of such analysis can be used to determine whether or not further intervention such as changing the medication schedule or the type of medication is desirable the system 10 can also include a magnetic recording system the recording system can record on a relatively long term basis results of diagnostic tests information concerning patient activity dispensed medication and any other information of value in improving the quality of patient care the various elements of the system 10 function with a control unit 46 the control unit 46 could include a programmed computer fig2 illustrates a perspective view of an alternate embodiment 50 of the system 10 the system 50 includes many of the functions and capabilities previously described with respect to the system 10 such elements are identified using the same identification numerals as were used with respect to the system 10 in addition the system 50 provides additional capabilities and functions not present in the system 10 the system 50 in contradistinction to the system 10 is moveable under the command of the internal programmed control computer 46 the moveability of system 50 permits it to move toward the bedside or chair of the patient for ease of interaction with the patient control over the movement of the system 50 by the computer 46 is effected by an ultrasonic system 52 the ultrasonic system 52 includes both a transmitter and a receiver 52a and 52b respectively the ultrasonic system 52 can detect transmission from a patient carried transmitter the patient carried transmitter can be used to inform the system 50 of the location of the patient.
