IPC: G06F3/048
Filed: 1990-07-20
Abstract: A  processing  system  for  identifying  operator selection of a graphics object in a system using parallel pixel generation.  Parallel pixel generation results in a fragment comprising a series of M pixels being generated at each processing cycle.   The image fragment must be tested against  an operator defined  selection area  to determine whether the object being generated falls within the operator  selection area.   Fragments  are  initially classified as totally within or totally outside of the area.   If a fragment intersects the operator selection area, applying a mask for each boundary of the operator defined area.   Selection is  signalled based upon  the logical  combination  of  the  masked  image  fragments. Operator selection or picking occurs without the overhead of maintaining a pick RAM for the X and Y dimensions.

Abstract: An automatic channel sampler system, including a television signal tuner, displays an array of inset pictures on a display screen each time the receiver is turned on. Each inset picture is a still video picture (i.e, freeze-frame) selected by tuning each of the channels in a scan list of channels. Automatic channel sampling is initiated in response to the development of operating power, and is performed while the picture tube is dark during the time in which the picture tube is warming up. A separate user-enterable scan list may be provided for either the automatic channel sampling function, a manually initiated channel sampling function, or both. The separate scan list may be programmed to contain only those channels which the viewer regularly watches, and would have the triple advantages of excluding the sampling of channels carrying programming which is not of interest to the viewer, presenting the sampled images in whatever order is desired by the user, and shortening the time necessary to complete the channel sampling function by eliminating the sampling of the undesired channels.

Title: Stability compensated broadband source
Inventor: WYSOCKI PAUL F
IPC: G01B9/02
Filed: 1991-09-17
Abstract: The present invention discloses a thermally stable rare-earth doped fiber source (100) comprising an active medium (110) such as Erbium or Neodymium. The thermal stability of the mean wavelength of such a source (100) is determined by three contributions as expressed by the following differential equation:               The first term is the intrinsic temperature dependence of the active medium  (110),  the second term is the pump power dependence and the third term is a contribution that arises from the dependence of the emission wavelength on the pump wavelength.  The method of the present invention  minimizes the temperature dependence of the mean wavelength by using the above equation and optimizing the values of the pump power and the pump wavelength so that the three contributions in the governing equation cancel each other.

Abstract: MAGNET SYSTEM                            ABSTRACT          In  a  known  magnet  system,   in  particular  for magnetic   separators,    with   homogeneously   magnetized, circularly  arranged  magnetic  blocks,   the  directions  of magnetization of  the magnetic blocks are  aligned variably among  one  another  and  are  established  according  to  a predetermined mathematical formula.   In this way, a magnetic field is created which is uniform across the entire range of the magnet system.   However, the magnetic blocks are in this case of a trapezoidal shape cross-section and require special manufacturing  because  of  the  different  directions  of magnetization.    The production and the assembly of these magnetic  blocks  are  therefore  relatively  complicated  and expensive.   However, according to the present invention, the manufacture and the assembly of the magnetic blocks  to a magnet  system  is  simplified  significantly  by  making  the cross-section of the magnetic blocks of regular polygonal to circular shape.
