Patent CA-2254593-A1 (CA)
Inventor: SOLHEIM ALAN GLEN
IPC: H04J14/02
Filed: 1998-11-26
Abstract: A method and apparatus for channel performance equalization in wavelength division multiplexed (WDM) systems is disclosed. Performance of the channels is estimated from optical power measurements of each signal transmitted by the channels. The measurements are taken at the inputs of optical amplifiers in the transmission path of the system. The channels are equalized by adjusting the optical power of the channeltransmitters. The method is applicable to point-to-point networks as well as more complex network configurations such as those having an add-drop multiplexer (ADM) for inserting and extracting channels from the transmission path. The method can compensate for signals having different bit rates by applying an offset to the amount of optical power adjustment of the channel transmitters. Furthermore, if different types of optical amplifiers are used in the transmission path, the method can accommodate different noise characteristics of the amplifiers by using their noise figures in determining the amount of optical power adjustment of the transmitters that is required to equalize channel performance.

Abstract: An accessory key chain composition of frame and DNA storage unit, serving a useful function as photo holder and hair container, providing visual data as well as DNA data needed for future possible reproduction. Said entity is comprised of two fused complimentary parts making one key chain frame of multiple functions and purpose. With a cylindrical test-tube appearing container, and a square frame-like holder, an individual may carry an appropriate image of an animal or human, and it's appropriate DNA information available in a hair strand. Thus, an individual has all necessary visual and biological information, within close proximity to oneself, of his loved one, to be able to reproduce said loved one in the future once readily accepted by the public.  With the DNA reproduction process already proven, this will enable any individual to carry the photo of their loved one, being a human being or favourite pet, and have the necessary data on hand at any time for reproduction, and in having a sense of a loved one nearby, keeping keys in hand as well as a link to the individual's key persons or animals in his/her life.
Patent CA-2260848-A1 (CA)
Title: Laterally expandable tampon and a method of forming the tampon
Inventor: PAALMAN DONALD HENRY
IPC: A61F13/20
Filed: 1997-07-09
Abstract: A tampon and a method of forming the tampon are disclosed. The tampon is useful in preventing premature leakage of body fluid from a woman's vagina, especially during her menstrual period. The tampon includes an absorbent and a liquid-permeable cover. The cover at least partially surrounds the absorbent and together they form an elongated softwind having a first end and a second end. The softwind is folded upon itself at three spaced apart locations to form an M-shape profile. The M-shape profile is then compressed into a cylindrically shaped pledget having an insertion end and a trailing end. The insertion end contains a greater amount of absorbent than said trailing end and has a cleft formed therein as a result of the folding. The cleft causes the pledget to lateral expand immediately upon insertion of the tampon into a woman's vagina. The tampon further includes a withdrawal string which facilitates removal of the tampon from a woman's vagina.

Title: Network architectures with transparent transport capabilities
Inventor: NICHOLSON DAVID JOHN
IPC: H04J3/08
Filed: 1999-02-11
Abstract: Architectures for a synchronous transport network of a telecommunications system using transparent transport capabilities are presented. The telecommunications network comprises a pair of transparent multiplexers (TMuxs) connected over a bidirectional high speed span for transparently transporting high rate traffic. Each TMux consolidates traffic from a plurality (I) of linear systems or a plurality of bidirectional self-healing rings, each ring (K i) having a ring rate Ri and at least two nodes (A i, B  i). In another configuration, each TMux subtends a plurality of rings, such TMuxes being adapted for connection as ring nodes in a high-speed ring. The upgrades obtained with TMuxes in both the linear and ring configurations provide for per span relief for fiber exhaust where no changes to the existing systems are desired. As well, the bandwidth of an existing system may be increased on a per-span basis or the equipment count may be reduced.

Title: Transcoding system using encoding history information
Inventor: MURAKAMI YOSHIHIRO
IPC: H04N19/40
Filed: 1999-03-05
Abstract: The present invention provides a transcoder for changing a GOP structure and the bit rate of an encoded bitstream obtained as a result of an encoding process based on MPEG standards. According to the transcoder provided by the present invention, encoding parameters generated in a past encoding process can be transmitted to the MPEG encoder which performs a present encoding process as a history information. And optimum encoding parameters in commensurate with the present encoding process are selected from the transmitted encoding parameters, and the selected encoding parameters are reused in the present encoding process. As a result, the picture quality does not deteriorate even if decoding and encoding processes are carried out repeatedly.

Patent CA-2276601-A1 (CA)
Inventor: ANDERSON SCOTT V
IPC: F16H63/44
Filed: 1999-06-29
Abstract: An integrated system for automatically controlling the operation of both an automated manual transmission and a multiple speed axle assembly in a vehicle drive train assembly includes a transmission actuator for operating the transmission in any one of a plurality of transmission gear ratios. The system further includes an axle actuator for operating the axle assembly in any one of a plurality of axle gear ratios. An electronic controller is provided for operating the transmission in a desired one of the plurality of transmission gear ratios and for operating the axle assembly in a desired one of the plurality of axle gear ratios to provide a desired overall gear ratio for the vehicle. To accomplish this, the electronic controller is responsive to one or more input signals that represent operating parameters of the vehicle. When it is determined that a change in the overall gear ratio of the vehicle is necessary, the electronic controller operates one or both of the transmission actuator and the axle actuator to achieve the desired overall gear ratio. The determination of whether the transmission actuator alone is actuated, the axle actuator alone is actuated, or both the transmission actuator and the axle actuator are actuated will depend upon the specific gear ratios provided by the transmission and the axle actuator, the current overall gear ratio, the desired overall gear ratio, and other factors. The system can also be adapted for use with an automatic transmission and with a variable speed motor, such as an electric motor, that is connected directly to the axle assembly without an intervening transmission.

Title: Hydraulic controls for agricultural implements
Inventor: FRIGGSTAD TERRANCE A
IPC: A01B73/00
Filed: 1999-11-10
Abstract: An agricultural implement, having ground engaging tools mounted on subframes that are movable through hydraulic actuators between raised transport and lowered working positions, is provided with a hydraulic circuit in which the actuators are connected in parallel with one another within a grouping of the actuators. The positioning of the ground engaging tools into a lowered working position closes the hydraulic circuit for the group of actuators. The subframes are arranged to float over ground undulations to maintain a common working depth for the ground engaging tools. The vertical movement of any one of the actuators in the common group will force a displacement of a corresponding amount of hydraulic fluid, which will then be shared by all of the remaining actuators in the corresponding group. A depth averaging control for the ground engaging tools and a mechanical headland stop apparatus are also provided for the agricultural implement.
