Abstract: A method for integrating in real time at least one virtual object (41, 42, 43, 44) into a video stream generated by a user equipment (20) and representing a real environment (RE), comprising the steps of calculating (C3) the so-called “real” position, in the real environment (RE), of a representation of the at least one virtual object (41, 42, 43, 44) relative to a predetermined reference position corresponding, in the real environment (RE), to the position of the virtual marker (30) in the virtual environment (VE), of integrating (U2) the representation of the at least one virtual object (41, 42, 43, 44) in a video stream generated at the calculated real position, and of displaying (U3) of the video stream so that said representation appears in real time on the images of the video stream generated at the calculated real position.

Abstract: Ultra-Wideband (UWB) wireless technology transmits digital data as modulated coded impulses over a very wide frequency spectrum with very low power over a short distance. Accordingly, the inventors have established UWB devices which accommodate and adapt to inaccuracies, errors, or issues within the implemented electronics, hardware, firmware, and software. Beneficially, UWB receivers may accommodate offsets in absolute frequency between their frequency source and the transmitter, accommodate drift arising from phase locked loop and/or from relative clock frequency offsets of the remote transmitter and local receiver. UWB devices may also employ modulation coding schemes offering increased efficiency with respect to power, data bits per pulse transmitted, and enabled operation at higher output power whilst complying with regulatory emission requirements.

Abstract: Ultra-Wideband (UWB) wireless technology transmits digital data as modulated coded impulses over a very wide frequency spectrum with very low power over a short distance. To support extended operation, particularly with battery power sources, the inventors have established UWB devices which support wake-up from deep sleep modes when these devices exploit low frequency clock sources for ultra-low power consumption. Further, power consumption may be reduced by exploiting transistors or so-called compounded MOSFET structures whose effective gain and output resistance exceeds any single transistor irrespective of length or by employing biasless low power differential (exponential) transconductance stages within operational transconductance amplifiers in order to provide very high gain low power amplification stages. Further, the inventors have established voltage reference sources that consume very low current, a few nA, and ultra-low power low dropout regulators.

Abstract: Ultra-Wideband (UWB) technology is a wireless technology for the transmission of large amounts of digital data as modulated coded impulses over a very wide frequency spectrum with very low power over a short distance. However, to support their deployment in a wide range of applications it would be beneficial to provide solutions which: exploit multiple directive antennas oriented in different directions to ensure spatial filtering of undesired signals and increase signal strength; exploit dynamic configuration of the multi-pulse bundles employed to transmit the bits/symbols within the packets to enhance link quality of service; exploit dynamic configuration of the band or bands which the transmitter operates upon; and exploit antenna sub-systems providing omnidirectional radiation patterns with implementations offering filtering and balun functions with small footprint and low cost.
