  • Patent number: 12235668
    Abstract: A method, apparatus, system and computer program is provided for controlling an electric power system, including implementation of a voltage control and conservation (VCC) system used to optimally control the independent voltage and capacitor banks using a linear optimization methodology to minimize the losses in the EEDCS and the EUS. An energy validation process system (EVP) is provided which is used to document the savings of the VCC and an EPP is used to optimize improvements to the EEDCS for continuously improving the energy losses in the EEDS. The EVP system measures the improvement in the EEDS a result of operating the VCC system in the “ON” state determining the level of energy conservation achieved by the VCC system. In addition the VCC system monitors pattern recognition events and compares them to the report-by-exception data to detect HVL events.

  • Publication number: 20240342397
    Abstract: The disclosed tamper-evident closure encloses a medical access device, such as a vascular access device, such that it will be visibly apparent if the medical access device contained in the tamper-evident closure becomes exposed. The tamper-evident closure cannot be reapplied over the medical access device in a way to look the same as it did prior to exposing the medical access device. The tamper-evident closures comprise a securing strap with a first securing strap portion secured to the first part of the tamper-evident closure, a second securing strap portion with a free end for securing to a second part of the tamper-evident closure, and an area of weakness separating the first securing strap portion from the second securing strap portion. The force to break the area of weakness is less than the force to separate the securing strap from the first part or second part.

  • Publication number: 20240309373
    Abstract: The invention provides specific synthetic chimeric xenonucleic acid guide RNA; s(XNA-gRNA) for enhancing crispr mediated genome editing efficiency. The invention also provides methods and compositions for inducing CRISPR/Cas-based gene editing/regulation (e.g., genome editing or gene expression) of a target nucleic acid (e.g., target DNA or target RNA) in a cell. The methods include using single guide RNAs (sgRNAs) that have been chemically modified with xeno nucleic acids which enhance gene regulation of the target nucleic acid in a primary cell for use in ex vivo therapy or in a cell in a subject for use in in vivo therapy. Additionally, provided herein are methods for preventing or treating a genetic disease in a subject by administering a sufficient amount of a sgRNA that has been chemically modified with xeno nucleic acids to correct a mutation in a target gene associated with the genetic disease.
