摘要： A semiconductor device is used as one of a plurality of slaves connected in multiple stages to a master and transmits a frame signal output from the master sequentially from a preceding stage to a subsequent stage. The frame signal includes synchronization bits and a message string (for example, command bits, address bits, and guard bits) following the synchronization bits. The semiconductor device includes a logic circuit configured to sample the frame signal at a baud rate corresponding to the synchronization bits and an output stage configured to through-outputs the synchronization bits before sampling without passing them through the logic circuit.

摘要： Provided are a time synchronization method and device, and a storage medium. The method includes that: a synchronized block matching a preset code pattern in a data stream is searched at a SERDES parallel interface; the position of the bit of the synchronized block in the SERDES parallel interface is determined as a first position; a time point when the synchronized block passes through the SERDES parallel interface is determined as a first time point; the synchronized block and a PTP packet in the data stream are searched at an interface between PHY layer and MAC layer, and a distance between the synchronized block and the PTP packet is determined; and a second time point is determined according to the first position, the first time point and the distance, the second time point being the time point when the PTP packet passes through an SERDES serial interface.

摘要： A protocol data bit parsing method and device for an AK protocol wheel speed sensor. The method includes receiving a current signal sent by an AK protocol wheel speed sensor and converting the current signal into a first voltage signal and a second voltage signal; capturing the time of rising edges and falling edges of the first voltage signal and the second voltage signal and saving a first timestamp set and a second timestamp set; acquiring a complete set of timestamps of protocol data bits according to the first timestamp set and the second timestamp set and denoting as protocol data timestamps; and parsing the protocol data bits according to the protocol data timestamps to obtain values of the protocol data bits. The method can reduce the product cost and ensure the safety of the supply chain, which improves the competitiveness of enterprises.

摘要： A process described herein facilitates linking nodes to form a directional network in GPS-denied circumstances. Synchronized nodes wirelessly transmit link establishment requests on pseudo-randomly selected time slots within sub-templates, receive link establishment responses from unsynchronized node on the same time slot in future sub-templates, and transmit link establishment acknowledgements on the same time slot to the unsynchronized node. Upon receipt of the link establishment acknowledgement, the unsynchronized node calculates a clock value to match a clock value of the synchronized node and establishes a link therewith.

摘要： Techniques to secure a time sensitive network are described. An apparatus may establish a data stream between a first device and a second device in a network domain, the network domain includes a plurality of switching nodes, receive messages from the first device by the second device in the network domain, the messages to comprise time information to synchronize a first clock for the first device and a second clock for the second device to a network time for the network domain, update a correction field for a received message with a residence time and time delay value by the second device, determine whether the updated message is benign or malicious, update the correction field for the updated message with an inference time when the updated message is benign, and prevent relay of the updated message to other devices in the network domain when the updated message is malicious.

摘要： This disclosure describes a system for applying precise timing to a mesh wireless Wi-Fi network. The precise timing allows for multiple access points (APs) to serve a single station (STA) when the STA is located in a wireless footprint of more than one access point without the need for a wireless trigger frame. Various examples are described including the use of orthogonal frequency division multiple access (OFDMA), time division multiple access (TDMA) and multi-access point joint transmission.

摘要： In order to provide a transmission device and transmission method with which a response signal for random access preamble transmitted from a preamble transmission device is efficiently transmitted, setting unit in base station sets a first resource candidate group, which enables terminal capable of receiving a latch response transmitted by demodulation reference signal (DMRS) transmission to be selected, and a second resource candidate group, which enables terminal incapable of receiving a latch response transmitted by DMRS transmission but capable of receiving a latch response transmitted by cell-specific reference signal (CRS) transmission to be selected. Control unit selects DMRS transmission as the latch response transmission method when a resource in which latch preamble has been received is included in the first candidate group, but selects CRS transmission as the latch response transmission method when the resource is included in the second resource candidate group.

摘要： In one implementation, a method comprises: receiving, in a first radio, a radio frequency (RF) signal and processing the RF signal to provide a bit stream to a digital circuit of the first radio; enabling a first correlator of the first radio to detect at least a first portion of a sync word of a wake-up packet of the bit stream, and thereafter enabling a second correlator of the first radio to detect at least a second portion of the sync word; enabling an averager circuit to detect another portion of the sync word; and in response to detection of the sync word, disabling the first and second correlators and maintaining the averager circuit enabled.

摘要： A subscriber station for a serial bus system. The subscriber station has a communication control device for controlling a communication of the subscriber station with at least one other subscriber station of the bus system. The communication control device generates a transmit signal according to a frame and inserts a field having an edge into the frame after a second communication phase. The field has, before the edge, a predetermined length corresponding to a time period that is longer than the time period of a bit time of a first communication phase. The edge is provided for synchronization to the communication on the bus for a communication control device of the at least one other subscriber station of the bus system whose transceiver device is switched, before the predetermined time period, into an operating mode for transmitting and receiving the frame in the first communication phase.
