Patent CA-2384674-A1 (CA)
Inventor: MCRAE PAUL E
IPC: G06F17/30
Filed: 2000-09-07
Abstract: Various embodiments of the invention provide increased speed and decreased computer processing for playing and navigating multimedia content by using t wo types of data objects for displaying the multimedia content. The first data object type includes rendered multimedia content data for a rendered cache, or rendering instructions for a paint stream cache or a layout cache. The paint  stream cache and layout cache can take advantage of increased client processing capabilities. The second data object type provides semantic conte nt corresponding to the rendered multimedia content. The storage medium in whic h these two types of data objects are contained is referred to as a rendered cache. The semantic content can include locations, sizes, shapes, and target  universal resource identifiers of hyperlinks, multimedia element timing, and  other content play instructions. The very fast play of content stored in the  rendered cache is due to the elimination of the steps of laying out the content, rendering the content, and generating the semantic representation o f the content. These steps are required each time the content is played after retrieval from a conventional cache. The only steps required for playing content from the rendered cache are to read the rendered content, read the semantic content,restore the semantic representation, and play the content. The caching mechanism provided by various embodiments of the invention is independent of content file format and the stored semantic content file form at.

Title: Optical recording medium with different wobble characteristics between the user data area and the lead-out area
Inventor: SHIM JAE-SEONG
IPC: G11B7/007
Filed: 2002-06-17
Abstract: An optical recording medium has a user data area and a lead-out area, wherein the user data area and the lead-out area each has grooves and lands formed thereon. Wobbles are formed on at least one lateral surface of grooves of the user data area and the lead-out area, and configured such that wobble characteristics are made different between the user data area and the lead-out area. Different types of wobbles are formed on the grooves of either the user data area or the lead-out area, thereby preventing an optical pickup that performs recording/reproduction from deviating from the user data area. Also, in a multi-layer optical recording medium, a whole area of a recording layer is configured to have a same condition, thereby preventing deterioration in reproduction and/or recording due to a difference in light power transmittance of another recording layer.

Filed: 2000-12-11
Abstract: A reamer shoe (1) for mounting on a tubing string has a reaming area (5) supporting a plurality of discrete reaming members (6) typically formed as simple geometrical shapes. The reaming members provide complete circumferential coverage of the shoe body (2) but the individual reaming members are non-continuous and do not fully extend either longitudinally along or circumferentially around the reaming area on the shoe body. The invention therefore provides a reamer shoe for reaming a bore in preparation for receiving casing, which is effective on rotation or reciprocation, regardless of direction or speed.

Title: Reduced keyboard disambiguating system
Inventor: KING MARTIN T
IPC: G06F3/023
Filed: 1998-09-24
Abstract: A reduced keyboard disambiguating system. The keyboard has twelve to sixteen keys, nine of them labeled with numerous letters and other symbols, and those nine plus one more are associated each with one of the ten digits. Textual entry keystrokes are ambiguous. The user strikes a delimiting "Select" key, or a key with an unambiguous character interpretation, at the end of each word, delimiting a keystroke sequence that could match any of a plurality of words associated with the same keystroke sequence. Each input keystroke sequence is processed with a complete vocabulary, and words which match the sequence of keystrokes are presented to the user in order of decreasing frequency of use. The vocabulary is stored in a special format that supports significant data compression without requiring additional processing. In addition, stems of longer words whose initial letters match the sequence of keystrokes are also presented to the user in order of decreasing frequency of use. If the frequency of the words associated with a stem is high enough, that stem is displayed as the default word object. Activations of an ambiguous key associated with a plurality of punctuation characters are disambiguated from the context of the surrounding keystrokes.

Title: Image processing system for detecting when an airbag should be deployed
Inventor: FARMER MICHAEL EDWARD
IPC: G06T7/20
Filed: 2003-01-15
Abstract: The invention can determine whether a collision has occurred, whether an airbag should be deployed, and what the desirable strength of an airbag deployment should be based on occupant characteristics obtained from the segmented image of the occupant. Using interacting multiple model Kalman filters, the invention can infer three-dimensional characteristics from a two-dimensional image, and predict the location, velocity, and acceleration of the occupant. Kalman filters are used with respect to all measurements to incorporate past predictions and measurements into the most recent estimates and predictions in order to eliminate the "noise"  associated with any particular measurement. The system can predict the position and shape of the occupant at a faster rate than the rate at which the sensor collects data.  Occupant characteristics can be compared to corresponding predetermined data associated with various occupant modes, including the mode of crashing, to determine if a collision has occurred.
