The remaining capacity of a power source, such as a battery, may be monitored with a microprocessor by integrating data received from a current sensor. The microprocessor may measure electrons passing through the battery by sampling the integrator and summing the values recorded from the integrator. Each time the integrator is sampled, the microprocessor may reset the integrator to prevent the integrator from saturating. The microprocessor may sample the integrator when the integrator approaches a predetermined value. The remaining capacity of the battery may be calculated based on calibration values and the sum of electrons measured by the integrator. The remaining capacity may be communicated to remote users through a network and displayed in an executive dashboard.

Power supply usage determination

A system and method for determining a state of a traffic signal. In one embodiment, a traffic signal state detector includes a lens, a color sensor, and a processor. The color sensor is configured to identify a plurality of colors of light directed to the color sensor by the lens, and a field of view of the color sensor is restricted based on dimensions of a traffic signal. The processor is coupled to the color sensor. The processor is configured to determine a color of light emitted by the traffic signal based on the colors of light identified by the color sensor.

The remaining capacity of a battery may be monitored with a microprocessor by integrating a voltage measured across a current sense resistor coupled in series with the battery. The microprocessor may measure electrons passing through the battery by sampling the integrator and summing the values recorded from the integrator. Each time the integrator is sampled, the microprocessor may reset the integrator to prevent the integrator from saturating. The remaining capacity of the battery may be calculated based on calibration values and the sum of electrons measured by the integrator. The remaining capacity may be communicating to remote users through a network and displayed in an executive dashboard.

Method for determining power supply usage

A fuel gauge for power supplies having a voltage pre-regulator; a main voltage regulator; a current sense resistor; an integrator with an op amp and capacitor, wherein the integrator receives power from the main voltage regulator, and receives a voltage proportional to current from the current sense resistor; a microprocessor with data storage and a hysteresis circuit, wherein the microprocessor operates in a low power state until activated by the resistor and the microprocessor converts the voltage proportional to current to a monotonic uni-polar representation of an aggregate number of electrons; a resistor disposed between the integrator and the microprocessor for activating the microprocessor from the low power state prior to saturation of the integrator with the voltage proportional to current; and a reset circuit disposed between the microprocessor and the integrator for resetting the monotonic uni-polar representation of an aggregate number of electrons to zero.

Fuel gauge

A system for counting electrons including a power supply producing a current, a fuel gauge in communication with the power supply, a reader with a reader processor and display, wherein the reader is in communication with a microprocessor of the fuel gauge, and wherein the microprocessor transmits to the reader the established standard engineering unit of capacity, and wherein the reader processor displays the established standard engineering unit of capacity on the display; and a modem in communication with the fuel gauge, wherein the modem provides a communication signal over power lines of the fuel gauge.

System using fuel gauge

A method for counting electrons from a power supply, comprising the following steps: measuring a current of a power supply forming a measured current; converting the measured current to a voltage; then into a monotonic uni-polar representation of an aggregate number of electrons having an amplitude; actuating a microprocessor in communication with a data storage just before an integrator in communication with the power supply reaches a preset limit of aggregate electrons; reading the amplitude forming a reading; transmitting the reading to an accumulator forming an accumulator value; resetting the integrator after the transmitting the reading, repeating the actuation, reading and transmission; comparing the summation of accumulator values to a calibration value; and recording the capacity when the summation of accumulator values meets or exceeds the calibration value.
