Patent CA-2210784-A1 (CA)
Inventor: BAUCELLS GRANELL JAIME
IPC: A45C13/10
Filed: 1997-07-17
Abstract: Seal for bags and the like designed to carry out the attaching of the operating tongue of a zipper making up the fastening means of a bag or the like, the seal made up from a flattened channelled-shaped base body provided with undetachable fastening means for said bag or the like, said body having a narrowing associated to one of the ends of its mouthpiece, in a way such that this mouthpiece takes a shape matching with that of said tongue, which is being engageable to said mouthpiece, using the groove-tongue effect, allowing only a frontal engagement which is longitudinally locking both components. Also the spline of the base body has a higher depth  than the tongue's thickness and incorporates some supports for said tongue, these supports defining a coplanar position between the tongue and the mouthpiece of the base body; in this position both components are lockable by means of a third part making up the seal and being concurrently engageable to the former ones (figures 7 and 8).

Title: Node configuration setup system with servers hunting through connection-oriented network for client's data
Inventor: YAMANO SHIGEKI
IPC: H04L12/46
Filed: 1997-09-19
Abstract: A node configuration setup system comprises a configuration client node connected to a connection-oriented network, and a number of configuration server nodes interconnected via the network. A first configuration server node is responsive to an initial configuration inquiry message from the client node for returning a ready-to-accept message if it holds the client's configuration data.

Patent CA-2220760-A1 (CA)
Inventor: KAISER MANFRED
IPC: H04B1/74
Filed: 1997-12-01
Abstract: An optical switching unit is disclosed which permits switching from faulty components to standby components in optical transmission systems. A component in this connection may be a transmit laser or an optical fiber, for example. The optical switching unit (OSE) according to the invention contains an n x m optical space switch (ORS) whose ports (P1A...PNA; P1B...PMB) are monitored by photodiodes (M1A, M1B). The photodiodes provide a control unit (SE) with information as to whether and, if so, what signals are arriving at the ports. The control unit (SE) controls the position of the optical switch (ORS) in accordance with program instructions. The switching unit controls itself, i.e., incorporation of a higher-level control center is not necessary. It thus allows very short switching times and has many applications; it is particularly suitable for use in modular optical transmission systems.

Patent CA-2249503-A1 (CA)
Inventor: BACON EDWARD M
IPC: B60W30/19
Filed: 1998-10-02
Abstract: A dithering torque control method that is useful for a semi-automated vehicle transmission facilitates accomplishing a desired condition in the transmission. The method is useful during an initial break torque function to relieve drive train torque so that a driver can move a manual shift lever from an engaged position to a transmission neutral position without using a clutch. The method is also useful for shifting a lever to move gearing components from a neutral position to a next desired gear. A dithering function is used to cyclically oscillate a current torque value about a target torque value that is associated with the desired transmission condition. An amplitude and period of the dithering function are determined based upon an overall gear ratio of the transmission. The dithering function begins at a point dependent on a torque value associated with the currently engaged gear. The dithering function continues until a known transmission condition is confirmed.
Patent CA-2254305-A1 (CA)
Title: A laser module allowing simultaneous wavelength and power control
Inventor: GARIEPY DANIEL
IPC: H01S5/0687
Filed: 1998-11-16
Abstract: An apparatus for simultaneously stabilising the output power and wavelength of a semiconductor laser is disclosed. A wavelength discriminating scheme is used to provide a wavelength error signal and an output power detection scheme is used to provide an output power level signal. The wavelength error signal is used to adjust the behaviour of a temperature sensor such that an automatic temperature control (ATC) module configured to maintain a pre-determined output from the temperature sensor, adjusts the actual laser temperature to minimise said signal. The output power level signal is directly delivered to an automatic power control (APC) module, which adjusts the drive current fed into the laser to minimise said signal using known control circuitry means. Adjusting the properties of the temperature sensor makes it possible for the apparatus to manipulate laser temperature and current to achieve simultaneous power, wavelength and temperature control, using the constant-temperature and constant-power external control modules used by semiconductor lasers that do not stabilise wavelength.
