  • Publication number: 20230417279
    Abstract: A tapered roller bearing having a diameter of less than 1.5 m includes an inner ring having at least one inner raceway, an outer ring having at least one outer raceway and at least one set of tapered rollers between the inner ring and the outer ring that are configured to roll on the at least one inner raceway and on the at least one outer raceway about a tapered-roller rotational axis while the tapered roller bearing is configured to rotate about a bearing rotational axis. An angle formed by the bearing rotational axis and the tapered-roller rotational axis is greater than 450 and is preferably between 500 and 55°.

  • Patent number: 11657829
    Abstract: A communication system with a noise cancellation (NC) assembly providing adaptive or dynamic noise cancellation. The NC assembly includes a localizer module determining, during a communication session (active speaking or during idle times), a location of the active talker. The NC assembly includes a beam generator forming a beam in the determined direction of the active talker to enhance the active talker speech. Once the NC assembly has determined the position of the active talker, the NC assembly assigns a microphone of the microphone array or generated beam in that active direction to be the “active signal” source. The NC assembly assigns a second microphone or beam to be the noise source for NC purposes, and this source may be selected to be in acoustic shadow of the first microphone used as the active signal source or may be the farthest away in its position from the active talker's position.

  • Patent number: 11655854
    Abstract: A rolling-element bearing assembly includes a first bearing ring and a second bearing ring that define a bearing interior between them, a plurality of rolling elements disposed in the bearing interior to allow a relative rotation of first and second bearing rings, and a seal assembly for sealing the bearing interior. The seal assembly includes a seal carrier that is connected to the first bearing ring such that they rotate together and a seal element that is connected to the seal carrier such that they rotate together, and the seal carrier comprises a fiber-reinforced plastic.

  • Patent number: 10848201
    Abstract: A cloud based echo canceller is set forth for recreating an estimate of a lost packet or data at a server without requiring redundant data over the network or freezing operation of the echo canceller. In an exemplary embodiment, the echo cancelling function is not located in a single device, but is shared between the end-point and a cloud service, where the function of the end-point is to provide a time synchronized copy of the signal from the end-point loudspeaker and the signal received by the end-point microphone. Consequently, the high CPU intensive operations can be offloaded to a server such as a cloud server. In addition, several users can share the echo canceller, thereby reducing the cost of the overall function. According to an additional aspect, a further synchronization block is provided, in the form of a packet estimator, to compensate for packet or data loss in the send direction.

  • Patent number: 9544702
    Abstract: Technology for dynamic characterization of a communication device is disclosed. One method comprises sending an acoustic characterization excitation signal to be output by an acoustic transducer in the communication device. A received acoustic coupling signal that is received by a microphone of the communication device in response to the output of the acoustic transducer is measured. An acoustic signal conditioning algorithm is applied to at least one of the microphone or the acoustic transducer to reduce an amplitude of the acoustic signal or the received acoustic coupling signal to a level below a selected threshold.
