  • Patent number: 10313276
    Abstract: It is presented a method for managing a jitter buffer depth for receiving real-time communication. The method is performed in a receiver and comprises the steps of: determining an adaptive bitrate state of the receiver when a current capacity of a communication channel for receiving the real-time communication is below a maximum bitrate for receiving the real-time communication; and increasing a depth of a jitter buffer for receiving the real-time communication when the adaptive bitrate state is determined.

  • Patent number: 10309926
    Abstract: The present invention relates to a device for controlling movement of a fluid sample along a flow path and a corresponding method. The device comprises a working electrode (2) arranged to contact the fluid sample when the fluid sample moves along the flow path, and a reference electrode (3) arranged to contact the fluid sample when the fluid sample moves along the flow path. At least a portion of the reference electrode is arranged abreast of or downstream at least a portion of the working electrode. The present invention is advantageous in that it provides a device wherein a fluid sample may be transported and accurately controlled, with respect to e.g. timing, volumes and flow rates, over greater distances compared to prior art.

  • Patent number: 9584759
    Abstract: There is provided determination of a bit rate request (BRR) for a multimedia encoder of an electronic device. First bit rate information is received from a receiver of multimedia content. The multimedia content is generated by the multimedia encoder and transmitted by the electronic device on a transmission link of the electronic device to the receiver. The first bit rate information is related to the transmission link. Second bit rate information relating to a reception link of the electronic device is acquired. A set of properties of the transmission link and the reception link is determined. A combined BRR is determined for the multimedia encoder as a function of the first bit rate information and the second bit rate information, wherein the function depends on the set of properties. The combined BRR is provided to the multimedia encoder.

  • Patent number: 8472320
    Abstract: A method of controlling an adaptable jitter buffer in accordance with the present invention detects a context description of data handled by the adaptable jitter buffer. Thereafter it is determined whether the detected context description is equal to a predetermined context description. If not, jitter buffer adaptation proceeds as normal. Otherwise it is determined whether the current target buffer depth is too low for the detected context description. If not, the target buffer depth is frozen to the current value. Otherwise it is increased and frozen at a higher value that is compatible with the detected context description.

  • Patent number: 7450601
    Abstract: A method for controlling a jitter buffer and a communication apparatus implementing the method and functioning as a first node of a communication system, wherein the jitter butter is adapted to buffer a stream of blocks of compressed speech information generated in a second node in the communication system, transmitted to and received in the first node. Blocks of compressed speech information in said stream of blocks are selected (201) according to a predetermined rule based on the current buffering delay of the jitter buffer and at least one characteristic of said blocks of compressed speech information. Predetermined actions aiming at reducing buffering delay in the jitter butter are applied (202) to the selected blocks.

  • Patent number: 7444281
    Abstract: A method for generating speech packets and a communication apparatus implementing the method and functioning as a first node of a communication system. A first stream of digital speech samples having a first sample rate is provided (201). If the first sample rate is determined (202) as not matching a required sample rate, said speech packets are generated (204) based on a second stream of digital speech samples generated (203) by performing sample rate conversion of the first stream of digital speech samples.

  • Patent number: 7328038
    Abstract: In a radio communication system in a mobile to mobile call with one good (AMR102) and bad (AMR515) radio link, the good radio (AMR102) link is forced by the poor (AMR515) link to use a more robust AMR coded mode (AMR515) and thereby using excessive power (232). A capacity loss in such system is avoided by adjusting the power level (212) for the connection with the good link (AMR102).

  • Patent number: 7036529
    Abstract: An arrangement for mixing a first and a second gas flow, for example, an inlet flow with a exhaust gas return flow in a diesel engine, comprising a line (16) for the first flow, an inlet (7) for the second flow in the line (16), in order to achieve the mixing; a streamlined body (8) arranged to be displaced in the longitudinal direction of the line (16) at the inlet (7) in order to achieve a variable venturi effect and in this way a variable suction effect and mixture of the mixed flow; and actuating means for displacing the body forwards and backwards in the line. In order to minimise the need for throttling and the accompanying pressure losses, the streamlined body (8) and the supply part (2) are designed to achieve maximal throttling in the line (16) close to the inlet (7), independently of the position of the body.

  • Patent number: 6539010
    Abstract: A radiocommunication method and system which facilitates half-rate communications as well as downlink power control and selective beam transmission is described. Data associated with two terminals is multiplexed into a single timeslot. A first terminal's data occupies a first portion of the timeslot, while the second terminal's data occupies a second portion of the timeslot. A synchronization/training field may separate the first and second portions of the timeslot. In this way, a base station can change the power level and/or direction of transmission of the different terminal's data even though that data is multiplexed together on the same timeslot.
