Patent number: 8943705Abstract: A method for heating an object having a variable weight that includes a medium is provided. The method comprises: (A) placing the object having the variable weight including medium into an enclosure; (B) initiating a heating process by subjecting medium including the object having the variable weight to a variable AC electrical field; and (C) controlling the heating process. The object has substantially absorbed medium in a first “cool” state and therefore includes a maximum weight in the first “cool” state due to absorption of medium. The object is substantially free from medium in a second “heated” state due to substantial release of medium from the object, wherein the released medium is evaporated during the heating process. The heating process is completed when the object is substantially transitioned into the second “heated” state. The method further comprises using an air flow having an ambient temperature inside the enclosure to carry away the evaporated medium from the enclosure.Type: GrantFiled: May 20, 2011Date of Patent: February 3, 2015Assignee: Cool Dry LLCInventors: David S. Wisherd, John A. Eisenberg, Pablo E. D'Anna

Publication number: 20140325865Abstract: Methods and apparatus for heating an object 9 that includes an absorbed medium. A method embodiment comprises: placing the object 9 including the medium into an enclosure 16; initiating a heating process by subjecting the object 9 and medium to a capacitive AC electrical field generated by an RF power source 2 at a single low frequency; controlling the heating process by taking real time measurements; and making real time adjustments to the RF power source 2 in response to the real time measurements. The object 9 substantially absorbs the medium in a first “cool” state, and therefore has a maximum weight in the first “cool” state. The object 9 is substantially free from the medium in a second “heated” state, due to substantial release of the medium from the object 9. The released medium is evaporated during the heating process. The heating process is completed when the object 9 is substantially transitioned into the second “heated” state.Type: ApplicationFiled: July 21, 2014Publication date: November 6, 2014Applicant: Cool Dry LLCInventors: David S.

Patent number: 8826561Abstract: A method for heating a medium that includes an object having a variable weight is provided. The method comprises (A) placing medium including an object having variable weight into a variable enclosure having adjustable dimensions; (B) initiating a heating process by subjecting the medium including the object to a variable AC electrical field; (C) substantially continuously measuring an impedance of medium including the object during the heating process; (D) adjusting dimensions of said variable enclosure to optimize the heating process; (E) adjusting parameters of the variable AC electrical field to optimize the heating process; and (F) controlling the heating process.Type: GrantFiled: June 17, 2010Date of Patent: September 9, 2014Assignee: Cool Dry LLCInventors: David S. Wisherd, John A. Eisenberg, Pablo E. D'Anna

Publication number: 20130119055Abstract: A method for RF dielectric heating an object having a variable weight including a medium is provided The method comprises: (A) placing the object having the variable weight including the medium into an enclosure; (B) adding an ionic substance to the medium; (C) initiating a heating process by subjecting the medium including the object to a variable AC electrical field; and (D) controlling the heating process. The method further comprises using an air flow having an ambient temperature, or being heated before getting into the enclosure, to carry away the evaporated medium from the enclosure.Type: ApplicationFiled: November 16, 2011Publication date: May 16, 2013Applicant: COOL DRY LLCInventors: Michael Andrew Wohl, David S. Wisherd, John A. Eisenberg, Pablo E. D'Anna
