Banded papers, smoking articles and methods
Patent No. 8,925,556
Wrapper for cigarette manufacture includes transversely extending band regions applied by a printing technique, such as gravure printing. The band regions comprise starch, an anti-wrinkling agent such as 1,2 propylene glycol or glycerin, and optionally calcium carbonate.

Patent No. 8,928,887
Methods mapping a characteristic parameter of a specimen, such as a scattering mean free path and a scattering anisotropy factor, based on a quantitative phase shift measurement. The methods have steps of using spatial light interference microscopy (SLIM) to determine a quantitative phase shift as a function of position in a sample, and applying a generalized scatter-phase transformation to derive at least one of a scattering mean free path (MFP), a scattering anisotropy factor, and a thickness-independent parameter as a function of position in the sample. In some cases, the sample may be a slice of tissue or a cell.

Sports ball training assembly
Patent No. 8,932,155
A sports ball training assembly for repetitively practicing sporting techniques in a small area, such as, hitting a golf ball, kicking a soccer ball, or batting a baseball. A telescoping arm attaches to the ball, extending and retracting to create different positions to strike the ball. A spring attaches to the telescoping arm. The spring has sufficient elasticity to return the ball to equilibrium position after the ball is propelled forward. The elasticity of the spring and the elevation of the ball can be adjusted by enclosing various sections of the spring with a tube that slides along the longitudinal axis of the spring. As the rigid tube moves along the spring, the spring’s characteristics change. A second spring portion enhances stability and control of the ball, and allows the ball to return to the user. A base and a base shaft provide structure to the assembly.
