Hallis, James Outline, A Better Mousetrap?--Not really, just an ultra sensitive transmiter switch to be used to photograph a rodent's movement in a research project underway at the Universiity of Kentucky. James Hallis, head of the research electronics workshop at the Medical Center, is working on this and many other electronic "minatures'" including a transistor micrphone. Small batteries used in such devices are shown by Hallis. Two are on the switch at left and four others are in the package at right. Each has effective life of about eighteen hours.
