Abstract: DIGITAL IMAGE OVERLAY SYSTEM AND METHOD                         ABSTRACT            A data processing system is described which includes, among others,  three  memory  areas:   a  source  memory  which  is addressed in planar, data unit increments and stores display data units on a bit per plane basis;  a target memory for storing  display  data  units  in  a  manner  suitable  for operation  of  a  display  unit;  and  a  window  buffer  for transferring display data units from the source memory to the  target  memory.   The  system  includes  apparatus  for inhibiting certain data units from the source memory from overwriting data units already in the target memory.   The method  of  the  invention  comprises  first  accessing  a plurality of data units from the  source memory and then logically determining if all bits of each accessed data unit meet a predetermined criteria.  Each data unit found to meet the predetermined criteria is inhibited from altering any data unit already in the target memory.

Granted: 1996-07-09
Abstract: A process of immobilizing environmentally noxious organic, particularly aromatic, substances by absorbing same on a layered clay mineral modified by exchange with a quaternary ammonium compound, thereby increasing the spacing between the layers and rendering the adsorption surfaces hydrophobic.     After  adsorption  of  the  organic  compounds  the spacing between the layers of the layered clay mineral is reduced  by  a  layer  spacing  reducing  agent,  and subsequently the clay mineral comprising  the organic compounds is mixed with a hardenable inorganic binder and the whole is hardened.     A  typical  example  of  a  modifying  agent  is  a quaternary ammonium compound,  and of a  layer spacing reducing agent an alkaline substance,  such  as sodium hydroxide.     Typical clay minerals are chosen among the smectite minerals, tectosilicates and phyllosilicates, preferably monthmorillonite clay is used.     The inorganic binder may be a calcium hydroxide compound or  a  calcium containing  cement,  preferably containing fly ash.

Title: Procedure for determining the range and direction of sound-producing targets
Inventor: GROSCH HERMANN
IPC: G01V1/00
Filed: 1990-09-25
Granted: 1995-09-12
Abstract: This patent discloses a procedure in which only passive sensors are used to determine the range and direction of sound producing targets.  To this end, it is proposed that in addition to the acoustic sensors that are usually required to determine the bearing angle, a seismic sensor is also used in order to measure the range to the target.  Then, for a signal source that is characteristic of the target, a characteristic line is measured in both the airborne-sound and in the ground-sound spectrum, and the radial target speed (Vz,r) is determined from the Doppler shift of these lines and from the propagation speed (C) of the corresponding waves, when one computes the target range (r) from this, taking into account the bearing angle (.alpha.).

Title: Method for enacting failover of a 1:1 redundant pair of slave processors
Inventor: MCLAUGHLIN PAUL F
IPC: G06F11/20
Filed: 1991-09-19
Granted: 1998-07-07
Abstract: A primary slave IOP, upon detecting an error, verifies the availability of a secondary slave IOP, and then sets an output control signal to indicate backup is requested.  The primary slave IOP then takes itself out of being the primary.  A secondary slave IOP, sensing that the output control signal from the other IOP has been set, assumes the role of the primary slave IOP.  A master controller, detecting an error with the primary slave IOP, interrogates the primary and secondary slave IOPs for a status input, and then arbitrates between the first and second IOP to determine the IOP that is to take on the primary role.  Finally the master controller awards the more operational IOP the role of the primary slave IOP, thereby completing the failover operation.     A primary slave IOP which fails sets the output control signal as part of its failure handling and watchdog timeout function.  The output control signal is also set to indicate backup for an unpowered IOP.
