  • Patent number: 12254990
    Abstract: A method for determining the health of an organ, specifically the thymus, using medical image data is disclosed. The method involves generating a foundation model by retrieving and pre-processing a set of images related to various organs, including CT scans of the thymus. A deep convolutional neural network is then used to produce embedding vectors, which are refined through a self-supervised learning framework. A task-specific classifying model is generated, comprising a Quality Control (QC) model and a score model. The QC model provides binary predictions differentiating between normal thymus degradation and abnormalities, while the score model evaluates fat and soft tissue levels in the thymus. The health of a potential organ is evaluated by receiving a CT of an organ to be evaluated, generating an embedding vector using the foundation model, and applying the task-specific classifying model to produce a health score.

  • Patent number: 6532812
    Abstract: Described is a method of optimizing tire pressures in order to obtain maximum tire tread life and performance. The method involves calculation of the live and dead loads on each individual tire of the vehicle. Grown diameter of the tires in use is obtained from published data sheets. The grown diameter is then multiplied by an empirically derived tread length determining factor to obtain an optimum tread length in contact with the road surface. In turn the tread length is multiplied by effective tread width to obtain a footprint area for the tires. Finally, the load carried by the individual tires is divided by the footprint area to obtain an optimum inflation pressure.

  • Patent number: 3933219
    Abstract: The system provides improved bass response and stereo effect with the use of a plurality of speakers that are preferably disposed in a unitary cabinet. If two woofer speakers are employed they are disposed at an angle to each other and are disposed relatively close to each other to provide mutual coupling and improved bass response. Also, the speakers are spaced from a rear wall of the listening room so as to permit the coupling and also to enhance the spacial response by sound refelection from not only the rear wall but also the side walls thereby also providing improved sound realism through increased reverberation. Quadraphonic operation is also readily provided with the use of two cabinets.
