Granted: 1999-08-24
Abstract: A method and system (50) for tracking the position of a moving transmitter using angle of arrival measurements from direction finding antenna arrays (60, 70).  Each array includes several  elements  (60A-60N,  70A-70N),  with the elements grouped to provide subarrays of different element spacings which are multiple of one half the transmitter wavelength.  Ambiguity is rejected by processing angle data received from the subarrays.  The signals from the arrays are  processed  to  convert  electrical  phase  delay  into spatial angles,  the spatial angle data is processed to provide the x,y position, velocity and acceleration of the transmitter.  For transmitters mounted in moving vehicles, the system further processes the x,y data and applies a quality weighting factor that filters out multipath factors and permits estimation of vehicle profile information.

Granted: 2000-10-24
Abstract: A telephone line interface section, which has   a selector  switch for selectively connecting two of  a facsimile section, a telephone line and an information unit such as a personal computer,  is provided.   The telephone  line  interface  section is provided with a telephone line monitor which detects an ON/OFF state of a start switch for directing the facsimile section to be operated and detects existence or non-existence of a DC loop current which is a connecting signal at the time when the facsimile section is connected to an external telephone  switchboard via  the  telephone  line.    The selector switch connects the facsimile section to the information unit based upon the telephone line monitor when  the  start  switch  is  in  the  ON  state  and  the connecting signal is not detected.  As a result, in the case where the facsimile section is used as a scanner and printer of the information unit, the facsimile section can be simply connected to the information unit.

Abstract: Antenne à double hélice (10) composée de deux conducteurs hélicoïdaux enroulés de façon orthogonale. Cette antenne (10) comprend un premier conducteur hélicoïdal (14) enroulé dans un premier sens autour d'un axe vertical, V, de l'antenne (10). Un deuxième conducteur hélicoïdal (18) est enroulé dans un deuxième sens autour de l'axe vertical V. Dans un mode de réalisation spécifique, les premier et deuxième conducteurs hélicoïdaux (14 et 18) possèdent des longueurs différentes, correspondant respectivement à une première et à une deuxième bande de fréquence. De plus, les premier et deuxième conducteurs hélicoïdaux (14 et 18) sont enroulés de manière à se trouver en position orthogonale par rapport aux plans horizontaux à l'intérieur desquels lesdits premier et deuxième conducteurs hélicoïdaux (14 et 18) viennent en intersection ou, sinon, sont séparés par un espace minimum à l'horizontale. Ce rapport d'enroulement orthogonal entre les conducteurs hélicoïdaux limite considérablement le couplage réciproque, ce qui permet à des antennes hélicoïdales séparées de fonctionner à proximité étroite les unes des autres.

Abstract: An arrangement to protect software, particularly freely distributed application software, against utilization without permission of the copyright holder. By encrypting the software employing a key (k1) which is different from that key (k2) which is employed in the decryption, better protection is obtained against unauthorized utilization when the decryption key is kept secret to the user. Further improved security is achieved by additionally executing scrambling-descrambling of the communication between the computer in which the software is utilized and the external unit in which the decryption key is stored. Also, the external unit is arranged such that it returns to the host computer, the result from its processing of data received from the host, the result then being utilized in the further execution of the respective program.
