Title: navigation system integrity monitoring and fault detection process
Inventor: LOIZOU JOHN DEMETRIOS
IPC: G01S1/00
Filed: 2001-10-08
Abstract: An integrity monitoring and fault detection process for navigation systems (eg GPS) which includes a weighted Total Least Squares (TLS) analysis of an over-determined positioning problem, used to generate a test statistic indicating the self consistency of the linear model used in the TLS analysis. In addition, for a given over-determined positioning problem a fault detection threshold is determined for the test statistic, as a function of a specified probability of false alarm. Furthermore, appropriate weightings may be determined to be used in Total Least Squares solutions of over-determined positioning problems, such that emphasis can be given to the required dimensions to be protected, such as Vertical Protection Limits. Also, for a given over-determined positioning problem, a limit on position errors such as a Vertical Protection Limit can be determined, as a function of specified false alarm and missed detection probabilities.

Abstract: A turbocharged internal combustion engine comprises an air inlet; an exhaust gas outlet; a turbocharger having a turbine gas inlet, a variable turbine, a compressor and a gas outlet from the compressor; and further comprising a bypass valve interposed between the engine exhaust gas outlet and the turbine inlet. This engine is preferably operated by reducing the effective area of the variable turbine while the bypass valve is kept closed, monitoring the outlet air pressure from the compressor or the turbocharger speed, detecting when one of these parameters reaches a predetermined value and then opening the bypass valve while keeping the variable turbine in the closed position until the predetermined values are re-achieved.

Title: A plastic blow-moulding process
Inventor: MADDEN SEAMUS OLIVER
IPC: B29C49/18
Filed: 2004-03-29
Abstract: A process for manufacturing thin walled plastics containers e.g. bottles with a neck portion comprises a mould 10 wherein a parison (90 figure 6a) of plastics material is extruded about a blow pin (51 figure 4) between a pair of spaced apart mould halves (48, 49 figure 5). As the mould halves close, low pressure pre-blow air is delivered through the blow pin for partially inflating the parison in the mould. Upon closure of the mould high pressure air is delivered through the blow pin to rapidly inflate the parison against the inner wall of the mould to form the bottle. Whilst the plastics material is still malleable at the neck of the bottle the blow pin is advanced into the mould to gather and compress plastics material at the neck of the bottle which is then cut by a cutting ring (58 figure 4) on the blow pin. Upon opening the mould the bottle is removed and delivered by a conveyor 12 and a feeder 15 to a deflashing station 16 at which excess waste plastics material is removed. The bottles are then delivered by conveyors 18, 30 to a packaging station 32.

Title: Tetrahedral amorphous carbon coating with pre-determined resistivity
Inventor: SHI XU
IPC: H01L33/26
Filed: 2004-08-27
Abstract: A method and apparatus for providing a substrate coating having a predetermined resistivity. The method comprises the steps of providing a substrate 24a to be coated in a vacuum chamber 11, creating a carbon plasma in the chamber, and depositing ions of the plasma on the substrate to form a ta-C substrate coating. The coating step is stopped when the ta-C substrate coating has the predetermined resistivity. The predetermined resistivity is 10<5>-10<10>  L  cm, and preferably about 10<6>  L  cm. The substrate may be biased during the method to aid in arriving at the predetermined resistivity. The coating may be employed to reduce the risk of, or prevent electrostatic discharge to or from the substrate, or to provide a seed layer to improve adhesion between the substrate a further coating. Also described are coatings having predetermined resistivities, and an organic light emitting diode (OLED) incorporating a ta-C layer.
Patent GB-2408627-A (GB)
Title: Optical medium recognition
Inventor: ERICKSON DIRK
IPC: G11B7/125
Filed: 2004-11-25
Abstract: An optical medium associated with a first type of optical drive laser, such as a blue laser, embeds identification information readable by a second type of optical drive laser, such as a red laser associated with DVD media or an IR laser associated with CD media, in order to reduce the time used by the optical drive to recognize media. An attempt to read the embedded identification information by the second laser that succeeds provides the optical drive with the information to proceed with use of the optical medium using the first laser. An attempt to read the embedded identification information that fails provides the optical drive with the opportunity to detect whether the optical medium is associated with the second laser so that a single spindle kick of the optical medium by the optical drive determines whether the optical medium is associated with either of two types of lasers.
