Methods and devices for reading a memory cell using multi-stage memory sensing are described. The memory cell may be coupled to a digit line after the digit line during a read operation. A transistor may be activated to couple an amplifier capacitor with the digit line during the read operation. The transistor may be deactivated for a portion of the read operation to isolate the amplifier capacitor from the digit line while the memory cell is coupled to the digit line. The transistor may be reactivated to recouple the amplifier capacitor to the digit line to help determine the value of the memory cell.

In many aspects, the systems and methods described herein include mattress assemblies with attached sensory devices. The mattress assembly comprises a mattress core, an attached headboard, a mattress cover at least partially enclosing the mattress core, and at least one customer assistance sensory device attached to at least one of the core, headboard, and cover. The customer assistance sensory device is configured to present at least one parameter of the mattress core or assembly as at least a visual signal. Visual signals may include one or more distinct colors, shapes, or graphic patterns that correspond to one or more parameter of the mattress core or assembly.

A cushioned knee separator for use by a person for placing between the person's legs when sleeping on one's side. The separator comprises an air-tight padding member and a securing member. The padding member comprises an envelope forming an air-tight enclosure, wherein the envelope comprises a pair of opposite surfaces; a membrane attached to the contacting faces and limiting relative movement of the contacting faces; filling material filling the enclosure; and a valve mounted to the envelope for controllably disrupting air tightness within the enclosure. The securing member is for securing the separator to one leg of the person. The separator is therefore adapted to maintain a distance between the person's legs thereby avoiding contacts between the knees when someone is sleeping in a side sleeping position.

A footrest stretching device used for a convertible sofa including a left-side component and a right-side component; the left-side component and the right-side component are each provided with identical parts as follows: a mounting side-plate, a third foot lever and a fourth foot lever, with one end of the third foot lever and one end of the fourth foot lever being rotatably connected to the mounting side-plate; the footrest stretching device includes a first footrest connector connected to the other end of the third foot lever, and a second footrest connector connected to the other end of the fourth foot lever; an outer footrest mounting member is connected to the other end of the first footrest connector; a middle footrest mounting member is connected to the other end of the second footrest connector; a third footrest connector is rotatably connected onto the second footrest connector; a fourth footrest connector is connected onto the third footrest connector; an inner footrest mounting member is rotatably connected to the other end of the fourth footrest connector.

A back rest assembly includes a base assembly mountable adjacent a resting surface and a back rest having a supported side pivotably supported by the base assembly and an unsupported side spaced laterally apart from the supported side along a lateral axis. When the base assembly is mounted, the back rest is positionable over the resting surface and selectively pivotable about the lateral axis for adjusting an angular position of the back rest relative to the resting surface.

Embodiments of an orthopedic pillow are provided for supporting the head of a sleeper in a supine position. In one embodiment, the orthopedic pillow includes a base having a centerline, a primary head support surface provided on the base, and laterally-opposed side rails extending upwardly from the base and flanking the primary head support surface. The laterally-opposed side rails include, in turn, interior portions and reinforcement portions. The interior portions are located adjacent the primary head support surface and each formed from a first material having a first stiffness, such as a molded foam having a first density. The reinforcement portions are located outboard of the interior portions, as taken along a lateral axis perpendicular to the centerline. The reinforcement portions formed from a second material having a second stiffness greater than the first stiffness, such as a molded foam having a second density greater than the density.

A sofa bed includes a mattress frame, a back frame, two arm frames and two cross beams, two arm frames are connected by the two cross beams, wherein the mattress frame and the back frame are rotatably pivoted. The inner side of the arm frame is disposed with a linking mechanism. The linking mechanism has a front connecting piece, rear connecting piece and a bridge connecting piece. Two ends of the bridge connecting piece are respectively pivoted to the front connecting piece and the rear connecting piece. The bottom end of the front connecting piece is pivoted to the arm frame. The bottom end of the rear connecting piece is pivoted to the arm frame. The linking mechanism has a front connecting piece, rear connecting piece and a bridge connecting piece.

Apparatus and methods for providing therapeutic treatment for symptoms associated with GERD and/or other digestive disorders and/or other medical conditions are described herein. In some embodiments, an apparatus includes a support element and a conformable riser element adjacent the support element. The riser element and the support element collectively form a body support member configured to support a user and define a receiving portion configured to receive a portion of the user's arm. The riser element and the support element are each disposed within a casing formed at least in part with a stretch material. In some embodiments, the riser element includes a polyester filler material and the stretch material includes a four-way stretch material. The four-way stretch material in combination with the polyester filler material enables the riser element to be conformable.
