Abstract: The present invention relates to a recording and reproducing
method and apparatus for an optical disk 1 of the phase
transition type that can be overwritten. According to this
invention, the capacity of repeated rewriting of the optical disk
1 is expanded by recording either non-inverted write data 11a
or inverted write data 11b at random. The deterioration due to
the repeated rewriting at a start point and an end point of the
recording is suppressed by recording a synchronizing signal before
the write data and/or dummy data after the write data by varying the
recording light intensity such that thermal stress is less likely to
occur. A record end position can be determined precisely by
detecting a stop pulse to stop recording.

Abstract: A laser tracking system (10) steers a beam of laser
energy which is dithered in two directions to scan the
surface of a moving object (12). A laser energy detector
(58) detects laser energy reflected from the target (12).
Reflected energy is filtered to distinguish dither
frequencies for signals in both directions, which signals are
independently analyzed to determine the location of the
target (12) in relation to the laser beam. A bias signal is
generated which causes the beam of laser energy to be steered
toward a surface radius to be steered toward a surface with
the largest compound curvature within the trackers' field-of-regard,
to the target (12), to the tracked location on-target,
or modified signals steer a portion of the beam to an
optimum track location on target while offsetting most of the
beam's energy to a second engagement location on target.
Also, a track testing system (12) is capable of monitoring a
laser beam focused on a missile and determining the effective
laser engagement on a spinning target.

Abstract: The present invention discloses a method for securely
adding a new end station to a local area network (LAN)
segmented into a number of virtual local area networks (VLANs).
The invention is applicable to various types of LANs such as
Ethernet and token ring. The LAN comprises an authentication
server (AS) which interacts with each new end station before
connection to a VLAN is allowed. The method involves the AS
administering a test to the new end station, which may involve
prompting the new end station for a password or asking it to
encrypt a given number using a secret algorithm known only to
the new end station and to the AS. The AS examines the results
of this test and determines whether the new end station is
permitted to join the VLAN. For added security, the new end
station can verify authenticity of the AS by administering a
test of its own, which may consist of prompting the AS for a
password of its own or asking it to encrypt a new number, the
new end station subsequently determining whether the AS is
indeed genuine before beginning to transmit any further
information. In this way, an end station cannot join a VLAN
without authentication by the AS and a legitimate end station
can verify whether the test it is asked to pass comes from a
legitimate source, thereby avoiding network security breaches.

be formed by sputter deposition or any other appropriate deposition technique, e.g.,
