Filed: 1993-04-19
Granted: 1997-11-18
Abstract: An image corresponding to a single sheet of recording paper is divided into three decomposed images each having the substantially same expansion as that of the image, and one of the decomposed images is recorded on the recording paper while a drum is rotated and the recording head is continuously moved at a distance corresponding to a width of the recording head.

Title: Keyword/non-keyword classification in isolated word speech recognition
Inventor: SUKKAR RAFID ANTOON
IPC: G10L15/00
Filed: 1993-08-26
Granted: 1997-09-23
Abstract: A two-pass classification system and method that post-processes HMM scores with additional confidence scores to derive a value that may be applied to a threshold on which a keyword verses non-keyword determination may be based. The first stage comprises Generalized Probabilistic Descent (GPD) analysis whichuses feature vectors of the spoken words and the HMM segmentation information (developed by the HMM detector during processing) as inputs to develop a first set of confidence scores through a linear combination (a weighted sum) of the feature vectors of the speech. The second stage comprises a linear discrimination methodthat combines the HMM scores and the confidence scores from the GPD stage with aweighted sum to derive a second confidence score. The output of the second stagemay then be compared to a predetermined threshold to determine whether the spoken word or words include a keyword.

Granted: 1998-11-10
Abstract: In a process for the manufacture of a molded part from a non-porous, elastic polyurethane, the starting components are individually isothermally transported from storage tanks through closed loop conduits and pumps into a mixing head.  Mixing of the components is carried out in the mixing head at a pressure of at least 150 bar and the resulting mixture is then expelled from the mixing head and into a mold.  This process obviates the annealing step required in conventional polyurethane casting processes for solidification of the molded part manufactured therewith,  Apparatus for the carrying out of the process are also disclosed.

Title: Channel utilization method and system for isdn
Inventor: GAGLIARDI UGO O
IPC: H04L47/76
Filed: 1991-05-24
Granted: 2000-04-25
Abstract: An ISDN gateway (GW, 100) dynamically allocates bandwidth by monitoring traffic at each destination queue and in response allocating or deallocating virtual B-channels. A long term allocation (LTA) algorithm is executed during usual traffic conditions to determine when, and for how long, virtual B-channels are to be allocated. During transient conditions, the gateway (GW, 100) executes a short term allocation (STA) algorithm. Bandwidth utilization is optimized by packaging data packets into trains that are transmitted to the destination when the train is complete and upon satisfaction of other conditions. Each train undergoes data compression by execution of a suitable compression algorithm.

Abstract: A  belt conveyor  is provided to feed veneers  in  the arrow-marked direction in the drawing.  A  porous transfer belt   having   numerous of air holes  therein  is stretched around so as to run above said belt  conveyor.      Inside the porous transfer  belt, a suction hood   which has  a  plurality of small air passages  formed  in  the running  direction  of the porous conveyor belt  is installed  to  rotatably  accommodate  a  damper   further therewithin.   The damper makes  intermittent  rotations to  open or close the sucking section such that  only  a desired veneer is selectively sucked for sort-out transfer  with  the  result that the need  for  piercing  the veneer  or defining in advance a gap between each adjacent  two veneers  is eliminated. Therefore, it  is  now possible  to  perform  high  speed  sort-out  operations without  subjecting  the veneer to  damage  or  breakage resulting  from tensile strength exerted thereon at  the time of defining the gap.

Title: Transmitting and receiving apparatus and method including punctured convolutional encoding and decoding
Inventor: TZUKERMAN SHIMON
IPC: H04L27/18
Filed: 1994-05-24
Granted: 1999-05-25
Abstract: Digital      data (particularly     encoded television program signals) are communicated from a transmitted to a terrestrial receiver by convolutional encoding the data into a first and a second signal during different periods representing a rate 1/2 signal. During the different periods, the two signals are combined and punctured into one serial punctured bit stream for producing a forward error encoded signal having a manually or automatically selected rate e.g. rate 2/3 or 6/7. Signals being encoded into different variable rates are transmitted at mutually exclusive times at first and second power levels to the receiver via a satellite. At the variable rates, parallel puncture bit streams are simultaneously derived and modulate simultaneously the pair of orthogonal carriers (QPSK). The improved puncturing method is capable of handling all of the optimum punctured codes and uses a punctured clock, multiplexer, FIFO, RAM, ROM, rate control source. The punctured clock is used to derive a pair of wavetrains the I and Q channels sequential bits and dummy bits inserted into the serial signal. The receiver responds to the QPSK carrier and derives first a serial signal having one sequential bit stream of alternating both I and Q sequential bits. Further they are sequentially as signals I and Q at the same time slots.

Title: Method and apparatus for bus access arbitration of nodes organized into acyclic token passing and alternatively propagating request to root node and grant signal to the child node
Inventor: OPRESCU FLORIN
IPC: G06F13/40
Filed: 1993-12-16
Granted: 2004-02-10
Abstract: A bus arbitration scheme is implemented in a system where an arbitrary assembly of nodes on a system bus have been resolved into an acyclic directed graph. The hierarchical arrangement of nodes has one node designated a root while all other nodes have established parent/child relationships with the nodes to which they are linked. Each node may have a plurality of connected child ports with a predetermined acknowledgment priority scheme established. Fair bus access arbitration provides for bus granting in a sequence corresponding to the predetermined port priorities allowing all nodes a turn on the bus. The root node may always assert its priority access status to gain bus access which is useful for accommodating a root node which requires isochronous data transfer. Alternatively, a token passing arbitration scheme may be implemented where the token for bus access is passed around the nodes according to the above-described predetermined port priority scheme. Preemptive bus initialization may be triggered by any node upon detection of a necessitating error or addition or removal of a connection to an existing node.
