An ice making machine controller system includes methods and components for making commercial quantities of ice pieces includes adaptive controls responsive to input sensors, output actuators, adaptive ice making control algorithms, adaptive ice harvesting control algorithms, diagnostics for operation cycle monitoring and communicating, and reprogrammable, expanded controller memory for reliable and efficient operation under diverse conditions.

Ice making system, method, and component apparatus

An electronic position sensor for determining position as a function of magnetic flux density. The position sensor includes a magnetic flux sensor and a movable magnet, the sensed magnetic flux density by the magnetic sensor being a function of the relative air gap, magnet thickness, and magnetic field direction between the magnet and the magnet sensor element. The relationship between the magnetic flux density sensed by the magnetic sensing element and the positional disposition of the moved magnet component of the sensor is geometrically defined and optionally linear between two defined points of the range of articulation or motion of the sensor. The magnetic flux sensing element is a Hall-effect integrated circuit, magnetoresistor, magnetodiode, magnetotransistor, or similar sensing element with associated electronic circuitry having adjustable or programmable features including ratiometry, gain, offset voltage, temperature coefficient, and output signal range limiting.

Electronic throttle control position sensor

An integrated electronic starting control system module for diesel engines which provides unique packaging with integration of a multiplicity of features previously unavailable or available only in separate control modules. Integrated into one modular device are improved glow plug and starting system control, monitoring, protection, and diagnostic features. These features for rendering improved glow plug control and diagnostics include: Microprocessor control, adaptive control algorithms, engine analog temperature sensing for glow plug operational compensation, over temperature shut down protection, system glow plug voltage sensing for glow plug operational compensation, timers for control of glow plug operation and duty cycles, sensing of glow plug current for protective shutdown, control relays and/or solid state switches for control of glow plug current(s), manual override control, load dump voltage spike avoidance circuitry based upon alternator output speed, system monitoring with diagnostics communication capability.
