摘要： The corrosion resistance of an aluminum or aluminum alloy component is enhanced by immersing an aluminum alloy to act as a cathode and an oxygen-evolving anode in an electrolyte comprising water, cerium ions, and an additive selected from among animal gelatin, derivatives of animal gelatin, and amino acids, then passing an electrical current through the electrolyte to deposit a cerium-based coating onto the aluminum-based component.

摘要： A cerium-based coating for corrosion resistance is applied by exposing a cleaned aluminum-based component to a corrosion-inhibiting cerium solution containing cerium ions in the presence of an oxidizing agent. The coating deposits spontaneously without an external source of electrons.

摘要： A flexible dust cover is provided for use with a parallel optical communications module for preventing airborne matter, such as dirt, dust, and gases from entering the module. The flexible dust cover fits snugly to the module to protect components of the module and the optical pathways of the module from airborne matter. The flexible dust cover has an elasticity that allows it to be temporarily deformed from its original shape to a stretched state by application of a stretching force to enable the module to be inserted into a central opening formed in the cover. The force is then removed, causing the cover to attempt to return to its original, non-stretched shape. When this happens, interior surfaces of the cover form a snug fit about exterior surfaces of the module. This snug fit fills in air gaps in the module that would otherwise be exposed to the environment.

摘要： An optical transceiver module is provided with an elongated delatching pull tab that that enables an optical transceiver module to be easily delatched and pulled from a cage without having to first unplug optical fiber cables from the module and without having to rotate a bail. Thus, the number of manual actions that need to be performed by a user to remove the module from a cage is drastically reduced, which makes simplifies the removal process and makes the design well suited for use in hot-pluggable environments. In addition, the delatching pull tab obviates the need for pins or screws, thereby improving manufacturing yield by reducing the likelihood that the module will be damaged during the manufacturing process. In addition, by eliminating pins or screws and a bail from the design, there are fewer moving parts that can wear out over time.

摘要： A method of fuel cell shutdown and start-up is provided. The method of shutdown includes introducing hydrogen gas into the cathode passages to purge a cathode gas from the cathode passages, then introducing air through the cathode and anode passages to remove water droplets and vapor from the fuel cell stacks. The method from fuel cell start-up includes introducing hydrogen gas into the anode and cathode passages to consume/purge oxygen in both the anode and cathode passages, and then introducing a cathode gas into the cathode passages. The introduction of hydrogen into the cathode passages in both the shutdown and start-up procedures allow a rapid draw down of the anode/cathode open circuit voltage and avoids providing a hydrogen/air front while the cathode is filled with air.

摘要： Methods and apparatuses are provided for preventing flex circuits of optical transceiver modules from being damaged during the process of manufacturing and assembling the optical transceiver modules. Preventing the flex circuits from being damaged during the manufacture and assembly processes increases yield and decreases costs. In addition, the methods and apparatuses that are used to prevent the flex circuits from being damaged also allow the processes of forming the mechanical bends and inserting the modules into their respective housings to be automated. Automating these processes further increases yield and decreases costs.

摘要： A consumer input/output (CIO) optical transceiver module, an active optical cable that incorporates a CIO optical transceiver module, and a method for using a CIO optical transceiver module in an active optical cable are provided. In contrast to optical transceiver modules currently used in active optical cables, which utilize parallel arrays of laser diodes and parallel arrays of photodiodes, the CIO optical transceiver module includes two singlet laser diodes and two singlet photodiodes for providing two high-speed transmit channels and two high-speed receive channels, respectively. Because the singlet laser diodes and photodiodes of the CIO optical transceiver module are less costly than the parallel arrays of laser diodes and parallel arrays of photodiodes that are used in known active optical cables, the CIO optical transceiver module can be manufactured at relatively low costs with high quality, and therefore is well suited for consumer applications.
