Abstract:
Systems for determining a phase of a device coupled to an electrical distribution system. The system includes a number of gateway devices configured to transmit a synchronization signal. The gateway device receives a node response message from a first node device that includes a duration value indicating a time between a receipt of the transmitted synchronization signal and a detected zero crossing. The gateway device compares the duration value against duration values received from node devices with a known phase connection and determines a phase of the first node device based on the comparison.
Abstract:
Low-cost time synchronization associated wireless Battery Management System (BMS) and a host controller are described herein. The time synchronization techniques described herein are low-cost because of the use of existing communicating lines without using adding additional dedicated lines or wires for synchronization. Moreover, the time synchronization techniques described herein may be implemented without complex circuitry.

This disclosure describes systems, methods, and devices related to enhanced fine timing measurement protocol negotiation. A device may identify an enhanced fine timing measurement request received from a first device, the enhanced fine timing measurement request comprising one or more information elements associated with one or more multiple-input multiple-output (MIMO) parameters. The device may cause to send an enhanced fine timing measurement response to the first device. The device may identify a null data packet announcement associated with a location determination of the first device. The device may identify a null data packet received from the first device. The device may cause to send a null data packet feedback to the first device.
Abstract:
Examples herein disclose an identification of a set of skew requirements corresponding to a set of data signals. Based on the set of skew requirements, the examples prioritize an order of transmission for the set of data signals. The example queue the set of data signals in accordance with the prioritized order.
Abstract:
In a logging system (100), multiple receiver units (106) are synchronized over a control area network (CAN) bus (110) without use of separate differential lines. A ready for synchronization command is received over the CAN bus (110). In response to receiving the ready for synchronization command, a start synchronization interrupt is enabled. A start synchronization command is then received over the CAN bus (110). In response to receiving the start synchronization command, the start synchronization interrupt is triggered for capturing formation signals which are produced responsive to excitation signals from a transmitter unit (104).

Abstract:
A rotational synchronizer for metastability resolution is disclosed. A synchronizer includes a plurality of M+1 latches each coupled to receive data through a common data input. The synchronizer further includes a multiplexer having a N inputs each coupled to receive data from an output of a corresponding one of the M+1 latches, and an output, wherein the multiplexer is configured to select one of its inputs to be coupled to the output. A control circuit is configured to cause the multiplexer to sequentially select outputs of the M+1 latches responsive to N successive clock pulses, and further configured to cause the M+1 latches to sequentially latch data received through the common data input.
Abstract:
Techniques for data synchronization between a first computing device coupled to at least one memory storing current data and a second computing device coupled to at least a second memory storing first encoded data and a copy of prior data. The first device may perform a method comprising: encoding the current data using a compressive sensing encoding technique to obtain second encoded data; and transmitting the second encoded data to the second computing device. The second device may perform a method comprising receiving second encoded data from the first computing device; decoding the second encoded data using a compressive sensing decoding technique to obtain decoded data; and obtaining a copy of the current data by using the decoded data and the copy of prior data.
