  • Patent number: 11602948
    Abstract: Techniques are described in which articles (e.g., security documents, traffic signage and personal protective equipment) are formed to include an infrared absorptive material. In some instances, the infrared absorptive material includes a reduced tungsten oxide, such as cesium tungsten oxide, calcium tungsten oxide, potassium tungsten oxide, or the like, and exposed to radiation such that one or more regions of the security document has a modified appearance, thereby providing a visual marking or information on the article. Example articles include at least one layer including a polymer and an infrared absorptive material including a reduced tungsten oxide. The layer includes a radiation-treated region that exhibits a first appearance under visible light and at least one non-radiation-treated region that exhibits a second, different appearance under visible light.

  • Patent number: 7502757
    Abstract: In accordance with the present invention, a system and method for matching buyers and sellers in a marketplace accepts limit bids and offers into a central system. Periodically, an optimizing algorithm is executed to match buyers and sellers. The algorithm utilizes techniques to maximize global utility. After buyers and sellers are matched, a transaction price is calculated for each pairing. The transaction price is selected to ensure that each participant executes the transaction at that participant's best effective transaction price.

  • Publication number: 20080021511
    Abstract: An implantable medical device (IMD) including a nonhermetic battery is described. The IMD includes components and a power source module that includes the nonhermetic battery. The IMD also includes a barrier to substantially impede movement of substances from the nonhermetic battery to the components. The barrier may include a hermetic feedthrough, a gel, a polymer, or a solid electrolyte within the nonhermetic battery, and a seal member. The barrier may also be a material that encapsulates the nonhermetic battery and a getter within the IMD. In some embodiments, the IMD comprises a modular IMD including an interconnect member. In that case, the barrier may include a material that fills at least a portion of a void defined by the interconnect member. A length and a cross-sectional area of the interconnect member may also act as a barrier.
