Abstract: A fan washable with water, comprising a wind wheel and a driving motor which are arranged inside the shell; wherein a first partition plate is arranged on the top of the wind wheel; a second partition plate is arranged on the bottom of the wind wheel; and, the first partition plate and the second partition plate are hermetically engaged with the shell.

Abstract: Disclosed are an air-supply assembly and a bladeless fan. The air-supply assembly includes an air-supply frame pillar and an air-supply frame. The air-supply frame pillar is provided with an air-supply frame pillar passage therein, and the air-supply frame is provided with an air-supply passage therein. The air-supply frame pillar is connected to the air-supply frame so that the air-supply frame pillar passage is in communication with the air-supply passage. An air outlet is provided on the air-supply frame.

Abstract: Disclosed are a connection assembly and a fan. The connection assembly includes a base assembly and a post assembly. The base assembly includes a first connection member and a first conductive piece. The post assembly includes a second connection member and a second conductive piece. The first connection member is rotatably connected to the second connection member, the first conductive piece and the second conductive piece are electrically connected after the first and second connection members are rotatably connected.

Abstract: An air conditioning assembly and a bladeless fan are disclosed. The air conditioning assembly includes an air supply assembly. The air supply assembly includes at least two air supply frames. The at least two air supply frames are mated to form an annular air supply surface. Each air supply frame can be rotated independently.

Abstract: The present application relates to a fan washable with water, comprising a wind wheel and a driving motor which are arranged inside the shell; wherein a first partition plate is arranged on the top of the wind wheel; a second partition plate is arranged on the bottom of the wind wheel; and, the first partition plate and the second partition plate are hermetically engaged with the shell.

Abstract: Single loop inductive sensors are widely deployed in infrastructure for traffic data collection, however, these loops currently provide little more than vehicle detection. A system and method are provided that enable single loop inductive sensors to be used for vehicle classification (e.g., identification as motorcycle, passenger car, bus, etc.). Classification may be done using the Federal Highway Administration's 13 class system. Initially a signature library is built from vehicle signatures with known classifications. Vehicle signature waveforms of unknown classification obtained from inductive loop sensors are analyzed to identify specific features in the waveform including the number of “peaks”, the first peak location and its magnitude. A classifier (e.g., K-nearest neighbor) uses a representation of the vehicle signature and the features to determine from the signature library the classification of the vehicle.
