The invention relates to a method for using a cushion, in particular for a chair, said cushion having a first cushion element (6) that can be moved with an associated degree of freedom. In said method, a sensor (98a, 98b, 98c, 98d) integrated into the cushion is used to sense the position or the change in position relative to at least one first cushion element (6), with respect to at least one degree of freedom associated with said element. The sensor (98a, 38b, 98c, 98d) is coupled to an interface (93) for the wireless output of measured values. The sensor (98a, 98b, 98c, 98d) senses measured values and sends at least some of the measured values over the interface (93) to a device (70, 80) outside the cushion, said device (70, 80) receiving and evaluating the measured values and emitting an output signal.

A method of remanufacturing a toner cartridge includes installing a modified end cap in which a portion of a drive assembly for an internal toner seal removal mechanism has been disabled. With the modified end cap installed, the toner cartridge may be post tested without removing the internal toner seal. When the post test is complete the modified end cap is removed and a non-modified end cap with a functional drive assembly is installed in its place.

An apparatus for improving blood flow in a user's leg and improving posture is disclosed herein. The apparatus is a portable seating cushion that a user may sit upon, which improves blood flow by reducing point-pressure that may otherwise be applied to nerves and blood vessels in a user's leg, including the sciatic nerve. Moreover, the portable seating cushion improves posture by creating a forward pelvic tilt, which causes the rest of the user's shoulders, spine, back, and neck to come into alignment when the user sits on the cushion.

A portable chair; the portable chair includes a seat-panel, a first side panel, a second side panel, a rear panel, and a front panel. The portable chair is insertable into a shopping cart seat or a highchair or other public seating. And is designed for use by infants or small children. The portable chair provides a soft collapsible child seat insert for shopping carts and highchairs designed to offer additional comfort and support for an infant.

A ventilation mat according to the present invention is a ventilation mat including: a ventilation mat body including a plurality of tubes coupled to one another in a sheet shape; and a ventilation guide connected to a side surface of the ventilation mat body, in which the ventilation mat body includes: a ventilation part with a slit provided on a side of the plurality of tubes coming into contact with the skin cover so as to be extended across the plurality of tubes, the ventilation part being coupled, with a material of the tube, to a side of the plurality of tubes coming into contact with the sheet cushioning material; and an air flow mixing part that is provided closer to a connection part of the ventilation guide than the ventilation part is, and communicates between the plurality of tubes.

Embodiments of the invention relate to a cushion apparatus comprising a resilient spring member. Typically, the cushion apparatus in configured to provide flexible support to a user, allow air circulation through and within the cushion apparatus and allow ventilation of excess heat. In some embodiments, the cushion apparatus comprises a resilient spring member and a cushion cover member at least partially enclosing the spring member. In some embodiments, the cushion cover member is structured to be removable attached to the resilient spring member.

A pneumatically adjustable bladder system (90) for use in a cushioned seat bottom (24) has one or two rear foam filled bladders (62, 64) for location under the ischial tuberosities of a seated occupant of the seat bottom, and one or more expansion chambers (14, 16) or front foam filled bladders (66, 68) for location under the thighs of the seated occupant. There are air passageways (70, 72, 74, 92) interconnecting the bladders with each other or with an expansion chamber. The system is air tight and the bladders are compressible under the weight of the seated occupant and are expandable when the weight is removed. The compression of a bladder causes air therewith in to be displaced through the air passageways to the expansion chambers or to the other bladders, which then expand. The compression of a bladder under the ischial tuberosities of the seated occupant and the expansion of the expansion chambers or of the other bladders under the thighs of the seated occupant cause the seated occupant to experience a correct level of immersion into the cushioned seat bottom which is desired for effective postural support and prevention of lower back pain.

The present disclosure relates to a breathable cushion. The cushion includes a thigh support portion, a hip support portion, and a waist and back support portion. The thigh support portion includes a plurality of thigh support structures each having an opening structure; the hip support portion includes a plurality of hip support structures each having an opening structure; and the waist and back support portion includes a plurality of waist and back support structures each having an opening structure. The area of the opening structures of the thigh support structures and/or the area of the opening structures of the waist and back support structures is greater than the area of the opening structures of the hip support structures. The cushion has the following advantages. The cushion has an ergonomic design and structure, and provides reasonable and reliable supports. In addition, the light-weight and highly comfortable cushion has good air permeability.

An inflatable seat cushion apparatus for comfort and pain prevention includes a cushion bladder having a bladder front side, a bladder back side, a bladder top side, a bladder bottom side, a bladder left side, and a bladder right side defining a bladder inside. A pump is coupled to the cushion bladder. The pump is coupled to the bladder left side within the bladder inside and has an intake vent and a power switch extending through the bladder left side. The power switch activates the pump to inflate the bladder inside. A release valve is coupled to the cushion bladder and extends through the bladder left side to selectively deflate the bladder inside. A pair of foam wings is coupled to the cushion bladder. The pair of foam wings is coupled to the bladder top side adjacent the bladder left side and the bladder right side.
