    Abstract: In order to provide a method and apparatus for forming a sheet metal, in which a three-dimensional product such as a prototype for commercialized press-forming can be formed in short time without limitations as to the shape and with high accuracy, preventing body wrinkles or reduction of the sheet thickness, a process of: performing drawing-forming to a predetermine height by pushing the forming punch having a desired shape in the sheet thickness direction with the edges of the blank workpiece being clamped; performing shape-forming with the shaping tool in the opposite side to the forming punch by increasing a clamping pressure to lock movement of a material with the forming punch being pushed; performing drawing-forming again by decreasing the clamping pressure and raising the forming punch by a desired height; and performing shape-forming with the shaping tool by increasing the clamping pressure to lock movement of a material, is repeated at least once.

    Abstract: An electrosurgical instrument includes a shaft, a flexible portion, and a head coupled to the shaft through the flexible portion and pivotably coupled to the flexible portion. The head includes a non-conductive surface and an electrically conductive surface. The flexible portion is configured to bias the non-conductive surface and the electrically conductive surface towards a tissue surface, such as cartilage. The non-conductive surface may include a material having a thermal conductivity less than or equal to about 30 W/m*K and/or a volume resistivity greater than or equal to about 1×1014 ohm*cm. The non-conductive surface may include a ceramic such as Macor® ceramic, ZTA ceramic, and/or 99.5% alumina ceramic.

    Abstract: In a device for adjusting a vehicle's head support with reference to the position of a passenger's head, with a sensor disposed in the head support for detecting the position of the head, the sensor contains two condenser plates which are arranged one above the other and are part of a condenser, in which the head of the passenger acts as a dielectric. In the method for the adjustment of the vehicle's head support, the height is varied, starting from a rest position with the head support retracted, to such an extent that the increase of the sensor signal of the one condenser plate takes place simultaneously with the decrease of the sensor signal of the other condenser plate.
