standards. The directive of the subpanel will be the seme as that 

for the Panel on Communications except for the limited field of 

interest. 

Action. ThB matter will be submitted to the Panel on Co·'llllunications 

for approval at its next meeting by J. z. liillar. 

2. Allocation of' Responsibility 

lJo action at this meeting • 

. 3. Summary Charts and Systems Projects 

The Service members bro~ht in notes on development proJects which nu.ght 

be considered systems developments. 

3.1 USAF. The i1atson Laboratories submitted one item from the 

summary charts and fron items not previously listed of' 'Mlich 

three uere nentJ.oned under section 3.5 of previous IIinutes 

(1UT/CPS-6B, AfT/.-ps-7 /. /PPS-3, and A.U/MSQ .. l). The systems 

of which these projects form a part, in a recommendation 

by the Panel -0n Radar, 'Jill be allocated to the US.AP. The 

proJect "Study of' AutoMatic Transmission of Information 

\".ri thin USAF Systems, 11 should be included under section on 

Inte~rated Systems in the next edition of the SUJm11ary charts 

of Research and Develop1r.ent Projects. Items 17 ';td 18 of 

Section on Terminal ~quip!1lellt, Teletype, are to be carried 

as primary responsibility of the Subpanel on Systems. 

ProJects 38 and 48 Research, are considered of secondary interest 

to the Subpanel on .Systems. It was suggested that a representative of the Cambridge Laboratory be invited to participate 

in the Subpanel on ::lys tems activity. 

It appears that the Belt Line project is of interest bo the 

Gub;?anel on Systems and jJr. Schram uas asked to investiGate
