Abstract: ABSTRACT OF THE DISCLOSURE      Circuitry for digitizing received light into a digital pulsating signal, including a photodiode operable in response to light intensity for passing current to a capacitor for developing a voltage level thereacross.  A voltage comparator with a hysteresis responds to the magnitude of the capacitor voltage level for tripping the comparator's output between a HIGH and LOW state which directs capacitor discharge to cycle the comparator output in a pulsating manner.       In a preferred embodiment, the circuitry is powered by a flash storage capacitor along a pair of conductors which serve both to power the circuitry and to receive pulsating current levels indicating voltage comparator switching.  The current levels are sensed and counted for producing a binary count output of received light energy.  In another embodiment, the conductors also serve to carry a trigger signal for directing flash initiation.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved nephelometer for immunochemical complex assay measures forward light scatter in samples.  The angle of forward scatter, about 30°, is small enough to result in a large amount of forward scatter from the immunochemical complex particles which are to be assayed, whose size is of the order of the wave length of the light used in the optical system.  Forward scattering from smaller particles, such as from molecules of buffer, antibody and serum, is constant during the course of a test, and is compensated for by the use of subtraction circuits which are readily and semiautomatically adjusted to subtract proper values, in accordance with the readings taken on standard or "blank" samples of buffer, antibody and serum.  Forward scattering from large particles, such as dust, is variable, and results in fluctuating signals, which are electrically processed to ignore the spurious peaks.  The results of a test are displayed on a digital read out meter.  Also described is a method of and protocol for immunochemical assay, whereby the amount of antigen originally present in a sample is determined by adding a known amount of antibody, and by assaying the "blank" component ingredients and the resulting mixture.

Abstract: CODING SCHEMES FOR ACOUSTIC DELAY    LINE DATA COLLECTION SYSTEM                   Abstract A magnetoacoustic system adapted to use as a keyboard can employ a serpentine acoustic delay line passing under a number of transducers which are activated simultaneously with a current pulse through the wire.  Magnets adjacent to the wire generate magnetoacoustic pulses along the wire which arrive sequentially at a sensor at one end of the line.  For each key on a keyboard at least two magnets are associated with each key position with one magnet affixed in position and one reciprocably movable towards and away from the wire in a response to actuation of the key. The magnet which remains close to the wire is used to provide a "location" signal indicating the location along the delay line provided by the wire by producing an acoustic pulse for that point on the wire for each clock pulse of current which passes through the wire.  The second magnet located adjacent to the first magnet generates a pulse simultaneously with the other magnets when the current pulse passes through the wire, but it is delayed by the physical displacement along the wire, so it is received at a different time than the pulse from the other magnet.  The data pulse can follow or precede the location pulse so long as the presence of one or both can be readily decoded.  A three magnet key arrangement can be employed where it is desired to be able to use three positions per key.
