Abstract: A first reception processing unit performs a process of receiving a first signal transmitted on a first transmission line, a second reception processing unit performs a process of receiving a second signal transmitted on a second transmission line, and an output speed control unit controls output speeds of the first signal and the second signal subjected to the reception process. A system switching unit selects and outputs the first signal or the second signal subjected to a reception process, and an output processing unit performs a process for output to another apparatus on the output from the system switching unit. A reception side clock output unit outputs a clock signal giving a processing timing of each process, and a clock frequency control unit adjusts a frequency of the clock signal giving the processing timing to the output processing unit.

Abstract: A transmission apparatus includes redundant first communication devices configured to communicate with a communication apparatus provided in a first network, and redundant second communication devices configured to communicate with a communication apparatus provided in a second network. The second communication devices include respective first ends that are ends of redundant communication paths of the first communication devices, and the first communication devices include respective second ends that are ends of redundant communication paths of the second communication devices.

Abstract: An informing device is an informing device mounted on a work vehicle that includes a lower base body, and a swivel body swivelably provided at the lower base body. The informing device includes a first detection unit that detects the actual amount of rotation of a drive device which swivels the swivel body or a driven part driven by the drive device, and a notification unit that issues a notification regarding information corresponding to the amount of rotation detected by the first detection unit.

Abstract: An auger attachment system for an extendable boom having a first stage, and a second stage, the auger attachment system having a fixed mounting configured to couple to an auger, the fixed mounting being coupled to the second stage of the extendable boom, an extendable mounting, configured to couple to the auger, the extendable mounting being coupled to the first stage of the extendable boom, and a linear actuator configured to extend and retract the extendable mounting to transfer the auger from the extendable mounting to the fixed mounting.
