摘要:
A fuel reservoir having a reticulated material, generally a felt or a foam, disposed therein is provided. The addition of this reticulated material, either alone or in combination with a viscous fuel, assists the prevention of undesired flow of the fuel, the minimization of undesired leakages, and assists in orientation independence and uniform distribution of the fuel in the reservoir. The reticulated material enables the use of a viscous liquid fuel that has fuel diffusion rates and fuel utilization characteristics that approach those of neat liquid methanol. The material also helps create a greater surface area for evaporation, thus allowing a highly concentrated, vaporous fuel substance to be delivered to an associated fuel cell.

A method, a system and a computer program product for upgrading firmware is disclosed. In one embodiment data storage is managed in a data storage system comprising a first enclosure having a first storage processor and a first power supply. A firmware upgrade is saved in the first storage processor. The firmware upgrade in the first storage processor and firmware in the first power supply are compared. The firmware upgrade is downloaded to the first power supply in response to the comparison determining a difference between the firmware upgrade in the first storage processor and the firmware in the first power supply. The firmware is upgraded in the first power supply with the firmware upgrade.
摘要:
A method is used in managing loop interface instability. It is determined that a loop has excessive intermittent failures. It is determined, based on whether the intermittent failures are detectable on another loop, whether the cause of the excessive intermittent failures is within a specific category of components. A search procedure is executed that is directed to the specific category of components, to isolate the cause of the excessive intermittent failures.

A method is disclosed for determining a whether access to host requested by a user is permitted. User identifying information is obtained using any of a variety of techniques. The method includes determining a user domain, which indicates an identity of the user's home service provider. A list of hosts is determined based on the home provider. If the requested host is in the list of hosts, then the user is allowed access to the requested host though the user is not authorized. The list of hosts may be determined by one or more attributes from an actual or implied user profile, such as a domain name.

A waveguide pack for transmission of information that includes a length of a dielectric waveguide wound into a free-standing coil with an inner diameter of less than three inches and coated with a binder suited to maintaining the waveguide in the coil, and a method for preparing the pack.

A method for automatically diagnosing faults a data storage system. The system includes a plurality of enclosures each having: a primary port; an expansion port; a plurality of disk drives; and a link control card coupled to the primary port and to the expansion port and the plurality of disk drives. The link control card includes a cut through switch having: disk drive port error counters for counting at ports of the plurality of disk drives; a primary port error counter for counting cumulative errors at the primary port, and an expansion port error counter for counting cumulative errors at the expansion port. The primary ports and expansion ports are serially interconnected to the storage processor through a fiber channel loop. The method sequentially reads counters in each one of the enclosures to determine whether errors counted in any one of such counters exceeds a predetermined threshold over a predetermined period of time.

Storage stability is managed. It is detected that a disk drive is requesting to be taken offline. The disk drive is begun to be treated as being in a probation state. If within an acceptable period of time the disk drive requests to be put back online, treatment of the disk drive as being in a probation state is stopped, and only any portions of the disk drive data that were the subject of write requests involving the disk drive while the disk drive was being treated as being in a probation state are rebuilt.
摘要:
A system and method for identifying first responders at the scene of a hazardous site employs RFID technology to assemble an electronic ride list of first responders at a hazardous site. The electronic ride list is generated by polling the first responders on vehicles en route to the hazardous site. Each electronic ride list is sent to a central location, and an aggregated electronic ride list is assembled employing all of the individual electronic ride lists.
摘要:
System stability is managed. It is determined that a data storage system is responsive to an enclosure that is unstable. Based on the determination, the enclosure is temporarily prevented from being added to the data storage system.

A method is disclosed for determining whether access to a host requested by a client session connection is permitted. After determining attributes of the client session connection, a list of hosts is selected based on the determined attributes of the client session connection. The list of hosts is then used to determine whether access to the requested host is permitted. The disclosed method can be used to allow for location-specific white lists of free URLs for a user at a wireless network hotspot that the user can access before being authenticated.
