摘要:
A discharge device having an actuating handle, a first pump system for conveying a first medium and a second pump system for conveying a second medium. The actuating handle can be moved between an initial position and an end position. The first pump system includes a first pump chamber and a first piston arranged in a displaceable manner in the first pump chamber. The second pump system includes a second pump chamber and a second piston arranged in a displaceable manner in the second pump chamber. The first piston and the second piston can be displaced via the actuating handle in the direction of actuation, and the actuating handle and the first piston are coupled to each other such that the actuating handle and the first piston can be displaced relative to each other in a direction of actuation via a free travel.

An apparatus for determining information on a power variation of a transmit signal comprises a power amplifier module, an antenna module and a power variation determining module. The power amplifier module amplifies a radio frequency transmit signal and the antenna module transmits at least partly the amplified radio frequency transmit signal. The power variation determining module determines a weighted sum of a first feedback signal derived from the amplified radio frequency transmit signal and a second feedback signal derived from the amplified radio frequency transmit signal. The first feedback signal and the second feedback signal comprise different dependencies on a varying impedance at the antenna module. Further, the power variation determining module generates a power variation signal based on the weighted sum. The power variation signal comprises information related to a power variation of the amplified radio frequency transmit signal.

A system for controlling amplifier power is provided. The system includes a voltage envelope detector that receives a voltage signal and generates a voltage envelope signal. A current envelope detector receives a current signal and generates a current envelope signal. A power amplifier level controller receives the greater of the voltage envelope signal and the current envelope signal, such as by connecting the output of the voltage envelope detector and the current envelope detector at a common point and conducting the high frequency current components to ground via a capacitor. A power amplifier level control signal is then generated based on the voltage drop across the capacitor.

A dispenser system including a storage container a medium, having an outlet valve, a dispenser module having a medium chamber, a pumping device that is actuated to discharge medium from the medium chamber and having an inlet valve, and an actuating device. The medium chamber is a sealed chamber having a variable volume, and the dispenser module is coupled to the storage container to fill the medium chamber. During filling, the inlet valve and the outlet valve are opened such that the medium chamber communicates with the storage container. The actuating device has a magnet and a magnetic or magnetizable element interacting therewith for a volume change of the medium chamber. The actuating device causes a volume of the medium chamber to be enlarged to produce a differential pressure between the medium chamber and the storage container to convey medium out of the storage container into the medium chamber.

摘要:
A dispenser system including a first dispenser module having a medium chamber fillable with medium, a first discharge head actuable for discharging medium from the medium chamber, a refilling opening, and a second dispenser module coupleable to the first dispenser module for refilling the latter. The second dispenser module has a storage container for medium, and a second discharge head. In the decoupled state of the dispenser modules, the second discharge head is actuable for discharging the medium out of the storage container and has a discharge opening. The second discharge head has a ventilation system for equalizing the pressure in the storage container when the medium is discharged. The dispenser system has an air pump system. In the coupled state of the dispenser modules, the air pump system is fluidly coupled to the ventilation system and conveys air via the ventilation system into the storage container.
