Abstract: The present invention comprises a system and method for dynamically scheduling patient medical facility appointments. The present invention is capable of contacting patients to ensure that each patient will be present for the appointment and is capable of dynamically adjusting the schedule in the event the patient plans to be late or plans to cancel the appointment. The present invention is also capable of contacting patients to reschedule appointments in the event that their medical service provider unexpectedly becomes unavailable. The system's scheduling method has the effect of increasing medical facility efficiency and standardizing medical facility wait time for the patients and thereby increasing profitability and increasing patient convenience.

Abstract: A refrigerator having a cabinet defining a first compartment and a second compartment separated from each other by a divider wall wherein the divider wall has an air passage for communicating between the first and second compartments. The refrigerator further includes an evaporator disposed in the first compartment, a compressor fluidly connected with the evaporator for moving refrigerant therethrough, and an evaporator fan for moving air over the evaporator. A first thermostat senses temperature within the first compartment and a second thermostat senses temperature within the second compartment. An evaporator fan and baffle control system is provided including a baffle disposed within the air passage and being positionable in an open or closed position for selectively opening and closing the air passage.

Abstract: A method of energizing a relay comprising the steps of applying an energization signal to the relay having a voltage in excess of a rated voltage of the relay and then allowing the energization voltage to rapidly decay to a level within the rated voltage of the relay.

Abstract: A defrost cycle controller for a refrigeration system encompassing a compressor; a defrost heater; a thermostatic switch coupled in series with said compressor to control operation of said compressor; a bimetallic switch coupled in series with said defrost heater to control operation of said defrost heater; and a relay coupled to mutually exclusively couple the compressor or defrost heater to a power supply, the relay having a normally closed contact which is in series with said compressor and a normally open contact coupled in series with said defrost heater.

Abstract: A defrost cycle controller for a refrigerator or freezer having a compressor and a defrost heater, comprising a relay operatively connected to the compressor and the defrost heater via contacts to couple one or the other to a power supply, the relay having a normally closed contact to which said compressor is connected and a normally open contact to which said defrost heater is connected; and a control circuit operatively connected to the compressor, defrost heater and relay and configured to implement the following algorithm: (a) first, energize the relay; (b) second, monitor the relay contacts; (c) third, if the contacts do not change states, de-energize the relay; and (d) fourth, rest for a predetermined period, and then commence the algorithm.
