Title: Multi-functional transcoder for compressed bit streams
Inventor: LUTHRA AJAY
IPC: H04N7/26
Filed: 1999-12-31
Abstract: A method and apparatus for transcoding digital video data, for example, at the headend of a cable or satellite television network. A generic multi-functional transcoder architecture has a "post-pre-processing engine" that provides a number of processing functions for implementing desired format conversions according to a user selection signal or an automatically generated selection signal. The processing functions can change frame size, frame rate, color space sampling format, interlaced or progressive scan format, resolution, and provide noise/deblocking filtering, for example. The system also allows the control of several transcoders to convert several bit streams with different formats into corresponding bit streams with a common format.      Furthermore, the transcoder avoids the need for motion estimation.

Patent CA-2305975-A1 (CA)
Inventor: GREENWOOD KEN C
IPC: H04L12/28
Filed: 2000-04-19
Abstract: A simple and low cost architecture for coupling wireless local area network signals between geographically distributed access points and centrally located internetworking devices. A cable access point (CAP) is associated with each respective microcell.      Each CAP includes a remote bridge to convert such signals to a convenient transport format depending upon the available cabling. For example, if the available cabling is a cable television (CATV) plant, the transport signals are first converted to a T1 format and up-converted to a carrier frequency suitable for the CATV plant. Alternatively, the transport signals may be converted to IEEE 802.3 cable modem signals. If the available cabling is twisted pair telephone type wiring, the remote bridge converts the transport signals to a suitable Digital Subscriber Line (xDSL) format. The transport signals are collected at a central distribution or head end access point (HAP). At this location, a remote bridge then converts the signals from the up-converted T1 format or the xDSL format, back to the Ethernet local area network format. These Ethernet signals are then suitable for coupling to a local area network hub or other internetworking equipment such as repeaters, bridges, routers, and gateways.
Patent CA-2313003-A1 (CA)
Title: Absorbent articles having liquid shrinkable breathable backsheets
Inventor: CIAMMAICHELLA FABIO
IPC: A61F13/15
Filed: 1997-12-15
Abstract: The present invention relates to absorbent articles such as sanitary napkins and panty liners which are breathable by the incorporation of a breathable backsheet and have a reduced tendency to exhibit garment wet through. The backsheet comprises at least one vapour permeable apertured layer comprising a non soluble, liquid shrinkable material such as polyvinyl alcohol. Upon contact with the fluid discharge the material shrinks thereby causing the apertures of the layer to close and hence prevent the passage of liquid through the backsheet onto the garment of the wearer.

Abstract: An apparatus for preparing a boned pork product includes a searing oven at a high temperature cooking station for braising and charring the boned pork product using radiant heat. The apparatus also includes a dual box, spiral steam cooker at a low temperature cooking station for cooking the boned pork product using steam to yield a fully-cooked, boned pork product. The apparatus further includes a freezer at a freezer station for freezing the fully-cooked, boned pork product. A first conveyor belt is disposed between the searing oven and the steam cooker and serves to mechanically transport the boned pork product from the high temperature cooking station to the low temperature cooking station. A second conveyor belt is disposed between the steam cooker and the freezer and serves to mechanically transport the fully-cooked, boned pork product from said low temperature cooking station to said freezer station. Together, first and second conveyor belts continuously and mechanically feed the product through the apparatus. In use, the first conveyor belt advances the boned pork product through the searing oven which braises and chars the product using radiant heat. The first conveyor belt further advances the product into the dual box, spiral steam cooker which fully cooks the product. The steam cooker advances the fully-cooked product onto the second conveyor belt which, in turn, advances the product into the freezer. The freezer chills the product for distribution purposes.
