20120179353 | METHOD OF MONITORING AN ENGINE COOLANT SYSTEM OF A VEHICLE - A method of monitoring an engine coolant system includes modeling the total energy stored within an engine coolant. If an actual temperature of the engine coolant is below a minimum target temperature, the modeled total energy stored within the energy coolant is compared to a maximum stored energy limit to determine if sufficient energy exists within the engine coolant to heat the engine coolant to a temperature equal to or greater than the minimum target temperature. The engine coolant system fails the diagnostic check when the modeled total energy stored within the energy coolant is greater than the maximum stored energy limit, and the minimum target temperature has not been reached. | 07-12-2012 |

20130089436 | DIAGNOSTIC SYSTEM AND METHOD FOR A SWITCHABLE WATER PUMP - A system includes a pump control module and a pump diagnostic module. The pump control module switches a switchable water pump from off to on. The pump diagnostic module diagnoses a fault in the switchable water pump based on a first difference between an engine material temperature and an engine coolant temperature when the switchable water pump is switched from off to on. The engine coolant temperature is a temperature of coolant circulated through an engine and the engine material temperature is a temperature of at least one of an engine block and a cylinder head. | 04-11-2013 |
20150082931 | SHIFT-BY-WIRE SYSTEM FOR A VEHICLE, AND A TRANSMISSION RANGE SELECTION METHOD THEREOF - A method for determining a transmission range selection of a shift-by-wire system, which includes a shift lever, a park button, and a controller, is provided. The shift lever is movable between a plurality of transmission range positions, each corresponding to a transmission range, and a null position. The park button is switchable between a pressed position corresponding to a Park transmission range, and a released position. The method includes determining, by the controller, if at least one predetermined condition exists. If it does, then the controller determines the transmission range selection to be the Park transmission range. Otherwise, the controller determines the transmission range selection to be the transmission range corresponding to the transmission range position in which the shift lever is positioned. | 03-26-2015 |
20150088387 | POSITION DIAGNOSTIC TEST FOR A SHIFT-BY-WIRE SYSTEM, AND A METHOD THEREOF - A position diagnostic test for a shift-by-wire system is provided. The shift-by-wire system includes a shift lever configured to move along a shift path, a first and a second position sensor configured to generate a first and a second position signal, respectively, of the shift lever along the shift path, and a controller configured to receive the first and second position signals. The first position sensor includes a first x-coordinate value and a first y-coordinate value, and the second position sensor includes a second x-coordinate value and a second y-coordinate value. The position diagnostic test includes performing a rationality test on each of the coordinate values. If at least one predetermined condition exists for a particular coordinate value, then it fails the rationality test, and the position signal containing the coordinate value may be disregarded. | 03-26-2015 |

20090005848 | MODULAR VASCULAR PROSTHESIS AND METHODS OF USE - The present invention relates a vascular prosthesis and related assembly methods that includes a plurality of modular segments inter-engaged by flexible, and preferably lockable, inter-engageable elements forming joints or other connector areas. The segments may have a number of different mechanical properties and may be assembled by the clinician, through mechanical or chemical joining, to customize the prosthesis for a specific patient or application. | 01-01-2009 |
20110004294 | FATIGUE-RESISTANT STENT - A fatigue-resistant implantable medical device. The fatigue-resistant implantable medical device includes a tubular stent. The tubular stent can have a laser-cut length and a shape-set length that is either longer or shorter than the laser-cut length. Such stents will tend to return to their laser-cut length when they are compressed for delivery. A stent that is shape-set longer than its laser-cut/delivery length that is deployed in a vessel that is shortened for stent delivery will tend to return to its shape-set length when the vessel returns to its neutral (i.e., elongated) length. Likewise, a stent that is shape-set shorter than its laser-cut/delivery length that is deployed in a vessel that is elongated for stent delivery will tend to return to its shape-set length when the vessel returns to its neutral (i.e., shortened) length. Such stents will experience reduced axial loading and reduced mean strain, thereby improving fatigue life. | 01-06-2011 |
