Title: Gas sensor
Inventor: MARTIN HANS GOERAN EVALD
IPC: G01N21/05
Filed: 1997-08-20
Abstract: The invention relates to a gas sensor (A) which is adapted for evaluating the contents of a gas sample enclosed in a cavity (2) or a gas cell (1). The gas sensor has the form of a block in which the wall or wall-parts of a gas cell or cavity have highly light-reflective properties, designated minor surfaces (11A, 12A). The cavity (2) has an opening (2a) for incoming light rays which are reflected in the cavity a predetermined number of times such as to create an optical analysis path before being caused to pass through an opening (6) for outgoing light rays, such reflections being achieved with the aid of three opposing, concave light-reflecting wall-parts (11, 12, 13).      A first of the light-reflecting wall-parts (11) has the shape of part of an ellipsoid. A second (12) and a third (13) of the light-reflecting wall parts have a common shape conforming to part of an ellipsoid. The focal points (11a, 11b) for the first light-reflecting wall-part (11) are disposed in or close to mirror surfaces (12A, 13A) for the second (12) and the third (13) wall-parts. A focal point (12a) for the second wall-part (12) and a focal point (13a) for the third wall-part (13) are located in or close to the minor surface (11a) of the first wall-part (11).

Title: Migration of routing number selection to the base station controller of a cellular telephone network
Inventor: SAWYER FRANCOIS
IPC: H04M3/00
Filed: 1997-11-25
Abstract: Responsive to receipt at an originating switching node (52(1)) of an incoming call (200), a location request (send routing) message (202) is sent to the home location register (60) for the called mobile station (54(1)). A routing request (provide roaming) message (204) is then sent from the home location register to the switching node (52(2)) identified by the home location register as currently serving the called mobile station. The serving switching node then sends a routing number request message (208) to the base station controller (64(2)) currently serving the called mobile station. The base station controller then assigns an appropriate one of its routing numbers (218), and responds (220, 222) back to the originating switching node via the home location register and the visited switching node with the assigned routing number. The assigned routing number is then used to establish a trunk connection (224) between the originating switching node and the base station controller for purposes of effectuating call delivery. Alternatively, the serving switching node makes the selection of the base station controller assigned routing number (218').

Title: Internally calibrated oxygen sensor, method and system
Inventor: MEYER EMILIO
IPC: G01N27/409
Filed: 1999-06-01
Abstract: A zirconium oxide shell forms a chamber of fixed volume, and a controller monitors voltage across the shell indicative of the difference between inside and outside oxygen levels, applying a signal to pump oxygen. Integrated pump current yields a measure of the oxygen added to or removed from the chamber. The sensor material is a mixture of about 91% zirconium oxide and 9% yitrium oxide, with porous electrodes on each surface. The controller may apply a sequence of current pulses, checking the Nernst cell output indicative of .DELTA.P across the wall, until .DELTA..P=0. Positive and negative pulses may be tallied in a running sum to determine the present reading. The processor adds the present differential as a correction to the last stored reading to provide the oxygen level as an immediate output.
Patent CA-2274561-A1 (CA)
Inventor: DEYOUNG THOMAS
IPC: G01N35/00
Filed: 1999-06-07
Abstract: The stat shuttle adapter and transport device includes a conveyor with a movable platform for securement of the stat shuttle adapter. The stat shuttle adapter is a universal holding device that includes a carrier housing having male and female surfaces that engage complementary shaped female or male surfaces of a rack that is held by the carrier housing. The conveyor has a forward load position wherein racks are loaded onto the carrier housing. The conveyor also has a rearward unload position wherein the loaded rack is locked onto the carrier housing to facilitate removal of the contents of the rack from the carrier housing without upsetting the rack. A latch device on the carrier housing is normally biased to a lock position but is maintained in an unlock position when the carrier housing is at the forward load position of the conveyor. A latch engagement device on the conveyor maintains the latch in the unlock position while the carrier housing is at the forward load position of the conveyor. Once the conveyor moves the carrier housing away from the forward load position toward the rearward unload position the latch device is free to move to the normal lock position wherein the loaded rack is locked to the carrier housing. As the conveyor moves the carrier housing toward to the rearward unload position the latch device remains in the lock position. To ensure that the latch device is in the lock position when the carrier housing is at the rearward unload position a latch actuator surface is provided at the rearward unload position of the conveyor to move the latch into the lock position if for some reason the latch remains in the unlock position.

Title: Window washer nozzle assembly having a favorable spray pattern
Inventor: KONDO TAKATOSHI
IPC: B05B1/10
Filed: 1999-08-06
Abstract: In a washer nozzle assembly, the upper lip portion defining a nozzle opening extends more forwardly than the lower lip portion so that the part of the washer liquid directed upward is blocked by the longer upper lip portion, and the upper part of the spray pattern includes more liquid droplets of larger sizes as compared to the prior art. Thus, the loss of washer liquid by being flown above the windshield at high speed can be reduced, and the spray pattern of the washer nozzle assembly can be optimized for all speeds.
