The tilted optical receiver is mounted on a rotatable platform and thus, various azimuth angles can be obtained by rotating the platform, which offers a feasible way to perform multiple measurements with different azimuth angles to achieve the angle gain. 2012-11-20Assigned to SEMTECH CANADA INC. CORRECTIVE ASSIGNMENT TO CORRECT THE ERROR PREVIOUSLY RECORDED ON REEL 028333 FRAME 0287. Assignors: GENNUM. Conventional visible light positioning (VLP) systems usually require at least three light-emitting diodes (LEDs) to enable trilateration or triangulation, which is infeasible when the LED condition is constrained. 3V or 5V DC power supply The Firecomms DC to 10 MBd transmitter incorporates a highly reliable resonant cavity light emitting diode (RCLED) and an integrated driver IC, and is housed in a miniature package to interface. Optical Engineering is an SPIE journal that publishes peer-reviewed articles reporting on research, development, and applications of optics and photonics. However, unfortunately, few algorithms can be applied to the case that the receiver is tilted.
