Abstract: Systems and techniques for grasp selection may include receiving one or more candidate object trajectories and a current grasp of a robotic hand on an object, sampling random candidate grasps for the one or more candidate object trajectories based on the current grasp, generating one or more grasps to be optimized for each of the one or more candidate object trajectories based on the sampled candidate grasps, and optimizing one or more of the grasps to be optimized for each of the one or more candidate object trajectories based on a cost function.

Abstract: A welding screen includes a primary barrier made of a magnetic sheet. The welding screen enhances safety by halting or restricting the motion of magnetic and paramagnetic by-products, thereby preventing flame, light, magnetic material, sparks and dust from being scattered during welding or post-weld grinding. This improvement can be applied to various type of welding screens (welding curtain, welding windshield), by using a flexible magnetic sheet material as the primary barrier material.

Abstract: A welding spatter protection screen formed primarily of magnetic sheeting or being a magnet is provided to further safety by halting or restricting the motion of magnetic and paramagnetic by-products, thereby preventing flame, light, magnetic material, sparks and dust from being scattered during welding or post-weld grinding.

Abstract: There is disclosed an umbilical assembly comprising at least one elongated umbilical element, and at least one light weight, high strength reinforcing rod.

Abstract: A cardiac imaging system comprising two or more camera heads is disclosed. Each camera is capable of generating first pass and/or gated blood pool images. One of the camera heads may be oriented at an anterior position with respect to the patient, and the other camera head may be oriented at a side position.

Abstract: A system for cardiac imaging is disclosed. A single camera system may be used to perform both gated blood pool and first pass imaging. The first pass camera tags the ECG/gated portion of the patient's exam to the first pass bolus as it travels through the right ventricle (RV), lung field and left ventricle (LV). In a typical test, a standard first pass test procedure is used except the patient is also connected to an ECG output device. The patient's R-wave is tracked and tagged to the first pass test data. The results may be displayed, for example, in a cine fashion, a static systolic/diastolic frame, a phase/amplitude frame, or any other desired format.
