Patent number: 9016232Abstract: A paper coater includes a frame, an entry guide roll and an exit guide roll both carried by the frame and along a path of travel of a continuous paper sheet. The paper coater includes independently controllable hot wax applicators carried by the frame between the entry and exit guide rolls. Each independently controllable hot wax applicator includes a press roll, an engraved applicator roll opposite the press roll so that the continuous paper sheet is therebetween, and with the engraved applicator roll extending into a hot wax reservoir to pick up hot wax. Each wax applicator includes a doctor blade adjacent the engraved applicator roll to control a thickness of hot wax. At least one selectively operable positioner relatively moves the press and engraved applicator rolls between active and idle positions. The paper coater provides different wax application rates and can be reconfigured relatively quickly between different application rates.Type: GrantFiled: June 25, 2012Date of Patent: April 28, 2015Assignee: Profero Systems, Inc.Inventors: Thomas B. Jones, Oscar Eberhard, Kenneth I. Park

Patent number: 8228657Abstract: Embodiments of the invention are directed to apparatus, methods, and applications involving the actuation of a semi-insulative working fluid by electromechanical forces based on electrowetting-on-dielectric (EWOD) and liquid dielectrophoresis (liquid DEP) mechanisms that are controlled by the frequency, but not the magnitude, of an AC voltage (i.e., ‘frequency-addressable). In the various apparatus embodiments of the invention, a single, frequency-addressable electrode pair includes at least one electrode that has a spatially-varying dielectric coating thickness and thus a spatially-varying electrode gap wherein at least a portion of which a volume of a working fluid can stably reside under no influence of an applied voltage. In an exemplary aspect, a frequency-addressable, bistable apparatus includes at least one wider gap and one narrower gap associated, respectively, with a thicker and a thinner dielectric coating thickness of the electrode(s).Type: GrantFiled: January 16, 2008Date of Patent: July 24, 2012Assignee: University of RochesterInventors: Thomas B.

Patent number: 7658829Abstract: The invention integrates a two-stage dielectrophoretic (DEP) droplet dispensing and distribution system with particulate DEP to create a novel LOC platform capable of manipulating biological cells based on the varied dielectrophoretic signatures that distinguish cells in a population, for example, healthy from diseased cells. The two-stage DEP droplet transport system acts as the backbone of this application, providing the essential dispensing and distribution function, while particulate DEP provides the critical capability to characterize and analyze the heterogeneous biological cell populations routinely encountered in biotechnology and clinical settings.Type: GrantFiled: October 25, 2005Date of Patent: February 9, 2010Assignees: UTI Limited Partnership, University of RochesterInventors: Thirukumaran T.

Patent number: 7267752Abstract: Rapid, size-based, deposition of particles from liquid suspension is accomplished using a nonuniform electric field created by coplanar microelectrode strips patterned on an insulating substrate. The scheme uses the dielectrophoretic force both to distribute aqueous liquid containing particles and, simultaneously, to separate the particles. Size-based separation is found within nanoliter droplets formed along the structure after voltage removal. Bioparticles or macromolecules of similar size can also be separated based on subtle differences in dielectric property, by controlling the frequency of the AC current supplied to the electrodes.Type: GrantFiled: July 26, 2005Date of Patent: September 11, 2007Assignee: University of RochesterInventors: Michael R. King, Oleg Lomakin, Thomas B. Jones, Rajib Ahmed

Patent number: 6573725Abstract: A sensor for an electrostatic detector including an elongated vibratory element supported at a mechanical node at one end in the manner of a cantilever beam, a sensitive electrode on the vibratory element near the other end and adapted to be disposed toward an electrical charge, field or potential being measured, and a driver transducer on the vibratory element for vibrating the element in a direction to vary the capacitive coupling between the electrode and the electrical charge, field or potential being measured. The driver transducer is at a location along the beam and is operated at a vibratory frequency such that a virtual mechanical node appears along the beam. This, in turn, reduces vibration at the mechanical attachment node so that the degree of stiffness of the mechanical node does not affect the operating frequency and/or the displacement at the free end of the cantilever.Type: GrantFiled: August 24, 2001Date of Patent: June 3, 2003Assignee: Trek, Inc.Inventors: Jerzy Kieres, Nenad Nenadic, Thomas B. Jones
