Abstract: A set of sensors is disposed beside a cylinder to collect a first set of temperature points. The first set of temperature points is updated and distributed on a coordinate plane corresponding to a length and rotation degrees of the cylinder. The coordinate plane is segmented along a horizontal axis with a fixed length to define a rectangular area, and a second set of temperature points is distributed on the rectangular area. The second set of temperature points is a subset of the first set of temperature points. On the rectangular area, the second set of temperature points is clustered into n sets of temperature points using a k means algorithm. A notification signal is sent according to an xth set of temperature points of the n sets of temperature points. The xth set of temperature points has a highest mean temperature among the n sets of temperature points.

Abstract: A derailleur apparatus for bicycles includes a housing on a handle and a gearshift control assembly inside the housing. The gearshift control assembly has a first lever for cable-pulling, a ratchet assembly having a ratchet plate further having teeth, a second lever for cable-releasing, and an index claw.

The derailleur apparatus is characterized on that: the index claw further has a matching member and a second pawl, the second lever and the matching member form a first specific contact and a specific actuation relationship, and the second lever can move arbitrarily. While the second lever moves to form a second specific contact with the matching member, the index claw rotates to mesh the second pawl with the ratchet plate, such that the down-shift movement toward a second direction can be performed.

Abstract: A motherboard error detection system includes a pluggable error detection board and a motherboard having a boot management chip. When the motherboard enters a device-driven status from a standby status, the boot management chip is used to manage power-on timings of different voltage sources; to collect a plurality of sets of status information; and to check whether the sets of status information and the power-on timings have errors. The pluggable error detection board includes an interpreting unit, a message-reading interface and a connector which is pluggably disposed on the motherboard. When the boot management chip notifies the pluggable error detection board to read an error message, the interpreting unit converts the error message to human-readable information, and the human-readable information is outputted through the message-reading interface.
