20140145828 | MANAGING A SPHERE OF WIRELESS TAGS - A method for managing a sphere of wireless tags, the method comprises programming, by a wireless reader, a group of wireless tags to belong to the sphere of wireless tags; sending by the wireless reader sphere beacons aimed to the wireless tags of the sphere; detecting a loss of a wireless tag of the sphere if the wireless tag did not respond to a predetermined number of sphere beacons; and responding to the detecting of the loss of the wireless tag. | 05-29-2014 |
20140145829 | WIRLESS TAG BASED COMMUNICATION, SYSTEM AND APPLICAITONS - A method for detecting a presence of a tagged item within a tagged enclosure, the method comprising performing distance measurements between at least one wireless tag of the tagged enclosure and the tagged item to determine the spatial relationship between the tagged enclosure and the tagged item. | 05-29-2014 |
20140145831 | HYBRID WIRLESS TAG BASED COMMUNICATION, SYSTEM AND APPLICAITONS - A method, comprising: receiving during a wideband reception period and by a wideband reception circuit of a first wireless transceiver a wideband ranging message; transmitting during a wideband transmission period and by a wideband transmission circuit of the first wireless transceiver a wideband ranging response message; receiving by a narrowband reception circuit of the first wireless transceiver received narrowband messages; and transmitting by a narrowband transmission circuit of the first wireless transceiver transmitted narrowband messages. | 05-29-2014 |
20140145881 | DISTANCE MEASUREMENTS USING A SINGLE WIRELESS READER - A method, comprising: generating or receiving information about multiple distance measurements of distances between the wireless tag and the wireless reader at different points of time; wherein the wireless reader is positioned at different locations in relation to the wireless reader at the different points of time; generating or receiving information about a spatial relationship between the different locations or receiving information indicative of the spatial; and determining the location of the wireless tag in response to the multiple range measurements and the spatial relationship between the different locations. | 05-29-2014 |
20140148195 | LOCATION MEASURMENTS USING A MESH OF WIRELESS TAGS - A method for determining a location of a group of wireless tags, the method may include receiving first information indicative of distances between each wireless tag of the group and between at least three other wireless tags of the group; tracking a first movement of a certain tag of the group of wireless tag in relation to other wireless tags of the group to provide first movement information; receiving, after the performing of the first movement, second information indicative of distances between each wireless tag of the group and between at least three other wireless tags of the group; and determining locations of the wireless tags of the group in response to the first information, second information and the first movement information. | 05-29-2014 |
20140148196 | LOCAITON DETERMINATION IN AN INDOOR SPACE - A method for locating a user within an indoor space, the method comprises: receiving by a computer, distance information about distances between multiple wireless tags that are positioned within the indoor space; wherein the distance information is obtained by the multiple wireless tags during a first type of distance estimation process that comprises wirelessly transmitting messages between the multiple wireless tags; determining locations of the wireless tags in the indoor space in response to the distance information and to calibration information indicative of an actual or estimated location of at least one wireless tag in the indoor space; receiving, from a user device, user device location information related to a location of the user device in relation to a sub-set of the wireless tags; determining a location of the user device within the indoor space in response to the user device location information and to locations of the wireless tags of the sub-set of wireless tags in the indoor space. | 05-29-2014 |
20150243158 | METHOD FOR FINDING OBJECTS - A method, that may include determining, by a wireless reader, at least one locations of at least one wireless tag; determining, by a mobile device, which wireless tag out of the at least one wireless tag is a viewable wireless tag that is within a field of view of a camera of the mobile device; wherein the mobile device is either coupled to the wireless reader or comprises the wireless reader; and providing, by the mobile device, for each viewable wireless tag, a viewable wireless tag indication that is indicative of a location of each viewable wireless tag. | 08-27-2015 |
20150362581 | ROTATION BASED ALIGNMENT OF A GROUP OF WIRELESS TAGS - A method for determining a location of a wireless tag, the method may include generating or receiving, by a tagged mobile device, an estimated location of another tag that communicates with the tagged mobile device; receiving or generating, by the tagged mobile device, multiple distance measurements that are obtained during different points of time; wherein the multiple distance measurements are obtained during a rotational movement of the tagged mobile device and represent distances between the tagged mobile device and the other tag; finding a certain angle of rotation of the mobile device that corresponds to a minimal distance measurement of the multiple distance measurements; and amending the estimated location of the other tag based upon the certain angle of rotation. | 12-17-2015 |
