Abstract
Abstract This equipment tests several psycho-physiological functions, the main of which is the study of optical and material coordination. It is used for testing the alertness and rate of perception of the tested subject. The equipment consists of the following main components: a) Control mechanism; b) pulser; c) intermittent flash signals and their relay mechanism; d) testing timer; and e) recording mechanism (counter). Pulsations are omitted with a selected frequency which are transformed into flash signals, or other signs, pictures or symbols, which are visible on the frosted glass in the different spaces and at a different rate of speed. Testing can be performed in two ways: 1. Frequency of flash signals is automatic. 2. Frequency of flash signals is mechanical.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
122 words
A device for testing alertness and the rate of perception which comprises: a plurality of separate substantially identical visual signal means; a separate substantially identical hand operated response means associated with an immediately proximate each said signal means; a counter means; a timer; and control means for performing the functions of causing said signal means individually to emit signals one by one in a random sequence at a predetermined relatively rapid constant frequency and for a predetermined length of time governed by said timer and causing said counter means to record the number of total times in said length of time that said response means are individually activated while the individual signal means corresponding to the activated response means is emitting signals.
Claim 2
Independent Claim
122 words
A device for testing alertness and the rate of perception which comprises: a plurality of separate substantially identical visual signal means; a separate substantially identical hand operated response means associated with an immediately proximate each said signal means; a counter means; a timer; and control means for performing the functions of causing said signal means individually to emit signals one by one in a random sequence at a predetermined relatively rapid constant frequency and for a predetermined length of time governed by said timer and causing said counter means to record the number of total times in said length of time that said response means are individually activated while the individual signal means corresponding to the activated response means is emitting signals.
Claim 3
Dependent Claim
21 words
A device in accordance with claim 1 wherein means are provided for selecting different desired said frequencies for a given test.
Claim 4
Dependent Claim
15 words
A device in accordance with claim 1 wherein said signal means each comprises a lamp.
Claim 5
Dependent Claim
46 words
A device in accordance with claim 1 wherein said components are housed in a casing, said signal means and said response means all being mounted on one side of said casing, said counter means and said timer being mounted on the other side of said casing.
Claim 6
Dependent Claim
16 words
A device in accordance with claim 1 wherein said response means each comprises a separate key.
Claim 7
Independent Claim
132 words
A device for testing alertness and rate of perception which comprises; a plurality of separate substantially identical visual signal means; a separate substantially identical hand-operated response means associated with and immediately proximate each said signal means; a counter means; a timer; and control means for performing the functions of causing said signal means individually to emit signals one by one in a random sequence for a predetermined length of time governed by said timer whereby actuation of said response means corresponding to an individual signal means which is emiting signals terminates said signal emissions therefrom and at the same time actuates another individual signal means to commence emitting signals and causing said counter means to record the number of total times said response means are actuated during said predetermined length of time
Claim 8
Independent Claim
132 words
A device for testing alertness and rate of perception which comprises; a plurality of separate substantially identical visual signal means; a separate substantially identical hand-operated response means associated with and immediately proximate each said signal means; a counter means; a timer; and control means for performing the functions of causing said signal means individually to emit signals one by one in a random sequence for a predetermined length of time governed by said timer whereby actuation of said response means corresponding to an individual signal means which is emiting signals terminates said signal emissions therefrom and at the same time actuates another individual signal means to commence emitting signals and causing said counter means to record the number of total times said response means are actuated during said predetermined length of time
Claim 9
Dependent Claim
15 words
A device in accordance with claim 6 wherein said signal means each comprises a lamp.
