  • Patent number: 7278960
    Abstract: A method of exercising in which selected muscle tissue contacts against externally applied pressure. A user places an object, or member, in contact with a body part, and applies pressure to the member, which is transmitted through the body-contacting surface of the member to the underlying muscle tissue. The pressure provides resistance to muscle expansion as occurs during a muscle contraction. A plurality of body-contacting surfaces is provided, each having different dimensions, which will allow a user to alter the pattern in which pressure is transmitted to the underlying tissue. This will allow a user to select an appropriate body-contacting surface to develop specific portions of muscle, rather than muscles as a whole. Pressure can be applied to the member in various ways, such as by manual force or with the use of a strap that is wrapped around the member and the body part being exercised.

  • Patent number: 6764190
    Abstract: The present invention includes an illuminated sign display assembly comprising: a transparent panel having two oppositely facing planar surfaces separated by a surface forming a linear edge between said oppositely faced surfaces, one of said oppositely facing surfaces adapted to support a sign; a light source on or adjacent to said linear edge for transmitting light between said opposite facing surfaces; characterised in that at least one of said oppositely facing surfaces has applied thereon at least one single continuous line forming a matrix extending substantially over the entire surface of said at least one of said oppositely facing surfaces. The applicants have found that the sign display assembly of the present invention enables even distribution of transmitted light and effectively illuminates the entire panel even at distances remote from the light source.
