Patent number: 9582771Abstract: The present disclosure relates to a Turing machine having a reactor comprising a reactant solution comprising a reactant; a first chemical species source to provide a selected amount of a first chemical species; a second chemical species source to provide a selected amount of a second chemical species; one or more controllers coupled to control the addition of the first and second chemical species from the first and second chemical species sources responsive to an input; and a sensor positioned to sense changes in the reactant as the controller controls the first and second chemical species sources to add selected amounts of the respective first and second chemical species to the reactor. The controller receives signals corresponding to the state of the reactant and correlates the states of the reactant to a result that is computed as a function of the input.Type: GrantFiled: January 11, 2013Date of Patent: February 28, 2017Assignees: PRESIDENT AND FELLOWS OF HARVARD COLLEGE, REPSOL SAInventors: Juan Perez-Mercader, Marta Dueñas-Diez, Daniel Case

Patent number: 8097209Abstract: The invention relates to a method and apparatus for detecting substances or analytes form the analysis of one or several samples. The method comprises mixing the sample with a suitable liquid buffer, homogenizing said sample, adding reagents thereto, filtering it, injecting the sample into the incubation chamber, allowing the sample to react with a biosensor, washing the non-reacted sample excess and detecting the sample retained in the biosensor. The apparatus includes a sample homogenizer module with an ultrasonic piezoelectric device formed by a converter (49) and a horn (16); a sample processing module including a homogenization container (6) and a moving frame (17); a reagent and solution management module including a motorized syringe (60), a reaction module consisting of a support (50) forming a reaction chamber (51) and a data reading module including a laser diode (66) and a CCD camera (67).Type: GrantFiled: May 28, 2004Date of Patent: January 17, 2012Assignees: Instituto Nacional de Technica Aerospacial “Easteban Terradas”, Sener, Ingenieria Sistemas, S.A., Consejo Superior de Investigaciones CientificasInventors: Javier Gómez-Elvira Rodríguez, Eduardo Sebastián Martínez, Carlos Briones Llorente, Victor Parro García, José Antonio Rodríguez Manfredi, Carlos Compostizo Sañudo, Pedro Luis Herrero Gonzalo, Juan Pérez Mercader
