  • Publication number: 20240085914
    Abstract: In various examples, techniques for determining perception zones for object detection are described. For instance, a system may use a dynamic model associated with an ego-machine, a dynamic model associated with an object, and one or more possible interactions between the ego-machine and the object to determine a perception zone. The system may then perform one or more processes using the perception zone. For instance, if the system is validating a perception system of the ego-machine, the system may determine whether a detection error associated with the object is a safety-critical error based on whether the object is located within the perception zone. Additionally, if the system is executing within the ego-machine, the system may determine whether the object is a safety-critical object based on whether the object is located within the perception zone.

  • Publication number: 20200385450
    Abstract: The invention provides therapeutic antibodies and methods for treatment of diseases associated with diseases associated with aggregation of ?-synuclein, e.g., in the brain of a subject. Such methods provide administration of therapeutic antibodies to elicit a beneficial immunogenic response against aggregation of ?-synuclein. The methods are particularly useful for prophylactic and therapeutic treatment of diseases associated with the formation of Lewy bodies, e.g., Parkinson's disease.

  • Publication number: 20130071872
    Abstract: A single-used matrix sampling device for the single-used, disposable or autoclavble packed-bed bioreactor is provided herein. The present invention includes a tube means and a matrix collecting means. The matrix collecting means configured for collecting the cell culture matrix includes a receptacle and a pulling means connected to the receptacle or the matrix collecting means could be scoop-like in configuration; the tube means is configured for preventing the matrix collecting means from being contaminated while mechanically or pneumatically sampling; and the tube means could be sealed to enclose the sampled matrix collecting means after sampling. A single-used matrix sampling method for a single-used, disposable or autoclavble packed-bed bioreactor is also provided. The present invention could be utilized to aseptically collect the cell culture matrix from the packed-bed bioreactor without requiring to face the risks of contamination.
