelvis (101) about the horizontal axis of the same until the seat-related and/or rest-related pressure of the coccyx has a value substantially equal to zero.

A method for customizing a mattress includes acquiring a three dimensional image of a body of a user and preparing, by a processor, a three dimensional model of the body of the user using the three-dimensional image. The method also includes dividing, by the processor, the three dimensional model into a plurality of cylindrical sections arranged parallel to each other and arrayed along a height of the three dimensional model, and determining a downward pressure to be exerted by at least one desired cylindrical section on the mattress. The method further includes determining, by the processor, one or more parameters associated with at least one portion of the mattress adapted to be arranged underneath the at least one desired cylindrical section when person lies on the mattress based on the determined downward pressure.

The disclosure relates to a bunk, in particular for a vehicle cabin. The bunk comprises a base plate, an upper layer, a plurality of supporting members vertically compressible and spaced apart from one another substantially over the whole surface of the bunk, a plurality of pressure sensors which are part of the upper layer and in an adaptable area comprising at least one area of the bunk, a moving mechanism configured to move at least some of the supporting members in the adaptable area parallel to the base plate, and a control unit connected to the pressure sensors and the moving mechanism. The control unit is configured to cause the moving mechanism to move the supporting members in the adaptable area as a function of the current pressure data provided by the pressure sensors, to locally change the density of the supporting members to provide a locally variable bunk firmness.

A respiratory assistance component is disclosed that changes shape when an electrical charge is provided. The amount of electrical charge that is applied may be based on values, characteristics, or user controlled parameters of the respiratory assistance system. The component may be all or part of a patient interface, a tube, a flow generator, and/or a sleep mat.

A vehicle seating assembly includes a seat base that has a first heating element. A seat back has a second heating element. A sensor is coupled to the seat base and is configured to obtain a weight data. A user-interface assembly is operably coupled to the first and second heating elements. A controller is in communication with the sensor to receive the weight data. The controller is configured to control the first and second heating elements in response to the weight data.

A smart chair and logging/warning assembly are disclosed. In some implementations, the smart chair includes a base arranged to receive a sitter, a sensor, and a transmitter. The sensor can be located within the base. Additionally, the sensor can take initial readings relating to the sitter on the chair for reference. Further, the sensor can take readings of the sitter while they are sitting and transmit information relating to the sitter's sitting to a computational device.

The present invention relates to a method of operating a smart mattress system enabling alarm control, wherein a user is allowed to transition to a light sleep state before an alarm time set by the user. Furthermore, an air mattress and an air pillow interlock with a user terminal so that the user can easily control the air mattress and the air pillow.

The present disclosure discloses a personalized mattress system and a mattress customization method. The personalized mattress system includes a client, an adjustable mattress device, and a cloud, wherein the client includes a user login unit, a user personal customization unit, a mattress control unit, and a data communication unit; the adjustable mattress device includes a data communication unit, a main control unit, an algorithm unit, a sensing unit, an adjustment unit, and a local data storage unit; and the adjustable mattress device acquires user customization information from the client or the cloud through the data communication unit and perform mattress adjustment.
