Abstract: Abstract of the Disclosure In the transmission of PCM coded picture elements (pels), the level value of each pel of an image is quantized in accordance with one-of-a-plurality of quantization schemes which is determined by the quantized level values of adjacent neighbor pels.  Each of the quantization schemes is configured from the relative frequency of occurrence of each pel level value for a given combination of neighbor pel level values.  Various embodiments may involve grey-level values of each pel of an image, the three-dimensional red, green and blue level values of an image quantized in accordance with a three-dimension quantization scheme determined by the three-dimensional quantized level values of adjacent neighbor pels, or three-dimensional color values which a pre-quantizer quantizes and linearizes into one-dimension which are then conditionally quantized using one-dimensional grey-level techniques.

Abstract: ABSTRACT            The  invention  is a  method and  apparatus  for counting multiple categories of combinations of threshold and window event signals generated by  a multi-parameter  flow cytometer  instrument.    The generation of event signals for each monitored parameter indicates that the detected parameter signal is above one or more pre-deter-mined thresholds and/or within one or more windows or ranges.     Counting the  occurrence  of each of  said combinations  is accom-plished by using the  event signals as an address code which is applied to a pre-programmed memory.    Said pre-programmed memory generates data corresponding to a relative address location  for each combination of the multiple-category event combinations.   The relative address is used by a microprocessor to access a particular address  location of  a  random access memory,   the  data at  said particular address location being incremented each time the data is so accessed.    The data in the address  locations of  the random access memory may be displayed or used for analysis or experiment control purposes.

Abstract: Abstract A  frequency  and  phase  demodulating  circuit  provides  direct frequency  demodulation  utilizing  only  addition,  subtraction  and multiplication  steps.   Division of signals  is avoided,  as  is the need for a look-up table of trigonometric values corresponding to the  results of  such  division.   By  maintaining  a  substantially constant  input  amplitude  to  a  quadrature  sampler,  a  number  of approximations   may  be  made  without   introduction  of   error.          Compensation for actual signal variation, as well as for first order errors due to the approximation process of the invention, results in accurate  frequency  evaluation  and  avoids   the  necessity  for differentiating an initial phase determination.

Abstract: ABSTRACT     A planar, biaxially heat-shrinkable, plastics mesh layer is fixed to a planar, relatively non-heat-shrinkable plastics mesh layer at zones which are spaced apart on a generally square grid, and the structure so formed is heated to cause the shrink layer to shrink biaxially and thereby cause the non-shrink layer to assume a cuspated configuration. The structure can be shipped as a semi-finished product after fixing the layers together and before heating, thereby reducing bulk and hence shipping costs.

Abstract: ABSTRACT                 AN ADJUSTABLE FIREARM STABILIZER           A stabilizer, for firearms which fire a single projectile from each shell, which is attached to the muzzle of the firearm to control muzzle climb during firing.  The stabilizer is adjustable in both the magnitude and direction of the forces which counter muzzle climb.  The stabilizer is able to be adjusted for the individual characteristics of the firer as well as varying powder loads in ammunition.  A body of the stabilizer is attachable to the muzzle of the firearm so that gas vent slots and gas screen ports may be oriented from the vertical in any desired direction.  An adjustable nose cap is threaded into the body any desired portion of the length of the body and the nose cap may cover or expose any of the gas vent slots or a portion of one of the gas vent slots thus controlling the space through which escaping gases may escape, and consequently controlling the magnitude of the force countering the muzzle climb.  The stabilizer is readily adjustable in the field or on the firing range without carrying spare parts or replacement items.

Abstract: ISOLATED IDLE LOOP FOR CARTRIDGE INSERTION/REMOVAL     ABSTRACT            A computer system with provision for inserting/removing memory cartridges is improved by inhibiting erroneous operation as a result of noise produced on insertion/removal of a memory cartridge.  Removable cartridges are connected/disconnected from a cartridge bus which is distinct from the system bus to which all other components are coupled.  A controlled isolation is provided between the two buses.  An idler routine ensures that in the absence of operator requested tasks the isolation prevents noise on the cartridge bus from reaching the system bus.  When the processor executes an instruction (or only selected instructions) the isolation is disabled so that data/instructions can flow to/from the system and cartridge bus.
