Abstract: In accordance with an embodiment, a system for device localization and tracking for magnetic resonance (MR) image-guided interventional procedures includes an input configured to receive a set of MR images of a region of interest of a subject acquired using a magnetic resonance imaging (MRI) system and a physical device localization system. The region of interest includes a device. The physical device localization system includes a first neural network coupled to the input and configured to localize a feature of the device on the set of MR images and a second neural network coupled to the first neural network and configured to generate an estimate of a physical position of the device based on the localized device feature. The system further includes a display coupled to the second neural network and configured to display the estimate of the physical position of the device.

Abstract: A system for imparting motion of an object includes: (1) at least one first hydrostatic actuator; (2) a hydraulic transmission conduit; and (3) at least one second hydrostatic actuator. The first hydrostatic actuator is connected to the second hydrostatic actuator via the hydraulic transmission conduit, such that an input displacement applied to the first hydrostatic actuator is transmitted via the hydraulic transmission conduit to the second hydrostatic actuator to impart motion of the object.

Abstract: A cell phone case that includes an integrated key holder is provided. The cell phone case can include a first portion that covers the sides and back of an upper portion of a cell phone body and a second portion for covering the sides and back of a lower portion of the cell phone body. The first portion and the second portion can be capable of being engaged with each other to form the cell phone case. The first portion and/or the second portion can include on a back panel, a side facing away from a screen of the cell phone, a cutout sized to removably hold a key.
