==RELAY DEVICE, TIME SYNCHRONIZATION SYSTEM, AND PROGRAM - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18031886 titled 'RELAY DEVICE, TIME SYNCHRONIZATION SYSTEM, AND PROGRAM

==Simplified Explanation==

The patent application describes a relay device with the following features:

* The device has an internal clock to indicate time.
* It includes a memory to store information.
* A communication unit is used to transmit and receive signals, including synchronization signals and normal signals, between a master and a slave.
* A retention time processing unit stores synchronization signal information received by the communication unit in the memory.
* The retention time processing unit extracts the synchronization signal information from the memory when a retention setting time longer than a first predetermined time elapses from the reception of the synchronization signal.
* The device's internal clock is used to determine when the retention setting time has elapsed.
* A transmission signal control unit is responsible for controlling the communication unit.
* When the first predetermined time elapses from the reception of the synchronization signal, the transmission signal control unit stops transmitting the normal signal.
* Instead, the transmission signal control unit transmits the synchronization signal, which indicates the synchronization signal information stored in the memory.


==Original Abstract Submitted==

A relay device includes a device internal clock to indicate time; a memory to store information; a communication unit to transmit and receive a signal including a synchronization signal and a normal signal to and from a master and a slave. Further, there is a retention time processing unit to store synchronization signal information indicating the synchronization signal received by the communication unit in the memory and extract the synchronization signal information from the memory when a retention setting time longer than a first predetermined time elapses from the reception of the synchronization signal by using the time indicated by the device internal clock; and a transmission signal control unit to control the communication unit to stop transmitting the normal signal when the first predetermined time elapses from the reception of the synchronization signal and transmit the synchronization signal indicating the synchronization signal information.
