Filed: 1993-04-21
Abstract: On produit des valeurs d'ombrage pour les sommets d'un polygone découpé par un volume de vue sans qu'il soit nécessaire d'effectuer de calculs d'éclairage inutiles pour les polygones situés tout entiers à l'extérieur de ce volume de vue.  Chaque sommet de polygone subit une transformation et une vérification afin de déterminer s'il se trouve ou non dans le volume de vue.  Si un sommet vérifié se trouve dans le volume de vue, on procède pour celui-ci à des calculs d'éclairage.  Si le polygone se situe entièrement à l'extérieur du volume de vue, on n'effectue pas de calculs pour le sommet de ce polygone, et l'on n'exécute qu'un sous-ensemble du calcul de transformation de ses coordonnées.  On procède aux calculs de transformation et d'éclairage complets pour les sommets situés à l'extérieur du volume de vue dans le seul cas où c'est indispensable pour déterminer par interpolation les valeurs des nouveaux sommets obtenus par découpage.

Title: Plant fertilizer and pesticide sprayer apparatus
Inventor: MUNSEY ROSS N
IPC: A01M21/04
Filed: 1993-07-16
Abstract: ABSTRACT OF THE DISCLOSURE         In an effort to give a conifer seedling a chance to grow, it is common practice to apply fertilizer to the seedling itself while spraying a herbicide onto the area around the seedling.  Both of these tasks can be arduous and time consuming especially in view of the nature of the terrain where seedlings are planted.  Uncontrolled herbicide application can harm the seedling as much as the weeds.  The present invention provides a device, which is easy to manipulate manually, and which enables the user to apply fertilizer to the seedling while simultaneously applying herbicide to the area around the seedling.  The invention also provides a shroud for protecting the seedling while herbicide is being sprayed therearound.

Patent CA-2119602-A1 (CA)
Inventor: FOURNIER THOMAS J
IPC: G01M3/32
Filed: 1994-03-22
Abstract: An apparatus and method for the non-intrusive testing of evaporative fuel vapor systems of motor vehicles.          A portable pressure control and monitoring unit is inserted into the fuel filler neck of a vehicle. The vapor vent line, leading from the fuel tank to the charcoal canister of the evaporative system, is temporarily clamped off.          Pressurized gas is introduced into the unit from an operator's console, expanding a ring bladder and sealing an annular volume between the unit and the filler neck. Gas is then passed through the unit into the contained volume of the evaporative system. After the neck cap is replaced, an automatic timer deflates the ring bladder, charging the remaining volume of the evaporative system. Pressure decay data is collected and stored in the unit's digital storage device Initially, this data is used in a pass/fail determination made by a microprocessor in the unit. Later, the data is downloaded into a separate computer for archival purposes.

Title: Device for testing the operability of speed-measurement devices used in traffic control
Inventor: GROSS MARIO
IPC: G08G1/054
Filed: 1993-04-29
Abstract: Stationary speed-measurement devices used in traffic control have sensors laid in the road surface which react to vehicles that pass over them and which generate speed measurement values; when an admissible speed limit is exceeded by a vehicle driving over the sensors, a picture of the vehicle is taken by a camera. In order to test the operatability of such speed measurement devices, error recognition means prevent the speed measurement values from being taken into account when certain error criteria occur.  Counters are provided for counting the frequency of occurrence of error criteria. A determined statistical distribution of the occurrences of the various error criteria results for each installation.  When deviations from this distribution are detected, that means that the installation needs to be modified.
