Systems and methods which provide mapping an arbitrary outdoor environment and positioning a ground-based vehicle relative to this map. In one embodiment, a land-based vehicle travels across a section of terrain, recording both location data from sensors such as GPS as well as scene data from sensors such as laser scanners or cameras. These data are then used to create a high-resolution map of the terrain, which may have well-defined structure (such as a road) or which may be unstructured (such as a section of desert), and which does not rely on the presence of any “landmark” features. In another embodiment, the vehicle localizes itself relative to this map in a subsequent drive over the same section of terrain, using a computer algorithm that incorporates incoming sensor data from the vehicle by attempting to maximize the likelihood of the observed data given the map.

A method of employing a nanopore structure in a manner that allows the detection of the positions (relative and/or absolute) of nucleic acid probes that are hybridized onto a single-stranded nucleic acid molecule. In accordance with the method the strand of interest is hybridized with a probe having a known sequence. The strand and hybridized probes are translocated through a nanopore. The fluctuations in current measured across the nanopore will vary as a function of time corresponding to the passing of a probe attachment point along the strand. These fluctuations in current are then used to determine the attachment positions of the probes along the strand of interest. This probe position data is then fed into a computer algorithm that returns the sequence of the strand of interest.

A method and apparatus for determining the distance of each pixel or a set of pixels in images acquired by cameras and thus imaging the three-dimensional profiles of objects in the images is described A source of illumination is projected through a mask of two-dimensional pattern onto the objects and images from predetermined and different view points are captured by a camera or cameras. A computer algorithm is used to identify a pixel or a set of pixels in each area of the pattern in each acquired image. The distance of the pixel or the set of pixels in the images is uniquely calculated by using the X, Y coordinates of the pixel or the set of pixels in the images of different view points and the positional relationship of the different view points. The three-dimensional profile of objects in the images is determined by collecting the distance information of each pixel or an area of pixels in the images.

A reference timing signal apparatus with a phase-locked loop (PLL) has a computer algorithm which adaptively models the multiple frequencies of an oscillator following a training period. The oscillator is part of a PLL and the oscillation frequency thereof is controlled in response to the phase detector output. The computer algorithm processes the control signal applied to the oscillator. The computer algorithm updates the characteristics of the model relating to the aging and temperature of the oscillator, using for example, a Kalman filter as an adaptive filter, in accordance with a cumulative phase error in the PLL calculated during a given time interval. By the algorithm, the subsequent model predicts the future frequency state of the oscillator on which it was trained. The predicted frequency of the model functions as a reference to correct the frequency of the oscillator in the event that no input reference timing signal is available. Also, the calculated phase error is stored and is used while no input reference timing signal or accurate predicted frequency value is available. With the model updating algorithm, oscillators of low stability performance may be used as cellular base station reference oscillator, which is based on satellite systems, for example, GPS, GLONASS or Galileo systems.

A statistical patent rating method and system is provided for independently assessing the relative breadth (“B”), defensibility (“D”) and commercial relevance (“R”) of individual patent assets and other intangible intellectual property assets. The invention provides new and valuable information that can be used by patent valuation experts, investment advisors, economists and others to help guide future patent investment decisions, licensing programs, patent appraisals, tax valuations, transfer pricing, economic forecasting and planning, and even mediation and/or settlement of patent litigation lawsuits. In one embodiment the invention provides a statistically-based patent rating method and system whereby relative ratings or rankings are generated using a database of patent information by identifying and comparing various characteristics of each individual patent to a statistically determined distribution of the same characteristics within a given patent population. For example, a first population of patents having a known relatively high intrinsic value or quality (e.g. successfully litigated patents) is compared to a second population of patents having a known relatively low intrinsic value or quality (e.g. unsuccessfully litigated patents). Based on a statistical comparison of the two populations, certain characteristics are identified as being more prevalent or more pronounced in one population group or the other to a statistically significant degree. Multiple such statistical comparisons are used to construct and optimize a computer model or computer algorithm that can then be used to predict and/or provide statistically-accurate probabilities of a desired value or quality being present or a future event occurring, given the identified characteristics of an individual patent or group of patents.

A reference timing signal apparatus with a phase-locked loop has a computer algorithm which adaptively models the multiple frequencies of an oscillator following a training period. The oscillation frequency of the oscillator is controlled in response to a phase detector output. The computer algorithm processes the control signal applied to the oscillator. The computer algorithm updates the characteristics of the model relating to the aging and temperature of the oscillator, using for example, a Kalman filter as an adaptive filter. By the algorithm, the subsequent model predicts the future frequency state of the oscillator on which it was trained. The predicted frequency of the model functions as a reference to correct the frequency of the oscillator in the event that no input reference timing signal is available. In a case of using pre-processing infinite impulse response filters (IIRFs) before the adaptive processor, the time delay caused by the filters are compensated after the adaptive processor. Without pre-processing IIRFs, aging and temperature update rates are adaptively controlled by dynamically changing the rates depending upon the loop condition to achieve a wider tracking bandwidth. With the model updating algorithm, oscillators of low stability performance may be used as cellular base station reference oscillator.

The condition of a fluid piping system is monitored by multiple intercommunicative smart valves, each executing a computer algorithm that designates smart valves as critical or non-critical, compares measurement data versus simulation data, and makes decisions based on the critical-or-noncritical designations and the measurement-versus-simulation comparisons. Initial measurement-versus-simulation comparisons are made for downstream pressure, flow rate, and temperature. If a measurement-versus-simulation discrepancy is found in either the downstream pressure or the flow rate, then the algorithm compares a measurement rupture determinant versus a simulation rupture determinant; if a measurement-versus-simulation discrepancy is found in the rupture determinant, then the smart valve is closed. If a measurement-versus-simulation discrepancy is found in the temperature, then the smart valve, if non-critical, is closed; however, if the smart valve is critical, then the nearest upstream non-critical smart valve is closed. Any measurement-versus-simulation discrepancy results, at least, in an alarm or warning.
