Patent CA-2314713-A1 (CA)
Inventor: TREMBLAY FRANCOIS
IPC: H04L1/00
Filed: 2000-07-28
Abstract: This invention relates to an extended politeness power cutback for both G.lite.bis and G.dmt.bis D/S and U/S signals, together with a G.hs.bis-defined maximum U/S and D/S  transmit PSD levels. This latter is applied regardless the loop length and it is assumed to be based on MIB indications and on ATU-R and ATU-C characteristics. The rationale behind it is to both impose a general power consumption limitation and to limit interference into adjacent pairs (this being particularly important in DLC deployments). A G.hs.bis transaction (to be defined in future contributions) would exchange and negotiate the requirements coming from the operator (MIB-based) and from the ATUs. The extended politeness cutback can be applied on top of the max PSD  limitation on short loops. For the ATU-C is ensures a statistical power savings over the served subscriber area without a significant data rate degradation. For U/S, it reduces the self FEXT  into adjacent pairs, thus improving the throughput for the modems served by the same feeder cable.  This feature could be disabled by the operator when in presence of a NEXT-limited environment. The contribution specifically refers to G.dmt.bis; some changes are required for G.lite.bis when in presence of a Fast Retrain Power cutback.

Patent CA-2316496-A1 (CA)
Inventor: MCGARRY STEVEN P
IPC: G02F1/313
Filed: 2000-08-17
Abstract: An adaptive optical waveguide router in which routing paths may be dynamically created by the use of a scanning system. The optical router interconnects at least one optical input to a at least optical output. The optical waveguide layer employed is substantially comprised of a photosensitive material which has a change in index of refraction at one optical wavelength when exposed to a different optical wavelength and which, in some way, may be restored to it's original state. One such material is Bacteriorhodopsin which shows a photocycle in the visible region of the optical spectrum. The scanning system, in response to routing information, traces a routing path(s) between an input(s) and a selected output(s) which alters the index of refraction in the path(s) traced in the photorefractive material. An optical input signal then propagates along the traced path between the selected input(s) and the selected output(s).

Title: A lenticular illumination system
Inventor: BEESON KARL W
IPC: F21V5/02
Filed: 1999-03-03
Abstract: An optical illumination system (2) comprising a waveguide (16) that accepts light and transmits the light via total internal reflection. Attached on one face of the waveguide (16) is an array of lenticular microprisms (28), with each microprism (28) having a light input surface (30) optically coupled to the waveguide (16) and a light output surface (32). The light input surface (30) is defined by a number of tapered grooves (34) which prevent light from escaping form the waveguide (16) and further redirect light within the microprism (28). Light that escapes from the waveguide (16), reflects off the tilted sidewalls (36, 38) of the tapered grooves (34) and emerges from the microprism (28) as a spatially directed light source. An array of lenticular microlenses (60) may be positioned to accept the output of the microprisms (28) so that the light exiting from the microlenses (60) is a substantially collimated light source.
