Patent CA-2260936-A1 (CA)
Title: Graphical user interface for a motion video planning and editing system for a computer
Inventor: FOREMAN KEVIN J
IPC: G06F3/0483
Filed: 1997-07-25
Abstract: A graphical user interface for a computer-assisted motion video editing system directs a user through the process of editing a video program. The graphical user interface may also enable a user to plan a video program. Alternatively, selectable interfaces within a single window interface, each of which provide a group of planning, capturing, editing, and recording functions can provide such an interface for producing a video program. Other simplifications to the user interface can be provided to assist in editing, such as by maintaining a video display window for displaying the edited video program at a fixed position for all available editing operations. Additionally, video information can be captured directly into a timeline representation of a video program, rather than a bin. Using a storyboard tied to the capturing process, a user is directed through the process of collecting and capturing the video clips to be used in the video program.

Patent CA-2267176-A1 (CA)
Inventor: SCHROEDER WEN ZYO
IPC: D21H17/13
Filed: 1997-09-30
Abstract: The invention relates to tissue products having improved softness properties and methods of making them. Specifically, improved softness is achieved by incorporating a silicone betaine either into the furnish and/or topically applied to the tissue web. Optionally, one or more softeners/debonders are also incorporated into the fiber furnish at the wet end of the tissue machine prior to formation, and/or by an optional topical treatment after the tissue web is formed or dried. The result is a tissue product with added bulk and a smooth surface feel, both properties contributing to improved softness characteristics.

Title: A method, apparatus & computer program product for eliminating edge conditions from an area image processing operations on tiled image data
Inventor: BERRY DAVID T
IPC: G06T15/00
Filed: 1999-04-19
Abstract: Apparatus, methods, and computer program products are disclosed for reducing the overhead associated with performing area-image operations on a tiled image.  The invention detects when an area-image operation, that uses a source pixel contribution map, requires pixel values from one or more adjacent tiles. The invention also generates a list of boxes that represent pixel image information. These boxes are split with respect to the image edges and the tile edges within the image. The split boxes are used to direct memory buffer allocation for cobbled portions of the image and to leave the majority of the tile's pixel information to be operated on within memory buffer holding the tile. Thus, the invention provides a mechanism to assemble image data that crosses tile edges without copying major portions of the tile from one memory buffer to another. Additionally, each resulting box represents sufficient pixel values such that existing image processing techniques currently are applied to area-image operations can also be applied to tiled images. Thus, box can be processed by an MMX-like instruction or image hardware accelerator.

Title: Transmitter method and transmission system using adaptive coding based on channel characteristics
Inventor: HASSAN AMER AREF
IPC: H04L27/01
Filed: 1997-12-16
Abstract: A transmitter (100) receives information for transmission to a receiver (200) over a communication channel (101). A cyclical redundancy checking (CRC) code circuit (106) encodes the information with CRC code for error detection purposes. The CRC coded information is provided to a code switch (108). The code switch (108) provides the CRC coded information to either a first code circuit (110) or a second code circuit (112) forward error correction (FEC) coding. The first code circuit (110) may, for example, encode the information using a FEC Code 1, such as convolutional coding, and the second code circuit (112) may encode the information using a FEC Code 2, such as repetition coding. The code switch (108) selects either the first or second code circuit (110 or 112) based on detected characteristics of the channel (101). The channel characteristics may be obtained from a channel estimation circuit (114), may be obtained from an error feedback signal I3 from the receiver (200) or may be obtained from a combination of both. After the code switch (108) selects the first or second code circuit (110 or 112), the information is appropriately coded to produce a coded signal which is transmitted over the channel (101) by a transmission circuit (116).

Title: Non-invasive glucose measuring device and method for measuring blood glucose
Inventor: PETERS RICHARD K
IPC: A61B5/00
Filed: 1997-06-05
Abstract: This invention is a glucose measuring device for determining the concentration of glucose in intravascular blood within a body part of a subject. The device includes at least one light source (12) having a wave-length of 650, 880, 940, or 1300 nm to illuminate the fluid. At least one recep-tor (14) associated with the light source for receiving light and generating a transmis-sion signal representing the light transmit-ted is also provided. A support piece is included for supporting the light source as-sociated with the respective receptor. The support piece is adapted to engage a body part of a subject. A method for determin-ing the glucose concentration is also pro-vided which calibrates a measuring device and sets the operating current for illuminat-ing the light sources during operation of the device. Once a transmission signal is gen-erated by receptors (14) receiving light via the light source and illuminated blood, and the high and low values from each of the signals are selected and stored in the device (20), the values are subtracted to obtain a single transmission value for each of the light sources. These calculated values are then compared to a database of target values, either using a neural network, or di-rectly compared to determine the glucose concentration, which value is then displayed (28) on the device.

Title: Air filter elements with foam pre-cleaners
Inventor: LANIER ROLAND V JR
IPC: F02M35/024
Filed: 1999-11-29
Abstract: Air filter elements with primary filter medias have foam pre-cleaners with an increased surface area provided by an upstream face which has peaks and valleys. In one embodiment, the peaks and valleys are defined by parallel ribs. If the filter element is a panel-type filter element having a pleated primary filter media, then, in accordance with one embodiment, the pre-cleaner is secured to the primary filter media by adhesive deposits on the peaks of the primary filter media. If the filter element is annular, the pre-cleaner is also annular and is slid axially over a perforated sleeve or screen on the primary filter media and held thereon by friction. By having the upstream surface of the foam pre-cleaner configured in peaks and valleys, the surface area of the upstream surface is increased substantially, which improves the capacity, efficiency and life of the filter element.
