Patent number: 8732938Abstract: An improved method of packaging a sensor is provided. The method includes the step of affixing a tuning fork to a platform. The tuning fork includes tines comprising one or more surfaces, with each tine further comprising an electrode and a piezoelectric material. An application specific integrated circuit (ASIC) is affixed to the platform. Electrical communication between the ASIC and the electrode of each tine is established for providing stimulus to the tuning fork and for receiving a response signal from the tuning fork. A protective layer is applied to cover the platform and a portion of the tuning fork while maintaining a portion of a surface of each tine free from the protective layer such that the surface can displace the fluid in contact therewith.Type: GrantFiled: May 19, 2010Date of Patent: May 27, 2014Assignees: MEAS France, Hella KGaA Hueck & Co.Inventors: Oleg Kolosov, Leonid Matsiev, John F.

Patent number: 7288229Abstract: An apparatus and method for carrying out and monitoring the progress and properties of multiple reactions is disclosed. The method and apparatus are especially useful for synthesizing, screening, and characterizing combinatorial libraries, but also offer significant advantages over conventional experimental reactors as well. The apparatus generally includes multiple vessels for containing reaction mixtures, and systems for controlling the stirring rate and temperature of individual reaction mixtures or groups of reaction mixtures. In addition, the apparatus may include provisions for independently controlling pressure in each vessel, and a system for injecting liquids into the vessels at a pressure different than ambient pressure.

Patent number: 6727096Abstract: Computer programs and computer-implemented methods for monitoring the progress and properties of parallel chemical reactions. The invention repeatedly receives a measured value or values associated with the contents of each of a plurality of reactor vessels and displays the measured over the course of a combinatorial chemical reaction. Reaction parameters associated with individual reactor vessels are changed in response to the value measured during the reaction. Reaction parameters include temperature, pressure, stirring speed. The reaction occurring in one or more reactor vessels is quenched in response to values measured during the reaction. The measured values are used to calculate experimental results including temperature change, pressure change, percent conversion of starting material, and viscosity. The measured values and experimental results are displayed. In another aspect, the invention features a method for controlling a combinatorial chemical reactor.Type: GrantFiled: November 28, 2000Date of Patent: April 27, 2004Assignee: Symyx Technologies, Inc.Inventors: Pei Wang, G.
