  • Patent number: 11551725
    Abstract: There is set forth a method and a system for recording and synchronizing audio and video signals. The audio signal and the video signal are stored together with time stamps from a respective associated system clock. The invention relates to an adaptation of the duration of the recorded audio sequence to the duration of an associated video sequence in order to level out differences in synchronization of the two system clocks. Alignment of the two system clocks is also introduced, which is based on a data transfer which has variable waiting times for the access to a transmission channel. This thus permits clock alignment with means as are available for example on a smartphone.

  • Publication number: 20220386134
    Abstract: A method and a system with which a primary user, in particular a mobile radio operator, can make a part of the radio spectrum range which is reserved exclusively for the mobile radio operator available in localized and/or time-restricted fashion to a local end user who requested the restricted usage authorization of the radio spectrum range using registered credentials at the mobile radio operator. By way of the credentials the mobile radio operator can allow the local end user limited usage of that radio spectrum range in fee-bearing fashion and can bill same. The local user can then use the assigned frequency band in accordance with his own needs. In particular the user can wirelessly transmit signals in the assigned frequency range between end devices to which no credentials are allocated and in that situation use a transmission protocol which is not defined for the mobile radio network.

  • Patent number: 10556551
    Abstract: A carrier device for attachment to a pane of a motor vehicle is disclosed. The carrier device has a base plate which is able to be secured to the pane, on which base plate a carrier arrangement is formed to hold a housing of at least one camera. The carrier arrangement includes at least one holding element having at least one spring element which is designed to apply pressure to a rod-shaped component which is arranged on the housing of the camera and which protrudes beyond a wall of the housing, the pressure acting in the direction towards the second side of the base plate. A pane of a motor vehicle on which such a carrier device is placed is also disclosed.

  • Patent number: 10104147
    Abstract: A method for wirelessly transmitting audio signals based on the Bluetooth protocol from a Bluetooth audio source to a computer device (audio sink). An audio signal is converted in the Bluetooth audio source into an audio data packet. The audio data packets are converted into L2CAP data packets in the Bluetooth audio source based on a protocol with access to the L2CAP layer, and wirelessly transmitted. The Bluetooth audio source suppresses renewed transmission of L2CAP data packets which were erroneous or which were not received by the sink. Real-time transmission or reproduction of the audio stream or the audio signal can thus be effected. The audio stream or an audio signal on the L2CAP layer may be transmitted with a reduced repetition rate in respect of erroneous data packets. Access to RFCOMM or another data transport protocol with access to the L2CAP layer can be provided from the application layer.

  • Patent number: 9994718
    Abstract: The present invention provides a formable hard coating composition, comprising a binder, comprising at least one acrylate oligomer and at least one monofunctional acrylate monomer and a crosslinking agent, comprising at least one multifunctional acrylate or methacrylate monomer. Furthermore, the present invention provides a coated film comprising a coextruded PC/PMMA film and a coating obtained by coating with the hard coating composition, wherein the coating has a dry film thickness according to ASTM B499 in the range of from ?1 to ?6 ?m and preferably a crosslink density in the range of from ?2·10?3 to ?13·10?3. The coated films exhibit a combination of good formability and pencil hardness, solvent and chemical resistance which makes it particular useful for applications such as in-mold decoration processes.

  • Patent number: 9615175
    Abstract: There is provided a method of frequency assignment of wireless radio audio transmission systems having a plurality of wireless transmitters and at least one wireless receiver. The wireless transmitters can represent first wireless transmitters which in the switched-on condition can approach another wireless transmitter below an established minimum spacing and second wireless transmitters which in the switched-on condition cannot approach below the minimum spacing. The wireless transmitters serve for example to transmit an audio signal wirelessly to the at least one wireless receiver. The transmission frequencies of the first wireless transmitters are assigned having regard to possible intermodulation effects. The transmission frequencies of the second wireless transmitters are assigned having regard to the relative spatial distances of the second wireless transmitters relative to each other.
