This system accompanies the alarms of TAWS type and in particular the alarms of “Avoid terrain” type indicating to the pilot that he has passed the limit point of success of a standard vertical avoidance maneuver, indications (32, 33) of free-travel distances in azimuth sectors suited to a clearance maneuver and one or more recommended relief avoidance maneuvers (A, B), both lateral and vertical. For the determination of the limit point, it monitors the penetration of a model of the terrain being flown over into a first protection volume (1) linked to the aircraft and configured in such a way as to model a standard vertical avoidance maneuver trajectory executed without notable delay. For the determination of the azimuth sectors open to a clearance maneuver, it analyzes the penetrations of the model of terrain being flown over in a second protection volume with large azimuth aperture, linked to the aircraft and configured in such a way as to contain the limit point protection volume (1). To evaluate the free-travel distances, it searches for limit points of effectiveness of a standard vertical avoidance maneuver, on arbitrary distancing trajectories in the azimuth sectors open to the clearance maneuvers. Based on the determination of these free-travel distances, the system determines the limit instant of manual initiation by the pilot or automatic initiation of an avoidance trajectory and determines the optimum route alteration to be initiated prior to the avoidance maneuver.

A method and apparatus is provided for automatically classifying a defect on the surface of a semiconductor wafer into one of, e.g., seven core classes: a missing pattern on the surface, an extra pattern on the surface, a deformed pattern on the surface, a particle on the surface, a particle embedded in the surface, a particle and a deformed pattern on the surface, or craters and microscratches on the surface.

Thus, defects are accurately and reliably classified and monitored to enable early detection and cure of processing problems.

Embodiments of the invention relate to beamforming antennas such as can be used in space division multiplexing systems. Space division multiplexing can be used to increase data capacity in wireless networks by enabling different base stations to transmit signals within the same frequency band. Each antenna beam can potentially be used to establish a communication link within an area of wireless coverage, and other communication links established on other antenna beams then represent interference to that user. In order to reduce interference, narrow beamwidths are desirable. These are typically achieved by increasing the aperture of the antenna in the azimuth plane, and in arrangements that require finely divided angular sectors, a greater number of antennas will be required to give three hundred and sixty degree coverage. As a result, there is potentially a large increase in the total surface area of antennas which is undesirable, as it leads to increased wind loading of an antenna tower. Embodiments of the invention provide an arrangement in which data are transmitted from a first transmitter to a first receiver using a first antenna beam, and data are transmitted from a second transmitter to a second receiver using a second antenna beam. The first antenna beam is formed by splitting the signal from the first transmitter into two parts with a first phase relationship between the parts, each part being connected to an antenna. A second antenna beam is formed by splitting the signal from the second transmitter into two parts with a second phase relationship between the parts, each part being connected to one of the two antennas. An advantage of embodiments of the invention is that data can be transmitted from different transmitters at the same frequency without interference, while presenting a smaller antenna aperture than is required with conventional systems.
