An electronic device is provided, including a processor, a graphics processing unit, a first temperature sensor, a second temperature sensor, an embedded controller and a memory. The first temperature sensor detects the temperature of the processor. The second temperature sensor detects the temperature of the graphics processing unit. The embedded controller increases the current fan speed according to a temperature change of the processor, a temperature change of the graphics processing unit, and/or a change of an operating state of the graphics processing unit. When the temperature of the processor rises to a first predetermined value, the temperature of the graphics processing unit is raised and the operating state of the graphics processing unit is changed, and the embedded controller increases the current fan speed according to a first speed table corresponding to the graphics processing unit stored in the memory.

An optical detection device and a detection method thereof are provided. A linear light source provides a light curtain formed by multiple light beams, the light curtain is located on a transportation path of transporting an object to be detected. A sensor set senses the part of light beams not interrupted by the object to be detected, so as to generate a sensing signal with various strengths. A control circuit determines a physical characteristic, moving speed and position of the object to be detected according to the strength of the sensing signal.

A mower slope sensing system on a grass mowing machine. An elevation sensor may capture terrain elevation values for each of a plurality of different locations according to a latitude and a longitude of each of the locations on a field. An electronic controller may store the terrain elevation values, latitudes and longitudes, and adjust a mowing blade speed depending on changes in the terrain elevation values from a current location to a next expected location.

One embodiment of a method of controlling low-speed propulsion of a marine vessel includes receiving user input to engage an automatic speed control mode and then, when the automatic speed control mode is engaged, receiving the user input indicating at least one of a selected lure identifier and a selected fish identifier. A desired speed parameter is then determined based on the selected lure identifier and/or the selected fish identifier. The propulsion device is then controlled to automatically maintain the desired speed parameter.

A contact control device (100) includes a disturbance correction timing control unit (42) that selectively outputs a first reference speed signal indicating a first reference speed or a second reference speed signal indicating a second reference speed lower than the first reference speed. When a movable part (12) comes closer to a second component (B) beyond a first reference position between a fixed part (11) and the second component (B), the disturbance correction timing control unit (42) switches its output signal from the first reference speed signal to the second reference speed signal and switches a gain in proportional compensation from a first gain to a second gain lower than the first gain.
