A particular implementation selects two or more fiducial markers to be embedded into a video to convey information. Specifically, the translation, scaling and rotation between a reference marker and a secondary marker can be used to transmit information. When more information needs to be embedded, more secondary markers can be used. The transformation between the fiducial markers can also evolve over time as the information to be embedded evolves over time. At the receiving side, a reader device captures a video including multiple fiducial markers and determines the translation, scaling and rotation between the fiducial markers. Based on the transformation of the fiducial markers, the reader device can retrieve the information embedded in the captured video by the fiducial markers.

Method and system for embedding and retrieving information through marker transformation

The invention relates to a method of transmitting time information relating to the clock of the source of a sending part consisting in using a fixed latency indicator signal to authorize the source to insert time information used to slave the clock of the decoder of the associated receiving part to its clock.

Method of transmitting time information with fixed latency

The invention relates to an antenna system comprising a first type of antenna and second and third antennas of a second type. The first to third antennas are slots which are excited by longitudinal radiation and are placed on the same edge of the same substrate. The first antenna is placed between the second and third antennas. This system is particularly suitable for integration in a PCMCIA card.

Radiating slit antenna system

The present invention relates to a radiation diversity antenna consisting of radiating elements of the slot-line type coupled electromagnetically to a feed line, in which the radiating elements have a tree structure, each radiating element having a length equal to k&#x3bb;s/2 where k is an identical or different integer from one element to the next and &#x3bb;s is the guided wavelength in the slot-line constituting the radiating element with at least one radiating element comprising a switching means positioned in the slot-line constituting the said radiating element in such a way as to control the coupling between the said radiating element and the feed line as a function of a command. The invention applies chiefly to wireless transmissions.

The present invention relates to a planar antenna carried by a substrate including a slot ( ) consisting of a closed curve dimensioned in order to operate at a given frequency and fed by a feed line ( ) positioned so that the slot lies in a short-circuit plane of the feed line. This antenna includes, in parallel on the slot , at least one switching means capable of assuming a closed state or an open state so as to modify the operating frequency band of the planar antenna. This antenna is particularly suitable for domestic wireless networks.

Planar antennas of the slot type

The invention relates to a dielectric resonator oscillator, comprising a dielectric resonator contained in a resonant cavity in order to generate a signal oscillating at a predetermined central frequency, the dimensions of the resonator and the limiting conditions in the cavity being capable of determining the resonant frequency of the resonator. It comprises means sensitive to acoustic pressure waves capable of modifying the distribution of the electromagnetic fields in the cavity as a function of said acoustic pressure waves. The invention also relates to a voice control device equipped with an oscillator according to the invention. Particular application to remote voice control devices for controlling domestic equipment.
