  • Patent number: 11395184
    Abstract: A receiver receives a data packet with a header and a payload. The payload includes at least one full service data unit, one or two service data unit fragments, or at least one full service data unit and at least one service data unit fragment, where a service data unit fragment is only located (i) at the beginning of the payload or at the end of the payload or (ii) at the beginning of the payload and at the end of the payload. The header includes a single field consisting of a first bit and a second bit, even when a number of full service data units and service data unit fragments in the payload is more than two, the single field indicating whether (i) the payload begins with a fragment of a service data unit and (ii) the payload ends with a service data unit fragment. Digital signal processing circuitry processes the header to determine processing for the payload.

  • Patent number: 10375602
    Abstract: A data packet has a header and a radio link control (RLC) protocol data unit (PDU). The RLC PDU transports at least one full RLC service data unit (SDU), one or two RLC SDU fragments, or at least one full RLC SDU and at least one RLC SDU fragment. An RLC SDU fragment is only located (i) at the beginning or end of the RLC PDU or at the end of the radio link control protocol data or (ii) at the beginning and end of the RLC PDU. A single field in the header consists of a first bit and a second bit, even when a number of full RLC SDUs and RLC SDU fragments in the RLC PDU is more than two. The single field indicates whether (i) the RLC PDU begins with a fragment of a RLC SDU and (ii) the RLC PDU ends with a RLC SDU fragment. The data packet is formed including the configured header and the configured RLC PDU and transmitted.

  • Patent number: 10054540
    Abstract: The invention relates to a device (10) comprising a support (14) having a wave guide (42) allowing the propagation of light of at least one wavelength, generating evanescent waves outwards. According to the invention, the device comprises means for receiving a liquid sample, designed to receive the liquid sample upon contact of the wave guide (42) in such a way as to impregnate the wave guide with a portion of the liquid sample, and actuatable means for breaking the contact between the liquid sample and the wave guide (42).

  • Patent number: 9321425
    Abstract: An airbag includes a first chamber, a second chamber, and a gas flow channel connecting the two chambers. A valve is located inside the gas flow channel allows an unthrottled gas stream from the first chamber to the second chamber when a pressure inside the first chamber is higher than a pressure in the second chamber and blocks or throttles the gas stream through the gas flow channel when the pressure inside the second chamber is higher than in the first chamber. The valve includes a two-layered inlay extending from a first end pointing towards the first chamber to a second end pointing towards the second chamber. The two-layered inlay is connected to the gas flow channel at its first end via at least two connecting points being remote from each other.
