7. The bi-directional adaptive drug dispenser as in claim 1 wherein said operations cap is programmed to effect delivery of a series of individual doses of one or more units of a medication according to a pre-set regimen, and testing and recording the actual performance and behavior, said programming further comprising the steps of:

activating a scheduled dose alert when the timer reaches the time set for the next dose;

sending the scheduled dose through the bidirectional dose checking tunnel from the storage volume;

closing the medial filling door and having the medial counting sensor increment the unit count as the unit passes distally over it and record that passage;

using the identifying sensor to compare the observed feature(s) of that unit against the pattern(s) stored in the static memory for the salient feature(s) of that class of unit, thus checking whether this is the right medication;

if the pattern is not matched, the exception for handling an incorrect medication is invoked that unit is discarded, and the steps of sending another unit from the storage volume into the bidirectional dose checking tunnel and checking whether this is the right medication are repeated;

if the pattern is matched, then the unit count is incremented and compared against the dose count to check whether the dosage quantity is right; and

if multiple units are needed then the steps to send and check another unit are repeated, until the incremented unit count matches the dose count;

once the incremented count matches the dose count, the units in the bidirectional dose checking tunnel are passed over the distal counting sensor and the distal filling door is unlatched, so the dose (checked as to both identity of medication and count) is made available for pickup;

if the above steps have been performed independent of human effort then at this point an optional patient alert is sent to the user if he or she had not already received one, letting the patient (user) know that the dose is ready and available;

continuing to count the time through the period of any dosing window;

until either;

(i) a user may, at any time during a dosing window, pick up the device and, through activating the control set seek to obtain the dose scheduled for that dosing window, and when the distal filling door is opened and the medication is removed by the user, the operations cap records that dose and time as having been taken and sets the timer counting towards the next scheduled dose release;

or, (ii) if the dose is not removed before the dosing window is exceeded, then to any set of the prescriber and patient a late dose alert is sent and an exception to the treatment plan is logged into the static memory, and the operations cap latches the distal delivery door (any of the distal filling door and delivery gate), resets the time to the next dose, and sets the timer counting towards the next scheduled dose release.

8. The bi-directional adaptive drug dispenser as in claim 1 wherein said operations cap is programmed to effect delivery of a series of individual doses of one or more units of a medication according to a pre-set regimen and subject to a validation check, and testing and recording the actual performance and behavior, said programming further comprising the steps, at the invocation of a validation check, of:

defaulting to a locked state for any of the latchable door-plus-sensor elements that would allow the removal of anything from the container;

prompting the user to enter, using the control set, the validating authorization;

upon receiving the response determining through the operations cap matching the provided input against the required pattern stored in the static memory, whether or not this specific taking of the medication is authorized;

logging the attempt plus contextual information (time of day, location of container);

If the user is not authorized, then the user is alerted to his invalidity, and an alert reporting the attempt is sent to the prescriber, treating the lack of authorization as an external constraint and, if the user fails to respond or otherwise does not request an exception to the constraint then the operations cap will reset the time for the next scheduled dose release (if the time has elapsed) or keep the timer counting towards the next scheduled dose release (if the time has not elapsed);

but, if the user is authorized, then the operations cap will release the specified latch and thus release the dose; and

set the timer counting towards the next scheduled dose release.

9. The bi-directional adaptive drug dispenser as in claim 1 wherein said operations cap is programmed to effect delivery of a series of individual doses of one or more units of a medication according to a pre-set regimen and for handling of an exception when a constraint of the treatment plan is reached, said programming further comprising the steps of:

the operations cap using, each time that the dock matches up with a time within the limits of the dosing window as stored in the static memory that is, according to the treatment plan, when it is time for a dose to be taken, all data to evaluate whether any specific constraint that would prohibit, or constrain, the taking of that specific dose has be violated;

if no constraint has been violated, then the dose is prepared for the user which if picked up on time results in the operation looping back to and timer counting towards the next scheduled dose release;

but if a constraint has been violated, then;

the operations cap will (a) log the constraint and its violation;

(b) issue an alert to the user; and

(c) issue an alert to the prescriber;

if the user fails to respond or otherwise does not request an exception to the constraint, then the operations cap will reset the time for the next dose and set the times counting towards the next scheduled dose release;

but, if the user does request an exception, then this request is sent to the prescriber, whose response or the lack thereof is logged and, if the exception is approved by the prescriber, the dose is prepared;

while if the exception is not approved, it is not and the operations cap will reset the time for the next dose and set the timer counting towards the next scheduled dose release.

10. The bi-directional adaptive drug dispenser as in claim 1 further comprising any of the set of:

a clock which is settable and programmable through said operations set;

an electromagnetically-driven coil which is controlled by the operations cap, whose activation both transports any unit of medication within the bidirectional dose checking tunnel in a specific direction and is recorded as effecting that specific direction of transfer;
