摘要： A system or a board that interacts with a processor and multi I/O devices such as high-speed facsimile modems. The processor inputs/outputs data to I/O devices. Each I/O device includes an indicator, such as an Interrupt Request output, to signify a request that the I/O device will output or input data. If the indicator signifies a request, the processor will input data from or output data to the I/O device within a predetermined period Ti, in order to prevent the data from being lost. To this end, the new system or board includes a timer that periodically interrupts the processor and causes it to execute an interrupt service at a period T, where T

摘要： A system for the detection, recording, and analysis of EMG data attained during exercise in real-time is described. The system employs a surface EMG sensor equipped with a Bluetooth or a Wi-Fi module. The sensor transmits sEMG data via Bluetooth or Wi-Fi to a smart device, which processes this data utilizing a preloaded application and informs the user of the efficacy of exercises with key statistics in real-time. A sensor box containing the EMG sensor also contains a pre-amplification circuit, an amplification circuit, a DC-offset circuit, and a signal smoothing and amplifier circuit to maximize the reduction of extraneous noise frequently observed with conventional sEMG sensors. A proprietary mobile device application receives, interprets, records, and displays the EMG data for the user.

摘要： This invention relates to a visible-light-responsive photocatalyst for photocatalyticly oxidation desulphurization and method for preparation and application thereof. The catalyst is comprised of one type of metal MI, one type of metal oxide MIIOx and BiVO4 as the supporter, wherein the mass ratio of the sum of the two types of metal (MI+MII) to BiVO4 is from 1:5000 to 1:50; the mass ratio of the type of metal MI to the type of metal MII is from 1:50 to 50:1. The catalyst is used in the photocatalytic oxidation desulphurization. Under mild condition (room temperature, 1 atm), using O2 as the oxidant and xenon lamp (wavelength 420 nm

摘要翻译： 本发明涉及一种用于光催化氧化脱硫的可见光响应光催化剂及其制备及应用方法。 催化剂由一种金属MI，一种金属氧化物MIIO x和BiVO 4作为载体组成，其中两种金属（MI + MII）与BiVO4之和的质量比为1:5000至1 ：50; 金属MI的类型与金属MII的类型的质量比为1:50至50:1。 该催化剂用于光催化氧化脱硫。 在温和条件（室温，1大气压）下，使用O2作为氧化剂，氙气灯（波长420nm <λ<700nm）作为光源，避免油吸收光（主要在低于420的紫色区域 nm），噻吩的脱硫率可以达到90％以上，同时油不会被激发。 噻吩中的硫可以被氧化成SO3，并在从反应体系中逸出后被吸收剂吸收。 因此，可以节省常规氧化脱硫的提取，降低运行成本。 与紫外光响应光催化剂相比，可见光响应光催化剂可广泛用于油中。 我们可以通过沉降或离心来恢复反应后的光催化剂。
