Abstract: A method for determining phase information related to an RF transmission channel includes generating an RF signal, coupling a first representation of the RF signal to the RF transmission channel to generate an RF output signal, and coupling a second representation of the RF signal to a test phase shifter. Generating a down-converted signal based on mixing a representation of the RF output signal with each respective RF test signal of a set of RF test signals, sampling the down-converted signal to generate for each target phase shift value of a set of predetermined target phase shift values a respective measurement sample of a set of measurement samples. A set of non-uniformly distributed values is applied in an operation acting on a set of measurement samples to determine first-order harmonic information, and the phase information related to the RF transmission channel is determined based on the first-order harmonic information.

Abstract: An internal heat exchanger (IHX) assembly for use in a vehicle includes at least three plates joined together to form two or more separate compartments or channels and at least one flat structure on an external surface of the IHX assembly. One compartment or channel contains a high pressure fluid and the other compartment or channel contains a low pressure fluid. The compartment or channel containing the high pressure fluid is in thermal communication with the compartment or channel containing the low pressure fluid, such that heat is transferred from the high pressure fluid to the low pressure fluid. The IHX assembly acts as a structural member in the vehicle upon which one or more refrigerant components are mounted onto the flat structure.

Abstract: A liquid dispenser for cosmetic liquids having a liquid reservoir and an applicator. An outlet channel connects the reservoir to the applicator, the outlet channel being formed either valveless or with an outlet valve. The liquid dispenser has a pressure generating device which pressurizes liquid in the reservoir for conveyance through the outlet channel to the applicator. The pressure generating device has an air pumping device which feeds and an actuating pressure chamber. The actuating pressure chamber adjoins, and is separated from, the reservoir by a displaceable wall so that an overpressure in the actuating pressure chamber leads to an overpressure in the reservoir. The air pumping device has manual actuator, allowing air to be pumped into the actuating pressure chamber by the actuator, so that the overpressure in the actuating pressure chamber and in the reservoir rises sufficiently to convey liquid from the reservoir to the applicator.

Abstract: A discharge head for a liquid dispenser for discharging cosmetic products which has a base to be secured to a liquid storage. The base has a coupling device in the form of a thread or a latching coupling device, for coupling to the liquid storage. The discharge head has a sponge carrier with a sponge receptacle in which a sponge is arranged. The sponge carrier is movable in a translationally guided manner with respect to the base and has a hollow connector inside which a liquid channel is provided that connects the liquid storage to the sponge receptacle. This liquid channel is provided with an outlet valve, which is opened by moving the sponge carrier in the direction of the base, such that liquid can flow freely out of the liquid storage into the sponge receptacle.
