Title: Improvements in or relating to the copy protection of optical discs
Inventor: BASILE CARMEN LAURA
IPC: G11B20/12
Filed: 2005-02-08
Abstract: Generally the more effective is the copy protection provided on an optical disc, such as a DVD, the greater is the likelihood that the copy protection will adversely interfere with legitimate uses of the optical disc.  It is therefore proposed to include at least one region of subversive data within the content in the data area of an optical disc, and then to prevent access to each such region of subversive data during normal playback of the disc. For a DVD, the subversive data may be incorporated within video objects and/or may be in gaps between files in the DVD_Video zone. It is arranged that there are no navigable paths to the regions of subversive data.

Title: Electric generator for vehicle producing dual output voltages
Inventor: KUSASE SHIN
IPC: H02K16/04
Filed: 2005-09-16
Abstract: An electric generator according to the invention includes a rotor, a stator, a rectifier, and a regulator. The rotor includes a field winding. The stator includes a first and a second three-phase winding, each of which has three output terminals corresponding to respective phases. The rectifier has a specially designed three-layer structure, to which the output terminals of the first and second three-phase windings are separately connected, and works to output two different DC voltages through rectifying outputs of the two three-phase windings. The regulator works to regulate the output voltages through controlling a field current supply to the field winding. With such a structure, the electric generator can reliably produce two different output voltages at the same time. Moreover, compared to existing electric generators producing dual output voltages, the structure of the electric generator is much simplified, thus reducing manufacturing cost and the internal impedance of the electric generator.
