Title: Polarization Rotator with Frequency Shifting Phase Conjugate Mirror and Simplified Interferometric Output Coupler
Inventor: ROCKWELL DAVID A
IPC: G01B9/02
Filed: 1994-06-16
Abstract: An interferometer that is used with a frequency shifting phase conjugate mirror (PCM) (12), to produce a 90° polarization rotation, employs only two adjustable elements:  a specially shaped prism (16), and a beam deflector that is preferably a porro prism (40). The primary prism is shaped and oriented so that a linearally polarized input beam (4) is divided into ordinary (o) and extraordinary (e) subbeams (24,26). One of the subbeams (26) is refracted out of the prism along a controlled length path, and then returned back into the prism by the deflector. The second subbeam (24) is retained within the prism by total internal reflection, and directed onto a exit path (38) that coincides with the path of the first subbeam after its reentry into the prism. The recombined output beam (10) is directed into the PCM, from which it is reflected back into the prism for a reverse pass. The difference in path lengths between the o and a subbeams is selected to produce a net 90° polarization rotation after both passes.

Title: Data-driven autorating for use in data communications
Inventor: PATEL MAHENDRA
IPC: H04L27/00
Filed: 1994-08-03
Abstract: -12-Data-Driven Autorating for use in Data Communications Abstract In transmitting information over a cellular communications channel (200) to an opposite endpoint (300, 30), a modem's (100) autorating routine is "data-driven." In particular, when the amount of information to transmit to the opposite endpoint is low, the modem's data rate is low, e.g., 4800 bps, and the modem's ability to autorate upwards, i.e., fallforward, is disabled. However, when the amount of information to transmit to the opposite endpoint is high, the modem's ability to fallforward is enabled so that the modem's data rate can increase to the highest permissible data rate for the cellular channel in order to transmit large blocks of information.

Title: Knowledge base management system with enhanced explanation of derived information and of error objects
Inventor: MCGUINNESS DEBORAH L
IPC: G06F9/44
Filed: 1995-04-27
Abstract: A knowledge representation system which allows a user to utilize a description language to generate, maintain and access information in a knowledge base is disclosed.  The knowledge representation system includes an explanation subsystem which explains where the derived information that is stored for a particular object was obtained from. A first level explanation function will provide a user with an explanation of the immediate source of the pieces of derived information that are stored for an object in the knowledge base.  A complete explanation function provides a complete explanation by continuing to explain how the immediate source for each piece of the information itself received the information, until the source of the information is told information or the result of a rule firing.  The explanation subsystem also explains subsumption inferences, which explain why a particular concept or rule antecedent is satisfied by a particular object.  The explanation that is generated may be limited in a number of ways  in accordance with the needs of a user.   An error handling subsystem facilitates the detection of the source of real errors.  Upon the detection of a real error, an error object is preferably created for the inconsistent object and for every other object that is affected by the error.   The error objects, which may be printed out or explained,  store all of the information associated with the corresponding object at a time when the data structures include the error information.

Title: Method and apparatus for a region-based approach to coding a sequence of video images
Inventor: CHEN HOMER H
IPC: H04N7/30
Filed: 1995-08-25
Abstract: The present invention discloses a method and encoder for coding sequences of digital images for transmission or storage.  Frames in the sequence are segmented into multiple regions of arbitrary shape each of which has a corresponding motion vector relative to a previous decoded frame.  In a preferred embodiment, a hierarchical multi resolution motion estimation and segmentation technique, which segments the frame into multiple blocks and which assigns a best motion vector to each block is used. Blocks having the same or similar motion vector are then merged to form the arbitrarily-shaped regions.  The shape of each region is coded, and a decision is made to code additional image data of each region in one of three modes.  In a first inter-frame mode, a motion vector associated with a region is encoded.  In a second inter-frame mode, a prediction error for the region is also encoded.  In an intra-frame mode, the intensity of each picture element in the region is encoded.  A region interior coder with frequency domain region-zeroing and space domain region-enforcing operations is employed for effectively coding the interior image data of the arbitrarily-shaped regions.  The region interior coder uses an iterative technique based on the theory of successive projection onto convex sets (POCS) to find the best values for a group of selected transform coefficients.  The coded information, including the shape of the region, the choice of the mode, and the motion vector and/or the region's interior image data, may then be transmitted to a decoder where the image can be reconstructed.
