Assignee:
Southwest Electronic Energy Corporation - Stafford TX
International Classification:
G01R 31/36
US Classification:
702 63, 702 65, 320132
Abstract:
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.

Assignee:
Southwest Electronic Energy Corporation - Stafford TX
International Classification:
G01R 31/36
US Classification:
702 63, 702 65, 320132
Abstract:
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.
Method For Determining Power Supply Usage
US Patent:
8229689, Jul 24, 2012
Filed:
Feb 28, 2011
Appl. No.:
13/036435
Inventors:
Clint Alfred Davis - Houston TX, US
Dean Perkins - Tomball TX, US
Dean Perkins - Tomball TX, US
Assignee:
Southwest Electronic Energy Corporation - Stafford TX
International Classification:
G01R 31/36
US Classification:
702 63, 320132, 320149
Abstract:
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.

Battery Charger
US Patent:
5304916, Apr 19, 1994
Filed:
Apr 11, 1990
Appl. No.:
7/508236
Inventors:
Hung Q. Le - Houston TX
Dean P. Perkins - Tomball TX
Dean P. Perkins - Tomball TX
Assignee:
Compaq Computer Corporation - Houston TX
International Classification:
H02J 700
US Classification:
320 23
Abstract:
A battery charger is provided for use in electronic devices such as a portable computer. When the electronic device is being powered by an external source of power, such as an AC adapter, the battery charger charges the batteries in the electronic device. First, the battery charger checks the batteries to determine if they are capable of holding a charge. Next, the batteries are fully charged. After the batteries have been fully charged, the battery charger maintains the charge on the batteries by supplying low current to the batteries. Moreover, since batteries that are not allowed to discharge tend to lose charge more quickly than batteries that are discharged and recharged often, the battery charger is capable of discharging and then recharging the batteries while the electronic device is being externally powered.
