20120114077 | VARIABLE DYNAMIC RANGE RECEIVER - Embodiments of the present invention may provide a signal processing circuit that may comprises an analog-to-digital converter (ADC), and an output restriction circuit. The output restriction circuit may reduce the accuracy of the digital output of the ADC when signal content exceeds a pre-determined spectrum mask in an undesirable band. In one embodiment, the input signal spectrum may be actively monitored and when the input spectrum is inconsistent with an intended application, the output resolution may be restricted, for example, by truncating least significant bits (LSBs) of the digital output or adding digital noise. | 05-10-2012 |

20150044521 | BATTERY CELL WITH DISCRETION TO DRIVE LOADS WITHIN BATTERY STACK - Embodiments of the present invention are directed to improved battery packaging designs. The battery pack design may include a battery cell, a plurality of transistors, and a controller. The transistors may be coupled to the terminals of the battery cell in an H-bridge configuration. The controller may control the transistors to bypass the battery cell based on the current flowing between the output terminals of the battery pack. In such a manner, the controller may prevent damage to the battery cell and improve the overall safety of the battery pack in hazardous conditions. Moreover, the design may allow for more efficient charging/discharging of the cells that are most ready to accept/supply current. | 02-12-2015 |
20150044522 | BATTERY STACK WITH LEAPFROGGING PROTOCOL - Embodiments of the present invention are directed to a battery stack with a leapfrogging communication network. Each cell stage may include a controller, a transmitter, and a pair of receivers. The cell stage in the battery stack may be coupled to the closest two preceding battery cell stages in the stack. In this manner, each cell stage may be able to determine if a fault is present in an immediately preceding cell stage in the stack by monitoring the first preceding cell stage and the second preceding cell stage. If discharge/charge commands transmitted by the second preceding cell stage are not reaching the battery cell stage at issue, the controller may determine that there is a fault in the first preceding cell stage and discharge/charge the cell stage based on the commands transmitted by the second preceding cell stage. | 02-12-2015 |

20100093277 | NEAR FIELD COMMUNICATION SEARCH FOR MOBILE COMMUNICATION DEVICES - A method and apparatus are disclosed for aiding shoppers. A shopper enters a product search query into a hand-held device and, via Near-Field Communication (NFC) technology, transfers the query to a terminal at a shopping establishment. The terminal forwards the search query to a search engine over a network and the search engine, after consulting a database, returns results meeting the criteria of the search query to the terminal for presentation on a display at the terminal. The shopper is then offered the option of transferring the results data, via NFC devices located in the hand-held device and the terminal, from the terminal to a memory in the hand-held device. | 04-15-2010 |
20110096766 | CURRENT CONSUMPTION REDUCTION WITH LOW POWER AMPLIFIER - A transceiver circuit and a method in a wireless communication network are provided, where a signal power level for a signal received at the transceiver circuit is measured and compared to a predefined threshold power level. At least two groups of power amplifiers may be used, where one group is optimized for high efficiency above the predefined threshold power level, and one group is optimized for high efficiency below the predefined threshold power level. The amplifiers may be used to amplify the received signal depending on the signal power level in relation to the predefined power threshold level. The signal may then be filtered by duplex filters and forwarded to a diversity antenna or a main antenna where it is transmitted over an air interface. | 04-28-2011 |
