Abstract: A method for scaling and converting sounding data into physical properties of a scanned medium is disclosed. In one embodiment, sounding data is received and transformed into phase space, where the phase space transformation linearizes the sounding data. The slope and intercept of the phase space data is determined and then converted into physical parameters. The physical parameters are then returned. In a more specific embodiment, the critical frequency is returned for an ionogram.

Abstract: A method for determining usability of a cover material as a cover of a vehicle seat component includes determining a fabric stretch requirement for the vehicle seat component; determining actual fabric stretch of the cover material; and comparing the actual fabric stretch with the fabric stretch requirement to determine whether the cover material is satisfactory for use with the vehicle seat component as the cover.

Abstract: A method for selecting a cover material for use with a vehicle seat component includes establishing a material processability standard for cover materials selected from the group consisting of standards for marking resistance, fabric pattern, pile bind, rippling resistance, laminate wrinkle resistance, raveling resistance, seam puckering, stretch, and elongation; conducting testing of a cover material for compliance with the material processability standard to determine whether the cover material meets requirements of the material processability standard; and considering test results of the cover material before proceeding to utilize the cover material in manufacturing of the vehicle seat component.

Abstract: A handle attachment for a bowling ball includes a hand grip, a shank extending from the grip and a radially expansible plug extending from the shank. A mechanism for changing the length and therefore the radius of the plug between a locking position and a release position is controllable at the grip in a way that locks the mechanism in the locking position when the grip is grasped by the hand as in carrying a bowling ball. In the release position, the plug is inserted into and withdrawn from the thumb hole of the ball, and in the locking position the plug securely engages the sidewall defining the thumb hole thereby attaching the handle attachment securely to the bowling ball.
