The plate (10) is then flood-cured with UV radiation and washed to better expose the hardened image structure areas of the UV curing layer (14)  which have formed and which provide the cells (18) for holding the printing ink for use in the gravure printing process.
Patent CA-2368131-A1 (CA)
Title: Canoe and kayak mid-point sponsons safety
Inventor: INGRAM ROBERT TIMOTHY
IPC: B63B43/14
Filed: 2002-01-14
Abstract: Canoe and kayak mid-point sponsors attach to the canoe or kayak only at the mid-point of the sponsors, to enable the sponsors to rotate around the midpoint in order to reduce drag in waves and simplify attachment and detachment to the canoe or kayak. They create greater sponsor buoyancy and stability than any other type of sponsor, without interfering with normal paddling to safety. They are attached to any canoe or kayak by material such as only one adjustable strap and two clips, extending to kayak deck fittings adjacent the cockpit or a canoe middle thwart, in such a manner as to facilitate normal paddling of the stabilized craft in life threatening emergencies. They can be directly attached to both sides of the hull near the waterline. The mid-point sponsors can be solid buoyant material, waterproof and airtight stowage bags containing bulky lightweight items such as sleeping bags, orally inflatable sponsor floats, and gas cartridge inflatable sponsor floats. A  particular feature is permanent or semi-permanent attachment to the hull above the waterline to eliminate drag unless inflated, in which case the inflated sponsors are forced to immerse in the water. When not inflated each midpoint sponsor is neatly stowed in a small and rescue-emergency marked stowage bag or covering that holds sponsors upward from the waterline. Such an arrangement ensures that the sponsors rest sleekly and unobtrusively along the hull side when not deployed.

Title: Apparatus and method for measuring polarization dependent loss
Inventor: SUMMA MARK A
IPC: G01M11/02
Filed: 2000-04-07
Abstract: An apparatus for measuring polarization dependent loss is disclosed featurin g several fiber optic couplers combined in tandem and oriented such that the P DL noise of the measurement system is reduced to a negligible level. By matchin g the PDLs of the couplers and vectorally subtracting opposite phases of polarization, the PDL of the measurement system is virtually eliminated. Thu s, the PDL noise floor is lowered to near zero and the PDL of the optical devic e- under-test (DUT) can be accurately measured. The system is relatively inexpensive to implement and offers needed versatility because it measures t he PDL of optical devices that operate in a reflection mode or in a forward transmission mode. Thus, it provides one PDL measurement solution for both types of devices.

Patent CA-2371646-A1 (CA)
Title: Configuration model for configuring an adapter software component to selectively access software objects and object editor using instance of same
Inventor: SETO NORMAN K
IPC: G06F9/44
Filed: 2002-02-13
Abstract: An object editor capable of displaying a set of application software objects, which may include objects with a dynamic reflection capability ("reflective objects"), includes an object oriented configuration model instance (CMI), a generic adapter, and a UI framework. The CMI is particular to the set of application objects to be edited and defines a particular view of these objects to be provided by the editor. The CMI is external to the generic adapter and includes settings that control which application objects will be accessed and the manner of access, and in particular, which application objects will be visible, which of the visible objects' attributes will be displayed, the arrangement of displayed application objects and attributes, and the appearance of the displayed objects and attributes. The CMI is stored as a serialized XML file. The generic adapter reads the de-serialized CMI's current settings, selectively accesses the set of application objects to be edited and their attributes as dictated by the CMI settings, and passes the accessed information to the UI framework for display. The adapter uses reflection to access the attributes and associations of reflective objects. The CMI settings may be changed between editor invocations to cause objects or their attributes to be accessed and displayed differently, or not at all. The editor may be configured to edit a new set of software objects by substituting a new CMI corresponding to that set of objects. A CMI and generic adapter may be used in conjunction with applications other than an object editor, in which case the CMI settings define a manner of selectively accessing the application objects and may affect the operation of the application.

Patent CA-2376014-A1 (CA)
Inventor: HOOLE ELLIOTT
IPC: H04L25/03
Filed: 2000-06-09
Abstract: A method is provided for minimizing the peak power level in a combination of orthogonal frequency division multiplexed (OFDM) tones. The method is particularly effective when the information to be communicated is digital data consisting of long patterns of "1"s or "0"s. The digital data of the message is combined with a scrambling vector before the data is modulated. The randomization of data patterns, in turn, leads to a more random combination of OFDM tone amplitude being transmitted. The message is recovered at the receiver by removing the scrambling vector. A  table of scrambling vectors is maintained at the transmitters and receivers. The table pointer to select the scrambling vector is selected in response to the position of the message in the communication structure. An OFDM communication system using the above-described method is also provided.

Title: Circuit and method for live switching of digital video programs containing embedded audio data
Inventor: PLAUNT ALAN
IPC: H04N21/44
Filed: 2002-03-28
Abstract: A circuit for detecting a transition in the content of a digital video stream containing embedded audio samples and providing a smooth transition from an old audio stream embedded before the transition to a new audio stream embedded after the transition. The circuit detects the transistion and in response it fades out the old audio stream and fades in the new audio stream. During the transition, the old and new audio signal are buffered. The old stream is not faded out until only a number of audio samples required for the fading process remain in the associated buffer.  The new audio stream is not faded in until a selected number of audio samples have been stored ~ the associated buffer. The selected number of samples is typically smaller than the number of samples that is desirably stored in the associated buffer during steady state operation. An interpolation operation is used to allow the number of new audio samples in the associated buffer to build up to the desired number.
