A device associates an enclosing capsule in which will be fitted electronic equipment requiring dehumidification, and a medium-to-low voltage converter to recharge electronic equipment. Heat energy released by the coil in the converter will lead to a free thermal exchange of air between the inside and the outside of the capsule, produced by the natural convection from vent holes located in the lower part of the device through which air will be sucked from the outside and vent holes located in the upper part of the device through which warm air thus produced will escape. The circulation of unsaturated warm air around the electronic equipment has the effect of removing the water molecules on the components by saturating the ambient air in the confinement zone, this air being evacuated through vent holes located in the upper part of the device.

Dehumidifying device for rechargeable electronic equipment

The method for programming recordings is applied to a recorder device containing a videogram medium and connected to a programming terminal equipment unit located in an area covered by one or more radio cells of a cellular radiotelephony network. The terminal equipment has receiving and reading means capable of receiving text messages transmitted over a broadcast channel of the network and reading concatenation sequences contained in the messages, each containing information data of a programme item from a programme broadcaster. The user selects on an input interface of the recorder device, a type of programme to be recorded which is transformed with a determined format into a recording code, which code is compared with at least one portion of each of the sequences so as to use the recording data and automatically parameterize the recording.
