Abstract: A foam seating article includes an outer layer of molded foam surrounding a solid inner core of molded foam or expanded polystyrene. The rigid foam of the inner core is made from polyurethane polyol and methylene diphenyl diisocyanate (MDI). The inner core has a hardness greater than 25 Shore A and a density less than two pounds per cubic foot. The polymer material of the solid core has a hardness that is greater than that of the outer foam. The outer layer of molded foam is high density (HD) foam, memory foam or latex foam. A fabric covering encloses the inner core and molded outer foam layer. The foam seating article can be a chair, stool, sofa, chaise lounge, bench or Ottoman. The seating article includes no wood or metal. Molding foam around a solid inner core is simpler and less costly than making conventional metal or wood framed furniture.

Abstract: A foam seating article includes a layer of molded foam surrounding a hollow shell made of hard plastic. A fabric covering encloses the shell and molded foam. The foam seating article can take the form of a chair, stool, sofa, chaise lounge, bench or Ottoman. The hollow shell can be formed using blow molding, injection molding or by capping both ends of a tube with disks. Air pressure inside the airtight hollow shell prevents the shell from collapsing inwards under the weight of an occupant. Alternatively, the hollow shell of the seating article can be accessed through a removable lid. The seating article includes no wood or metal. The layer of molded foam includes sections of different foam types, such as high density (HD) foam, memory foam and latex foam. Molding foam around a hard plastic shell is simpler and less costly than making conventional metal or wood framed furniture.

Abstract: A compact collapsible chair includes upper tubes, leg tubes, a central tube connector and a seat back. The upper tubes are formed from detachable sections. Lower ends of the upper tubes are inserted into upper holes in the central tube connector, and upper ends of the leg tubes are inserted into lower holes in the central tube connector. Upper ends of the upper tubes fit into tube receptacles in the seat back. No part of the upper tubes other than the upper and lower ends contacts any part of the collapsible chair. The upper holes are disposed in an upper portion of the central tube connector that swivels over a lower portion into which the lower holes are bored. The upper portion and the attached upper tubes swivel about a cylinder that passes through the upper and lower portions but does not extend above or below the central tube connector.

Abstract: A collapsible beach chair includes upper tubes, leg tubes, a central tube connector, a seat back and a fabric support base. Lower ends of the upper tubes fit into upper holes in the tube connector, and upper ends of the leg tubes fit into lower holes in the tube connector. Upper ends of the upper tubes fit into first tube receptacles in the seat back, and ground ends of the leg tubes bit into second tube receptacles in the support base. The upper holes are disposed in an upper portion of the tube connector that swivels over a lower portion into which the lower holes are bored. The upper portion and the attached upper tubes swivel about a shaft that passes through the upper and lower portions but does not extend above or below the tube connector. The fabric support base prevents the leg tubes from sinking into the sand.

Abstract: A physiological sensor apparatus comprises a physiological sensor, a headband and an eye mask. In one example, the physiological sensor includes a plurality of electroencephalography (EEG) electrodes that are used to sense a signal indicative of a sleep stage (e.g., REM sleep or non-REM sleep) of a user. Each end of the headband attaches to respective ends of the sensor and eye mask such that when the sensor is disposed on the forehead of the user, the eye mask shields the eyes of the user from visible light. The diameter of the headband is adjustable by the user to secure the sensor to the forehead of the user. The sensor accurately determines the sleep stages of the user over a period of sleep of the user because the adjustable headband and eye mask prevent the electrodes from being displaced from the forehead of the user during the period of sleep.

Abstract: A method of making foam imparts antimicrobial and antiodorant qualities to the foam. Green tea powder is added to the polyol raw materials for making memory foam. The green tea memory foam is used to make pillows, cushions and mattresses. Green tea foam in the top layer of a mattress acts as an antiodorant such that less of the chemical smell of the memory foam is perceived by the user. In addition, the bacteria and mold that would otherwise develop in the moist warmer sleeping environment on memory foam are killed by the green tea additive to the foam. Measurable antimicrobial and antiodorant qualities in the green tea foam are achievable by adding green tea powder constituting less than 2% of the weight of the resulting green tea foam. A neck-support contour pillow is made using memory foam that contains green tea and a green dye.

Abstract: A process for the production of animal feed additives from fermentation broth containing L-lysine is disclosed. The process does not require filtering of biomass in order to remove the biomass and produces granulated lysine of controllable lysine content with a high bulk density, low viscosity, and a low hygroscopic property which does not require the addition of an anti-absorptive substance. In this process, a lysine fermentation broth produced after slant culture, flask culture, seed process, and cultivation process is concentrated to a solid content of about 44˜52%. A product with low hygroscopicity, high bulk density, and the intended amount of contents is produced after being mixed with substances for controlling the amount of contents and granulated by coating the surface of the seeds. This process enables a production of animal feed additives having a lysine-HCl content of at least 65%, a water content of at most 3%, and a bulk density of 670±50 kg/m3.

Abstract: An adjustable mattress that incorporates a movement mechanism and support member inside of the foam mattress includes a fabric covering with a fastener member. The fastener member is used to keep a fitted sheet in place over the adjustable mattress when the mattress is adjusted to an inclined configuration. The fastener member is attached to the fabric covering near the lower edge of the adjustable mattress and is adapted to fasten to a corresponding fastener on the fitted sheet. The fastener member can be a toggle that fits through a loop on the fitted sheet. The fitted sheet also has an elastic band that draws the fitted sheet taut around the adjustable mattress. The lower portion of the fabric covering is made of stretchable fabric that stretches between the lower edge of the adjustable mattress and a balancing bar that supports the adjustable mattress when the adjustable mattress is inclined.

Abstract: An infant mattress fits safely in a crib without any gap between the mattress and the walls or bars of the crib. A ring of memory foam surrounds the supporting foam layers of the mattress and forms a snug fit with the vertical bars of the crib regardless of whether the dimensions of the particular crib or mattress vary from their standard sizes. The memory foam ring intentionally renders the infant mattress somewhat larger than the inner dimensions of the crib. The ring compresses when the mattress is placed in a crib in which opposing side bars are separated by a distance that is smaller than the mattress width. The ring is formed by pouring foam into a rectangular mold around the supporting foam layers. Where the mattress includes pocket coils on the supporting foam layers, the ring of memory foam conforms to the outer row of pocket coils.

Abstract: A method for providing contents and an electronic device having a function therefore is disclosed. The method comprises receiving information regarding a current heart rate of a user, selecting an audio file having a specific tempo determined in consideration of the current heart rate and a reference heart rate, and reproducing the selected audio file and a heartbeat sound reflecting the current heart rate simultaneously. Therefore, the heartbeat of the user may be effectively controlled.

Abstract: A folding mattress support system replaces both a conventional box spring and the bed frame with rails. The mattress support system is lighter, quieter and easier to transport, and also provides more storage space beneath the mattress. The mattress support system includes bed frame assemblies, central connecting bars, edge attachments and a bed skirt. Leg brackets fold out from the bed frame assemblies, which themselves unfold in the middle. Central connecting bars connect inner side edges of the bed frame assemblies. Plastic edge attachments are attached at outer corners of the bed frame assemblies and hold a bed skirt taught around the frame assemblies when the frame assemblies are standing on the extended leg brackets. A mattress is then placed on top of the assembled mattress support system. Optionally, metal edge attachments at the head corners of the mattress support system both hold the bed skirt and support a headboard.
