Abstract: Cette invention se rapporte à un diviseur de tension photosensible (10 ou 240), qui comprend un dispositif photosensible (12A). De préférence, deux dispositifs photosensibles connectés en série (12A et 12B) et deux résistances (14A et 14B) sont utilisés pour former un diviseur de tension photosensible (10) qui non seulement est équilibré du point de vue des lumens mais qui également est capable de fournir une tension nulle en l'absence de lumière. Un transducteur assorti proportionnel (82, 148 ou 161) comprend l'un de ces diviseurs de tension photosensibles (10), une lampe (57 ou 126) comme source de lumière, et des moyens (78, 132 ou 166) permettant de réguler sélectivement la transmission de lumière à partir de la lampe (57 ou 126) à destination du diviseur de tension photosensible (10 ou 240). Une unité de commande X-Y à manche du type levier de commande (48 ou 160) comprend deux des diviseurs de tension photosensibles (10). Un levier de commande (58 ou 164) active une surface miroir (78) ou un obturateur lumineux (166) pour commander la transmission de lumière de la lampe (57 ou 126) vers les deux diviseurs de tension photosensibles (10 ou 240). Une unité de commande X-Y sensible à l'inclinaison (102) comporte deux des diviseurs de tension photosensibles (10 ou 240), et un fluide photolimitateur (132) limite sélectivement la transmission de lumière de la lampe (126) vers les diviseurs de tension photosensibles (10 ou 240) en fonction des angles d'inclinaison (146). Un commande sélective de la proportionnalité est obtenue par atténuation de l'intensité de la lampe (57 ou 126). Un commande sélective du démarrage et de l'arrêt est obtenue par régulation sélective de la vitesse de variation des lumens produits par les lampes (57 et 126) et une régulation sélective de la vitesse de variation des lumens est obtenue par limitation de la vitesse d'augmentation et de baisse des tensions appliquées à la lampe (57 ou 126).

Title: Method and apparatus for performing internet protocol address resolutions in a telecommunications network
Inventor: OSMAN GHASSAN M
IPC: H04M3/42
Filed: 2000-05-17
Abstract: A method and apparatus for performing directory number/Internet Protocol (IP) address resolutions to facilitate voice over IP communications. A message requesting the IP address of an IP gateway is built at an originating Time-Division Multiplex (TDM) switch (that forms part of either a private or public network). The message is forwarded over a TDM telecommunications network to a terminating TDM switch, where the requested IP address information is retrieved. The IP address is forwarded across the TDM telecommunications network to the originating TDM switch. The IP address is then used to establish a call across an IP network. By using existing TDM protocols and infrastructure to request and retrieve IP gateway information, the present invention does not suffer from the scalability problems inherent in other DN/IP address resolution solutions.

Title: Clip on manifold heat exchanger
Inventor: DECAIRE CARL C J
IPC: F28D1/03
Filed: 2000-06-02
Abstract: A plate and fin type heat exchanger is disclosed which can be made in any convenient size with minimum tooling required. The heat exchanger is made from a plurality of stacked plate pairs having raised peripheral edge portions to define flow channels inside the plate pairs. The plates of the plate pairs are formed with offset, diverging end flanges that space the plate pairs apart. A U-shaped channel envelops the plate end flanges to form part of a manifold at each end of the plate pairs. End caps or plates close the open ends of the U-shaped channels to complete the manifolds, and inlet and outlet openings are formed in the manifolds as desired to complete the heat exchanger.

Patent CA-2315739-A1 (CA)
Title: Improvements in or relating to radar systems
Inventor: BAKER JONATHAN HOWARD
IPC: G01S13/524
Filed: 1999-02-15
Abstract: In a radar system it is necessary to dis-tinguish signals reflected from wanted targets such as aircraft from those reflected from fixed terrain features, known as clutter. The clut-ter signals can in some cases be significantly stronger than the wanted signals. One method for dealing with land clutter is the use of a high resolution clutter map. The area around the radar is considered to be divided into cells, and an array of background signal estimates is maintained for these cells. Whenever a signal is received by the radar, it is compared with the stored background level for the cell it oc-cupies, and a detection is only reported if the signal exceeds the background by a pro-set threshold. Received signals are also used to modify the stored background levels so that the clutter map adapts to the reflections from clutter which are present over long periods. Clutter maps have so far only been used successfully for radars at fixed locations. In the case of a shipborne radar near land, a conventional clutter map will not work well.  This is because as the ship moves, the positions of land scatterers relative to the ship will not be fixed. Individual terrain features will therefore be moved from one clutter map cell to another.  In the cell into which a strong scatterer moves, the land clutter reflections will be reported as targets until the stored background has had time to adapt to the new higher level. Similarly, in the cell which the scatterer has left, the stored background level will be higher than necessary, and may cause actual targets to be suppressed until it has had time to adapt to the new lower clutter level. The method of operating a radar system in accordance with the present invention provides compensation of ship movement so that fixed terrain features always stay within the same clutter map cell, periodically re-centering the clutter map so that its origin of co-ordinates does not depart too far from the actual ship position. Two separate clutter maps are used so that one can be re-centered and initialised (filled with suitable background estimates) whilst the other is in use for determining radar detections. A method for accelerating the initialisation time so that re-centering can be achieved sufficiently often during rapid movement is provided, and the updating of cell background levels is combined with the detection process in order to streamline the process and reduce computational load.

IPC: B26D7/22
Filed: 2001-01-25
Abstract: A hand tool for forming circular cutouts of sheet material secures the material so that no generally central penetration in the form of a pilot hole or the like, is required. The resulting cutout is useful in the construction of an article assembled from a series of such blanks or cutouts, such as a quilt assembled from a large number of blanks with the blanks being sewn together at points of mutual contact about their circumferences. The tool comprises a relatively stationary base hub with a shaft extending upwardly therefrom, and a hand pressure knob mounted on the shaft opposite the base hub. A rotary disc with a radial channel having a cutting arm and rotary cutting blade therein, is sandwiched between the base hub and pressure knob. The tool is placed upon the sheet material and pressure is applied to the pressure knob, with the cutting arm and rotary disc being rotated about the hub and knob to drive the cutting blade in a circular path about the hub. The uniform pressure of the rotary disc upon the sheet material being cut ensures that the material cannot gather or deform due to pressure from the cutting disc, thereby providing an accurate circular cutout of material. The cutting disc is adjustable along the cutting arm to provide a wide variety of cutting diameters as desired. The tool is particularly well adapted for cutting fabric materials, but may be used to cut a wide variety of other sheet materials as well.
