摘要： A mapping application that returns results for a target location as a function of at least one nearby landmark. The one or more nearby landmarks can be selected based on an expected user familiarity with the landmark, a precision of the landmark and/or a spatial relationship of the landmark with respect to the target location. Although landmarks are an integral aspect of navigation, they have rarely been used within electronic navigation devices. Electronic navigation means for a mobile device or other devices can guide the user along a route using photographs of landmarks together with audio and text instructions that reference these landmarks. This can assist older users who often find their mobility hampered by declines in sensory, cognitive and motor abilities.

摘要： A destination analysis module is described which estimates at least one destination of a user given a partial path taken by the user within a geographic area. The destination analysis module operates by detecting a mode of transportation that a user uses to traverse the path (e.g., automobile, public transportation, walking, etc.). The destination analysis module then loads a model associated with the mode of transportation into a destination prediction module and estimates at least one destination based on the path and the model. The model has various components that depend on the mode of transportation, such as routing network information and prior probability information.
摘要翻译：描述了目的地分析模块，其估计给定用户在地理区域内取得的部分路径的用户的至少一个目的地。目的地分析模块通过检测用户穿过路径（例如，汽车，公共交通，步行等）的运输方式进行操作。目的地分析模块然后将与运输模式相关联的模型加载到目的地预测模块中，并基于路径和模型估计至少一个目的地。该模型具有依赖于运输方式的各种组件，例如路由网络信息和先验概率信息。

摘要： The minimization of the amount of power consumed by an electronic device in acquiring or maintaining network connectivity with a network may extend the battery life of the electronic device. When the electronic device has established a communication connection with a wireless access point, the electronic device cycles a network interface controller of the electronic device between a power on state and a power off state without terminating the communication connection. Accordingly, the electronic device powers on a main processor of the electronic device when the network interface controller detects a beacon during the power on state that indicates the wireless access point has a buffered data frame for the electronic device.
摘要翻译：电子设备在获取或维护与网络的网络连接方面消耗的功率量的最小化可延长电子设备的电池寿命。当电子设备已经建立与无线接入点的通信连接时，电子设备在电源接通状态和断电状态之间循环电子设备的网络接口控制器而不终止通信连接。因此，当在指示无线接入点具有用于电子设备的缓冲数据帧的开机状态期间网络接口控制器检测到信标时，电子设备对电子设备的主处理器供电。

摘要： A user can intend to travel between different locations and employ different traveling manners to reach an intended travel destination. At different points, different devices can be employed for disclosing a route. For instance, as a user walks, a route can be integrated into a personal electronic device, such as a cellular telephone. An evaluation can take place that due to specific route details, for example detailed text, a particular device would be superior for presentment over another.

摘要： The present invention leverages changes in the sensed strength of radio signals at different locations to determine a device's location. In one instance of the present invention, inference procedures are used to process ambient commercial radio signals, to estimate a location or a probability distribution over the locations of a device. In another instance of the present invention, a system utilizes learning and inference methods that are applied to rank vector of signal strength vectors. Moving to such rank orderings leads to systems that bypass consideration of absolute signal strengths in location calculations. The present invention facilitates approximations for locating a device by providing a system that does not require a substantial number of available ambient signal strengths while still providing useful location inferences in determining locations.

摘要： A location-centric signal shadow mapping and storing architecture that creates maps where signals, such as GPS, cannot be seen with ease because of natural or synthetic features such as groups of tall buildings. Such maps are used with other information, such as the dynamics of the sensed velocity that had been seen before the loss of the signals, to reason about the location and likely activities being carried out by one or more people. Inferences can be made based on information about organizations and services associated with structures and locations proximal to the locations where signals were lost. Also, such reasoning can be used to turn off or to reduce the power consumed by the receivers of the location information, potentially with the joint use of accelerometers to identify when significant accelerations occur.

摘要： As a pedestrian travels, various difficulties can be encountered, such as traveling through an unsafe neighborhood or being in an open area that is subject to harsh temperatures. A route can be developed for a person taking into account factors that specifically affect a pedestrian. Moreover, the route can alter as a situation of a user changes; for instance, if a user wants to add a stop along a route.

摘要： An image background maintenance system and method for maintaining a background model of an image sequence by processing on multiple spatial scales. These multiple spatial scales include a pixel scale, a regional scale and a frame scale. The image sequence undergoes pixel processing that determines a current background model and provides an initial pixel assignment as either a background or a foreground pixel. Region processing further refines the initial pixel assignments by considering relationships between pixels and possibly reassigning pixels. Frame processing further refines the current background model by determining whether a substantial change has occurred in the actual background and, if so, providing a more accurate background model.

摘要： The claimed subject matter provides systems and/or methods that facilitate generating an inference about events that may not have yet been observed. Open-world modeling can be used to take a history of observation so as to understand trends over time in the revelation of previously unseen events, and to make inferences with subsets of data that new unseen events will be seen. Thus, inaccuracies associated with predictions generated from incomplete data sets can be mitigated. To yield such predictions, open-world submodels and closed-world submodels that do not allow for previously unseen events can be combined via a model mixture methodology, which fuses inferences from the open- and close-world models.

摘要： An architecture for minimizing calibration effort in an IEEE 802.11 device location measurement system. The calibration technique is based upon a regression function that produces adequately accurate location information as a function of signal strength regardless of gaps in the calibration data or minimally available data. The algorithm takes a set of signal strengths from known room locations in a building and generates a function giving (x,y) as a function of signal strength, which function may then be used for the estimation of new locations. Radial basis functions, which are simple to express and compute, are used for regression. The fact that the algorithm maps signal strength to continuous location makes it possible to skip rooms during calibration, yet still evaluate the location in those rooms.
