  • Patent number: 10362573
    Abstract: Methods and systems for multi-protocol transmissions in shared spectrum are disclosed. According to principles described herein, a wireless transmitter is configured to generate subcarriers or symbol information from one OFDM technology using subcarriers of another OFDM technology. With this approach, a wireless transmitter configured to transmit OFDM symbols using subcarriers and a subcarrier frequency spacing associated with one OFDM protocol can also be configured to transmit OFDM symbols associated with another OFDM protocol which normally uses different subcarriers and a different subcarrier frequency spacing. In one application, an LTE transmitter uses LTE subcarriers to generate 802.11 (e.g.

  • Patent number: 10246136
    Abstract: An underbody cladding is provided for a two-track motor vehicle with wheel-controlling links as part of a rear axle for cladding the underbody. The underbody cladding at least partially extends in a substantially horizontal plane and extends in the direction of the outside of the vehicle close to an inner side of a rear wheel. The underbody cladding is divided into three sections, a front section, a central section and a rear section. The central section extends at least over a region below the wheel-controlling links and is connected at least over part of the width thereof to the front section and/or the rear section. The central section is designed in such a manner that the section can at least partially follow and/or yield to a vertical movement of the wheel-controlling links. The front and the rear section of the underbody cladding can in each case be arranged in a positionally fixed manner on the motor vehicle and cannot follow and/or yield to a vertical movement of the wheel-controlling links.
