  • Patent number: 12434656
    Abstract: A restraining device of a seat unit protecting a person without relying on a supporting surface. The first part extends from its first end in a first direction over the shoulder of a person sitting in the vehicle seat to a backrest-distal second end being located in front of the person's head and/or torso, and in a second direction from a person-outer third end to a person-inner fourth end. The second part extends in a third direction from a fifth end to a sixth end and from a backrest-proximate seventh end to a backrest-distal eighth end, such that a least an upper section of the second part extends laterally of the person's head. The third part extends in the second direction from a person-outer ninth end to a person-inner tenth end, such that at least an upper section of the third part faces the person's face.

  • 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: 10674401
    Abstract: A data packet comprises a header and a payload. At least one digital signal processor is used to configure the payload to transport 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. 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. At least one digital signal processor is used to configure a single field in the header 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. At least one digital signal processor is used to form the data packet including the configured header and the configured 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: 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.
