Abstract: The invention relates to a method and a device for grouping into batches fragile buoyant objects, such as buoyant fruit, in at least one accumulation channel with hydraulic superposition of the objects held in a superposition zone against a closed holding/releasing device so as to hold the objects. During a step of accumulating objects in an accumulation channel (11), an elevation (17) extending upwards from the bottom (19) of the accumulation channel (11) is moved upstream in said superposition zone (18) from the downstream end (13) of the accumulation channel (11) as the objects are being supplied so as to cause a superposition of the objects held in the superposition zone between said elevation (17) and the holding/releasing device (14).

Abstract: The invention is a method of configuring a device and a wireless unit. The device is able to operate in tag mode and in wireless reader mode. The wireless unit is able to operate in wireless reader mode and in a card emulation mode. The method comprises the steps of: reading a setting data into the device running in tag mode, the setting data corresponding to a first configuration and being read by the wireless unit which operates in wireless reader mode, activating the first configuration in the unit, writing an acknowledgment data into the device and switching the unit to the card emulation mode, switching the device to the wireless reader mode when the presence of the acknowledgment data is detected in the device.

Abstract: In order to send electromagnetic signals received on one or more first frequency bands, the method applies a transformation to the signals, by performing the following actions: selecting first frequency subbands, forming a first set of frequency subbands of the first frequency band(s); using organization rules to associate one or more second sets of frequency subbands, forming one or more second frequency bands, with each first frequency subband of the first set; and using optimization rules to determine frequency translations to transpose the signals received in the first frequency subbands into signals sent in the second frequency band(s).

Abstract: The invention relates to a wireless system for transmitting data between a base station and a relay antenna of a mobile telephony network. A link comprises, for the separating of the channels, two filters having a lower isolation than a total predetermined isolation and the antennas are dual-polarization antennas, each polarization being allocated to one of the two channels. The isolation provided by the filters and the antenna are added together to obtain the total predetermined isolation.

Abstract: A method of synchronizing two electronic devices connected by a wireless link with at least one path including a transmission channel and a reception channel. The two devices are included in a network, such as a mobile telephone network. Synchronization information is transmitted directly from one electronic device to the other, as a clock pilot signal, via the channels. After recovery, the clock pilot signal is used for synchronization of a reference frequency of the receiving electronic device.
