When the virtual ray intersects with the location of a controllable object whose identity and location are known, the handheld controller identifies the object and accepts remote-control input from the user for controlling that object. Using the handheld controller, the user may control any controllable object having a known identity and location in space, and may control virtual as well as physical objects. |

Context-aware component styling in user interfaces of electronic devices
The disclosed embodiments provide a system that renders a view component in a user interface of an application on an electronic device. During operation, the system generates, from content describing a view for display in the user interface, a styling path that includes a position of the view component in a content hierarchy of the view. Next, the system selects, by a styling component executing on a processor in the electronic device, a style context for the view component from a collection of style contexts by matching at least a subset of the styling path to an identifier for the style context. The system then uses the style context to render the view component in the view. |

When the route change is determined not to be achievable by the course-change achievability determiner, the automatic drive controller causes the own vehicle to keep automatically driving along the traveling route determined before the reconstruction. |

Integrated device for nucleic acid detection and identification
A disposable assay platform for detecting a target nucleic acid comprising multiple chambers and a method for operating the assay platform. Solutions containing the target nucleic acid move from one chamber to the next chamber by opening a vent pocket. The resulting pressure change enables the solution to flow to the next chamber. The platform comprises an electronic layer and one or more fluid layers bonded together. All heating operations can be performed by using resistive heating elements in the platform. All cooling operations are preferably passive. The platform is preferably operated when in a vertical orientation and can be docked to an external docking station that controls the operation of the platform. |

Delayed pyrophosphorolysis activated polymerization
Minimal-copy-ratio of templates is a problem in detecting early stage cancer where minimal copies of somatic cancer-specific mutations are targeted in the presence of large copies of wildtype genome DNA, commonly a 1/10,000 or even less minimal-copy-ratio between the mutant target and wildtype control templates. To overcome this problem, delayed pyrophosphorolysis activated polymerization (delayed-PAP) was developed which can delay product accumulation of the wildtype control to a much later time or cycle by up to 15 cycles or by 30,000 folds. In the multiplex format, delayed-PAP is particularly useful to amplify not only the wildtype control but also mutant target templates accurately and consistently in the minimal-copy-ratio situation. |

Nucleic acid isothermal self-amplification method
Provided is a nucleic acid isothermal self-amplification method comprising, adding suitable palindrome complementary sequences at both ends of a target template to form a stem-loop structure spontaneously, and providing reagents and conditions as needed to perform self-amplification. The method does not require addition of additional amplification primers. The reagent comprises a DNA polymerase having a strand displacement activity. The method does not rely on exogenous amplification primers for amplification, has a constant amplification temperature without a complex temperature control equipment, and achieves rapid amplification. The amplification product is a long single-stranded DNA of a continuous complementary sequence and can be applied to special occasions. In addition, the amplification has no GC bias. |

Linked ligation
The invention generally relates to capturing, amplifying, and sequencing nucleic acids. In certain embodiments, copies of the sense and antisense strands of a duplex template nucleic acid are captured using linked capture probes and multiple binding and extension steps to improve specificity over traditional single binding target capture techniques. Methods of seeding sequencing clusters with sense and antisense strands of a target nucleic acid are also disclosed including identifying the strands using sense-specific barcodes and confirming base calls using two sense-specific sequencing reads. Linked adapters may be used to increase adapter ligation selectively or efficiency and yield. |

Reagents and methods for the analysis of linked nucleic acids
Reagents and methods for the analysis of nucleic acids (e.g. genomic DNA) of circulating microparticles (i.e. microparticles originating from blood) are provided. The methods comprise linking at least two fragments of a target nucleic acid of a circulating microparticle to produce a set of at least two linked fragments of the target nucleic acid. In the methods, fragments of a target nucleic acid may be linked by techniques such as barcoding, partitioning, ligation and/or separate sequencing. The sequencing of a set of linked fragments provides a set of informatically linked sequence reads corresponding to the sequences of fragments from a single microparticle. |

Rapid, low-sample-volume cholesterol and triglyceride assays
Reagents, assays, methods, kits, devices, and systems for rapid measurement of cholesterol and cholesterol sub-fractions from a blood sample are provided. Total cholesterol, low density lipoprotein cholesterol, and high density lipoprotein cholesterol can be measured in a single assay using kinetic measurements, under conditions in which cholesterol sub-species are converted to a detectable product at distinct rates. The detectable product is measured at different times after assay initiation. A lipase, cholesterol esterase, cholesterol oxidase and a peroxidase may be used together to produce colored product in amounts directly proportional to the quantity of cholesterol converted. Methods for calculating very-low density lipoprotein cholesterol levels by further including triglyceride measurements are disclosed. Assays may be performed in a single reaction mixture, allowing more accurate and precise cholesterol determinations, including ratios of cholesterol sub-fractions to total cholesterol, at less expense, than would be expected by performing several different assays in different reaction mixtures. |

Devices and assays for estimating microbial load and differentiating microbial populations
Devices, methods, kits and means for easy, accurate, and fast estimation of soil microbial load, including fungal load, and fungal to bacterial ratio are described. The methods include extracting soil biomass into an extraction fluid to obtain a soil extract and detecting the fungal fraction, the bacterial fraction, and the fungal to bacterial ratio in the soil extract. The devices typically include microBIOMETER®, devices for particle size discrimination, and devices for absorbance and reflectance detection. The difference in microscopic sizes or spectroscopic absorbance of the fungal particles relative to those of the bacterial particles is used to compute the contribution of each type of particle to the biomass. In one example, the relative coverage of the microBIOMETER® device membrane by the fungal and/or bacterial particles can be measured by and then calculated using a cell phone camera and application. |
