A communication module may be used in an information handling system comprising an air mover configured to drive a flow of air and a processing component communicatively coupled to the air mover for controlling operation of the air mover via a first wire configured to communicate air mover speed commands from the processing component to the air mover for controlling a speed of the air mover and a second wire configured to communicate tachometer information from the air mover to the processing component. The communication module may include a connector other than an air mover connector configured to couple the air mover to the first and second wire and logic configured to monitor for an escape sequence communicated via first wire from the processing component to enter a command mode and responsive to detecting the escape sequence, communicating information regarding the air mover to the processing component via second wire.

A saddle-type window air conditioner comprises an indoor part, an outdoor part and a connecting part. The connecting part includes an indoor connecting box and an outdoor connecting box sleeved in each other. The indoor connecting box is connected with the indoor part, the outdoor connecting box is connected with the outdoor part, and the connecting part is provided with locking assemblies. Each of the locking assemblies includes a lock sleeve, a lock core, a push button and a rack. The lock sleeve is disposed on the indoor connecting box located on an outer side or on the outdoor connecting box, and is provided with a lock hole; the rack is disposed on the outdoor connecting box located on an inner side or on the indoor connecting box; the push button is connected with the lock core and configured to push the lock core to move; and the lock core is provided with a lock pillar. When the lock pillar is clamped and locked with the lock hole, the lock core is separated from the rack to extend or shorten the connecting part. When the lock pillar is separated from the lock hole, the lock core is clamped with the rack, and the connecting part cannot be extended, but can only be shortened under the action of an external force to realize the locking of the connecting part.

An air conditioner outdoor device isolation structure includes a foot and a vibration isolation member. The foot includes a mounting hole. The vibration isolation member includes a first end part, a connection part, and a second end part connected in sequence, and a connection hole penetrating the first end part, the connection part, and the second end part. The connection part is located in the mounting hole, and the first end part and the second end part are located on opposite sides of the mounting hole.

A reference microphone for detecting noise is located under a first duct. The noise is in the form of a first plane wave in the first duct. A speaker is located on a top of the first duct. Connected to an upper part of the first duct is a second duct including an error microphone. The first plane wave in the first duct passes through an acoustic path and reaches the second duct. The error microphone detects the sound, and the speaker outputs a second plane wave with an opposite phase for canceling the first plane wave.

A method and system for noise cancellation is disclosed. In one embodiment, the method may include receiving, from a first sensor, a first signal indicative of a noise generated by an equipment. The first sensor may be configured to generate the first signal indicative of the noise generated by the equipment. The first sensor may be positioned in proximity to the equipment. The method may further include generating a noise cancellation signal based on the first signal and triggering a speaker to generate a sound corresponding to the noise cancellation signal, wherein the speaker is positioned in proximity to the equipment.

A measuring system includes a temperature-variable container, an optical device and an air conditioner. The temperature-variable container includes a transparent plate. The optical device includes a first optical sensor unit and a second optical sensor unit. The air conditioner is disposed between the transparent plate and the optical device.

A saddle-type window air conditioner comprises an indoor part, an outdoor part and a connecting part. The connecting part includes an indoor connecting box and an outdoor connecting box sleeved in each other. The indoor connecting box is connected with the indoor part, the outdoor connecting box is connected with the outdoor part, and the connecting part is provided with locking assemblies. Each of the locking assemblies includes a lock sleeve, a lock core, a push button and a rack. The lock sleeve is disposed on the indoor connecting box located on an outer side or on the outdoor connecting box, and is provided with a lock hole; the rack is disposed on the outdoor connecting box located on an inner side or on the indoor connecting box; the push button is connected with the lock core and configured to push the lock core to move; and the lock core is provided with a lock pillar. When the lock pillar is clamped and locked with the lock hole, the lock core is separated from the rack to extend or shorten the connecting part. When the lock pillar is separated from the lock hole, the lock core is clamped with the rack, and the connecting part cannot be extended, but can only be shortened under the action of an external force to realize the locking of the connecting part.

An air conditioner includes a cross-flow fan having a cylindrical shape, and a heat exchanger disposed on an upstream side of an air flow of the cross-flow fan. The cross-flow fan includes a plurality of impellers. Each of the impellers includes a plurality of blades arranged in a circumferential direction. The heat exchanger has an inverted V-shape. A clearance is formed between the cross-flow fan and the heat exchanger. The clearance has a dimension no more than 20% of a diameter of each of the impeller. The impellers are arranged with at least one of the blades displaced between each adjacent two of the impellers. A number of the impellers arranged along a rotation axis is at least 14 and no more than 30 in the cross-flow fan. Each of the plurality of impellers being connected together to form a single, continuous unit without a gap disposed between adjacent impellers.
