  • Patent number: 11805801
    Abstract: Devices, systems, and methods for real-time peeling are disclosed. Peeling can include including evaluating and controlling one or more peelers to remove peel from organic materials. Evaluation can be performed by an evaluation system including a convolutional neural network to determine a peel value. Control can be performed by a machine learning model on the basis of the peel value. Control can include determination of real-time settings for peeler tool speed and/or gate position.

  • Patent number: 11786662
    Abstract: An autoinjector is described that includes an outer body, a first trigger, an output needle, and a first compartment. The first compartment is positioned within the outer body and includes (i) a main body, (ii) a first biasing member coupled to the first trigger, and (iii) a protrusion positioned at a distal end of the main body. The autoinjector further includes a second compartment positioned in the outer body and in fluid communication with the first compartment and the output needle. The autoinjector also includes a second biasing member coupled to a second trigger. The first biasing member is configured to, upon application of force to the first trigger, automatically move an ampule in a distal direction relative to the main body to force the ampule against the protrusion, so as to break the ampule and allow a medicament to flow from the ampule to the second compartment.

  • Publication number: 20220144872
    Abstract: The present invention discloses pharmaceutical-grade ferric organic compounds, including ferric citrate, which are soluble over a wider range of pH, and which have a large active surface area. A manufacturing and quality control process for making a pharmaceutical-grade ferric citrate that consistently complies with the established Manufacture Release Specification is also disclosed. The pharmaceutical-grade ferric organic compounds are suitable for treating disorders characterized by elevated serum phosphate levels.

  • Patent number: 10908892
    Abstract: Provided are a computer program product, system, and method for generating and deploying code files compiled on build machines. Source code is maintained at a deployment system. Commands are sent to build machines to compile the source code into object code. The build machines have different operating systems to compile the object code. The deployment system stores the object code for each build machine in an object code file directory to provide executable object code for an operating system installed at the build machine. Different object code file directories are maintained for the object code compiled by the build machines having different operating systems. Access is provided to the object code in the object code file directories to run-time machines. Each run-time machine accesses the object code file directory in the deployment system having the object code compiled for an operating system version deployed on the run-time machine.
