摘要: Embodiments relate to an aligner breakage solution that tests probability of aligner breakage at weak points. A method includes gathering a digital model representing an aligner for a dental arch of a patient, receiving material property information for a material to be used to manufacture the aligner, and analyzing one or more regions of the aligner. Analyzing a region of the aligner comprises simulating application of a load around the region, determining at least one of a stress, a strain or a strain energy density at the region, evaluating a strength of the aligner at the region, and determining whether the region satisfies a damage criterion based on the strength of the aligner at the region.

摘要: An optical system measures one or more physiological parameters with a wearable device that includes a light emitting diode (LED) source including a driver and a plurality of semiconductor sources that generate an output optical light. One or more lenses deliver a lens output light to tissue of a user. A detection system receives at least a portion of the lens output light reflected from the tissue and generates an output signal having a signal-to-noise ratio. The detection system comprises a plurality of spatially separated detectors and an analog to digital converter. The detection system increases the signal-to-noised ratio by comparing a first signal with the LEDs off to a second signal with the LEDs on. An imaging system including a Bragg reflector is pulsed and has a near infrared wavelength. A beam splitter splits the light into a sample arm and a reference arm to measure time-of-flight.

摘要: Provided is a method for determining origin of carbon source of chemical substance, which makes it possible to determine whether resource-recycled carbon is used as a carbon raw material from a chemical substance in various goods. The method for determining origin of carbon source of chemical substance includes: a step S1 of acquiring a carbon-14 content rate R1 of a standard chemical substance having carbon element in which carbon has been recycled as a resource; a step S2 of acquiring a carbon-14 content rate R2 of a chemical substance to be identified; a step S3 of calculating a ratio (R2/R1) of the content rate R2 to the content rate R1; and a step S4 of determining that a carbon raw material in the chemical substance to be identified contains resource-recycled carbon based on the ratio (R2/R1).

摘要: A power consumption detection system includes a controller, a rubber sampling module, a rubber calender, a temperature control module, a mooney sensor, and a power meter. The rubber sampling module samples a rubber material according to a weight value and obtains a rubber to be tested. The rubber calender continuously calenders the rubber to be tested at least six times. The temperature control module maintains the rubber to be tested with a temperature value. The mooney sensor obtains an actual viscosity index and the controller controls the calendaring number of the rubber calender until the target viscosity index is consistent with the actual viscosity index. The power meter records a power consumed by the rubber calender and obtains a power consumption value.
