  • Patent number: 12247589
    Abstract: A hydraulic system for a rotary implement, including an oil tank, a main pump, a control valve, and a rotary motor is provided. The oil tank is connected to an oil suction port of the main pump; an oil outlet of the main pump is connected to a P port of the control valve; a T port of the control valve is interconnected with the oil tank; and A and B ports of the control valve are connected to both ends of the rotary motor. The control valve includes a compensation valve connected to the P port and the T port, an electric proportional valve connected to the P port and the compensation valve, and an electromagnetic reversing valve connected to the compensation valve, the T port and the B port.

  • Publication number: 20230116980
    Abstract: A seat adjusting structure includes a seat body. A damping force unit is installed at an upper end of the seat body, and a cab connecting plate is installed at a lower end of the seat body. An electronic controller and a seat weight sensor are installed between the damping force unit and the cab connecting plate. A rigidity unit and an operator presence indicator are installed at a lower part of the damping force unit, and a seat damper is installed above the cab connecting plate. The operator presence indicator detects whether an operator exists, while the seat weight sensor detects whether the weight of the operator is within a set range. The electronic controller receives detection signals from the operator presence indicator and the seat weight sensor and controls the damping force unit and the rigidity unit to adjust the rigidity and damping force of the seat damper.

  • Patent number: 11196445
    Abstract: A method including determining a cyclic redundancy check (CRC) generator sequence defining a one to one mapping between a sequence of control information values and cyclic redundancy check (CRC) sequence values; and determining a combined sequence, the combined sequence formed by distributing the cyclic redundancy check (CRC) value sequence within the sequence of control information values, wherein the distributing the cyclic redundancy check (CRC) value sequence within the sequence of control information values is based on a selected part of the cyclic redundancy check (CRC) generator sequence.

  • Patent number: 11165536
    Abstract: A method for encoding a sequence of control information bits comprising: generating a sequence of error detection bits based on the sequence of control information bits; generating a sequence of error correction bits based on the sequence of control information bits; and distributing the sequence of error detection bits and the sequence of error correction bits between the sequence of control information bits to form a combined sequence of bits, such that the bit order of the combined sequence of bits following the distribution enables an error detection check to be performed before or after a first error correction check bit.

  • Patent number: 10979084
    Abstract: A base matrix is applied to an LDPC coder. The base matrix includes multiple parts, each including multiple of rows and columns, and containing integers, each representative of an identity matrix cyclically shifted in accordance with the integer or representative of an all-zero matrix. At least two of the multiple parts are configured such that their respective column-wise combinations of rows represents a same starting vector, cyclically shifted or interleaved, with zero or more but not all integers not indicative of the all-zero matrix of the same vector substituted by integers indicative of the all-zero matrix. The at least two of the multiple parts are not identical. The applied base matrix is used for one of encoding data using the LDPC coder or decoding data using the LDPC coder.
