The present invention increases the aperture size of a microphone array by introducing a diffracting structure into the interior of a microphone array. The diffracting structure within the array modifies both the amplitude and phase of the acoustic signal reaching the microphones. The diffracting structure increases acoustic shadowing along with the signal's travel time around the structure. The diffracting structure in the array effectively increases the aperture size of the array and thereby increases the directivity of the array. Constructing the surface of the diffracting structure such that surface waves can form over the surface further increases the travel time and modifies the amplitude of the acoustical signal thereby allowing a larger effective aperture for the array.

The invention relates to a pressure self power generating-charging module of a pure electric driving vehicle. A pressure power generating material or the principle that an electromagnetic coil cuts magnetic lines to generate power is employed to produce the module. The module is arranged on a suspension part between each tire and a chassis of the vehicle. In a running process of the vehicle, the vehicle weight pressure and the produced up and down vibration on the road enable a piezoelectric module or an electromagnetic power generating module to constantly generate power, so that a power driving battery is constantly charged and the electric power consumed in the running of the power driving battery is supplemented. As long as the vehicle starts running, the power generating module starts power generating and charging. If the power generating efficiency and the power generating technology of the power generating module are constantly improved, the consumption of the electric power of the battery of the pure electric driving vehicle in the running process is greatly slowed down, and the number of charging and the charging time are reduced. In order to prevent the module from being damaged by the too large pressure of the vehicle in the running process of the vehicle, a damping and buffering spring and a position limiting protection connecting mechanism are arranged between the module, the chassis and a cross beam. The module can be applied in all pure electric vehicles including rail trains and subway trains at home and abroad.

Techniques for sending routing data include sending first routing data in a first multicast packet to a number N of adjacent nodes. It is determined whether different routing data is ready to be sent in a different multicast packet. If so, then a number M of adjacent nodes from which acknowledgment messages have been received, and whether M exceeds a threshold, is determined. If so, then a Conditional-Receive (CR) method is invoked in which a multicast message is sent which identifies each of a number L=N−M of laggard adjacent nodes. The laggard adjacent nodes are thus notified to ignore the different multicast packet. If it is determined that M does not exceed the threshold, then additional acknowledgement messages are received while waiting until M does exceed the threshold before the CR method is invoked. The threshold is greater than or equal to 1.
