| 20090028743 | FORMING MAGNESIUM ALLOYS WITH IMPROVED DUCTILITY - A magnesium alloy comprising up to about one weight percent of cerium may be hot worked to produce an intermediate or final alloy workpiece that exhibits enhanced ductility at room temperature. The addition of a small amount of cerium may affect the magnesium alloy by reducing yield strength, refining grain size, and improving the work hardening behavior. Recrystallization during hot deformation of the rare earth containing magnesium material alters the texture of the alloy and orients the grains in a manner that favors basal slip activity. The alloy thus deforms at room temperature by a combination of twinning and slip mechanisms. | 01-29-2009 |
| 20090116994 | High ductility/strength magnesium alloys - A magnesium alloy comprising up to about six weight percent zinc and up to about one weight percent cerium may be hot worked to produce an intermediate or final alloy workpiece that exhibits enhanced ductility and strength at room temperature. The addition of zinc and a small amount of cerium may affect the magnesium alloy by increasing strength and ductility, and improving the work hardening behavior. | 05-07-2009 |
| 20100083481 | Method for attaching magnesium panels using self-piercing rivet - A method for attaching an aluminum panel to a magnesium panel via a self-piercing rivet. The method includes positioning the aluminum panel and the magnesium panel together with the magnesium panel supported on an anvil having a cavity therein. The magnesium panel is spot heated at the locale of the anvil, and then the self-piercing steel rivet is punched through the steel panel and only partway into the magnesium panel, to displace the magnesium panel into the cavity. The heating of the magnesium improves the ductility so that the self-piercing rivet is accepted without undue strain on the magnesium material. The interface between the steel rivet and the magnesium panel is concealed between the aluminum panel and the magnesium panel to thereby protect the interface between the steel material of the rivet and the magnesium panel from exposure to the environment. | 04-08-2010 |
| 20100092790 | MOLDED OR EXTRUDED COMBINATIONS OF LIGHT METAL ALLOYS AND HIGH-TEMPERATURE POLYMERS - Hybrid articles comprising a molded mixture of a light metal alloy and a polymer are formed by processing (including co-molding and co-extruding) the metal in a semi-solid state at a high shear rate and the polymer in a melt processable state. For example, magnesium alloy particles in a thixotropic condition are mixed with particles or globules of the polymer and molded into a hybrid metal-containing and polymer-containing body. The proportions of magnesium and polymer may be varied substantially depending on the desired properties of the hybrid article. In another embodiment the light metal and polymer may be co-extruded as two or more distinct layers into a solid or hollow hybrid body. | 04-15-2010 |

| 20100143746 | METHODS OF REDUCING CORROSION BETWEEN MAGNESIUM AND ANOTHER METAL - Methods of reducing corrosion between magnesium and another metal are disclosed herein. In one method, a corrosion protection material is cold sprayed at an interface formed between the magnesium and the other metal, the corrosion protection material including magnesium. In another method, a cladding layer is applied to heat affected areas of the magnesium and/or the other metal, at a welded joint, or combinations thereof. | 06-10-2010 |
| 20110030855 | CORROSION RESISTANCE OF THE CAST Mg ALLOYS BY NOVEL MICROSTRUCTURAL PHASE MODIFICATIONS - A method of improving the corrosion resistance of magnesium alloy castings containing more than about 2 per cent by weight of aluminum is described. The method comprises: first selecting a casting process suitable for developing at least on the surface of the casting a microstructure comprising aluminum-depleted magnesium grains surrounded by an aluminum-rich layer and preferably incorporating at least some of an intermetallic compound based on the composition Mg | 02-10-2011 |

| 20110010045 | SENSOR SYSTEM AND METHOD FOR A VEHICLE - A system and method is provided for determining if a windshield wiper of a vehicle should be automatically activated. The system and method may include a sensor system that receives at least one distance signal indicative of a distance between an object and a front windshield of the vehicle. The sensor system may further receive a relative velocity of the object using the at least one distance signal, the relative velocity being indicative of a velocity between the object and the front windshield of the vehicle. The sensor system may determine whether a windshield wiper should be automatically activated in response to the distance signal being within a distance activation range and the relative velocity being within a velocity activation range or the relative velocity exceeding a maximum velocity threshold. | 01-13-2011 |

| 20090183929 | Writing system with camera - A Micro Inertial Measurement Unit (IMU) which is based on MEMS accelerometers and gyro sensors is developed for real-time recognition of human hand motions, especially as used in the context of writing on a surface. Motion is recorded by a motion/acceleration sensor, which may be a combination of a rate rate gyro and an accelerometer, and possibly in combination with a video camera set to detect markers located on a board, with the camera utilizable to detect lines and markers and to determine the proximity of the white board. The immediate advantage is the facilitation of a digital interface with both PC and mobile computing devices and perhaps to enable wireless sensing. | 07-23-2009 |

| 20080264131 | METHOD AND APPARATUS FOR GAS MANAGEMENT IN HOT BLOW-FORMING DIES - A method and apparatus for forming a sheet of ductile material by superplastic forming is disclosed. The method is directed to first creating a pre-form by mechanical forming in which the pre-form is created with a die and punch. Thereafter the pre-form is subjected to gas pressure in a forming cavity to complete formation of the part. A metallic gasket is provided to ensure that no pressurized gas escapes from the forming cavity. | 10-30-2008 |
| 20090205394 | METHOD AND APPARATUS FOR SUPERPLASTIC FORMING - The present invention provides a method and apparatus for forming a ductile sheet or work piece into a part or component. The method includes using a forming apparatus wherein the workpiece is placed between and upper die and a blank holder and then lowered onto a punch such that continued lowering of the upper die draws the workpiece around the punch. Once the draw process is complete, gas pressure acts on one side of the workpiece to press the workpiece against a forming surface of the punch to complete the forming process. | 08-20-2009 |
| 20100192659 | Elevated temperature forming method and preheater apparatus - An elevated temperature forming system in which a sheet metal workpiece is provided in a first stage position of a multi-stage pre-heater, is heated to a first stage temperature lower than a desired pre-heat temperature, is moved to a final stage position where it is heated to a desired final stage temperature, is transferred to a forming press, and is formed by the forming press. The preheater includes upper and lower platens that transfer heat into workpieces disposed between the platens. A shim spaces the upper platen from the lower platen by a distance greater than a thickness of the workpieces to be heated by the platens and less than a distance at which the upper platen would require an undesirably high input of energy to effectively heat the workpiece without being pressed into contact with the workpiece. | 08-05-2010 |
