| 20120058494 | Quenched Dendrimeric Dyes for Florescence Detection - The present invention presents designs for high extinction quenched “dyedrons” that can be activated by conversion of a single acceptor/quencher in the molecular assembly to a fluorescent state.

Reflectivity data is captured using the light-based sensing device. A light intensity signal is generated based on the captured reflectivity data. The light intensity signal is convolved with a differential filter for generating a filter response that identifies a candidate lane marker region and ground segment regions juxtaposed on each side of the candidate lane marker region. A weighted standard deviation of the data points within the identified candidate lane marker region and weighted standard deviation of the data points within the ground segment regions are calculated. An objective value is determined as a function of the respective weighted standard deviations. The objective value is compared to a respective threshold for determining whether the identified candidate lane marker region is a lane marker. | 01-21-2010 |
| 20100013615 | Obstacle detection having enhanced classification - A method and system for sensing an obstacle comprises transmitting an electromagnetic signal from a mobile machine to an object. A reflected electromagnetic signal is received from the object to determine a distance between the object and the mobile machine. An image patch is extracted from a region associated with the object. Each image patch comprises coordinates (e.g., three dimensional coordinates) associated with corresponding image data (e.g., pixels). If an object is present, image data may include at least one of object density data and object color data. Object density data is determined based on a statistical measure of variation associated with the image patch.

| 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 |
| 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 |
