Title: Method and apparatus for generating semantically consistent inputs to a dialog manager
Inventor: ABELLA ALICIA
IPC: G06Q30/00
Filed: 1998-09-24
Granted: 2002-02-12
Abstract: A  spoken  dialog  system  is  constructed  to sufficiently understand a user's response to the open-ended prompt 'How may I help you?' in order to route a caller to an appropriate destination, with subsequent processing  for  information  retrieval  or  call/task completion.  In this invention the relationships among the  call  types  are  structured  into  an  inheritance hierarchy.    Then  a  dialog  manager  exploits  this hierarchy  and  the  output  of a  spoken  language understanding module to generate a set of semantically consistent task objectives.

Title: Moving image encoding apparatus and moving image decoding apparatus
Inventor: AONO TOMOKO
IPC: H04N19/563
Filed: 1997-05-16
Granted: 2002-10-22
Abstract: When a background interpolation-judging section judges that parts areas of a lower layer and an upper layer move significantly, and a visual effect can be obtained by the background interpolation, a controller controls a switch based on the area information of the parts area of the lower layer to perform the background interpolation. A weighted average section takes an average by weighting the upper layer and the lower layer by using the interpolated background to generate an interpolated image. By using this interpolated image, the prediction-encoding/decoding of the upper layer is performed. On the contrary, when the background interpolation-judging section judges that parts areas do not move significantly, and a visual effect cannot be obtained by the background interpolation, a background is synthesized by using the output of the interpolated image-forming section to generate an interpolated image.  Hence, the shape information for the background interpolation is reduced and a high quality image can be obtained.

Abstract: The invention relates to a method for testing the authenticity of a data carrier (1) and/or an external device (2) which enters into data exchange with the data car- rier (1). According to the invention, the data carrier (1) and the external device (2) are each equipped with a special additional apparatus (4, 6) for generating and/or testing authenticity data. Data transmission between the data carrier (1) an d the ex- ternal device (2) as required for authenticity testing is performed at least partly via a special transmission channel (B). The transmission channel (B) for transmitting authenticity data is separated physically or logically from a transmission channel (A) for transmitting standard data so that there is no mutual interference of da ta trans- mission via the two transmission channels (A, B). In authenticity testing, t he addi- tional apparatuses for generating and/or testing authenticity data (4, 6) of the data carrier (1) and external device (2) and optionally also the transmission channel (B) for authenticity data must meet special demands which cannot be met by conve n- tional designs.

Title: Method and apparatus for improved mixing in fluids
Inventor: BIRCHER KEITH G
IPC: B01F13/10
Filed: 1998-09-21
Granted: 2007-05-29
Abstract: The present invention pro-vides an apparatus and method for accomplishing fluid disinfec-tion by passing fluid flow through a uniform array (3B) of ultraviolet lamps having cross sections per-pendicular to the direction of fluid flow that define channels (8) for the fluid flow. Positioned next to the end of each lamp (5) at the entrance of the fluid flow are tri-angular shaped delta wings hav-ing surfaces inclined at an an-gle to the direction of fluid flow.  The interaction of the fluid flow with each delta wing creates a pair of vortices (10) that rotate in the same direction or in direc-tions opposed to each other. The counter-rotating vortices (10) rein-force each other to minimize dissi-pation of their mixing strength as they move down the channel (8).  Due to these co-reinforcing prop-erties these counter-rotating vor-tices (10) more promote efficient mixing of the fluid which is re-quired to achieve more efficient use of the light in the UV  disin-fection systems, along with heat and/or mass transfer in chemical reactions. Although the present invention is described in particularity as embodied in a UV reactor system, it will be understood by those skilled in the art that the present invention has equal applicability to other types of arrayed flow systems in which increased fluid mixing is desired.
