The present disclosure provides a method for determining a presence of a relay in a pillow speaker, including sampling a voltage of a relay drive line to detect a first feedback state; providing a control signal to activate the relay drive line; sampling a voltage of the relay drive line during activation to detect a second feedback state; and comparing the first feedback state and the second feedback state to detect a presence of a relay. In another aspect, a pillow speaker relay circuit includes a relay drive line with a relay terminal configured to connect to a relay such that current flows through the relay when the relay drive line is activated; a control circuit operable to activate the relay drive line, and a feedback detection circuit configured to detect a voltage of the relay drive line; and a controller to perform any of the disclosed methods.

A neck pillow includes: a cushion portion worn on a user's neck and an electro-liquid driving unit mounted into the cushion portion, being bent in a shape of an arc, and including ferroelectric particles, each having an electrorheological property, and nonconductive liquid. The electro-liquid driving unit generates vibration by contraction and expansion that are repeated when an arrangement of the ferroelectric particles and the nonconductive liquid is changed according to whether drive current is applied. A low voltage power supply unit supplies low voltage electricity necessary to drive the electro-liquid driving unit and a high voltage control circuit unit converts low voltage direct current into high voltage direct current and supplies the drive current to the electro-liquid driving unit and adjusting micro-current to generate target vibration in the electro-liquid driving unit.

A folding pillow includes a top pillow section and a bottom pillow section. The top pillow section includes a first access opening, and a first internal pillow insert. The bottom pillow section includes a second access opening, and a second internal pillow insert. The folding pillow also includes a hinge section, where the folding pillow is configured to fold at the hinge section and have a folded position and an unfold position. The folding pillow also includes a sleeping panel, where the sleeping panel is covered when the folding pillow is in the folded position.

A combination digging tool and head rest is disclosed having a planar elongate linear member having a first end and a second end, and a planar non-linear member. The linear and non-linear members are coupleable to one another at different locations to form first and second orientations. The first orientation is formed when the first end of the planar elongate linear member is coupled to the first end of the non-linear member so that the planar elongate linear member and the planar elongate non-linear member are coplanar and form a generally J-shaped figure. That figure can be used as a digging tool. The second orientation is formed when the first end of the planar elongate linear member is coupled to the side portion of the non-linear member to form a head rest.

A wrinkle pillow, comprising two lobes each comprising a top, a bottom, and a side; a tapered indentation joining the two lobes, wherein the two lobes and the tapered indentation form an exterior comprising an hourglass shape, and further wherein the tapered indentation comprising a top, a bottom, and a side; and a filling.

The present disclosure relates to a method for determining a mouth leak status associated with a user of a respiratory device is disclosed. Airflow data associated with the user of the respiratory device is received. The respiratory device is configured to supply pressurized air to an airway of the user during a therapy session. The airflow data includes pressure data. The airflow data associated with the user is analyzed. Based at least in part on the analysis, the mouth leak status associated with the user is determined. The mouth leak status is indicative of whether or not air is leaking from a mouth of the user.

An infection control filter label includes a frame and a filter membrane that covers a window through the frame. The frame may be removably secured to a cover for an item, such as a cushion (e.g., a pillow, a positioner, a mattress topper, a mattress, a seat cushion, etc.), bedding (e.g., a duvet, etc.), or the like to provide a sealed cover for the item. The sealed cover may be impermeable, with the infection control filter label limiting the passage of dust and microorganisms (e.g., fungi, bacteria, mold spores, etc.) from passing therethrough. Thus, the sealed cover may protect its contents from external factors (e.g., sick individuals, etc.) while protecting the environment outside the sealed cover from the contents of the sealed cover. Information about the item may be provided on the frame; for example, by printing, writing, or the like.

A cover for a cushion includes a first panel, a second panel, and a primary receptacle defined between the first panel and the second panel. The primary receptacle may receive a primary cushioning element, such as a pillow, a pillow insert, or a fill material. At least one of the first panel and the second panel includes a secondary cushioning element. The secondary cushioning element may be defined from a compressible, resilient elastomeric material that defines a plurality of thin interconnected walls that in turn define an array of open cells or columns. Each cell or column may have a hexagonal shape, imparting the array of open cells or columns with a honeycomb appearance. Methods for assembling a primary cushioning element with such a cover are also disclosed.
