  • Publication number: 20240044070
    Abstract: A method of making an antimicrobial textile comprising TiO2 nanoparticles is described. The TiO2 nanoparticles are immobilized by first treating a textile with a base, and then contacting with TiO2 nanoparticles in a solution of an alcohol and acid. The textile may be subsequently irradiated with UV light prior to use. The antimicrobial textile shows high effectiveness against the growth and proliferation of microorganisms transmitted within indoor environments.

  • Patent number: 11781885
    Abstract: An energy-efficient capacitance-to-digital converter (CDC) is provided that utilizes a capacitance-domain successive approximation (SAR) technique. Unlike SAR analog-to-digital converters (ADCs), analysis shows that for SAR CDCs, the comparator offset voltage will result in signal-dependent and parasitic-dependent conversion errors, which necessitates an op-amp-based implementation. The inverter-based SAR CDC contemplated herein provides robust, energy-efficient, and fast operation. The inverter-based SAR CDC may include a hybrid coarse-fine programmable capacitor array. The design of example embodiments is insensitive to analog references, and thus achieves very low temperature sensitivity without the need for calibration. Moreover, this design achieves improved energy efficiency.

  • Patent number: 8709788
    Abstract: Characteristics of a chemical or biological sample are detected using an approach involving light detection. According to an example embodiment of the present invention, an assaying arrangement including a light detector is adapted to detect light from a sample, such as a biological material. A signal corresponding to the detected light is used to characterize the sample, for example, by detecting a light-related property thereof. In one implementation, the assaying arrangement includes integrated circuitry having a light detector and a programmable processor, with the light detector generating a signal corresponding to the light and sending the signal to the processor. The processor provides an output corresponding to the signal and indicative of a characteristic of the sample.
