Methods and apparatus are disclosed for applying acoustic energy to the skin. Acoustic waveguides with elements of varying thickness or shape are disclosed which deliver energy to more than one depth below a surface of the skin substantially simultaneously. The invention is especially useful with devices that focus ultrasound energy by condensing a propagating wavefront. The invention compensates for the mismatch in acoustic properties of the device's waveguide and the biological tissue that typically cause portions of the collapsing wavefront to lag behind other portions and, thereby, limit the focusing capabilities of acoustic treatment devices.

PCT No. PCT/EP96/05140 Sec. 371 Date Apr. 23, 1998 Sec. 102(e) Date Apr. 23, 1998 PCT Filed Nov. 21, 1996 PCT Pub. No. WO97/19206 PCT Pub. Date May 29, 1997The invention relates to a method for the electrolytic deposition of metal coatings, in particular of copper coatings with certain physical-mechanical and optical properties and uniform coating thickness. According to known methods using soluble anodes and applying direct current, only uneven metal distribution can be attained on complex shaped workpieces. By using a pulse current or pulse voltage method, the problem of the coatings being of varying thickness at various places on the workpiece surfaces can indeed be reduced. However, the further problem of the geometric ratios being changed continuously during the depositing process by dissolving of the anodes is not resolved thus. This can be avoided by using insoluble anodes. In order to guarantee sufficient stability of the anodes and a bright coating even at those points on the workpiece surfaces, onto which the metal is deposited with high current density, it is essential to add compounds of an electrochemically reversible redox system to the depositing solution.

A cleaning and whitening system for teeth having an electromagnetic radiation emitting toothbrush and a dentifrice with a photosensitive agent is disclosed. The toothbrush has a cleaning surface, such as bristles. The toothbrush is also adapted to direct electromagnetic radiation toward the cleaning surface. The electromagnetic radiation may be monochromatic or polychromatic. Further, the electromagnetic radiation may be substantially free of ultraviolet radiation. Additionally, the electromagnetic radiation may consist essentially of wavelengths within a range of 300 to 750 nanometers. The photosensitive agent is dispersed throughout the dentifrice. The dentifrice transmits the electromagnetic radiation through a varying thickness disposed over a target surface during use of the system. As a result, a significant portion of the photosensitive agent reacts, resulting in whitening stains, removing and/or disclosing undesired substances, and/or foaming. The dentifrice may be clear and may have clear abrasive particles. A method for tuning the cleaning and whitening system for teeth includes formulating the dentifrice with photosensitive agents that react to a range of electromagnetic radiation and providing a toothbrush that emits that electromagnetic radiation range. Another method of tuning the cleaning and whitening system includes designing a toothbrush that emits a range of electromagnetic radiation and formulating a dentifrice with photosensitive agents that react to the electromagnetic radiation range.

The invention provides a class of samples that model the human body. This family of samples is based upon emulsions of oil in water with lecithin acting as the emulsifier. These solutions that have varying particle sizes may be spiked with basis set components (albumin, urea and glucose) to simulate skin tissues further. The family of samples is such that other organic compounds such as collagen, elastin, globulin and bilirubin may be added, as can salts such as Na+, K+ and Cl-. Layers of varying thickness with known index of refraction and particle size distributions may be generated using simple crosslinking reagents, such as collagen (gelatin). The resulting samples are flexible in each analyte's concentration and match the skin layers of the body in terms of the samples reduced scattering and absorption coefficients, mums and muma. This family of samples is provided for use in the medical field where lasers and spectroscopy based analyzers are used in treatment of the body. In particular, knowledge may be gained on net analyte signal, photon depth of penetration, photon radial diffusion, photon interaction between tissue layers, photon density (all as a function of frequency) and on instrument parameter specifications such as resolution and required dynamic range (A/D bits required). In particular, applications to delineate such parameters have been developed for the application of noninvasive glucose determination in the near-IR region from 700 to 2500 nm with an emphasis on the region 1000 to 2500 nm (10,000 to 4,000 cm-1).
