Patent number: 6809303Abstract: Devices and methods for applying heat to a platen of a biometric image capturing device are described that remove and prevent the formation of excess moisture on the platen. These devices and methods prevent undesirable interruptions of total internal reflection of a prism that result in biometric images having a halo effect. In embodiments of the invention, an electrically conductive transparent material is used to apply heat to the platen. In other embodiments, resistive heating elements attached to non-optical areas of the platen (e.g., the ends) are used to apply heat to the platen. Heater assemblies according to the invention can be used to heat an area where a biometric object is placed, or an area adjacent to where the biometric object is placed, to remove and prevent the formation of excess moisture on the platen.Type: GrantFiled: January 17, 2002Date of Patent: October 26, 2004Assignee: Cross Match Technologies, Inc.Inventors: John F. Carver, George W. McClurg, Joe F. Arnold

Patent number: 6806443Abstract: Ceramic susceptor whose wafer-retaining face has superior isothermal properties, and that is suited to utilization in apparatuses for manufacturing semiconductors and in liquid-crystal manufacturing apparatuses. In plate-shaped sintered ceramic body 1, resistive heating element 2 is formed. Fluctuation in pullback length L between sintered ceramic body outer-peripheral edge 1a and resistive heating element substantive-domain outer-peripheral edge 2a is within ±0.8%, while isothermal rating of the entire surface of the wafer-retaining face is ±1.0% or less. Preferable is a superior isothermal rating of ±0.5% or less that can be achieved by bringing the fluctuation in pullback length L to within ±0.5%.Type: GrantFiled: April 23, 2003Date of Patent: October 19, 2004Assignee: Sumitomo Electric Industries, Ltd.Inventors: Akira Kuibira, Masuhiro Natsuhara, Hirohiko Nakata

Publication number: 20040200821Abstract: An electrically conductive coating of an automotive heatable windshield has a communication window having an enhanced frequency selective surface having arranged passing areas (uncoated areas) and blocking areas (coated areas) to pass and block, respectively, predetermined wavelengths of the electromagnetic spectrum. In one nonlimiting embodiment, the frequency selective surface includes a pattern having a first plurality of arcuate break lines on one side of a dividing break line and a second plurality of arcuate break lines on the other side of the dividing break line. An elongated continuous blocking area is between adjacent break lines. The arcuate break lines of a group are nested within one another with the arcuate break line having the largest radius of curvature adjacent the dividing break line. The break lines each have alternating blocking and passing areas.Type: ApplicationFiled: April 8, 2003Publication date: October 14, 2004Inventor: Charles S. Voeltzel

Publication number: 20040195233Abstract: An electrically conductive heated glass panel assembly, control system, and method for producing panels are provided to warm objects and to insure unobstructed viewing through glass by removing moisture. An integrated connection circuit interconnects glass sheets, which have a low emissivity conductive coating deposited thereon. The circuit includes copper bus bars that are disposed onto the conductive coating through the use of a circularly rotating or an inline heating head and mask apparatus. A metallic tab, which extends from the glass sheet's peripheral edge, is disposed onto each conductive metal bus bar for external electrical connectivity. Two types of glazing channels are offered to interconnect multiple panels to external circuits and controls. A solid-state controller may be provided to obtain sensor control signals so as to drive a triac circuit that provides current flow through the panel for the desired heating.Type: ApplicationFiled: April 28, 2004Publication date: October 7, 2004Inventors: Peter F. Gerhardinger, Randall L. Bauman, Dillon R. Ashton
