Abstract: Embodiments of the present disclosure include a method, device and computer readable medium involving receiving image data to detect tissue lesions, passing the image data through at least one first convoluted neural network, segmenting the image data, fusing the segmented image data, and detecting tissue lesions.

Abstract: A system is proposed for automated detection and segmentation of lung cancer from registered pairs of thoracic Computerized Tomography (CT) and Positron Emission Tomography (PET) scans. The system segments the lungs from the CT data and uses this as a volumetric constraint that is applied on the PET data set. Cancer candidates are segmented from the PET data set from within the image regions identified as lungs. Weak signal candidates are rejected. Strong signal candidates are back projected into the CT set and reconstructed to correct for segmentation errors due to the poor resolution of the PET data. Reconstructed candidates are classified as cancer or not using a Convolutional Neural Network (CNN) algorithm. Those retained are 3D segments that are then attributed and reported. Attributes include size, shape, location, density, sparseness and proximity to any other pre-identified anatomical feature.

Abstract: This disclosure is generally directed to systems and methods for wirelessly charging a battery in a mobile robot. In an example method in accordance with the disclosure, a mobile robot locates and approaches a wireless battery charging station (by using an onboard camera, for example). The mobile robot then executes an alignment procedure to align a wireless charge receiving pad of the mobile robot with a battery charging pad of the wireless battery charging station. The alignment procedure may involve the mobile robot moving the wireless charge receiving pad in any of three axial directions, such as, backwards, forwards, sideways, upwards, and/or downwards. After alignment is completed, the mobile robot may establish a wireless handshake with the wireless battery charging station. The wireless handshake can include a verification of an authentication of the mobile robot to access the wireless battery charging station, followed by a wireless battery charging operation.

Abstract: A dispensing box with a roll tensioner houses a material roll and maintains a material cutting edge in an upward position for easy grasping during use. The roll tensioner comprises distal and proximal end sections with opposing bottom tabs separated by a spring back reversion section. A roll tensioner slide assembly integrated in the front wall of the dispensing box has opposing parallel slits terminating at opposing parallel slots with parallel locking flaps. Opposing bottom tabs of a roll tensioner are inserted through the parallel slots, resting in a first position during non-use and adapted to be slid down into a second position in the parallel slits when later engaged for use to retain the material cut edge in the upward position for easy grasping. The locking flaps have break-away top and bottom walls abutting a bend wall and are in a stored position and later opened outward to a locking position during use to prevent movement of the roll tensioner.
