Abstract: A computing device for verifying data integrity is provided, comprising a memory controller configured to receive a plurality of original data blocks. Each original data block has an associated initial CRC value. The memory controller then segments and recombines the received data blocks into logic blocks, and calculates a new logic block CRC value for each logic block. The logic blocks are transmitted with their respective new logic block CRC values to a storage device, and the logic blocks are written to non-volatile memory of the storage device in a write operation. After the write operation, a combined CRC value is calculated for the logic blocks and a combined CRC value for the original data blocks, and compare the combined CRC values. The memory controller determines whether the combined CRC values match. When they match, the memory controller generates a verification response verifying the integrity of the write operation.

Abstract: In a probabilistic amplitude shaping (PAS) system, a distribution matching (DM) component may receive a uniform bit sequence with equal probabilities, which may be converted into symbols with a desired probability distribution (e.g., Gaussian). For example, the probability distribution may use inner constellation points associated with a lower energy and/or power more frequently and outer constellation points associated with a higher energy and/or power less frequently. In general, the DM component may map binary bits to positive amplitudes with a non-uniform distribution according to a DM rate that is based at least in part on a signal-to-noise ratio (SNR), which may vary significantly in a spatial and frequency selective wireless channel. Accordingly, some aspects described herein relate to configuring DM parameters and codeword and resource mappings in a spatial and frequency selective wireless channel.

The quick tripping device further includes a first transmission structure in driving fit with the contact spring and rotatable rotates along with the contact spring. When a short-circuiting current flows through the contact system, the moving contact is repelled by an electric repulsive force between the moving contact and the static contact, so that the moving contact rotates relative to the contact support. The moving contact drives the first transmission structure to rotate through the contact spring, and the first transmission structure drives an operating mechanism to trip.

Abstract: Certain aspects of the present disclosure provide techniques for determining a relay capability configuration for using a control signal to schedule a physical sidelink shared channel (PSSCH) that carries information to organize sidelink connections. The control signal allows user equipments (UEs) to organize a sidelink network absent base station configurations or vendor configurations. For example, the control signal may schedule a discovery signal (DS) associated with a sidelink synchronization signal block (S-SSB). The control signal may be referred to as DS-physical sidelink control channel (DS-PSCCH), different from a normal PSCCH. The DS-PSCCH may have distinct structure and content to allow UEs to organize sidelink networks.
