Abstract: Heated garments that are flexible, stretchable, and durable are described, along with methods for constructing such garments. The heated garments comprise a garment body, a heating wire forming a heater array stitched to a heating section of fabric, and a main current line for providing electrical current to the heating wire. A transition element is formed over the connection of the heating wire and the main current line to induce formation of a fabric flex line such that the heating wire is subjected predominately to torsion forces instead of flexion forces upon flexion at the fabric flex line. The heated garment includes a flexible thermally conductive and electrically resistive material covering the heating wire. The heater array may be integral to the garment body or may be removable.

The optical arrangement generates a focal line along the beam direction.

The moving device generates relative movement between the laser beam and the workpiece along the predetermined processing line.

Abstract: A method for separating a portion from a sheet glass element having a thickness of at least 2 millimeters along an intended separation line that divides the sheet glass element into the portion and a remaining main part is provided. The method includes producing filamentary damages comprising sub-micrometer hollow channels in a volume of the glass sheet element adjacently aligned along the separation line; and heating and/or cooling the glass sheet element to cause expansion and/or contraction so that the portion detaches from the main part along the separation line. The portion and the remaining main part each remain intact as a whole. The step of producing the filamentary damages includes generating a plasma within the volume with laser pulses of an ultrashort pulse laser; and displacing points of incidence of the laser pulses over a surface of the glass sheet element along the separation line.

Abstract: A wheel for a two-track motor vehicle has a rim, a hub, and multiple spokes arranged distributed in the circumferential direction and each having a radially inner end and a radially outer end. The hub is arranged asymmetrically relative to a vertical wheel central plane extending perpendicular to a rotational axis direction of the wheel.

Abstract: The present technology is essentially a portable seismic survey system and method using reflection seismology for mapping subterranean formations. The device includes an upper assembly, a firing pin operably associated with a firing pin actuator, a lower assembly including a cartridge holder capable of retaining a blasting cartridge, and a detonation sensor capable of detecting detonation of the blasting cartridge. The system can further include an anchoring assembly, and an adjustable shield assembly. The detonation sensor transmits a signal to an event marking device to trigger a recordation of detonation time and geographic location of the seismic survey device. A seismic wave is generated upon detonation, which is then reflected back toward seismometers. Data from the event marking system and seismometers can then be processed to provide geological formation information.
