Abstract: A monolithic semiconductor photo-coupler device comprises a substrate made of semiconductor material, and a groove made in one face of the substrate to receive and align an optical fiber. A wall of given thickness is formed in the semiconductor material of the substrate in the prolongation of the groove and transversally to this groove. The wall has, on the side of the groove, a first face generally perpendicular to the groove, and a second face opposite to the first face. The semiconductor material preferably comprises silicon whereby p-doped and n-doped regions can be produced on the first and second faces of the wall, respectively. These p- and n-doped regions are separated by an intrinsic semiconductor region. Finally, first and second electrodes are applied to the substrate in contact with the p- and n-doped regions. The p-doped region, the intrinsic semiconductor region and the n-doped region form a p-i-n photodetector capable of converting an optical signal from an optical fiber placed in the groove to an electric signal. When placed in the groove, the optical fiber is in direct alignment with the photodetector. The present invention is also concerned with a method for fabricating the above described monolithic semiconductor photo-coupler device.

Abstract: A generally circular flat housing (10) supports a handle (12), a pivotable lever (21), and a base portion (13). At the circular portion of the housing, a ring of character segments (31) each having a visually depicted character (41) thereon are supported. A pointer (60) is rotatably supportable upon the housing and is movable to point to a selected one of the characters. A character image (63) is supported on a circular plate (62) at the center of the housing and includes apparatus for moving face components (64, 66) to simulate the speaking action of the image character. An electronic sound module of conventional design is supported within the interior of the housing and is provided with speech or phrase selections by a rotating multiple segment contact pad set together with a pair of contact brushes. When the pivotally mounted handle is pulled down, a gear drive mechanism is configured for operation and energy is stored in a return spring.  When the handle is released, the energy within the stored spring draws the handle upwardly in a slow travel which further drives the gear mechanism for animating the character face and which triggers the production of sound from the sound module.

Abstract: La présente invention concerne un procédé de rinçage sanitaire d'un animal sur une chaîne de production comptant une pluralité d'étriers. Chaque étrier est muni d'une étiquette d'identification par fréquence radio (RFID) portant un numéro d'étrier spécifique lisible par machine. Une fois assommé et fixé à l'étrier, l'animal est acheminé jusqu'à un poste de pesée équipée d'un lecteur d'étiquette RFID qui pèse l'animal et en communique le poids ainsi que le numéro d'étrier à un ordinateur pour enregistrement dans une base de données. L'animal est ensuite saigné et transporté jusqu'à un poste de rinçage équipée d'un lecteur d'étiquette RFID qui lit le numéro d'identification. Après consultation du poids de l'animal qui doit être rincé sur ce poste particulier de rinçage, le système calcule la dose de solution à injecter dans l'appareil circulatoire de l'animal. Après désinfection du flexible et de son injecteur et des mains de l'opérateur, l'injecteur est introduit dans un point d'entrée de l'appareil circulatoire de l'animal et l'opérateur entreprend d'injecter la dose prédéterminée de solution dans l'animal. Si le rinçage n'est pas effectué dans un laps de temps déterminé, l'opérateur doit procéder à une nouvelle désinfection.

Abstract: A control system for a utility vehicle, particularly a compact utility tractor, that is speed-controlled by a hydrostatic transmission, prevents engine stalling by automatically reducing the stroke of a pump of the hydrostatic transmission, and thus reducing the vehicle speed, when the unloaded engine speed drops below a predetermined threshold. The apparatus includes a servo controlled hydrostatic transmission, an engine speed sensor, a throttle position sensor and a controller. The unloaded engine speed is determined by either an engine throttle lever position or by an engine speed capture algorithm that continuously monitors engine speed and records engine speed occurring when the transmission control pedals are positioned in neutral.

Abstract: L'invention concerne un terminal de transmission transmettant des signaux sous forme de paquets à un terminal de réception. Si le paquet est destiné au terminal de réception, celui-ci démodule le paquet. Le terminal de réception calcule alors une mesure de qualité du paquet et compare la mesure de qualité calculée avec une mesure de qualité contenue dans le paquet. Si les mesures de qualité correspondent, le paquet est retransmis pour un autre traitement. Si les mesures de qualité ne correspondent pas, le terminal de réception envoie une demande de retransmission du paquet. Le terminal de transmission détermine quel paquet doit être retransmis suite à la demande de retransmission. Si la livraison du paquet selon le système mentionné ci-dessus échoue, on procède alors à une tentative de retransmission selon des systèmes conventionnels basés sur des numéros de séquence, par exemple un protocole de liaison radio.

Abstract: A system and method for remotely triggering a predetermined program at a host computer system using a telephone ring signal is disclosed. The host computer system includes a ring detection and triggering circuit, a control monitor program, and at least one activation script, wherein the activation script could be a series of commands which create a connection between the host system and the Internet. A ring signal on a phone line connected to the host system is detected by the ring detection circuitry, and subsequently a trigger signal is generated by a trigger circuit which is detected by the control monitor program running on the host system. The control monitor program responds to the trigger signal and executes the activation script, thereby causing a connection to be established between the host system and the Internet. Other features, such as multiple activation scripts, remote user authentication, and feedback validation tones are also disclosed.      Further disclosed is a method of operating an ISP server computer for detecting whether a connection is being requested of a customer's host computer system, of determining whether the host computer system is presently connected to the Internet, and if the host system is not connected, of dialing a phone number which triggers an activation program stored at the host system, thereby causing the host system to connect to the Internet so that it can be accessed.

Title: Method and apparatus for targeting virtual objects
Inventor: HENDRICKS JOHN S
IPC: H04N7/173
Filed: 2001-06-19
Granted: 2011-02-08
Abstract: A method and an apparatus are used to target virtual objects to subscribers in a television delivery system. Programs are selected and virtual object locations are defined in the selected programs. The virtual objects available for targeting are categorized and the categories are correlated to subscriber information to determine the optimum targeting of the virtual objects. The virtual objects may be targeted based on individual subscriber information or on information related to groups of subscribers. When a frame of a program includes a virtual object location, a default or an alternate virtual object is displayed. The virtual object location may change over space or time. The virtual object may be interactive, and may be used to link a subscriber to a remote location, such as an Internet web site. An operations center or a cable headend may generate a group assignment plan that assigns the subscribers' television terminals to groups, based on factors such as area of dominant influence and household income. A retrieval plan is then generated that instructs the television terminals to select the desired virtual object for display. The television terminals record which virtual objects were displayed, and report this information to the cable headends and the operations center.  The reported information is used to generate billing for commercial advertisers, and to analyze viewer watching habits. The invention uses upstream data reception hardware, databases and processing hardware and software, and corresponding features in the televisions to accomplish these functions.
