摘要:
A location history is a collection of locations over time for an object. A stay is a single instance of an object spending some time in one place, and a destination is any place where one or more objects have experienced a stay. Location histories are parsed using stays and destinations. In a described implementation, each location of a location history is recorded as a spatial position and a corresponding time at which the spatial position is acquired. Stays are extracted from a location history by analyzing locations thereof with regard to a temporal threshold and a spatial threshold. Specifically, two or more locations are considered a stay if they exceed a minimum stay duration and are within a maximum roaming distance. Each stay includes a location, a starting time, and an ending time. Destinations are produced from the extracted stays using a clustering operation and a predetermined scaling factor.

A location history is a collection of locations over time for an object. By applying a recurring time period to a location history, it can be converted into a stochastic model of the location history. For example, a location history can be reorganized based on intervals that subside a recurring cycle. In a described implementation, training a location history model involves traversing each interval of multiple cycles of a target location history. After each object location at each interval is entered into a training matrix, the intervals can be normalized to determine relative probabilities per location for each interval of a designated cycle. The training and resulting location history model can be Markovian or non-Markovian. Applications include probabilistic location estimation, fusion of location estimates, location-history simulation, optimal scheduling, transition analysis, clique analysis, and so forth.

A circuit breaker can minimize a change in a structure of a case when a material forming a stud is changed. A stud includes a base portion provided in the case and a protruding portion protruding from the case. A cross-sectional area of the protruding portion is more than that of the base portion; thereby a thermal conductivity of the protruding portion increases and the thermal conductivity from the protruding portion to an external conductor connected to the stud increases. In addition, since a surface area of the protruding portion increases, an amount of heat dissipated from the protruding portion increases. In the invention, since dimensions of the base portion inserted into a stud insertion hole of the case are not changed, it is not necessary to change the dimensions of the insertion hole of the case.

The present invention relates includes system and a method for automatically generating short segments of video (or video “cliplets”) from a larger source video. A cliplet has the properties that its length is determined prior to generation and that the cliplet ideally is semantically meaningful and contains a single short event or theme. Generally, the cliplet generation method processes a large source video and generates cliplet results for presentation (such as to a user). Specifically, the method processes the source video to determine editing points and then extracts cliplets from the source video based on the editing points. The extracted cliplets can overlap in time. Cliplet results then are presented, such as to a user. The cliplet generation system includes a video cliplet generator that processes a large source video and generates cliplets in accordance with the cliplet generation method.

A facility for sending enhanced SMS messages is provided. The facility at a sending SMS subscriber unit encodes the original text of an SMS message to produce an encoded SMS message, and transmits the encoded SMS message for receipt by the intended recipient of the SMS message. The facility at a receiving SMS subscriber unit receives the transmitted encoded SMS message and decodes the encoded SMS message to produce the original text of the SMS message. In some instances, the facility at the receiving SMS subscriber unit may not decode the received encoded SMS message and, thus, provide the received SMS message in its received form. In some instances, the facility at the sending SMS subscriber unit may send the original text of the SMS message and have the receiving SMS subscriber unit decode (translate) the original text into a different form.

A photo illumination technology that facilitates user selectable illumination of an existing photo ranging from full artificial flash illumination to ambient light illumination and every gradation between. The technology in one embodiment employs a digital camera feature that captures two photos hundredths of a second apart where one photo is captured in concert with a flash and one is captured with no flash. Compensations are made to reconcile any movement of the subject matter that may have occurred between the two photos and the user is presented with the infinite gradations of illumination on the subject matter when selecting a photo for display or printing.

System and method for estimating and tracking an orientation of a user's face by combining head tracking and face detection techniques. The orientation of the face, or facial pose, can be expressed in terms of pitch, roll and yaw of the user's head. Facial pose information can be used, for example, to ascertain in which direction the user is looking. In general, the facial pose estimation method obtains a position of the head and a position of the face and compares the two to obtain the facial pose. In particular, a camera is used to obtain an image containing a user's head. Any movement of the user's head is tracked and the head position is determined. A face then is detected on the head and the face position is determined. The head and face positions then are compared.

A system and method for facilitating non-linear viewing of media is provided. The system facilitates non-linear viewing of media by providing a scene selector that scans a digitized media and selects a scene in the digitized media and a metadata generator that produces metadata associated with the scenes and relates the metadata to the selected scene. With the scenes annotated with metadata, a playlist generator can generate a playlist of related scenes based on user inputs like queries and a playlist updater can adapt the playlist based on user reaction to the displayed scenes. The scenes can be displayed on a variety of devices exhibiting various levels of intelligence. The displays can be distributed as can the system.
