  • Patent number: 11597038
    Abstract: A welding structure includes: a first metal member and a second metal member that are superimposed and welded together. The first metal member has a hole. The second metal member includes a nugget portion where a part of the second metal member has been melted by heat of laser light and has re-solidified. A peripheral portion of the hole in the first metal member covers the nugget portion. A part of the nugget portion is exposed through the hole.

  • Patent number: 10819389
    Abstract: The disclosure describes embodiments for reducing adjacent channel interference for wireless vehicular messages. In some embodiments, a method includes monitoring, by an onboard vehicle computer, a channel of a Vehicle-to-Everything (V2X) radio for a V2X message. The method includes determining waveform data describing a waveform that is measured on the channel by the onboard vehicle computer when monitoring the channel. The method includes determining interference data which describes an adjacent channel interference waveform which is measured on the channel by the onboard vehicle computer when monitoring the channel. The waveform includes the adjacent channel interference waveform.

  • Patent number: 10491312
    Abstract: The disclosure describes embodiments for reducing interference for wireless vehicular messages. In some embodiments, a method includes detecting a presence of an interference signal on a channel of a Vehicle-to-Everything (V2X) radio which obscures payload data that is included in a V2X message received via the channel. The method includes determining a source of the interference signal present on the channel. The method includes canceling out the interference signal from the V2X message using a cancellation sequence selected based on the source to generate a modified version of the V2X message including the payload data which is substantially unobscured by the interference signal. The method includes providing the modified version of the V2X message to a vehicle component so that the vehicle component provides its functionality based on the payload data and not the interference signal.

  • Patent number: 9447441
    Abstract: A polyhydroxyalkanoate copolymer of 3HB (3-hydroxybutyrate), 3HP (3-hydroxypropionate) and 5HV (5 -hydroxyvalerate) disclosed. The polyhydroxyalkanoate can be used for bioplastic or biomaterial. A method for producing the polyhydroxyalkanoate comprises culturing a microorganism belonging to Ralstonia genus in a culture medium that comprises lactone and/or hydroxy acid or salt of hydroxy acid as a carbon source.

  • Patent number: 9270024
    Abstract: A PDMA terminal (1000) establishes communication by forming a plurality of spatial paths to another single radio apparatus. A plurality of antennas constituting an array antenna are divided into a plurality of subarrays corresponding to the plurality of spatial paths respectively. An adaptive array processing unit (USP) can perform an adaptive array processing for each of the plurality of subarrays. A memory (MMU) stores in advance information on the number of antennas associated with the number of spatial paths that can be formed by the array antenna. A control unit (CNP) controls a processing to transmit possible multiplicity information to another radio apparatus at a prescribed timing.

  • Patent number: 9204463
    Abstract: An RF unit and a modem unit receive a packet signal, containing information regarding a frame construction, which is transmitted from a base station apparatus in a first period of a frame at least including first periods and second periods. An extraction unit identifies the second period in the frame, based on the received packet signal. A setting unit sets a waiting time period in the identified second period. A carrier sensing unit carries out carrier sensing over the waiting time period set by the setting unit. The modem unit and the RF unit broadcast the packet signal based on a result of the carrier sensing.
