Patent CA-2386173-A1 (CA)
Inventor: ROSS ROBERT J
IPC: G01N29/11
Filed: 2000-09-21
Abstract: A system and method of detecting anomalies and/or grain variations in a wooden member. At least one ultrasonic transmitter (401) applies an ultrasound waveform into a surface of a wooden member (100) so as to generate a multiplicity of ul-trasonic waves including, e.g., longitudinal and shear waves. These ultrasonic waves are measured after propagation through the wooden member by at least one ultrasonic receiver (402) disposed on the same surface of the wooden member. At least one ultrasonic receiver (501) may also be placed opposite the ultrasonic transmitter (401) so as to detect radial transmission of the longitudinal ultrasonic wave at a point across the wooden member. The received ultrasonic waves are processed to determine anomalies and/or grain variations in the wooden member at positions of the wooden member between the ultrasonic transmitter and the ultrasonic re-ceiver(s). The ultrasonic transmitters and receivers the ultrasound may be placed in rollers to facilitate high-speed, in-line processing of wooden members.
Patent CA-2389410-A1 (CA)
Inventor: THYAGARAJAN KADAYAM
IPC: H04N19/122
Filed: 2000-11-08
Abstract: A system and method for image compression utilizing adaptively sized blocks and sub-blocks of discrete cosine transform coefficient data is presented. A  block size assignment element in the encoder selects the block or sub-block of an input block of pixels to be processed. The selection is based on the variance of pixel values. Blocks with variances larger than a threshold are subdivided, while blocks with variances smaller than a threshold are not subdivided. A transform element transforms the pixel values of the selected blocks into the frequency domain. The frequency domain values may then be quantized, serialized, and variable length coded in preparation for transmission.

Title: Template driven creation of promotional planning jobs
Inventor: PALMS GRANT C
IPC: G06Q10/06
Filed: 2003-04-30
Abstract: A method and system are presented for creating promotion planning jobs that can be implemented in a workflow management system. Templates set forth specific tasks that will be implemented to perform the job. Tasks are assigned to a predefined role. Users of the system are assigned to roles, and then grouped together into teams. Each team is associated with a particular class. A team of users generally contains one user for each role needed to complete a job. A job is created from the template and assigned a class. A team is then selected based on this class. Users that make up that team are then assigned to the particular task based upon the users' role and the role assigned to the task by the template. If a job is assigned to multiple classes, multiple teams will be assigned to the job. A master template allows multiple promotions to be coordinated. Jobs created from master templates have preliminary tasks that are generally performed before the tasks associated with jobs created from related sub-templates.
