Publication number: 20070164018Abstract: Dielectric welding apparatus has opposed electrodes that can be engaged on either side of a product to be welded and a dielectric welding power supply that supplies welding potentials to the electrodes. The apparatus includes electrically insulating buffer material adjacent to at least one of the electrodes. A recess formed in a surface of the buffer material receives an end of an electrically-conductive member in the product. The buffer material prevents arcing between the electrodes and the electrically-conductive member.Type: ApplicationFiled: March 13, 2007Publication date: July 19, 2007Applicant: COOLHEAD TECHNOLOGIES, INC.Inventors: R. FLETCHER, Christopher CLARKE

Publication number: 20060191675Abstract: A flexible heat exchanger is suitable for heating or cooling living subjects or objects. The heat exchanger has a volume having at least one inlet for receiving a heat exchange fluid and at least one outlet. A flexible heat exchange plate that is essentially impermeable to the heat exchange fluid is penetrated by substantially rigid thermally-conductive members. The members provide paths of high thermal conductivity through the plate. The heat exchange fluid may be water.Type: ApplicationFiled: March 21, 2006Publication date: August 31, 2006Applicant: Coolhead Technologies, Inc.Inventors: R.

Publication number: 20050061473Abstract: A heat exchanger for heating or cooling objects is flexible and can conform to surface profiles of objects to be warmed or cooled. The heat exchanger has a volume having at least one inlet for receiving a heat exchange fluid and at least one outlet. A flexible plate essentially impermeable to the heat exchange fluid is penetrated by substantially rigid thermally conductive members. The members provide paths of high thermal conductivity through the plate. The heat exchange fluid may be water based.Type: ApplicationFiled: September 22, 2003Publication date: March 24, 2005Applicant: Coolhead Technologies, Inc.Inventors: R. Fletcher, Yunquan Chen
