20090251293 | SYSTEMS AND METHODS FOR MANAGING INVENTORY OF ITEMS HELD IN A CABINET USING RADIO FREQUENCY IDENTIFICATION (RFID) - A RFID cabinet comprises a cabinet structure and one or more drawers or shelves. Chambers are formed within the cabinet to house the one or more drawers or shelves. An RFID scanner is configured to scan items tagged with RFID tags in the chambers via one or more antennas. The antennas can include transmit and receive antennas or antennas configured to perform both transmit and receive functions. The drawers can have a access cover, or lid that can be controlled so as to control access to the drawer. The scanner can be configured to perform inventory control for the tagged items. | 10-08-2009 |

20130254579 | SYSTEM AND METHOD FOR MANAGING ELECTRICAL CURRENT IN A PORTABLE COMPUTING DEVICE - A method and system for managing electrical current within a portable computing device (“PCD”) includes assigning a priority to two or more communications supported by the PCD. A present level of a power supply for the PCD may be monitored by a communications power (“CP”) manager module. Next, the CP manager module may determine if the two or more communications may be transmitted at the present level of the power supply. If the two or more communications cannot be transmitted at the present level of the power supply, then the CP manager module may determine if a timing of at least one of the communications may be adjusted. The CP manager module may also determine a theoretical power level adjustment for at least one of the communications. The two or more communications may be transmitted with any calculated timing off sets and power level adjustments. | 09-26-2013 |

20130275067 | STATE OF CHARGE ERROR CORRECTION SYSTEMS AND METHODS - Systems and methods for determining a state of charge of a battery on a mobile device are disclosed. An exemplary method may include obtaining, when the battery is applying a level of current below a threshold level, an initial state of charge of the battery based upon a measured open circuit voltage value that is applied by the battery. Charge drawn from, and provided to, the battery is monitored from a time after the measured open circuit voltage value is obtained and a state of charge value is calculated when the battery is loaded after the initial open circuit voltage value is obtained based upon the monitored charge. An estimated open circuit voltage for the battery is calculated based upon simultaneous measurements of battery voltage and battery current, and a corrected state of charge value is generated using the estimated open circuit voltage. | 10-17-2013 |
20140028285 | METHOD AND APPARATUS FOR TEMPERATURE ADJUSTED CONTROL OF BATFET CURRENT SENSING - A method and apparatus for providing a temperature sensing loop used in connection with a current sensing component, such as a BATFET, in order to compensate for variations in the BATFET's resistance due to temperature variations. The temperature sensing loop detects a temperature of the BATFET and regulates the gate voltage of the BATFET based on the detected temperature in order to compensate for changes in the BATFET's resistance. The temperature sensing feedback loop maintains the BATFET at a constant resistance for current sensing through negative feedback control. The BATFET and temperature sensing loop can be provided as components of an on-chip fuel gauging application for a UE. | 01-30-2014 |
20140055082 | CHARGING CURRENT CALIBRATION - Exemplary embodiments are directed to systems, devices, methods, and computer-readable media for calibrating a charging current. A device may include a charger for conveying an output voltage to a chargeable device. The device may also include a monitoring system including an analog-to-digital converter for measuring a current received by the chargeable device. Further, the device may include a control device configured to receive a charging current value from the monitoring system and convey a signal to the charger in response to a comparison of the charging current value to a target current value. | 02-27-2014 |
20140172333 | SYSTEMS AND METHODS FOR STATE OF CHARGE ESTIMATION - The present disclosure includes systems and methods for state of charge estimation. In one embodiment, the present disclosure includes a method comprising receiving a voltage corresponding to a state of charge of a battery, converting the voltage to an estimated state of charge using different algorithms across different ranges. In another embodiment, an offset state of charge is applied to a first state of charge to produce an estimated state of charge. | 06-19-2014 |
20150046105 | VOLTAGE MODE FUEL GAUGE - In one embodiment, a circuit comprises a sensor providing a digital signal responsive to a battery voltage on a battery terminal of a battery. The sensor can be an analog-to-digital convertor. A processor is coupled to the sensor and is configured to calculate a state of charge of the battery based on the digital signal at a first time, the digital signal at a second time, and a stored battery profile of open circuit voltage as a function of state of charge at the second time. | 02-12-2015 |

20130227327 | System and Method For Managing Electrical Current In A Portable Computing Device - An electrical current (“EC”) manager module may assign a plurality of hardware elements of the PCD to one of two groups. The EC manager module may monitor individual electrical current levels of one of the groups as well as calculate an instantaneous electrical current level for the PCD based on a current charge status for the PCD. The EC manager module may then adjust operation of at least one hardware element to keep operation of the PCD below the calculated instantaneous electrical current level for the PCD. The EC manager module may estimate an electrical current level for one of the groups based on requests issued to hardware elements. The EC manager module may also compare the calculated instantaneous electrical current level to the monitored electrical current level. The calculated instantaneous electrical current level may be compared to minimum current levels listed in a table. | 08-29-2013 |
