SU:\J:\·L<\RY OF ACTIVITY FOR THE QUARTER E:>TDD:G Dcc~mber 31. 1966 Contract efforts durin~ this period ha~e been in three areas; literature monitoring, a continuation of effor-ts to produce an improved piezoelectric gener-ator design. and planning for animal research studies. The results of acti;..-ity in these areas are summar-ized separately below. Many articles of peripheral relevance to this study have been scanned. The sources utilized during this period are largely composed of the Biomedical Engineering Journals and publications or NASA and NIH.

Descriptions of recent work of three research groups mentioned in our last formal .report are contained in Proceedings of the Annual Conference on Engineering in Medicin~ Biolcgy. 1966. The report or P. J. Racine and H. L. Massie addres~ed the problem of determining the chemical activity present in the Koni~of£­ Reynolds Galvanic Electrode System. Data from severa.l metal t)'Pes in in vitro experiments are discussed. oxidation of electrode metal to its ion and rc:1uction of free oxygen were suggested as principal reactions.

Below the title, text explains that the document was obtained from The Black Vault, an online database of declassified government documents, specifically mentioning the MKULTRA/Mind Control Collection. The text further states that this collection contains over 20,000 declassified pages from the CIA and provides a URL for free download. There are no photographs, handwritten annotations, official stamps, forms, diagrams, tables, redactions, or visual evidence of experimental procedures visible on this page. This declassified document is a typed letter dated January 10, 1967, addressed to "Dear Neal." It states that a short progress report is enclosed. The signature line reads "Very truly yours," followed by an obscured area that would typically contain the sender's name. In the bottom right corner, there is a handwritten annotation circled, reading "271."

KeMedy device. B. Piezoelectric Generator Design The main problem to be overcome by a successful generator design is coupling the available form of host mechanical energy into the piezoelectric element. Fluid seals, overall efficiency, breakage, size and weight are some of the aspects ot thi_s problem. ·In our previous re- . . .. port ~·•e offered some suggestions. apropo~ par':s of this problem, among them . a striker system which\vas s\mila·~. to the-operation of a. rnusic bo:-c. · The intend-ed performance characteristic' w.a s for L,put mechanical energy to be captured in the piezoelactric ~lement \vhich would subsequently oscillate freely until the en~rgy was all converted into heat {mechanical losses) and electricity. Another method of achieving this characteristic has occurred to us which has th~ adv~ntage of:requiring no siiding off the end of th.e •. element thus eliminating a possible \vear point. The essence of this ne'v method is to attach a small piece of steel to the piezoelec.tr ic element and use a magnet to deform the element. \Vhen th~ magnet's holding force is excce:jed, the element is released and allowed to vibrate freely. It appe::~.rs that a pack:1ge simibr to those used by Dr. Kennedy but incorporating this 'technique could be constructed quite simply. .i\s has been previously discu:»sed, rcson:1nt operation should provide significantly more electric3l output than does "direct'' drive. --· .. .. ~ -3- C.
