摘要:
Step detection and step length estimation techniques include detecting salient points in sensor data of one or more sensors. A step frequency is estimated based on a time interval between the detected salient points. A step length of the step may then be computed based on a nonlinear combination of the estimated step frequency and a function of the sensor data, and/or a step model. Alternatively, the step length of the step may be computed based on a combination of a nonlinear function of the estimated step frequency and a (linear or nonlinear) function of the sensor data, and/or a step model.

Some implementations provide techniques and arrangements for distance measurements between computing devices. Some examples determine a distance between devices based at least in part on a propagation time of audio tones between the devices. Further, some examples determine the arrival time of the audio tones by performing autocorrelation on streaming data corresponding to recorded sound to determine a timing of an autocorrelation peak indicative of a detection of an audio tone in the streaming data. In some cases, cross correlation may be performed on the streaming data in a search window to determine a timing of a cross correlation peak indicative of the detection of the audio tone in the streaming data. The location of the search window in time may be determined based at least in part on the timing of the detected autocorrelation peak.

Methods and apparatuses are provided for facilitating content-based image retrieval. A method may include determining a selected target image. The method may further include generating a candidate region of interest set including one or more regions of interest within the target image. The method may additionally include determining a recommended region of interest set including one or more recommended regions of interest selected from the candidate region of interest set based at least in part upon evaluation criteria. The evaluation criteria may be determined based at least in part upon analysis of maintained region of interest-based searching history. The method may also include providing the recommended region of interest set for user selection of one or more target regions of interest from the recommended region of interest set as query criteria for searching an image library for one or more result images. Corresponding apparatuses are also provided.

Some implementations disclosed herein provide techniques and arrangements to enable interactive zones. For example, some implementations detect that a user has entered a zone associated with a physical object, where the zone is created via magnetic induction. In response to detecting that the user has entered the zone, some implementations send a virtual object representation of the physical object to a user device (e.g., a wireless phone) associated with the user. The user may interact with the virtual object, including selecting a command associated with the virtual object. Selecting the command may cause the physical object to perform one or more actions. In some implementations, a result of the physical object performing the one or more actions is sent to the user device.

A system includes, but is not limited to, a physical product associated with a device-readable indicator, the device-readable indicator associated with a first potential-ecological-impact quantification and with a first-disposal-mode identifier describing a first mode of disposing of at least a first portion of the physical product. In addition to the foregoing, other aspects are described in the claims, drawings, and text forming a part of the present disclosure.

Systems and methods for providing ecological impact quantification identifiers may implement operations including, but not limited to computing at least one ecological impact quantification associated with at least one life-cycle phase of a product; and means for assigning at least one of a positive ecological impact status, a negative ecological impact status and a neutral ecological impact status with a user account according to the at least one ecological impact quantification.

An implementation of location estimation using image analysis is described. In this implementation, an image of a place is obtained and matched with previously stored images. The matching may be achieved by employing methods based on key feature extraction algorithm, color histogram analysis, pattern matching or other image comparison techniques. Upon determining a match, the location information associated with the image provides the location. The location information may be in the form of location tags or location keywords and the location information may be used by the user or other applications for the purposes of location determination. The technique allows for the user to enter location information. The location information may be assigned to the previously stored images residing in local and remote databases for users and applications to assign information or keywords to images.

The claimed subject matter provides a system and/or a method that facilitates managing a number of active servers in a cluster. A forecast component can predict at least one of login rate or number of connections in the cluster at a future time. A dynamic load analysis component can evaluate dynamic behaviors in login rate and number of connections in the cluster as a result of load dispatching. Moreover, a provisioning component can determine a number of servers in the cluster needed based at least in part on the prediction and dynamic behavior analysis. In addition, the provisioning component can include an additional margin in the number of servers needed in accordance with multiplicative factors.
