An angular velocity detection device includes an angular velocity sensor configured to detect angular velocity, an acquisition unit configured to acquire orientation information in a three-dimensional space on a moving object including the angular velocity sensor, a calculation unit configured to calculate estimated angular velocity based on the acquired orientation information, and a correction unit configured to correct an output of the angular velocity sensor based on the angular velocity detected by the angular velocity sensor and the estimated angular velocity calculated by the calculation unit.

The techniques disclosed herein provide improvements over existing systems by dynamically controlling communication connections between two or more computing devices based on the detection of specific events. Instead of requiring a device, such as an IoT device, to be continually connected to a network or a remote device, the techniques disclosed herein enable the device to remain offline until a specific event is detected. The disclosed technologies can avoid always-on network configurations while providing a desired functionality for an IoT device. For instance, some devices only connect with other computing devices or at network in response to detection of an event, then disconnect after an exchange of specific information. Such technologies can significantly reduce the power consumption of a device by only invoking connections at appropriate times.

An optical axis control apparatus is provided with a relative-road-surface-angle calculating unit which calculates a relative horizontal plane angle being an inclination angle of a vehicle with respect to a horizontal plane by using an output value of an acceleration sensor provided on the vehicle and calculates a relative road surface angle being an inclination angle of the vehicle with respect to a road surface by integrating an amount of change of the relative horizontal plane angle while the vehicle is stationary, a relative-road-surface-angle correcting unit which obtains braking information indicating an operation state of a brake device provided on the vehicle and corrects the relative road surface angle for a change in the braking information, and an optical axis control unit which controls an optical axis of headlights provided on the vehicle using the relative road surface angle corrected by the relative-road-surface-angle correcting unit.

A method of recognizing obstacles on operation of a vibratory pile driver of a work machine includes monitoring an acceleration signal of the vibratory pile driver during operation of the vibratory pile operator and analyzing the acceleration signal to determine the presence of an obstacle. The acceleration signal may be monitored over a time period which is determined based on an excitation frequency of the vibratory pile driver. The analysis may include comparing negative and positive half-waves of the acceleration signal. Responsive to the analysis indicating an obstacle, a system operator may be alerted, and/or operation of the vibratory pile driver may be adjusted via controller intervention.

A system for detecting the operational status of a seed-planting implement. The system includes a row unit including a frame and a residue removal device coupled to the frame. The residue removal device is configured to remove residue from a path of the row unit. The system further includes a sensor configured to capture data indicative of at least one of a position or an acceleration of the residue removal device. The system further includes a controller configured to monitor the data received from the sensor and compare at least one monitored value associated with the at least one of the position or the acceleration of the residue removal device to a predetermined threshold value set for the residue removal device. The controller is further configured to identify the residue removal device as being plugged when the at least one monitored value differs from the predetermined threshold value.

A cooling device of an internal combustion engine includes a control valve that regulates the flow of a cooling liquid in a circulation circuit, and an electronic control unit. The electronic control unit is configured to have the following functions: controlling driving of a motor of the control valve; determining whether or not the shifting speed of a valve body of the control valve has decreased rapidly; calculating a motor torque based on an effective voltage applied to the motor; deriving a collision factor based on a smoothed angular speed value; and when the electronic control unit determines that the shifting speed of the valve body has decreased rapidly, calculating a rapid-decrease-caused stress so as to become larger as a product of the motor torque and the collision factor becomes larger.
