摘要:
Methods and apparatuses for estimating a user's altitude with respect to the mean sea level are provided. According to some aspects, the present invention is able to estimate altitude in both open sky as well as in degraded GPS signal environments such as dense urban canyon environments where GPS performance is affected by fewer available satellites and/or multipath error. According to other aspects, the present invention uses data from a pressure sensor to estimate altitude, either with or without the use of GPS aiding data. According to further aspects, estimated altitude is integrated with other types of dead reckoning data to provide user context detection pertaining to changes of altitude.

A method and apparatus of detecting and using motion modes in a mobile device is described. Movement data is collected from an inertial motion unit (IMU) of the mobile device and compared to two or more sets of training data, each set of training data corresponding to a different motion mode. Then, a motion mode is determined to be the current mode of the mobile device on the results of the comparison. The motion mode is used by the mobile device in a variety of applications.

The present invention is related to detecting location of a navigation device using sensor data analysis, where the sensor is coupled to the navigation device. A hierarchical algorithm is used for making a series of decisions regarding the location of the navigation device, with each decision corresponding to a class among a plurality of classes related to the possible motion modes and/or precise location of the device, including the location of the device with respect to a person's body. By accurately identifying the device location, the hierarchical algorithm facilitates in providing relevant contextual information, thereby enhancing situational awareness.

A drug delivery device has been designed to directly deliver an agent to the ovaries through direct contact with the fallopian tubes. The device consists of three main components: a tubular inserter, a cylindrical chamber and a plunger. The device is a single-use applicator designed in a shape similar to a tampon to facilitate its insertion through the vagina and into the uterus. Positioning of the device centrally in the uterus is accomplished through the use of ultrasound. The chamber is inserted into the tubular inserter. Adjusting the length of the chamber inserted into the tubular inserter controls the amount of tubing released from the apertures in the tubular inserter. Ultrasound is used to ensure the proper placement of each tube at the entrance of each fallopian tube. The plunger is inserted into the chamber and adjustment of the plunger controls the amount of the agent released into the tubes.

Methods and arrangements for creating and building subcategories in a user-based voice application. User posts are appended to a category in a voice application and subdivision of the category is prompted upon satisfaction of a first condition. The category is designated as a parent category, and at least one subcategory nomination are solicited from users. User input is solicited on appending at least one nominated subcategory to the parent category, and a nominated subcategory is appended to the parent category upon satisfaction of a second condition. User input is solicited to reassign a user post from the parent category to at least one subcategory.
摘要:
Method and system for implementing a multiple writer single reader queue in a lock free and a contention free manner. The method includes receiving a plurality of payloads from a plurality of users, assigning each payload to a writer thread, creating a corresponding writer queue by each the writer threads, enqueuing queue entries into the writer queues maintained exclusively by the each of the writer threads and dequeuing sequentially the queue entries by a reader thread. Further, the method includes adding and removing one or more writer threads in real time. The system includes an electronic device for displaying a plurality of payloads. The system also includes a processor, a memory that stores instructions and a communication interface in electronic communication with the electronic device and the processor.

Techniques for creating and enabling access to a community-augmented map are provided. The techniques include uploading user-generated content about one or more locations on a map, processing the user-generated content about one or more locations on the map and storing the user-generated content about one or more locations on the map in an intelligent knowledgebase, applying one or more domain concepts from the intelligent knowledgebase to the user-generated content to infer one or more derivatives in connection with one or more locations in the map, and retrieving information of the one or more locations on the map from the intelligent knowledgebase to provide the map information as augmented metadata on the map.
