An apparatus and a method for detecting leakage from a composition-containing pouch during the high-speed manufacturing process. The apparatus comprises: a platen comprising a pouch cavity and a plurality of platen edges adjacent to the cavity; an image capturing unit; an image processing unit; and ultraviolet-light emitting source. The composition itself comprises a fluorescent whitening compound. The ultra-violet emitting light source is arranged to illuminate the cavity and plurality of platen edges. The image capturing unit is arranged to capture an image of the illuminated cavity and plurality of platen edges. The image capturing unit is communicably attached to the image processing unit.

A method for ascertaining the presence of cracks in sealed containers includes steps of defining a detection zone (13) in which a sealed container (CT) will be placed, placing a container (CT) in the detection zone (13), ascertaining the presence of a thermal gradient determined by the container in the detection zone (13), the thermal gradient being indicative of the presence of a crack in the container (CT).

A leak detection system for detecting breaches in sealed food containers is disclosed. The leak detection system comprises a first optical sensor configured to transmit a light signal across a first testing path, said first optical sensor being sensitive to gas composition variations. A permeable pressing member is configured to, in use, apply pressure to the sealed food container. The first optical sensor is arranged such that at least a portion of the first testing path along which the light signal is transmitted is located behind or within the permeable pressing member.

A system and method is for determining a concentration of at least one gas in a container having at least one side with a flexible area. The system includes a measuring area arranged for receiving the container; a suction device arranged for pulling at least one portion of the flexible area a distance to arranging at least the portion of the flexible area in a position to provide a space underneath at least the portion of the flexible area; an optical sensor, configured to be sensitive to the at least one gas, is arranged in relation to the measuring area for transmitting a light signal through the space and detecting a transmitted light signal; and a controller configured for determining, based on the transmitted light signal, the concentration of the at least one gas in the container.

A pneumatic smoke injection device for identifying an air leak in a tire includes a housing that has an air inlet which can be coupled to a supply hose of source of compressed air. An air hose is coupled to and extends away from the housing. The air hose has an air coupler that can be attached to a valve stem of a vehicle tire to direct to compressed air into the vehicle tire when the air coupler is attached to the valve stem. A smoke unit is integrated into the housing and the smoke unit produces a brightly colored smoke when the smoke unit is turned on. The smoke unit releases the brightly colored smoke into the air hose thereby facilitating an air leak in the vehicle tire be visually identified by the brightly colored smoke flowing outwardly from the air leak.

Methods and manufactures disclosed herein generally relate to a cannular composite (ITC) structure composed of multiple layers of sealing, reinforcement, sensing, protection, and interspatial injected materials.

A system and method are for determining a concentration of at least one gas in a container having at least one side with a flexible area. The system includes a measuring area arranged for receiving the container; a suction device arranged for pulling at least one portion of the flexible area a distance to arranging at least the portion of the flexible area in a position to provide a space underneath at least the portion of the flexible area; an optical sensor, configured to be sensitive to the at least one gas, is arranged in relation to the measuring area for transmitting a light signal through the space and detecting a transmitted light signal; and a control unit configured for determining, based on the transmitted light signal, the concentration of the at least one gas in the container.

Disclosed is a method of integrity testing of a single-use system for processing a fluidic material. In the inventive method, a single-use system for processing at least one fluidic material is provided. The single-use system has at least one plastic component. A test gas is applied to a lumen of the single-use system. The test gas has one or more of spectral absorption or spectral emission properties in the infrared spectral range distinguishable from ambient air. At least a part of the single-use system is monitored using an infrared camera. A method of processing a fluidic material by using a single-use system and a test system for integrity testing of a single-use system are also disclosed.
