Patent number: 6583368Abstract: The invention—Ayurvedic Scale—is a machine that physically represents or models the philosophical essence of the ancient science and philosophy of Ayurveda in the form of a tri-armed scale. The Ayurvedic Scale's primary function is to assist users in determining and visually representing their current spiritual state as well as their underlying Ayurvedic body type, which are both helpful in evaluating immediate choices using Ayurvedic philosophy. It also serves to act as a visual model in helping users to more clearly understand the complexities of Ayurveda, to provide a physical reminder of Ayurveda's suggested foci in the user's life, and to act as a decorative model, which reflects the owner's interest in Ayurveda. The invention is meant to embody two of Ayurveda's core foci—simplicity and balance.Type: GrantFiled: March 27, 2001Date of Patent: June 24, 2003Inventor: Daniel K Pivinski

Patent number: 6509534Abstract: A lightweight, portable scale, including a balance beam pivotally positioned on a fulcrum, contained in a tear-drop shaped carrying case. The portable scale has a load pan on one end of the balance beam and a graduated scale, configured to accommodate sliding weight members, extending toward the opposite end of the balance beam. The fulcrum is positioned between the load pan and the graduated scale. To establish equilibrium, the balance beam includes a stationary counter-weight attached on the load pan side of the fulcrum, which balances the empty load pan against the sliding weight members located at a zero position on the graduated scale. The carrying case has a top portion hingedly attached to a bottom portion, which functions as the base of the portable scale and has sidewalls shorter than the fulcrum, preventing interference by the side walls during the weighing process.Type: GrantFiled: November 20, 2000Date of Patent: January 21, 2003Inventor: Mohan Thadani
