Abstract: Methods, devices, and systems are described for enrolling a user's bring-your-own-device for secure connection to a company's enterprise computer network. From her mobile device, user clicks on a uniform resource locator (URL) to connect with the login web page on the enterprise network. After authentication, checks are performed to verify that the user has authorization to enroll the type of electronic device, and the profile is installed on the device. A notification is sent to the device by a server on the enterprise network, and a secure workspace application is pushed to the device along with configuration data that automatically links the workspace with the parent device enrollment. Once the user launches the secure workspace application the workspace access configuration data and initializes enrollment with the enterprise network, resulting in a linking of the secure workspace application with its parent device enrollment.

Abstract: The formability of coiled and annealed (O-temper) magnesium alloy sheet material in high temperature forming operations is sometimes adversely affected by small amounts of cold work introduced into the fine grained material during handling of the coil and unwinding it to obtain blank workpieces for hot stamping, hot blow forming, or the like. When necessary, the formability of the sheet material with regions of hard worked microstructure may be improved by predetermining a recovery heat treatment using small portions of the material in formability tests. The recovery heat treatment, determined for the specific coiled stock, may then be applied to the material of the coil as it is used in making vehicle body panels or the like.

Abstract: Metal sheets and thin-wall metal tubes may be heated to a hot working temperature and transformed by a hot-blow-forming step to achieve shapes, difficult to attain, without excessive thinning or strain causing damage to the workpiece based on the inherent formability of the metal alloy. The stages of forming of the intended shape in the metal workpiece are analyzed and workpiece regions of potential damage during forming are identified. Then, during actual forming, these regions of the hot workpiece are selectively cooled with air (or other cooling fluid) to reduce thinning or strain in the critical region(s) and to redistribute this strain to adjacent lower strain areas of the workpiece. This hot-blow-forming practice is particularly useful in attaining complex shapes in workpieces of aluminum-based alloys and magnesium-based alloys.

In an example embodiment, the apparatus includes a far-field superlens that is adapted to generate a sub-wavelength image or a sub-diffraction-limited image at a far field distance from a negative-index material included in the superlens. The example far-field superlens includes a positive-index material and an adjacent positive-index material. The negative-index material has an output aperture at a first surface. A second surface or interface is positioned at a far field distance from the negative-index material such that a cavity or gap is formed between the second surface and the first surface, wherein the second surface represents an imaging surface. The gap may be filled with a dielectric material or may include a vacuum or air.

Abstract: Magnesium and other metal alloy sheet materials are deformed at hot forming temperatures into vehicle body panels and other articles. Many such hot forming operations are improved in speed and product quality by predetermining a static recrystallization temperature of the sheet material. As the sheet material is being heated to its hot forming temperature, deformation is commenced below the static recrystallization temperature. As heating and deformation are continued, dynamic recrystallization of the workpiece occurs and deformation may proceed faster and to a greater extent.

Abstract: A method is disclosed for stretching magnesium-containing aluminum alloy sheet stock into intricate shapes such as are required in automotive body panels. The sheet stock, at a temperature in the range of about 400° C. to about 510° C., is stretched under the pressure of a working gas into conformance with the surface of a forming tool. The sheet forming pressure is increased continually in a controlled manner from ambient pressure to a final forming level in the range of about 250 psi to about 500 psi or higher. A portion of the sheet can experience strain rates substantially higher than 10?3 sec?1 and the forming of the sheet can be completed within 12 minutes.
