The present invention relates to the operating principle of a loudspeaker () with an induction motor (). The motor () has two magnets (and) positioned on either side of a central core (). The magnets (and) thus create two magnetic fields (and) doubling the magnetic field detected in the movable armature (). The magnetic field coupled to the electrical field generated by a fixed coil () creates a force in the armature (), which is linked to diaphragm () producing the sound. Thus, by increasing the magnetic field, and therefore the force generated in the armature (), the performances of the loudspeaker () are likewise enhanced.

The present invention relates to principles for cooling the stationary winding of an induction motor, said winding being positioned outside the movable armature. The cooling can be achieved by means of cooling fins, openings allowing the ventilation of the winding with or without a fan, a fluid circuit outside the bowl, a fluid circuit inside the bowl, a fluid circuit inside the winding, and/or the addition of heat pipes inside the bowl. This motor as presented can be used, without limitation, inside loudspeakers or vibrators.

System for cooling the stationary winding of an induction motor

The invention relates to a device () for preparing a beverage, more particularly, for a vehicle comprising: —a brewing unit () for receiving a dose () of beverage ingredients, —a pressure pump () for supplying pressurized liquid to the brewing unit, —an electronic control unit () for selectively controlling the activation of the pressure pump, wherein the electronic control unit () is arranged to control the activation and deactivation of the pressure pump (), by providing output to the pressure pump as response to input indicative of a determined inclination angle relative to horizontal and/or to a detected spatial displacement or acceleration; said input being received from inclination angle and/or displacement sensing means () which are part of and/or foreign to the device.

Beverage preparation device for vehicle

Beverage preparation device () for preparing a beverage from a beverage dose () comprising: &#x2014;a brewing unit () for receiving the dose () and preparing a beverage from the ingredients contained within the dose and pressurized liquid injected in the dose, &#x2014;a pressure pump () for supplying pressurized liquid to the brewing unit (), &#x2014;beverage dispensing means () connected to the brewing unit and comprising a beverage injector () arranged for dispensing the beverage through a bottom () of a beverage receptacle (); wherein the beverage dispensing means () comprises a residual beverage draining valve (), between the beverage injector () and the brewing unit (), which is arranged to be moved between a beverage dispensing position and a residual beverage draining position, wherein the residual beverage draining valve () and/or the beverage receptacle () comprise valve activation means () arranged to move the draining valve between a beverage dispensing position in response to the engagement of the bottom of the receptacle with the beverage injector and a residual beverage draining position in response to the removal of receptacle from the beverage injector ().
