Title: Null processing receiver apparatus and method
Inventor: GROBERT PAUL H
IPC: H01Q17/00
Filed: 1987-03-12
Granted: 1992-12-15
Abstract: ABSTRACT OF THE DISCLOSURE          A null processing receiver apparatus that receives and combines together a number of modulated information signals in such a fashion that an interference or jamming signal super-imposed on each received signal is substantially eliminated from the combined signal.  The apparatus first demodulates each received signal to baseband, to produce a primary demodulated signal and one or more auxilliary demodulated signals.  The apparatus then appropriately weights the one or more auxiliary signals and sums together the weighted signals with the primary signal to produce a sum signal in which the interference is substantially nulled out.  The weighting is based on a cross-correlation of the sum signal with the baseband signals themselves.

Abstract: AGGLUTINATION IMMUNOASSAY AND KIT FOR DETERMINATION     OF A MULTIVALENT IMMUNE SPECIES USING          BUFFERED SALT WASH SOLUTION          Abstract of the Disclosure A test kit is used in an agglutination immunoassay to determine a multivalent immune species, such as Streptococcus A antigen, in a bio-logical sample.  The method includes contacting an aqueous solution of the species with an agglutination indicator reagent having receptor molecules reactiue with the species to form an agglutinate of the reac-tion product of species and receptor.  These receptor mnlecules are bound to polymeric particles which contain tracer molecules.  The resulting agglutinate is captured on a microporous membrane which has an average pore size which is at least five times greater than the average diameter of the polymeric particles.  Unagglutinated residual materials are washed through the membrane using a wash solution. This solution has a pH of from about 5 to about 10 and an ionic strength of at least about 0.25.  Tracer is then determined either in the agglutinate or in the residual materials.  The test kit includes the agglutination indicator reagent, the wash solution, and optionally an extraction composition.

Abstract: ABSTRACT OF THE DISCLOSURE A  mechanism  for  extruding  and  retracting  the writing member of a writing instrument which is set ready for writing by pressing a clip member vertically movable in a slit bored in the rear side wall of a cylinder, but held in a protruded state while the writing instrument is not set for writing.   The clip member presses a flexible working element arranged under the clip member and having a plurality of elastic zigzag bent portions.  The working element thus pressed down axially extends to press the back of the writing member contained in the front part of the cylinder and energized backward by spring means and moves the writing member forward.  The tip of the writing member is protruded from the opening at the front end of the cylinder and the clip holder of the clip member is held inside the slit during writing.   On the other hand, the  clip  member  is  released  from  pressing  the  bent portions so as to restore the flexible working element to the bent condition in the original position and the clip holder of the clip member is again protruded from the side wall of the cylinder to place the writing instrument in the non-writing state.

Abstract: ABSTRACT     A method of inputting to a program or virtual process information from an external source such as another independently running process or an I/O device.  Information is transmitted to a program by means of events, which may be selectively retrieved from an event queue by the program.  User input such as that from a keyboard or mouse-type device, is treated specially to insure that the input goes to the proper program in a multi-processing environment.  A keyboard driver is included that has the capacity to use individual translation tables for each individual application program which is running.  User input from user activated devices, such as a keyboard or mouse, are combined with input from other parts of the systems by an input funnel which insures that user input is routed to the proper destination.  The input funnel operates in conjunction with a window manager to allow a user to type a sequence of keys which may be directed to several different programs which are running.
