Patent CA-2244575-C (CA)
Title: Oxygen sensor
Inventor: OOKAWA TEPPEI
IPC: F02B77/08
Filed: 1998-08-06
Granted: 2006-09-26
Abstract: An oxygen sensor is disposed downstream from a catalyst for purifying exhaust gas from an internal combustion engine and which can suppress an influence of unburnt hydrocarbon on an output voltage. After forming a platinum thin film on the outer periphery of a zirconia ceramic body, only a detection electrode of the ceramic body is dipped in a silver nitrate aqueous solution of 0.1 mol/l, and the silver nitrate is pyrolyzed through a heat treatment. Subsequently, a platinum reference electrode is formed on the inner periphery of the ceramic body. To protect the silver-doped detection electrode, a protective layer is formed on the surface of the detection electrode. By the exposure to combustion gas and through aging, a detection element is formed, and set into a metal case together with a cylindrical heater, to complete an oxygen sensor to be disposed downstream from a CNG engine catalyst.

Abstract: Dans un système de télévision numérique à satellite, dans lequel un téléviseur reçoit le signal via un récepteur/décodeur, tel qu'un boîtier décodeur, des application interactives peuvent être téléchargées et exécutées sur le récepteur/décodeur. Le code d'application est arrangé en modules, et le téléchargement des modules est précédé d'une recherche dans le module répertoire, à l'intérieur d'une adresse locale spécifique. Les modules sont signés et le module répertoire est signé et chiffré de telle manière qu'un seul chiffrement concerne la totalité des modules formant l'application. Des clés de chiffrement multiples publiques sont mémorisées dans la mémoire ROM du récepteur/décodeur. Ainsi les applications peuvent être créées par différentes sources, sans que ces sources aient besoin de connaître les clés de chiffrement privées des autres. Une fonction permet de mémoriser temporairement une clé de chiffrement dans la mémoire RAM du récepteur/décodeur pour permettre à un fabricant de récepteur/décodeur de vérifier son fonctionnement. Une signature du répertoire peut être cachée à une position variable à l'intérieur d'un bloc de fausses données dans le module répertoire. Une application devant être téléchargée peut être vérifiée au moyen d'une table de bits de validation d'application mémorisée dans le récepteur/décodeur.

Title: Fluid handler and method of handling a fluid
Inventor: DONAHOE THERESA M
IPC: G01F11/02
Filed: 1998-05-19
Granted: 2009-07-14
Abstract: Methods of fluid handling are disclosed. In one method, a pump fluidly associated with a nozzle is energized to move a first fluid with respect to the nozzle. Pressure fluidly associated with the nozzle is substantially continuously monitored with a pressure transducer fluidly associated with the nozzle during movement of the first fluid. An average of the pressure substantially continuously monitored is calculated. The calculated average is used to determine a threshold. The pum p fluidly associated with the nozzle is energized to move a second fluid with respect to the nozzle. Pressure fluidly associated with th e nozzle is substantially continuously monitored with a pressure transducer fluidly associated with the nozzle during movement of the second fluid. The substantially continuously monitored pressure is integrated. The threshold is compared with the integrated pressure to determine whether movement of the second fluid was intended or unintended.

Abstract: In a broadcasting satellite, signals transmitted through an up transmission line of a Ka band, which includes a plurality of communication channels, are received by a Ka-band antenna. The signals received by the antenna are passed through band-pass filters 12 to thereby extract a broadcasting signal transmitted through each communication channel. Those of the thus-extracted broadcasting signals, which have been transmitted through predetermined communication channels, are synthesized by each of synthesizers 15, then amplified by a corresponding one of high power amplifiers 16, and output to a corresponding one of a plurality of primary radiators 53 employed in an S-band antenna. The S-band antenna transmits each synthesized signal to a predetermined area that corresponds to a corresponding primary radiator 53. Thus, the system can be made to a simple structure, and the service area can be changed for each broadcasting signal.

Abstract: Self-enclosing heat exchangers are made from stacked plates having raised peripheral flanges on one side of the plates and continuous peripheral ridges on the other side of the plates, so that when the plates are put together, fully enclosed alternating flow channels are provided between the plates. The plates have raised bosses defining fluid ports that line-up in the stacked plates to form manifolds for the flow of heat exchange fluids through alternate plates.  Rib and groove barriers are formed in the plates inside the peripheral flanges and ridges. The barriers prevent short circuit flow on one side of the plates and promote flow to remote areas on the other side of the plates, to improve the overall efficiency of the heat exchangers.

Abstract: A sheet handling system for a sheet transport path of a reproduction apparatus having a sheet skew correction system being fed image substrate sheets in the process direction by a sheet transport system, wherein it is desired to positively feed and yet effectively deskew a wide range of different lengths of sheets in the process direction. A plurality of identical but independent sheet transport units may be provided spaced along the sheet transport path in the process direction engageable with a sheet being fed through sheet transport path for positively feeding even very short sheets from one sheet transport unit to another and to the skew correction system. Yet these sheet transport units provide independently automatically disengageable nips for automatically releasing even a very long sheet from any unit when that long sheet is in the skew correction system. A  different selected number of the sheet transport units are disengaged in response to a different sheet length control signal. A single stepper motor rotating a common camshaft in each unit may be used to reliably lift all the idlers of all the nips to be disengaged.

Title: Method and arrangement in a communication network
Inventor: MEE JOHN
IPC: H04M3/533
Filed: 1998-12-15
Granted: 2009-10-27
Abstract: The invention relates to a service in a communication network (100) comprising a voice messaging system (VMS1) containing a mailbox assigned to a voice mail subscriber (MS1). According to the invention, the communication network (100) transfers a voice message (105) from the calling party (TE1) to the voice messaging system (VMS1) where the message is stored in the mailbox. At some later point in time, the communication network transfers a request (106) for the status of the voice message from the calling party (TE1) to the voice messaging system (VMS1). The voice messaging system returns information (107) reflecting the status of the voice message to the calling party (TE1). In response to activities performed by the voice mail subscriber (MS1) on the voice message (105), the message status may be changed in between storage of the voice message and receipt of the status request in the voice messaging system (VMS1).

Title: Ring binder having actuating lever with cushion member
Inventor: TO CHUN YUEN
IPC: B42F13/26
Filed: 2001-01-19
Granted: 2004-12-07
Abstract: A ring binder includes a substantially rigid curved upper plate supporting a pair of hinged leaves. A plurality of ring members are secured to the hinged leaves for engaging corresponding holes in sheets of material retained by the ring binder. An actuating lever is located at each end of the curved upper plate for actuating the hinged leaves to open and close the ring members. Each actuating lever includes a tab having a cushion member formed thereon, for example by molding. The tab has an aperture therein, and cushion material enters the aperture during molding to secure the cushion member onto the tab. The cushion member is engaged by the fingers of a user to pivot the actuating lever in order to move the ring members between the open position and the closed position. The cushion member is a soft pad of material such as plastic. The cushion member provides improved tactile characteristics to the actuating lever, making the actuating lever comfortable to use. The cushion member also minimizes the feedback of undesirable shock forces produced by the snap action of the rings when opening and closing the rings.
