Abstract: A method of making a cathode for a battery includes the steps of depositing a precursor cathode film having a first crystallinity profile. The precursor cathode film is annealed by irradiating the precursor cathode film with from 1 to 100 photonic pulses having a wavelength of from 200 nm to 1600 nm, a pulse duration of from 0.01 ?s and 5000 ?s and a pulse frequency of from 1 nHz to 100 Hz. The photonic pulses are continued until the precursor cathode film has recrystallized from the first crystallinity profile to a second crystallinity profile.

Abstract: The invention provides a method of making a battery anode in which a quantity of graphite powder is provided. The temperature of the graphite powder is raised from a starting temperature to a first temperature between 1000 and 2000° C. during a first heating period. The graphite powder is then cooled to a final temperature during a cool down period. The graphite powder is contacted with a forming gas during at least one of the first heating period and the cool down period. The forming gas includes H2 and an inert gas.

Abstract: A secure data broker has been developed, which provides a restricted message based data exchange between a client application and a secured information resource by allowing registered or verified messages to be brokered across a security barrier. In some configurations, both requests and responses are validated and brokered across the security barrier. In other configuration, either requests or responses are validated. To support validation, messages are formatted in accordance with a predefined message specification for at least part of a transaction path between a client application and an information resource accessed by the client application.

Abstract: A security architecture has been developed in which a single sign-on is provided for multiple information resources. Rather than specifying a single authentication scheme for all information resources, the security architecture associates trust-level requirements with information resources. Authentication schemes (e.g., those based on passwords, certificates, biometric techniques, smart cards, etc.) are employed depending on the trust-level requirement(s) of an information resource (or information resources) to be accessed. Once credentials have been obtained for an entity and the entity has been authenticated to a given trust level, access is granted, without the need for further credentials and authentication, to information resources for which the authenticated trust level is sufficient.

Abstract: A fuel cell system with a proton exchange membrane. There is a cathode catalyst layer overlying the first face of the proton exchange membrane, and a cathode diffusion layer overlying the cathode catalyst layer. There is an anode catalyst layer overlying the second face of the proton exchange membrane, and an anode diffusion layer overlying the anode catalyst layer. The cathode diffusion layer has a water vapor permeance of less than about 3×10?4 g/(Pa s m2) at 80° C. and 1 atmosphere. The invention also relates to cathode diffusion layers for fuel cell systems.

In addition, an entity can be allocated a new session and associated default credential if the entity's access request indicates an invalid session token or does not indicate a token.

Rather than specifying a single authentication scheme for all information resources, the security architecture associates trust-level requirements with information resources. Authentication schemes (e.g., those based on passwords, certificates, biometric techniques, smart cards, etc.) are associated with trust levels and a log-on service obtains credentials for an entity commensurate with the trust-level requirement(s) of an information resource (or information resources) to be accessed. Once credentials have been obtained for an entity and the entity has been authenticated to a given trust level, access is granted, without the need for further credentials and authentication, to information resources for which the authenticated trust level is sufficient.

Abstract: By including environment information in a security policy, a security architecture advantageously allows temporal, locational, connection type and/or client capabilities-related information to affect the sufficiency of a given credential type (and associated authentication scheme) for access to a particular information resource. In some configurations, time of access, originating location (physical or network) and/or connection type form a risk profile that can be factored into credential type sufficiency. In some configurations, changing environmental parameters may cause a previously sufficient credential to become insufficient. Alternatively, an authenticated credential previously insufficient for access at a given trust level may be sufficient based on a changed or more fully parameterized session environment. In some configurations, the use of session tracking facilites (e.g., the information content of session tokens) can be tailored to environmental parameters (e.g., connection type or location).

Abstract: A security architecture has been developed in which a single sign-on is provided. Session credentials are used to maintain continuity of a persistent session across multiple accesses to one or more information resources, and in some embodiments, across credential level changes. Session credentials are secured, e.g., as a cryptographically secured session token, such that they may be inspected by a wide variety of entities or applications to verify an authenticated trust level, yet may not be prepared or altered except by a trusted authentication service. Some embodiments of the present invention associate trust level requirements with information resources. Authentication schemes (e.g., those based on passwords, certificates, biometric techniques, smart cards, etc.) are associated with trust levels, and in some embodiments, with environmental parameters.

Abstract: Provided are termite phagostimulatory compositions extracted from fungi coexisting with subterranean termites. In a preferred embodiment, a subterranean termite feeding stimulant is obtained from extracts of fungi coexisting with Reticulitermes hesperus. Termite feeding stimulants in accordance with the present invention may be incorporated into termiticide-treated bait-based systems and methods to selectively target and enhance control of subterranean termites. Also provided are compositions which deter feeding of subterranean termites. These phagodeterrent compositions may be obtained from non-polar extracts of subterranean termite-associated fungus-colonized filter paper. They may also find useful application in termite control strategies, for example, by deterring subterranean termites from colonizing or feeding on particular substrates and structures.

Abstract: A multi-layer industrial type woven webbing having a multiple weave construction has at least one warp end of polyamid yarn adjacent both of the selvage edges of both the upper layer of fabric and the lower layer of fabric to provide greater toughness at the edges of the webbing. Further toughness of the edges is provided by additionally adding two or more warp ends of polyamid monofilament at each selvage edge of each fabric layer.
