Patent number: 8636750Abstract: A device for removing hair is disclosed. The device comprises a container, filled with an impedance matching medium, and an ultrasound transducer element coupled to the container, such that ultrasound waves are generated by the transducer element in the impedance matching medium. The device further comprises a hair receiving element having at least one opening for receiving hair shafts, wherein a height of the opening is approximately an integer multiplication of half a wavelength of the ultrasound waves.Type: GrantFiled: August 27, 2009Date of Patent: January 28, 2014Assignee: Applisonix Ltd.Inventors: Nir Berzak, Abraham Dayan, Yuri Lechtzier, Assaf Guterman, Nir Rotem, Uri Amir, Alon Goren

Publication number: 20110224692Abstract: A device for applying vibrations to hair rooted in a body, includes: a pair of tongs having hair-gripping ends capable of being driven into high-frequency vibrations with respect to each other; and a transducer coupled to at least one of the tongs for converting an AC voltage to mechanical vibrations for driving the hair-gripping end into vibrations with respect to generate sufficient heat within the body to facilitate removal of the unwanted hair. The transducer is preferably a piezoelectric element which vibrates the hair at a frequency of 100-500 KHz, preferably 100-350 KHz, and produces a displacement of 5-20 microns.Type: ApplicationFiled: June 9, 2009Publication date: September 15, 2011Inventors: Alon Goren, Uri Amir, Assaf Guterman, Benjamin Geller, Valentina Melnikov, Ephraim Carleback, Abraham Dayan, Nir Berzak, Yuri Lechtzien, Nir Rotem

Patent number: 7993331Abstract: A method of treating unwanted hair is disclosed. The method comprises: transmitting acoustic waves through the hair so as to generate heat at a follicle, a dermal papilla, a hair bulge and/or a germinal matrix of the hair. The heat itself is sufficient to damage or destroy the follicle, the dermal papilla, the hair bulge and/or the germinal matrix.Type: GrantFiled: February 20, 2005Date of Patent: August 9, 2011Assignee: Applisonix Ltd.Inventors: Amir Barzilay, Alon Goren, Abraham Dayan, Vladimir Furman, Assaf Guterman, Yehuda Niv

Publication number: 20060052661Abstract: In therapeutic endoscopy micro-knives, electrical diathermy or laser beam replace the conventional hand-held scalpel. The laser “knife” has substantial capabilities over the rest: it can cut incisions, coagulate hemorrhages and ablate (vaporize) neoplastic tissues, while interaction is contact-less and sterile. The laser energy is delivered transendoscopically through rigid or flexible fiberoptic waveguides. Flexible endoscopes are used to access body curved spaces and cavities, such as the digestive tract. A control system for minimally invasive surgery, and more particularly, for laser surgery using infrared laser is provided. A feedback mechanism is provided to obtain thermographic information from the targeted site and a processor uses this thermographic information to monitor and control input parameters, including air flow, suction, and laser beam parameters.Type: ApplicationFiled: January 22, 2004Publication date: March 9, 2006Applicant: Ramot At Tel Aviv University Ltd.Inventors: Israel Gannot, Alon Goren, Abraham Dayan

Patent number: 4819437Abstract: A method is provided for converting sensible heat energy of a heating fluid supplied by a high-temperature heat source to work, by means of a thermodynamic cycle employing a multi-component working fluid, wherein a "rich solution" having a higher concentration of lower boiling component, or components, is heated in a vapor generator in counter-current heat exchange with the heating fluid to produce a vapor-liquid mixture which is introduced into a lower zone of a rectifier and separated therein into a "lean solution" having a higher concentration of said lower boiling component, or components, and a vapor mixture; the enthalpy of the vapor mixture is increased by passing it through a superheater in counter-current heat exchange with said heating fluid at its highest temperature; the vapor mixture is then expanded in a first turbine to an intermediate pressure level thereby to generate work and subsequently in a second turbine to a low pressure level to generate additional work; the spent vapor mixture is thenType: GrantFiled: May 27, 1988Date of Patent: April 11, 1989Inventor: Abraham Dayan
