Abstract: Apparatus and method for sensing, recognizing, displaying, processing and storing motion generated symbolic information including a hand held, mark-forming writing instrument having motion sensing means and a wrist mounted display communicating with the writing instrument through character recognition circuitry to simultaneously display information formed by the writing instrument. An information control and storage circuit is included capable of operating in any one of several possible modes to receive, store and cause the display of information thereby permitting a multiplicity of functions heretofor requiring a vastly greater number of physical components. In particular, this highly portable apparatus readily and broadly compliments the kinesiology of writing instruments and composures that accompany human thinking and problem solving. The operational modes include horological display, data calculation, reminder message storage and display, and financial account storage.

Abstract: This invention relates to a medical clamp for controllably occluding extremely small body vessels such as blood vessels within the intracranial or intraspinal areas of the human body. The disclosed clamp is preferably formed from a U-shaped unitary body of transparent, resilient elastomeric biologically inert material such as Tygon or Silastic wherein the leg members of the U-shaped body are controllably brought together to occlude a vessel placed therebetween by means of a flexible line or spring. Several embodiments are disclosed illustrating various expedients for securing the flexible line such as a sliding friction device or latch plate, and for operating and securing the string mechanism. All embodiments include means for measuring and detecting the termination of fluid flow through a vessel being occluded. Such measuring or detecting means permit the use of only that amount of pressure and no more than is necessary to cause vessel occlusion.
