  • Patent number: 6866340
    Abstract: A chair and standing device includes a mechanism for allowing movement in an individual's hips and lower back while seated in a chair or standing in one's workstation, by letting the pelvis glide unabated through an apparatus made up of a series of balls, round springs or magnets built into a two pad chair seat cushion. Two pads under the respective ilia of the person preferably move in a forward & rearward glide pitch, roll, yaw and opposing medial glide enhanced by a ΒΌ? to ?? raised platform in the center of the apparatus. The chair allows the pelvis to move in a gliding motion that mimics walking while the person is seated or standing, thus reducing the structurally caused lower back pain and stiffness so commonly associated with long periods of standing or sitting.

  • Publication number: 20020092085
    Abstract: A belt to be worn around the waist that contains microfilmed or reduced pages of the Bible on the surface of the belt. The reduced pages can be either applied to the surface of the belt or the microfilmed pages can be fitted into laminated grooves so that the film can be seen from the outside of the belt. The pages of the Bible can be photographically reduced onto paper, microfilm, plastic or metal and then can be adhered to the belt surface. A bracelet can also be fitted with the same reduced pages. A thick magnifying glass is fitted into the buckle in order to read the reduced pages.

  • Patent number: 6139095
    Abstract: A split-seat chair includes a mechanism for stimulation of a person's hips while seated in the chair, by generally simulating the hip motion which occurs during walking, or by allowing such movement by the user. Two platforms under the respective buttocks of the person preferably move in orbital motions about a horizontal axis transverse to the chair, the two pads orbiting 180.degree. out of phase relative to one another. The speed of orbital motion is preferably coordinated with the rate of circulation of cerebrospinal fluid in the skull as it travels down into the sacrum. The chair moves the pelvis in a gliding motion that partially mimics walking while the person is seated, thus reducing posturally caused lower back pain and stiffness.
