Patent number: 9738123Abstract: A vehicle warning includes a tire pressure monitoring device disposed in each tire of the vehicle. Each tire pressure monitoring device obtains information regarding pressure within the associated tire and communicated the tire pressure information in a wireless manner. A receiver receives the communicated tire pressure information from each tire pressure monitoring device. A processor circuit, associated with the receiver, determines if the communicated tire pressure information from at least one of the tire pressure monitoring devices is significantly less than a tire pressure determined to be safe for vehicle operation and, if so, to generate a warning signal. A body control module, upon receiving the warning signal, automatically activates the hazard lights without driver input.Type: GrantFiled: August 14, 2015Date of Patent: August 22, 2017Assignee: Continental Automotive Systems, Inc.Inventors: David Cruz Mendez, Ernesto Amezcua Maciel, Ignacio Padilla Rabadan, Carlos Alfonso Rodriguez Gomez

Publication number: 20090266358Abstract: A vaporizer and cartridge system are disclosed. The vaporizer may be considered a universal vaporizer in that the vaporizer may use several different liquid anesthetic materials rather than just one. The cartridges may be single-use cartridges that are disposed after use rather than refilled by an end user. The cartridges may have one or more memory devices within the cartridge so that information about the cartridge may be communicated to the vaporizer such as the type of liquid anesthetic material carried by this cartridge. The vaporizer/cartridge system may be implemented to allow the vaporizer to update information in the cartridge memory such as the amount of liquid anesthetic material that was consumed during a particular session of use of the cartridge. The vaporizer may maintain a virtual logbook with information about the operation of the vaporizer.Type: ApplicationFiled: March 30, 2009Publication date: October 29, 2009Applicant: INNOVAMEDICA S.A.P.I. de C.V.Inventors: Emilio Sacristan Rock, Fernando Fabian Hernandez Hernandez, Carlos Alfonso Rodriguez Sierra, Jose Guillermo Saavedra Roman
