  • Patent number: 12639973
    Abstract: A computer-implemented method for digitizing clinical documents comprises receiving a clinical document and a policy type. The method further comprises de-skewing and removing noise from the page. The method further comprises generating extracted text from the processed page using OCR, analyzing the extracted text to generate a classification label for the page using a multinomial classifier model comprising an LSTM neural network, which has been trained to recognize different classes of page based on similarities to a corpus of historical pages that have been previously classified. The method further comprises recognizing a specified keyword within the extracted text, using an NER that is trained using policy data relating to a policy having the policy type, and displaying a visual representation of the clinical document with a visual indicator of the presence of the specified keyword on the page, and a visual indicator of the classification label.

  • Publication number: 20250364138
    Abstract: A method for authorizing a treatment may include receiving a treatment authorization request, creating an extracted text of a historical record using optical character recognition on the historical record, determining whether to analyze authorization performance of the treatment using a machine learning authorization process, in response to a determination to analyze authorization performance of the treatment using a machine learning authorization process: identifying authorization criteria for the treatment based on treatment authorization guidelines; identifying a natural language record processing model corresponding to expense authorization guidelines, and performing natural language processing on the extracted text of the record in accordance with the identified natural language record processing model to identify relevant record data in the record, determining whether the relevant record data meets the authorization criteria and in response to a determination that the relevant record data meets the auth

  • Patent number: 12293835
    Abstract: An improved machine learning based method for authorizing the performance of a treatment, comprising the steps of: receiving a treatment authorization request, the treatment authorization request including a historical record of the person who will receive the treatment and treatment identifying information relating to the treatment; creating an extracted text of the historical record using optical character recognition on the historical record; determining whether to analyze authorization performance of the treatment using a machine learning authorization process, wherein the determination is based on treatment identifying information and whether treatment authorization guidelines exist for the identified treatment; in response to a determination to analyze authorization performance of the treatment using a machine learning authorization process: identifying authorization criteria for the treatment based on the treatment authorization guidelines, wherein the authorization criteria includes records data condi

  • Patent number: 11996210
    Abstract: Typically modulation systems are incapable of performing synchronous modulation for high-energy radiation systems. A method and system for performing high-energy synchronous radiation modulating is described. The method includes providing an oscillatory diffractive element, with the oscillatory diffractive element capable of being oscillated over a range of angles. A radiation source provides radiation to the oscillatory diffractive element. An electrical signal is provided to electrodes that oscillate the oscillatory diffractive element to modulate the radiation. A temperature controller controls the temperature of the oscillatory diffractive element to tune the oscillatory motion of the oscillatory diffractive element.

  • Patent number: 11866322
    Abstract: A microelectromechanical device for diffracting optical beams comprises a diffractive element suspended over a channel. The diffractive element is configured to receive an optical beam and diffract and/or transmit the optical beam based on an orientation of the diffractive element. At least one torsional actuator is operatively connected to the diffractive element. The at least one torsional actuator is configured to selectively adjust the orientation of the diffractive element. The diffractive element has a diffractive element resonant frequency that is nearly the same as a resonant frequency of the optical beam.
