Publication number: 20220363286Abstract: An object recognition determination produced by a perception system from data received from a ranging sensor system can be verified. A certificate can be produced that includes data for points of readings from the ranging sensor system. The points can have been segmented, by the perception system, into point sets that correspond to objects in an environment of a cyber-physical system. The certificate can also include lists of pairs of points in a point set and a velocity of the point set. A test of information in the certificate can be performed. Based on a result of the test: a rectification can be made to the perception system or the ranging sensor system or a communication can be transmitted to a control signal production module configured to produce, in response to the communication, a control signal to be transmitted to an actuator system configured to control the cyber-physical system.Type: ApplicationFiled: May 14, 2021Publication date: November 17, 2022Applicants: Toyota Research Institute, Inc., Massachusetts Institute of Technology, Universidade Federal de Minas GeraisInventors: Daniel Jackson, Soon Ho Kong, Nikos Arechiga Gonzalez, Anna G.

Patent number: 9085487Abstract: The present invention describes a chemical vapor-phase deposition for carbon nanotube synthesis in which cement clinker is used as a ceramic matrix for anchoring transition-metal nanoparticles. Using cement clinker as nanoparticle anchoring base of transition metals allows carbon nanotubes to be generated on cement clinker particles and grains, in this way producing a kind of cement that is nanostructured with carbon nanotubes. By this process, the carbon nanotube synthesis and integration to clinker are carried out in just one continuous and large-scale stage. The process described herein can be applied to conventional cement industry whose production may be rated as tons per day. The present invention also proposes—as part of the carbon nanotube synthesis on cement clinker—several enrichment alternatives of cement clinker by using transition metals for producing such nanostructured composite, which may or not be integrated to the conventional cement industry.Type: GrantFiled: April 30, 2009Date of Patent: July 21, 2015Assignee: UNIVERSIDADE FEDERAL DE MINAS GERAISInventors: Edelma Eleto Da Silva, Luiz Orlando Ladeira, Rodrigo Gribel Lacerda, Sérgio De Oliveira, André Santarosa Ferlauto, Eudes Lorençon, Erick De Sousa Ávila
