| 20080281787 | Content storing device query - A method, apparatus, and correspondingly configured computer program, in which a querying device inputs a user an identification of desired content and sends a query request for the desired content to surrounding memory devices. The query request is adapted to cause compatible receiving memory devices to perform a search based on the request. The memory devices are configured to listen to query requests and responsively perform searches based on the queries. Any memory device that finds content according to the query request responds to the query device which, after sending the query request, monitors for the compatible receiving memory devices for information that the queried content is found. Responsive to receiving the information from a given memory device, the querying device establishes a connection with the given memory device and obtains the content. | 11-13-2008 |
| 20080301301 | Information sharing in a smart space - An apparatus and method for storing and maintaining in a smart space device connectivity information of devices of the smart space including a plurality of disparate radio access technologies. The connectivity information is propagated to at least one other device of the smart space and is used for selecting an optimal distribution route for information to be shared in the smart space. Technologies such as NoTA, BillBoard and Whiteboard can be used. | 12-04-2008 |
| 20090146791 | Method, device, and system for "listen-before-talk" measurement to enable identifying of one or more unoccupied RF sub-bands - The invention relates to a method of performing a Listen-Before-Talk measurement to enable identifying of one or more unoccupied radio frequency sub-bands applicable for radio frequency identification (RFID) communication operable with a radio frequency identification (RFID) reader subsystem; said method including obtaining timing information relating to one or more periods of activity of a wireless communication subsystem; deriving information about one or more periods of non-activity from said timing information; configuring said wireless communication subsystem to perform said Listen-Before-Talk measurement in coordination with said one or more periods of non-activity; and performing said Listen-Before-Talk measurement by the means of the wireless communication subsystem to identify said one or more unoccupied radio frequency sub-bands. | 06-11-2009 |
| 20090179628 | Detection of lightning - A lightning detector for lightning detection and a lightning detection method, wherein the lightning detector uses at least two separate channels or frequency bands for lightning detection, and wherein the lightning detector is a mobile RF device provided with radio interfaces for at least two communication channels or frequency bands, whereby at least one of which is normally a telecom channel/frequency range and wherein these channels/ranges are used in lightning detection. | 07-16-2009 |
| 20100085257 | SYSTEM AND METHODS FOR DIRECTION FINDING USING A HANDHELD DEVICE - A system for indicating the relative direction of a target object or location as determined from the current position of a wireless communication device. The system employs Direction of Arrival determination using an antenna array for indicating the direction of a target device and includes facilities to activate a location-indicating transmission in a target device, the ability to request that a location-indicating transmission be activated in a remote target device, relevant information reception from a target device and the display of all potential target devices within effective transmission range of the wireless communication device. | 04-08-2010 |
| 20100285849 | Method and Apparatus For Staged Approach Transient RF Detection And Sensor Power Saving - A method includes receiving a first signal from an antenna of a device and at least one internal device signal in a low-energy consumption path, detecting a peak in at least one of the first signal and the at least one internal device signal, and activating a higher energy consumption path to analyze the first signal when the detected peak is not in one of the at least one internal device signal. | 11-11-2010 |
| 20100309058 | SYSTEM AND METHODS FOR DIRECTION FINDING USING A HANDHELD DEVICE - A system for indicating the relative direction of a target object or location as determined from the current position of a wireless communication device. The system employs Direction of Arrival determination using an antenna array for indicating the direction of a target device and includes facilities to activate a location-indicating transmission in a target device, the ability to request that a location-indicating transmission be activated in a remote target device, relevant information reception from a target device and the display of all potential target devices within effective transmission range of the wireless communication device. | 12-09-2010 |
| 20100315289 | DISTANCE ESTIMATION - The invention relates to an apparatus and method for estimating the distance between a transmitter and a receiver. A method comprising obtaining a signal from a receiver; determining whether the signal more likely propagated through a line-of-sight (LOS) radio channel or a non lme-of-sight (NLOS) radio channel; using a model including parameters selected according to the radio channel to estimate the distance between the receiver and a transmitter which sent the signal. | 12-16-2010 |
| 20110119486 | METHOD AND APPARATUS FOR MANAGING ACCESS RIGHTS TO INFORMATION SPACES - An approach is provided for managing access rights of users to information spaces using signatures stored in a memory tag. A signature manager caused reading of a memory tag to initiate a request, from a device, for an initial access to an information space. The request includes an authorization signature associated with the device. The signature manager determines a level of access to the information space by comparing the authorization signature against a lattice of signature primitives associated with the information space. The signature manager then modifies the authorization signature based on the determination and stores the modified authorization signature for validation of subsequent access to the information space by the device. | 05-19-2011 |
