  • polypeptide may have a photosensitive property that changes based on at least cumulative exposure to light having a wavelength within the range between X and Y.
  • the active component and the media may be disposed in a container such as that illustrated in Fig. 2 at this time.
  • the active component and the media may then pass from the space 410 into space 412, wherein the active component and media is filled into a smaller containers, such as those illustrated in Fig. 1.
  • the filled containers may then pass into a transfer space 414 before moving to an inspection space 416 or a storage (or warehouse) space 418.
  • product may flow from the filling space 410 directly through the transfer space 414 to the inspection space 416, or may detour through the storage space 418. Additionally, before moving along the path P from the inspection space 416, the product may be returned to the warehouse space 418.
  • the product may be assembled with other items to define a system or a kit within assembly space 420. As illustrated, the product may arrive at assembly space 420 either from the inspection space 416 or the warehouse space 418.
  • the product may be combined with a syringe, such as is illustrated in Figs. 19 or 21, to define a system or to be packaged as part of a kit, in an injection kit clam shell, for example.
  • the product may be assembled as part of system in the form of a medical device, such as an autoinjector (as illustrated in Figs. 22 and 23),
  • the system or kit may pass through a loading dock 422, prior to removal from the plant 400.
  • devices 402 are disposed along the path P that the product takes through the spaces 410, 412, 414, 416, 418, 420, 422.
  • the devices 402 may include a layer of photosensitive material reactive to light having a wavelength within the range between X and Y to experience a property change (e.g., a colorimetrically detectable property change) at a threshold of cumulative exposure to light received within the range between X and Y.
  • a property change e.g., a colorimetrically detectable property change
  • the number of devices may differ between spaces, such that spaces 414, 416 have only a single device, while spaces 410, 412 have two devices, space 420 has three devices, space 422 has four devices, and space 418 has six devices.
  • the devices 402 may be attached through the use of an adhesive backing, for example, to particular structures, equipment or machinery disposed within the spaces 410-422, such as mixing tanks or syringe/cartridge filling machines for example.
  • the placement and number of devices used may be dictated by a number of factors. For example, in certain rooms, certain equipment or other environmental light sources (lamps, overhead lighting, windows, etc.) may be disposed primarily to one side of the path or the other. Additionally, it may be more desirable to place additional devices in a larger room, or a room in which the path has multiple entry and exit points, or a more complex path. For example, space 418 might qualify under all of these criteria for the inclusion of more devices 402 that in other spaces.
  • the phototrackers or photosensitive devices 402 Disposing the devices 402 along the path P permits identification and isolation of points along the path P at which light of a particular wavelength or intensity impacts the product. Through the use of the devices 402, this identification and isolation may be performed in real time.
  • the photosensitive devices 402 may be read for evidence of a property change using an optical sensing device proximate to the device 402, the optical sensing device coupled to a computing device that displays an indication of light exposure experienced by the at least one device 402.
  • a label affixed to a product may be used to determine the cumulative exposure of the individual product, and as a consequence whether the product should be used or discarded.
  • the label will not provide a history of where the product has received the exposure that has been recorded through the use of the label on the product. Even if a label attached to a product were to be inspected for cumulative light exposure at various points along the path P, using the light exposure information obtained in this fashion may still make identification and isolation of a localized spaces, areas or regions of increased light exposure or light exposure of particular wavelengths difficult. This is particular true given that certain spaces, such as space 420, may have product passing through it after having passed through any of a number of preceding spaces, because of the manner in which product may be transported between the transfer, inspection and warehouse spaces 414, 416, 418.
  • the light exposure of the product within the plant 400 may be analyzed separately from the product itself, and considered without having to account for the movement of the product along the path P.
  • readings obtained from the devices 402 disposed in the space 418 suggest that product moving along the path P are exposed to considerable amounts of light having a wavelength or wavelengths of interest relative to that product in the portion of the space where the product is stored between the inspection and assembly spaces 416, 420.
  • Additional devices 402 may then be disposed in the space 418 to further identify the source of the light, or along alternative paths within the space 418 to determine the viability of these alternative paths for the product prior to modification of the path P within the space 418. If the labels were used only on the product, the identification of such sources or alternative paths may only occur through the exposure of additional amounts of light exposure that may result in the degradation of the product and the need for its disposal.
  • Fig. 27 illustrates the range and nature of color change possible for five different sensitivities of a material that may be used in the devices 402 when exposed to varying amounts of visible light, the color change being measured according to the L*a*b index. It will also be recognized that the use of this system and method is not limited to a production facility, but might be used in other buildings or structures as well, such as a healthcare facility, testing lab, hospital or clinic.
  • the devices according to the present disclosure may have one or more advantages relative to conventional technology, any one or more of which may be present in a particular embodiment in accordance with the features of the present disclosure included in that embodiment. Other advantages not specifically listed herein may also be recognized as well.
