Title: System and method for minimizing nonlinear distortion in optical communication systems employing laser intensity modulation
Inventor: RAINAL ATTILIO JOSEPH
IPC: H01S5/06
Filed: 1996-01-09
Abstract: An amplitude limiting circuit is utilized to select the most favorable linear region of the light vs. current characteristic curve (for directly modulated lasers) or the lasers modulator transfer function (for externally modulated lasers) by preventing excursions of the broadband, multiplexed input signal beyond selected upper and lower current or voltage limits. The clipped broadband signal is represented as a stationary Gaussian process to provide a reliable estimate of the carrier-to-nonlinear distortion per channel that would be experienced with a given laser or optical modulator. The distortion control technique of the present invention is equally applicable for both directly and externally modulated lasers. In a directly modulated system, for example, an amplitude limiter may be used to clip the multiplexed signal to prevent excursions below the threshold and/or above saturation and thereby avoid the unpredictable levels of nonlinear distortion associated therewith. Instead, the clipping levels can be set to achieve an acceptably low level of non-linear distortion.

IPC: E03F3/04
Filed: 1996-01-26
Abstract: A method of jointing members and a jointing structure capable of simplifying the jointing operation and facilitating jointing of members firmly without exposing jointed portions on jointing surfaces of the members. A recessed portion is formed in the jointing surface of one member and a bag body made of a flexible material is attached to the jointing surface of the other member wherein the jointing surfaces of both members are brought into contact with each other while the bag body is inserted into the recessed portion and a filler is introduced into and fills the bag body so as to expand the bag body into a shape corresponding to the inner peripheral shape of the recessed portion. Tensile strength is generated in the bag body that has been expanded by the fillers in the jointing direction, whereby both members can be firmly jointed with each other while they are fastened by the filled bag body. Concave and convex portions or stages are provided on the jointing surfaces, thereby resisting a shearing force.

Title: Method and circuit arrangement for forwarding message cells transmitted via an atm communication equipment to a serving trunk
Inventor: RIEDEL MICHAEL
IPC: H04L49/111
Filed: 1996-03-01
Abstract: During the course of virtual connections, message cells are transmitted via the ATM communication equipment  (KE)  working according to an asynchronous transfer mode and are forwarded to a serving  trunk  (A1,...,An)  coming  into  consideration  for  the respective  virtual  connection.     Characteristic  parameters corresponding to the traffic characteristic of the message cell stream to be transmitted are thereby determined for the respective virtual connection during the course of the call setup.  Based on the criterion of these characteristic parameters, a time interval for the forwarding of a message cell to the serving trunk coming into consideration is determined for every message cell transmitted via the ATM communication equipment.  It is thereby provided that the  time  interval  for  the  respective  message  cell  is  only determined with the forwarding of a message cell of the same virtual connection that immediately precedes it.

Title: Processing for mode-s signals suffering multipath distortion
Inventor: SCHWAB CARL E
IPC: H04B7/08
Filed: 1996-03-29
Abstract: A communication system for receiving aircraft reply squits (transmissions) normally used in a radar beacon system for surveilling aircraft in a given geographic area.  The communication system includes a plurality of omnidirectional receivers, each receiver having a function of omnidirectionally receiving the aircraft squits and developing therefrom two types of information strings, namely a data string, indicative of a message in the aircraft squit, and a corresponding confidence string indicative of the reliability of the developed data string.  A data communication link transmits the data and confidence strings between the plurality of omnidirectional receivers and the master data processor. The  master data processor processes the data strings and corresponding confidence strings developed by each of the plurality of omnidirectional receivers by performing a bit-by-bit comparison of the received data strings and corresponding confidence strings, so as to develop by the comparison a corrected data string which minimizes the use of data bits from the data strings received over the data communication link that are indicated by the corresponding confidence strings as having a low reliability.

Title: Video image colour encoding
Inventor: PENNA DAVID EDWARD
IPC: H04N11/04
Filed: 1996-01-26
Abstract: A method is described of encoding pixel colour values for a digital video image frame in which each different colour within the image is assigned a colour value. A predominant colour is identified for the image frame and, in a first embodiment, each pixel having a colour other than the predominant colour is separately coded as its respective colour value (0010 to 1111), with runs of three or more successive pixels of the predominant colour being run-length encoded. A further code (0000 0011 cccc), similar in arrangement to that indicating a run, is provided to allow a change in the specified predominant colour during the course of a frame. In a further embodiment, runs of all colours are run-length encoded but with a shorter coding scheme for runs of the predominant colour or, in a still further embodiment, a small range of predominant colours. A principle use for these coding schemes is to improve efficiency of coding for certain classes of image material.

Title: Vehicle article carrier
Inventor: CUCHERAN JOHN S
IPC: B60R9/045
Filed: 1996-12-06
Abstract: A vehicle article carrier having a pair of side rails and at least one adjustable cross bar.  The adjustable cross bar includes a pair of bracket members at its outermost ends which are adjustably positionable along the side rails.  Each bracket member  includes  a rotator having a circumferential  camming surface which is in contact with a head portion of a locking member.  When the rotator is rotated in a first direction, the camming  surface  urges  the  locking  member  out  of  clamping engagement with its associated side rail.  When the rotator is urged rotationally in the opposite direction, a biasing member is allowed to urge the locking member into clamping engagement with the associated side rail.  In a preferred embodiment, the locking member includes a pair of raised surfaces which cooperate with notches formed in overhanging ledge portions of a channel of the associated side rail to allow the locking member to be positively engaged with the side rail when the rotator is in the locked position.   The rotator has the desirable feature of remaining substantially flush with the outer surface of its associated bracket member regardless if it is in its locked or unlocked positions.

Title: Hybrid single sideband optical modulator
Inventor: CONRADI JAN
IPC: H04L27/04
Filed: 1997-02-14
Abstract: Bandwidth reduction methods and apparatus that offset the effects of dispersion on a signal transmitted through an optical fiber. The apparatus and methods employ a generator of modulated optical signals in cascade with a modulator. One of the generator and the modulator may be an optical intensity or amplitude modulator and the other a phase (or frequency) modulator.  With the application of specific  signals,  the cascaded generator and modulator produce an optical signal with reduced energy in one half of the transmission bandwidth. One important benefit in the method is the fact that by exploiting the less obvious spectral  characteristics of  single sideband signals,  a simple modulator design is achieved. All of the designs exploit a method of generating analytic signals via hybrid modulation.
