System Of Improving Signal-To-Noise Ratio Of Detected Random Pulses
View pageUS Patent:
48706035, Sep 26, 1989
Filed:
Feb 16, 1988
Appl. No.:
7/155785
Inventors:
Gerald M. Padawer - East Hills NY
Assignee:
Grumman Aerospace Corporation - Bethpage NY
International Classification:
G04C 2338
US Classification:
364574
Abstract:
The invention detects pulses, and, in response thereto, generates ramp functions with amplitudes corresponding to the interarrival times between successive pulses. These amplitudes are measured, and the occurrence of identical amplitudes are accumulated in corresponding memory locations, each of which has an address corresponding to a particular interarrival time. The resultant memory contents define a population distribution of interarrival times which is an exponential decay function of interarrival time. Interarrival times exceeding a preselected value are disregarded.
Positron-Annihilation-Radiation Transmission Gauge
View pageUS Patent:
44632630, Jul 31, 1984
Filed:
Sep 30, 1981
Appl. No.:
6/307279
Inventors:
Gerald M. Padawer - East Hills NY
Assignee:
Grumman Aerospace Corporation - Bethpage NY
International Classification:
G01T 120
G01N 2300
G01N 2300
US Classification:
250363R
Abstract:
A radiographic method and apparatus for nondestructively monitoring a specimen for density variations are disclosed. A positron-annihilation-radiation-emitting point source is situated approximately midway along the axis separating two detectors sensitive to positron-annihilation (0. 511-MeV photon) radiation. The outputs of the two detectors are fed to an electronic circuit that reckons only time-coincident events that are sensed simultaneously in the two detectors. The specimen to be measured is positioned between the source and one of the detectors such that the cone of detected, i. e. , coincident, photons intercepts the region of interest. The number of coincidences that are counted in a preset time interval are recorded, or, alternatively, the coincidence count rate is monitored directly with a ratemeter. A linear scan of the region of interest is performed by the sequential displacing of the source/detectors axis with respect to the measured specimen, or the specimen with respect to the source/detectors axis. The number of coincidence counts accumulated within a preset time interval are recorded for each displacement.

Filed:
Feb 16, 1988
Appl. No.:
7/155794
Inventors:
Gerald M. Padawer - East Hills NY
Assignee:
Grumman Aerospace Corporation - Bethpage NY
International Classification:
G01R 2316
US Classification:
324 77R
Abstract:
The invention detects pulses, and, in response thereto, generates ramp functions with amplitudes corresponding to the interarrival times between successive pulses. These amplitudes are measured, and the occurrence of identical amplitudes are accoumulated in corresponding memory locations, each of which has an address corresponding to a particular interarrival time. The resultant memory contents define a population distribution of interrarrival times which is an exponential decay function of interarrival time. Interarrival times exceeding a preselected value are disregarded.
