Abstract: The present disclosure provides a taxonomy-based diagnostic system and method, and a readable storage medium.

Abstract: A device for measuring a parameter indicative of a rotational speed of a component includes a wired or wireless input configured to receive a vibration signal from a vibration sensor, a boost filter configured to filter the vibration signal, based on a predetermined frequency range, into a sinusoidal signal and, a comparator configured to generate a pulse waveform signal from the sinusoidal signal in order to read the value of the parameter. Also a motor or pump controller including the device.

Abstract: A vehicle chassis health evaluation method and apparatus is disclosed. The method for health evaluation of vehicle chassis may include monitoring the vibration of at least one of the wheel end and the reducer by a vibration sensor. The vibration sensor is installed in the wheel end and/or the reducer. The method may further include, based on the monitored vibration of at least one of the wheel end and the reducer, performing the health evaluation of the vehicle chassis. The health evaluation method of the vehicle chassis of the present disclosure allows the real-time state of the vehicle chassis to be determined, even when the vehicle is driving, and critical safety accidents caused by the chassis can be avoided.

Abstract: A method and a system for automatic diagnosis of equipment, and a non-volatile processor-readable storage medium storing program instructions for performing the method. The method includes: acquiring a signal associated with operation of the equipment; processing the acquired signal based on automatic diagnosis domain knowledge to extract feature data associated with a current operating state of the equipment, wherein the automatic diagnosis domain knowledge represents data related to a failure mechanism of the equipment; and identifying whether the equipment has an abnormal operating condition based on a similarity between the extracted feature data and historical data associated with a normal operating state of the equipment.

Abstract: A train speed estimation device and method are disclosed. Vibration in a natural frequency band experienced by a train as it advances is sampled by means of first and second sensors at the same sampling frequency, to obtain a first set and a second set of sampling signals respectively; a first set and a second set of vibration signals are obtained on the basis of the first set and second set of sampling signals respectively, and the first set and second set of vibration signals are subjected to cross-correlation analysis, to obtain a target sampling difference; and a train speed is calculated on the basis of the target sampling difference. The train speed estimation device and method according to the present disclosure can precisely monitor the real-time train speed without relying on any speed sensor or GNSS.

Abstract: A docking station is configured to receive media in the form of audio and/or video from a portable entertainment device. The docking station transmits the received media to a remote playing device via a wired, wireless, or powerline connection. The media may include a control signal associated with the audio and/or video to control the remote playing device. In certain embodiments, the remote playing device transmits control signals to the docking station to control the portable entertainment device. In certain embodiments, the docking station electrically charges the portable entertainment device.

Abstract: An apparatus for conducting fluid in a fuel cell. The apparatus includes a unitary gas-impermeable body having, a face having a recessed surface and a wall extending around the recessed surface, the recessed surface and the wall defining a fluid dispersion area. The apparatus further includes a plurality of spaced apart protrusions protruding from the recessed surface in the fluid dispersion area such that portions of the recessed surface extend all around each of the protrusions, each protrusion having a protrusion surface spaced apart from the recessed surface. The apparatus further includes an inlet opening, an inlet conduit, an outlet opening and an outlet conduit.
