OIL DETERIORATION DIAGNOSIS DEVICE
Provided is an oil deterioration diagnosis device capable of detecting oil deterioration accurately and early in real time during operation of an operating machine without oil sampling. An oil deterioration diagnosis device 10 for a construction machine including an oil hydraulic circuit 1 includes: a floodlight projector 11a configured to irradiate oil flowing through the oil hydraulic circuit 1 with measuring light having a predetermined wave number or wavelength during operation of the construction machine; a photoreceiver 11b configured to receive transmitted light having penetrated the oil; a signal processing unit 11c configured to continuously or intermittently measure absorbance or transmittance; and a diagnosis unit 12 configured to detect a decrease of an antioxidant contained in the oil or an increase of a peroxide contained in the oil, based on changes in the absorbance or the transmittance.
DISASTER COUNTERMEASURE SUPPORT SERVER, DISASTER COUNTERMEASURE SUPPORT SYSTEM, AND DISASTER COUNTERMEASURE SUPPORT METHOD
The possibility of a work machine 40 being affected by a disaster in a second designated area including an existence position of the work machine 40 is predicted based on an amount of rainfall in a first designated area. A hazard map representing a result of the prediction of the possibility of the work machine 40 being affected by a disaster in the second designated area is outputted to a remote output interface 220 in a remote operation apparatus 20 (a client) (or a management output interface 620 in a management client 60). Accordingly, a user can take measures to reduce the possibility of the work machine being affected by a disaster, for example, to communicate with the persons involved in order to move the work machine 40 from a current position.
WORK MACHINE AND REMOTE CONTROL SYSTEM FOR WORK MACHINE
A work machine includes: a vehicle body; a first imaging device that is disposed in the vehicle body and images a first imaging range; a second imaging device that is disposed in the vehicle body and images a second imaging range; and a communication device that transmits a first image in the first imaging range and a second image in the second imaging range to a remote place. At least a part of the second imaging range is set below the first imaging range.

OPERATION SUPPORT SERVER, OPERATION SUPPORT SYSTEM, AND OPERATION SUPPORT METHOD
There is provided a technique capable of appropriately controlling a warm-up completion timing of a work machine in view of scheduled use of the work machine. A warm-up period elapsed until a measurement value of an internal state variable satisfies a designated condition, i.e., warm-up is completed since a warm-up operation of a work machine 40 was started is predicted based on a measurement value of an external state variable with an operation of the work machine 40 stopped. The warm-up operation of the work machine 40 is started at a first designated time t1 as an appropriate timing based on the predicted warm-up period such that the measurement value of the internal state variable of the work machine 40 satisfies the designated condition by a second designated time t2.

Pipe-laying system and method
A pipe-laying system and method includes assessing an environment and placing of a pipe from an excavator to a trench. The system comprises a frame, a boom assembly, and an implement. The boom assembly includes a large boom and a dipper stick. The implement is detachable coupled to the dipper stick and moveable relative to the dipper stick. The system also includes at least one sensor operable to sense a position or a direction of movement of the large boom, dipper stick, or implement. The system also includes a stereo camera to obtain visual data. A controller is adapted to receive the visual data signal, identify an edge of the pipe, receive a signal from the sensor, associate the visual data with corresponding data, create visual feedback and an input signal the position of the boom assembly.
Control system for work vehicle, method for setting trajectory of work implement, and work vehicle
A control system for the work vehicle includes a display, an input device, and a controller. The controller displays a current position of a work vehicle on a screen of a display. The controller receives a first input signal indicating an input operation by an operator from a input device. The controller determines, as a first position, the position of the work vehicle when the first input signal is received. The controller displays the first position on the screen of the display. The controller receives a second input signal indicating an input operation by an operator from the input device. The controller determines, as the second position, the position of the work vehicle when the second input signal is received. The controller determines a target design surface indicating a target trajectory of a work implement based on reference position information including at least the first position and the second position.
AUTOMATIC VEHICLE SPEED CONTROL SYSTEM
An automatic vehicle speed control system for use in a vehicle having an implement is disclosed. The automatic vehicle speed control system includes: a controller configured to: set a speed of the vehicle to a creep setting; monitor one or more operating conditions of the implement; and automatically adjust the speed of the vehicle based on the one or more operating conditions of the implement.
