  • Collision prevention for autonomous vehicles
    Patent number: 11130630
    Abstract: Disclosed autonomous mobile robot systems can be used to safely and efficiently navigate through a facility while avoiding objects in the path of the autonomous mobile robot during completion of a task. Specifically, a safety zone of a first size may be generated around an autonomous mobile robot based at least in part on first data from a first set of sensors associated with the autonomous mobile robot that are configured to identify an object within the safety zone. Information indicating a current speed of the autonomous mobile robot from associated propulsion components may be received and utilized to update the first size and a shape of the safety zone. Instructions to cease propulsion of the autonomous mobile robot may be transmitted to the propulsion components based on first data identifying the object within the updated first size of the safety zone.

  • DYNAMIC NAVIGATION OF AUTONOMOUS VEHICLE WITH SAFETY INFRASTRUCTURE
    Publication number: 20210260764
    Abstract: Disclosed autonomous mobile robot systems can be used to safely and efficiently navigate through a facility while avoiding objects in the path of the autonomous mobile robot during completion of a task. Specifically, a first bounded area based on first sensor data may be generated around an autonomous mobile robot where the first sensor data is used to identify objects in a travel path for the autonomous mobile robot and determine a speed for navigating the facility. A second bounded area of a size less than the first bounded area may be generated around the autonomous mobile robot based on speed information from propulsion components of the autonomous mobile robot. A new travel path and new speed information may be generated based on identifying an object in the travel path, dimensional measurements of a space around the object, and a current size of the second bounded area.

  • Pathway analysis for identification of diagnostic tests
    Patent number: 11011273
    Abstract: The present inventive subject matter provides apparatus, systems, and methods in which a diagnostic test is identified, where the diagnostic test is for determining whether a particular treatment is effective for a particular patient based on one or more characteristics of a patient's cells. When a treatment is developed with the potential to treat one or more diseases, the drug can have different effects on different cell lines related to the diseases. A machine learning system is programmed to infer a measurable cell characteristic, out of many different measurable cell characteristics, that has a desirable correlation with the sensitivity data of different cell lines to a treatment. The machine learning system is programmed to then determine, based on the correlation, a threshold level of the cell characteristic the patient should exhibit in order to recommend administering the treatment.

  • PROGNOSTIC INDICATORS OF POOR OUTCOMES IN PREGNANT METASTATIC BREAST CANCER COHORT
    Publication number: 20210142864
    Abstract: Transcriptomics data from tumor tissue of patients diagnosed with metastatic breast cancer are clustered and associated with overall survival of the patients. A subset of genes from one of the cluster associated with poor outcome are used to generate a survival prediction model predicting a survival time based on expression levels of a plurality of genes. Using such generated survival prediction model, a survival time of a patient diagnosed with metastatic breast cancer can be predicted and a treatment regimen can be updated or generated based on the survival time.
