Patent CA-2376004-A1 (CA)
Inventor: YARED MARLENE
IPC: H04W36/12
Filed: 2000-06-16
Abstract: A method of improving cell change procedures within a General Packet Radio Service (GPRS) network to reduce the handover interruption time while keeping the delays to affordable values for real-time payload services. The data stream interruption is reduced at the air interface level and the core network level. Improvements at the air interface are achieved by reducing the system information retrieval time and pre-allocating the radio resources prior to the MS accessing the new cell. Improvements within the core network are achieved by shortening the inter-SGSN Routing Area Update interruption interval and implementing low latency delay-sensitive requirements and shaping packet traffic for premium traffic.

Abstract: A pedestal head that is sufficiently resilient to allow for alignment of the floor panels during installation of the floor panels and to allow individual access floor panels to maintain their originally-aligned position after having been subjected to a heavy load during use. The pedestal head includes a base and arms extending from and supported by the base for cantilevered movement relative thereto. The base has a first surface, disposed in a first plane, configured to support a first portion of a floor panel. The arm has a second surface configured to support a second portion of the floor panel. The second surface is disposed in a second plane generally parallel to the first plane in a first configuration of the pedestal head. The arm is deflectable by the weight of a panel mounted thereon to define a second configuration in which the second surface is nonparallel to the first plane. The base may include additional arms for supporting additional floor panels. Each arm extends from and is supported by the base for cantilevered movement relative thereto. Each arm also has a surface disposed in the second plane for supporting another floor panel. Typically, four arms are provided to support the corners of four panels mounted on the arms in a substantially level, aligned position regardless of the differences in dimensions caused by variations in manufacturing tolerances.

Title: Color reproduction process
Inventor: LEE DAVID L
IPC: H04N1/60
Filed: 2002-12-23
Abstract: A method of color printing is described in which only two transparent inks are used to reproduce a source image. The original digitally encoded image in red, green and blue colors may be initially adjusted for contrast, brightness, color balance, and tonal value. This is then converted to cyan, magenta and yellow encoding. The two of these channels which best represent the dominant colors of original image are then selected. The critical colors of the original image to be reproduced with reasonable accuracy are determined and spot colors that best represent these are selected from an ink palette. The spot colors are assigned to the selected channels to which they have the closest color relationship. These two channels are next superimposed to form a composite image and their greyscale values are adjusted to produce an image most closely resembling the desired final image. New positive separations are then made and inverted to negative images from which printing plates can be prepared. A third channel may be introduced approximating the color of a colored substrate before the final greyscale adjustment. This channel is not printed, however. An additional procedure useful with colored substrates is to prepare a masking channel which will deposit an opaque ink, usually white, to underlie the two transparent inks and further help control substrate color.  Under this implementation, the third channel is printed. The method is capable of rendering very attractive color images on substrates such as the unbleached kraft paper used for corrugated shipping containers.
