Abstract: A method includes buffering an initial amount of data of a data set transmitted from a MAC. When an amount of time for data associated with the data set to fill a PHY buffer approaches an amount of time for the far-end PHY to transition from the second far-end PHY power state to the first far-end PHY power state, buffering a remaining amount of data of the data set transmitted from the MAC and transmitting the data to a far-end PHY after the far-end PHY transitions between a second and first far-end PHY power state. When the amount of time for data associated with the data set to fill the buffer exceeds the amount of time for the far-end PHY to transition from the second to the first far-end PHY power state, transmitting a data delay indicator to the MAC to preempt the MAC from transmitting the remaining amount of data.

The technique further involves, for each application identified by the user, providing an application service to that application to support operation of that application, the application service being separate from operating system services and security protection services provided by the electronic system.

Abstract: An electronic device provides electronic access to a dataset representing meaningful information. The electronic device generates a first subset permutation based on a first subset of the dataset, and generates a second subset permutation based on a second subset of the dataset. Each subset of the dataset includes a series of data elements having a particular fixed bit-length. The first subset permutation includes a rearrangement of the series of data elements of the first subset. Similarly, the second subset permutation includes a rearrangement of the series of data elements of the second subset. The electronic device further forms an electronic aggregation based on the first subset permutation and the second subset permutation, and generates an aggregation permutation based on the electronic aggregation. The aggregation permutation includes a rearrangement of portions of the electronic aggregation. The meaningful information is fully recoverable from the aggregation permutation.

Abstract: An in-band protocol transport carries command-response protocol communications between first and second functional components of a storage input/output (I/O) interface stack, for example to control encryption-related processing of storage I/O commands. A storage read command used as a protocol transport message has protocol data in a read data buffer, and predetermined read address information, such as a prime-numbered starting block address and a small, odd-valued length value, unlikely to occur in normal (non-transport) storage read commands. The second functional component determines that the storage read command contains the predetermined read address information, indicating that the storage read command is a protocol transport message rather than a normal read. For greater confidence, it also determines that the protocol data in the read data buffer includes protocol identification data such as a protocol signature.

Abstract: A device for drawing melt-spun filaments for forming a spunbonded fabric includes at least one guide member. The filaments are guided through a slot-shaped nozzle, onto which compressed air is applied, and which conveys the filaments through the drawing nozzle. Guide members are provided on both sides of the slot on the base of the slot-shaped outlet, which cause a uniform structure of the fabric due to their shaping. This is achieved when a guide member has a plurality of notches parallel to the conveying direction, and the opposite guide member has a plurality of bores, which passively connect the space between the guide member with the environment.

Abstract: A process and apparatus for automated testing of authentication tokens is disclosed which verifies the physical functioning of the tokens and the validity of the one-time passcodes (OTPs) displayed by the tokens during testing. The testing is automated to allow for large quantities of tokens to be tested in a single procedure, and also separates rejected tokens according to the particular failed test process identified with the token. In one embodiment, a rotary table is provided for testing, the table having multiple positions for performing different test procedures and for separating rejected tokens according to the particular test failed.

Abstract: A method is provided to allow for encryption keys to be safely vaulted and for restarts after system failures, even when an external key server is not accessible. In one embodiment, the encryption keys are stored in memory in an encrypted format, the encryption keys being encrypted with a key encryption key (KEK). The data stored in a write cache may be encrypted and written to a vault, protecting it from unauthorized access, but the key table may be written directly to the data vault without need for any further encryption. Because the encryption keys are themselves encrypted, the encryption keys are protected from unauthorized access, ensuring the security of all the encrypted data stored on disk. This embodiment allows the data storage system to be restarted without accessing an external key server. In another embodiment, the KEK is stored in persistent storage within the data storage system, allowing for unattended restart. To enhance security, the KEK may be stored in ROM in a hardened location.

Abstract: An explosive device detection system includes sensors and base station that detect and report on suspected improvised explosive device (IED) emplacement activity within the area. When disposed within a geographic area, each sensor forms part of a wireless communications network which allows communication among neighboring sensors. As a sensor detects activity in its proximity, such as activity that indicates emplacement of an IED, the sensor transmits a reporting signal through the network to the base station. The base station is operable to detect if the signals received from the sensors are indicative of IED emplacement activity or some other activity that is not typically associated with IED emplacement activity. In the event that the base station detects activity that is indicative of IED emplacement activity, the base station can direct mobile response units to take immediate responsive action to prevent detonation of the IEDs or apprehend the perpetrators in the act.

In order to obtain cooling adapted to the particular filament titer, the blowing onto the filaments can be set by selecting one of several operating positions, where to change the operating position of the blower wall it is moved in the direction towards the filaments or in the direction away from the filaments.

Abstract: A method provides a storage service, and is performed on a set of computerized devices. The method includes connecting the computerized devices to a computer network. The computerized devices include direct attached storage devices (e.g., SCSI disk drives). The method further includes configuring the computerized devices to behave as hosts which individually and logically couple to an array of storage devices through a shared bus, and performing a host IO operation among the computerized devices. The host IO operation involves accessing data from a particular computerized device through the computer network to the direct attached storage devices of the computerized devices in lieu of accessing the data from the particular computerized device through an actual shared bus to an actual array of storage devices.

Abstract: A method is provided for effectively managing encryption keys. A storage processor requests a key associated with a particular object ID associated with a particular device address range from a key server. The key server provides a unique key associated with the object ID. Old keys may be deleted either upon a determination by the storage processor that the key is no longer needed, or upon a signal from the key server indicating that the key is to be deleted. In either case, the storage processor deletes the key from all locations in memory and sends a confirmation signal to the key server. The key server then lists the key as disabled for possible future re-use. Embodiments are also directed to apparatus for use in practicing the method.

Abstract: A method and apparatus for changing power class for a powered device are provided. During operation, a powered device, such as an IP telephone, receives power from a power source via a PoE device. In the event that the powered device detects connection to a second powered device, such as an IP telephone module, the powered device transmits a classification signal to the power source. Based upon the classification signal, the power source performs a powered device classification procedure to reclassify the powered device, such as according to an IEEE 802.3af standard, and provide an increase amount of power to the powered device. The powered device, in turn, provides a portion of the power to the modular device. The modular powered device, therefore, receives power directly from the first powered device and does not require additional equipment in order to operate.
