Abstract:
A “Real-Time-Ready Analyzer” combines a data stream management system (DSMS) with a map-reduce (M-R) framework to construct a streaming map-reduce framework that is suitable for real-time Behavioral Targeting (BT) (or other temporal queries). The Real-Time-Ready Analyzer allows users to write “dual-intent” temporal analysis queries for BT. These queries are succinct and easy to express, scale well on large-scale offline data, and can also work over real-time data. Further, the Real-Time-Ready Analyzer uses the aforementioned streaming map-reduce framework to provide dual-intent algorithms for end-to-end BT phases. Experiments using real data from an advertisement system show that the Real-Time-Ready Analyzer is very efficient and incurs orders-of-magnitude lower development effort than conventional systems.
Abstract:
A transmitter for a mobile device utilizes at least one mapper in order to improve power efficiency while still meeting out of band spurious emissions and waveform quality requirements. An encoder and modulator generates an encoded and modulated transmit signal from an input signal. A digital to analog converter coupled to the encoder and modulator generates an analog representation of the encoded and modulated transmit signal. An amplifier stage coupled to the digital to analog converter amplifies the analog representation of the encoded and modulated transmit signal to generate a transmission signal. The transmitter further comprises an amplifier control block configured to generate an amplifier control signal for adjusting at least one parameter of the amplifier stage. At least one mapper is provided in the amplifier control block, used to determine the amplifier control signal based on a peak to average power ratio and an average transmit power of the transmission signal. Environmental and operating conditions of the transmitter may be accounted for as well in the mappers.
Abstract:
A system and method are disclosed for embedding a timing controller on column drivers which, among other advantages, reduces power consumption and size constraints. A standalone timing controller is eliminated by splitting a video input signal and delivering the signal to each of the column drivers. Timing controller functionality is embedded in each of the column drivers to allow the column drivers to process the received video signal. An auxiliary input used for communication between column drivers and an external system is received by a master column driver. The master column driver communicates with slave column drivers to enable point to point communication between each column driver and the external system.
Abstract:
Systems and methods can be implemented on a user device and eNBs to manage uplink interference. A user device associated with a serving base station may detect downlink interference from one or more interfering base stations that are different from the serving base station. The user device that detects downlink interference can determine an uplink radio resource set from a plurality of predefined uplink radio resource sets based, at least in part, on the detected downlink interference. The user device can then transmit to the serving base station a radio resource indication identifying the determined uplink radio resource set to facilitate uplink interference management.
Abstract:
A communication device reads and stores in memory a state value which was utilized for operating a communication subsystem during a wake-up period of the communication subsystem. The device then causes the communication subsystem to enter into a sleep mode. Subsequently, the device causes the communication subsystem to exit from the sleep mode and enter into a current wake-up period. The stored state value is provided to the communication subsystem for use in operating the communication subsystem during a warm-up period of the current wake-up period. After the warm-up period of the current wake up period, a current state value is provided from a state controller to the communication subsystem for use in operating the communication subsystem during the wake up period. The current state value is determined based on a detected signal level of a current signal received in the communication subsystem.
Abstract:
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.
Abstract:
Techniques for use in a mobile device for obtaining location information with use of a Global Positioning System (GPS) involve receiving, through a user interface of the mobile device, a voice call request for establishing a voice call; and in response to receiving the voice call request: comparing a selected telephone number of the voice call request with one or more predetermined telephone numbers stored in memory of the mobile device; if the selected telephone number matches one of the predetermined telephone numbers stored in the memory: prior to initiating the voice call, performing a GPS fix with the GPS system for obtaining the location information of the mobile device; if the selected telephone number fails to match one of the predetermined telephone numbers stored in the memory: refraining from performing the GPS fix for obtaining the location information of the mobile device prior to establishing the voice call; and initiating the voice call from the mobile device via a wireless network.
Abstract:
A method includes measuring an operating parameter of a battery of a mobile device. The measured operating parameter is translated into an equivalent series resistance (ESR) value. The ESR value is adjusted by a correction factor to generate a corrected ESR value. The capacity of the battery is determined based on the corrected ESR value. The correction factor is automatically calibrated based on the measured operating parameter.
Abstract:
In one illustrative example, methods and apparatus for use in buffering PTT voice communications are described. A mobile station sends a PTT voice communication request in a wireless communication network. Prior to receiving a floor grant in response to the PTT voice communication request, the mobile station receives voice input signals and buffers digital voice data corresponding to the voice input signals, where the digital voice data is produced by encoding and compressing the voice input signals. The mobile station receives the floor grant in response to the PTT voice communication request. Upon receipt of the floor grant, the mobile station retrieves the buffered digital voice data and continues to buffer digital voice data corresponding to the voice input signals, until all of the buffered digital voice data has been sent.
Abstract:
A method and apparatus for estimating oscillator signal variation due to temperature and for providing an estimated frequency to a GPS receiver in order to assist the GPS receiver to acquire the signals quickly is disclosed. A temperature sensor is closely thermally coupled with the crystal oscillator in the GPS receiver and during GPS tracking mode, when the error in the oscillator signal is known with precision, outer bounds of TCXO frequency at given temperatures are maintained, which may correspond to rising and falling temperature conditions. During acquisition mode, an estimated frequency value is provided to the GPS receiver based on a determined average of these bounds. Optionally, an uncertainty factor associated with the frequency estimated may also be provided. The two bounds take into account the hysteresis effects of the oscillator signal drift due to temperature so that a more accurate initial frequency estimate can be provided to the GPS receiver, thus reducing its average time to first fix.
