Title: Secure access calling card for call payment data transmission
Inventor: SMITH WILLIAM K
IPC: H04M1/275
Filed: 1992-08-31
Abstract: ABSTRACT          This invention relates to the transmission of data corresponding to call payment information for long distance telephone charges over an acoustically coupled dial up telephone line, using Bell Standard protocol for DTMF tone groups.            The call payment information number represents a credit card number issued by the long distance telephone carrier, for the exclusive purpose of charging long distance telephone calls to a pre-authorized party, for billing purposes.            The call payment charge card, or Calling Card as it is referred to in the industry, is a passive, plastic card, with the card number imprinted upon the card in embossed lettering.            An active, electronic, alternative to the passive card is described which includes the basic functionality of the passive card, but allows the card number to be secured against unauthorized use, since the card number is not printed on the face of the card as with the passive card, and a secret access code is needed to access the number, which is stored in semiconductor memory, and is acoustically transmitted to the telephone carrier over the telephone line at the time the call is charged.
Patent CA-2083299-A1 (CA)
Inventor: BELISLE EDOUARD
IPC: A01M23/34
Filed: 1993-03-01
Abstract: Le piège comprend un bâti et une paire de mâchoires montées de façon pivotante au bâti. Chacune des mâchoires peut  être  déplacée  entre  une  position  ouverte  et  une position fermée où les mâchoires sont contre une patte de l'animal à capturer. Les mâchoires sont dépourvues de dents ou de portions acérées afin de ne pas blesser un animal capturé. Un lacet, pourvu d'une boucle anti-retour et ayant une extrémité ancrée à un arbre ou une racine, est disposé sous les mâchoires afin de se serrer autour de la patte de l'animal. Lors de l'utilisation du piège, l'animal qui se fait prendre cherchera à s'enfuir, ce qui aura pour effet de déplacer le piège. Toutefois, étant donné que le lacet est ancré,  il  se  refermera  sur  la  patte  de  l'animal  afin d'empêcher sa fuite. Ce dispositif permet donc la capture des animaux sans les blesser gravement, comme c'est le cas avec des pièges à mâchoires usuels.

Abstract: A  message  packet  transmitter  for  transmitting  a packet of electronic data signals onto a communication network  without  interruption.  A  first-in,  first-out electronic  memory  has  a  transmit  state  in  which  an electronic data signal  stored therein is output.   The electronic memory has an idle state in which electronic data signals stored therein are not output.  A message packet-in-transit  identification  circuit  generates  a packet-in-transit  signal  after  the  electronic  memory outputs the first electronic data signal in a message packet.  A no-packet-in-transit signal is generated after the electronic memory outputs the last electronic data signal  in  the  message  packet.   A  state  controller maintains the electronic memory in the  transmit state when the electronic memory stores at least a portion of a message packet,  when the  state  controller  receives  a packet-in-transit signal,  and when the state controller receives an interrupt-pending signal.

Title: Video scanning system
Inventor: GREEN JAMES C
IPC: H04N7/18
Filed: 1993-09-10
Abstract: VIDEO SCANNING SYSTEM     James C. Green Edwin A. Snyder Gilbert R. Woodman III         ABSTRACT OF THE DISCLOSURE       In a video scanning system, video camera coordinates of an image are converted to spatial coordinates of the imaged object using look-up tables.  The loop-up tables allow determining the spatial coordinates for every point on the camera screen at high speed with sub-pixel resolution.  The look-up tables are constructed by means of a zigzag-edged calibration fixture.  The spatial coordinate system is referenced to the calibration fixture and to the video scanning system to avoid any physical measurements during calibration.  The image point on each camera line is taken to be in the middle between two points at which the camera line signal crosses a threshold.  The threshold is the peak value of the signal minus a preset, software settable value.  Such threshold choice provides an accurate and stable estimate of the image point position.

Title: Structure, method of construction and use of a transmission filter for light
Inventor: RICHARDSON TIMOTHY M
IPC: G02B5/28
Filed: 1993-09-24
Abstract: ABSTRACT OF THE DISCLOSURE A stable filter is fabricated with a spectral transmission function that is the approximate reciprocal of the source radiation spectrum that is to be analyzed. The source light after passing through the filter will ideally be at an intensity of 1 unit for all wavelengths. In practise, filter technology cannot exactly produce the reciprocal of the source curve for a complex light beam passing through the filter, but the variation in intensity can be held to only a few orders of magnitude, asopposed to the ten or more orders of magnitude by which the source might vary without the filter. When this filter is placed in front of a monochromator and detector, it reduces the out-of-band light leakage to the point where a relatively inexpensive system that can attain only 2 or 3 orders of magnitude intensity dynamic range can now spectrally resolve a source having 10 or more orders of magnitude of dynamic range. This invention is particularly effective in resolving the spectral content of the sun's radiant light spectral curve in the UVB portion of the spectrum. The data obtained from the detector can be manipulated in a computer to recreate the original spectral curve of the photon source being analyzed.

Inventor: ITTNER DAVID J
IPC: G06V30/10
Filed: 1994-02-28
Abstract: The techniques for determining the orientation of lines in images disclosed herein take as their starting point an apparently universal typesetting convention: that symbols are generally closer to other symbols in the line to which they belong than they are to symbols in other lines. The techniques make a graph by connecting symbols in an image of a block of text with edges (lines) and then determine thepredominant orientation of the shortest edges. Because the symbols in a line arecloser to each other than to symbols in other lines, the predominant orientation of the shortest edges will be the same as the orientation of the lines. An advantageousmode of obtaining the shortest edges is to construct a Euclidean minimum spanning tree from the graph. A Euclidean minimum spanning tree of a graph contains all the nodes (symbols) of the original graph but connects the nodes with the shortest possible set of edges. The edges which predominate in the Euclidean minimum spanning tree are the shortest edges. Which edges predominate is determined by means of a histogram.
