Apparatus and method for producing statistically valid discriminable signals
First Claim
1. Signalling apparatus for use with an examination system, said examination system being arranged for examining an object to provide electrical input signals to said signalling apparatus, said input signals having a range of repetition rates which are a function of predetermined characteristics of said object, said signalling apparatus comprising means for processing said input signal, said processing means processing all input signals without deriving any squelch level, said processing means comprising:
- counting means, rate establishing means, and responsive means, said counting means counting said electrical input signals from said examination system, said rate establishing means establishing a plurality of respective count ranges, said plurality of count ranges being arranged in numerical sequence, with each one of said plurality of count ranges having a mean value which is a predetermined value different from the mean value of numerically adjacent count ranges, said plurality of count ranges comprising counts covering an entire range of said repetition rates of said electrical input signals, said responsive means being responsive to said counting means and coupled to said rate establishing means for producing an output signal for each of said count ranges representative of said predetermined characteristic of said object, each of said output signals being readily discriminable from every other of said output signals by a human being.

Abstract
An apparatus and method for producing audible signals, which are representative of the level of detected radiation from a probe, and which are statistically valid. The output of a radiation detector is a series of pulses, which are counted for a predetermined amount of time. At least two count ranges are defined by circuitry in the apparatus and the count range which includes the input count is determined. For each count range, an audible signal is produced which is audibly discriminable from the audible signal produced for every other count range. The mean values of each count range are chosen to be statistically different, e.g., 1, 2, or 3 standard deviations, from the mean of adjacent lower or higher count ranges. The parameters of the audible signal, such as frequency, voice, repetition rate, and/or intensity are changed for each count range to provide a signal which is discriminable from the signals of any other count range.

48. A method for locating radiation emitting sources in living beings comprising the steps of:
-
(a) placing a radiation detection probe, which generates a series of electrical pulses over a range of repetition rates over part of the body of said living being; (b) processing said electrical pulses without deriving any squelch level, said processing comprising the steps of; (1) counting the pulses detected by said probe for a predetermined amount of time; (2) establishing a set of count ranges which include a full range of said repetition rates; (3) establishing a signal for each of said count ranges which is discriminable from the signal generated for every other of said count ranges; (4) comparing each of said count ranges to the count detected for said predetermined amount of time; (5) selecting the count range in which said detected count is included; and (6) producing an output signal which comprises said established signal for the count range which has been selected. - View Dependent Claims (49, 50, 51, 52)
