Abstract: An embodiment of the invention provides a system for automatically deriving a parameter of a human heart from ultrasound results. A first neural network is arranged to receive a plurality of echocardiographic images and to classify the images into one of at least a two-chamber view and a four-chamber view. A second neural network is arranged to receive echocardiographic images comprising a two- or four-chamber view and to identify the endocardial border of the left ventricle (LV) for each view. End-systole and end-diastole images are then identified and a parameter such as LV volume, ejection fraction, global longitudinal strain and regional longitudinal strain is calculated.

Abstract: The invention provides an equipment and a system that addresses the key concerns of eating/drinking in public while minimizing the chance of contamination of the eater and the public in general. The equipment can be a face mask, a face shield or a helmet that completely encloses at least the mouth and the nose of a person while providing intermittent access to the mouth without removal of the equipment. A mouth opening is provided on the equipment which is selectively blocked or unblocked by a covering element moved by a moving mechanism that moves the cover element to block or unblock the mouth opening. The mouth opening is selectively blocked or unblocked based on the distance between an activating element provided on a utensil or a wearable device and a receiving element provided on the equipment.
