Abstract: Disclosed herein are novel drug carriers including a non-aqueous pH dependent release system and a non-aqueous pH dependent reassembly/assembly and reabsorption/absorption system. The carriers are capable of pH dependent release of biologically active agents and assembly or reassembly when the carrier transitions from a low pH environment, to a high pH environment and back to a low pH environment.

Abstract: An eyelid movement detector, includes one electrode to be placed above each eyebrow of an individual and a third electrode to serve as a ground or reference. The electrodes sense eyelid muscle activity and produce a voltage in response to eyelid movement, indicative of a state of awareness. The sensed voltage produced is amplified and compared to a threshold reference voltage by a comparator, which produces a control signal if the sensed voltage is greater than the threshold voltage. The control signal resets a timer. If the timer is not reset within a predetermined time interval, an alarm is activated to warn an individual.
