Abstract: A blender or food processor having electronics associated therewith including at least one controller, at least one current sensor and at least one speed sensor, the controller controls the operation of the blender motor based upon the contents being blended inside the blender jar and compares measured current and speed values and measured changes in the current and speed values to predetermined values stored in memory in order to (1) determine the load size placed in the blender jar, (2) determine if cavitation exists in the blender jar, and (3) determine the final consistency associated with the output of the product placed within the blender jar as selected by the user.

Abstract: A method and apparatus for interactively tuning a transmitter for use in a monitoring station is described. The monitor includes a voltage controlled oscillator producing a radiowave signal for use as a carrier. The voltage used to control the voltage controlled oscillator is provided by a voltage supply that produces an output voltage corresponding to an input data stream. The tuning station provides test data streams to the voltage supply and monitors the output frequencies of the transmitter to determine when the output frequency of the transmitter is above or below the maximum allowable output frequencies. When data streams corresponding to the maximum and minimum output frequencies are determined, they are stored in a memory in the monitoring station and a complete table of temperature-compensated data is generated based upon typical unit temperature drifts. The entire table is loaded into the monitoring station to provide maximum and minimum data sequences for various operating temperature ranges.

Abstract: A method and apparatus for producing a temperature stabilized frequency from a signal generator in a monitoring station is described. The signal generator monitors the voltage response of an RC circuit where the resistive portion is formed by a thermistor, to produce a time-dependent signal. A comparator compares the time-dependent signal to a reference voltage to determine a rise time of the voltage across the capacitor. Based upon a software timer loop, the signal generator determines a temperature range by selecting data from a look-up table based upon the rise time of the RC circuit.
