A respirator fit-check apparatus has an air pressure sensor adapted, in use, to sense the air pressure within a sealed interior volume of a close-fitting respirator; an indicator adapted, in use, to indicate instructions and test results to a wearer of the respirator; and a CPU, the apparatus being configured to monitor the air pressure within the respirator and to determine and indicate whether or not the respirator seals to the face of a wearer based on a vacuum decay over a specified period of time. The apparatus may also be configured to monitor the breathing depth and/or rate of the wearer subsequent to a fit-check determination.

A method for in-line leak testing of blow moulded containers wherein a conveyor line is fed with a continuous stream of blow moulded containers from a blow moulding machine, at least one measuring head is temporarily connected to a first blow moulded container. The measuring head is moved in order to follow the movement of said first blow moulded container which is pressurized by a source of pressurized gas, the source of pressurized gas is disconnected, said at least one measuring head is used to measure the pressure decay therein. The pressure decay is compared with stored data for the pressure decay of acceptable containers and an accept or non-accept signal is generated which implies proceeding or disposal of said first blow moulded container. The measuring head is moved against the moving direction of the conveyor line to a subsequent blow moulded container, and the process is repeated.

Wearable protection device (1) comprising at least one inflatable bag (8) configured to assume alternately a rest configuration, wherein it is in a deflated state, and an active configuration, wherein it is in an inflated state and inflation means (14) in fluid communication with the inflatable bag (8) and configured to introduce therein an inflation fluid once they have been triggered. The wearable protection device (1) further comprises at least one pressure detecting device (26) associated with the at least one inflatable bag and configured for directly or indirectly detecting the pressure inside the at least one inflatable bag (8). A further object of the present invention is a method for evaluating if an inflatable bag (8) of a wearable protection device (1) is reusable once it has been inflated.

A power electronics unit for an aircraft and a method of determining the integrity of a power electronics unit are provided. The power electronics unit comprises an electric machine controller; a heatsink arranged to conduct heat from the electric machine controller; a housing comprising a sealed internal volume enclosing the electric machine controller and heatsink; a dielectric liquid partially filling the internal volume to cover the electric machine controller; a gas pocket within the internal volume; a pressure sensor arranged to measure a pressure of gas within the gas pocket; a temperature sensor arranged to measure a temperature within the internal volume; and a controller. The controller is configured to receive signals from the pressure sensor and temperature sensor, determine a pressure and temperature from the received signals and provide an output signal dependent on the determined temperature and pressure.

A system for transporting and evaluating flexible bags filled with product includes a running rail and a plurality of conveying elements mounted for movement along the running rail. A control system is configured such that each conveying element is independently movable along running rail, wherein the control system is further configured such that a first conveying element of the plurality of conveying elements and a second conveying element of the plurality of conveying elements are controlled such that a flexible bag is squeezed between the first conveying element and the second conveying element, and the control system is further configured to evaluate a squeeze force on the flexible bag and/or a dimensional spacing between the first conveying element and the second conveying element in order to identify the flexible bag as having a satisfactory seal or an unsatisfactory seal.

A dispenser head (100) for dispensing a unit (C) of a pharmaceutical drug or a food supplement or food is provided, said dispenser head (100) comprising: a dosing duct (102) extending along a dosing axis (104) and connecting an inlet port (106) for receiving the unit (C) from a reservoir (11) with an outlet port (108) for dispensing the unit (C); a support section (130) for the unit (C), which extends from the exit port (108) parallel to the dosing axis (104); and a retention section (110), which extends from the support section (130).

A gas detection apparatus for cell module assemblies accurately and rapidly detects a damaged cell of a cell module assembly and the damaged position of the damaged cell. The gas detection apparatus includes a gas detection chamber configured to receive a cell module assembly; and a sliding die configured to be movable to the lower part of the gas detection chamber in the state in which the cell module assembly is disposed at the upper end thereof. The gas detection apparatus further includes a gas sensor provided in the gas detection chamber, the gas sensor including a plurality of gas sensors disposed so as to correspond to positions of cells of the cell module assembly. A gas detection method for cell module assemblies uses the gas detection apparatus for cell module assemblies.

A biocontainer having a first film, the film having an interior and exterior side; articulating elements disposed on or within the first film, the articulating elements comprising at least one a folded hinge, a sealed joint, a thinned pathway, a bowed path, an embedded polymeric or metallic cylindrical fiber or rod; and a second film, optionally comprising articulating elements, joined to the first film, to form a biocontainer having a closed volume, wherein the articulating elements permit the biocontainer to expand and collapse along the articulating elements.

An apparatus for detecting a puncture comprises a housing comprising a plurality of compartments. Each compartment comprises an opening for receiving a flow of air into the compartment. Each compartment also comprises a detection element mounted on an axle, the axle having a first end and a second end and being secured at said first end and said second end within the compartment. The detection element is rotatable about the axle and when a flow of air passes through the opening into the compartment, the detection element rotates around the axle in response to the flow of air.

A delaminatable container is provided that includes a valve member allowing suppression of interference with the motion of a mobile part during use. The present invention provides a delaminatable container including an outer shell and an inner bag, the inner bag to be shrunk with a decrease in contents, wherein the outer shell includes a fresh air inlet communicating an external space with an intermediate space between the outer shell and the inner bag, the fresh air inlet has a valve member mounted thereto to regulate air communication between the intermediate space and the external space, the valve member includes a tube having a cavity provided to communicate the external space with the intermediate space and a mobile part movably stored in the cavity.
