Abstract: A system may include a first acoustic event detection (AED) component configured to detect a predetermined set of acoustic events, and include a second AED component configured to detect custom acoustic events that a user configures a device to detect. The first and second AED components are configured to perform task-specific processing, and may receive as input the same acoustic feature data corresponding to audio data that potentially represents occurrence of one or more events. Based on processing by the first and second AED components, a device may output data indicating that one or more acoustic events occurred, where the acoustic events may be a predetermined acoustic event and/or a custom acoustic event.

Abstract: A heating system for compressed parts capable of controlling process atmosphere and pressure includes an accommodating body, a heating device, an atmosphere controlling device, and a processing pressure adjusting device. The heating device is disposed inside or outside of the accommodating body to heat a component to be heated, so as to remove an impurity within the component to be heated. The atmosphere controlling device transports a reaction gas, such as hydrogen, oxygen, water vapor, or plasma, into a cavity for reacting with the impurity within the component to be heated. A phase transition or a chemical reaction can be carried out, such that the impurity is gasified, oxidized, carbonized, or disintegrated. The processing pressure adjusting device uses an inert gas (e.g., a nitrogen gas or an argon gas) to control the processing pressure in the cavity to be from 800 Torr to 10?2 Torr.

Abstract: A diffusion furnace in the shape of polygonal-prism, including two end frame plates arranged in opposite basal planes of the diffusion furnace and a plurality of heating panels connected between the two end frame plates. Each heating panel includes at least one beam connected between the two end frame plates and a plurality of heating block interconnected in succession along and secured to the respective beam. Each heating block includes a block body, at least one heating element arranged on one side of the block body and amounting assembly mounted on the opposite side of the block body for securing the heating element. Thus, the disclosed diffusion furnace can be customized to satisfy different measurements requirement and can be easily decomposed for repair.

Abstract: A roller sealing device arranged at an access port of a continuous furnace for adapting a continuous processed planar processed material. The rolling device includes a pair of first roller carriers arranged correspondingly opposite to each other, each having a first roller assembly. Each first roller carrier includes a first sealing roller and two first auxiliary rollers; the first sealing roller and two first auxiliary rollers are pivoted to a respective one of the first roller carriers; the two first auxiliary rollers are located between the first sealing roller and the corresponding first roller carrier. The first auxiliary rollers rollingly abut against the first sealing roller and the corresponding first roller carrier. Therefore, the roller sealing device is sealed well so as to prevent the gas from leakage. The present invention further provides a gas-sealing method.

Abstract: A diffusion furnace is disclosed, which includes an outer housing, an inner housing, and a plurality of infrared heating elements. The inner housing is arranged within the outer housing, and a chamber is formed inside of the inner housing. A portion of each infrared heating element is arranged on the outer housing. Each of the infrared heating elements has a heating portion and at least one fixing portion connected thereto. The heating portion of each infrared heating element is arranged within the outer housing. The fixing portion of each infrared heating element is secured onto the outer housing. Therefore, the heating elements would neither distort nor have any issues in staying secured to the furnace. Moreover, the furnace can be cooled down more quickly after operation.

Abstract: A heating device with a function of dynamical temperature-control includes an oven housing, a door, at least one air-discharge device and a plurality of heaters. The oven housing has a plurality of walls, and the walls define a chamber. The door is pivoted disposed on the oven housing. The air-discharge device and the heaters are disposed on the oven housing. The heaters are respectively dynamical-adjustable and independent-operating heating elements to achieve the uniformity of chamber temperature.

Abstract: A heat-insulating sealing device is mountable between a bottom face of an openable top cover and a top face of a furnace bottom of a heating furnace which defines a furnace chamber. The heat-insulating sealing device includes outer and inner looped sealing strips adapted to surround the furnace chamber and adapted to provide a seal between the top cover and the furnace bottom. The outer looped sealing strip extends around the inner looped sealing strip, is made of a heat-resistant resilient polymeric material, and is adapted to be disposed distal from the furnace chamber. The inner looped sealing strip abuts against an inner side of the outer looped sealing strip, is adapted to extend around the furnace chamber, and includes a heat-resistant fabric.
