Title: Method and apparatus for connected and degraded text recognition
Inventor: KUO SHYH-SHIAW
IPC: G06V30/196
Filed: 1992-10-26
Granted: 1997-09-16
Abstract: The present invention provides a method and apparatus for enhancing and recognizing connected and degraded text. The enhancement process comprises filtering a scanned image to determine whether a binary image value of an image pixel should be complemented, determining whether complementing the value of thepixel reduces the sharpness of wedge-like figures in the image, and complementing the binary value of the pixel when doing so does not reduce sharpness. The recognition process may comprise determining primitive strokes in a scanned image, segmenting the scanned image into sub-character segments based on the primitive strokes, identifying features which characterize the sub-character segments, andcomparing identified features to stochastic models of known characters and determining an optimum sequence of known characters based on the comparisons through the use of Viterbi scoring and level building procedures.

Title: Communications access network routing
Inventor: DAUGHERTY THOMAS HENRY
IPC: H04Q3/58
Filed: 1994-02-07
Granted: 1999-07-20
Abstract: A communications switch (311) communicates a message to a particular access network endpoint (OE i) by forwarding an identification of that endpoint along with the message, link-by-link, through the access network, the forwardingbeing accomplished by using previously stored routing information identifying, at the switch and at each cross-connection point (350, 370), a particular downstream link over which the endpoint can ultimately be reached. The links (345, 365) connecting the cross-connection points are time-division-multiplexed links supporting digital loop carrier and fiber-in-the-loop communications. The routing information is generated and stored automatically by having each network elementreport information about itself upstream into the network.

Filed: 1994-03-25
Granted: 1998-06-23
Abstract: A needle holder assembly having a sleeve that slidably receives a needle holder having a needle assembly attached thereto. After the need holder assembly has been used to collect a sample of body fluid, the needle holder is slid from its initial retracted position to a permanently locked extended position. In the extended position the used needle is contained within the sleeve of the assembly and can be disposed of. The assembly of the present invention includes a mechanism for smoothly releasing the needle holder from the retracted position, an improved mechanism for permanently and securely locking the needle holder in the extended position, and a body fluid collection channel around the distal end of the sleeve that prevents body fluid from splattering from the distal end of the assembly, when the sleeve is locked in the needle holder.

Granted: 1999-02-09
Abstract: A method for rotating bi-level image data plus or minus 90°. An 8 x 8 pixel block is selected for rotation from the image data and, using lookup tables, an intermediate matrix is generated dynamically and  stored  into  two  32-bit  registers  in  the processor.  Generation of the intermediate matrix partially rotates and stores the odd-numbered rows from the block of data in the first 32-bit register and the even-numbered rows from the block in the second 32-bit register. The first and second registers are copied,  respectively,  into third and fourth 32-bit registers. The first and second registers are then  shifted  one  bit  in  opposite  directions.  The  first register is logical ORed with the fourth register, and the second register is logical ORed with the third register so that the even bits are replaced in one register and the odd bits in the other. These steps are repeated for all remaining blocks of image data.
