Abstract: A write driver circuit selectively provides a write current through a write head in first and second opposite directions. The write driver circuit is connected to the write head through an interconnect. The write driver circuit provides an incident write current signal through the interconnect to the write head, and also provides a reflection cancellation signal through the interconnect to the write head. In an exemplary embodiment, the incident write current signal is provided by providing an incident voltage signal across the write head, and the reflection cancellation signal is provided by providing a reflection cancellation voltage signal across the write head. In an exemplary embodiment, the reflection cancellation signal is a delayed and filtered version of the incident write current signal that cancels a reflected signal that is reflected at the interface between the interconnect and the write head due to impedance mismatching.

Abstract: A controller for controlling a heater associated with the crankcase of a compressor senses electrical current flowing through the heater. The sensing is preferably accomplished by a transformer in combination with an amplifier providing a feedback signal to the controller. The transformer is installed in the line which carries the electrical current flowing through the heater. The controller checks for the presence of an appropriate voltage level from the amplifier. In the event that the voltage level is not above a threshold level, the controller sends an alarm signal indicating that the heater is not operating properly.
