The radar system has multiple transceiver units, which are situated on separate installation supports for the installation in different locations in the motor vehicle and are connected to one another by a synchronization network. Each of the transceiver units has a scanning module for scanning radar signals received on a plurality of channels in the form of a time signals. Each installation support has a raw-data interface for the transmission of the time signal of the transceiver unit to a central evaluation instance. The central evaluation instance is configured to jointly evaluate the time signals from the plurality of transceiver units.

Abstract: A radio-frequency (RF) power variable capacitor capable of operating at, at least, 50 watts in the MHz range. The capacitor has a composite HDK-NDK ceramic dielectric. The HDK (high dielectric constant) component comprises an active matrix of barium strontium titanate, for example. Acoustic resonances are reduced or eliminated by the addition of a metal or metalloid oxide such as magnesium borate (NDK—low dielectric constant), which acts as an acoustic resonance reduction agent (ARRA) in the RF power domain. The acoustic resonances which previously occurred under bias voltage 500 V or 1100 V in prior art RF power variable capacitors are eliminated by the addition of the ARRA.

Abstract: A variable voltage generator circuit is described for generating, from a substantially constant supply voltage VS, a variable high-voltage control voltage VC for a variable power capacitor (1) having a variable-permittivity dielectric. The control voltage generator circuit comprises a top-up circuit (10) for maintaining the voltage VCin on an input capacitor (12) at least at supply voltage VS, and a bidirectional DC-DC converter circuit (20) having a variable voltage conversion factor G controlled by control input signal (27). The bidirectional DC-DC converter (20) is arranged to convert voltage, at the voltage conversion factor G, between the input capacitor voltage VCin and the output voltage VC. When VC<G×VCin, the DC-DC converter circuit (20) uses charge stored in the input capacitor (12) to charge the capacitive load (1). When VC>G×VCin, the DC-DC converter circuit (20) uses charge stored in the load capacitance (1) to charge the input capacitor (12).

The pressure compensator increases pressure resistance of the fluid-tight connection of the functional element to the base body against pressure.

Abstract: A hydraulic circuit for an agricultural implement consisting of a hydraulic cylinder that exerts a force on a component of the implement. A pressure reduction valve located between a hydraulic power source and the hydraulic cylinder maintains pressure to no more than a preset maximum to protect the hydraulic cylinder by routing excess hydraulic fluid back through a hydraulic line into a reservoir. A pressure relief valve with a preset maximum pressure greater than that of the pressure reduction valve is located between the pressure reduction valve and the hydraulic cylinder, and is connected to the reservoir through a dedicated return line. If hydraulic fluid pressure in the circuit increases to greater than the maximum of the pressure reduction valve, hydraulic fluid is diverted back to the reservoir through the pressure relief valve and a dedicated return line.
