Abstract: An operation assistance system includes a support column as well as at least a first and second robotic arm. A lower end section of the support column is pivotally mounted about a first pivotal axis (SA1) on a base unit and controlled by a first drive unit. A first end section of the first robotic arm is pivotally mounted about a second pivotal axis (SA2) on the upper end section of the support column opposite to the base unit and controlled by a second drive unit. A first end section of the second robotic arm is pivotally mounted about a third pivotal axis (SA3) on a second end section of the first robotic arm by a third drive unit. Each drive unit is associated with a controllable magnetic brake unit by which the robotic kinematics can be uncoupled from the drive units.

Abstract: An apparatus for making a foam material body has a mold comprising at least two mold halves fittable together to form separate first and second mold cavities; a first sprue opening into the first mold cavity, and a second sprue opening into the second mold cavity. The mold parts can be moved between an open and a closed position. Foam can be injected into the first and second mold cavities through the respective sprues. A passage, for example, connects the sprue with the mold cavity. The first mold cavity and the second mold cavity are partitioned from one another in the closed position of the mold.

Abstract: A measuring device (e.g., a vectorial network analyzer) by means of at least two ports can be connected to a device under test and has associated excitation/receiving units (ERUs), each thereof having one port. At least one ERU has a signal generator, which can apply an excitation signal onto a device under test. Each ERU possesses two receiving apparatuses (each with a mixer in connection with an oscillator signal) to receive the excitation signal, the reflected signal from the associated port or the signal transmitted to the associated port and converts said signal into an intermediate signal. Each ERU exhibits its own oscillator separate from the signal generator, and generates the oscillator signal for the mixer of the receiving apparatus of the ERU, whereby the frequency and/or phase of the oscillator signals, can be adjusted independently of the frequency and/or phase of oscillator signals of the oscillators of other ERUs.

Abstract: A diffuser for slowing down a fluid and a method for operating a diffuser is described. A channel of the diffusor has an inlet with a smaller flow cross section than a flow cross section of an outlet and at least one opening for receiving an energizing fluid to be transported selectively into the channel. Pulsations of the impact interface are suppressed effectively at all of the operating points by injecting the energization fluid. Pressures of the fluid moving in the diffusor are measured, and amplitudes and frequencies of the measured pressures are evaluated. Energizing fluid is fed into the diffusor if the amplitudes within a predetermined frequency band exceed a threshold value. The utilization ratio of the inventive diffuser is considerably improved as a result of such a measure.

Abstract: The invention provides a method and apparatus for controlling gas circulation in a fuel cell system in which a stack of fuel cells is surrounded by a protective housing. According to the invention, used cathode gas and burnt combustion gas from the fuel cell stack directly into the interior of a protective housing which surrounds the fuel cell stack. A blower which is arranged inside the housing causes the used cathode gas to mix with the burnt combustion gas and recirculate to the cathode input of the fuel cell stack, where it is further with fresh gas from the exterior.
