Abstract: For online audio/video conferencing applications deployed in an open office environment, using shared conference devices, it can be advantageous to define an acoustic fence. A non-participant audio received from outside the acoustic fence can be considered noise and filtered out before transmission of an audio signal to a far end recipient. Three suppression stages are used to filter the non-participant audio. The first suppression stage uses beamformers for suppression. The second suppression stage is mask-based, and the third suppression stage is reference-based. The three suppression stages filter out non-participant audio signals, having a wide range of frequencies.

Abstract: A cooking device includes a lower heating plate unit, an upper housing member, and at least one positioning mechanism that includes a lower coupling unit fixed to the lower heating plate unit, an upper coupling member fixed to the upper housing member, an actuating member disposed on the upper coupling member, and a pin connected to the upper coupling member. The cooking device further includes an upper heating plate coupled to the upper housing member. Removal of the upper heating plate results in the actuating member being pushed resiliently to have a positioning portion thereof engaging a guiding hole of the lower coupling unit, so that the upper housing member is limited to move to be parallel to and spaced apart from the lower heating plate unit.

Abstract: System and method for gas pressure stabilization. The system comprises a pressure stabilizer which is divided into a receiving chamber and a pressure chamber by a flexible membrane, a booster device, a gas divider, and a control driver that can sense movement of the flexible membrane and control the gas divider accordingly. A pressure pilot is used to set the desired pressure in the pressure chamber. The pressure of the receiving chamber will stabilize to be the same with that of the pressure chamber regardless of the gas flow change or gas pressure change at the gas source, or the pressure fluctuation in the downstream system. The gas passing the system can eventually be recycled to a recycling system in the downstream without harming the environment.
