A cleaning device is provided, which includes a spray cleaning system, a sewage suction system, an air-drying system, and a conversion valve. The spray cleaning system includes a first pathway, a clean water tank, a first pump, and a cleaning component; the sewage suction system includes a second pathway, the cleaning component, a second pump, and a sewage tank. The second pump is configured to drive sewage to be sucked in by the cleaning component and collected in the sewage tank; the air-drying system includes a third pathway, the cleaning component, and the second pump, the second pump is configured to drive airflow into the cleaning component through the third pathway; and includes an inlet end and an outlet end. The present disclosure enables the device to switch between sewage suction and air-drying functions simply and conveniently by designing the conversion valve.

The present disclosure relates to air fryer, comprising a main body, the main body is provided with a first cooking cavity and a second cooking cavity arranged at intervals up and down. By arranging the first cooking cavity and the second cooking cavity in the main body at intervals up and down, not only can two types of food be cooked simultaneously to improve food cooking efficiency, but also the lateral volume of the air fryer can be reduced, the space occupancy of the air fryer can be lowered, and the space utilization rate can be improved. Meanwhile, the two cooking cavities are hermetically isolated, which can also avoid the interference between the air intake and air outlet of the first cooking cavity and the second cooking cavity, effectively improve the thermal circulation efficiency in the first cooking cavity and the second cooking cavity, thereby enhancing the cooking efficiency and effectively improving the user experience.

Provided are an edge computing apparatus and a system for synchronizing multimodal data based on human factors intelligence. Behaviors and/or voices of the test subject can be recognized through the AI module, the event marking information is issued when the recognition result is matched with the target behavior and/or the target voice, so that the test subjects can accurately trigger the event marking as long as they perform a predefined target behavior or make a preset target voice when receiving stimulation such as vision, olfaction, avoiding the inaccuracy of test analysis caused by the artificially triggered event marking by the personnel implementing an experiment, effectively improving the objectivity of event marking, thus helping to accurately analyze the impacts of stimulus events on the multimodal data.

Provided are a method and an apparatus for detecting personnel's stress state based on human factors intelligence, an electronic device and medium. The method includes: obtaining a PPG signal of a test subject, where the PPG signal of the test subject includes first resting-state data and to-be-tested-state data; performing data slicing on the first resting-state data and the to-be-tested-state data respectively to obtain corresponding first segment data and second segment data, where a length of the first segment data is greater than a length of the second segment data; inputting the first segment data and the second segment data into a trained personnel stress state detection model for prediction to obtain a first EDA prediction result; and determining a stress state of the test subject based on the first EDA prediction result.

A capacity expansion method for a household food waste disposer includes a detecting step in which after activating a treatment routine, a control unit continuously detects the temperature and relative humidity at a temperature and humidity detection point by a detection element installed at the temperature and humidity detection point and a determination and reminder step in which the control unit calculates and determines whether the detected temperature rise rate is higher than a predetermined threshold, and if the temperature rise rate is not higher than the threshold, users are reminded by an audio-visual reminder to open a lid and add food waste to the disposal drum again, and the control unit continues to run the treatment routine when the lid is closed. In this way, the present disclosure can expand the capacity of the household food waste disposer to more than three times its actual physical capacity.

A method for determining a drying of a food waste disposer contains steps of: saving a comparison table of a pressure temperature of a saturated water vapor in a control unit of the food waste disposer; starting drying process; and calculating. The method further contains a step of judging automatically, after calculating the current target humidity value U_b, the control unit compares the current relative humidity U₁ with the current target humidity value U_b and automatically determines a drying status of the food waste disposer and controls a working status of the drying device based on a comparison result.

A liquid perfume having three layers and three colors comprises a perfume liquor having an upper layer, a middle layer and a lower layer; the upper layer is an oil phase layer comprising an oil phase solvent and an upper-layer pigment which are dissolved into each other; the middle layer is a water phase layer comprising middle-layer deionized water, a middle-layer water phase solvent and a middle-layer pigment which are dissolved into each other; the lower layer is a water phase layer comprising lower-layer deionized water, a lower-layer water phase solvent, a lower-layer pigment and salts which are dissolved into each other ; the upper-layer, the middle-layer and the lower-layer each have one kind of different color due to their respective layer pigments ; at least one of the upper layer, the middle layer and the lower layer has an essence. Thus, the whole liquid perfume has rich visual effects with three colors and three layers and emits fragrance, and can satisfy the consumers' diversified needs. The present invention also discloses a manufacturing method thereof.

Provided are a method and an apparatus for removing individual differences in physiological signals, an edge computing device, and a storage medium. The method includes: acquiring physiological signals of a plurality of subjects, where the physiological signals are acquired by a physiological signal acquisition device when the plurality of subjects perform a same task; extracting frequency domain features based on the physiological signals, where the frequency domain features are configured to characterize frequency characteristics of the physiological signals; extracting cepstral features based on the frequency domain features; and normalizing the cepstral features to obtain cepstral features of the physiological signals with at least part of individual differences among the plurality of subjects removed. The method according to the present disclosure is beneficial to normalizing physiological signals, and removing individual differences in the physiological signals without restricting the data distribution of physiological signals, thereby having a wider range of applications.
