Title: Apparatus for demodulating and decoding satellite, terrestrial, and cable transmitted digital television data
Inventor: STEWART JOHN SIDNEY
IPC: H03M13/23
Filed: 1995-10-26
Granted: 2001-05-22
Abstract: A Digital signal processor selectively demodulates and decodes signals received from multiple types of transmission channels such as satellite, terrestrial and cable transmission channels. A received signal is representative of compressed digital video information such as television picture information, and is encoded in one of a plurality of coding formats (e.g., trellis or punctured codes of selectable code rate). The received signal is also modulated in one of a plurality of modulation formats (e.g., PAM, QAM or PSK). A demodulator selectively demodulates the signal modulated in one of the plurality of modulation formats, and a decoder selectively decodes the demodulated signal coded in one of the plurality of coding formats.

Abstract: A connector having at least three parts is used to connect a fluid line to an opening of a component that is made of a thermoplastic material. The connector is produced by forming a first part of the connector from an essentially thermoplastic material. A  second part and a third part of the connector are produced from an essentially thermoplastic material so that the second part and the third part are fused together. The first part and the second part are connected in a fluid-tight manner outside of a mold. The material of the third part is selected so that it is capable of forming a fusion connection with the thermoplastic material of the component. The connector can also have at least one part. This connector is produced by injection molding a first outer part, an inner layer and an intermediate layer. The materials of the first outer part and the inner layer and the material of the intermediate layer are selected so that they have different properties with respect to their strength, impact resistance, and tendency to creep. At least one of the first outer part, the inner layer and the intermediate layer is formed so as to be impervious to diffusion.

Abstract: La présente invention concerne un procédé qui permet de contrôler la présentation d'annonces publicitaires associées à des réseaux, chaînes ou programmes de télévision, et de passer chaque annonce associée à un réseau sur de nombreux systèmes de télévision en parallèle. Pour contrôler la présentation des annonces, on détermine, au niveau de l'équipement de télévision du téléspectateur, si les réseaux, chaînes ou programmes de télévision associés sont indisponibles ou indésirables pour le téléspectateur. L'équipement de télévision du téléspectateur présente ensuite les annonces publicitaires ou choisit de présenter des annonces de remplacement appropriées. Une seule diffusion de chaque annonce de réseau est autorisée et chaque annonce est diffusée avec un identificateur de tous les systèmes de télévision. On détermine ensuite si une station locale de ce réseau est disponible et si elle n'est pas jugée indésirable pour le téléspectateur. Sur la base de cette détermination, l'annonce publicitaire ou une annonce de remplacement appropriée est présentée au téléspectateur.

Title: Wireless home fire and security alarm system
Inventor: LIU KAI BANG
IPC: G08B17/00
Filed: 1999-10-06
Granted: 2009-01-20
Abstract: A wireless alarm system (10) employs two-way transceivers (32, 60) in a network of smoke detectors (16), a base station (12), and other sensors. A keypad (14) is not needed because the system is reset by pressing a Test/Silence button (66) built into every detector or sensor. A siren is also eliminated because a sounder (64) in every detector sounds an alarm when any sensor is triggered. This is possible because every detector includes a transceiver that can receive alarm messages from any other detector. AC power wiring is also eliminated because the base station and sensors are battery powered. Only a telephone connection (48) is needed if the system is to be monitored.  In apartments or dormitory installations, smoke detectors in one apartment relay alarm messages to the next apartment, and onto the next, and so on, to a centralized base station for the entire facility. The centralized base station can be located in an apartment manager's office for immediate notification of an alarm, improper smoke detector operation, low or missing battery indications, and dirty smoke detector indications. The two-way wireless alarm system can save many lives in apartments, where smoke detectors batteries are often depleted or removed.
