  • Publication number: 20240085941
    Abstract: An impedance measurement circuit and an operating method thereof are provided. The impedance measurement circuit includes a current source, a voltage controlled oscillator (VCO), an operation circuit, and a first delay circuit. The current source, electrically connected to a power rail, is able to sink a current from the power rail according to the delayed clock signal. The VCO is configured to generate an oscillation signal according to a power voltage on the power rail. The operation circuit is electrically connected to the VCO and is configured to receive a sampling clock signal and the oscillation signal, sense the power voltage to generate a sampled signal, and accumulate the sampled signal to generate a measurement result. The first delay circuit, electrically connected to the current source and the operation circuit, is able to receive the sampling clock signal and transmit the delayed clock signal to the current source.

  • Publication number: 20210361670
    Abstract: Biocompatible microparticles include an ophthalmically active cyclic lipid component and a biodegradable polymer that is effective, when placed into the subconjunctival space, in facilitating release of the cyclic lipid component into the anterior and posterior segments of an eye for an extended period of time. The cyclic lipid component can be associated with a biodegradable polymer matrix, such as a matrix of a two biodegradable polymers. Or, the cyclic lipid component can be encapsulated by the polymeric component. The present microparticles include oil-in-water emulsified microparticles. The subconjunctivally administered microparticles can be used to treat or to reduce at least one symptom of an ocular condition, such as glaucoma or age related macular degeneration.
