  • Patent number: 11463489
    Abstract: A real-time collaboration platform can utilize a collaboration application, which is adapted to permit a number of users to communicate with one another in at least one session about a predetermined topic via a network. The real-time collaboration platform can include at least one media server with a selective forwarding unit adapted for selectively forwarding media streams according to a content of a predetermined session. The media server has an interface to a media gateway that is enhanced by a real-time announcement adapter via which interface the media server can be connected to an announcement system with acoustic announcement devices such that the media streams of a predetermined session can be output via the announcement devices.

  • Patent number: 7560835
    Abstract: A primary part of an electrical induction machine, especially a synchronous motor or a linear motor, includes a plurality of modules which each have teeth situated in a row having at least partially encircling slots, in the slot of each tooth a coil is wound around this tooth, and the coils of a single module are connected to a single phase of a rotary current network. The number of modules in the primary part is equal to the number of current phases or an integral multiple thereof. A single module includes an uneven number of teeth but at least three teeth, and teeth directly adjacent to one another of a single module include coils that have an opposite winding direction, which generates an opposite magnetic field polarity at the teeth. An electrical induction machine, especially a synchronous motor or a linear motor, includes a primary part and a secondary part, working together with the primary part via an air gap, which may have permanent magnets as rotor magnets.

  • Publication number: 20090160296
    Abstract: A polyphase electric machine includes a stator impinged by an electromagnetic rotating field, which has a yoke having yoke teeth having at least partially peripheral slots, in which windings generating a magnetic field are situated, and having a rotor rotatable around an axis having permanent magnets, which is peripherally separated from the stator by an air gap, the rotor being fixedly connected to a pulley, the yoke teeth in the stator being assembled into modules, whose number is equal to the current phases or corresponds to their integral multiple, each module including a number of at least one yoke tooth and—in the event of a possible pole pitch of the rotor to slot pitch of the stator ratio of 9/8—yoke teeth of a module directly neighboring one another having opposite magnetic field polarity.
