A method can be provided that includes measuring sound waves using a sound measuring device, determining, at a central controller of an air mattress system, one or more parameter values of the sound waves, comparing the one or more parameter values with values, ranges, or patterns indicative of snoring, identifying a snoring state of a user, and initiating, with the central controller, a change to one or more adjustable features of the air mattress system.

A foldable bed includes first and second base frames, first and second rods fixed respectively to the first and second base frames, a first support frame mounted turnably to the first base frame, a first jack member coupled between the first rod and the first support frame for driving movement of the first support frame, and at least one reinforcing unit. The reinforcing unit includes a first reinforcing plate mounted on one of the first and second rods. When the first and second base frames are in an unfolded position, the first reinforcing plate is brought into abutting engagement with the other one of the first and second rods so as to distribute a pressure from the first jack member to the second base frame through the second rod.

An adjustable bed base has a stationary frame. An articulated deck is attached to the frame. The deck may be flat or fully articulated depending upon the position of linear actuators which are secured to the frame at one end and to a brace at the other end. The deck may be further inclined due to slotted mounting brackets, thereby allowing access to components below the deck members.

An adjustable bed base has a subframe which may be raised and lowered relative to a stationary frame by primary linear actuators. A deck is attached to the subframe. The deck may be flat or fully articulated depending upon the position of secondary linear actuators which are a part of a subframe module. The subframe module may be secured to the stationary frame of the adjustable bed base. The deck may be inclined by extending one of the primary linear actuators more than the other regardless of the positions of the deck members.

An air bed system including a plurality of peripheral devices and a pump unit configured to adjust a firmness of an air mattress, the pump unit including a pump. The system further includes a controller configured to execute instructions that cause the pump unit to wirelessly pair with at least one of the plurality of peripheral devices. The pump unit is configured to receive at least one control signal addressed to the at least one of the plurality of peripheral devices, and transmit the at least one control signal to the addressed device.

A transmission device of a hospital bed contains: a main motor, a connection rod unit, a gear unit, and a driver. The gear unit includes a first coupling post, a second coupling post, a first gear, a second gear, a third gear, a third coupling post, and a fourth gear. The driver includes a first case, a second case, a first driving motor, a second driving motor, and a power cable. The first case has a first chamber, a third chamber configured to accommodate the first driving motor, and a fourth chamber configured to accommodate the second driving motor. The second case has a second chamber. The first coupling post, the second coupling post, the first gear, the second gear and the third gear are accommodated in the first chamber. The third coupling post and the fourth gear are accommodated in the second chamber.
