Some embodiments provide a system for external manipulation of magnetic nanoparticles in vasculature using a remotely placed magnetic field-generating stator. In one aspect, the systems and methods relate to the control of magnetic nanoparticles in a fluid medium using permanent magnet-based or electromagnetic field-generating stator sources. Such a system can be useful for increasing the diffusion of therapeutic agents in a fluid medium, such as a human circulatory system, which can result in substantial clearance of fluid obstructions, such as vascular occlusions, in a circulatory system resulting in increased blood flow.

A device for online gaming includes an actuation component and a controller communicatively coupled to a computer system. The controller is configured to perform operations including detecting an actuation of the actuation component, wherein the actuation component is associated with performing of an action in a video game executed by the computer system. Responsive to detecting the actuation, an instruction is provided to the computer system to perform the action, wherein, based on a current value of a timer, the computer system restricts the action from being performed. The timer, having been previously initiated based on a prior actuation of the actuation component, relates to a cooldown period during which the action cannot be repeated after the action is performed. Responsive to receiving a command from the computer system, a tactile effect is generated as an indication to a user that the action can be repeated.

A system that incorporates the subject disclosure may include, for example, a button including a fixed force magnet coupled to a first housing assembly component serving as a top portion of the button, a variable force magnet coupled to a second housing assembly serving as a bottom portion of the button, and a spring coupled to the fixed force magnetic and the variable force magnet for repelling the fixed force magnet from the variable force magnet according to a spring constant of the spring. The variable force magnet emitting a magnetic field to counter the spring constant and thereby adjust a force required to depress the button. Additional embodiments are disclosed.

A magnetization device and the like appropriate for various magnetization requirements are more easily provided. Provided is a magnet holding device that is capable of holding a magnet. The magnet holding device includes a ring-shaped portion that is openable/closable and an open/close mechanism allowed to keep the ring-shaped portion in a closed state. The magnet is arrangeable in the ring-shaped portion, and the number of the magnets to be arranged is variable.

A magnetic field control system according to an embodiment of the present invention may comprise: a structure forming part for forming a three-dimensional structure having an inner space; a magnetic field generating part for generating a magnetic field, the magnetic field generating part being formed to extend from a predetermined position of the structure forming part and being disposed to face a target region defined in the inner space; and a power source part for supplying electric power to the magnetic field generating part.

An organizer for a plurality of metallic objects has a nonmetallic housing and a magnetic core. The nonmetallic housing has opposing top and bottom external surfaces. A ridge projects from a periphery of the top external surface. The magnetic core attracts metal towards the geometric center of the top external surface and towards the ridge at the periphery of the top external surface. In some implementations, portions of the magnetic field attract metal in the directions: (i) perpendicular to the geometric center of the top external surface; (ii) outward from the geometric center of the top external surface; and (iii) toward the ridge on the top external surface. Implementations have the magnetic core with a square cross section and north and south poles separated by a distance substantially less than the width of the substantially square cross section, and with its magnetic field in the shape of a torus.

A system that incorporates the subject disclosure may include, for example, a method that includes identifying a plurality of devices associated with a computing device, identifying status information from each device of the plurality of devices, and identifying presentation features for each device of the plurality of devices. The method further includes receiving presentation information indicating a setting to present first status information from a first device of the plurality of devices via a selected device of the plurality of devices, wherein the first status is presented on the selected device by a selected presentation feature of the selected device.
