摘要:
A computer-implemented method includes obtaining road sensor data reflecting speeds of traffic on road segments, transforming the road sensor data using vehicle probe data for the road segments reflecting vehicle speeds, and producing speed estimates for the road segments using the transformed road sensor data. The method can further include determining speeds for road segments between road sensors by smoothing data from sensors near the road segments.

This specification describes technologies relating to geographically localizing mobile communication devices. In general, one aspect of the subject matter described in this specification can be embodied in a method that includes receiving information corresponding to a location of a wireless landmark in a mobile communication network. The method also includes communicating with the wireless landmark to estimate the location of a first node in the mobile communication network proximate to the wireless landmark. Other embodiments of this aspect include corresponding systems, apparatus, and computer program products.

Various aspects can be implemented to provide personalized traffic alerts. In general, one aspect can be a method that includes identifying, at a computing device, an area of interest associated with information request. The method also includes submitting to a remote computing system a request associated with the area of interest that does not identify the area of interest. The method further includes receiving, in response to the submitted request, a result corresponding to a super-area that is larger than, but includes, the area of interest. The method additionally includes identifying information within the result corresponding to the area of interest. Other implementations of this aspect include corresponding systems, apparatus, and computer program products.

Systems and methods for improving the delivery of interactive advertisements are discussed herein. Systems and methods include approaches and solutions for boosting the rank of certain ads and/or ad types based on a combination of their interaction type and an ad interaction history for a given user, vertical, or aggregate indicator. Systems and methods also include suppressing ads unlikely to be interacted with from ranking and format boosting based on such ad interaction history.

This invention provides a process for the detoxification of chemical agents including chemical warfare agents such as sulfur mustards, nitrogen mustards, nerve agents of G and V type, lewisite and adamsite by reacting the chemical agents with hydroxyl radicals at a pH greater than 7.0 to detoxify the agents and to render them suitable for disposal. The process can be used on-site and can be easily scaled to fairly large sizes.

Compounds, compositions and methods are provided for modulating the expression of transthyretin. The compositions comprise oligonucleotides, targeted to nucleic acid encoding transthyretin. Methods of using these compounds for modulation of transthyretin expression and for diagnosis and treatment of diseases and conditions associated with expression of transthyretin are provided.
摘要:
The invention is addressing the problem of efficient formation and maintenance of piconets with assistance from the master of an already existing piconet. The master of an existing piconet initiates the formation of a new helper piconet by at least two of its slaves. One of the slaves of the existing piconet becomes the master of the newly formed helper piconet and the other slave becomes a slave of the helper piconet. This process can be used to expand the number of Bluetooth devices that can use an Internet access point. It can also be used to permit two slave devices to communicate directly with one another so as not to unnecessarily use bandwidth available through the master. Finally, the method and system could be used to provide a method of efficient hand-off from one piconet to another.
摘要:
A body implantable lead system includes an over-the-wire lead with a longitudinally extending lumen. A hollow stylet having an outer peripheral surface is introduced into the lumen and an annular resilient blood seal within the lumen may be sealingly positioned between the outer peripheral surface of the stylet and the lead to prevent flow of blood beyond the blood seal and into the lumen in a proximal direction. A guidewire is slidably received within the hollow stylet and includes a tip end which may project through the passage at the distal end of the lead such that relative movement of the guidewire and stylet within the lead is enabled while avoiding friction between the blood seal and the guidewire. Either the guidewire or the stylet may be preshaped for proper placement of the lead for engagement with the body tissue and surrounded by a semi-rigid retractable sheath.
