An air system for use in an air bed system can include a manifold and one or more valves. The manifold can define a an inlet, an outlet, and a vent fluidically connected to atmosphere. A method of operating an air bed system can include deflating an air chamber through the vent in a first valve configuration and through the vent and an exhaust port in a second valve configuration.

A bed has a mattress. A first wireless charging array is positioned on a top side of the mattress nearer a head of the mattress. A pillow is configured to be positioned atop the first wireless charging array. The pillow includes a second wireless charging array located on an underside of a pillow. The second wireless charging array is configured to receive energy from the first wireless charging array. A companion device is configured to use the energy. An energy storage device is within the pillow. The energy storage device is configured to store charge received by the first wireless charging array. The energy storage device is configured to supply power to the companion device.

A chair-type massage machine includes a main body on which a person to be treated is to be seated, a holding part at least part of which is placed inside a container recess to hold a first operation unit, and a moving mechanism for moving the holding part. The holding part is reciprocatably moved between a first position in which the first operation unit is contained in the container recess and a second position in which the first operation unit is exposed. The chair-type massage machine further includes a second operation unit for moving the holding part.

A method may comprise receiving, at a central controller, a command, from a remote control, to adjust a feature of a first component of an air mattress framework; relaying, from the central controller, the command to the first component; receiving from the first component at the central controller, an indication of the success of the command; and relaying the indication from the central controller to the remote control.

A system used to fit fitted sheets over a mattress. The system allows a user of the system to keep the fitted sheets unwrinkled when the user decides to lie on the mattress that uses the system. The system comprises of a rectangular housing, a plurality of mounts, a plurality of gear motors a plurality of pulleys, a plurality of straps, a motor speed controller that is operatively connected to each gear motor, a connector that is fixedly attached to an end of each strap, and a fitted sheet that defines a plurality of receivers that are positioned concentrically around a central axis of the fitted sheet, the connector that is fixedly attached to the end of each strap attaches to each receiver of the plurality of receivers of the fitted sheet.

A bed has a mattress. One or more temperature sensors are used, each sensor configured to: sense a temperature for the sleeper; and transmit, to a controller, temperature readings; one or more pressure sensors, each pressure sensor configured to: sense a pressure applied to the mattress by the sleeper; and transmit, to a controller, pressure readings. A controller may include a processor and memory, the controller configured to: receive, from the temperature sensors, the temperature readings; determine a skin temperature for the sleeper based on the temperature readings; receive, from the pressure sensors, the pressure readings; determine at least one cardiac parameter for the sleeper; and determine, from the skin temperature and the cardiac parameter, a core temperature for the sleeper that is different than the skin temperature and represents thermal state of a core of a body of the sleeper.

According to an aspect of the invention there is provided a system for use in monitoring one or more physiological states of a user, the system comprising one or more processors configured to: receive a pressure signal representing pressure within a cushioning layer supporting at least a portion of a user and an acoustic signal representing acoustic vibrations within the cushioning layer; and determine, based on the pressure signal and acoustic signal, the one or more physiological states of the user.

A control system for controlling an adjusting drive for an item of furniture includes a control device connected to the adjusting drive, and a first operating unit. The control device is configured to receive signals from the first operating unit transmitted wirelessly via a transmission unit over a first transmission link, and to control the adjusting drive as a function of the signals received. The control device is also configured to receive further signals from a second operating unit transmitted wirelessly via the transmission unit over a second transmission link and to control the adjusting drive as a function of the further signals received. The second transmission link differs from the first transmission link.

According to an embodiment, a control device includes multiple operation buttons, an acceptance part, and a displayer. The multiple operation buttons can control an operation of a movable part of electric furniture. In a first state in which the acceptance part receives a first input, the displayer displays a first display between the multiple operation buttons. A bed system is provided in which the ease of use can be improved. A control device and electric furniture are provided in which the operationability can be improved.

A method for correcting a massage position and a massage chair for performing the same includes allowing a shoulder height measurement module to measure a shoulder height of a user, allowing a hip bone position prediction module to predict a hip bone position through a preset prediction method by using the shoulder height measured by the shoulder height measurement module, allowing a massage position determination module to determine a plurality of determination massage positions and a plurality of correction massage positions spaced from the determination massage positions by a predetermined distance on the basis of the hip bone position predicted by the hip bone position prediction module, and allowing a massage ball assembly control module to control a massage ball assembly so as to massage the determination massage positions and the correction massage positions determined by the massage position determination module.
