Publication number: 20060284077Abstract: An instrument for non-invasively measuring nanoparticle exposure includes a corona discharge element generating ions to effect unipolar diffusion charging of an aerosol, followed by an ion trap for removing excess ions and a portion of the charged particles with electrical mobilities above a threshold. Downstream, an electrically conductive HEPA filter or other collecting element accumulates the charged particles and provides the resultant current to an electrometer amplifier. The instrument is tunable to alter the electrometer amplifier output toward closer correspondence with a selected function describing particle behavior, e.g. nanoparticle deposition in a selected region of the respiratory system. Tuning entails adjusting voltages applied to one or more of the ion trap, the corona discharge element and the collecting element. Alternatively, tuning involves adjusting the aerosol flow rate, either directly or in comparison to the flow rate of a gas conducting the ions toward merger with the aerosol.Type: ApplicationFiled: May 23, 2006Publication date: December 21, 2006Applicant: TSI IncorporatedInventors: Heinz Fissan, Andreas Trampe, David Pui, Stanley Kaufman

Publication number: 20050248750Abstract: A system is disclosed for condensation particle counting in conjunction with modifying an aerosol to enhance the formation and growth of droplets of a selected working fluid, preferably water. Before saturation with the working fluid, the aerosol is exposed to an aerosol modifying component, preferably a vapor including molecules that are adsorbed onto surfaces of the particles or other elements suspended in the aerosol. Adsorption alters the surface character of the suspended elements towards increased affinity for the vapor of the working fluid, to promote the formation and growth of working fluid droplets. The droplets are optically detected to indicate numbers and concentrations of the suspended elements.Type: ApplicationFiled: May 9, 2005Publication date: November 10, 2005Applicant: TSI IncorporatedInventors: Richard Flagan, Stanley Kaufman, Gilmore Sem

Patent number: 5825869Abstract: A call-management method and system for distributing calls to individuals, such as ACD agents, include storing a resume for each individual. In the preferred embodiment, each resume includes first data indicative of call-handling capabilities of the individual and includes second data indicative of preferences of the call-management system for particular individuals to process particular types of calls. When an inbound call is received or an outbound call is generated, the call is tagged with identification of abilities advantageous to processing the calls. Thus, the desired skills for a call may be correlated with either or both of the call-handling capabilities of the individuals and the call-management preferences. Again referring to the preferred embodiment, "tagging" each call is a step of associating a skill expression with each call and includes identifying two or more desired abilities for processing the call.Type: GrantFiled: April 23, 1996Date of Patent: October 20, 1998Assignee: Siemens Business Communication Systems, Inc.Inventors: Nancy Sinling Brooks, Paul Douglas Fryer, Gary Stanley Kaufman, Stephen Phillip Berkson, Charles R. Herel, Laura M. Brooks

Patent number: 5285513Abstract: A cable of this invention includes a core comprising a plurality of coated optical fibers and a filling composition of matter which is disposed about the fibers. Typically, the fibers and the filling material are diposed within a tubular member which is disposed within a sheath system. The sheath system include longitudinally extending strength members and a plastic jacket. The filling composition which fills interstices in the core is one which includes an oil constituent which is a relatively high molecular weight aliphatic hydrocarbon. The aliphatic hydrocarbon is a synthetic oil such as polyalphaolefin or mineral oil. A relatively large percent by weight of an antioxidant system is used to prevent thermal oxidative degradation of the filling material as well as of materials in contact with the filling material. Advantageously, for stabilization and metal deactivation, the composition includes zinc dialkyldithiophosphate or diaryldithiophosphate.Type: GrantFiled: November 30, 1992Date of Patent: February 8, 1994Assignee: AT&T Bell LaboratoriesInventors: Stanley Kaufman, Jim J.

Patent number: 5270486Abstract: An insulated conductor (20) for use in a communication cable which includes a filling material (30) includes a copper conductor (25) and a composite insulation system (27) comprising two concentric layers of insulation. An inner foam layer (28) of the insulation comprises a cellular plastic material (28) which includes a stabilizer system. An outer layer (29) of the insulation is referred to as a skin and comprises a stabilized solid plastic material. The stabilizer system in each of the cellular and solid layers includes a bifunctional portion that functions as an antioxidant and as a metal deactivator and that has a relatively high resistance to extraction. The level of the bifunctional portion of the stabilizer in the cellular material is substantially greater than that in the skin inasmuch as it has been found that the level of the stabilizer cellular layer contiguous to the copper wire determines the oxidation performance level of the composite insulation.Type: GrantFiled: May 29, 1992Date of Patent: December 14, 1993Assignee: AT&T Bell LaboratoriesInventors: Maureen G. Chan, Kent B. Connole, Timothy S. Dougherty, Karen D. Dye, Stanley Kaufman, Valerie J. Kuck, Leonard D. Loan, deceased, Edward D. Nelson, Raffaele A. Sabia

Patent number: 4657346Abstract: Disclosed is a method and resulting package which provide an optical fiber seal. One or more fibers are fed through a housing utilizing an apertured insert with a fiber located in each aperture. The housing preferably includes adjacent openings having unequal diameters. A sealing material, such as epoxy is deposited in the larger opening, and/or in the apertures, and the insert is pushed into that opening. The sealing material is thereby forced through the small opening and also into the apertures of the insert to seal the fibers.Type: GrantFiled: February 21, 1984Date of Patent: April 14, 1987Assignees: American Telephone and Telegraph Company, AT&T Technologies and AT&T Bell LaboratoriesInventors: Robert W. Berry, Stanley Kaufman, Friedrich Zwickel

Patent number: 3981947Abstract: In-service PIC telephone cable that has become water-logged in places is reclaimed dielectrically by pumping in an aromatic solvent oil containing cross-linking agents that will gel the oil in a predetermined period preferably of the order 24 hours. A nongelling prepurgent miscible with both water and aromatic solvent oil may be pumped in before the gelling compound is introduced, to more completely purge the water.Type: GrantFiled: November 22, 1972Date of Patent: September 21, 1976Assignee: Bell Telephone Laboratories, IncorporatedInventors: Stanley Kaufman, Raffaele Antonio Sabia

Patent number: 3944717Abstract: A telephone service cable which runs from a distribution cable to a subscriber's premises or to a pay station is another link in a buried communications system having a water-resisting capability. A spirally quaded core comprised of individually insulated conductors is advanced through a bath of a flame-retardant, water-resistant composition prior to enclosing the core with a jacket. The interstices in the core and between the core and an inner jacket are caused to be filled with the composition which comprises a liquid system and a solid system. The liquid system includes a chlorinated paraffin while the solid system includes a polyvinyl chloride resin and a chlorinated polyethylene. An epoxy stabilizer and a phosphite stabilizer may be added to prevent thermal degradation of the filling composition.Type: GrantFiled: August 15, 1973Date of Patent: March 16, 1976Assignees: Western Electric Company, Inc., Bell Telephone Laboratories, Inc.Inventors: Joseph Michael Hacker, Stanley Kaufman, Raffaele Antonio Sabia, Earl Salvator Sauer, Charles Edward Tidd, Jr., Raymond Walker
