摘要:
A composition, method, and system for recording an image. The system includes a multiphase imaging material in which energy is absorbed by an antenna material. The absorbed energy causes the reaction of an activator and a color-forming material to form a mark. A fixer is employed to retard the fading of the mark.

摘要:
Compositions and methods for production of color images which are developable with improved marking sensitivity and image contrast are disclosed and described. Specifically, a color forming composition can comprise a polymeric activator phase including a polymer matrix and an activator dissolved therein, a color former phase including a color former, and a radiation absorber in thermal contact with the color former phase. Particularly, the color former phase can be finely dispersed within the polymeric activator phase at an average particle size of less than 2 μm.

Compositions and methods for production of color images which are developable at sub-infrared wavelengths are disclosed and described. The color forming composition can include a polymer matrix having a color former phase adjacent to or dispersed within the polymer matrix. The color former phase can include a color former and an optional melting aid. Further, a radiation absorber can be admixed with or in thermal contact with the color former phase. The color forming composition can also be optimized for development using electromagnetic radiation having a development wavelength from about 300 nm to about 500 nm. The color forming compositions are useful in forming images on a wide variety of substrates such as optical disks.

A data storage device includes a surface used for labeling. The surface is covered, at least in part, with a laser imageable coating. Blocking material is placed over a portion of the laser imageable coating. The blocking material blocks laser imaging on the portion of the laser imageable coating over which the blocking material is placed.
摘要:
A protective container for containing a material and protecting against adverse exposure to the material, which is particularly adapted for use with fuel cells, can include a durable outer casing and an inner casing. The inner casing is less durable than the outer casing. At least one layer of a preventative agent is disposed between the inner and outer casings that is configured to disable at least a portion of the material upon failure of the inner casing.
摘要:
Representative embodiments provide for a fuel activation device including a fuel storage chamber configured to store a plurality of fuel pellets arranged as a stack. A fuel dispensing device is configured to transport a fuel pellet to a fuel activation chamber. A spring is configured to advance the fuel pellets toward the fuel dispensing device as one or more fuel pellets are removed from the stack. A fuel initiator is configured to activate a release of hydrogen gas from the transported fuel pellet. The fuel activation device is configured to provide the hydrogen gas to a fuel cell through a gas vent. A method is provided including providing a plurality of fuel pellets arranged as a spring-loaded stack, transporting a fuel pellet from the stack, activating a release of hydrogen gas from the transported fuel pellet, and providing the hydrogen gas to a fuel cell.
