Abstract: A medical timer apparatus that provides a time of day display and that measures time as between sensings of a monitored parameter, such as the opening of a medication container. Alarm time information may be input as either preselected times of day or as an interval between openings of the medication container. A minimum safe interval between dosages unit operates to signal when medication should not be taken. A predosing interval unit operates to signal the operator that medication might be safely dispensed even though the alarm time has not yet arrived. The invention also operates to calculate and display a compliance score that indicates how well the patient has complied wtih the prescription schedule.

Abstract: A digital watch including a clocking signal generator is disclosed wherein a control circuit provides phasing signals for multiplexing data representing seconds, minutes, hours, and data information in successive cycles to a visual display panel. In the normal mode of operation of the watch, minutes and hours are displayed. The watch further includes circuitry for selectively displaying seconds and date information as well as for setting the hours, minutes, and date. The aforementioned functions require the utilization of only three functional switches which may be incorporated into a stem of the watch. By selectively closing and opening one switch, as for example, pushing in and releasing the stem, seconds information is first displayed and then the date information is momentarily displayed for a predetermined interval after which the watch returns to a normal mode of operation of displaying hours and minutes.

Abstract: An improved electronic watch module easily manufactured and easily repaired has a housing lower half containing at least one watch integrated circuit electrically connected to a quartz crystal and a potential source. A switch in the housing lower half is used for operating the watch, i.e., for setting the time as well as providing minutes and seconds on demand rather than hours and minutes normally displayed. A housing upper half contains a liquid crystal display element and means for electrically interconnecting the display element and the at least one watch integrated circuit in the housing lower half. Releasable means fastens the housing lower and upper halves in assembled relationship. The upper and lower housing halves may be separately assembled and tested to insure proper operation prior to fastening them together.
