A case for an electronic device has a hollow body which forms at least one receiving housing for an electronic device (E) and has an access opening to the housing surrounded by a peripheral edge outside the housing which has a truncated conical or truncated pyramidal shape converging on the opening. The case further includes a cover for closing the housing which has a peripheral flange. The inner peripheral face has a truncated conical or truncated pyramidal shape complementary to the shape of the peripheral edge of the opening of the case, the flange of the cover being designed to fit onto the peripheral edge of the opening and be held there by adhesion.

The invention relates to a system for determining surroundings in a wireless network, the system including first and second nodes, each node being programmed to periodically detect the nodes located in the surroundings thereof every time period &#x394;, characterized in that: the first node comprises a transmitter () and control means () for activating the transmitter () for a transmission time &#x3be; less than the time period &#x394;, the transmitter transmitting an identification signal during the transmission time &#x3be;; the second node comprises a receiver () and control means () for activating the receiver () for a reception time &#x3b1; less than the time period &#x394;, the receiver () listening for the signals from the adjacent nodes during the reception time a, the control means () of the second node activating the receiver once per time period &#x394;.

A data processing device includes a memory, a direct memory access controller including a receiving module configured to receive data coming from outside the device and for writing the data in a main buffer memory of the memory, and a processing unit programmed to read and process data written by the receiving module in a work area of the main buffer memory. The main buffer memory is divided between a used space, where the receiving module is configured not to write, and free space, where the receiving module is configured to write. The processing unit is further programmed to define the work area, and the direct memory access controller includes a buffer memory manager configured to free data written in the main buffer memory, by defining a location of this data as a free space, only when this data is outside the work area.
