Filed:

May 15, 2000

Appl. No.:

09/570909

Inventors:

Yu Chen - Baltimore MD, US
Ming An Chen - Baltimore MD, US

International Classification:

A61B 17/00

US Classification:

606204

Abstract:

A method and device for the treatment of anxiety disorder, including panic attacks. A hammer is used to tap the cutaneous region of the bladder channel on the back until the skin turns pink. The skin on the abdomen, arms, legs, and buttocks can also be used for treatment. The hammer preferably has a magnetic piece in one end of the hammer head. The method can treat anxiety disorder including panic attack, general anxiety, phobia, posttraumatic stress disorder, stress related tension headache, insomnia, and any stress. Patients can use the hammer to treat themselves at home, office, and during traveling. The method and device are simple, effective, nontoxic, safe, have no side effects, inexpensive, and convenient.

B05D 5/08

Abstract:

The present invention relates to techniques for lowering friction between moving surfaces of, for example, an internal combustion engine. Friction reduction is achieved by adding texture modifications to surfaces that come in contact with each other. Texture modifications that reduce friction in accordance with the present invention include dimples of varying geometries and depths ion the surfaces of components. The present invention also relates to the lubrication technique for applying the texture to the surfaces. In another embodiment, the patterned soft mask is applied onto a large surface (flat or curved including cylindrical rollers surfaces) to be followed by electrochemical etching to imprint the textures onto the component And, in another embodiment, a diamond-like-carbon (DLC) film may be applied to the turbine component to also reduce friction.
