A television broadcasting system and methods that manages the insertion of targeted advertisements and other messages into live satellite or Internet broadcasts or other types of broadcasts into out-of-home locations such as health clubs. The insertion of targeted advertisement and other messages are accomplished by a satellite service provider purchasing live network broadcasting feeds with a license to strip out existing commercial advertisements and replace them with targeted advertisements to match the demographics of the viewing audience at health clubs and other non-home locations nationally, regionally and locally where the viewer is unable to change or delete the targeted advertisements while viewing the live broadcast programming from the networks.

The invention discloses an optical network unit ONU and a method for reporting capacity thereof. The method comprises steps as follows: an ONU registers to an optical line terminal (OLT); after finishing the registration, the ONU reports the locally stored capacity information to the OLT; and when detecting that the actual capacity information is different from the stored capacity information, the ONU reports the actual capacity information to the OLT. By using the invention, the ONU can completely reflect the self capacity to the OLT in time, thereby implementing quick registration of the ONU as wells as accurate and complete reporting of capacity.

In a six-degree-of-freedom precision positioning system, magnetic force and fluid buoyancy are used to levitate a platform, and the non-contact magnetic force between electromagnets and magnets forms a main driving force for the platform. Therefore, no friction is present in the system and no lubricating mechanism is needed for the system. Moreover, in the system, electric current is converted by electromagnets and magnets into a magnetic driving force without using any transmission gears. Therefore, the backlash phenomenon that is not easily controllable in the conventional servo positioning systems is avoided. The system has simplified structure without the need of complicated fabrication, and utilizes the properties of fluid to achieve low power consumption, high precision positioning, and fast response.

[Problem to be Solved]To provide a balancer that can correct dynamic imbalance in rotatable bodies such as machine tools. The correction for low-speed rotation is possible to the same extent as that for high-speed rotation.[Solution to Problem]The balancer, attachable via its attaching portion to a rotatable body, and rotatable together therewith about its rotation axis, includes: weights of same mass and shape; and a weight holder with storage chambers for housing the weights, respectively, such that the weights can oscillate in arbitrary directions. The weight is shaped similar to and smaller than the chamber. The chamber is a cylindrical space extending alongside its central axis; and has concave curved ends perpendicular to the central axis. Midpoints of the central axes of the chambers are contact points on a circumference of a circle having the rotation axis as its center and being on an arbitrary plane perpendicular to the rotation axis; and are positioned so that they create a rotational symmetry around the rotation axis.
