  • Publication number: 20120104815
    Abstract: The present disclosure is directed to tensioning devices and associated systems for use with child seats and other personal restraint systems. In one embodiment of the disclosure, a buckle includes a manual tensioning device configured to provide fine-tuning of harness tension when securing an occupant (e.g., a child) in a safety seat. In another embodiment, tensioning components can be configured to provide a means of dynamically adding tension in a restraint harness during crash event.

  • Patent number: 8051531
    Abstract: A cleaning appliance such as a vacuum cleaner includes a main body housing a motor and fan unit for generating a fluid flow. The main body also houses a removable pre-motor filter located upstream of the motor and fan and a removable post-motor filter located downstream of the motor and fan. It is beneficial to permit the user to be able to monitor the condition of both the pre-motor filter and the post-motor filter, and to remove and replace them as required, and so access to both filters may be provided. It is more important that the user checks the pre-motor filter as it gets dirtier than the post-motor filter. Therefore, the post-motor filter is not accessible or removable from the main body until the pre-motor filter is removed from the main body, by removing its housing.

  • Publication number: 20110025348
    Abstract: Apparatus for use in performing impedance measurements on a subject. The apparatus includes a processing system for causing a first signal to be applied to the subject, determining an indication of a second signal measured across the subject, using the indication of the second signal to determine any imbalance and if an imbalance exists, determining a modified first signal in accordance with the imbalance and causing the modified first signal to be applied to the subject to thereby allow at least one impedance measurement to be performed.

  • Publication number: 20100247933
    Abstract: Substrate such as a turbine blade provided with a coating, which consists of a material that forms a sealing oxide skin on heating. This material is a ferrous metal aluminium alloy or a ferrous metal chromium alloy, wherein the oxide skin comprises aluminium oxide or chromium oxide. In order to optimise the adhesion between the skin and the coating, it is proposed that a metal from the platinum group such as platinum or palladium be added in an amount of 0.1-0.5% (m/m). It has been found that better adhesion is obtained with this method and the detrimental effects of sodium, potassium or calcium are counteracted.

  • Patent number: 7794629
    Abstract: A composite material having a plasma frequency comprising a random mixture of conductive and non-conductive particles. A material having smaller conductive than non-conductive particles and a concentration of conductive particles approximately at, close to or above the percolation threshold for mixtures of the conducting and non-conducting particles may show a plasma frequency well below plasma frequencies for conventional bulk materials.

  • Publication number: 20100179387
    Abstract: A laryngoscope includes a blade that can be folded outwardly from a storage position to an operative position in which the blade extends from the handle at an angle of the order of 90°. Another laryngoscope includes two blade assemblies that are pivotally mounted together. Each assembly includes a blade and a removable outer sleeve or similar member that protects the blade. The assemblies can be folded outwardly from a storage position to an operative position in which the assemblies extend from each other an angle of the order of 90°. A doctor can remove the outer sleeve from a selected assembly and use the other assembly as a handle of the laryngoscope.
