| 20090064769 | System and Method for Determining a Center of Gravity of an Aircraft - According to one embodiment of the disclosure, a method of determining a center of gravity of an aircraft includes receiving a strut length for each of the gears of an aircraft, determining an arm length for each of the gears, and determining a center of gravity of the aircraft based on a relationship between the center of gravity and respective arm lengths for each of the gears. The arm length of each of the gears is determined according to the strut length of a gear strut of a respective gear and a relationship between the strut length of the gear strut to another gear of another aircraft and the arm length of the respective gear. | 03-12-2009 |

| 20090248370 | Method and Apparatus for Applying "Quasi-Monte Carlo" Methods to Complex Electronic Devices Circuits and Systems - The invention discloses a “Quasi-Monte Carlo” method originally intended for computational finance applications and applies said method to statistical circuit analysis. In doing so, it provides a means to efficiently and effectively detect and/or predict relatively rare failures or events to a wide range of industrial circuits and systems. The approach to the invention involves the representation of circuit metrics as a large multi-dimensional integral. This invention estimates such statistical circuit metric integrals by sampling the statistical variable space using a so-called “low-discrepancy sequence.” This is similar to the Monte Carlo method, the main difference being the method of sampling the variable space. Compared with standard Monte Carlo simulation, this technique, “Quasi-Monte Carlo Methods,” gives similarly reliable estimates of the result, but requiring many fewer samples of the circuit or system being evaluated. In practice, speedups of 2× to 50× across a range of practical examples are observed. | 10-01-2009 |
| 20090248387 | Method and apparatus for sampling and predicting rare events in complex electronic devices, circuits and systems - The invention provides methods for enhancing circuit reliability under statistical process variation. For highly replicated circuits such as SRAMs and flip flops, a rare statistical event for one circuit may induce a not-so-rare system failure. To combat this, the invention discloses the method called “Statistical Blockade,” a Monte Carlo-type technique that allows the efficient filtering—blocking—of unwanted samples insufficiently rare in the tail distributions of interest, with speedups of 10-100×. Additionally, the core Statistical Blockade technique is further extended in a “recursive” or “bootstrap” formulation to create even greater efficiencies under a much wider variety of circuit performance metrics, in particular two-sided metrics such a Data Retention Voltage (DRV) which prior Monte Carlo techniques could not handle. | 10-01-2009 |

| 20110115463 | DIFFERENTIAL FET STRUCTURES FOR ELECTRICAL MONITORING OF OVERLAY - A method and apparatus for determining overlay includes an array of electronic devices having structures formed in a plurality of layers and such that a device on a first end of the array includes an offset from a position of a device on a second end of the array. A measurement device is configured to measure electrical characteristics of the devices in the array to determine a transition position between the electrical characteristics. A comparison device is configured to determine an overlay between the layers based on a device associated with the transition position. | 05-19-2011 |

| 20110172979 | CIRCUIT-LEVEL VALIDATION OF COMPUTER EXECUTABLE DEVICE/CIRCUIT SIMULATORS - A method is disclosed for evaluating a model, characterized as being a computer executable device and circuit simulator. The method includes accepting measured parameters of devices, which devices are essentially identical with, or are actually from, a simulated circuit instance. The model is executed with adjusted input parameters to generate simulated values for properties of the circuit instance. These simulated values are compared with measured values of the same properties. The goodness of the model is determined based on the degree of direct, or statistical, agreement between the simulated and measured values. | 07-14-2011 |

| 20100031186 | Accelerated Panning User Interface Interactions - A computer-implemented user interface method includes displaying on a touch screen a potion of a large scale graphical space that is at least multiples larger than the device display, receiving from a user of the device an input to pan within the graphical space, automatically generating a pop up graphical panning control in response to receiving the user input, and receiving a user input to the panning control and providing panning in the graphical space, wherein movement of the panning control in a single selection is able to pan the display across a substantial portion of the large scale graphical space. | 02-04-2010 |
| 20110040996 | PROVIDING A USER WITH FEEDBACK REGARDING POWER CONSUMPTION IN BATTERY-OPERATED ELECTRONIC DEVICES - Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing a user with feedback regarding power consumption in a battery-operated electronic device. In one aspect, a method performed by data processing apparatus includes identifying, using the data processing apparatus, usage of a hardware component of a battery-operated electronic device that includes the data processing apparatus, attributing the usage of the hardware component to the hardware component or to a software application that uses the hardware component, recording, using the data processing apparatus, a power consumption resulting from the usage, and presenting power consumption feedback to a user using the data processing apparatus. The power consumption feedback identifies the hardware component or the software application of the electronic device and the power consumption resulting from the usage. | 02-17-2011 |
