Abstract: The invention is directed to techniques for forming a fiber optic connection between a first connection assembly that provides alignment members and a second connection assembly that provides grooves such that a central axis of each groove of the second connection assembly is substantially perpendicular with a central axis of a corresponding alignment member of the first connection assembly. Each alignment member/groove pair can be positioned and oriented to control positioning of the first and second connection assemblies relative to each other in a single direction but allow movement in other directions to prevent physical stressing of the connection assemblies.

Abstract: Techniques characterize a circuit breaker device utilizing an apparatus having an energy storage device for storing and releasing a particular amount of energy and a controller. The controller (i) disconnects the energy storage device from an interface and connects the energy storage device to an external power source to store the particular amount of energy in the energy storage device, and (ii) disconnects the energy storage device from the external power source and connects the energy storage device to the interface such that energy is released from the energy storage device through the interface and through the circuit breaker device. The circuit breaker device is deemed to belong to a first category when the circuit breaker device trips in response to the released energy, and a second category when the circuit breaker device does not trip in response to the released energy.

Abstract: The invention is directed to techniques for transferring data using a device driver that is arranged to prevent improper operation of a non-primary routine (e.g., an administrative operation) from causing improper operation of a primary routine (e.g., a data transfer operation). Accordingly, the primary routine can continue to operate properly after a failure of the non-primary routine. In one arrangement, a data communications device transfers data. The data communications device includes a port that couples to a network, and a processor coupled to the port. The data communications device further includes memory, coupled to the processor, that stores a device driver. The device driver has a first set of instructions that directs the processor to perform a data transfer routine that moves data between memory and the port, and a second set of instructions that directs the processor to perform an administrative routine.

Abstract: The invention is directed to techniques for forming a connection between a pin and a circuit board using a pin having protruding portions and grooved surfaces that extend between the protruding portions. The protruding portions (i) prevent the pin from inadvertently slipping through a via of the circuit board, and (ii) maintains the pin's proper position relative to the circuit board via. The grooved surfaces enable gas to vent from a cavity in the via during the solder process thus enabling solder to flow within the via and form a reliable and robust solder joint between the pin and the circuit board via. In one arrangement, the protruding portions and grooved surfaces are at both ends of the pin enabling the pin to be soldered between two circuit board sections. In one arrangement, the pin is simultaneously soldered to both circuit board sections. In another arrangement, the pin is initially soldered to one circuit board section, and subsequently soldered to another circuit board section.

Abstract: A fiber optic backplane has a casing portion and multiple fiber optic ribbons that extend from the same location of the casing portion. Such a backplane is well-suited for high density connections and can operate without significant light energy loss. One arrangement includes multiple optical fibers, a casing and a set of ribbon coatings. The casing holds casing portions of the optical fibers. The set of ribbon coatings holds ribbon portions of the optical fibers in rows to form multiple optical fiber ribbons. Each ribbon coating of the set of ribbon coatings attaches to the casing at a same location of the casing such that the optical fiber ribbons extend from the same location of the casing. The multiple optical fiber ribbons which extend from the same casing location enable higher optical fiber densities than conventional fiber optic backplanes which only have parallel ribbon portions extending from different locations (e.g., centimeters apart) of a central backplane portion.

Abstract: The invention is directed to techniques for controlling access to an optical interface using film having windowed sections and non-windowed sections. The windowed and non-windowed sections are selectively positioned over an optical interface location that holds the optical interface in order to protect the optical interface. Preferably, such positioning occurs in an automated manner such that a technician need not perform an extensive cleaning step each time fiber optic equipment requires handling, e.g., each time a fiber optic connector of a fiber optic component is unplugged and re-plugged. In one arrangement, an optical connector housing holds the optical interface in an optical interface location of the optical connector housing, and a film positioning assembly selectively positions windowed and non-windowed sections of film over the optical interface location in order to selectively expose and protect the optical interface.

In particular, the application configures the controller to assign a usage field to a data element, process the data element using a combination of the multiple resources, and adjust contents of the assigned usage field to identify particular resources of the combination in order to measure resource usage of the computer and detect patterns of resource usage when processing the data element.

Abstract: A method and apparatus are provided for scheduling delays of data in a data communications device within a network. A network policy can be obtained and analyzed to determined various delay categories associated data having various attributes. The delay categories having associated delay values can be used to configure a number of storage locations preferably interconnected in a series. Each storage location has an associated delay. When data arrives, an attribute of the data allows a determination to be made of which delay category and therefore what delay is associated with the data. The data is then deposited into a storage location having an associated delay that generally corresponds to the delay associated with the data. The delay of data is adjusted over time for each storage location, preferably by shifting the data from one storage location to the next.

Abstract: The invention is directed to techniques for inspecting a circuit board having a surface that includes at least one circuit board component. The apparatus includes a base, and a set of reflective members that includes at least one reflective member. Each reflective member of the set of reflective members is (i) supported by the base and (ii) movable relative to the base to enable that reflective member to move to an angle that reflects light from a respective portion of a circuit board component (e.g., a solder region between the component and the circuit board) in a direction away from the surface of the circuit board when the base rests on the surface of the circuit board. Since the base can rest on the surface of the circuit board, a technician does not need to hold the apparatus.

Abstract: A technique provides access to data storage pathways that connect a cluster of nodes to a data storage system in a manner that enables a failover operation to occur from a first node to a second node when the first node suffers pathway degradation forcing the first node to operate significantly slower than previously, even when the first node retains access to the data storage system through one or more available data storage pathways. Such a failover operation from the degraded first node to a second node allows the cluster as a whole to continue performing operations at a rate that is superior to that provided by the degraded first node. In one arrangement, a cluster of nodes connects to the data storage system through multiple sets of data storage pathways. A cluster framework and a set of pathway resource agents operate on the cluster of nodes. In particular, a respective portion of the cluster framework and a respective pathway resource agent operate on each node.

Abstract: The invention is directed to techniques for accessing data within a data storage system having a circuit board that includes both a front-end circuit for interfacing with a host and a back-end circuit for interfacing with a storage device. To move data between the host and the storage device, an exchange of data between the front-end circuit and the back-end circuit can occur within the circuit board thus circumventing the cache of the data storage system. Such operation not only reduces traffic through the cache, but also shortens the data transfer latency. In one arrangement, a data storage system includes a cache, a first front-end circuit that operates as an interface between the cache and a first host, a second front-end circuit that operates as an interface between the cache and a second host, a first storage device (e.g., a disk drive, tape drive, CDROM drive, etc.

Abstract: The invention is directed to techniques for controlling access to an optical interface using a shutter that moves away (e.g., sideways) from the optical interface when exposing the optical interface. Such movement away form the optical interface avoids pushing dirt and debris toward the optical interface when the shutter exposes the optical interface to form an optical connection. Such operation keeps the optical interface clean as well as prevents light from inadvertently escaping from the optical interface that could otherwise cause eye injury (e.g., due to the light intensity). One arrangement is directed to an optical connection system having a first optical connector and a second optical connector.
