Abstract: PURPOSE: A method for estimating a weight in a communication system using a smart antenna is provided to reduce the convergence speed of an algorithm by making a gradient using an autocorrelation matrix akin to a true gradient by estimating the autocorrelation matrix to have Hermitian and Toeplitz characteristics. CONSTITUTION: It is assumed that an initial weight vector is w(0)(S10). It is assumed that a newly received signal vector is x(k)(S11). The received signal vector x(k) is separated into x_s(k)(=As(k)) and x_v(k)(=v(k))(S12). Autocorrelation matrices are obtained by using the separated x_s(k)(=As(k)) and x_v(k)(=v(k))(S13). A gradient g(k) is calculated to maximize an SINR(Signal Interference Noise Ratio) of a result signal y(k)(S14). A coefficient A of x_s(k)(=As(k)) is estimated by using a pilot channel in a CDMA system(S15).

Abstract: A vehicle is subjected to many requirements and wishes. One of these is that the vehicle is to protect passengers and load during a collision. This is achieved in that different parts in and on the vehicle are designed and constructed such that they, in different ways, absorb, distribute and channel energy during a collision. A bumper bar for a vehicle must be deformed both elastically and/or plastically during a collision. This invention offers a bumper bar that in its basic construction provides these properties. The invention concerns a bumper bar for vehicles where the bar is extended and has a closed cross-section with at least one forward flange (1) facing forwards in the normal direction of motion of the vehicle, an upper web (3) and a lower web (4). The forward flange (1) of the bumper bar is provided with elastically deformable grooves (6).

Abstract: PURPOSE: A circuit for sensing an error of a communication line is provided to indicate the error of the communication line by using a display or an LED. CONSTITUTION: A first monostable multivibrator(220) is used for receiving a data signal and outputting a low level signal if a falling edge is not detected from the data signal within a predetermined time. A first display(224) is turned on or off by an output signal of the first monostable multivibrator. A second monostable multivibrator(230) is used for receiving a clock signal and outputting a low level signal if a falling edge is not detected from the clock signal within a predetermined time. A second display(234) is turned on or off by an output signal of the second monostable multivibrator.
