20080249724 | SYSTEM AND METHOD OF BATTERY CAPACITY ESTIMATION - In accordance with the teachings described herein, systems and methods are provided for battery capacity estimation. A profile table may be used that relates a plurality of battery profile values with a plurality of operating parameter values. The profile table may be accessed to translate one or more measured operating parameters into one or more corresponding battery profile values. One or more of the battery profile values may be adjusted by a correction factor to generate a corrected battery profile value. The available capacity of the battery may be calculated using the corrected battery profile value. The correction factor may then be automatically calibrated by using an estimated battery profile value calculated from the one or more measured operating parameter. | 10-09-2008 |
20090270049 | System And Methods For Facilitating Instant Communications Over Distributed Cellular Networks - Techniques involving a wireless user device adapted to operate in a carrier network, and associated with a private organization having a private communication network which is not part of the carrier network, are described. The wireless user device gains wireless access via the carrier network and communicates, via the carrier network, with other wireless user devices in a push-to-talk (PTT) voice communication session. The PTT voice communication session is delivered via a carrier processing element of the carrier network, where voice communications of the PTT voice communication session are routed and processed through a private processing element of the private communication network. The voice communications from the wireless user device are assigned and communicated with a generic identifier of the private organization instead of a user identifier of the wireless user device. | 10-29-2009 |
20100048261 | Multifunctional Keyboard For A Mobile Communication Device And Method Of Operating The Same - An apparatus and method for telephony tone signal and character code generation for QWERTY keyboards includes a QWERTY style keyboard, a processor and a keyboard mode control software module. The QWERTY style keyboard has a plurality of letter keys, wherein each letter key is configured to generate a unique input signal. The processor is coupled to the keyboard and is configured to convert each unique input signal generated by the letter keys into a character code and/or a telephony tone signal. The keyboard mode control software module operates on the processor, and controls whether the processor converts the unique input signals from the letter keys into character codes or telephony tone signals. | 02-25-2010 |
20100119018 | Method And Apparatus For Frequency Tracking In A Space Time Transmit Diversity Receiver - A system and method for obtaining a frequency error estimate representing the difference between a reference frequency and the frequency of a space-time transmit diversity signal is disclosed herein. The method includes taking the correlation of total sums, comprised of partial sums taken in defined first and second intervals, to represent the frequency error as the imaginary component of the correlation function. | 05-13-2010 |
20100150098 | Method Of System Access To A Wireless Network - A method includes steps, performed by a wireless device for accessing a wireless network through network base stations. The steps include selecting a reverse link cost metric from a list of reverse link cost metrics. A reverse link cost is determined according to the selected reverse link cost metric. A plurality of base stations are partitioned into a plurality of candidate base stations and a plurality of excluded base stations. The plurality of base stations are substituted with the candidate base stations, thereby reducing the cardinality of the plurality of base stations by the cardinality of the plurality of excluded base stations. A candidate base station is selected from a plurality of the base stations. A probe signal is sent at the reverse link cost to the candidate base station. A response from the candidate base station is waited for within a timeout period. | 06-17-2010 |
