Patent CA-2292516-C (CA)
Inventor: LARSEN MARK SIEVERT
IPC: H04W40/12
Filed: 1998-06-05
Granted: 2006-09-12
Abstract: The invention provides a method of operating a communication network. The network comprises numerous stations, each of which can transmit and receive data in order to transmit messages from originating stations to destination stations opportunistically via intermediate stations. Each station selects one of a number of possible calling channels to transmit probe signals to other stations. The probe signals contain data identifying the station in question and include details of its connectivity to other stations. Other stations receiving the probe signals respond directly or indirectly, thereby indicating both to the probing station and other stations their availability as destination or intermediate stations. The probing station evaluates the direct or indirect responses to identify other stations with which it can communicate optimally. For example, the stations may monitor the cumulative power required to reach another station, thereby defining a power gradient to the other stations, with stations selecting a route through the network which optimises the power gradient. Thus, data throughput through the network is maximised with minimum interference and contention between stations.

Title: A backlight for correcting diagonal line distortion
Inventor: LAINE JEFFREY A
IPC: G02B6/10
Filed: 1999-12-28
Granted: 2005-03-29
Abstract: A backlight apparatus has a collimating waveguide with a light input end (54), a top surface (58), a bottom surface (56), opposing sides (60), a far end opposite the light input end (62), and a total internal reflection critical angle for the material of the waveguide. A plurality of first facets (80) are formed in the bottom surface (56) distributed along the waveguide between the light input end (54) and the far end (62). Each of the first facets (80) has a first facet bottom surface (82) which converges toward the top surface in a direction away from the far end (62) relative to the top surface (58). A light scattering and reflective surface (344) is disposed adjacent the far end of the collimating waveguide. The first facet bottom surfaces (82) cause light rays entering the light input end to be totally internally reflected to the far end of the collimating waveguide wherein the scattering and reflective surface at the far end reflects and scatters light rays incident thereon back toward the light input end. The first facet bottom surfaces (82) then cause the light rays reflected from the far end (62) to exit the top surface (58). The first facet bottom surfaces (82) may be formed either as straight facets or as curved surface facets and may also be alternatively formed having a reflective material layer thereon.
