Control system, apparatus compatible with the system, and remote controller

PROBLEM TO BE SOLVED: To accomplish a control system in which relative positions of a remote controller and a television are recognized and contents can be selected or sound effects can be adjusted at the side of the television so as to be suited to the recognition by effectively utilizing an imaging means provided in the remote controller. SOLUTION: An external form of a liquid crystal television 100 is imaged by an imaging means 210 provided in a remote controller 200 and when a picked-up image is put on a control signal Sc and supplied from a control signal projection unit 220 to the liquid crystal television 100, at the side of the liquid crystal television 100, the relative position of the remote controller 200 (namely, of a viewer) to the liquid crystal television 100 is calculated from an extent of trapezoidal distortion of the picked-up image. The sound volume of left and right speakers 103, 104 is then balanced to be suited to the calculated relative position, and directivity of sounding is turned toward the viewer.

Single energizer face seal for rocks bits with floating journal bearings

The present invention is a self adjusting, volume balanced, single energizer rigid face seal for rolling cutter drill bits with floating journal bearings. Volume balancing is accomplished by utilizing a floating static seal between the rigid face seal ring and the bearing shaft. This floating static seal ring is moved axially within a annular groove by the volume pulses caused by the axial play of the cutter when in operation. At one end of the annular groove the geometry of the rigid seal ring and bearing shaft are set such that the seal assembly achieves volume balance when the bearing is running on its OD. If the bearing is running on its OD, the floating static seal will move from where ever it is in the annular groove by the volume pulses until it reaches the balance volume position.
