Abstract: A quantitative pooled-sample testing method and apparatus for chemical test items of consumer products are provided. The test method includes: calculating a maximum number of samples that can be pooled according to parameters such as regulatory limit requirements, measurement uncertainty, the number of pooled samples, a sample pooling ratio, and the like; establishing a searchable table according to a relationship between a qualified rate, the number of samples that can be pooled, and reduced workload; for various items to be tested, directly querying the table to acquire reduced workloads corresponding to different numbers of samples that can be pooled; and when the number of samples that can be pooled does not exceed a maximum value and corresponds to the most greatly reduced workload, determining that number of samples that can be pooled as an optimum number of samples that can be pooled, and performing pooled-sample testing.

Abstract: Provided is a terminal device, which includes: a light-emitting layer and a cover plate, camera unit; the light-emitting layer includes a first light-emitting layer and a second light-emitting layer; when the first light-emitting layer is located at a first preset position, a first orthographic projection area of the first light-emitting layer in a first direction coincides with a second orthographic projection area of the camera unit, wherein the first direction a direction pointing from the light-emitting layer to the cover plate; and when the first light-emitting layer is located at a second preset position, a third orthographic projection area of the light-emitting layer does not coincide with at least part of the second orthographic projection area.

Abstract: A method and a system of alerting and/or monitoring patient with sleep disorder includes: a detector for detecting a change in a first parameter, a storage device, a control unit for deciding if the change meets a set criteria, and if the change meets the set criteria, saving the first parameter and/or time in the storage device, a feedback unit for adjusting the set criteria according to sleep behavior of the patient, and an alarm device for sending an alarm, wherein the first parameter includes sound, motion, heart rate, blood pressure, breathing frequency, magnitude and/or frequency of movement, muscle activity, brain activity, eye movements, heart rhythm, heart rate variability, blood oxygen levels, breathing pattern, and/or body position.

Abstract: An ultrasonic extraction performance checking device and method for an ultrasonic extractor for detecting and analyzing a chemical composition of a consumer product. The ultrasonic extraction performance checking device includes a hanging frame which is hung inside the ultrasonic extractor and matched with the ultrasonic extractor, and a hanging frame plane checking device which is detachably and vertically or horizontally placed in the hanging frame and clamped with an alloy foil. The alloy foil is surrounded by a tensioning fixture. The tensioning fixture causes the alloy foil to generate a surface tension of 5 to 15 N and to be tightened and fixed to the bottom surface of the hanging frame plane checking device.
