Abstract: A method and apparatus for increasing performance of Data Encryption Standard (DES) and Triple DES (3DES) cipher operation is provided. A critical path through a plurality of rounds in a multi-round cycle to perform a cipher operation is reduced by reducing the number of exclusive OR (XOR) operations in the critical path. An R state element is expanded to 48-bits and each round stage uses the 48-bit expanded R state element which results in a reduction of the number of XOR operations to one per round in the cipher operation plus one additional XOR operation per cipher operation. In addition logic organization is symmetric which further increases the overall performance of DES and 3DES.

Abstract: A stop mechanism advantageously combined with a manhole cover includes a holder body having a passage which slidably receives a stop member able to be cammed in and out upon advance or retraction of a threaded drive member having an enlarged tip engaged with a down sloping channel formed in the stop member. Upper sides of the channel engage the tip upon reversal of the drive member to cam the stop member back into the holder body. The stop member when extends prevents removal of the cover from being blown completely free of the manhole vault structure in the event of an explosion.

Abstract: A distributed sequential method and system for detecting and identifying radioactive contraband from highly uncertain (noisy) low-count, radionuclide measurements, i.e. an event mode sequence (EMS), using a statistical approach based on Bayesian inference and physics-model-based signal processing based on the representation of a radionuclide as a monoenergetic decomposition of monoenergetic sources. For a given photon event of the EMS, the appropriate monoenergy processing channel is determined using a confidence interval condition-based discriminator for the energy amplitude and interarrival time. If accepted the parameter values of the photon event are used to update the parameter values using an LKF for the energy amplitude and a bootstrap PF for the interarrival times. These parameter estimates are then used to update a measured probability density function estimate for a target radionuclide.

Abstract: In an automatically switched optical network operating according to a wavelength plan, the wavelengths are assigned to an optical path based on availability, performance and SRS wavelength coupling reduction. First, the wavelengths are grouped in static bins based on their reach versus cost performance, and each bin assumes a ?Q of a middle wavelength. Then, the bins are moved into subsets of dynamic bins, constructed using bin constraints that account for the particulars of the respective optical path. The path is characterized taking into account the wavelength currently accessing at the end nodes, and the wavelength tandeming through the end nodes. Wavelength selection starts with the bins that satisfy the maximum number of constraints, and the wavelengths are checked sequentially against wavelength constraints; relaxed constraints are also applied when it is not possible to exactly satisfy one or more constraints.

Abstract: A hydrogen storage tank for containing solid-state hydrogen storage media, and method for determining the hydrogen fill level in the tank. The tank has at least one compartment for storing the storage media, passages for transporting hydrogen gas to and from the compartment, and a heat distribution system for establishing a substantially uniform temperature in the storage media. A look-up table is generated for the tank that relates hydrogen pressure changes in the tank versus hydrogen fill levels in the tank as a function of temperature. The tank is filled to full capacity by adsorbing hydrogen on the storage media. Thereafter, hydrogen is released from the storage media for a time period during which there is a substantially constant demand on the tank, the change in pressure of the released hydrogen gas is measured, and the look-up table is applied to determine the hydrogen fill level in the tank.

Abstract: A labeling method for marking a product with invisible information. The label includes a removable laminate formed from a light transmissive layer, and a light transmissive adhesive that detachably affixes the label to a product. The label includes an invisible marker that contains information, detectable by light of selected wavelength. The amount of marker selected is sufficient to allow information in the marker to be detected only when the laminate is affixed over a surface with a selected optical background. The label laminate is removed from the surface of the product and affixed to a surface having the selected optical background and is exposed to light that renders the information in the marker detectable. The method allows covert information in the label laminate to be reliably detected and read with the use of minimal quantities of marker material.
