Title: Golf club with titanium head and plastic hosel
Inventor: NOBLE RANDALL B
IPC: A63B53/02
Filed: 1998-11-17
Abstract: A golf club commonly referred to as a "driver" includes a head made of titanium and a hosel made of plastic. The head includes a hollow body, and the hosel has a lower portion inserted into a bore in the head and an upper portion extending upwardly from a top wall of the hollow body. The bore has an open top end that is substantially flush with the body top wall and a closed bottom end that is spaced from a bottom wall of the hollow body. A passage extends through the upper and lower portions of the hosel and receives a tip end of a shaft that is preferably made of graphite. Since the hosel is made of softer material than the head, the hosel has a cushioning effect on the shaft which reduces the amount of vibration transmitted to the shaft. The hosel lower portion has an irregular outside shape and the bore in the head has a complementary irregular inside shape so that the hosel may be inserted into the bore in only one orientation to ensure exact alignment of the shaft relative to the head.

Patent CA-2259743-A1 (CA)
Title: Dryer control system
Inventor: DENNIS STEPHEN
IPC: B28B11/24
Filed: 1999-01-18
Abstract: A control system and method for a dryer used to dry a line of gypsum boards.  The control system automates control of the dryer by measuring the amount of water used at the mixer to produce board segments and determining a desired amount of water to be evaporated for each board segment based on the measured value. The desired amount of water to be evaporated for each board segment is tracked through the production line and the total evaporation load of each dryer zone is continuously calculated based on the board segments located in the dryer zone at a given time. The dryer zone differential temperature is adjusted according to the calculated evaporation load. When a board is rejected from the board line, the desired amounts of water to be evaporated of its corresponding board segments are set to zero, thus signifying a gap. The control system can be implemented using a distributed control concept, with PLC's controlling major process areas, and networked PC based supervisory operator interfaces located at key locations throughout the production line.

Abstract: Image data representing a moving image by a sequence of image frames each containing an array of pixels. A distinctive characteristic of an image frame is identified and image data is modified in response to process iterations. For each iteration, a tracking parameter is generated (1504) and the rendering of said object is controlled (1506) in response to the tracking parameter. An output image is displayed in response to the application of the controlled object so that tracking and display operations are performed on a frame-by-frame basis to facilitate creative manipulation of control parameters and tracking locations.
Patent CA-2267587-A1 (CA)
Inventor: HUMPHREY LESLIE D
IPC: H04L12/70
Filed: 1999-03-31
Abstract: To reduce the effects of cross-talk in, principally, a wireline communication system (10), idle cells usually required for rate adaptation (32) are substituted by null cells (36) and sequence scrambling (40) required for data protection and associated with traffic is abandoned in relation to the null cell. Subsequent modulation (48) of each null cell is further restricted in the sense that a transmitted power associated with the null cell is, preferably, minimised. In this latter respect, minimum power is achieved within a modulation scheme through a two-stage process. First, a zero level state is selected within a symbol constellation of the modulation scheme (100), and then a confidence level associated with recovery of the zero level state is enhanced by always sending zero values as at least pairs of associated symbols. A receiver (14) then only interprets incoming data as a null cell or the zero level state when all associated symbols are recovered as the zero value. Hence, a metric distance (146) between the zero level state (140) and any other symbol state (102-132) in the constellation (100) is increased to unity by a multi-dimensional presence of the zero level state.

Title: System and method for capturing document style by example
Inventor: MCKNIGHT DAVID K
IPC: G06F17/21
Filed: 1999-10-15
Abstract: A system and method of using an example document to create another document with the same style. The style is determined by examining the example file for syntax patterns that are required in a document of this type. Each pattern is used to create a section template (a sub-template for a larger template). After all the required sub-templates have been defined, by examining the example, we have a document template that may be used to format new documents.  Along with user-specific content, a document generator uses the captured document template to generate sections of a new document. When a section of a document is generated, the sub-template that corresponds to that section of a document is inserted with user-specific content. The generated file ends up with the same kind of text spacing and positioning, ordering of sections, presence of annotations and other nonfunctional attributes as the example.
