A load control system provides for automatically controlling a position of a motorized window treatment to control the amount of sunlight entering a space of a building through a window located in a façade of the building in order to control a sunlight penetration distance within the space and minimize occupant distractions. The load control system automatically generates a timeclock schedule having a number of timeclock events for controlling the position of the motorized window treatment during the present day. A user is able to select a desired maximum sunlight penetration distance for the space and a minimum time period that may occur between any two consecutive timeclock events. In addition, a maximum number of movements that may occur during the timeclock schedule may also be entered. The load control system uses these inputs to determine event times and corresponding positions of the motorized window treatment for each timeclock event of the timeclock schedule.

A medication on demand dispenser. The dispenser provides patient access to medications prescribed to be available on an as-needed basis but with a prescribed minimum time interval between doses. The dispenser permits access to a single medication dose after each minimum time interval has elapsed. After a drug dose is presented to the patient, the dispenser prevents access to the next dose until the minimum time interval has elapsed.

A state of charge control system and method uses a region of voltage linearity and a long-term average voltage to estimate an average battery state of charge for storage batteries and to eliminate errors due to hysteresis, drift and sensor noncompliance. An average state of charge Sn is calculated using a current integral method and an average state of charge Sv based on an average observed voltage Vn for a time period exceeding a predefined minimum time but before a predefined maximum time has elapsed is also calculated. If the absolute value of the difference between the Sv and Sn are not are within an acceptable error band, then an offset value is calculated to correct the Sn by subtracting the Sv from the Sn, and thus, to maintain a more accurate Sn. Additionally, a closed current integral method is used to reduce errors due to hysteresis.

A dimmer switch has a user adjustable high-end trim. The dimmer switch includes a bidirectional semiconductor switch, such as a triac, for controlling the amount of power delivered from a source of alternating current power to a lighting load, such as an electric lamp. A user-adjustable timing circuit controls the conduction time of the triac from a minimum time to a maximum time. The maximum possible conduction time of the triac is the high-end trim. The minimum possible conduction time of the triac is the low-end trim. The timing circuit includes a user-accessible switch that allows a user to reduce the high-end trim from a first nominal level to a second reduced level, lower than the first level, without substantially affecting the low-end trim. The switch allows a user to switch a transient voltage suppressor into and out of parallel connection with a resistor that is part of an RC timing circuit for the triac. The dimmer switch advantageously uses less energy and the lifetime of the lamp is extended when the second reduced level of the high-end trim is selected.

A prescription compliance device includes a microcontroller, a program memory storing data representing a plurality of pre-programmed commonly prescribed medication-taking regimens, a selector selecting the regimen and programming the device in accordance therewith, and a display. The selector includes an event switch which is activated in conjunction with a patient taking a dose of a medication corresponding to their regimen to record the taking of the medication. The event switch causes the microcontroller to effect the display of the time at which the next dose of medication is scheduled to be taken, in accordance with the regimen selected by the selector. The microcontroller recalculates the time the next dose is to be taken based on the last time a dose of medication was taken in conjunction with a time change of the prescription compliance device to ensure a medically acceptable minimum time interval is maintained between doses of medication.
