  • Patent number: 9762003
    Abstract: The invention relates to a network connector assembly for vehicles. The network communicates at data rates of 100 Mbit/s and/or 1 Gbit/s. The connector assembly includes a header having at least two pins forming a pin pair. The pins extend in a mating direction. The connector assembly also includes an electrically conductive shielding member shielding the pin pair on at least two sides. The shielding member has a front face that is oriented substantially normal to the mating direction. The connector assembly further includes a header shroud, wherein the header shroud is provided with a shielding cavity for receiving the shielding member. The front face of the shielding member is at least partly covered by the header shroud.

  • Publication number: 20160205453
    Abstract: The present invention relates to an external speaker/microphone apparatus for use with an electrical device for providing audio signals and/or for voice communication. The apparatus comprises: one or more speakers and one or more microphones; and a housing that encloses the one or more speakers and the one or more microphones. The shape of the housing is formed from a number of twelve or more flat surfaces. Through the use of a housing, the shape of which is formed from a number of twelve or more flat surfaces, a more flexible orientation of the external speaker/microphone apparatus—and therewith of the one or more speakers and the one or more microphones to the user(s)—is made possible. At the same time, the use of flat surfaces allows for a sufficient stableness.

  • Patent number: 7490037
    Abstract: The invention concerns a method of encoding signals, in particular digitized audio signals, with an encoding device for encoding the signal in an encoding format and a processing device for processing the encoded signal. Methods of that kind are known for example from European patent specification No 290 581. In that case, in the bit rate-reducing encoding of audio signals which are already present in digitized form, for example 48 kHz sampling frequency/16-bit resolution, psycho-acoustic phenomena of the perception of audio signals are used in such a way that the original bit rate of the audio signals is considerably reduced. Such methods are also familiar and standardised under the heading of ‘source encoding’ (ISO 11172 and 11318). The object of the invention is to provide a method of the kind set forth in the opening part of this specification, which resolves the above-indicated problems and in which re-coding operations, once encoding has been effected, are very substantially avoided.

  • Patent number: 7190693
    Abstract: A method and apparatus for transferring/receiving audio and/or video signals for bridging synchronous and asynchronous networks and minimizing delay time over such networks including analysing the active network interface for determining the network interface that is receiving and/or sending data, taking a multiplexed synchronous-clock signal from the network and providing it to a bitstream analyser, analysing the format of a multiplexed signal obtained from another audio codec, analysing the audio format, adapting the ISDN network clock to the IP network clock for forming a clock-adapted digital signal, encoding the digital signal, adapting the encoded signal to IP datagrams, and, inserting the datagram signal in the IP network.

  • Publication number: 20060083169
    Abstract: A method and system for transferring/receiving audio and/or video signals and minimizing delay time over Internet networks including, in transmission, converting, analog audio and/or video input signal to digital form by means of an A/D converter, processing the digital audio and/or video signal in order to manipulate, control, adapt or change it, converting the sampling rate of the digital audio and/or video signal for adapting the digital input clock to the network clock or for adapting the A/D clock to the network clock resulting in an clock-adapted digital signal, encoding the clock-adapted digital signal for reducing the number of bits resulting in a lower bit rate encoded signal, multiplexing the encoded signal and packing it into a resulting multiplexed signal which needs to comply with the used and/or applied network interface, inserting the multiplexed signal into a network, and analysing the active network interface for deterimining the network interface that is receiving and/or sending data; and in

    Abstract: The invention concerns a method of encoding signals, in particular digitised audio signals, with an encoding device for encoding the signal in an encoding format and a processing device for processing the encoded signal.

  • Patent number: 5991715
    Abstract: A method of transmitting digitized block coded audio signals includes forming scale factors of the digitized audio signals. The n(k-1) differences are formed from k successively in-time scale factors for each frequency sub-band or for a group of spectral values of the audio signal. The n(k-1) differences are grouped into at least two value classes. New scale factors are selected for each of the n sub-bands or spectral value groups based on a sequence of n(k-1) value classes. Identifying information, including the control information indicating at which locations in the sequence of n(k-1) value classes the selected new scale factors are disposed, is associated with each sequence of n(k-1) value classes. The associated selected new scale factors are assigned to each sequence of the sampled signal values and to the identifying information associated with each sequence of sampled signal values.

  • Patent number: 5740317
    Abstract: Source coding digitized audio signals includes providing time or spectral domain sampling values of the digitized audio signal, requantizing the sampling values according their permissible quantizing noise as determined by a coding and requantizing control signal, and multiplexing the control signal and the requantized sampling values into a time multiplex frame depending on the bit rate reduction employed. The coding and requantizing control signal is determined from the sampling values by determining the global masking effect from all relevant maskers which are tonal maskers and noise maskers, and which result from the sampling values, and from a silence audio threshold.

  • Patent number: 5659660
    Abstract: A method of encoding an audio signal for transmission and/or for storage includes changing a digitized audio signal based on a selected signal changing criteria. The changed digitized audio signal is encoded, based at least on an available data rate for transmitting and/or storing the audio signal, for reducing an amount of data associated with the changed, digitized audio signal. The reduced-data audio signal is then evaluated for determining whether a code overload condition exists. If a code overload condition exists, another signal changing criteria is selected. A time behavior and/or a spectral distribution of the digitized audio signal is recursively changed based on the another signal changing criteria before the amount of data associated with the digitized audio signal is reduced so that deterioration of reduced-data audio signal is not perceptible when the coded signal is decoded.

  • Patent number: 5440584
    Abstract: Digitalized encoded audio signals for transmission over disturbed channels are composed of a series of information blocks made of information units containing various types of information, such as control information, scale factor information and information on encoded scanning values derived from partial-band and/or transformation coding at the source. The units of information concerning the encoded scanning values are allocated to a predetermined spectral structure. Before its transmission or storage, the encoded audio signal is subjected to a channel encoding dependent on the desired error protection. When errors are recognized, they are corrected, and when the errors cannot be corrected, they are concealed. For the channel encoding of the units of information concerning the encoded scanning values, a variable bit error protection is provided depending on the allocation of the individual information unit to a determined spectral structure, i.e.
