IPC: H04N5/00
Filed: 2000-08-09
Abstract: A Hard Disk Recorder (HDR)(3) is arranged to receive signals signals defining television programmes and television programme schedule data. The HDR    receives updated programme schedule data substantially constantly in a dedicated programme schedule data channel. The HDR is arranged to output the programme schedule data for display on a television screen (2). The HDR comprises a hard disk (16) for recording received television programmes. A remote control (28) is provided to select television programmes to be recorded from the displayed programme schedule. Furthermore, the HDR is arranged to receive additional programme schedule information included in each of the received television channels which information is used to control the hard disk to record pre-programmed television programmes according to schedule. The hard disk is operable to record simultaneously two different television programmes received in different channels.  Also, the HDR is operable to replay a currently broadcast programme offset in time.  The time offset can be overcome by playing back the part of the programme inside the time offset at an increased frame rate. Furthermore, the HDR is arranged to receive transition signals indicating transitions between parts of programmes, such as transitions between advertisements and the "actual" programmes. The HDR is operable to use these transition signals, for example, to skip between transitions in previously recorded programmes replayed from the hard disk.

Filed: 2000-08-22
Abstract: A method and apparatus is provided for the vaporization of liquid hydrocarbon fuel in a closed system prior to its entry into an internal combustion engine's combustion chambers in amounts proportional to the acceleration level of the engine. The apparatus is a fuel vaporizer (10) interposed between an engine's fuel injection system and combustion chambers and forms a canister housing. Liquid fuel enters via an inlet (16) in the housing, is vaporized by heating it to boiling and is drawn out of the canister via an outlet (26) under a partial vacuum to the combustion chambers of the engine.  The system is closed except for a vacuum connection with the engine's combustion chambers. Heating means (12) are provided to heat the fuel to boiling without heating it to its flash point, thus avoiding its pre-ignition.
