  • Patent number: 11920198
    Abstract: This invention relates to a method of identifying mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, a kit for performing the method, and furthermore to isolated nucleotide sequences being complementary to one or more mutations of the CFTR gene. According to a first aspect of the invention there is provided a method of identifying mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, including the steps of providing one or more nucleic acid sequences, fully complementary to one or more segments of the CFTR gene, wherein the one or more nucleic acid sequences correspond to the mutation to be identified; providing a biological sample of an individual to be tested for CF; isolating nucleic acids from the biological sample; and testing the biological sample for the presence of one or more of the nucleic acid sequences using a suitable detection method.

  • Patent number: 8049612
    Abstract: A hazard detector monitoring system comprises one or more smoke detectors each provided with an electronic device containing information unique to the detector so as to identify the detector. A testing device is located at the end of a pole and held adjacent the detector to read and write to the electronic device through a wireless communication link. The testing device causes the detector to carry out a predetermined operation and the result of the operation is read by the testing device from the electronic device using the wireless communication link together with the identity of the detector.

  • Patent number: 7852227
    Abstract: The present invention relates to an electrically operated device for generating synthetic smoke and also to a hazard detector tester utilizing such a device. The device comprises a collapsible container provided with vaporisable liquid and a tube, one end of which is immersed in the liquid and the other end of which is provided with an electrical heater for vaporising the liquid in the other end of the tub in order to generate smoke. A peristaltic pump is used to pump the liquid through the tube.

  • Patent number: 6640608
    Abstract: An apparatus for testing a smoking or fire detector includes an open-topped housing for receiving a detector under test. A stream of fluid for activating the detector is generated in a portion of the housing below the detector and is directed by a duct up one side of the interior of the housing to flow across the housing in a direction of the detector. A spacer can be provided in order to ensure that the direction of flow is precisely located at a point that is a predetermined distance above the bottom of the detector. Also, a heating element may be provided in the duct if required.
