Abstract: A spa cover lifter for moving a spa cover from a closed position to a storage position includes a drive mechanism, a fixed base and a lifting arm assembly. The lifting arm assembly is mounted to first or second leaves of the spa cover. The lifting arm assembly is driven by the drive mechanism and is moveably mounted to the fixed base. The lifting arm assembly includes a cover pivoting assembly and a cover transporting assembly. The cover pivoting assembly is driven by the drive mechanism to move the cover from the closed position to an intermediate position and the cover transporting assembly is driven by the drive mechanism to the move the cover from the intermediate position to the storage position. The spa cover lifter has an automatic shutoff for cutting power when an obstacle is encountered. A method of moving the spa cover is also disclosed.

Abstract: Portable medical oxygen concentrator comprising an air separation system adapted to recover oxygen from air; a bottom platform and a shell having an outer wall, wherein the shell is detachably connected to the bottom platform, wherein the shell and bottom platform define an enclosed volume when the shell is connected to the bottom platform, and wherein the air separation system is disposed in the enclosed volume; and one or more rechargeable batteries detachably connected to the outer wall of the shell and adapted to provide power to drive the air separation system. The air separation system may comprises a pressure swing adsorption system having two or more adsorbent columns and a rotary valve for directing gas flow sequentially to, from, and among the columns. A base assembly attached to the bottom platform may be adapted to support the two or more adsorbent columns and the rotary valve.

Abstract: A child activity device for entertaining and promoting activity in a child is disclosed. The child activity device is configurable between a use and storage position and may also include a frame providing bouncing motion for a child. The activity device includes a support frame extending vertically upwards from a lower end proximate to a support surface and terminating at an upper end, a supporting portion, and may further include a seat, coupled to the supporting portion, that is rotatable about a first axis relative to the support frame to allow a child placed in the seat to rotate about the first axis. A coupling assembly is also disclosed. The coupling assembly secures the supporting portion to the support frame upper end and permits rotation of the supporting portion about a second axis for configuring the seat and supporting portion in a storage position. An activity device with foldable support legs is also disclosed.

Abstract: An infant soothing device includes a base, a rocking platform pivotally mounted to the base, a drive mechanism for reciprocating the rocking platform up and down relative to the base and a carriage having an infant restraining device positioned thereon, the carriage shaped to reciprocably move back and forth within the rocking platform.
