| 20090323518 | Ring rapid spanning tree protocol - In a method for enabling facilitation of re-convergence, designation information for a first port of each one of a plurality of bridges in a multi-bridge ring is received and designation information for a second port of each one of a plurality of bridges in a multi-bridge ring is received. The first port of each one of a plurality of bridges is a first direction Ring Rapid Spanning Tree Protocol (RRSTP) port and the second port of each one of a plurality of bridges is a second direction RRSTP port. The first direction around the ring (e.g., a forward direction) is opposite the second direction around said ring (e.g., a backward direction). A first reserved RRSTP MAC address is associated with the first direction port of each one of the bridges and a second reserved MAC address is associated with the second direction port of each one of the bridges. | 12-31-2009 |

| 20090100392 | Securing Authenticity of Integrated Circuit Chip - A system and method are provided for securely manufacturing a device at a foundry. For example, an integrated circuit chip may be securely fabricated at an untrusted foundry by later verifying authenticity of the integrated circuit chip based on a valid usage of an original source code file associated with a semiconductor manufacturing process of the integrated circuit chip. The integrated circuit chip may be authenticated by matching a first set of unique daughter codes generated during fabrication with a second set of unique daughter codes generated independently by some entity other than the foundry. In this way, a trusted electronics integrator may compare the first and second unique daughter codes to nondestructively determine whether the integrated circuit chip is a trusted device or a tampered device. | 04-16-2009 |
| 20110122396 | PHOTONIC MEASUREMENT INSTRUMENT USING FIBER OPTICS - A photonic measurement system, such as an atomic absorption spectrometer, includes source, sample and detection modules that are interconnected by fiber optic cables. A first set of fiber optic cables guides light from one or more light sources in the source module to each of at least two analysis chambers in the sample module. A second set of fiber optic cables guides light from the analysis chambers to a detector in the detection module. The detector provides to a processing sub-system signals that correspond to intensities of the guided light. One analysis chamber is selected to perform a sample analysis at a given time, and the processing sub-system processes the signals associated with the selected analysis chamber as measurement signals. The processing sub-system may further process the signals associated with a given non-selected analysis chamber as reference signals. | 05-26-2011 |

| 20080198106 | Electronic Circuit and Method for Dynamic Piloting of Light Sources in Variable Message Information Panels - The invention concerns an electronic circuit for dynamic command of light sources in variable message information panels. It includes a number of elementary circuits consecutively connected between them, each having at least one LED connected through respective switchable branches, to a feed voltage, to a LED short-circuiting line, to a contiguous elementary circuit and to a component or a control circuit output. Thus, by commanding the switching elements through the control circuit several elementary circuits can be selectively configured as closed circuits, each of which having a chain of LEDs activated in dynamically variable numbers wherein the feed voltage is applied to the feed branch of the first active LED of the chain and the control circuit output is closed on the last active LED of the activated LEDs chain. | 08-21-2008 |
