Publication number: 20120200304Abstract: A method for use in determining the thickness of a layer of interest in a multi-layer structure. A first electrode is positioned in contact with a first surface of the multi-layer structure, and a second electrode is positioned in contact with a second surface of the multi-layer structure. The second surface is substantially opposite the first surface. The first electrode is pressed against the multi-layer structure at a predetermined sampling pressure, and the structure is optionally adjusted to a predetermined sampling temperature. The electrical impedance between the first electrode and the second electrode is measured.Type: ApplicationFiled: February 4, 2011Publication date: August 9, 2012Inventors: Atanu Saha, Krishnamurthy Anand, Hari Nadathur Seshadri, Karthick Vilapakkam Gourishankar, Filippo Cappuccini

Publication number: 20120199576Abstract: A low resistance electric heating system comprising a low resistance electric conducting material being formed into an electric heating element 10 in two flat spiraled sections 10a and 10b covering almost all the area to be heated, comprising a low resistance electric conducting material with sufficient resistance to generate heat. The flat spiraled sections 10a and 10b of the electric heating element 10 are spirally configured, so that the heat generating current flows in the same direction and not in opposition in each of the flat spiraled sections 10a and 10b. The centre 10c of each of the flat spiraled sections 10a and 10b of the electric heating element 10 are electrically connected to each other in series. The flat spiraled sections 10a and 10b are connected to the controlled power supply 11 at the outer part of the flat spiral 10d, completing the circuit.Type: ApplicationFiled: July 1, 2010Publication date: August 9, 2012Inventor: Paul Lenworth Mantock

Patent number: 8217308Abstract: A more comfortable seat is provided by detecting whether or not a person is in a seat. A seat has a heating element 1, a seat surface temperature detector 5 that is situated below a seat surface cover and that detects the temperature of the seat surface, and a seating determination unit 6 for determining whether or not a seat is occupied. A determination is made as to whether or not a seat is occupied according to an amount of temperature change detected by the seat surface temperature detector 5 for a predetermined period of time, whereby a determination can be readily made as to whether or not a person is seated. When no one is seated, application of power to the heating element 1 is stopped, and the like, which in turn contributes to energy saving and enhancement of fuel efficiency.Type: GrantFiled: April 17, 2008Date of Patent: July 10, 2012Assignee: Panasonic CorporationInventors: Naohito Asami, Masanori Nishikawa
