  • Publication number: 20240036093
    Abstract: An apparatus for measuring characteristics of a capacitor component includes a measurement terminal connected to a capacitor component, an inductor connected to the measurement terminal, and a controller generating characteristic information of the capacitor component based on LC resonance of the capacitor component and the inductor. The controller generates capacitance information of the capacitor component based on inductance, based on at least one of a resonant frequency and an amplitude of the LC resonance and the resonant frequency.

  • Publication number: 20230109627
    Abstract: Provided herein are methods of making a high-quality quantum dot (QD), including by providing anion precursor chemistry that enables chemical modulation of precursor reactivity, thereby, allowing independent optimization of reaction temperature and precursor reactivity to systematically grow high quality QDs and by providing specially configured tunable precursors and related chemistry to facilitate separate reaction pathways for nucleation and growth, thereby accessing heat-up based synthesis of high-quality QD, including core-shell QDs. The methods may include providing a base-QD and a first anion or cation precursor having a composition comprising an anion or a cation element, respectively, and a modification agent. At least one add-layer is grown on the base-QD at a growth temperature, thereby making the high-quality QD comprising the base-QD and the at least one add-layer. At least one add-layer may have a composition comprising an add-layer cation element and an add-layer anion element.

  • Publication number: 20200391169
    Abstract: Provided herein are multiplexible particle systems and related methods of making and using the multiplexible particle systems. A plurality of monodisperse polymer particle populations are provided, wherein each population has a unique electrical parameter for multiplexed detection by flow through a spatially confined electric field, and the distribution of the electrical parameter within each population is sufficiently narrow for reliable multiplex detection. The density difference between populations may be relatively uniform, such as within 30%, including within 30% of a suspending solution density for when the particles are flowed through a confined electric field and detected in a multiplex manner by a change in the electric parameter measured by a counting device. Relatively uniform density of particles is important for ensuring minimal settling while the plurality of particle populations flow together under a single flow regime.

  • Patent number: 10404090
    Abstract: A wireless power transmitting method performed in a wireless power transmitting apparatus includes transmitting a long beacon signal via a transmitting coil; determining whether or not a response signal to the long beacon signal has been received at a wireless communicator; determining whether or not a degree of change in a level of impedance of the transmitting coil is within a reference range responsive to the determination that the response signal is not received; and wirelessly transmitting the power responsive to the determination: that the response signal has been received or that the degree of change is within the reference range.

  • Patent number: 10202546
    Abstract: In this invention, polyimidazole ligands (PILs) incorporating pendant imidazole moieties for nanocrystal binding and either sulfonatebetaine, carboxybetaine, or phosphocholinebetaine moieties for water-solubilization have been developed. Greatly enhanced stability of nanocrystals (both over time and in wide pH range) was achieved by incorporating multi-dentate imidazole moieties which provide strong coordination of the ligand to the nanocrystal surface and prevent aggregation of nanocrystals. Synthesis of betaine PILs was developed by modifying the synthesis of recently developed PEG containing poly imidazole ligands (PEG PILs). These nanocrystals are compact, water soluble, and biocompatible.
