Patent number: 7927882Abstract: A method and apparatus for performing a first measurement on a biological fluid or control, which first measurement varies with both the concentration of a first component and at least one of the presence and concentration of a second component. The method and apparatus perform a second measurement on the biological fluid or control, which second measurement varies primarily only with the at least one of the presence and concentration of the second component to develop an indication of the at least one of the presence and concentration of the second component. The first and second measurements may be made sequentially or simultaneously. The method and apparatus then remove an amount representative of the indicated presence or concentration of the second component from the concentration of the first component indicated by the first measurement.Type: GrantFiled: August 8, 2005Date of Patent: April 19, 2011Assignee: Roche Diagnostics Operations, Inc.Inventor: Zindel Herbert Heller

Patent number: 4388822Abstract: A three-wire digital atmospheric sampling system, particularly adapted to detect methane in mines, wherein accuracy is increased by ratiometric analog-to-digital conversion synchronized by a microprocessor. A reset signal, and read-out pulses indicative of the atmospheric condition, are transmitted along the same signal wire as are digital ratiometric signals, thus enabling the use of three conductors only between an atmospheric sampling probe, a microprocessor, and a visual read-out console.Type: GrantFiled: July 15, 1981Date of Patent: June 21, 1983Assignee: Mine Safety Appliances CompanyInventor: Herbert Heller

Patent number: 4258230Abstract: A party line telephone system capable of effecting selective calling from one station to another and particularly adapted for use in battery-powered two-wire telephone systems such as those used in underground mines where consideration of intrinsic safety, low power consumption and compatibility with existing equipment are paramount. The system of the invention is such that the receiver at each station in the network need not be connected to a battery-powered source for any prolonged period of time except when that station is being called by another station for a private conversation, thereby conserving battery power.Type: GrantFiled: June 15, 1979Date of Patent: March 24, 1981Assignee: Mine Safety Appliances CompanyInventors: Herbert Heller, Paul W.
