A method for controlling presentation of data through a wireless home entertainment hub in a home entertainment system includes obtaining a registration for a plurality of source devices and for one or more sink devices. An object thereof is to provide a gear which has durability and is excellent in the balance between dimensional accuracy and rotation transmission accuracy. Flow-diverting elements are provided, e. The invention is also directed to a bone compression system wherein the plate includes a string attached to each end of the plate and a tensioner for facilitating the movement of the plate from the pre-formed shape to the at least one elastic shape. The measurement device is operable to measure the carrier envelope phase of the generated laser pulse and the feedback controller is operable to control the positioning element based on the measured carrier envelope phase to vary the separation distance of the pulse modification elements and control the carrier envelope phase of laser pulses generated by the laser source.
