A rotary displacement measuring apparatus includes an axle whose rotary displacement is to be determined, with the axle being mounted to rotate about its long axis. An emitter is mounted on the axle to define a plurality of concentric tracks circumscribing the axle to rotate as the axle rotates, with each of the tracks being segmented to define a plurality of spaced-apart, conductive sections for producing electric fields when energized. Also included is a voltage source for energizing the conductive sections. A detector is disposed adjacent to the tracks of the emitter and includes a plurality of sensors, each positioned adjacent a respective track to detect the electric fields of the respective track as the axle and tracks are rotated. The detector produces signals representing the variation in the electric fields as the emitter is rotated, and these signals provide an indication of the rotary displacement of the tracks and thus of the axle.

A low-profile multipathway automatic drug delivery system utilizing a battery powered control pad coupled to a disposable drug storage and delivery system and strapped to a patient's limb or torso. A preprogrammed or on-demand drug administration sequence is input to the control pad. When a drug is to be administered, the control pad ignites a high energy density propellant charge in the drug delivery system. Expanding propellant gas exerts pressure on a drug in a second chamber and forces it from the storage reservoir. Depending upon the type of drug delivery system required for the drug being administered, the propellant will either: (i) force a hypodermic needle into a patient's muscle tissue, propel the drug in the storage container into the needle embedded in the patient, and withdraw the needle; (ii) force the drug from the storage container through a jet nozzle where the drug is injected into subcutaneous tissue; (iii) force the drug from the storage container into a patch for passive transdermal delivery; (iv) force the drug into a patch for iontophoretic transdermal diffusion; or (v) force together two drugs stored separately that are unstable when mixed, and then administer them through one of the methods described in steps (i) to (iv).

A system for remotely monitoring personnel status includes a plurality of sensors disposable on a soldier or other person for developing signals which may be used to determine the physiologicalal status. The sensors communicate with a soldier unit which can process the information to ensure that the sensor data falls within acceptable ranges and communicate with remote monitors. The soldier unit also includes a global positioning system. By using the sensor data and the global positioning system, leaders and medics can quickly and accurately track and treat casualties in battle. The system enables more rapid location of the casualty, as well as remote triage/initial diagnosis, thereby assuring that those who are most in need of treatment are attended to first. Typically, the system monitors both body surface and ambient temperature, heart rate, shivering, motion status and body condition. Additional sensors can be provided to supply information on other physiologicalal parameter which may be desired for more thorough diagnosis.
