A flexure hinge with two material segments connected to each other via a material tapering to a thin spot which defines a pivot axis between the two material segments. The material segments are provided with recesses such that the strength existing in the thin spot with respect to normal stresses or bending stresses is kept largely constant within a distance from the thin spot.

The present disclosure generally relates to systems and methods for determining a four-dimensional (4D) trajectory of an aircraft without requiring aircraft performance data or meteorological data. The techniques can include: detecting a plurality of 4D aircraft states of the aircraft, determining, for each of a plurality of pairs of adjacent aircraft states, a respective aircraft transition, detecting a plurality of pairs of repeat adjacent aircraft transition, discarding, for each pair of repeat adjacent aircraft transitions, a respective aircraft state from the plurality of aircraft states, and electronically transmitting the plurality of aircraft states after the discarding.

A balance (1) has a weighing pan (3) that is held in a predetermined free-floating and constant position relative to translatory and rotary displacements in the six degrees of freedom during use. At least six position sensors are used to measure the position of the weighing pan in all three dimensions. A weighing mechanism having at least six electromagnetic mechanisms (5) generate compensation forces (F.sub.c1-F.sub.c6) that act on the weighing pan by sending currents through a force coil (7) associated with an associated permanent magnet. The weight of an object on the weighing pan is determined from the amounts of current flowing in the respective force coils to maintain the weighing pan in position.

A balance (10) includes an evacuable housing (12) having a bottom (121), side walls (122), and a top (123), and a weighing device (14) arranged in the housing (12) having a load carrier (142), a weighing system (141) and a weighing sensor. The weighing system (141) has a base fixed to the housing and a load receptor connected to the load carrier (142), which load receptor is coupled to the base in a vertically movable manner via a link arrangement articulated to the base on the one hand and is coupled to the weighing sensor fixed to the base in a force-transmitting manner via a lever arrangement on the other hand. A vertical post (124) protrudes from the center of the bottom (121) of the housing (12), wherein the base of the weighing system (141) is fixed on a free end of the post (124).
