The present disclosure relates to a bed-integrated electromagnetic field apparatus for controlling movement of a microrobot, and a method for driving a microrobot by using the same. A bed-integrated electromagnetic field apparatus according to the present disclosure can accurately control the movement of a medical device that can be inserted into a human body, such as a microrobot, and enables reduction of the size of the apparatus so as to be used in a medical procedure for diagnosis and treatment of vascular disease and the like.

The present application discloses a bedsheet fastening device for fastening bedsheet to a mattress and holding it in place. The device comprises magnets configured to hold the bedsheet to the mattress and prevent it from rumpling. In some embodiments, the device comprises a plurality sets of magnets with each set of magnets comprising a first piece of magnet and a second piece of magnet. The first piece of magnet is affixed to the mattress and the second piece of magnet can be attached to and removed from the first piece of magnet. The plurality sets of magnets are arranged on the mattress and can hold a bedsheet securely in place. The bedsheet can be removed by separating the first piece of magnet from the second piece in each set. In some embodiments, magnets are housed in a protective cover or a holder, for example, an insert or a panel.

An array of linear foam strips designed to be vertically stacked with their linear axes parallel and vertically aligned under a region of a mattress that requires a raised contour on its top face to alleviate a medical condition or to repair a sag in the mattress. The foam strip arrays come in 24 or 32 inch lengths to correspond to the width of standard mattress. Each linear foam strip has a different width but none of the strips are within 25% of the width of any other foam strip. The widths of the four different foam strips in the array has been carefully sized to allow the best possible combinations to develop the proper height and side slope of the contour developed in the mattress's top face.

A removable cushion for a chair having an outer surface and an inner foam, as well as at least one magnetic member. The inner foam and the outer surface are formed from the same polymer, with the outer surface forming an integral skin over the inner foam. The outer surface defines an upper surface and a lower surface. The lower surface is structurally configured to be positioned in an abutting relationship with a seating surface of a chair. The at least one magnetic member is embedded within one of the outer surface and the inner foam, the at least one magnetic member positioned closer to the lower surface than the upper surface of the outer surface. A chair having the cushion, and a mold is likewise disclosed, as is a method of manufacturing the cushion.

The disclosed bedsheet system includes a middle portion, a foot connector, and a head connector that allows for quick removal and/or addition of sheets. The middle portion has a length and a width defining a plane, the length has a first end and a second end. The foot connector is attached to the first end of the middle portion and has at least one sheet connector mechanism. The head connector is attached to the second end of the middle portion and has at least one sheet connector mechanism. The foot connector and the head connector extend generally perpendicular from the plane of the middle portion.

A body supporting device system is provided comprising: a body supporting device configured to support at least part of a body; a pressure sensing layer comprising a plurality of pressure sensors arranged in a sensor pattern, the plurality of pressure sensors being each configured to sense pressure on the surface of the body supporting device at a corresponding sensing location; and a firmness adjusting layer comprising a plurality of actuators arranged in an actuator pattern, the plurality of actuators are each configured to control the firmness of the surface of the body supporting device at a corresponding adjusting location based on some or all of the pressures sensed by the plurality of pressure sensors

A magnetic coupler for attaching a mattress to a bed foundation includes a magnet assembly, a target assembly, and a shunt. The magnet assembly includes a housing and a magnet, wherein the housing is configured to couple the magnet to the mattress. The target assembly is configured to couple a target to the foundation. The shunt is disposed within the housing of the magnet assembly or in the mattress. The magnet assembly and the target assembly are releasably attached when the magnet is magnetically coupled to the target.

A therapeutic orthopedic mattress for pets includes a top cover, a first layer covered by the top cover, and a second layer underlying the first layer. The mattress also includes an antennae comprising an elongated wire having a first end positioned proximate a first end of the first layer and a second end longitudinally spaced apart from the first end proximate a second opposing end of the first layer. The antennae is spread out between the first layer and the top cover. In addition, the method includes a microprocessor coupled to the first end of the antennae and is configured to distribute a plurality of sequences of intermittent electrical signals along the antennae to the second end. The mattress also includes a plurality of magnetic discs and far infrared radiation discs dispersed over a top surface of the first layer.

The present disclosure describes methods and apparatus for a modular headboard that is assembled by magnetically coupling of a plurality of magnetic mounting units to one or more magnetic base boards. The present disclosure also describes a set of pre-formed liners designed to maintain the cleanliness of the floor of an automobile, the sheets comprising adhesive regions and, in some embodiments, a textured region on the top surface of the sheets.
