  • Publication number: 20080163113
    Abstract: A method is described for user customized single screen order taking. The method saves users time to submit subsequent orders by storing their selection of items and having the system use that stored information to avoid selecting the desired items for each subsequent order. In practice, upon initial logon, a menu of items is presented to the user in response to the users inputted identification and password. The user can then select a subset of items from the displayed menu for the present and subsequent logons. A single data entry screen presenting the specific data entry needs for the selected items then is displayed on the present and subsequent logins. This ordering method also permits the user to save all data entered on a data entry screen in modified or unmodified format for submission at a subsequent time for fulfillment.

  • Patent number: 5599617
    Abstract: A conformable, nonslip article support pad has a flexible substrate formed of a resiliently compressible foam material and a flexible film bonded onto an upper surface of the foam substrate. The flexible film forms an upper surface on the article support pad that has a kinetic coefficient of friction with steel that is greater than 1.0 and, in cooperation with the substrate, forms a drapable structure having a readily deformable, slip-resistant, upper surface. The article support pad will maintain an article placed thereon at its initial position even though the surface of the support pad is tilted by as much as 78.degree. from a horizontal plane.
