    摘要: The present invention relates to a ball picking robot, comprising a walking mechanism, a ball picking mechanism, a ball pushing mechanism and a ball storage mechanism. The ball picking mechanism comprises a ball picking basket, an air cylinder used for driving the ball picking basket to move up and down, an air storage tank used for providing an air source for the air cylinder, a solenoid valve arranged at the air outlet of the air storage tank, a micro air pump connected to the air storage tank, and a shielding assembly arranged at an opening in the rear end of the ball picking basket. A first gear is mounted at the input end of the micro air pump. The ball pushing mechanism comprises a rotary ball discharging assembly, comprising an either-rotation motor, a rotary impeller connected to a first output shaft of the either-rotation motor through a belt assembly.

    摘要: A transmitting device may identify a set of bit locations of a polar code for encoding an input vector based at least in part on a reliability order of the bit locations, where the input vector includes a set of payload bits. The transmitting device may map bits of the input vector to respective bit locations of the identified set of bit locations and may apply a masking operation to a subset of bits of the input vector that is mapped to a most reliable subset of the set of bit locations. The transmitting device may perform an encoding operation according to the mapped input vector to generate a codeword for transmission. A receiving device may perform complementary operations to obtain the payload bits of the input vector. Based on the described techniques, a false alarm rate for the receiving device may be suppressed.

    摘要: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support hybrid automatic repeat request (HARQ) schemes to improve the likelihood that information is received correctly over a wireless communications link. In HARQ, when a transmitting device determines that a receiving device failed to successfully decode a transmission of information, the transmitting device may retransmit the information to the receiving device. In some cases, HARQ techniques may be used for communications associated with different types of services. In such cases, to keep the latency of communications within a latency budget for a particular type of service, wireless devices may utilize the techniques described herein to dynamically terminate HARQ retransmissions. For instance, a transmitting device may avoid retransmitting information when an amount of time that has elapsed since an original transmission of the information has exceeded the latency budget.
