| 20100281259 | KEY AGREEMENT AND TRANSPORT PROTOCOL WITH IMPLICIT SIGNATURES - A key establishment protocol between a pair of correspondents includes the generation by each correspondent of respective signatures. The signatures are derived from information that is private to the correspondent and information that is public. After exchange of signatures, the integrity of exchange messages can be verified by extracting the public information contained in the signature and comparing it with information used to generate the signature. A common session key may then be generated from the public and private information of respective ones of the correspondents. | 11-04-2010 |

| 20120257758 | STRENGTHENED PUBLIC KEY PROTOCOL - A method of determining the integrity of a message exchanged between a pair of correspondents. The message is secured by embodying the message in a function of a public key derived from a private key selected by one of the correspondents. The method comprises first obtaining the public key. The public key is then subjected to at least one mathematical test to determine whether the public key satisfies predefined mathematical characteristics. Messages utilizing the public key are accepted if the public key satisfies the predefined mathematical characteristics. | 10-11-2012 |

| 20090050736 | LANDING GEAR - A semi-levered landing gear for an aircraft comprises a main shock absorber strut ( | 02-26-2009 |
| 20120091271 | LANDING GEAR - A semi-levered landing gear for an aircraft includes a main shock absorber strut, a bogie beam and an auxiliary actuator mechanism. The bogie beam extends fore and aft of an airframe of the aircraft with forward and aft axles for respective forward and aft wheels, and a main pivot between the forward and aft axle pivotally connected to the lower portion of the main shock absorber strut. The auxiliary actuator mechanism includes a spring unit pivotally connected at a lower end to an auxiliary pivot on the bogie forward of the main pivot, and at an upper end to an anchor point offset from the pivot connection of the upper portion to the aircraft fuselage. During stowing the strut and spring unit pivot together about different pivot points, causing a relative longitudinal movement between the main pivot and auxiliary pivot that further tilts the bogie beam to a stowing position. | 04-19-2012 |
| 20120112001 | LANDING GEAR - An auxiliary mechanism includes a lever unit, a spring unit and a positioning unit. One of the units pivotally connects to the upper portion of a main shock absorber strut so as to pivot between a predetermined lower position for take-off and landing and an upper position. Another unit pivotally connects at an upper end to the upper portion of the main shock absorber strut and pivotally connects at a lower end to the first unit. A third unit pivotally connects at a lower end to the bogie beam at an auxiliary pivot and connects at an upper end to the lever. The positioning unit assumes either a contracted state or extended state for taxiing, take-off and landing, and assumes the other state for stowing the landing gear after take-off. The spring unit provides spring resistance to pivotal movements of the bogie beam about the main pivot during taxiing. | 05-10-2012 |
| 20120119025 | LANDING GEAR - An auxiliary actuator mechanism includes a lever, a spring unit and a control linkage. The lever is pivotally connected to the upper portion of a main shock absorber strut, and pivotable between an upper position for take-off, and a lower position. The spring unit is pivotally connected at an upper end to the lever and at a lower end to the bogie at an auxiliary pivot forward of the main pivot. The control linkage is connected between the lever and the upper portion of the main shock absorber strut to define the upper predetermined position of the lever. The control linkage is connectable to an anchor point that moves relative to the upper portion of the main shock absorber strut during stowing, and is operated by initial stowing movement of the stowing mechanism to lower the lever from the upper position to a stowing position. | 05-17-2012 |

| 20110261632 | Combined Write Assist and Retain-Till-Accessed Memory Array Bias - Bias circuitry for a static random-access memory (SRAM) with a retain-till-accessed (RTA) mode and with write assist bias in a normal operating mode. The memory is constructed of multiple memory array blocks of SRAM cells. Bias devices are associated with each memory array block, and associated with one or more columns. Each bias device includes a diode-connected transistor in parallel with a shorting transistor, between a power supply voltage and a power supply bias node for cells in its column or columns. The shorting transistor receives control signals from control logic so that the diode-connected transistor for each column is shorted during read cycles, and in write cycles in which its columns are not selected; in write cycles in which its columns are selected, the shorting transistor in the bias device is turned off, so that a reduced power supply voltage is applied to the selected column. The shorting transistors for all columns in the block are turned off in the RTA mode. An additional transistor in series with the diode-connected transistor may be included, to enable a floating power supply bias mode. | 10-27-2011 |
| 20120266123 | COHERENT ANALYSIS OF ASYMMETRIC AGING AND STATISTICAL PROCESS VARIATION IN ELECTRONIC CIRCUITS - Coherent analysis of asymmetric aging and statistical process variation. A method of designing a circuit includes preparing an initial netlist of components in the circuit. A plurality of components is selected from the initial netlist by a first statistical process. Further, a process variation netlist is prepared by replacing a plurality of initial operating parameters of the plurality of components with a plurality of process variation operating parameters. A plurality of high stress components is then identified in the process variation netlist and an aged netlist is prepared by replacing a set of operating parameters of the plurality of high stress components with a set of degraded operating parameters. The circuit is simulated using the aged netlist. The method also includes modifying the initial netlist according to a result of simulation and repeating the foregoing steps until a desired circuit performance is obtained. | 10-18-2012 |
