Abstract: A multifunctional catalyst, a method for producing the same, and a method for using the same are provided. The multifunctional catalyst is applicable for recycling a polyester fabric. The multifunctional catalyst includes a carrier, and a first functional ionic liquid and a second functional ionic liquid that are grafted on the carrier. The carrier is an inorganic composite powder material, and is composed of following chemical components: C: Na—Ni/Al2O3. In a process of recycling the polyester fabric, the multifunctional catalyst simultaneously decolorizes and depolymerizes the polyester fabric. The first functional ionic liquid is used to decolorize the polyester fabric, and the second functional ionic liquid is used to depolymerize the polyester fabric.

Abstract: A single smart health device able to monitor all physiological aspects of a human body includes a body fluid detection module, a temperature detection module, an electrocardiogram detection module, and a control module. The body fluid detection module tests and detects amounts of biological substances in body fluids. The temperature detection module detects a temperature of the human body. The electrocardiogram detection module detects a heart rate of the human body. The control module is electrically connected to the body fluid detection module, the temperature detection module, and the electrocardiogram detection module, and obtains the detected amounts of biological substances, the detected temperature, and the detected heart rate.

Abstract: A setting method of in-memory computing simulator includes: performing a plurality of test combinations by an in-memory computing device and recording a plurality of first estimation indices corresponding to the plurality of test combinations respectively, wherein each of the plurality of test combinations includes one of a plurality of neural network models and one of a plurality of datasets, executing a simulator according to the plurality of test combinations by a processing device and recording a plurality of second estimation indices corresponding to the plurality of test combinations respectively, wherein the simulator has a plurality of adjustable settings; calculating a correlation sum according to the plurality of first estimation indices and the plurality of second estimation indices by the processing device, and performing an optimal algorithm to search an optimal parameter in the setting space constructed by the plurality of settings so that the correlation sum is maximal.

Abstract: A voice coil motor held immobile by magnetic attraction when not in use for photography purposes includes a base, a magnet fixed thereto, a carrier, a magnetic member, and a coil. The magnetic member is fixed to the carrier and is attracted by a permanent magnetic field (first MF) of the magnet on the base. The coil is fixed to the carrier and the magnetic member. When the voice coil motor is powered on, the coil generates a second magnetic field (second MF) opposing the first MF. The second MF reduces or eliminates the attractive force of the first MF of the magnet, to separate the carrier and its fittings and allow them to work freely. A lens module and an electronic device are further provided.

Abstract: A convenient self-locking blood pressure cuff facilitating one-handed use by a user taking his own blood pressure includes a cuff belt, a casing assembly, and a self-locking structure. The self-locking structure is received in the casing assembly. The self-locking structure includes a core shaft, a locking assembly, and a pressing assembly. The core shaft is slidably connected to the casing assembly. The locking assembly and the pressing assembly are wrapped around the core shaft. The locking assembly can rotate when a free end of the cuff belt moves with respect to the casing assembly. The locking assembly can further press against the cuff belt when the core shaft slides in the casing assembly. The pressing assembly presses against the locking assembly to prevent the locking assembly from rotating back.
