  • Publication number: 20250311930
    Abstract: One variation of a method for detecting inflammation in a foot includes: accessing a first temperature measured through a left temperature sensor and a second temperature measured through a right temperature sensor at approximately a first time, the left temperature sensor arranged in a left sock and the right temperature sensor arranged in a right sock worn on the user's feet; calculating a baseline difference between the first and second temperatures based on confirmation of absence of inflammation in the user's left and right feet at the first time; accessing a third temperature measured through the left temperature sensor and a fourth temperature measured through the right temperature sensor at approximately a second time; and in response to a second temperature difference—between the third and fourth temperatures—differing from the baseline difference by more than a threshold difference, issuing an alarm through the user interface.

  • Publication number: 20250176836
    Abstract: A system for monitoring a patient includes a garment including a controller and one or more temperature sensors, and a receiving station configured to communicate with the garment over a wireless communication network. The garment may be operable in an inactive mode in which the controller samples the temperature sensors to generate a first set of temperature measurements, and an active mode in which the controller samples the temperature sensors to generate a second set of temperature measurements and the garment communicates the second set of temperature measurements to the receiving station, where the controller transitions the garment from the inactive mode to the active mode based at least in part on the first set of temperature measurements and/or other sensor data such as garment motion data and/or garment orientation data.

  • Publication number: 20250101410
    Abstract: The present disclosure provides a sample extraction device, which includes a plurality of chambers arranged on a pedestal. The chamber includes a plurality of first chambers and two mixing chambers. The pedestal is internally provided with a first passage for communicating the two mixing chambers, and a sample extraction chamber is arranged in the first passage. The pedestal is further internally provided with a second passage for transfer and export of a liquid, and connection or disconnection between the two mixing chambers and the second passage is controlled by a valve. Sample extraction processes of the above technical solutions are carried out in a fully enclosed device, avoiding contamination of samples and extraction reagents by external environments, and avoiding environmental contamination caused by aerosols generated during the sample extraction processes. The sample extraction device is particularly suitable for extraction of highly pathogenic samples.

  • Publication number: 20240207829
    Abstract: The present disclosure relates to a Cu—Zn-SSZ-13 molecular sieve composite catalyst and a preparation method thereof. Firstly, in situ synthesis is conducted by an one-step method and the template agent TMAdaOH is removed. Then a processed diatomite filter aid containing a SSZ-13 molecular sieve seed is added to improve the molecular sieve yield and thus reduce the cost. Finally, the Cu—Zn-SSZ-13 molecular sieve composite catalyst is prepared by substituting ammonium nitrate with ammonium dihydrogen phosphate or diammonium hydrogen phosphate through a counter-ion exchange method. The reaction performance of the catalyst in a temperature range of 100-600° C. is better than that of a SSZ-13 catalyst prepared by an ion exchange method and a Cu-SSZ-13 molecular sieve catalyst prepared by an one-step method, and the yield of the synthetic object is increased by 40%.

  • Patent number: 11561209
    Abstract: A method for simultaneous determination of nitrogen and oxygen isotope compositions of natural nitrate and nitrite, which quantitatively converts natural nitrate and nitrite into an organic ester and a nitro-compounds respectively, and then nitrate and nitrite ?18O and ?15N are simultaneously determined by adopting a gas chromatography/pyrolysis/gas chromatography/isotope ratio mass spectrometry coupling technology (GC/Py/GC/IRMS). According to the method for simultaneously determining the nitrogen and oxygen isotope compositions of the natural nitrate salt and nitrite salt, the small amount of sample does not result in the loss, acquisition, exchange and fractionation of nitrogen and oxygen.
