| A vehicle optical wireless data communication system includes a plurality of light sources disposed at a structure where vehicles travel. Each of the light sources emits visible light to illuminate the building or structure. Each of the light sources emits optical signals indicative of a location of the respective light source. A sensor is disposed at a vehicle and is operable to sense optical signals emitted by the light sources when the vehicle is in the vicinity of the light sources. Responsive to sensing by the sensor of optical signals emitted by at least one of the light sources, the sensor generates an output to a processor disposed at the vehicle. The processor processes the output of the sensor to determine a location of the vehicle relative to at least one of the light sources. | ||||||

| 230 | Method and device for improving configuration of communication devices in a video projection system comprising multiple wireless video projectors | US13828749 | 2013-03-14 | US09686516B2 | 2017-06-20 | Lionel Tocze; Pierre Visa; Pascal Lagrange |
| The present invention relates to improving configuration of wireless communication paths between devices in a video projection system comprising multiple wireless video projectors. When an initial radio communication setup is required between a managing node, e.g. a node comprising a master projector, and a node comprising a slave projector, for example following the powering up of the video projection system, the slave node receives setup information by radio communication means according to a sweeping sequence and transmits information by projecting sub-images. Sub-images advantageously comprise information relative to settings of the master node allowing reception in the corresponding slave node of a radio signal transmitted by the master node. | ||||||
| 231 | METHOD AND SYSTEM FOR DYNAMIC REASSIGNMENT OF AN IDENTIFICATION CODE IN A LIGHT-BASED POSITIONING SYSTEM | US15332410 | 2016-10-24 | US20170139033A1 | 2017-05-18 | Stephen H. Lydecker; Konstantin Klitenik; Daniel Ryan; Emanuel Paul Malandrakis; Mitri J. Abou-Rizk |
| In a visual light communication (VLC) or other light based positioning system, a mobile device can detect modulated light emitted by one or more localized artificial lighting devices to obtain an identification (ID) label or code of each lighting device, e.g. that is visible in an image captured by the mobile device camera. The mobile device uses the detected ID code for a lookup in a self-stored or remotely stored table that associates light-source-location information with ID codes, to obtain an estimate of mobile device position. To mitigate against hacking by a third party detecting the ID codes and observing locations to compile its own lookup table, the disclosed examples dynamically alter the assignments of particular ID codes to the lighting devices, while minimizing potential disruption of position determination service for mobile devices due to the changes to ID code assignments. | ||||||

| Disclosed are various approaches for navigation identifying one's current position. A navigation device receives a guided surface wave using a guided surface wave receive structure. The navigation device then receives a reflection of the guided surface wave using the guided surface wave receive structure. The navigation device calculates an amount of time elapsed between receiving the guided surface wave and receiving the reflection of guided surface wave. The navigation device then measures an angle between a wave front of the guided surface wave and a polar axis of the Earth. Finally the navigation device determines a location of the guided surface wave receive structure based at least in part on the angle between the wave front of the guided surface wave and the polar axis of the Earth the amount of time elapsed between receiving the guided surface wave and receiving the reflection of guided surface wave. | ||||||
