Title: Method and apparatus for monitoring and controlling gain compression in a transmitted signal
Inventor: DOWNEY MICHAEL L
IPC: H04B7/185
Filed: 2002-04-01
Abstract: A method and apparatus for monitoring and controlling the operating point of a satellite transponder amplifier (108). A time domain signal received at a ground station (100) is digitally sampled. A histogram of the received signal is computed and plotted as a graph. Under low compression levels, the histogram generally appears as an approximately bell-shaped curve. Under higher compression levels, the bell-shaped curve becomes distorted. By correlating the acquired histogram to a template histogram, an amount of compression can be determined. This amount of compression indicates the operating point of the transponder amplifiers (108). If desired, the transmission power levels used by the satellite can be adjusted to ensure that the amplifiers operate at desired levels of compression. The invention has an advantage over prior techniques in that the operating point of the transponder amplifiers can be more accurately determined. The operating point can be more precisely adjusted.

Filed: 2004-05-27
Abstract: The present invention relates to an improved trial lenses and also to the use of such improved trial lenses in instruments used to assess or derive the refraction or refractive status of an individual. It is a disadvantage of known trial lens sets that the lenses in such sets are unifocal, that is single vision lenses.  However, this does not allow a practitioner to demonstrate the benefits of bifocals, multifocals or progressives to those who require such lenses when distance refraction lenses are in place over the eyes of a patient. According to the present invention, a lens for use in an instrument used to assess or derive the refraction or refractive status of an individual comprises a distance portion and a near portion.

Title: Methods and apparatus for uniquely identifying a large number of film prints
Inventor: ODGERS CHRIS R
IPC: G06F21/10
Filed: 2003-03-31
Abstract: A method and apparatus for generating many uniquely identifiable media copies from a few uniquely marked masters to reduce the expense of subjecting each media copy to a marking process while maintaining the ability to trace unauthorized copies back to an authorized source. A number of masters of a film or media presentation are digitally or optically marked with identifiers to distinguish each master from each other master. The identifiers provide the ability to distinguish corresponding partitions of segments among masters. The masters with their identifiers are then duplicated. Final media prints are then assembled by combining segments with the duplicated identifiers from various masters in a manner to form segments with unique identifier sequences.  Thus, each final print may be distinguished from each other final print by their identifier sequences.
