Abstract: A method for designing a sensor arrangement, in particular for a vehicle or a vehicle class. Dimensions of vehicles of at least one vehicle class are ascertained and geometric parameters are ascertained from the dimensions of the vehicles of the vehicle class. Predefined reference fields for sensors of vehicles of the at least one vehicle class are established based on the derived geometric parameters. Each reference field is configured to accommodate at least one sensor. A sensor arrangement is also described.

Abstract: A hand power tool that can be folded in its longitudinal span, having a housing base body that holds the driven tool insert and whose axis is adjustable—relative to the axis of a housing part serving as a handle—around a folding axis, is made especially compact and lightweight in that the hand power tool is embodied in the form of a universal saw that has the ability to be locked in various angular positions of the housing parts relative to one other; the housing part contains the drive motor, whose driven rotary motion is transmitted via an angle transmission to the tool insert—a saw blade—that is guided in the housing base body.

Abstract: A hand power tool (10) that can be folded in its longitudinal span, having a housing base body (12) that holds the driven tool insert (14, 15) and whose axis is adjustable—relative to the axis of a housing part (11) serving as a handle—around a folding axis (13), is made especially compact and lightweight in that the hand power tool (10) is embodied in the form of a universal saw that has the ability to be locked in various angular positions of the housing parts (11, 12) relative to one other; the housing part (11) contains the drive motor (19), whose driven rotary motion is transmitted via an angle transmission (23, 35) to the tool insert—a saw blade (13, 14)—that is guided in the housing base body (12).

Abstract: An electric power tool (10) having a housing (12) from which a power cable (22) leads, is safer for the user because the circumference of the power cable (22) has lighting means (21, 26, 28, 30) along its longitudinal span, whose light makes the power cable (22) easily visible to the human eye in the dark.
