IPC: G06T7/60
Filed: 1990-11-09
Abstract: ABSTRACT OF THE DISCLOSURE      A system (82) and method for locating features in an image.  In the preferred embodiments, the present invention accepts as input a tilted view X-ray image of a PC board (10), as well as expected locations of solder joints (18) in the PC board (10).  The present invention then determines the actual center locations (32) of these solder joints (18) by defining windows within the image and checking individual areas within the window, to see if they fall below a predetermined threshold.  In addition, the system (82) determines if these pixels are connected to other pixels that have been previously determined to be part of the solder joint (18).   Finally, the system (82)  determines the center of the group of pixels determined to be part of the solder joint and displays the coordinate location of this center.

Patent CA-2034754-A1 (CA)
Title: Controllable recloser for power line
Inventor: DUNK MICHAEL
IPC: H02H1/06
Filed: 1991-01-22
Abstract: An electronically controlled recloser for an electrical power distribution system is powered by at least one current transformer coupled to give an output in response to power line current. A voltage is stored on a large and a small capacitor in response to the line current and is compared with a reference voltage for determining the level of line current. When abnormally high levels of current appear on the line, it is opened for a short period of time. The energy stored on the capacitors is supplied to power the recloser during low line current conditions. At an end of a given time period following the opening of said line, the recloser recloses the line. If the abnormal condition persists, the recloser again opens and closes the line. When there is a surge of line current, the large capacitor is effectively removed from the circuit so that a response will not be delayed while the large capacitor charges; therefore, the charge on the small capacitor provide a quick start for immediate response. The circuit includes a novel circuit for converting a level of line current into a frequency which may be used by a microprocessor for selecting a mode of operations.

Abstract: In a key telephone system in which a plurality of data terminals 371 ... 37n such as personal computers are connected to a key service unit 1 connected to a plurality of telephone lines 251 ... 25m, a modem 43 is pooled so as to be usable in common for the plural data terminals 371 ...  37n.   In response to a called party number signal from the Telephone line (e.g. 251), the key service unit 1 selects a single data terminal among the data terminals 371 ... 37n now being in standby status, and closes a communication channel between the selected data terminal  (e.g.  371)  and the modem 43,  so that a status  equivalent  to  that  where  the  selected  data terminal 371 and the modem 43 are directly connected to each  other  can  be  established.    Thereafter,  the  key service unit 1 indicates a called party number signal reception to the modem 43, and the modem 43 transmits a call  to  the  selected  data  terminal  371.    When  the selected data terminal 371 responds to the call from this modem 43, the key service unit 1 closes a communication channel between the modem 43 and the telephone line 251, so that a communication link between the selected data terminal  371  and  the  telephone  line  251  can  be established via the modem 43.   During the process until this communication link can be established,  since  the selected data terminal 371 and the modem 43 are in the status equivalent  to direct  coupling,  the key service unit 1 is not concerned in the communications between the selected  data  terminal  371  and  thus  modem  43,  thus reducing the operational load applied to the key service unit 1.

Title: Method of erecting the outer walls of a building, and a building
Inventor: WOLFF IB V
IPC: F28D20/00
Filed: 1990-01-31
Abstract: ABSTRACT      A building where steel plates are used partly as heat transporting elements to and from the heat magazine and constant heat area of the earth and partly as load-bearing elements.   The  steel plates maintain a  significantly higher surface temperature than the outer walls of a conventional  building  in  the  winter,  and  they  are insulated on the inner side to below ground level with a high  insulation value,  thereby making it possible to maintain stay temperature in the interior of the building because of the free heat from the stay and activities of a few individuals as well as from incident sunlight and heat recovery device in connection with air change.   In the summer, the steel plates serve as air condition by conducting excess heat down into the ground.  They may be insulated on the outer side to restrict heating owing to incident sunlight.  This insulation also reduces the need for thermal energy from the earth magazine in the winter.
