摘要:
The invention relates to a fall detection system, for detecting human fall incidents. The detection system comprises a sensor module to be worn by a user, for collecting motion data of his body, for instance acceleration data; first evaluation logic for identifying a potential fall incident on the basis of an impact observed in the acceleration data; and second evaluation logic for verifying that the sensor module is actually worn by the user, at least around the time of said impact, to prevent the system from raising an alarm if only the sensor module has fallen. The second evaluation logic may comprise free fall detection means for evaluating the acceleration data on characteristics which are typical for a free falling object, such as one or more full rotation and/or a free falling phase, during which the magnitude of the acceleration data is relatively stable and small. Additionally or alternatively the second evaluation logic may comprise body proximity detection means for detecting whether the sensor module is in close proximity to the human body.

A system 100 includes a rendering apparatus 120, a server 110 and a network 130. Content items on the server are identified by respective server content locators, such as a URL. The rendering apparatus also has access to local content. Titles of the local content are associated with respective local content identifiers, such as title IDs. The system can generate and store a plurality of bookmarks, that each include a server content locator and a local content identifier. The rendering apparatus can render items of the local content and server content items that relate to the local content items. The rendering apparatus renders a server content item indicated by the server content locator of a bookmark conditional on having access to a local content title associated with the local content identifier of the bookmark.

The invention relates to a method of presenting media content to a user or group of users, wherein the media content resides on a storage system and the method comprises the steps of defining a query to retrieve the media content, which query is appropriate for the user's situation by using context information; retrieve the queried media content from the storage system; and presenting the queried media content to the user or group of users.

The present invention reuses an accelerometer, or, more precise, sensed accelerations of a body sensor for user control of the body sensor. This is achieved by detecting predefined patterns in the acceleration signals that are unrelated to other movements of the patient. These include tapping on/with the sensor, shaking, and turning the sensor. New procedures are described that make it possible to re-use the acceleration sensing for reliable gesture detection without introducing many false positives due to non-gesture movements like respiration, heart beat, walking, etc.

The invention relates to a method of retrieving a plurality of information items from a data storage, the method comprising: submitting a request to the data storage, the request comprising a general classification; retrieving the plurality of information items of which at least a predefined amount of the plurality of information items complies with the general classification and wherein the general classification defines a first class and the plurality of information items are elements of a second class and there exists a subsumption relation between the first and second class. The invention further relates to a system (300) for retrieving a plurality of information items from a data storage, the system comprising: submitting means (306) conceived to submit a request to the data storage, the request comprising a general classification; classification means (312) conceived to define a first class and a second class, wherein the general classification defines the first class, and wherein the plurality of information items are elements of the second class and there exists a subsumption relation between the first and second class; retrieving means (308) conceived to retrieve the plurality of information items of which at least a predefined amount of the plurality of information items complies with the general classification.
摘要:
This invention relates to a device and a method of generating a first and a second fingerprint (102,104) usable for synchronization of at least two signals (101,103) and corresponding method and device for synchronizing two or more signals. A fingerprint pair is generated on the basis of a segment of a first signal e.g. an audio signal and of a segment of a second signal e.g. a video signal at each synchronization time point. The generated fingerprint pair(s) are stored in a database (203) and communicated or distributed to a synchronization device (303). During synchronization, fingerprint(s) of the audio signal and fingerprint(s) of the video signal to be synchronized are generated and matched against fingerprints in the database. When a match is found, the fingerprints also determine the synchronization time point, which is used to synchronize the two signals. In this way, a simple, reliable and efficient way of synchronizing at least two signals is obtained. Further, this is enabled without modifying either the first and second signal (or subsequent signals). The signals may even be distorted or changed to some extent while still enabling synchronization.

The navigation support through interaction fields in XML documents such as XHTML and SMIL is supported by the so-called tabindex attribute. In order to enable two dimensional navigation through the interaction fields, a method is proposed that divides the interaction fields into a plurality of sub-sets. Navigation according to one dimension navigates through the interaction fields across the plurality of sub-sets. Navigation according to the other dimension navigates through the interaction fields within a plurality of sub-sets.
