The invention relates to an apparatus and method for tracking energy consumption. An energy tracking system comprises at least one switching element, at least one inductor and a control block to keep the output voltage at a pre-selected level. The switching elements are configured to apply the source of energy to the inductors. The control block compares the output voltage of the energy tracking system to a reference value and controls the switching of the switched elements in order to transfer energy for the primary voltage into a secondary voltage at the output of the energy tracking system. The electronic device further comprises an ON-time and OFF-time generator and an accumulator wherein the control block is coupled to receive a signal from the ON-time and OFF-time generator and generates switching signals for the at least one switching element in the form of ON-time pulses with a constant width ON-time.

A Process Energy Intensity Monitoring and Diagnostic System designed to evaluate the amount of energy input into a process and the resulting product output, and comparing the resulting energy intensity (energy per unit produced) calculation with a statistical average, or preferred value. Further, the system will isolate energy intensity data points that occur outside statistically derived upper or lower control limits. The system will collect information from specific equipment within a manufacturing or production process. This information will be transmitted to the central database that will store, calculate, and deliver real time and historical consumption, production, and energy intensity data to connected client devices. Client devices may include computers, smartphones, or web browsers.

Relative capacitance of a plurality of capacitive sensors may be monitored by using only one ADC conversion. A plurality of capacitive sensors individually charges a sample and hold capacitor. After all of the plurality of capacitive sensors have charged the sample and hold capacitor, a digital conversion of the resulting analog on the sample and hold capacitor is made and stored in a memory. This stored digital collective voltage is compared to a previously stored one and if different then a proximity/touch event may have occurred. Therefore, an entire panel of capacitive sensors may be quickly monitored for a change in the group capacitance thereof, or portions of the capacitive sensors may be monitored for a change in the subgroup capacitance thereof. By knowing which subgroup of capacitive sensors has changed its collective capacitive value, a more focused and selective capacitive sensor measurement can be made that uses less power.
