Abstract: The computer input device includes an elastic actuator button of generally hemispheric shape. An applied force causing an indentation in a curved portion of the button is transmitted via the material of the button to cause a corresponding elastic bulging of a bottom, normally flat portion of the button and of a conductive film and resistive film which are attached thereto. During such bulging, a portion of the resistive film is urged into contact simultaneously with two or three oppositely disposed conductive traces. This action can cause a cursor to be moved in a direction corresponding to the direction of force of the push when the device is attached to the proper circuitry. The amount of pressure applied to and transmitted through the elastic material of the button determines the size of the area of contact between the resistive film and the pattern of conductive traces and, ultimately, the speed and/or distance of movement of the cursor in that direction.

Abstract: A method of simulating a positive response by volatile organophosphorus ers to an ionization detector system which comprises forwarding to the ionization detector system a gaseous stream comprising water vapor and a di(lower alkyl) sulfoxide or a cyclic sulfoxide represented by the formula I: ##STR1## wherein R is hydrogen or a lower alkyl group, in an amount sufficient to elicit a positive response by the ionization detector system.

Abstract: A method for the treatment of pathological processes in bone and connective tissue comprises the topical application of calcitonin to effect control of said processes by transepithelial action. Preferred compositions for use in the method are ear drops comprising an aprotic solvent or an aqueous medium containing a surface active agent.
