摘要： A magnetic manipulation system and method for moving and navigating a magnetic device in a body are provided. The system includes a robotic parallel mechanism having at least three electromagnets and at least three electromagnetic coils coupled to the at least three electromagnets, respectively. The electromagnetic coils are actuated to keep the electromagnets in static conditions or move the electromagnets along a desired trajectory, a current control unit supplying currents to the electromagnetic coils which have soft iron cores. The currents supplied by the control unit are configured to generate dynamic magnetic field in the soft iron core's linear region. The current control unit and the robotic parallel mechanism are configured to generate desired dynamic magnetic fields in desired positions within a workspace to control a magnetic device, and a three-dimensional position sensor is configured for performing a close loop control of the robotic parallel mechanism.

摘要： Provided is a particle beam therapeutic device, a particle beam therapeutic system, an irradiation planning device, and a particle beam irradiation method. In a particle beam therapeutic system 1, while a magnetic field generation device 9 generates a magnetic field that affects a particle beam in the vicinity of a target of a subject, a particle beam extracted from an ion source 2 is accelerated by an accelerator 4, transported by a beam transport system 5, and applied from an irradiation device 6. In the irradiation of the particle beam, an irradiation planning device 20 creates an irradiation plan of the particle beam in consideration of the influence of the magnetic field, and applies the particle beam based on this irradiation plan.

摘要： Some aspects include a ski binding system using controllable electromagnets, alone or in combination with permanent magnets, as means of attaching or releasing a ski boot to a ski during use. Some aspects include a ski binding system using a controllable solenoid. In some aspects, microprocessor-based control releases binding electronically based on input from sensors located in binding, ski and/or boot, as well as in other equipment or clothing connected to them or to skier, or binding releases when a mechanical threshold is overcome. In some aspects, sensor data are recorded for analysis of system performance and for adjustment and improvement of system parameters based on data analytics.
